What is a computer short definition?
A computer is a device that can be programmed to carry out a set of arithmetic or logical operations. Computers can also be used to store, retrieve, and process data.
The first computers were created in the early 1800s. These devices were called mechanical calculators, and they could be used to solve mathematical problems. In 1876, Charles Babbage designed a machine called the Analytical Engine, which could be programmed to perform any calculation that could be done by hand. However, the machine was never completed.
In 1937, John Atanasoff and Clifford Berry developed the first electronic computer, called the Atanasoff-Berry Computer (ABC). However, this machine was not actually built until 1973.
In 1941, Konrad Zuse designed and built the first programmable computer.
In 1945, John von Neumann developed the first computer architecture, which is the blueprint for the design of a computer.
In 1948, the first transistor was invented, and this led to the development of the first microprocessor in 1971.
In 1971, the first microprocessor was created, and this led to the development of the first personal computer, which was the Apple I, in 1976.
Today, computers come in all shapes and sizes, and they are used for a variety of purposes.
What is a computer Wikipedia?
A computer is a device that can be programmed to carry out a sequence of arithmetic or logical operations. Computers are used in a wide range of applications, from personal computers to mainframe computers.
Personal computers, also known as desktops, are computers designed for individual use. They typically have a central processing unit, a keyboard, a mouse, and a monitor.
Desktop computers come in a wide range of shapes and sizes. They are usually built around a central processing unit, or CPU, that performs the basic arithmetic, logical, and input/output operations of the system. The CPU is usually attached to a motherboard, which contains the connectors for the system’s main memory, its video adapter, and other important devices.
The central processing unit is usually accompanied by a variety of I/O devices, including a keyboard, a mouse, and a monitor. The keyboard is used to enter data and commands into the system, the mouse is used to select objects on the screen, and the monitor displays the results of the computer’s operations.
Most desktop computers also include a hard disk drive, which is used to store data and programs. Some systems also include a floppy disk drive, which is used to read and write floppy disks. A CD-ROM drive is used to read CD-ROMs, and a DVD-ROM drive is used to read DVDs.
The basic structure of a desktop computer is shown in the following figure.
Desktop computers are typically designed for individual use, but they can also be used in networked configurations. In a networked configuration, several desktop computers are connected together to form a local area network, or LAN. The computers in a LAN can share resources, such as printers, files, and Internet access.
Most desktop computers use the Windows operating system from Microsoft. However, there are a number of other operating systems available, including the Mac OS from Apple, the Linux operating system, and the UNIX operating system.
Most desktop computers are powered by an AC adapter, which converts the 120-volt AC power from the wall outlet into the lower-voltage DC power that the computer requires. The computer itself includes a power supply that converts the DC power into the various voltages that the computer’s components require.
Desktop computers typically come with a number of preinstalled software applications, such as a web browser, a word processor, and a spreadsheet application. Users can also install their own applications, or software, on the computer.
Desktop computers are usually upgradable, which means that users can add new components, such as a new video adapter or a larger hard disk, to the system.
Most desktop computers are also expandable, which means that users can add new devices, such as a scanner or a printer, to the system.
The following table provides a summary of some of the most important features of desktop computers.

What is the definition of computer with example?
A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically.
The capability of computers to follow a sequence of operations, called a program, make them very useful in tasks such as data processing, accounting, record keeping, and telecommunications.
Computers can be classified in many ways, but one of the most basic ways is by the number of bits they can process at one time. A bit is a unit of information that can have one of two values, 0 or 1. A computer that can process eight bits at a time is called an octal computer, and one that can process 16 bits is called a hexadecimal computer.
Computers are also classified by their general-purpose or special-purpose design. General-purpose computers can be used for a variety of tasks, whereas special-purpose computers are designed for a specific task, such as controlling a manufacturing process.
Some early computers were designed to perform a single task, such as the Atanasoff-Berry Computer (ABC), which was designed to solve systems of linear equations. However, the first general-purpose computers, such as the ENIAC, were designed in the 1940s.
Computers are now an essential part of everyday life. They are used in a wide range of applications, including data processing, telecommunications, manufacturing, and transportation.
What are the 5 definition of computer?
A computer is a machine that can be programmed to carry out a set of instructions.
In its most basic form, a computer consists of a processor, memory, and input/output (I/O) devices. The processor carries out the instructions that are stored in memory, and the I/O devices allow the computer to communicate with the outside world.
Computers can be divided into four main categories: desktop, laptop, tablet, and smartphone.
Desktop computers are typically larger and have more features than laptops. They are typically used for tasks such as word processing, gaming, and web browsing.
Laptops are smaller than desktops and are designed for portability. They are typically used for tasks such as online banking, email, and web browsing.
Tablets are smaller than laptops and are designed for portability. They are typically used for tasks such as watching videos, playing games, and reading books.
Smartphones are small, portable devices that are designed for use with one hand. They are typically used for tasks such as making phone calls, sending text messages, and accessing the internet.
What is computer definition and its types?
A computer is a device that can be programmed to carry out a set of instructions.
There are three main types of computer – desktop, laptop and tablet. Desktop computers are typically larger and have more powerful processors than laptops. Tablets are smaller than laptops and typically have weaker processors, but they are more portable.
Computers are made up of hardware and software. Hardware consists of the physical components of the computer, such as the processor, RAM, and hard drive. Software consists of the programs that run on the computer, such as the operating system and applications.
Computers are classified by their level of performance, which is measured in terms of the number of instructions they can carry out per second, or hertz. The most common classification is low-end, mid-range and high-end. Low-end computers are typically used for basic tasks such as browsing the internet, checking email and word processing. Mid-range computers are powerful enough to handle more advanced tasks such as photo and video editing, and gaming. High-end computers are the most powerful and are used for tasks such as data analysis and scientific modelling.
The price of computers also varies depending on their performance. Low-end computers can be purchased for as little as $200, while high-end computers can cost $3000 or more.
