Bill Gates - A Successful Entrepreneur

William (Bill) H. Gates III is chairman of Microsoft Corporation, the worldwide leader in software, services and solutions that help people and businesses realize their full potential. Microsoft had revenues of US$55.12 billion for the fiscal year ending June 2007, and employs more than 78,000 people in 105 countries and regions.

Entrepreneur Bill Gates, born on October 28, 1955, in Seattle, Washington, began to show an interest in computer programming at the age of 13. Through technological innovation, keen business strategy, and aggressive competitive tactics, he and his partner Paul Allen built the world's largest software business, Microsoft. In the process, Bill Gates became one of the richest man in the world.

Early Life

William Henry Gates III, Born on October 28, 1955, in Seattle, Washington. Gates began to show an interest in computer programming at the age of 13 at the Lakeside School. He pursued his passion through college. Striking out on his own with his friend and business partner Paul Allen, Gates found himself at the right place at the right time. Through technological innovation, keen business strategy, and aggressive competitive tactics he built the world's largest software business, Microsoft. In the process he became one of the richest men in the world.

Bill Gates grew up in an upper middle-class family with two sisters: Kristianne, who is older, and Libby, who is younger. Their father, William H. Gates, Sr., was a promising, if somewhat shy, law student when he met his future wife, Mary Maxwell. She was an athletic, outgoing student at the University of Washington, actively involved in student affairs and leadership. The Gates family atmosphere was warm and close, and all three children were encouraged to be competitive and strive for excellence. Bill showed early signs of competitiveness when he coordinated family athletic games at their summer house on Puget Sound. He also relished in playing board games (Risk was his favorite) and excelled in Monopoly.

Bill had a very close relationship with his mother, Mary, who after a brief career as a teacher devoted her time to helping raise the children and working on civic affairs and with charities. She also served on several corporate boards, among them First Interstate Bank in Seattle (founded by her grandfather), the United Way, and International Business Machines (IBM). She would often take Bill along on her volunteer work in schools and community organizations.

Bill was a voracious reader as a child, spending many hours pouring over reference books such as the encyclopedia. Around the age of 11 or 12, Bill's parents began to have concerns about his behavior. He was doing well in school, but he seemed bored and withdrawn at times. His parents worried he might become a loner. Though they were strong believers in public education, when Bill turned 13 they enrolled him in Seattle's Lakeside School, an exclusive preparatory school. He blossomed in nearly all his subjects, excelling in math and science, but also doing very well in drama and English.

While at Lakeside School, a Seattle computer company offered to provide computer time for the students. The Mother's Club used proceeds from the school's rummage sale to purchase a teletype terminal for students to use. Bill Gates became entranced with what a computer could do and spent much of his free time working on the terminal.

He wrote a tic-tac-toe program in BASIC computer language that allowed users to play against the computer. 

It was at Lakeside School where Bill met Paul Allen, who was two years his senior. The two became fast friends, bonding on their common enthusiasm over computers, even though they were very different. Allen was more reserved and shy. Bill was feisty and at times combative. They both spent much of their free time together working on programs. Occasionally,

they disagreed and would clash over who was right or who should run the computer lab. On one occasion, their argument escalated to the point where Allen banned Gates from the computer lab. On another occasion, Gates and Allen had their school computer privileges revoked for taking advantage of software glitches to obtain free computer time from the company that provided the computers. After their probation, they were allowed back in the computer lab when they offered to debug the program. During this time, Gates developed a payroll program for the computer company the boys hacked into, and a scheduling program for the school. 

In 1970, at the age of 15, Bill Gates went into business with his pal, Paul Allen. They developed "Traf-o-Data," a computer program that monitored traffic patterns in Seattle, and netted $20,000 for their efforts. Gates and Allen wanted to start their own company, but Gates' parents wanted him to finish school and go on to college where they hoped he would work to become a lawyer. 

Bill Gates graduated from Lakeside in 1973. He scored 1590 out of 1600 on the college SAT test, a feat of intellectual achievement that for several years he boasted about when introducing himself to new people.

Early Career

Gates enrolled at Harvard University in the fall, originally thinking of a career in law. But his freshman year saw him spend more of his time in the computer lab than in class. Gates did not really have a study regimen. Instead, he could get by on a few hours of sleep, cram for a test, and pass with a reasonable grade.

Gates remained in contact with Paul Allen who, after attending Washington State University for two years, dropped out and moved to Boston, Massachusetts, to work for Honeywell. In the summer of 1974, Gates joined Allen at Honeywell. During this time, Allen showed Gates an edition of Popular Electronics magazine featuring an article on the Altair 8800 mini-computer kit. Both boys were fascinated with the possibilities this computer could make toward personal computing. The Altair was made by a small company in Albuquerque, New Mexico, called Micro Instrumentation and Telemetry Systems (MITS). Gates and Allen contacted the company proclaiming they were working on a BASIC software program that would run the Altair computer. In reality, they didn't have an Altair to work with or the code to run it. But they wanted to know if MITS was interested in someone developing such software. MITS was, and its president Ed Roberts asked the boys for a demonstration.

Gates and Allen scrambled, and spent the next two months writing the software at Harvard's computer lab. Allen traveled to Albuquerque for a test run at MITS, never having tried it out on an Altair computer. It worked perfectly. Allen was hired at MITS and Gates soon left Harvard to work with him, much to his parents' dismay. In 1975, Gates and Allen formed a partnership they called Micro-Soft,

Microsoft (Gates and Allen dropped the hyphen in less than a year) started off on shaky footing. Though their BASIC software program for the Altair computer netted the company a fee and royalties, it wasn't meeting their overhead. Microsoft's BASIC software was popular with computer hobbyists who obtained pre-market copies and were reproducing and distributing them for free. According to Gates' later account, only about 10 percent of the people using BASIC in the Altair computer had actually paid for it. At this time, much of the personal computer enthusiasts were people not in it for the money. They felt the ease of reproduction and distribution allowed them to share software with friends and fellow computer enthusiasts. Bill Gates thought differently. He saw the free distribution of software as stealing, especially when it involved software that was created to be sold. 

In February of 1976, Gates wrote an open letter to computer hobbyists saying that continued distribution and use of software without paying for it would "prevent good software from being written." In essence, pirating software would discourage developers from investing time and money into creating quality software. The letter was unpopular with computer enthusiasts, but Gates stuck to his beliefs and would use the threat of innovation as a defense when faced with charges of unfair business practices. 

Gates had a more acrimonious relationship with MITS president Ed Roberts, often resulting in shouting matches. The combative Gates clashed with Roberts on software development and the direction of the business. Roberts considered Gates spoiled and obnoxious. In 1977, Roberts sold MITS to another computer company, and went back to Georgia to enter medical school and become a country doctor. Gates and Allen were on their own. The pair had to sue the new owner of MITS to retain the software rights they had developed for Altair. 

Microsoft wrote software in different formats for other computer companies and, at the end of 1978, Gates moved the company's operations to Bellevue Washington, just east of Seattle. Bill Gates was glad to be home again in the Pacific Northwest, and threw himself into his work. All 25 employees of the young company had broad responsibilities for all aspects of the operation, product development, business development, and marketing. With his acumen for software development and a keen business sense, Gates placed himself as the head of Microsoft, which grossed $2.5 million in 1978. Gates was only 23.

The Rise of Microsoft

Gates' acumen for not only software development but also business operations put him in the position of leading the company and working as its spokesperson. He personally reviewed every line of code the company shipped, often rewriting code when he saw it necessary. As the computer industry began to grow with companies like Apple, Intel, and IBM developing hardware and components,

Bill was continuously out on the road touting the merits of Microsoft software applications. He often took his mother with him. Mary was highly respected and well connected with her membership on several corporate boards including IBM. It was through Mary that Bill Gates met the CEO of IBM.

In November 1980, IBM was looking for software that would operate their upcoming personal computer (PC) and approached Microsoft. Legend has it that at the first meeting with Bill Gates someone at IBM mistook him for an office assistant and asked him to serve coffee. Gates did look very young, but he quickly impressed IBM, convincing them that he and his company could meet their needs. The only problem was that Microsoft had not developed the basic operating system that would run IBM's new computers. Not to be stopped, Gates bought an operating system that was developed to run on computers similar to IBM's PC. He made a deal with the software's developer, making Microsoft the exclusive licensing agent and later full owner of the software but not telling them of the IBM deal. The company later sued Microsoft and Gates for withholding important information. Microsoft settled out of court for an undisclosed amount, but neither Gates nor Microsoft admitted to any wrong doing.

Gates had to adapt the newly purchased software to work for the IBM PC. He delivered it for a $50,000 fee, the same price he had paid for the software in its original form. IBM wanted to buy the source code, which would have given them the information to the operating system. Gates refused, instead proposing that IBM pay a licensing fee for copies of the software sold with their computers. Doing this allowed Microsoft to license the software they called MS-DOS to any other PC manufacturer, should other computer companies clone the IBM PC, which they soon did. Microsoft also released software called Softcard, which allowed Microsoft BASIC to operate on Apple II machines.

Between 1978 and 1981, Microsoft's growth exploded, and staff increased from 25 to 128. Revenue also shot up from $4 million to $16 million. In mid-1981 Gates and Allen incorporated Microsoft, and Gates was appointed president and chairman of the board. Allen was named executive vice-president.

By 1983, Microsoft was going global with offices in Great Britain and Japan, and with 30 percent of the world's computers running on its software. But 1983 also brought news that rocked Microsoft to its very foundation. Paul Allen was diagnosed with Hodgkin's disease. Though his cancer went into remission a year later with intensive treatment, Allen resigned from company that same year.

Rumors abound as to why Allen left Microsoft. Some say Bill Gates pushed him out, but many say it was a life-changing experience for Allen and he saw there were other opportunities that he could invest his time in.

The Invention of Microsoft Windows

Though their rivalry is legend, Microsoft and Apple shared many of their early innovations. In 1981 Apple invited Microsoft to help develop software for Macintosh computers. Some developers were involved in both Microsoft develeopment, and the development of Microsoft applications for Macintosh. The collaboration could be seen in some shared names between the Microsoft and Macintosh systems. 

It was through this knowledge sharing that Microsoft was to develop Windows. A system was that used a mouse to drive a graphic interface, displaying text and images on the screen. This differed greatly from the text and keyboard driven MS-DOS system where all text formatting showed on the screen as code and not what actually would be printed. Bill Gates quickly recognized the threat this kind of software might pose for MS-DOS and Microsoft overall. For the unsophisticated user—which was most of the buying public—the graphic imagery of the VisiCorp software would be so much easier to use. Gates announced in an advertising campaign that a new Microsoft operating system was about to be developed that would use a graphic interface. It was to be called "Windows," and would be compatible with all PC software products developed on the MS-DOS system. The announcement was a bluff, in that Microsoft had no such program under development. But as a marketing tactic it was sheer genius as nearly 30 percent of the computer market was using the MS-DOS system and would wait for Windows software rather than change to a new system. Without people willing to change formats, software developers were unwilling to write programs for the VisiCorp system and it lost momentum by early 1985.

In November 1985, Bill Gates and Microsoft launched Windows; nearly two years after his announcement. Visually the Windows system looked very similar to the Macintosh system Apple Computer Corporation had introduced nearly two years earlier. Apple had earlier given Microsoft full access to their technology while it was working on making Microsoft products compatible for Apple computers. Gates had advised Apple to license their software but they ignored the advice, being more interested in selling computers. Once again, Gates took full advantage of the situation and created a software format that was strikingly similar to the Macintosh. Apple threatened to sue and Microsoft retaliated, saying it would delay shipment of its Microsoft compatible software for Macintosh users. In the end, Microsoft prevailed in the courts because it could prove that while there were similarities in how the two software systems operated, each individual function was distinctly different.

In 1986, Bill Gates took Microsoft public with an initial public offering (IPO) of $21 per share. Gates held 45 percent of the company's 24.7 million shares and became an instant millionaire at age 31. Gates' stake at that time was $234 million of Microsoft's $520 million.

Over time, the company's stock increased in value and split numerous times. In 1987, Bill Gates became a billionaire when the stock raised to $90.75 a share. Since then, Gates has been on the top or near the top of Forbes' 400 list of the world's wealthiest people. In 1999, with stock prices at an all time high and the stock splitting eight-fold since its IPO, Gates' wealth briefly topped $101 billion. 

Yet,Bill Gates never felt totally secure about the status of his company. Always having to look over his shoulder to see where the competition was, he developed a white hot drive and competitive spirit. Gates expected everyone in the company to have the same drive and dedication. One story goes that one of Gates' assistants had come to work early to find someone sleeping under a desk. She considered calling security or the police when she discovered it was Gates. 

Bill Gates' intelligence allowed him to be able to see all sides of the software industry—product development and corporate strategy. When analyzing any corporate move, he would develop a profile of all the possible cases and run through them, asking questions about anything that could possibly happen. His confrontational management style became legend as he would challenge employees and their ideas to keep the creative process going. An unprepared presenter would hear, "That's the stupidest thing I've ever heard!" from Gates. But this was as much a test of the rigor of the employee as it was Gates' passion for his company. He was constantly testing the people around him to see if they were really convinced of their ideas. 

Outside the company, Bill Gates was gaining a reputation as a ruthless competitor. Several tech companies led by IBM began to develop their own operating system called OS/2 to replace MS-DOS. Rather than give into the pressure, Gates pushed ahead with the Windows software, improving its operation and expanding its uses. In 1989, Microsoft introduced Microsoft Office which bundled office productivity applications such as Microsoft Word and Excel into one system that was compatible with all Microsoft products. The applications were not as easily compatible with OS/2. Microsoft's new version of Windows sold 100,000 copies in just two weeks and OS/2 soon faded away. This left Microsoft with a virtual monopoly on operating systems for PCs. Soon the Federal Trade Commission began to investigate Microsoft for unfair marketing practices. 

Microsoft faced a string of Federal Trade Commission and Justice Department investigations throughout the 1990s. Some related allegations that Microsoft made unfair deals with computer manufactures who installed the Windows operating system on their computers. Other charges involved Microsoft forcing computer manufactures to sell Microsoft's Internet Explorer as a condition for selling the Windows operating system with their computers. 

At one point, Microsoft faced a possible break up of its two divisions—operating systems and software development.

Microsoft defended itself, harking back to Bill Gates' earlier battles with software piracy, and proclaiming that such restrictions were a threat to innovation. Eventually, Microsoft was able to find a settlement with the federal government to avoid a breakup. Through it all,

Gates found some inventive ways to deflect the pressure with light-hearted commercials and public appearances at computer trade shows posing as Star Trek's Mr. Spock. Gates continued to run the company and weather the federal investigations through the 1990s.

Personal Life

In 1989, a 28-year-old Microsoft executive named Melinda French caught the eye of Bill Gates, then 37. The very bright and organized Melinda was a perfect match for Gates. In time, their relationship grew as they discovered an intimate and intellectual connection. On January 1, 1994, Melinda and Bill were married in Hawaii. But only a few months later heartbreak struck Bill Gates as his mother was diagnosed with breast cancer. She died in June 1994. Gates was devastated.

Bill and Melinda took some time off in 1995 to travel to several countries and get a new perspective on life and the world. In 1996, their first daughter, Jennifer, was born. A year later, Gates moved his family into a 55,000 sq ft. $54 million house on the shore of Lake Washington. Though the house serves as a business center, it is said to be a very cozy home for the couple and their three children.

Philanthropic Efforts

With the influence of his wife Melinda, Gates took an interest in filling his mother's role as a civic leader. He began to realize that he had an obligation to give more of his wealth to charity. Being the consummate student he was, Gates studied the philanthropic work of Andrew Carnegie and John D. Rockefeller, titans of the American industrial revolution. In 1994, Gates and his wife established the William H. Gates Foundation which was dedicated to supporting education, world health, and investment in low-income communities. In 2000, the couple combined several family foundations to form the Bill and Melinda Gates Foundation. They started out by making a $28 billion contribution to set up the foundation.

Bill Gates stepped down from the day-to-day operations of Microsoft in 2000, turning over the job of CEO to college friend Steve Ballmer who had been with Microsoft since 1980. He positioned himself as chief software architect so he could concentrate on what was for him the more passionate side of the business. He still remains chairman of the board. Over the next few years, his involvement with the Bill and Melinda Gates Foundation occupied much of his time and even more of his interest. In 2006, Gates announced he was transitioning himself from full-time work at Microsoft, to devote more quality time to the Foundation. His last full day at Microsoft was June 27, 2008.

In addition to all the accolades of being one of the most successful and richest businessmen in the history of the world, Bill Gates has also received numerous awards for philanthropic work. Time magazine named Gates one of the most influential people of the 20th century. The magazine also named Gates, his wife Melinda, and rock band U2's lead singer Bono as the 2005 Persons of the Year.

Gates also holds several honorary doctorates from universities throughout the world and an honorary Knight Commander of the Order of the British Empire by Queen Elizabeth II. In 2006, Gates and his wife were awarded the Order of the Aztec Eagle by the Mexican government for their philanthropic work throughout the world in the areas of health and education.

Bill Gates Achievements

Hacking and its types

The unceasing quest of human mind has conceived to almost all crucial inventions of the world. Hacking dates back its inception to the same human urge to know and hence explore things. Computer Hacking is a practice of peeping into the extreme technical details of any computer application, program, or the whole system in order to extend its capabilities or alter its functionalities. People who rightly follow this practice of hacking are termed as ‘hackers’. A hacker’s vision towards solving any technical problem is undoubtedly beyond the perception of any normal computer expert. The open-source coding has been very beneficial for hackers to test and invent out of their passion for programming, say UNIX is the best example.

This practice can either be ethical or unethical. The activity where one breaks into the system but do not violate its security and credentials is called Ethical Hacking. Ethical hackers aim to bring into the administrator’s notice, vulnerabilities and voids in the system thereby, improvising the robustness and security. They are purely tech-geeks with immaculate programming skills and hands-on knowledge on both computer hardware and software. On the other hand, there are people of dark side who can though break into systems, get access to secured accounts but their actions are usually unauthorized while they make a backdoor entry into your system. These people (often misinterpreted as hackers) are called as ‘crackers’ or ‘intruders’. They try and crack passwords, security codes, etc using various hacking softwares which are already available. Such softwares are meant to break the code using millions of trials programmed into it by other hackers.

Hacker metholodogy

While hacking can prove really useful when companies hire hackers to keep a check on the security of their network and transactions, it may be equally harmful even to an individual operating his/her personal computer sitting at home.

Footprinting

What is the first step one would take before seeking admission in a university or college? Quite unanimously, it must be a primary research about the institute.

Footprinting is an analogous step which hackers take before gaining access into any network. The systematic footprinting of an organization enables attackers to create a complete profile of an organization’s security posture like system architecture, network blocks and IP addresses exposed on the Internet. Hackers gain reconnaissance of the target following a sequence of steps as:
1. Open Source Footprinting - The first step a hacker takes is to visit the website of a potential target. He then looks for contact information of the administrators which may help in guessing the password or in Social Engineering.
2. Network Enumeration - This is the next step in gaining information where the hacker tries to identify the domain names and the network blocks of the target network.
3. Scanning - Once the network block is known, the next step is to spy for active IP addresses on the target network. The Internet Control Message Protocol (ICMP) is a good alternative for identifying active IP addresses.
4. Stack Fingerprinting - Once the hosts and port have been mapped by scanning the target network, the final footprinting step can be performed. This step is called stack fingerprinting. This is the process of determining the operating system and different version of services running on target hosts.

There are different ways a hacker can attack a system in order to gain access which may be:
·         A backdoor program entry.
·         Through unauthorized executable files called viruses and worms
·         Phishing
·         Password Cracking
·         Denial-of- Service (DoS) attack , or
·         Fake web pages
·         The TRINOO Attack

In a backdoor program entry the hacker gets access to your programs, files, personal details, browsing details etc and easily make all sort of possible changes to them like editing, deleting, copying. And alas! The user whose machine is at compensation may not even realize that he is been hacked. Such backdoor entries are installed on the targeted machine usually through alluring user executable files called ‘Trojan’. Well the art of hacking lies in designing these malicious programs called Trojan which aims at monitoring and controlling the target computer unofficially.

Hacking through viruses and worms is quite self-explanatory and is the most common way to infect a target machine. Viruses and worms both are malicious programs that can affect your system but there is a slight difference in the way they affect the system. A virus, like the human viruses is attached with the executable files and programs and has ability to travels from one system to another. The important characteristic of a virus is that it affects your system or files only if you run or open the malicious program. Whereas worm is a sub category of viruses that can replicate themselves and travels from one system to another with other files and data. Worms do not need any human interaction to affect your system i.e. they can affect your system even if you do not run or open the malicious program. For example a worm can send a copy of itself to everyone listed in your email address and then by replicating itself again and send to everyone from your receivers address book. Hence it can affect an entire network very rapidly and is more dangerous form of viruses.

Phishing is another smart hacking technique used as a baited trap by hackers to steal your personal details like name, address, passwords, credit card numbers, etc. Hackers create phishing sites with familiar logos, mottos and graphics which are fake web pages but look similar to their own bank or usual surfing stuffs and excite users to enter their personal details. They may even mail you fake messages demanding to recover your lost details. Again a trap..!! So users, beware of such baits. Do not respond to any such mails and do check for a lock sign in the URL before entering your personal details. Legitimate websites always use this sign to indicate a secure connection.

Password Cracking is the easiest way to gain access to a system. There are two modes of password cracking; online and offline. In online guessing attempt, the attacker uses a login prompt, tries one or more legal login names and begins to try and guess passwords for these login names. Some UNIX systems store the encrypted version of every user’s password in a world readable file. In offline mode, the hacker use these encrypted files to guess the password.

The TRINOO Attack is of 3 steps :

A denial-of-service attack is an attempt to make the computer or internet resource unavailable to the intended users. ‘SMURF’ is a well- known type of DoS attack which is based on an attacker’s ability to spoof IP source address. Any system that uses IP address as a means of authentication can be compromised by an attack known as IP address spoofing. The attacker sends a request for return packet to the intermediate network’s broadcast address. From where, the request is automatically relayed to all the machines on the network. These machines then send reply back reply with a return packet. However, in the original attack packet, the attacker replaces his/her own true address with the address of the original victim. The victim machine hence is flooded with many such replies which in turn increase traffic at the victim’s site. Consequently, the target machine is forbid to perform any useful activity. 

DoS Attack

Putting it all together: When all the above attacks are put together, a full-fledged ambush is generated. One such attack is the distributed denial-of-service attack or DDoS. 

DDoS attacks render a host useless by flooding it with maliciously derived traffic from many attacking machines. These attacks have fetched a lot of media attention in the recent past when popular Internet websites like Yahoo! and eBay undergone temporary shutdown posterior to such an attack. Trinoo is software that creates a network of master and daemon machines to launch a DDoS attack. DDoS attacks may pose significant threats to machines connected to internet. This is due to the distributed nature of this attack.


The practice of hacking is not limited to computers alone but the cellular lines or mobile phones are target as well. Hackers worldwide have designed mobile hacking softwares called Bluetooth Hack Softwares. Once this software is installed in the target phone, the hacker can get full access to the remote mobile phone like access to phone book, messages, internet, making calls, restore factory settings, etc.

In the current scenario, at this stage talking about cyber attacks and cyber crime is totally inevitable. Any unlawful activity, wherein the computer is used as an instrument to perform or perpetuate the crime is registered under cyber crime. Ever since the inception of internet (initially known as ARPANET) in 1969, the use of computers to access internet has increased at a huge pace and hence had increased the sophistication of technical hackers over cyber crime. Initially, when internet came into force only a little provision was made to trace or track cyber attacks for internet security. Under the assumption of a benign user, no provision was made for the cryptographic authentication of the information contained in IP packets. But the current cyber threat environment is far beyond the original design parameters of the internet. Currently, the internet is subject to millions of cyber attacks and crimes worldwide. Some of the recent cyber attacks are listed below:
.   The first ever industrial cyber attack (on Siemens) was discovered in July, 2010 using a computer worm called Stuxnet. It is also found to be the first computer malware program ever which contains a PLC rootkit. A rootkit is a group of utilities that aids in setting up backdoors for the rooted machine for future access and abet to capture network’s internal information.
.   As reported by Google Inc, it became the victim of a cyber attack on its operations in China in 2010 that resulted in the theft of its intellectual property.
.   Recently in 2011, Sony reported an unauthorized theft on Sony’s Playstation Network which stole names, address and credit card data of around 77 million account holders on the network.
.   Other cyber crimes include credit card scandals, cyber squatting, phishing, child pornography, etc.

To keep a check on the increasing cyber crimes all over the world, Internet Service providers are employing various techniques to strengthen security in their networks. Several traceback techniques have been introduced to trace the approximate source of such attacks. Every technique has its own set of advantages and disadvantages. Backscatter traceback technique is primarily useful for spoofed attacks where the attackers use source addresses from the private IP address space. Centretrack techniques, Hop-by-Hop tracebrack, ICMP are some other techniques also used.
