Introductory Message
For the facilitator:

Welcome to the Computer Systems Servicing NCII G11 module on Parts of

the Motherboard & their Functions.
This module was collaboratively designed, developed and reviewed by
educators from Schools Division Office of Pasig City headed by its Officer-In-
Charge Schools Division Superintendent, Ma. Evalou Concepcion A. Agustin in
partnership with the Local Government of Pasig through its mayor, Honorable
Vico Sotto.
The writers utilized the standards set by the K to 12 Curriculum using the
Most Essential Learning Competencies (MELC) while overcoming their personal,
social, and economic constraints in schooling.

This learning material hopes to engage the learners into guided and
independent learning activities at their own pace and time. Further, this also
aims to help learners acquire the needed 21st century skills especially the 5 Cs
namely: Communication, Collaboration, Creativity, Critical Thinking and
Character while taking into consideration their needs and circumstances.

In addition to the material in the main text, you will also see this box in
the body of the module:

Notes to the Teacher

This contains helpful tips or strategies that
will help you in guiding the learners.

As a facilitator you are expected to orient the learners on how to use this
module. You also need to keep track of the learners' progress while allowing
them to manage their own learning. Moreover, you are expected to encourage
and assist the learners as they do the tasks included in the module.
For the learner:

 LESSON

PARTS OF MOTHERBOARD & THEIR FUNCTIONS

The motherboard is one of the components of the system unit that
performs major functions to run our computer. All the devices (input &
output) we use and other important parts of our computer are attached to
our motherboard.

In this lesson, we are going to learn the parts of the Motherboard

and the functions of every component.

1. CPU Socket
 Also known as CPU Slot or CPU Holder
 This component of the motherboard holds the CPU (Central Processing
Unit) and allows replacing of the component without soldering.
2. RAM Holder
 Also known as Memory Holder or Memory Slot
 This component is where the memory module or memory card will
be inserted.
 Some motherboard comes with two to four slots.

3. Power Supply Connector

 This part of the motherboard is where the power supply unit cable
connector can be connected
 Types of PSU Connector
1. 24 pins – main power connector that provides power to
the motherboard
2. 4 pins – provides power to the CPU
3. 8 pins – provides power for faster dedicated graphics cards
4. Northbridge Chipset

 Also known as Memory Controller Hub

 This chipset handles the data-transfer of memory, CPU, and Video
Card thus responsible for tasks that require the highest performance.

5. Southbridge Chipset
 This chipset component provides support for a wide variety of devices
with many differing bus speeds and designs.
 Control over secondary buses such as USB, IDE, PS/2, BIOs and Ethernet.
6. CMOS or BIOS Chipset
 (Complementary Metal Oxide Semi-
conductor) is also a chipset which contains
the BIOS (Basic Input Output System).

7. EIDE Slot/Port
 This part of the motherboard is where the
IDE cables are connected intended for drives
including Hard Disk Drive (HDD) and Optical
Disk Drive (ODD).

8. SATA Port/Slot
 This is used to connect SATA drives into
the motherboard including Hard Disk Drive
(HDD) and Optical Disk Drive (ODD).
 SATA (Serial ATA) has a faster transfer
rate than IDE

9. AGP (Accelerated Graphic Port)

 It was designed specifically for AGP video cards.
 It was originally designed as a successor to PCI-type connections for
video cards.
10. PCI (Peripheral Component Interconnect) Slot
 It is a built-in slot on a motherboard that allows for the attachment
of various hardware components such as network cards, modems,
sound cards, disk controllers and other peripherals.

11. PCI-EXPRESS Slot

 PCIe was designed to replace PCI, PCI-X, and AGP.
 It is the most recent and high-performance standard for expansion
cards that is generally available on modern personal computers.

11. Front Panel Pins

 These are pins in the
motherboard that will connect
the Power Button, Reset Button,
Power LED, Mini Speaker, USB
ports and other ports to the
motherboard

12. PS2 port

 It is used to connect PS2 mouse and keyboard

13. USB Port

 This part of the motherboard is used to connected USB Devices
and peripherals

14. HDMI Port

communications and isochronous real-time data transfer.
 It was developed in the late 1980s and early 1990s by Apple, which
called it FireWire, in cooperation with a number of companies, primarily
Sony and Panasonic.

19. E-SATA Port

 It is a SATA connector accessible from outside the computer, to
provide a signal (but not power) connection for external storage
devices.

20. LAN Port

 Also known as Network Port
 LAN port allows a computer to connect to a network using a
wired connection.

21. Audio Port

 An audio port is used for an audio device such as speakers, headphones or
a microphone to be connected.
