Printers, Scanners & Photocopies – These are normally combined within the same machine if it’s multi-functional.

When building a pc, one needs to consider what they are going to use the PC for. For a college student, some uses of a desktop pc could consist of gaming, video editing, and running software. All three of these rely on each part of the computer to perform the task. One component used heavily in all three of the tasks is the CPU (Central Processing Unit). The CPU is a piece of computer hardware that

RAM: RAM stands for Random Access Memory. It is a bit like a person's short-term memory. RAM is volatile so data only exists only when the computer is turned on, and is used by the operating system and other applications.

RAM (Random Accesses Memory): RAM is used by CPU when a computer is running to store the information that it needs to be used very quickly but it does not store any information permanently.

Scanners: They are used to convert a document or image into an electronic file that can be used and stored on a computer, Sometime scanners are part of a printer but usually scanners that are the most efficient are small scanners that can be attached to a computer through an USB cable they can scan single sided or double sided documents very fast. They can scan in colour or in black and white. Scanners are essential when a company needs to keep hard copy of their files in law firm in a medical environment or in an accountancy department.

What do CPU’s do? The CPU is the Central Processing Unit; its aim is to be there the act as the brain of the computer. Other common name for the CPU is the processor. It is in control of the power the computer is receiving and using and the calculations that enable to the computer to be used. CPUs come in differing form factors and each has a particular way in which it will fit on to the motherboard. The most common manufactures of this part that people will know are Intel and AMD. The CPU is in charge of allowing programmes to be used. The CPU sorts the commands of a program into an order which enables it to be used.

Irregular Access memory is inside the PC which store the information and work with capacity memory to make lessen less and influence space for essential things to like record and documents in light of the fact that for individual protection.

Mouse is an input and pointing device that allows the user to control the graphical user interface. Keyboard is an input device that allows the user to input data and give commands to the operating system by typing. Commonly, a keyboard contains all the alphabetical letters, numbers from 1 to 9 and punctuation

CPU : This is the central processing unit, better known as the processor. This is the heart of the PC where calculations are madeRAM: RAM stands for random access memory. This part in the PC grabs the file from the hard drive and stores on its non permanent memory so that you can have multiple windows open such as word and be able to access this data faster. The more RAM the faster and more apps you can open and the bigger the files the ram can hold. However, if you are using word and your pc crashes and you haven’t saved the file to the hard drive. The work that you have done will be lost due to that RAM does not hold on to files. GPU(Graphics card): The graphics

The CPU is housed in the motherboard is considered the heart of the computer, it controls everything. CPU stands for central processing unit; it is one of the main components of a computer. The CPU or more commonly known as the processor is electronic circuitry which follows the instructions of the hardware and software on the computer, it effectively is a very efficient calculator carrying out arithmetic, logical, control and input/output operations.

Motherboard is one of the most important parts of a computer system. It is used to hold together vital components of computer, for example: CPU, memory and connectors for input and output devices.

Scanners to scan documents digitally, which once scanned can be stored in a computer, emailed or printed;

A computer is an electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. Hardware is the physical equipment of a computer system, including the central processing unit (CPU), data-storage devices, terminals, printer, etc. Software is a program or set of instructions or rules that control the operation of a computer.

ii). Printer : Printer is a device that prints text or picture on a paper and in many cases on transparencies and other media. There are many different types of printers.

Monitor – Visually Displaying the image on Screen, they come in a very of different sizes and resolutions. The monitor is an output device where is receives information from the computer to display the image on the screen in the form of pixels. This data usually comes from the Graphics Card or the integrated graphics within the processor outputted by the motherboard. This connects to the computer either via HMDI, VGA, DVI or Thunderbolt.
