A simple question .... What do you mean by a computer? (answer in 400 - 500 words)
hrutikps99p8efmc:
In computing, a benchmark is the act of running a computerprogram, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it.

bro ! ur simple answer ☺
A computer is a machine (mostly electronic) that is able to take information (input), and process it to make new information (output).
Calculating machines are old in the history of technology. Early examples are the astrolabeand the abacus. Today a computer is a programmable machine. The two principal characteristics of a computer are: It responds to a specific instruction set in a well-defined manner and it can execute a prerecorded list of instructions (a program). There are four main processing steps in a computer: inputting, storage, outputting and processing.
Modern computers are very different from early computers. They can do billions of calculations per second. Most people have used a personal computer in their home or at work. Computers do many different jobs where automation is useful. Some examples are controlling traffic lights, vehiclecomputers, security systems, washing machines and digital televisions.
A computer user can control it by a user interface. Input devices include keyboard, mouse, buttons, and touch screens. Some very sophisticated computers can also be controlled with voice commands or hand gestures or even brain signals through electrodes implanted in the brain or along nerves.
Computers can be designed to do almost anything with information. Computers are used to control large and small machines which in the past were controlled by humans. They are also in homes, where they are used for things such as listening to music, reading the news and writing.
Modern computers are electronic computer hardware. They do mathematical arithmeticvery quickly but computers do not really "think". They only follow the instructions in their software programs. The software uses the hardware when the user gives it instructions, and gives useful output.
Computer programs are designed or written by computer programmers. A few programmers write programs in the computer's own language called machine code. Most programs are written using a programming language like C++, Java, and Fortran. These programming languages are more like the language with which one talks and writes every day. The compiler translates the user's instructions into binary code (machine code) that the computer will understand and do what is needed........

Wow that's nice ....!!
But it was not simple as i think you could have written it more simply manner ... but it seems to me glad that i have just ask in simple and you answered it in a complicated manner with those kind of examples of OOP !! Great job !!
thank u bro,,, u asked me simple question ,,so i gave simple answer..
yup that was cool !!

Hi friend!!
Computer is an electronic device that executes a sequence of instructions in a defined manner. Computer operations include numerical computations ,data manipulation ,input and output. An organized set of instructions,written in any computer language that perform the specific task is called a PROGRAM.It is through input devices that the computer accepts input processes them and then performs arithmetic
and logical operations on it in accordance with a program and produces information as output through the output devices.
Data is a collection of unorganised facts which may include letters of the alphabet,digits,graphics and sound.Data is always converted into binary form for the use by the computer.
Computer processes data to produce information.Information may be defined as the processed data.Information adds to knowledge and helps in decision making.All the data and the information can be stored inside the computer in it's memory. READ ONLY MEMORY(ROM),RANDOM ACCESS MEMORY(RAM) chips act as a permanent and temporary electronic memories for storing data and information respectively.
A typical computer system consists of a main unit containing central processor,together with memory chips and storage devices( magnetic disks), input devices (keyboard,mouse,lightpen, etc) and output devices (monitor,printer ,etc).
Computer programs are usually stored on disks and transferred to machine's RAM when required.
The study of computers is called computer science. Computer theory delas with organizational,legal and historical aspects of computers. Data is always converted into binary form for the use by the computer.Computer theory includes computional methods and numerical analysis.
Simply, computer consists of a monitor,keyboard,CPU (Central processing unit),mouse etc
I hope this will help u ;)
