1 Section 2 terms -Savannah Gray

2 Network- a computer network or data network is a telecommunications network which allows computers to exchange data. A group of computer connected together to exchange data. Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include anchors such as personal computers, phones, servers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. Computer networks differ in the transmission medium used to carry their signals, the communications protocols to organize network traffic, the network's size, the way in which parts are arranged, and organizational intent. Local area network (LAN)- a computer network that links devices within a building or group of adjacent buildings. Mrs. Bowser’s Room is a LAN. Network software- software-defined networking (SDN) is an approach to computer networking that allows network administrators to manage network services through abstraction of lower-level functionality. Networking software applications are available to manage and monitor networks of all sizes, from the smallest home networks to the largest enterprise networks. Networking

3 WiFi is the one of the most common transmission technologies in use for local area networks.
Wireless local area network- a wireless local area network (WLAN) is a wireless computer network that links two or more devices using a wireless distribution method (often spread- spectrum or OFDM radio) within a limited area such as a home, school, computer laboratory, or office building. Wireless LANs have become popular for use in the home, due to their ease of installation and use. They are also popular in commercial complexes that offer wireless access to their customers. WiFi

4 Operation Operating environment- the environment in which users run application software. An operating environment is usually not a full operating system but is a form of middleware that rests between the operating system and the application. EX; Microsoft Windows, Windows 1.0 (not a full operating system) Operating system- the software that supports a computer's basic functions, such as scheduling tasks, executing applications, and controlling peripherals. (examples: iOS 10 for iPhone and Marshmallow for Android phones).

5 STORAGE Magnetic storage media- the storage of data on a magnetized medium; hard disks, widely used to store computer data. (hard drive). Storage- the action or method of storing something for future use.

6 Compact disc CD-ROM (compact disc read-only memory) - an adaptation of the CD that is designed to store computer data in the form of text and graphics. The original data format standard was defined by Philips and Sony in the Yellow Book. CD-R (compact disc recordable) - a type of write once, read many (WORM) compact disc (CD) format that allows one-time recording on a disc. The CD-R, originally named CD Write-Once, first published in 1988 by Philips and Sony in the 'Orange Book'.

7 miscellaneous Multitask- the simultaneous execution of more than one program or task by a single computer processor. Boot process- the heart of a modern computer is one or more Central Processing Units. A CPU gets its instructions from memory. The CPU reads instruction from the BIOS and searches for the hard disks, CD drives and other hardware. The BIOS program looks at the first sector for boot code. Logging in/logging on- the process by which an individual gains access to a computer system by identifying and authenticating themselves.

8 miscellaneous - electronic mail is a method of exchanging digital messages between computer users. Protocol- the official procedure or system of rules governing affairs of state or diplomatic occasions. A common set of rules and instructions that each computer follows. A specific set of communication rules is called a protocol. Data- facts and statistics collected together for reference or analysis.

9 miscellaneous Router- a networking device that forwards data packets between computer networks. Malware- to refer to a variety of forms of hostile or intrusive software, including computer viruses, worms, ransom ware, spyware, adware, scare ware, and other malicious programs. Virus- a type of malicious software program ("malware") that, when executed, replicates by reproducing itself or infecting other computer programs. Channel- a band of frequencies used in radio and television transmission, especially as used by a particular station.
