__**Definitions**__ 1. __Software__: The programs, routines, and symbolic languages that control the functioning of hardware and direct its operation, It describes any electronic media content, which can be in a form of a film, tape, or record and it usually performs a productive task for the user. 2. __Template__: A computer based information retreival system that enables a user to gain \or provide acess to texts, audio and video recording, photographs and computer graphics related to a particular subject and is an extension of the term "hypertext" which is simply text on a computer. 3. __Database Management System__: is a computer software designed for the purpose of managing a structured collection of records known as a "database". For example, oracle, DB2, Microsoft Access, Microsoft SQU server, amongst others are examples because they are complex setx of stoftware systems that control the organization and storage of data. 4. __Spell Check__ is a program designed to ensure the correct spelling of words, and are either stand alone applications capable of operating on a block of text or as a feature of a larger application like word processor, email client, electronic dictionary, or search engine. 5. __Mp3__ is an audio encoding format taht uses a lossy compression algorithm, that is used to reduce the amount ofdata used to re present the audio recording. The compression works by removing certain parts of sound,it provides a representation of pulse- code modulation— encoding audio in much less space than straightforward methods, by using psychoacoustic models to discard components less audible to human hearing, and recording the remaining information in an efficient manner

__**Identifications**__ 1. __Template:__ In computers it is an electronic file with a predesigned, customized, format and structure. As for a fax, letter, or expense report ready to be filled in. 2. __Simulation__ in a computer is an attempt to model a real life hypothetical situation, in many cases so that it can be studied. 3. A __Key field__ is a field or set of fields of a database (typically a relational database) table which together form a unique identifier for what is known as a database record (or a table entry). The collection of these fields is usually referred to simply as "the key". A Key fields also define searches 4. __Freeware__ is copyrighted computer software which is made available for use free of charge, for an unlimited time. Authors of freeware often want to "give something to the community", but also want to retain control of any future development of the software. It is a different form of shareware, since the user does not have to pay unlike in shareware. 5. __Database__ is a structured collection of records or data that is stored in a computer system so that a computer program or person using a query language can consult it to answer queries. (The records retrieved in answer to queries are information that can be used to make decisions). In simple terms it is a collection of related records, and its software is known as a database management system (see above).

Server: Can refer to the machine that stores files of many users and programs that can be shared, or to the program that allows communication with a browser. In our school we have a server. A server is different than a network because on a network users are connected to one another while on a server files are shared with users.

Access Permissions: Are certain rights a user or individual has to opening a file or folder. If a user does not have certain privledges they are not aloud to extract or open a certain folder/file. Access Permissions are different from passwords in that if a file is password protected then you must a certain password to attain the file but in Access Permissions if you are not granted permission by an Administer than you cannot open a file, in Access Permissions the folder/file does not need a password

Login: If you wish to access a network, server, or a computer you are prompted with a login which will most likely ask for a username and password.

LAN: Local Area Network. A network of mulitple computers either in a home, small office, or multiple buildings. LAN differs from WAN because WAN is a world-wide network.

WAN: World Area Network. A network of thousands of computers that are connected gloabally. Differs from LAN in that LAN is a smaller version of a WAN and has a fewer amount of computers.

SysAdmin: System Administrator(Heyyyyy Shantanu thats you) A SysAdmin is responsible of a companys network in which they manage the network. A SysAdmin gives access permissions to people on the network and limits users from gaining access to certain files/folders

RAM: Random Access Memory, Type of computer memory. RAM is used for a computers short term memory. RAM is gone if a computer is shut down or restarted. For example if you are typing something and you accidentaly delete it, if you wish to undo your computer accesses your RAM and brings back your work in a sense. Differs from ROM in which ROM is not lost when the computer is shut down or restarted.

ROM: Read only memory. ROM is memory that can be accessed and read but cannot be changed. ROM is non-volitile while RAM is volitale and will be erased when the computer is shut off while when the computer is shut off ROM is not destroyed.

GB: Gigabyte is 1024 megabytes and is approximately 1000 mb. A gigabyte is a unit of measurement in the world of computers.

Compatibility: When you buy hardware and wish to upgrade your computer, you must find out whether your new hardware is compatible with your computer. Your computer must be able to recognize and read the hardware to fully function with it. Compatibility also reffers to Software and Application because before buying software you must read the System Requirments to find out if the Software is compatible with your Operating System.

Key Terms:

Define (5 Terms):

Internet Protocol (IP): The Internet Protocol (IP) is a data-oriented protocol used for communicating data across a packet-switched internetwork. IP can be used over a heterogeneous network for example a network connecting two computers can be any mix of Ethernet, ATM, FDDI, Wi-Fi, token ring, etc.

Cookies: HTTP cookies are parcels of text sent by a server to a web browser and then sent back unchanged by the browser each time it accesses that server. HTTP cookies are used for authenticating, tracking, and maintaining specific information about users, such as site preferences or the contents of their electronic shopping carts.

URL: Abbreviation of Uniform Resource Locator, the global address of documents and other resources on the World Wide Web. The first part of the address indicates what protocol to use, and the second part specifies the IP address or the domain name where the resource is located.

Hyperlink: An element in an electronic document that links to another place in the same document or to an entirely different document. Typically, you click on the hyperlink to follow the link. Hyperlinks are the most essential ingredient of all hypertext systems, including the World Wide Web.

Intranet: A network based on TCP/IP protocols (an internet) belonging to an organization, usually a corporation, accessible only by the organization's members, employees, or others with authorization. An intranet's Web sites look and act just like any other Web sites, but the firewall surrounding an intranet fends off unauthorized access. Like the Internet itself, intranets are used to share information. Secure intranets are now the fastest-growing segment of the Internet because they are much less expensive to build and manage than private networks based on proprietary protocols.

Identify (5 Terms):

WebCam: Also called an IP camera, a network camera records images and sends the compressed versions over the network. Network cameras used in surveillance systems usually offer a browser interface so the camera can be remotely accessed and viewed over the Internet. Network Video Recorder (NVR) systems use network cameras.

Search Engine: A [|program] that searches documents for specified [|keywords] and returns a list of the documents where the keywords were found.

E-mail: Short for electronic mail, the transmission of messages over communications networks.

Teleconferencing: To hold a conference via a telephone or network connection.

Videoconferencing: Conducting a conference between two or more participants at different sites by using computer networks to transmit audio and video data.
