| Question | Answer |
|---|---|
| client | a PC that requests information or services. |
| network interface card (NIC) | defines or labels on the network. |
| packets | small data unit |
| serevr | provides information or services. |
| bus topology | all computers connect to the network via a main line (bus cable) |
| ring topology | all computers on the network attach to a central ring of cable |
| star topology | where computers connect to a central wiring point(usually called a hub) |
| mesh topology | each computer has a dedicated line to every other computer |
| media access control (MAC) address | build-in identifier, a binary address unique to that single network card |
| cyclic redundancy check (CRC) | information is stored in the packet to enable the receiving network card to verify if the data was received in good order. |
| hardware protocol | defines everything necessary to get data from one computer to another. |
| Ethernet | Name coined by Xerox for the first standard of network cabling and protocols. Based on a bus topology. |
| 10BaseT | run at 10 Mbps |
| 100BaseT | run at 100 Mbps |
| 1000BaseT | runs at 1000Mbps or 1 Gbps |
| unshielded twisted pair (UTP) | composed of wired twisted around each other |
| hub | provides a common point of connection for network devices |
| switch | Device that filters and forwards traffic based on some criteria. A bridge and a router are both examples of switches. |
| bandwidth | capacity of a network transmit a given amount of data during a given period. |
| Shielded twisted pair (STP) | composed of wired twisted around each other and shielded. |
| full duplex | send and receive data at the same time |
| link lights | give you a clue about what is happening with the link |
| activity light | turns on when the card detects network traffic |
| coaxial cable | consist of a center cable (core) surrounded by insulation |
| client/server network | one machine is dedicated as a resource to be shared over the network |
| peer-to-peer network | enables any or all of machines on the network to act as a sever |
| domain-based network | one or more dedicated servers called (domain controllers) hold the security database for all systems. |
| directory service | store user and computer account information |
| administrator account | has complete an absolute power over the entire computer |
| NetBIOS Extended User Interface (NetBEUI) | default protocol for Windows for workgroups, Lantastic,a,nd Windows 95. |
| routers | sort packets and send them along the proper LAN |
| Transmission Control Protocol/Internet Protocol TCP/IP | Communication protocols developed by the U.S. Department of Defense to enable dissimilar computers to share information over the server |
| IP address | unique identification number for your system on the network |
| subnet mask | a value that distinguishes which part of the IP address is the network address and which part is the host address |
| destination port | a fixed, predetermined numebr that defines the function or session type |
| ephemeral port | an arbitrary number generated by the sending computer |
| PING | enables one machine to check whether it can communicate w/ another machine |
| default gateway | local router |
| domain name server (DNS) | keep databases of IP addresses and their corresponding names |
| dynamic host configuration protocol (DHCP) | enables you to create a pool of IP addresses that are given temporarily to machines. |
| static IP address | address will not change |
| loopback plug | device used during loopback tests to check female connector on a NIC |
