Computer Terms and Jargon
Is a Short form for application, which is a program for mobile devices like tablets and phones.
Any advertising software which automatically plays, displays, or downloads advertising material to a computer after the software is installed on it or while the application is being used.
Bandwidth in computer networking refers to the data speed supported by a network connection. It is most often expressed in terms of bits per second (bps) or megabits per second (Mps). The term represents the total distance between the highest and lowest signals on the communication channel (band).
A piece of software that is made available for testing, typically by a limited number of users outside the company that is developing it, before its general release.
Is short form for “weblog” an online journal or informational website displaying information in the reverse chronological order, with the latest posts appearing first.

The term Broadband is usually used to describe any high speed connection to the internet.
Is a space in your computer’s hard drive and in RAM memory where your browser saves copies of previously visited Web pages. Your browser uses the cache like a short-term memory. Instead of downloading an image from a recently viewed website, it will load the image from your cache folder, thereby making the browsing process a little quicker.
Casting/Cast vs Mirroring
Both transmits images via the internet/wifi. While the terms are used interchangeable there is a difference in how they function.
- Casting only the video or movie will appear on the screen. You can control the video on your phone, but you can also close the app and do other things without interrupting the video as long as the phone is still connected.
- Mirroring lets you mirror what’s on your phone’s screen to a bigger screen, like a smart TV. Exactly what’s showing on your device will appear on the TV, whether it’s a video, a photo, or a Settings menu. Whenever you do something on your phone (like navigating to a different app), that action will also be shown on the other screen.
Some web pages ask you to type in a string of letter and numbers or to choose images from a series of images that have a particular item in them before something can be sent or saved to their site. They are used because computers are unable to repeat them or distinguish them like humans can. This helps block automated computer process from overwhelming their website with spam. The acronym CAPTCHA actually stands for “Completely Automated Public Turing test to tell Computers and Humans Apart”
Compact Disc Read Only Memory

Internet vs World Wide Web (WWW) :
While these terms are used interchangeable they are not the same. The Internet is the wiring that allows computers to communicate while the World Wide Web is the system that operates via the wiring. So if you think of the World Wide Web as a highway, the internet would be the pavement.
Internet Protocol (IP) Address
A string of four numbers separated by periods (such as 192.168.211.100) used to represent a computer on the Internet. It is the computers digital address on the WWW.
Internet Service Provider (ISP)

RAM VS ROM VS CMOS
RAM is the abbreviation form for Random Access Memory is the short term memory or information storage in a computer basically used to store running programs and data for the programs. Usually, the contents of RAM are accessible faster than other types of information storage but are lost every time the computer is turned off.
Rom is the abbreviation form for Read Only Memory it is the long term memory or information storage of the computer. It holds all the basic instructions the computer needs to do very simple stuff, such as making the letter “X” appear on the monitor when you press the “X” key. It is not easily altered, so losing power does not affect it.
Cmos is the abbreviation form for Complementary Metal-Oxide Semiconductor. While not widely discussed it is a small onboard chip inside the computer that is powered by its own small battery so when power is disconnected it still retains the information. Since it is basically used to store information ranges from the system time and date to system hardware settings for electronic devices like computers and cameras, it is alternatively referred to as a RTC (real-time clock).
Is a device that’s software and hardware are designed to move data between computer, phones, tablets, printers etc. Routers make sure traffic goes where it needs to go. It is like police directing traffic in your neighborhood. The device can be either/or hardwired or Wifi
