Howdy Geeks, The most important part of being a Geek is Knowledge and Understanding of each of the major components that make up a computer is always a good step in learning more about computers instead of browsing Facebook, watching porn, or even good movies, seriously i don’t care.

Note: This post is just for the NooBs to learn more about computers, many of you know this by birth, LOL, so for advance users please skip to the other posts.

Here are some of the basic terms, that you should know in order to use and understand the basics of networking and computer concepts.

Important Computer Terms you should know


Here are some of the terms listed below, let’s take a look upon them.

Transistors: The computer contains millions of transistors, which are used to create machine language using logic gates that turn on and off the circuits.

Machine language: All computers and electronic devices communicate in binary, which is a series of 0’s and 1’s or Off and On electrical signals. Take for example a charm bracelet with only black and white beads – any combination of those beads would represent a distinct and unique binary number. Memorizing and understanding the pattern of a black and white beaded bracelet is pretty easy but understanding and memorizing the pattern of a beaded dress is definitely harder. Something that would help understand bigger and more complicated bead patterns can be compared to a high-level programming language. All software written on your computer is created in a high-level programming language that humans can understand. When complete, the program is compiled into the machine language that computers understand.

ASCII codes: Each binary 0 or 1 is considered a bit and each number, letter, or other character is made up of eight bits (one byte). A common method for storing and editing text is done with ASCII codes, which is one byte of binary. For example, the lowercase letter “a” has a ASCII code decimal value of 97, which is 01100001 in binary.

Motherboard: The Motherboard is the largest circuit board in the computer that holds and connects everything together. Without the motherboard, components like your processor and memory could not communicate with each other.

Computer memory: Not to be confused with disk storage, the computer memory (RAM) is volatile memory and is used to store currently running applications. When the computer is turned off, all data in the memory is lost.

Computer disk storage: A non-volatile type of memory, disk storage like a hard drive is what stores your information even when the computer is turned off. All of your personal files, documents, songs, photos, etc. are stored in disk some form of disk storage.

ROM: Another type of memory, read-only memory (ROM) is a memory chip that has data which can only be read. Most computers today have a programmable read-only memory (PROM), which is still read-only, but can be re-programmed if needed through a firmware update.

Memory capacity: All memory and storage has a total capacity that is written using abbreviations such as KB, MB, GB, and TB. See the full overview of all computer capacities for a complete understanding of all values.

Processor: The Central Processing Unit (CPU) is the component responsible for processing all instructions from software and hardware.

Software and Hardware: Software is instructions and code installed into the computer, like the Internet browser you’re using to view this page. Hardware is a physical device you can touch, like the monitor you’re using to display this page. See the differences between computer hardware and software for more information.

Input/Output: A computer works with a human by inputting data using an input device such as a keyboard, having the processor process that data, and then displaying the output on an output device such as a monitor. The printer is also another output device and is what allows you to get a hard copy of documents and pictures stored on the computer.

Expansion cards: An expansion card is a card that can be added to the computer to give it additional capabilities. A video card, modem, network card, and sound card are all examples of expansion cards. However, many computers may also have on-board devices, such as a sound card and network card that are built onto the motherboard. For a laptop computer, additional cards are added into the PC Card slot.

Programming: All software running on the computer has been created using a programming language by a computer programmer.

Operating system: Every computer must have an operating system for software to communicate with the hardware. For example, most IBM compatible computers run the Microsoft Windows operating system and have the option to run alternative operating systems, such as a Linux variant. Apple computers only run MacOS.

Network: Computers communicate with other computers over a network using a network interface card (NIC). There are two primary types of networks: a local area network (LAN) and a wide area network (WAN). The Internet is also considered a network, which uses the TCP/IP protocol.

I am the founder and editor of Tech2Hack. With a huge interest in Hacking, Programming, Customization, Web development, and more I love to share what I've learned from my experiences.


  1. It’s been a while considering that I have actually found a worth
    checking out

    blog, bulk of the blogs nowadays publish nonsense articles

    simply to make their site upgraded however the reality –
    it’s all gibberish and copied material from another person. I’m a geek and techie by

    nature and currently searching for people that I can share my

    knowledge and ideas on this particular field.
    I hope we can share our thoughts

    and understandings some time as I do really enjoy this
    topic that’s

    why I constantly search for relevant blog writers

    where I can express my self how grateful we are because of the
    high-tech and innovative

    devices, and devices we can have nowadays.

  2. Nice website yoou got there mate, I actually appreciate your time and effort updating your website with greaat deawls of useful and fresh content.

    share it to my friends.

  6. Thankkk youuuuu!
    I Stumbled across one of your other articles, led me to your website. Ive been reading your stuff non stop since! Im pretty illiterate with tech, but extremely interested/amazed with all it can do! Your the first person I’ve found that really breaks things down where a simpleton like me actually understands. You’re awesome, thank you.
