Processor
A processor is known as the “brain” of the computer system, it is a chip placed on the motherboard which controls everything. The processor contains electric circuits collectively which processes the operation in the program by performing them, into movements of data inside the memory. The processor is mostly referred to as a CPU, the central processing unit has three operations. Fetch is the first operation which finds some information and data from the memory and places it in its own temporary memory, the second one is to decode. Now the CPU will decode the information which means to make sense of the data and information it had gained and the third is to execute this is where the information or data processing takes place. Processors are made by a wide range of companies (Intel is perhaps the most common) and have a performance that’s measured in ‘gigahertz’ (GHz). This means ‘cycles per second’ and 1GHz = 1 billion cycles, the more GHz a processor has, the faster it is.

Motherboard
One the most important component in a computer, the motherboard is a board containing an electric current that houses many of the essential parts of a computer. The motherboard distributes the power to all of the other computer hardware components, all connections between the PC and any device which is attached to the PC such as the mouse would have to go through the motherboard. The motherboard is only a thin plate at the bottom of the computer casing made from fiberglass and copper which holds the CPU, connectors, memory and expansion cards. Due the motherboard being an important component, it connects directly and indirectly to every single part of the computer. In easier terms the motherboard could be described as a green block when playing with Lego, as when you’re trying to create something using Lego and the green block is the base of the construction, just like a motherboard how all of the components are placed on top of the motherboard to form the computer.

BIOS
BIOS stands for basic input/output system, the BIOS is located on the ROM chip that would come with the computer. The BIOS is the component that starts up the PC when it is turned on, it could also be seen to be an important diagnosis tool as it is able to check the hardware arrangement against the data arrangement and can check the network security so that’s information can only be modified with permission. The BIOS can also handle the input and output of the computer, from attached devices such as the mouse, keyboard and printer. When you are starting up your PC the BIOS will check all your programs to see if they are operational and in place and then it’ll load your operating system into your RAM from your hard disk.

Fan and Heat Sink
The modern fans inside a computer would pull out the heat from the computer, however previously the fan would bring in cold air. The fan would help by cooling down the chips such as 3D video card as that would create a lot of heat, and therefore it could affect other chips around it and the computer may get overheated and turn off. The fans role to avoid this would to be suck out the hot air to prevent it from overheating. The heat skin is a square shape attached to the processor, it has a large surface area so therefore the heat transfer would be increased and it takes the heat from the processor and it would not overheat. The fan and heat sink are both placed on top of the motherboard.

Specialized Cards
Specialized cards such as network and graphics card are used to increase the performance of the computer. Most motherboards would come with integrated graphics which is where the card is stored on the motherboard. A specialized graphics card can increase the performance of the computer in terms of giving a higher resolution and better quality, people may add a better specialized graphics card if they like to watch movies to experience high definition. A network card connects the computer to the computer network, some networks cards have an antenna for them to be able to connect to the network. A sound card is an internal computer accessory card which helps the input and output of sound from the computer through the control of a program.

Ports
The function of a port is a connection point for a internet or external device, for example an external device would be a mouse it is connected into the port for it to be able to used within the computer, or an example of an internal port would be hardware as it would have a port to be connected into for it to be connected to the computer. Ports have a number of different designs and different functions: Serial ports which are mostly used for connecting a mouse or keyboard. Parallel ports are mostly used for printers. Small computer system interface (SCSI) ports can connect up to seven devices. Universal serial bus (USB) ports can be used to connect many devices such as keyboards, external hard drives, USB and iPhones. A motherboard provides a number of USB pin headers which allow connection to the USB ports which are at the front of the computer case.
