Memory module

A memory module stores temporary data that your computer needs to perform tasks. Any file or application loads in the memory modules

before you can open or use them. Memory modules are categorized based on their capacity (in GB) and speed (in MHz). Faster and

higher amount of memory generally provides better performance. Common memory‑module types are:

• Dual In-line Memory Module (DIMM)—Used in desktop computers.

• Small Outline Dual In-line Memory Module (SODIMM)—Smaller in size than DIMMs. Generally used in laptop computers.

However SODIMM may also be used in some compact desktops and all-in-one computers.

System board

A system board forms the central part of computers. All other devices connect to the system board to be able to interact with each other.

The system board holds various controllers and connectors that help in exchange of data among various components of the computer. A

system board may also have integrated graphics, sound, and network capabilities. Some important components of a system board are:

• Processor socket

• Memory-module connectors

• Expansion‑card slots

• CMOS to store the BIOS

Chipset

The chipset controls the components on the system board and enables communication between various components. Generally, the

chipset is part of the system board. However, with some new generation processors, the chipset may be integrated in the processor.

Processor

Processors receive data and instructions from applications and process the data as requested by the software. Processors are designed

specifically for desktops, laptops, mobile devices, and so on. Generally, the processor designed for one type of device cannot be used on

another type of device. Processors designed for laptops and mobile devices consume less power compared to the processors designed for

desktops or servers.
