- 47. (wide area network) A network that spans a long distance and connects two or more LANs.
- 49. (network interface card) The device that enables a workstation to connect to the network and communicate with other computers. NICs are manufactured by several different companies and come with a variety of specifications that are tailored to the workstation’s and the network’s requirements. NICs are also called network adapters.
- 50. The property of a network that allows you to add nodes or increase its size easily.
- 51. (Net+) The professional certification established by CompTIA that verifies broad, vendor-independent networking technology skills, such as an understanding of protocols, topologies, networking hardware, and network troubleshooting.
- 52. The process of distributing data transfer activity evenly so that no single device is overwhelmed.
- 53. The skills such as customer relations, oral and written communications, dependability, teamwork, and leadership abilities, which are not easily measured, but are nevertheless important in a networking career.
Down
- 1. The scheme for assigning a unique identifying number to every workstation and device on the network. The type of addressing used on a network depends on its protocols and network operating system.
- 2. A computer that manages Web site services, such as supplying a Web page to multiple users on demand.
- 4. A computer that enables resource sharing by other computers on the same network.
- 5. (Cisco Certified Network Associate) A professional certification that attests to one’s skills in installing, configuring, maintaining, and troubleshooting medium-sized networks that use Cisco Systems’ switches and routers.
- 6. The process of collecting and storing data on the number and types of software and hardware assets in an organization’s network. The data collection is automated by electronically examining each network client from a server.
- 8. The process of automatically transferring a data file or installing a software application from the server to a client on the network.
- 9. A discrete unit of information sent from one node on a network to another.
- 10. One of several types of specialized devices that allows two or more networks or multiple parts of one network to connect and exchange data.
- 12. The part of a network to which segments and significant shared devices (such as routers, switches, and servers) connect. A backbone is sometimes referred to as “a network of networks” because of its role in interconnecting smaller parts of a LAN or WAN.
- 14. (Cisco Certified Internetwork Expert) An elite certification that recognizes expert-level installation, configuration, management, and troubleshooting skills on networks that use a range of Cisco Systems’ devices.
- 16. A computer that uses applications and data only from its local disks and that is not connected to a network.
- 21. The process of retrieving files from a backup. It is necessary to restore files if the original files are lost or deleted.
- 25. A person who uses a computer.
- 28. The process of determining how much data transfer activity is taking place on a network or network segment and notifying administrators when a segment becomes overloaded.
- 31. See peer-to-peer network.
- 32. A network in which every computer can communicate directly with every other computer. By default, no computer on a peer-to-peer network has more authority than another. However, each computer can be configured to share only some of its resources and keep other resources inaccessible to other nodes on the network.
- 34. The network services that centrally administer and simplify complicated management tasks on the network. Examples of management services include license tracking, security auditing, asset management, address management, software distribution, traffic monitoring, load balancing, and hardware diagnosis.
- 35. The means through which data are transmitted and received. Transmission media may be physical, such as wire or cable, or wireless, such as radio waves.
- 36. The functions of a file server that allow users to share data files, applications, and storage areas.
- 37. The professional certification established by CompTIA that verifies knowledge about PC operation, repair, and management.
- 38. (metropolitan area network) A network that is larger than a LAN, typically connecting clients and servers from multiple buildings, but within a limited geographic area. For example, a MAN could connect multiple city government buildings around a city’s center.
- 41. A computer on the network that requests resources or services from another computer on a network. In some cases, a client could also act as a server. The term client may also refer to the user of a client workstation or a client software application installed on the workstation.
- 43. Unsolicited, unwanted e-mail.
- 45. network A network that uses centrally administered computers, known as servers, to enable resource sharing for and to facilitate communication between the other computers on the network.
- 46. A person working on a computer on a different network or in a different geographical location from the LAN’s server.
- 48. A standard method or format for communication between network devices. For example, some protocols ensure that data are transferred in sequence and without error from one node on the network to another. Other protocols ensure that data belonging to a Web page are formatted to appear correctly in a Web browser window. Still others encode passwords and keep data transmissions secure.
- 54. A part of a network. Usually, a segment is composed of a group of nodes that share the same communications channel for all their traffic.
