ASP → Active Server Page or Application Service Provider (pending on context)

  • Active Server Page => A web page with one or more embedded ASP scripts.
    • Uses *.asp or *.aspx for the extension, as opposed to *.html or *.php
    • Content is processed by the server as opposed to being processed locally by your browser
    • Mainly used for sites that are more 'dynamic' or have frequently changing information/data

BitTorrent → A form of Peer-to-Peer that utilizes shared bandwidth to cut down on the strain to the distributors system(s). Although BitTorrent was originally created for legit purposes, it's kind of been adopted by Hackers and Software Pirates to share their information/data illegally. Due to this, you will NOT find much information on Torrents, or other P2P (Peer-to-Peer) software.

Blog → Slang for "Web log", originally created as forms of online diaries but has since evolved to certain news sites, etc. due to simplicity of updating and editing.

Blu-Ray → Similar to a CD or DVD, but much higher capacity. Winner of the "HD Wars", beating the failed format of HD-DVD.

CC → Depends on context, normally references "Credit Card", but when referenced in regards to email stands for "Carbon Copy", similar to BCC but the names will be shown to all in the To: and CC: fields.

CD and CD-ROM → A CD (Compact Disc) is a 4.75 inch (12 cm.) disc that contains data, while the CD-ROM is the device used to read CD's.

CGI → (Common Gateway Interface) A standard for running external programming from a web server.

Chipset → The architecture of an integrated circuit.

Clean Room → A fully sterile room, void of dust, static, or anything else that can potentially damage electronic parts.

Clipboard → A section of RAM that temporarily holds information to be pasted or manipulated later.

Clock Speed → The clock speed is the frequency which determines how fast devices that are connected to the system bus operate. The speed is measured in millions of cycles per second (MHz or megahertz) and is generated by a quartz crystal on the motherboard which acts as a kind of metronome. Devices that are synchronized with the clock may run faster or slower but their speed is determined by multiplying or dividing a factor by the clock speed. (GHz or gigahertz, equals 1000MHz or 1024MHz pending on the source).

CMOS[2] → Complementary Metal Oxide Semiconductor → Pronounced see-moss, CMOS is a widely used type of semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. This makes them particularly attractive for use in battery-powered devices, such as portable computers. Personal computers also contain a small amount of battery-powered CMOS memory to hold the date, time, and system setup parameters.

CMYK → Stands for Cyan, Magenta, Yellow, and Black, subtractive color model used for print. Opposite of RGB (Red Green Blue)(Additive) used for computers, and web.

Codec → A technology for compressing and decompressing audio and video. If you have issues playing a music file or video it's possibly a codec issue. VLC is a multimedia player that has a high quantity of codecs built in and is recommended if you experience problems with a different player.

Command Line → (also called "CMD Line" or Command/CMD Prompt) is a DOS style interface for entering in commands.

  • In Windows XP, you can access the Command Prompt via the Start Menu ⇒ Run ⇒ Type 'cmd' and press enter. Do NOT include the ' marks.
  • In Windows Vista and Windows 7, doing the above will give you the Command Prompt without Administrative Rights, if you need those:
    • Click the Start Orb and in the Search box at the bottom type 'cmd' and wait for "Command Prompt" to be shown, right click it and click "Run as Administrator"



F - J


Favorites → See Bookmarks

FTP → File Transfer Protocol → Used for sending data to or from a server, mainly used in transmitting data to a Web Host.

FTP Client → Software that sits on your computer, used to connect to the FTP server for use in downloading/uploading information.

FTP Server → The location (normally a location on your Web Hosts servers) where you store your files and information that is displayed when a visitor views your site.


GeForce → Line of graphics cards created by nVidia.



IRC → Internet Relay Chat → Essentially what gave 'birth' to chat rooms. Still in wide use today.

Life Cycle → A length of time given by the developer of software to determine how long standard support will be given before support is dropped in light of newer versions.


Media Cards → See Card Reader for types.


nVidia → Graphics card creators responsible for the GeForce line of video cards.


P - T


P2P → Peer-to-Peer → See BitTorrent for some information. Due to the use of P2P software to promote use of software piracy, we wont give much details on the topic.



Radeon → Graphics card created by ATI (now owned by AMD).


Screen Cap (or Screen Capture) → See Screenshot

Screenshot → To take a picture of your full screen (or section) for display purposes. Works great while creating tutorials or to show error messages to technical support.


U - Z



VM → Virtual Machine → Think of a "Computer within a computer".





0 - 9


16bit → Old legacy software that ran in the same address space as the rest of the system. It was limited to the 8.3 filename structure (ex. msdos.sys) and when software crashed it normally crashed the entire computer.


32bit (x86) → Unlike their 16bit counterparts, 32bit applications run in different address spaces so that a typical program crash wouldn't always take out the entire computer. 32bit software also allows for longer file names (not restricted to the 8.3 structure). Most common software today is 32bit, but is on the move to the newer, faster, 64bit.


64bit (x64) → Newer then 32bit and allows for more simultaneous data streams for faster responsiveness. 64bit is still new enough[3] that not all software can run inside a 64bit environment.


  1. The BIOS is an advanced interface that can cause damage to your system if you are unfamiliar with it and therefore we recommend not messing with it unless you know what you’re doing.
  2. Often confused with BIOS
  3. 64bit Windows is slowly making it's way as the standard for Windows based desktops, while Linux has been utilizing 64bit for a longer period of time
Personal tools
