Information Technology (IT)
What is IT?
The motherboard is what holds many of a computer parts such as the GPU, RAM, CPU, heat sync...etc and is what links your parts so they can be used together.
RAM (random accessing memory) is what your computer takes from the hard drive so you have faster access to applications.
The CPU (central processing unit) is sort of like the brain which directs all the parts to do tasks. (but the CPU never does anything of those tasks)
A GPU ( graphics processing unit) like another brain with its own RAM which basically displays all your movies,games..etc. The GPU also helps reduce strain on your CPU as it can be used to display things instead of the CPU.
It is what cools and lowers the temperature of single parts of the computer like the CPU or it creates air flow inside them. You need them (or other cooling items) in your computer because many parts like the CPU or GPU may overheat causing damage onto the motherboard or maybe to the whole computer.
It basically cools a CPU or GPU by scattering the heat into the surrounding area. This will lower the temperature of the hardware so that means the hardware won't overheat and that you can overclock it
The hard drive is where the software is stored on to. This is also where all of the data is put onto.
It is what powers the internal computer by putting out low voltage DC power
It is attached onto the motherboard and without it the motherboard wouldn't run as it needs electricity for it to run.
The Basics of Computers
- Operating System
Hardware is the physical parts of a computer that you can touch and hold while the operating system is what controls the hardware and enables you to tell what the computer to do. Applications are what allows for specialized tasks to be done on a computer such as typing a document or playing a game.
Another upgrade that should be made is the OS (operating system) as this increases your security and also patches problems in the previous OS. Doing this comes with many risks such as compatibility issues so you must check that your computer can handle the upgrade. After this upgrade external upgrades might be needed as you might want different ports or maybe more of them. Know that upgrading is made only to fix problems!
In wireless networks there are 2 "modes" which are ad hoc and infrastructure mode.
Ad hoc is basically is peer to peer mode where you can directly share printers or files with other ones. This is manly used for small and temporary networks.
Infrastructure mode is for large and non temporary networks and use one or more WAP (wireless application protocol ) which allows you to use the internet, telephone...etc.
There are 2 types of computers in a network which is servers and clients. Servers basically share things like files, folders and even printers while clients pretty much accesses those shared things. One thing great about networks are that a PC can be both server, client or even both!
