Computer Hardware Repair

Hardware in computing refers to the physical components that make up a computer and allow it to function. While software, or the instructions that your computer runs, is easy to change with updates and application downloads, making upgrades or changes to the hardware requires physically altering your computer, usually by means of getting inside it and switching out components for better versions. Computers are still largely designed using the Von Neumann architecture, which describes the use of a central processing unit interacting with a memory unit, to facilitate the processing of data from input sources like external mass storage to output devices like the screen.

Computers usually consist of some relatively similar componentry across designs, although several of the components which traditionally were modular in early computer designs have been absorbed into an integrated central motherboard. These components include the CPU, memory unit (RAM), data storage drive (HDD/SDD), graphics card, sound card, network card, and cooling unit, along with peripherals like the keyboard, speakers, mouse, and screen. Other devices may also work in tandem with the computer, and are also considered hardware, such as a printer, scanner, game controller, or webcam.
