Computer hardware is a physical part of a computer that executes within the hardware. It is unlike computer software or data that can be frequently changed, modified or erased on a computer. Computer hardware is not frequently changed and so is stored in hardware devices such as read only memory (ROM) where it is not readily changed.
Most computer hardware is embedded and so is not visible to normal users. Below are the different types of hardware’s found in a computer.
Motherboard: It is the central or primary circuit board making up a complex electronic system such as a computer. A motherboard is also known as a main board, logic board or system board.
Central processingUnit: A CPU is the main component of a digital computer that interprets instructions and process data in computer programs.
Random Access Memory:RAM allows the stored data to be accessed in any order. RAM is considered as the main memory of the computer where the working area is used for displaying and manipulating data.
Basic Input Output System: BIOS prepares the software programs to load, execute and control the computer.
Computer Bus: It is used to transfer data or power between computer components inside a computer or between computers.
CD-ROM drive: It contains data accessible by a computer
Floppy disk: It is a data storage device. Hard Disk: It is a non-volatile data storage system that stores data on a magnetic surface layered unto hard disk platters.

Help answer the question about Computer software
What do I look under if I need someone to make some computer software for a program I came up with?I have a great idea for some business software, I don't know where to start, who to ask, or anything, I would have to have it already made to be able to sell it. Would someone who designs software, be called a computer programmer? I don't have any idea! Thanks for any help!

I like AOL Active Virus Shield. Don't let the name AOL fool you. Active Virus Shield is made by Kaspersky which is one of top-rated anti-virus vendors in the world.
In recent tests, the most popular free anti-virus, AVG, was only able to detect about 82% of a very large sample of viruses. On the other hand, Active Virus Shield was able to detect better than 99% in the same test.
Full test chart is here:
http://www.virus.gr/english/fullxml/default.asp?id=82&mnu=82
Active Virus Shield has excellent virus detection rates and is extremely light on using your computer resources. (6mb ram)
Active Virus Shield detects and removes spyware, also.
And it updates up to 15 times a day with new virus definitions, 7 days a week.
Good stuff, free for everyone from:

@djb1a2k3 you shouldt
you should learn hoe to do them

You shouldn't need a special software for that. If you using windows, you should just be able to right click the file folder, go to "send to" and select your cd/dvd drive. A bubble should pop up saying you have files to burn. Click it and it should take you to a folder showing all your pictures and somewhere you should be able to select burn to disc.

hi,
First of all let me tell you one thing that before microsoft there was very little scope for personal computers and softwares related to those computers. Still there were some softwares and software building programming languages. FORTRAN or formula translation, the first high level programming language, was invented by John Backus for IBM, in 1954, and released commercially, in 1957. It is still used today for programming scientific and mathematical applications. Fortran began as a digital code interpreter for the IBM 701 and was originally named Speedcoding. John Backus wanted a programming language closer to human language, which is the definition of a high level language.
At that time the softwares available were Aldus Pagemaker, Trillian, Wordstar, Computer Chess, VisiCalc Spreadsheet. WordStar – The First Word Processor Released in 1979 by Micropro International, WordStar was the first commercially successful word processing software program produced for microcomputers and the best selling software program of the early eighties. first desktop publishing program was created by Paul Brainard and a company called Aldus, the program called "Aldus Pagemaker 1.0" was released in July, 1985 for the "Macintosh" and in December, 1986, for the "IBM". If you go with the history of operating system than previously there was nothing except UNIX.

To become a software engineer its not a must that u should take computer science in ur 11th n 12th
u should be good at mathematics ,physics and chemistry in ur entrance examination 'TNPCEE' Tamil Nadu Professional Courses Entrance Examination IF IN TAMILNADU
n u can also take AIEEE All India Engineering Entrance Examination which helps u enter in IIT Indian Institute of Technology……
u must prepare well for this exam……
Questions will be only from ur hsc books in TNPCEE and for AIEEE it'll be very easy if u r a CBSE STUDENT
All The Best For Ur Bright Future………

For Audio: Audacity, hands down. 100% free, 100% awesome
For Video: Open Movie Editor, I have also heard of Kaltura, but I haven't tried it out. Other than that, you can't work with video too much without really expensive software like adobe, and there is a bit of a learning curve to boot.
