| Pixels | "Pixel" is short for "Picture Element." Small little dots are make up the images on computer displays. |
| Bits | (Binary digit) The smallest binary unit a computer can work with. (Bit combinations represent one character) |
| Nodes | Point of connection to a network |
| Bytes | A computer's memory and storage is measured in bytes. MB=million bytes, GB=billion bytes, TB=trillion bytes) |
| Motherboards | A motherboard contains the computer's circuitry and components CPU, Operating System, RAM, ROM, etc. |
| USB ports | USB standardizes the connection of computer peripherals, such as keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters to personal computers. |
| Flash drives | A USB flash drive is a commonly used external storage data storage device. It is considered an external drvice because it's plugged into the computer. Some external storage devices include: flash drives, SD card, camera cards, etc. |
| Internal storage devices | Storage devices that are totally inclosed in the computer: hard drives, CDs, DVD's Blue ray disks. |
| Blue-ray discs | Blu-ray Discs are optical, high density storage designed to hold much more and replace the DVD format. |
| Magnetic vs optical storage | Optical storage uses a laser beam to read/ an optical disk (stores a lot more and is more reliable). Magnetic storage is the hard drive and must be shielded --less reliable. |
| System software | System software is computer software designed to operate and control the computer hardware and to provide a platform for running application software. Its utility software helps analyze, configure, optimize and maintain the computer. |
| Application software | Application software is designed to help the user perform specific tasks. Examples include office suites like word processing, spreadsheets, databases; accounting software, graphics software and media players. |
| Defragmentation | The disk defragmenter is part of the operating system. It rebuilds fragmented files (regroups scattered portions of files) so they become whole again. This also helps use hard disk space more efficiently. |
| Free vs purchased software | Freeware: Totally free Shareware: Temporarily free, with request to donate money Commercial: available for purchase |
| Cookies | A small text file that contains a unique ID tag, placed on the user's computer by a website. Websites can access your cookies unless you have the option turned off. They can be useful. |
| Broadband connection | High-bandwidth Internet connections for faster downloads and uploads (Fiber optics, dsl, satellite, and cable). Dial-up service, on the other hand, is a low-bandwidth, narrow-band connection. |
| Fiber optic | A flexible, transparent fiber made of glass (silica) or plastic, slightly thicker than a human hair. Transmits over longer distances and at higher bandwidths (data rates). Not limited by distance, seldom disrupted. |
| Satellite | Satellite service mainly for people who live in remote areas where DSL and cable are not available. Does NOT rely on copper wiring and is NOT limited by distance. Uses a dish. May be interrupted by high buildings, tall tress, and mountains. |
| Cable | Uses the same technology that provices dable tv. Very popular due to its speed and widespread availability. |
| DSL | DSL signals are sent along ordinary telephone lines. |
| Wi-Fi | Wireless fidelity |
| IM | Instant Messaging: a form of communication over the Internet, that offers an instantaneous transmission of text-based messages from sender to receiver. |
| Social networking | The grouping of individuals into specific groups, using websites as social sites (like facebook or MySpace). |
| The most common means of Internet communication among business users | |

| Wikis | A piece of server software that allows users to freely collaborate -- create and edit Web page content using any Web browser. |
| Virus | A virus is a malicious code or software designed to infect and potentially damage programs or files on a computer that receives it. It can spread to other users when the program or file is shared. |
| Hacking | Finding out weaknesses in a computer Seror computer network. |
| Firewall | A software program or hardware device used to prevent unauthorized access to your computer - it controls the incoming and outgoing network traffic by analyzing the data packets and determining whether they should be allowed through or not. |
| Router | Small physical devices that join multiple networks together. |
| NIC | (Network interface card) Computer hardware component that connects a computer to a computer network. |
| WAP | Wireless Access Point - a device that provides a location for wireless units to connect to a wired network using Wi-Fi, Bluetooth or related standards. The WAP usually connects to a router (via a wired network) if it's a standalone device. |
| Wired network | Can use Phone lines, power lines, ethernet to connect. (A network is two or more connected computers) |
| blog | A discussion or information site published on the World Wide Web consisting of "posts" typically displayed in reverse chronological order so the most recent post appears first. |
| Bluetooth connections | A wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions) |
| RAM | RAM (Random access memory) is a computer's short-term memory, storing data and program instructions. |
| ROM | ROM (Read only memory) is nonvolatile memory that contains the initial program running when the computer starts. |
