A type of LAN that does not use wires or cables to create connections, but instead transmits data over radio or infrared waves.
What is wireless LAN (WLAN)
100
A LAN in which all the devices are connected to a central hub.
What is star topology
100
A computer that handles a request for information or resources from a client computer.
What is server
100
An IP address available to the Internet.
What is public IP address
100
A device that amplifies signals on a network so they can be transmitted further down the line.
What is repeater
200
A repeater that is able to distinguish between noise and signal. It reads the signal and retransmits it without the accompanying noise.
What is signal-regenerating repeater
200
A server that acts as an intermediary between another computer and the Internet. The ______________ substitutes its own IP address for the IP address of the computer on the network making a request, so that all traffic over the Internet appears to be coming from only the IP address of the _____________.
What is proxy server
200
A cable that is made of one or more twisted pairs of wires and is surrounded by a metal shield.
What is shielded twisted-pair (STP) cable
200
A data encryption method for wireless networks that use the TKIP (Temporal Key Integrity Protocol) encryption method and the encryption keys are changed at set intervals while the wireless LAN is in use.
What is WPA (WiFi Protected Access)
200
A device used to segment a network. It can decide which network segment is to receive a packet, on the basis of the packet’s destination MAC address.
What is switch
300
A network topology in which the nodes in a network form a ring. Each node is connected only to two other nodes, and a centralized hub is not required.
What is ring topology
300
An IP address permanently assigned to a workstation
What is static IP address
300
An IP address that is used on a private TCP/IP network that is isolated from the Internet.
What is private IP address
300
A LAN that uses a logical bus design, but with all devices connected to a central hub, making a physical star.
What is star bus topology
300
A cable that is made of one or more twisted pairs of wires and is not surrounded by shielding.
What is unshielded twisted pair (UTP) cable
400
An older LAN technology developed by IBM that transmits data at 4 Mbps or 16 Mbps.
What is Token Ring
400
A data encryption standard compliant with the IEEE802.11i standard that uses the AES (Advanced Encryption Standard) protocol. WPA2 is currently the strongest wireless encryption standard.
What is WPA2 (WiFi Protected Access 2)
400
A topology that is physically arranged in a star formation but is logically a ring because of the way information travels on it. Token Ring is the primary example.
What is star ring topology
400
A connector used with twisted-pair cable that connects the cable to the NIC.
What is RJ-45 connector
400
The suite of protocols that supports communication on the Internet.
What is TCP/IP (Transmission Control Protocol/Internet Protocol)
500
A Microsoft resolution service with a distributed database that tracks relationships between NetBIOS names and IP addresses.
What is WINS (Windows Internet Naming Service)
500
Another term for an IBM Data Connector (IDC).
What is Universal Data Connector (UDC)
500
A _________________ is a group of four numbers (dotted decimal numbers) that tell TCP/IP if a remote computer is on the same or a different network.
What is subnet mask
500
A network or group of networks that span a large geographical area.
What is WAN (wide area network)
500
A data encryption method used on wireless networks that uses either 64-bit or 128-bit encryption keys that are static keys, meaning the key does not change while the wireless network is in use.
