Computers use a variety of data storage devices. The most common data storage device is the hard disk. Other data storage devices include the CD-ROM, the DVD, the flash drive, and the cloud.
How does a computer work work?
A computer is a machine that can be programmed to carry out a sequence of arithmetic or logical operations. Computer processors are the electronic circuitry that carry out the instructions of a computer program.
The history of computing hardware can be divided into five generations: the first generation of computers were mechanical, the second used vacuum tubes, the third used transistors, the fourth used microprocessors, and the fifth uses semiconductor integrated circuits.
Computers are made of electronic components, circuits, and logic gates. Electronic components are made of metals, semiconductors, and insulators. Circuits are made of wires and components, and logic gates are made of transistors.
The basic operation of a computer is to store, retrieve, and execute instructions. Instructions are stored in the computer’s memory, which is organized into registers and memory banks. The registers are small, fast, and located on the computer’s processor. The memory banks are large and slow, and they are located outside of the processor.
The processor retrieves instructions from memory and executes them. It does this by reading the instruction, decoding it, and executing the instruction. The instruction is usually a machine code instruction, which is a code that is specific to the processor.
The computer’s memory is organized into bytes. A byte is a unit of information that consists of eight bits. The bits are the basic unit of information in a computer. They are either one or zero.
A computer’s processor can execute one instruction per cycle. A cycle is the time it takes for the processor to read an instruction, decode it, and execute it. The speed of the processor is measured in cycles per second, or hertz (Hz).
Most computers have a clock that runs at a frequency of millions of cycles per second. This clock is used to synchronize the different parts of the computer. The clock is also used to time-stamp events, so that they can be ordered and processed.
The basic components of a computer are the processor, the memory, and the input/output (I/O) devices. The processor is the brains of the computer, and the memory is its short-term storage. The I/O devices are used to interact with the user and to transfer data to and from the computer.
The processor is made up of the arithmetic logic unit (ALU), the control unit (CU), and the registers. The ALU is used to perform arithmetic and logical operations, and the CU is used to control the sequence of operations. The registers are used to store the operands and the results of the operations.
The processor is connected to the memory by a set of wires called the data bus. The data bus is used to transfer data between the processor and the memory. The processor is also connected to the I/O devices by a set of wires called the address bus. The address bus is used to transfer addresses between the processor and the I/O devices.
The computer’s memory is organized into a number of memory banks. A memory bank is a group of bytes that are located at a specific address. The processor can access a memory bank by using the address that is on the address bus.
The memory is also organized into a number of registers. A register is a group of bytes that are located at a specific address. The processor can access a register by using the register’s name.
The input/output devices are usually connected to the processor by a set of wires called the control bus. The control bus is used to transfer control signals between the processor and the I/O devices.
How does a computer work in answer?
A computer is a machine that can store, process and transmit information. The first computers were created in the early 1800s and were called mechanical calculators. 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 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.
The first computers were large, expensive and used vacuum tubes.
In the 1950s, transistor-based computers were developed. These were smaller, faster and more reliable than the previous generation of computers.
In the 1960s, integrated circuit (IC) computers were developed. These were even smaller and faster than transistor-based computers.
In the 1970s, microprocessor-based computers were developed. These were even smaller and faster than IC computers.
In the 1980s, personal computer (PC) were developed. These were small and inexpensive and could be used by individuals.
In the 1990s, the World Wide Web was developed and the use of computers exploded.
Today, most people have personal computers that they use for work, school, entertainment and communication.
How a computer works step by step?
A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically.
The three basic operations that a computer can perform are input, processing, and output.
Input is the process of entering information into the computer.
Processing is the process of performing operations on the data, such as arithmetic or logical operations.
Output is the process of sending the results of the processing operations to the computer output devices, such as the screen, printer, or speakers.
How does computer work explain with diagram?
A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically. Computing has become an essential part of everyday life. Modern society relies heavily on computers and computer-based systems.
A computer system consists of hardware and software. The hardware includes the physical components of the system such as the Central Processing Unit (CPU), memory, input/output devices, and storage. The software includes the programs that run on the system and control the operation of the hardware.
The CPU is the heart of the computer system. The CPU carries out the instructions in the software. It is a single chip that contains the circuitry that performs the basic operations of arithmetic, logic, and control.
The memory is a set of electronic components that store data and programs. The memory is divided into a number of areas called registers, buffers, and cache. The registers are small areas that hold a single value. The buffers are larger areas that can hold a number of values. The cache is the largest area and is used to store the most frequently used values.
The input/output devices are used to communicate with the user and other devices. The most common input device is the keyboard. Other input devices include the mouse, trackball, touch pad, joystick, and scanner. The most common output device is the monitor. Other output devices include the printer, speakers, and headphones.
The storage is used to store data and programs. The most common type of storage is the hard drive. Other types of storage include the floppy disk, CD-ROM, and DVD-ROM.
