From HTTP to SEO: What Do Computer Abbreviations Mean?

From HTTP to SEO: What Do Computer Abbreviations Mean?

With our lives becoming more and more dependent on technology, it's common to see abbreviations related to computers every day. You may already know that PC is short for "Personal Computer," but what about the many other abbreviations we see regularly? 

Use this article as a quick reference to help you understand what many of the most common tech terms mean. The next time you read them online or hear about them in a store, you'll be prepared!

Computer abbreviation meanings

CPU

The Central Processing Unit, or CPU, inside of a computer

An essential part of any electronic device is its CPU, which stands for "Central Processing Unit." CPUs make calculations and allow other features to run, or operate. They are often called the "brains" of a computer.

It's important to keep your computer cool so that the CPU does not overheat and damage your data.

OS

OS is short for "Operating System." An operating system allows a computer's hardware (chips, circuits, etc.) to communicate with its software. 

When you download apps and other programs, they must be compatible, or able to be used, with your device's OS.

I just downloaded my laptop's newest OS this morning.

RAM and ROM

If you are shopping for a new computer, you should pay attention to these two abbreviations.

Unlike the others on this list, these are actually pronounced like regular words instead of saying each letter individually. However, please note that "ram" also has another meaning that is not related to computers or technology.

RAM stands for "Random Access Memory," and it stores data used by documents, videos and websites. A large amount of RAM will allow your device to do many or heavy tasks without slowing down.

After I upgraded my computer's RAM, the programs that used to run slowly became super fast!

(By the way, Random Access Memories is the name of the very popular 2013 album by the French funk and electronic duo Daft Punk!)

Next, we have ROM, which is short for "Read-Only Memory." Unlike RAM, ROM cannot be changed; instead, it contains the basic instructions that electronic devices need to operate.

The software update cannot be installed on ROM since it is read-only memory and can't be changed.

HTML

A computer screen displaying HTML code, one common computer abbreviation

This stands for "Hypertext Markup Language." This is the language used to build the webpages we browse every day. 

If you click here, you can see the HTML used to create our homepage.

HTTP

Have you ever noticed the "http" at the beginning of the web addresses in your browser's search bar? It is short for "Hypertext Transfer Protocol." If you see an "s" at the end, it stands for "Secure."

Make sure the web address begins with "https" if you are sending sensitive information online.

ISP

ISP stands for "Internet Service Provider." These are companies that sell access to the internet. Depending on where you live, internet service may be sold together with phone service or other digital products.

This ISP has a bad reputation for charging customers extra fees.

SEO

This term has become very important for businesses in nearly every industry. It stands for "Search Engine Optimization."

When you "optimize" something, you make it as good or effective as possible. For companies and individuals who want to promote themselves, good SEO can make it easier for people to find them online.

We're hiring an expert to help improve our company's SEO. Right now, we appear on the fifth page of Google search results!

SIM card

Many people are familiar with SIM cards, but have you ever wondered what those letters stand for? It's "Subscriber Identifier Module." Mystery solved! 

SIM cards are small chips inside phones and tablets that allow them to be identified on a cellular network. They connect your device to your unique account or phone number.

Like RAM and ROM, "SIM" is pronounced as a word.

There is a SIM card rental service in the airport so you can use your phone while overseas.

VR and AR

You may know that VR stands for "Virtual Reality," which is an environment created in a computer that appears to be real.

You need to wear these VR goggles to play this video game.

AR, on the other hand, stands for "Augmented Reality."

"Augmenting" something is enhancing it or making it better in some way. Instead of creating a new world, like in VR, AR adds something to our real world. 

The mobile game Pokémon GO is a famous example of AR technology, but there are others as well.

IP

IP is short for "Internet Protocol," which is the set of rules that controls how data moves across the internet.

Even if you aren't in the tech industry, you may still hear about IP addresses, which are numbers that identify devices connected to the internet, such as phones, computers and even household appliances! 

Every device online has its own unique IP address.

VPN

A VPN is a "Virtual Private Network." VPNs hide your device's true IP address so your internet service provider thinks your computer is located in a different place than it actually is. They can also encrypt your data, which makes it more difficult to read and understand by anyone other than the sender or recipient.

One popular use for VPNs is "tricking" streaming services into giving access to films and television shows from other parts of the world that normally are not available.

I used a VPN to stream a foreign movie last night. Unfortunately, it didn't have subtitles, so I couldn't understand it!

Wrap-up

Even though we see many of these abbreviations every day, most people do not stop to think about what they mean. But now you know! Additionally, learning the individual words will help you recognize them when you see them separately from these abbreviations.
