Components Of Computer System
Computer System:
A computer device comprises several factors that aid in effective processing and operation. The computer includes five essential components that make data processing easy and valuable. By definition, a computer system's components make an electrical device work more swiftly and efficiently.
There are five fundamental elements, including:
- Input Unit
- Output Unit
- memory device
- Command Unit
- Arithmetic and Logic Unit
Input Unit:
- Computers are controlled via input units or devices such as keyboards, joysticks, etc., allowing users to give commands in numbers, alphabets, graphics, etc.
- Then, responses are output in a language that either humans or the machine has been programmed to understand.
- These inputs are also transformed into computer language after analysis.
- For instance, if we type text into a notepad using a keyboard, the computer will process the data and show the results on the screen.

INPUT AND OUTPUT UNIT
Output Unit:
- The monitor is among the most fundamental. Anything we write on the keyboard or click with the mouse is displayed on the monitor.
- Therefore, the output unit gives us the overgrowth when all processing is finished inside a device's medium.
- When we use an ATM, for instance, we input our information, such as our preferred language, PIN, planned withdrawal amount, etc., and the cash dispenser then disburses the money.
- The cash dispenser is an output unit in this scenario.
Memory Unit:
- The central processing unit's (CPU) memory unit instantaneously saves data entered into a computer through an input device.
- The Memory Unit conveys the data further to the other CPU factors due to the existence of some previous programming.
- Also, the computer saves the results of our instruction in its memory unit before providing the results to the user.
- Prior to being transferred to the other parts, the memory of the CPU stores the data entered via input devices.
- Much like how ready output is stored in memory before being given to the user.

Control Unit:
- The control unit gathers the information provided by the input unit, processes it, receives the results, and then displays them to the user.
- Unit on Arithmetic and Logic is the hub of all computing-related processing activities.
- Calculations, arithmetic operations, data comparison, and decision-making are all covered in this unit.
- It contains circuits for addition, subtraction, multiplication, and other counts.
- As its name implies, the CPU's Arithmetic and Logical Unit handles all arithmetic and mathematical computations.
- It can also conduct additional tasks like data comparison and decision-making.
- Decision-making and data comparison are other activities it is capable of performing.
- The ALU comprises circuits that can do addition, subtraction, multiplication, division, and other numerical operations in computations.

GPU:
- GPU is yet another essential part of the computer.
- High-end visuals, like those set up in video games, are produced with the assistance of the graphics processing unit or video card.
- People who use resource-intensive software and who must execute their work through illustrations, such as 3D modelers, can also profit from good graphics like these.
- Generally, it has direct communication with the monitor.
RAM:
- The part of a computer that gets mentioned the most is RAM.
- RAM is frequently called volatile memory since it is deleted whenever the computer restarts.
- It keeps track of information on constantly processed and accessible programs. It facilitates speedy program startup and shutdown.
- It is getting older and older because of its reduced speed.
ALU:

Storage Unit:
- A hard disc drive (HDD) and a solid-state drive (SDD) are used by computers to store all their data.
- Hard disc drives are discs that store data and allow a mechanical arm to read that data. Similar to SIM cards, cell phones are solid-state drives.
- They are quicker than hard discs and have no moving elements.
- It takes no time because no mechanical arm is required to locate the data on the drive physically.
A Video Graphics Array Port:
Smaller laptops and more current video cards might not have a VGA output port because of their compact design.nsure that the behaviour of some virtual functions remains intact.
Desktop computers and other display devices commonly have a connector called a video graphic array (VGA) port.
This feature is typically found on the side or back of a monitor or display screen and facilitates screen or visual sharing with another device.
Specialised VGA cables are required to enable this sharing. A laptop or PC may also require a VGA connector in order to connect to a projector.
The visual quality is frequently impacted by the number of connectors in the port.
