HOW BILL GATES EMERGED ON GLOBAL FRONT

William Henry Gates III was born on October 28th, 1955 in Seattle, Washington. Popularly known as Bill Gates, he heads the biggest software company in the world and was voted the world's richest man by Forbes for 12th consecutive years.

Bill Gates steered Microsoft to control more than 90% of the client operating system market and be worth more than $300 billion by market capitalization, as of October 2005. Since going public at $21/share on March 13th, 1986, Microsoft stocks has split 9 times and would be worth a staggering $8064 today. If you had invested $10,000 in Microsoft stocks in 1986, your stocks would be worth $3.8 million today ...or up to $7 million before the tech bubble burst in 2000.

Gates makes $155,000 an hour based on his net worth today.

During his schooling in 1967 Bill Gates met Paul Allen. Bill Gates and Paul Allen reported bugs in exchange computer time and formed Traf-O-Data to develop hardware/software to record highway traffic. After graduation in Pre-Law in 1973 he and Paul formed Micro - Soft in 1974. They further wrote the first computer language called BASIC and licensed it to MITS. Bill writes software routines for BASIC on the Altair to use diskettes for storage.

In 1977 Bill Gates and Paul Allen officially registered a partnership, and Micro-soft became Microsoft. Microsoft proposed to be in-charge of IBM's entire software development and convert DOS for IBM's PC in 1980. Microsoft bought all the rights to SCP's (Seattle Computer Products') DOS and renamed it MS-DOS. IBM introduced its first desktop, Datamaster, which runs on the 16-bit 8086 CPU and Microsoft's MS-DOS. In 1983 Bill Gates announced Microsoft 1.0 and after 2 years released it for the public. Bill Gates became a billionaire at 31 years old - the youngest person to do so.

OVERVIEW OF DIFFERENT OPERATING SYSTEMS:

MS-DOS

INTRODUCTION

DOS stands for Disk Operating System. There are many versions of DOS available, but Windows 95/98/NT machines use MS-DOS*. DOS is a command line environment that sits beneath Windows systems. Before Windows, there was only DOS. With DOS a user can do most of the functions that one would do with Windows; make directories, edit files, run programs, compile code, print, get on-line. In fact, most of the operations of Windows are just graphical representations of DOS functions. Some earlier versions use different commands and some new versions have deprecated the old commands. The commands described here are fairly common to all and are still current in recent versions of MS-DOS. Different versions of Dos are given below periodically:

MS-DOS 1.0 was released in Aug, 1981.
MS-DOS 1.25 was released in Aug, 1982.
MS-DOS 2.0 was released in Mar, 1983.
Microsoft introduces MS-DOS 3.0 for the IBM PC AT and MS-DOS 3.1 for networks in 1984.
MS-DOS 3.2 was released in Apr, 1986.
MS-DOS 3.3 was released in Apr, 1987.
MS-DOS 4.0 was released in Jul, 1988.

Windows 3.1 allowed users to utilize several features previously not available in MS-DOS. Some of these new features were the use of a mouse which allowed the user to navigate and manipulate data on the computer with one hand simply and easily and now did not have to memorize MS-DOS commands. In addition to the mouse, Windows now allowed the user to multitask, meaning the user could now run multiple applications at once without having to close out of each program before running another. Windows along with other GUI operating systems are one of the many reasons computers have become easier and more widely used.

Windows NT contains advanced security features, advanced network support, full 32-bit operating system, advanced multitasking, user administration and much more. While NT is a very advanced operating system, it does lack the support of drivers, features, and gaming support when compared to Windows 95 / Windows 98 and is why, even today, Windows NT is still used primarily by businesses and technical users.
