what is a computer?

Question

full details about computer..

Answer 1

A computer is a machine for manipulating data according to a list of instructions known as a program.



Computers are extremely versatile. In fact, they are universal information-processing machines. According to the Church–Turing thesis, a computer with a certain minimum threshold capability is in principle capable of performing the tasks of any other computer. Therefore, computers with capabilities ranging from those of a personal digital assistant to a supercomputer may all perform the same tasks, as long as time and memory capacity are not considerations. Therefore, the same computer designs may be adapted for tasks ranging from processing company payrolls to controlling unmanned spaceflights. Due to technological advancement, modern electronic computers are exponentially more capable than those of preceding generations (a phenomenon partially described by Moore's Law).



Computers take numerous physical forms. Early electronic computers were the size of a large room, while entire modern embedded computers may be smaller than a deck of playing cards. Even today, enormous computing facilities still exist for specialized scientific computation and for the transaction processing requirements of large organizations. Smaller computers designed for individual use are called personal computers. Along with its portable equivalent, the laptop computer, the personal computer is the ubiquitous information processing and communication tool, and is usually what is meant by "a computer". However, the most common form of computer in use today is the embedded computer. Embedded computers are usually relatively simple and physically small computers used to control another device. They may control machines from fighter aircraft to industrial robots to digital cameras.

Answer 2

Computer is Electronic Machine. Every where is Used the Computer. Computer is Electronic Device. Many Three Type of computer.

1. Mainframe computer

2. Mini computer

3. Micro computer

Answer 3

A computer is a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program or sequence of instructions on how the data is to be processed. Complex computers also include the means for storing data (including the program, which is also a form of data) for some necessary duration. A program may be invariable and built into the computer (and called logic circuitry as it is on microprocessors) or different programs may be provided to the computer (loaded into its storage and then started by an administrator or user). Today's computers have both kinds of programming.

Answer 4

The personal computer (PC) defines a computer designed for general use by a single person. While a Mac is a PC, most people relate the term with systems that run the Windows operating system. PCs were first known as microcomputers because they were a complete computer but built on a smaller scale than the huge systems in use by most businesses.

Answer 5

A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.



Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.



Mechanical analog computers started appearing in the first century and were later used in the medieval era for astronomical calculations. In World War II, mechanical analog computers were used for specialized military applications such as calculating torpedo aiming. During this time the first electronic digital computers were developed. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1]



Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Computers are small enough to fit into mobile devices, and mobile computers can be powered by small batteries. Personal computers in their various forms are icons of the Information Age and are generally considered as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from electronic toys to industrial robots are the most numerous.

Answer 7

A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. You probably already know that you can use a computer to type documents, send email, play games, and browse the Web. You can also use it to edit or create spreadsheets, presentations, and even videos.

Answer 8

Your working personal computer scientist is a scientist having acquired knowledge of laptop science, the study of your theoretical foundations of information and facts and computation and its application.



Computer scientists typically improve the theoretical side of laptops, as opposed to a hardware side that computer engineers mainly center on (although there is definitely overlap). Although computer scientists might also focus their work plus research on specific areas (just like algorithm and data shape development and design, program engineering, information theory, collection theory, computational complexity way of thinking, numerical analysis, programming expressions theory, computer graphics, plus computer vision), their foundation is a theoretical study of computing that these other fields get at. [1]



A primary goal of computer scientists is a development (and acceptance) of models—often math in nature—for estimating a properties of computer-based models (processors, programs, pc's interaction with people, computers reaching other computers, etc. )#) which has an overarching objective of locating designs that admit to get improved performance (speedier, better, cheaper, etc. )#).

Answer 9

A computer generally means a programmable machine. The two principal characteristics of a computer are: it responds to a specific set of instructions in a well-defined manner and it can execute a prerecorded list of instructions (a program).

Answer 10

Computers are machines that perform tasks or calculations according to a set of instructions, or programs. The first fully electronic computers, introduced in the 1940s, were huge machines that required teams of people to operate. Compared to those early machines, today's computers are amazing. Not only are they thousands of times faster, they can fit on your desk, in your lap, or even in your pocket.

Computers work through an interaction of hardware and software. Hardware refers to the parts of a computer that you can see and touch, including the case and everything inside it. The most important piece of hardware is a tiny rectangular chip inside your computer called the central processing unit (CPU), or microprocessor. It's the "brain" of your computer—the part that translates instructions and performs calculations. Hardware items such as your monitor, keyboard, mouse, printer, and other items are often called hardware devices, or devices.

Software refers to the instructions, or programs, that tell the hardware what to do. A word processing program that you can use to write letters on your computer is a type of software. The operating system (OS) is software that manages your computer and the devices connected to it. Two well-known operating systems are Windows and Macintosh operating system. Your computer uses the Windows operating system.

Answer 23

A computer is noting more than bunch of on off switch. These are called circuits. The hardware or actual thing that sits on your desk has three main features: The CPU central processing unit. This main collection of circuits. It tell you how many electric messages can be sent and how fast they will be sent. The next part of hardware is memory. I don't filly understand this but two types of memory RAM radon Access Memory and storage there is better term. The last aspect of hardware is how you put these on off signal into and out of your computer: Main way is by keyboard or you can put it in off Internet downloads or by CD into CD player. The number of ports and USB Th Unniveral Service Buses tell you how many ways you can put on off messages in and out. eamples, in keyboard, cd player, tapes internet. out monitior, printer, speakers

Software are the traffic cops that tell what on off messeages do. The basic traffic cops are built into CPU. This is part of RAM I don't fully understand, but you need on off messages to tell on off meaasges what to do. For much better explination see if you can get Bill Gates book the Road Ahead in the library.
