Such as the CPU & RAM, it also has other connectors for other components like SATA, M2, Fans, USB, Audio, Speaker, Wireless, VGA, DVI and more.
SSD (SOLID STATE DRIVE)
A solid-state drive is a storage device that uses integrated circuit chips to store data on flash memory.
There are several types of SSD drives which allow for different speeds, abilities, and slot types.
This type allows the drive to be more resilient to knocks and drops as well as being much faster than normal HDD drives.
SSD drives can increase speeds from 4 – 10 x or even further depending on the system.
RAM (RANDOM ACCESS MEMORY)
RAM is a long thin rectangle PCB board that holds storage chips that slot into the motherboard on your computer which help to provide a quick and temporary storage.
Random access memory is a form of computer memory that can be read or changed in any order and mostly used to store needed data and code.
Data cant be stored long term on RAM.
CPU (CENTRAL PROCESSING UNIT) - PROCESSOR

It also comes with buttons usually the left and right which allow you to open applications, move things around , etc..
They can also come with a middle scroller and side buttons.
A keyboard is a device that acts like a typewritter which is fitted with electronic switches which send the keystrokes to the computer which in turn makes it visible on the screen.
NETWORK CABLES (ETHERNET)
Network cables are used to connect one device on the network to other network devices or to connect two computers to share other devices like printers and scanners.
ETHERNET OVER POWER
Allows you to run data over electrical power on existing wiring in the property.
Saves having to lay extra cable or if you are having issues with wireless.
WIRELESS REPEATER (EXTENDER)
A Wireless repeater or otherwise know as extender is a device that hooks up to an existing router or access point and amplifies the signal as to increases the overal strength of the signal and spread it further around a location.
COMPUTER SPEED UP
When a computer is running slow the computer may need a cleanup , software troubleshooting and optimisations for it run quickly again.
