What is a computer made of?

Read in a minute. Principles of Computer Composition.

A computer is composed of two parts: a hardware system and a software system.

Computer hardware is an important part of a computer, which contains five important components: combinator, controller, memory, input device, and output device.

Computer software systems are usually divided into two categories: system software and application software. System software generally includes operating systems, language processing programs, database systems, and network management systems. Application software is generally divided into two categories, one is practical software developed for specific needs, and the other is a tool software provided for the convenience of users to use computers.

A computer consists of two parts: a hardware system and a software system.

Mainly: motherboards, power supplies, cups, hard disks, optical drives, memory modules, graphics cards, network cards, sound cards, modems, floppy drives (old computers), radiators, monitors, keyboards, mice, etc.

The hardware of the computer

1. Host. 1) Power supply: Convert 220V AC to 5V, 12V, DC used in the computer, and the power supply performance directly affects the stability of other equipment.

2) Motherboard: The various parts of the computer are closely connected together, and each part transmits data through the motherboard.

3) CPU: The control computer that performs logical operations, data processing, and input and output completes various operations automatically and coordinatedly.

4) Memory: Memory, also known as internal memory, belongs to electronic storage devices, it is composed of circuit boards and chips, characterized by small size, fast speed, electricity can be stored, no electricity empty, data can be stored when the computer is turned on, and all data in it will be automatically emptied after shutdown.

5) Hard disk: external memory, made of metal magnetic sheet, magnetic sheet has memory function, so the data stored on the magnetic sheet, whether it is turned on or off, will not be lost.

7) Graphics card: The graphics card works with the display to output graphics and text, and its role is to convert the signal sent by the CPU into the analog signal recognized by the display, and transmit it to the display for display.

8) Modem: A modem is one of the indispensable devices when accessing the internet through a ** line. Its function is to convert the digital signal processed by the computer into an analog signal of the first line.

9) Network card: The role of the network card is to act as a bridge between the computer and the network cable, and it is an important device used to establish Internet access.

10) Floppy drive: The floppy drive is used to read data from a floppy disk. Floppy disks are read-write external storage devices.

11) Optical drive: The optical drive is used to read the data in the disc. The disc is a read-only external storage device.

2. Display: It is an output device, which can display the results of computer processing.

3. Keyboard: The keyboard is an input device.

4. Mouse.

c Memory.

d Output device.

e Controller.

The host consists of a motherboard, power supply, cup, memory module, graphics card, hard disk, optical drive, radiator, floppy drive (old computer), monitor, keyboard, and mouse.

It is composed of hardware system and software system: the hardware system is divided into host system and external equipment. The host system is divided into processors (CPUs), memory, and motherboards.

External devices are divided into external storage devices, input devices, and output devices. The soft drop system is divided into basic input and output system (BIOS), system software, and application software.

It is composed of five parts: combinator, controller, memory, input device, and output device, and the input and output devices are usually referred to as IO devices (input and output devices).

The composition of computers and computer hardware, as well as the classification of computer software.

Software Hardware Input Device Output Device.

Computer composition refers to the logical implementation of the system structure, including the composition and logic design of the data flow and control flow in the machine. It is mainly divided into five parts: controller, combinator, memory, input device, and output device.

The aspects of computer composition design to determine the key clarity should include:

2) The setting of special parts: whether to set up special components such as multiplication and division, floating-point arithmetic, character processing, address arithmetic, etc., the number of settings is related to the speed to be achieved by the machine, the frequency of use of special components, etc.

3) The degree of sharing of parts by various operations: the degree of time-sharing is high, although the speed is limited, but it is cheap. Setting up parts to multi-minding leads reduces the degree of sharing, and the speed can be increased due to the increased parallelism of operations, but it will also increase.

4) Parallelism of functional components: whether to use sequential serialization, or to use overlapping, flow or distributed control and processing.

5) The composition of the control mechanism: whether it is hard-connected or micro-program control, whether it is single-machine processing or multi-machine or functional distribution processing.

6) Buffering and queuing technology: how to set up buffers between components and how large capacity of buffers are set to coordinate their speed differences; Use random, first-in-first-out, first-in-last-out, priority, or round-robin to arrange the order in which events are processed.

The components of a computer: combinators, controllers, surviving reservoirs, input devices, and output devices.

Computer, commonly known as computer, is a modern electronic computer machine used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive limb return data automatically and at high speed. A computer that consists of a hardware system and a software system without any software installed is called bare metal.

Computers

Due to the development of integration technology, the integration of semiconductor chips is higher, each chip can accommodate tens of thousands or even millions of transistors, and the combinator and controller can be concentrated on a chip, resulting in the emergence of microprocessors, and can be assembled into microcomputers with microprocessors and large-scale, ultra-large-scale integrated circuits, which is what we often call microcomputers or PCs.

The microcomputer is small, cheap, and easy to use, but its power and computing speed have reached or even surpassed the mainframe computers of the past. On the other hand, various logic chips made by large-scale, ultra-large-scale integrated circuits have been made into supercomputers that are not very large in size, but can be operated at a speed of 100 million or even billions of times.
