30 Most Useful Computer Terms You Should Memorize
One of the biggest challenges when it comes to computer knowledge is knowing the proper terminology. Computer terms are used to describe parts and other elements within the computing world. Even if you know how to operate a computer, you may not be aware of the various terms used.
The following is a list of most useful computer terms that you should learn if you want to expand your knowledge about computers:
1. IP Address
IP address is a numerical label assigned to a device connected to the Internet. It is used to identify the device and route data packets to it. An IP address is usually assigned by a network administrator, but can also be manually entered into your computer or smartphone for convenience.
IP addresses are usually written as four numbers separated by dots e.g., 123 . 456 . 789.
The physical components of a computer, such as its processor, RAM and hard drive.
A collection of code (programs) that provides specific functions to the hardware on your computer.
BIOS stands for Basic Input/Output System. The BIOS is responsible for booting your computer, detecting and configuring hardware, and managing system resources such as RAM, hard drive space, and processor speed.
5. Operating System
The software that controls how other software runs on your computer or device. Examples include Windows, Mac OS Android and iOS.
6. CD/DVD drive
A device that reads and burns CDs or DVDs and sometimes-other types of discs.
7. CPU (Central Processing Unit)
This is the main component of a computer. It’s the part of the computer that helps it run programs, store information and do calculations. Most computers have two or more CPUs.
Random Access Memory stores data temporarily until it needs to be accessed by a program or operating system. The size of RAM determines how much information can be stored in your computer at one time and how fast it can access that data.
Hard Disk Drive is a storage device used by computers as an alternative to RAM when storing large amounts of data. A hard drive contains spinning discs with magnetic surfaces that keep them from wearing out quickly over time like other storage devices such as flash disks.
10. Command prompt
A type of window used by programmers to issue commands to their computers, such as formatting a hard drive or starting an application program such as Word.
11. Desktop wallpaper
A background image that appears on your desktop screen when you start up Windows or other operating systems.
Cache is a temporary storage area for frequently used data. By storing often accessed data in cache, the computer can access it much faster than accessing the same data from disk.
Cache is stored in memory and can be accessed by both software and hardware components of your system. The cache is usually located between processor cores (CPUs) so that each core has direct access to one or more caches.
13. Virtual memory
Virtual memory is a computer’s ability to use hard disk space to temporarily store data and programs. Virtual memory allows the computer to run faster by keeping frequently used data and programs in the fastest part of the computer, which is called RAM (Random Access Memory).
A browser is a software that allows you to access information on the World Wide Web. There are many different types of web browsers, including Microsoft Edge, Mozilla Firefox and Google Chrome. Other common browsers include Opera and Vivaldi.
15. Browser window
The part of your browser where you are typing in text or clicking on links.
HTTP is a request and response protocol used for transferring web pages. It is a client/server model, meaning that one computer makes the requests while another computer responds to them.
A Uniform Resource Locator (URL) is a string of characters that defines the address of a website or web page. You can use URLs to find and access websites, files on the internet and documents on the internet.
HTML stands for Hyper Text Markup Language. It is the basic building block of a web page and is the main language used to create web pages.
A virtual private network (VPN) is a private network that uses a public network to connect remote sites or users. A VPN allows users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
VPNs are useful for securely exchanging sensitive information, such as financial data, medical records and other personal information.
A bug is a problem with a program that causes it to behave in an unintended or unanticipated manner. Bugs can be caused by programmer errors or by misunderstandings about the requirements of a program.
A byte is a unit of digital information that consists of 8 bits. Byte is the base unit of computer storage and can be used to represent any amount of data, including numbers and text. A byte has a value ranging between 00000000 through 11111111, but it’s usually represented in hexadecimal format (base 16).
An algorithm is a set of rules and steps to solve a problem. An algorithm can be used to solve problems in mathematics, computer science, engineering and economics. Algorithms are used in many fields including computer science, mathematics, engineering, economics and biology.
An algorithm is an effective, efficient and accurate method of solving a problem; the best solution found by applying one or more algorithms
OpenGL is a cross-language 3D graphics API. It was developed by the Khronos Group, an industry consortium that includes companies such as AMD, ARM Holdings and Google. OpenGL supports many different platforms including desktop computers, mobile devices and game consoles.
SQL stands for Structured Query Language, and it’s a database language that allows you to query and manipulate data in a database. SQL is an ANSI standard, which means it has been around for more than 20 years.
The first thing to know about SQL is that it’s declarative: It doesn’t tell you what operations should be performed on your data; instead, it tells you how those operations should be performed. This makes the language easier to learn because there are fewer details about how things work behind the scenes.
25. Binary code
Binary code is a computer language. It is also called machine language and is the basis for all modern computer languages. To understand binary code, think about how you read words on paper or listen to someone speak: you use letters and syllables (words) to create meaning from the sounds they make.
In much the same way, binary digits represent information in computers; they are 0s and 1s that tell computer machines what to do.
A screenshot is a picture of your computer’s display taken in real-time, while a print screen only captures what is visible on your monitor at that moment in time. The most common use of this command is to capture images from web pages so you can share them with friends or coworkers over email or social media sites like Facebook or Twitter.
27. Cloud Storage
Cloud storage is a way to store files, data and other information on remote servers that can be accessed from any Internet-connected device. Cloud storage can also be useful if you need access to large amounts of data but do not have an unlimited amount of disk space on your computer system or mobile device.
28. Software as a service (SaaS)
Cloud computing is a form of IT outsourcing in which software applications and services are delivered as a service over an internet connection instead of being installed locally on each user’s computer or device.
SaaS has become the most common way for businesses to implement new software since it’s easy, flexible and cost-effective at providing timely access to the latest technology without having to develop everything from scratch yourself.
29. User experience (UX) and user interface (UI)
User interface refers to the screens, pages and visual elements of a website or software application. UX involves the way users interact with a website or app, and how it makes them feel.
30. Keyboard shortcut
Keyboard shortcuts are a nifty way of saving time and making your work more efficient. These are sequences of keystrokes that can be used to do things like copy and paste text or move the cursor around a document, as well as insert special characters. You can even use shortcuts to open a new tab in your browser or save an image you are working on before you exit it.
