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.

other peripheral devices.

4. I/O System - is the communication or signals between an information

processing system (computer) and the outside world (people or another information processing system) via serial ports or parallel ports.

5. BUS/Expansion Slot - are PCI slots that allow you to add other functions in the computer like modem, Ethernet card, sound card, and other add-in

cards.

6. CMOS Storage Chip - allows you to modify the date, time and sets the loading procedure when the computer starts. CMOS Setup allows you to

express bus, Ethernet, Memory bus, and Front-side bus (FSB).

9. Southbridge Interface - handles all the inputs and outputs to the many devices

connected to the computer. It coordinates the flow of data between the CPU and peripherals

and holds the PC express, PCI, USB, SATA, BIOS, and I/O devices like keyboard, mouse,

USB, audio, video, etc.

10. IDE Disk Drive Connection - IDE or ATA is used to connect hard disk drives, CD-ROM

drives, and similar peripherals

wires creates a point-to-point connection

between devices.

12. Memory Slots - allow computer

memory (RAM) chip/stick to be inserted into

the computer. Examples: DDR1, DDR2, DDR3, and DRAM

15

13. Video Card Slots - used to connect preferred video card that shows the output display of the computer to the monitor.

14. Power Connectors and Cables

Power Connectors are attached to the power supply to give power the motherboard and the other components.

Wires and Cables - to carry data or information to various parts of the

computer system.

15. Back Panel Connectors - are plugs and

ports used to connect to the external elements and are located at the back of the

computer case. These are connectors for external components like keyboard, mouse,

monitor, speakers, printer, scanner, etc.

16. Front Panel Connectors - are used to

connect to the external elements and are

located in front of the computer case such as power and reset buttons, audio

connectors (earphone and microphone), USB connectors, and optical drive.
