This document provides information about the key components of a motherboard, including a definition and overview of motherboards. It describes the main components of a motherboard, including the inductor, capacitor, CPU socket, northbridge, screw holes, and memory slots. For each component, it provides a definition and visual example of what that component may look like on a motherboard.

2. Componants Of Motherboard

3. • Alternatively referred to as the mb, mainboard,
mboard, mobo, mobd, backplane board, base board,
main circuit board, planar board, system board, or a
logic board on Apple computers. The motherboard is
a printed circuit board and foundation of a computer
that is the biggest board in a computer chassis. It
allocates power and allows communication to and
betweenthe CPU, RAM, and all other computer
hardware components.
Defination Of Motherboard

4. Motherboard Overview
• A motherboard provides connectivity betweenthe hardware
components of a computer, like the processor (CPU), memory (RAM),
hard drive, and video card. There are multiple types of motherboards,
designed to fit different types and sizes of computers.
• Each type of motherboard isdesignedto workwith specific types of
processorsand memory, sothey don't workwith every processorand
type of memory. However, hard drives are mostly universal and work
with the majority of motherboards, regardless of the type or brand.

5. Motherboard Components
• Inductor
• Capacitor
• CPU Socket
• Northbridge
• Screw Hole
• Memory Slot

6. Inductor
• Short for electromagnetic coil, a coil is conducting wire such as
copper shaped in a helical form around an iron core. The coil
creates an inductor or electromagnet to store magnetic energy.
Coils are often used to remove power spikes and dips from power.
The picture is an example of an inductor on a computer
motherboard.

7. Capacitor
• A capacitor is a component made of two or sets of two conductive
plates with a thin insulator between them and wrapped in a ceramic
and plastic container. When the capacitor receives a DC (direct
current), a positive charge builds up on the plate (or set of plates) while
a negative charge builds up on the other. This charge, which is
measured in microfarads on a computer capacitor, remains in the
capacitor until it is discharged. In the image, is an example of what a
capacitor may look like on a computer motherboard.

8. CPU Socket
• When referring to a processor, a CPU socket orprocessorsocket is a
connection that allows a computer processor to connect to a
motherboard. For example, the Socket 370 is an example of such a
socket. The picture shows an example of what a socket may look like
on a motherboard. Although there were computers that used the slot
processor, most computers today and in the past have used socket
processors.

9. Northbridge
• Alternatively referred to as the PAC (PCI/AGP Controller) and nb,
the Northbridge is an integrated circuit responsible for
communications between the CPU interface, AGP, and the memory.
Unlike the southbridge, the northbridge is directly connected to these
components. It acts as a "bridge" for the southbridge chip to
communicate with the CPU, RAM, and graphics controller. Today, the
northbridge is a single-chip that is north of the PCI bus, however,
early computers may have had up to three separate chips that made up
the northbridge.

10. Screw Hole
• Sometimes referred to as a standoff and spacer, standouts are small
metal orplastic screwsthat attach to a computer case and hold the
motherboard in place. The picture helps give an example of a
standout. In this picture, the left standout has a screw inserted in
the hole to help demonstrate how it works. The motherboard would
be placed between the standout and the screw.

11. Memory Slot
• A memory slot, memory socket, orRAM slot allows RAM (computer
memory) to be inserted into the computer. Most motherboards have
two to four memory slots, which determine the type of RAM used
with the computer. The most common RAM types are SDRAM and
DDR for desktop computers and SODIMM for laptop computers,
each having various types and speeds. The picture below is an
example of what memory slots may look like inside a desktop
computer. In this picture, there are three open and available slots for
three memory sticks.
