A computer is a machine that can store, retrieve, and process data. They come in a variety of shapes and sizes, from desktop towers to laptop computers to handheld devices like smartphones and tablets.
The heart of a computer is its central processing unit, or CPU. This is the component that carries out the instructions you give it, whether it’s retrieving a file from the hard drive or loading a web page.
In order to carry out these instructions, the CPU needs a way to store data. This is traditionally done using a spinning disk called a hard drive. However, with the advent of cloud computing, many computers are now storing data on remote servers rather than on-board devices.
Other important computer components include the random access memory, or RAM, which is used to store data that is currently being used by the CPU, and the graphics processing unit, or GPU, which is responsible for rendering images on the screen.
All of these components work together to create what is known as the system unit, or motherboard. This is the main circuit board that everything else is attached to, and it’s responsible for communicating with other devices, such as the keyboard, mouse, and display.
Computers use a variety of input and output devices to communicate with the user. The most common input device is the keyboard, followed by the mouse. Other common input devices include the touchpad, trackball, and joystick.
Output devices include the display, which can be either a computer monitor or a television, and the printer, which prints documents or images that have been stored on the computer.
There are also a number of auxiliary devices that can be attached to a computer, such as the webcam, which allows you to take pictures and videos, and the microphone, which allows you to record audio.
So, what defines a computer? In its most basic form, a computer is a machine that can store, retrieve, and process data. It’s made up of a variety of components that work together to allow you to interact with it.
What qualifies a computer?
When most people think of a computer, they think of a desktop or laptop. However, there are many different types of computers, from mainframes and minicomputers to smartphones and tablets. So what exactly qualifies as a computer?
The most basic requirement for a computer is that it can store and process information. This can be done through electronic circuitry, as in the case of traditional computers, or with software, as in the case of smartphones and tablets.
In addition to being able to store and process information, a computer must be able to interact with a user. This can be done through a variety of input devices, such as a keyboard, mouse, or touchscreen.
Finally, a computer must be able to output information. This can be done through a monitor, printer, or other device.
So, while not all devices that store and process information are computers, most devices that meet the above criteria qualify as computers.
What are the 5 definition of computer?
In computing, a computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically. The ability to store and retrieve arbitrary amounts of data is also a significant feature. When referring to the capabilities and features of a computer, the term “programming” is often used interchangeably with “software”, although software technically refers to the instructions a computer carries out, while programming refers to the process of designing and creating that software.
The first electronic computers were developed in the early 1940s, and they differed significantly from the modern computers that are in use today. The first computers were large, expensive, and used vacuum tubes. They were used for military applications, scientific research, and for creating the first digital computers.
Since the early days of computing, the definition of a computer has evolved to include smaller, more affordable, and more energy-efficient devices. In addition, the definition has also been expanded to include devices that are not traditionally thought of as computers, such as smart phones and tablets.
The following are five common definitions of a computer:
1. A device that can be instructed to carry out sequences of arithmetic or logical operations automatically is known as a computer.
2. A computer is a device that can store and retrieve arbitrary amounts of data.
3. A computer is a device that can interface with the outside world.
4. A computer is a device that is capable of running a computer program.
5. A computer is a device that can be used for general-purpose computing.
What is computer define with example?
Computer is an electronic device that is used to store and process data. It is a machine that can be programmed to perform a wide variety of tasks.
The first computers were created in the early 1800s. They were called mechanical calculators, and they could only be used by mathematicians and scientists. 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 built.
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 1946, ENIAC, the first electronic general-purpose computer, was created.
In 1948, John von Neumann developed the architecture for a computer that is still used today.
The first computers were large, expensive, and used vacuum tubes.
Today, computers are smaller, cheaper, and use transistors.
Computers can be used for a variety of tasks, including:
-Storing and processing data
-Communicating with other computers
What are the 3 types of computer?
There are three types of computer: personal computers, mainframes, and supercomputers.
Personal computers are the most common type of computer. They are small and portable, and they typically use a Windows or Mac operating system.
Mainframes are larger than personal computers and are used by businesses and governments. They typically use a Unix or Linux operating system.
Supercomputers are the most powerful type of computer. They are used for scientific and military purposes. They typically use a Unix or Linux operating system.
Why computer is called computer?
The word “computer” is derived from the Latin word “computare”, which means “to count”. In the early days of computing, people used computers to perform mathematical calculations.
What are the 7 types of computers?
There are seven types of computers that are in use today:
1. Desktop computers
4. Tablet PCs
Desktop computers are the traditional type of computer that most people are familiar with. They typically have a large monitor, a keyboard, and a mouse. Desktop computers are typically used for tasks such as word processing, internet browsing, and gaming.
