COMPUTER WORLD:- Charles Barbage invented the machine which changed our lives for ever. ENAC was the first computer in 1950's with punching cards and then came the Vacuums tubes. The vacuum tubes are replaced with transistors, then with Integrated circuit IC. Finally we have a Microchip running with clock speeds of 1Mhz. Xeroxs was the one who invented the Graphic user interface for general computing made easy by seeing the computer screen graphically. In 1979 Steve Jobs introduced a computer called Apple I. From a company named Apple® computers. Then in 1984 Apple introduced Macintosh Operating System. Apple has changed the way people use the computer with the most easy to user Graphical User interface operating system with a mouse pointer to click and drag. Plug and play. Make text, graphics, Audio to integrate. As, Bill gate was a application developer for Macintosh OS, he was shown the secrets of the OS core for develop of the application from Microsoft.. Bill Gates well known as a cheater copied the Apple Macintosh OS and introduced a new operating system called Window 95. As IBM is the partner for Microsoft and giving the internet explorer for free it make Netscape navigator browser to Bankruptcy. Then in 1997 Apple® computers was into bankruptcy . With introduction of iMac® Computer Apple has regained its position and doing well then after. Bill Some how managed to copy the colorful Mac OS X Graphic user interface for his Microsoft XP. May be th Bill be a millionaire worth 40 million dollar but Steve Jobs is the most powerful among the Desktop computers. As, Apple computers made the computer very easy use. Otherwise remember those old days when u use to type commands for every task on DOS (Originally project named "Dirty Operating system" bought by BillGates from someone and improved it later), Unix command line interface.Still we all would have been using the same command line which is not that much of fun like the concept of Drag and Drop of Macintosh.

Lawrence J Ellison the founder and CEO of ORACLE® Cooperation hates bill gates.

People like STEVE JOBS of APPLE® computers, Andrew S Grove CEO of INTEL® Cooperation, Scott McNealy of SUN® microsystem, Richard Stall man UNIX GNU open source, Tomas J Watson Jr of IBM®, Ken Thompson and Dennis Ritchie the brain behind unix and C programming at BELL® Labs, E.F.Codds of RDBMS, Bill joy for BSD of Berkley co-founder of Sun microsystems and TCP/IP,Marc Andreson of Netscape® navigator, Linus Torvalds the creater of the operating system Linux, Seymour Cray the founder of CRAY® supercomputers.All these people have an significant effect on the computing world. The world's richest man's Operating system Window® is the most popularly used OS. The OS can be popular but that doesn't mean it a good operating system. Linux, and NextStep are the best GUI operating systems in the IBM compatible machines. With very good stability and true multi threading, Preemptive taskin. OS/2, Solaris, Linus , Macintosh X, jaguar, Panther all are based on UNIX os. Surely one day Bill will concentrate on Linux because Lunix is the worlds fastest developing OS as it is open source.

CRAY® SUPER COMPUTERS:This the one company with the super computer production.

SUN MICROSYSTEM: The pioneers in unix and inventors of "oak" language later called as JAVA. Its rival microsoft..!

DELL COMPUTERS: Originally started as a configuring as you order DELL at present is one of world most selling computer. Still Dell does assembling of the components and supply to the cooperate clients.

DVD and DVD-R: The DIGITAL VERSATILE DISC is the CD on steroids . big capacity of 4GB to 18 GB. Now with C3D technology using fluorine the CD can hold huge and heavy loads of 140 GB.u get Dvd writers so forget CD and switch o DVD's.

C3D: This a Cd that works on Florescent.As, Florescent has the property of refecting three different surfaces.This Disk can hold Capacities about 140 GB

Gigabit Ethernet : Forget about the 100/10 data transfer s wakeup u r in 2004..The gigabit ethernet with capacity to transfer data at very high speeds of 1000/100/10 mbps.

Wireless Lan card: U must be frustrated with the crumpled up wires of ur network. So, make yourself comfortable with the data card and access point capable of 102 mbps.

Blue Thooth: with this u can transfer the phone number from the mobile or PDA or watch to ur computer with out any wires.

Fire Wire: (Plug and Play) The fire wire 800 mbps u don't have to wait for long any more.It takes less the 10 secs to copy a CD to ur iPod or any other Mp3 player which supports firewire.

USB 2.0: (Plug and Play) Universal Serial Bus .With capacity of 480 mpbs. Half the time it takes in the fire wire.

Optic Mouse:No more cleaning ur mouse Ball.. (-; The optic mouse is more precise and good for drawing and graphic related works.

X-BOX: The X-Box from Microsoft is the ultimate gaming box.Good graphic card with great performance.

GeNevdaForce: This is pixel pumping device.. Great for games especially for heavy graphics gaming. U would love it if u r a gaming freak.

JEPG: ( Joint Expert Picture Group ).As, u all know that a picture needs lot of memory to maintain the best quality of a 32 bit color picture.As, BMP format(Microsoft), Tiff format, Pict format(Apple),Psd format (Adobe), Gif format, pixar format (Pixar animation), Targa format, Png format ,Raw format, Amiga format..!!! All the above formats occupy lot of memory space. Then the JPEG is a boon for the graphic professionals to reduce size of a images drastically by compression the image to 10% from 100%. This jpeg compression uses a special technique to compress the images by removing the unwanted color and the colors not visible to eye but generated by the computer and make it look as good as it was before

MPEG4: (Motion Picture Expert Group) You must have heard of Mp3. The layer 3 of motion picture. Depending the quality the layers are layer 1, layer 2, layer 3 , layer 4. The Mpeg4 is a new format which as the compression and has the DVD quality picture and CD sound quality.. This is the format which a new generation with very high quality video with occupying less memory.
