A computer is a complex machine that can perform many calculations at extraordinary speeds. Moreover, its processing power is usually a comparison to the processing power of the human brain.
There is no doubt that the human intel capabilities are the winner of this competition, but the power of computers cannot be underestimated.
Similarly, inspired by the human brain, this complex machine consists primarily of processing units, arithmetic/logic units, computer storage, input and output devices, and their peripherals. These “parts” make up the “whole” system.
Processors, computer memory, input, and output devices are vital parts of a computer. Each of these parts is responsible for a particular feature set.
So, below are the main parts of the computer.
The CPU or Central Processing Unit
The main body inside the computer is the CPU. This unit is responsible for all events on the computer. It controls all internal and external devices. And performs “mathematical and logical operations.
Besides, the operations are by the microprocessor which is commonly known as the “brain” of the processor.
The instruction set is the “hard-wire” part of the CPU and it is responsible for setting the CPU’s machine language.
So, the more complex the instruction set, the slower the CPU will run. And the difference between processors depends on the instruction set.
Similarly, the control unit and the arithmetic logic calculation unit of the computer system are the central processing unit (CPU).
This component is the actual brain of any computer system. In the human body, the brain makes all significant decisions, and the rest of the mind moves according to the direction of the given brain.
Similarly, in a computer, meaningful calculations and comparisons are the work of the CPU.
Motherboard
Computer motherboards include slots where microprocessors go in. Memory slots, chips that act as interfaces between the CPU bus.
And peripheral buses (buses connect all internal components of the computer), non-volatile memory chips, and systems. Includes firmware.
Furthermore, you can use the clock generator to synchronize various details of your system. Some motherboards have logic and connectors that support input devices, such as PS / 2 connectors for mice and keyboards.
The SSD hard drive
A hard disk is actually a critical part of a computer disk drive that stores data. And gives computer users quick access to large amounts of data.
Similarly, a hard disk consists of electromagnetically charged surfaces or magnetic disks that record data in concentric circles called tracks.
This is a non-volatile storage device that stores digitally encoded data.
And Used to read and write data on the hard disk, like a phonograph recorder player. Desktop hard drives can typically store 120GB to 2TB of data. Laptop hard drives are small and have low data storage capacity.
Ram Memory
This refers to the computer component that holds digital data. It is the core of the computer and forms the basic computer model together with the CPU.
The drum and delay line used as the primary storage device in early computers. Is now small silicon chips that can effectively store large amounts of data.
Random-access memory, usually called RAM, is a small, lightweight, and volatile computer memory. You can save data temporarily. A program located on a computer processor is the fastest type of computer storage.
The most frequent information is sent to the computer’s processor cache to improve performance.
Computers need non-volatile main memory to read large programs. This non-volatile memory is ROM or read-only memory. There is also a startup program to start the computer.
Besides, secondary storage media (such as flash memory, tape, punch cards, zip drives) and tertiary storage media (such as tape libraries) are also part of computer memory.
Power supply
As the name suggests, the power supply supplies all other components of the machine.
It usually connects to the motherboard to power other features. The power supply also connects to the built-in battery (for laptop computers) or power outlet (for desktop computers).
Computer case
Computer cases are metal and plastic cases that contain key computer components such as the motherboard, central processing unit (CPU), and power supply.
Similarly, they actually come in many varieties of shapes and sizes. The desktop case is flat on the table, and the monitor is usually on the table.
The tower case is high and sits next to the monitor or on the floor. The all-in-one computer monitor contains internal components and does not require a separate housing.
Video card
This card is a unit for processing images and outputting them to a display. The video card has dedicated RAM to perform these functions. A high-end video card needs to handle compelling visual features such as computer graphics engineers.
Furthermore, there are usually integration graphics instead of a graphics card. This happens when a traditional system borrows RAM for graphics processing.
Similarly, the integration graphics usually connect to the CPU, especially on laptops.
These graphics are good enough for regular calculations and cheaper than dedicated cards, but they are not ideal for intensive editing or high-end games.
Keyboard and Mouse
The keyboard happens to be one of the most common ways to communicate with the computer. There are many types of keyboards, but most of them are very similar and can perform the same basic tasks.
Besides, the mouse is also another essential tool for communicating with the computer. Usually called a pointing device, you can point objects to the screen, click and move them.
There are two main types of mice, namely optical mice, and mechanical mice. An optical mouse uses electronic eyes to detect movement and is easy to clean. Mechanical mice use rolling balls to detect movement and require regular cleaning to operate normally.
Component makers
Similarly, many computer component makers include Hewlett-Packard, Acer, Apple, Dell, IBM, Lenovo, Toshiba, and NEC.
Conclusion
Finally, a computer is a complex machine that has been assembled to perform using the above primary components and many more.
