What is It
Components of the Computer System Case
The computer case serves mainly as a way to physically mount and contain all of the actual components inside of a computer, like a motherboard, hard
drive, optical drive, floppy disk drive, etc. They typically come bundled with a power supply.
Computer System Case is the enclosure for all the interior components of a
computer. It has ports, drives, and connection on the external part of the case to
connect other devices and peripherals. It is also called the system case or computer
Components of a System Case
1. Drive bay – is a standard-sized area for
adding hardware to a computer.
2. Power supply – is an
electronic device that supplies electric energy to
the computer.
3. Ports –refer to the
female part of the
connection that is used to connect a monitor,
webcam, speakers, or other peripherals devices.
4. Connector –is a wire that joins electrical circuits
together. It can either be a male (with pins) or female
(with holes).
10
Computer System Case (Front and Back)
The Internal System Unit
The computer is a collection of different devices connected to a central
processing unit (CPU). The system unit encloses and connect some of the hardware
components that make up the computer system.
The Two Most Important Parts of the Internal System
1. Microprocessor – is the one that
controls and processes data
information.
2. Memory Units or Random Access
Memory (RAM) – is inserted or
placed in a slot on the motherboard.
11
Inside the System Unit
The system unit in the main case of a computer. The system unit contains the CPU
or microprocessor, disk drives, memory, power supply, sound card, video card, and
cooling fan.
Parts of the Internal System Unit
12
Other Parts of the Internal System Unit
Three Kinds of Memory
1. RAM (Random Access Memory) is also called the main memory. Data and
programs are placed here while the CPU is processing them.
2. ROM (Read Only Memory) –stores important programs for example, to start
the computer. ROM information cannot be erased even when power is off.
3. CMOS – Complementary Metal-Oxide-Semiconductor) stores the date,
calendar, and current time of the computer. It powered by batteries.
Common Types of Internal Storage
1. Hard Disk Drive or HDD - is spanning data storage device used for storing
and retrieving digital information.
2. Solid State Drive - is a solid-state storage device that uses integrated circuit
assemblies as memory to store data while the computer system is off. It has
no moving (mechanical) components, unlike HDD.
Power Supply - provides power to the CPU, motherboard, hard disk, and
components inside the computer. It contains a transformer, voltage control, and a
cooling fan.
Video Card - also known as the graphic accelerator card or simply graphics card
its main function is to generate video and images to a display such as monitor.
Sound Card - is an internal computer expansion card that facilitates economical
input and output of audio signals to and from a computer under control of
computer programs.
Internal Buses - carry the data or information around different components in the
computer.
Types of buses
1. Internal Bus – is also called internal data bus, memory bus, system bus, or Front-Side-Bus (FSB). It connects all the internal components of a computer
(such as CPU and memory) to the motherboard. 2. External Bus - connects the different external devices, expansion slots, I/O
ports, and drive connection to the computer. Accelerated Graphics Port
(AGP), Universal Serial Bus (USB), and FireWire are examples of the external
busses.
Cooling System - is needed to ensure that the processor chip is cooled to a level
that it operates efficiently.
Heat sink – is a metal component attached to the CPU with fins designed to
dissipate heat and therefore cool processor.
