What are the main components of the system unit?Qquora
Updated: 21st November 2019
There are six main system unit components:
- Motherboard – a system core.
- Processor – a computer engine, its brain.
- RAM (random access memory) – primarily memory.
- Hard Drive – a system memory that storages data in a form of archives.
Furthermore, what are the system unit?
The system unit, sometimes called the chassis, is a box-like case housing the electronic components of a computer that are used to process data. System unit components include the processor, memory module, cards, ports, and connectors.
The hardware components—video card, processor, memory, motherboard and hard drive—are the same for all computer systems.
- Central Processing Unit (CPU) The CPU is the "brains" of the computer.
- Random Access Memory (RAM) RAM is variable in a computer.
- Hard Drive.
- Video Card.
A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent, and a control bus to determine its operation.
The Three Major Components of a Computer System

- Memory modules.
- Disk drive.
A closed system exchanges energy, but not matter, with its environment; like a computer or the project Biosphere 2. An isolated system exchanges neither matter nor energy with its environment. A theoretical example of such system is the Universe.
The main circuit board of a modern computer is called a motherboard. Its main function is to act as the seat for the Central Computing Unit (CPU) Random Access Memory (RAM) and ports for other peripherals such as Hard Drive (HDD), Keyboard and Mouse and Display ports for the Monitor.
The two typical components of a CPU include the following:
- The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
- The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
Inside the system unit contains the motherboard. The motherboard is the "glue" of the computer. It connects the CPU, memory, hard drive, optical drives, video card, and sound card together. The front of the motherboard are peripheral card slots.
A basic computer has at least 8 basic components which include a computer case or tower, motherboard, Central Processing Unit (CPU), Power Supply Unit (PSU), Random Access Memory (RAM), hard drive (HDD), Graphic Processing Unit (GPU) and some type of optical drive which would be your CD/DVD drive.
The major hardware components of a computer system are:
- Main memory.
- Secondary memory.
- Input devices.
- Output devices.
The base of operations for the brains of a computer is the motherboard. The computer brain is a microprocessor called the central processing unit (CPU). The CPU is a chip containing millions of tiny transistors.
Other names for the system unit include the computer chassis, cabinet, box, tower, enclosure, housing, or simply case.
- Parts of the Unit. These are some of the major components you are going to find inside your system unit.
- Hard Disk Drive.
- Power Supply Unit.
A typical desktop computer consists of a computer system unit, a keyboard, a mouse, and a monitor. The computer system unit is the enclosure for all the other main interior components of a computer. It is also called the computer case, computer chassis, or computer tower.
What Are the Four Basic Functions of a Computer? The four basic functions of a computer are input, processing, output and storage.
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions. Most computer resources are managed by the CU.
A computer is made up of the following components:
- Central Processor Unit (CPU)
- Main memory RAM -- Random Access Memory.
- disc drive.
- hard discs.
- Visual Display Unit (VDU) and.
There are basically for basic functions of computers - input, storage, processing and output. These are described below: Input: Receiving or accepting information from outside sources. The most common way of performing this function is through the information entered through the keyboard and the click of mouse.
Chips are made of silicon with embedded transistors that can be turned on or off, which is the language of 1's and 0's that computers understand.
- Central Processing Unit.
- Random Access Memory.
- Read-Only Memory.
- Secondary Storage.
Processing devices are the components responsible for the processing of information within the computer system. This includes devices such as the CPU, memory and motherboard. Storage devices are components which allow data to be stored within a computer system.

- PROCESSORS The CPU (central processing unit) is the 'brain' of the computer.
- MOTHERBOARD This is the main circuit board for the computer.
- BIOS BIOS stands for Basic Input/output System.
