What is the purpose of the ALU?
Where all calculations and decisions are made.
2 of 31
CMOS battery:
Provides limited power to the low-level systems in the motherboard whilst the computer is turned off.
3 of 31
Processor socket & chipset:
The place where the processor orginally is placed. E.g. a CPU.
4 of 31
Slots:
Used for attaching storage or memory.
5 of 31
Connectors:
Allows devices to be connected such as expansion cards
6 of 31
Heat Sink
Takes away heat from inside the PC
7 of 31
Ports:
This component allows external devices to be connected. Such as headphones, or controllers.
8 of 31
Overclocking
This is a method used by a computer to make the pc run at a faster rate and be ran at higher specs.
9 of 31
Water cooling:
Water cooling is used when the PC gets too hot so it takes water to a high-speed fan and cools down the most priority parts of a PC to make sure it can run without blowing it up.

What are Registers
Small area of storage that is used for fast access used by the CPU
12 of 31
What are Cache
A cache helps speed up the process by storing frequently used instructions and data
13 of 31
What is Random Access Memory (RAM)
RAM holds all other data and instructions
that the computer may need to open and run applications or programmes
14 of 31
what is Read Only Memory (ROM)
Contains permanent instructions to make sure the computer is in correct form and that there are no faults with the hardware of the PC
15 of 31
What are Flash drives?
ADV/DIS
Technology that relates to how much memory can be accessed
Saves the data.
Data can be transferred to other devices.
Risk of losing the Flash drive.
16 of 31
What are Solid State drives?
ADV/DIS
Integrated circuit that uses flash memory to access memory which is faster and more reliable rather than most storage devices
Uses less power.
Last longer.
More expensive than an HDD.
17 of 31
What are Magnetic drives?
ADV/DIS
Commonly used storage device that is used in traditional hard drives.
Cheaper than solid state alternatives
Access rates are slower.
Damaged easily
18 of 31
What are Cloud Storages?
ADV/DIS
Storage type that can store data.
Secure.
Your files only.
Pay for expertise
19 of 31
Internal storage
ADV/DIS
Devices that are built in and fixed into the computer.
allows the data and applications to be loaded very rapidly into memory, ready for use.
Not expandable.
20 of 31
What are removal storage.
ADV/DIS
A storage type that you can remove from the computer itself.
Easy to use
Less storage capacity
21 of 31
portable storage
ADV/DIS
A storage types that is used for transferring data.
Less work
Easy access
You could lose it.
They are fragile.
22 of 31
Small computer system interface (SCSI)
An external storage device that was used in computers due to the insignificant amounts of data. It uses a parallel connection method that would send out 8 bits (of a byte) at the same time
23 of 31
Serial advanced technology attachment (SATA)
A device reliable for data transfer.
storage is slower and less reliable.
Much larger storage capacity.
power and data are separate.
very cheap
24 of 31
Serial Attached storage
A storage type that provides both power and data. 128 types being supported in one go so it is widely used in data centres. Cheaper than SAS. Larger storage capacity.
25 of 31
universal Serial Bus
Used to connect stand alone devices. E.g. keyboard printer or may be smartphone
26 of 31
Fire Wire
similar to USB used for high speed data transfer where large amounts of data is moving between devices that are not connected to an network.
27 of 31
Serial Advanced Technology Attachment (eSATA)
Allows for compact devices to be connected/ linked to a computer.
28 of 31
Network (RJ45)
Connects computers to Modems, routers or LAN's. E.g. A hybrid network hub that can be used in a home network.
29 of 31
Fibre channels
Devices used to transfer data using fibre connectivity methods/ cabling.
