In this blog post I will cover the various parts you need to build your own computer.
You will need a computer case. Computer cases come in four sizes the largest to smallest ATX Full Tower, ATX Mid-Tower, Micro ATX Tower, and Mini-ITX Tower. The sizes vary due to motherboard size and how they will operate depending on personal preferenece. If your are say a gamer, I would go with the ATX Full Tower and ATX Mid-Tower because gaming computers have a tendency to use larger graphic cards to ensure proper perfomance.
You will need a motherboard, this is the base where all the hardware is connected to and run on. These include the graphic cards, the sound cards, the ram, and the CPU. The motherboard when fully operational it will run a basic program called bios it shows up before any operating system is installed (like windows, linux, or mac) or hitting the delete key before startup. It allows the user to manually change the performance of a computer. This allows overclocking, a term used when outperforming a computers limitation, though it can be risky. Like the case sizes above motherboards are labled the same to corispound with cases sizes.
CPUs or central prossesing unit, is the computers heart that allows information to load faster. There are two brands intel and amd. Intel has reliable perfomance though it’s more expensive while amd is less on high perfomance it makes up for cost. There are different CPU speeds to lessen load times for an office computer you just need to be around 2.0 GHz, but a gaming computer you may want something above 3.4 GHz. The CPU physically contains copper 240 pins on it botton and goes into the motherboard (depending on cpu brand) slot that has a lever which allows the pins to stay in place. Always have a heatsink (fan or water cooled) to be placed on top the cpu because they produced alot of heat which can damage them if there is nothing to asorbed the heat.
video cards(a.k.a Graphic cards), this part allow the computer show images, play videos, and games. A basic video card is just the size of a credit card they fit inside a PCI slot on the motherboard, as for the more heavy duty cards for gaming require a 16 pin pci slots being as big as a desktop keyboard and have fans attached on them. There are two main brand names AMD and Nivida.
Ram or random acess memory, these memory sticks usually come in sets of 2 or 4. The purpose of ram is to allow a number programs to run all at once and prevent computer crashes . For video games this is nessary because even if you have the most powerful graphics card on earth you still need enough ram for computer stablity to prevent laging and at worst game freezies. The maximum amount of ram you can have is about 32 Gigs but I would just stick with 8 Gigs
HDD or Hard Drive Disk, This looks like a small steel case, it allow the computer to save information such as programs, documents, video’s, and photos. You attach this peice to motherboard using a sata cable. The largest HDD can store around 3 Terobytes of data. Right now though a new type of drive which allows a faster rate of data transfer is becoming popular called a SSD or Solid State Drive, it’s the size of a deck of cards
A disk drive which allow the user to insert disk into there computer to mainly update software drivers, videos, and games.
Lastly the OS or Operating System is the key feature you will need to have a proper computer working. There are three types Windows, Linux and Mac. Windows are the best choice if you want user freindly with customazion. Linux if you want the cheapest possible operating system. Mac if you want absolute user freindly experince though it lacks certain customization
Thats what you need in general for a computer
