Being computer savvy is not about knowing the best graphics card or buying cheap RAM. It’s about knowing how things work on your computer. Below are some common terminologies to help you get started.
CPU stands for Central Processing Unit. It’s the hear of your computer that does all the work. Basically, your CPU runs all the functions of your computer. Everything is powered through your CPU when it processes all the information you enter, from typing to clicking. A CPU’s power is calculated in GHz (gigahertz). The higher the GHz unit, the better, because you will need more power for running the latest software.
RAM Stands for Random Access Memory. Think of your RAM as a temporary storage compartment in your computer.
When you launch multiple apps on your computer, your RAM goes into action and keeps them running in the background. So, if your computer lags while you open MS Office application along with your browser, it means you need more RAM, not a different computer.
ROM stands for Read-Only Memory. It’s the permanent storage compartment of your computer, where all your programs are stored. ROM comes in SSD (Solid State Drive) and HDD (Hard Disk Drive). The former boots your computer faster while the latter is old and takes time to load apps.
The purpose of your ROM is to store files and applications to start your desired program. Once the application is launched, your RAM takes over and keeps it running in the background.
4. Software/Operating System
Software is a computer program that makes your life easy. Moreover, it provides a convenient visual representation of your task. For instance, your browser is a software that shows different websites.
Your MS Office applications allow you to create documents. However, your operating system is the visual representation or a platform where all software programs are loaded. Apple computers run on macOS, while PC manufacturers support Microsoft Windows.
Now that you know the main parts of your computer, you can build your dream PC. If your work requires opening multiple tabs on your browser along with other software, you should buy a computer with at least 8 GB RAM. Iif you want a computer for streaming online media, trade RAM for a faster CPU.
