Terms in this set (48)
A network that creates a point-to-point connection between locations that remains open for the duration of the communication.
Public Switched Telephone Network (PSTN)
The worldwide network of circuit-switched telephone lines.
A network that transfers data by breaking it up into separately transferred packets.
A global packet-switched network created cooperatively by multiple companies, governments, and standards organizations.
A rule or custom that governs how something is done. In a computer context, it refers to a standard for transferring data.
Internet Service Provider (ISP)
A company that maintains a direct connection to the Internet and leases access to it to individuals and companies.
A related group of protocols-for example, TCP/IP.
The protocol suite (set of rules) that defines how data will move on the Internet and on most other modern networks.
Virtual Private Networking (VPN)
A method of creating a secure, private communication tunnel using a public communications channel such as the Internet.
A data transmitter/receiver in geosynchronous orbit with the Earth.
A cellular phone that includes computer applications and Internet access capability.
To connect a smartphone to a computer so that the computer can use the smartphone's Internet access.
Personal Area Network (PAN)
A network formed when devices are connected to an individual computer.
Local Area Network (LAN)
A network that connects devices housed in the same physical location.
Metropolitan Area Network (MAN)
A network that connects devices within the area of a city or town.
Wide Area Network (WAN)
A network that spans at least two or more offices may have a LAN at each site but use a WAN to connect them all to the same network.
Peer-to-Peer (P2P) Network
A network that consists only of clients (no servers).
A network that contains one or more servers.
A computer used by an individual to run applications.
A special network that only staff within the company network can access. For security reasons, an intranet can only be accessed onsite and not remotely.
A special network set up by a business for its customers, staff, and business partners to access from outside the office network; may be used to share marketing assets and other non-sensitive items.
The current dominate standard for local area networking devices.
A type of Ethernet that transfers data at up to 1000 Mbps over twisted-pair cables.
Wireless Ethernet. A means of connecting computers and other devices wirelessly. Another name for it is IEEE 802.11, its technical standard.
An inexpensive short-range networking technology used for computer-to-device connections such as computer-to-printer or phone-to-headset.
To connect a Bluetooth input or output device to a computer.
Older type of wireless communication that used light waves to pass simple information between nearby devices.
Microwave Communication System
A secure, point-to-point wireless networking technology that requires a line of sight between the two points.
A hardware component that enables a computer to connect to a network.
Network Interface Card (NIC)
A network adapter that is on an expansion card, rather than built into the computer's motherboard. Sometimes used informally to refer to any network adapter.
Media Access Control (MAC) Address
A unique hardware address for a network adapter.
A gathering point for the computers in a LAN to connect with to participate in the network.
Wireless Access Point (WAP)
A wireless switch.
A primitive version of a switch that lacks the capability to read packet addresses and route them to the appropriate port.
A connection box for Ethernet networks that physically joins the devices in the network (wired) or provides wireless connectivity (wireless), and enables a connection to an outside network such as the Internet.
The port on a router that connects to external networks.
A connector box that enables you to connect two dissimilar networks.
A connector box that enables you to connect two networks of similar types.
A device that receives and retransmits a network signal.
Cable that transfers data via pairs of copper wires that are twisted around each other to reduce electromagnetic interference.
Electromagnetic Interference (EMI)
The corruption of data as it is passing through a cable due to the magnetic field generated by a nearby cable.
Unshielded Twisted Pair (UTP)
A type of twisted-pair cable that does not have an outer sheath that protects against external EMI.
Shielded Twisted Pair (STP)
A type of twisted-pair cable that has an outer sheath that protects against external EMI.
Category 3 Cable
A type of UTP cable used in telephone systems.
A connector used on one-line UTP telephone cables.
A connector used on two-line UTP telephone cables.
Category 5e Cable
A type of UTP cable used in 1000BaseT Ethernet networking.
