Terms in this set (47)
repeater or hub
An electronic device that receives a network signal in the form of bits, cleans it of unnecessary noise, and regenerates it.
Have replaced hubs in local area networks.
bridge or switch
A device that connects and filters multiple network segments or devices, by forwarding data only to one or multiple devices that need to receive the data based on destination MAC address.
A device that forwards data packets between different computer networks based on network address (IP address).
A device used to connect network nodes via wire not originally designed for digital network traffic, by modulating the digital signal to produce an analog signal for transmission.
A device used to control network security and access rules by rejecting access requests from unrecognized sources while allowing actions from recognized ones.
A device that allows wireless devices to connect to a wired network using Wi-Fi, or related standards.
The size of an IPv4 address.
The size of an IPv6 address.
An IPv4 address.
An IPv6 address.
IP addresses are manually assigned to a computer by an administrator.
IP addresses assigned either by the computer interface or host software itself through automatic configuration, or assigned by a server using DHCP.
A computer resource made available from one host to other hosts on a computer network.
A network environment in which each computer is responsible for its own security, rather than relying on centralized authentication.
An option on Windows 7 and later Microsoft operating systems that extends the workgroup by using a password to join computers into the group, and allows users' libraries, along with individual files and folders, to be shared between multiple computers.
The centralized authentication approach used in larger networks, where all user accounts, computers, printers and other security principals, are registered with a central directory service.
The amount of information that can be sent through a given communication channel in a given amount of time.
A discussion or informational site published on the World Wide Web and consisting of discrete entries ("posts") typically displayed in reverse chronological order (the most recent post appears first).
A wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs).
A wide bandwidth data transmission with an ability to simultaneously transport multiple signals and traffic types.
Describes any form of electronic conferencing, but traditionally refers to synchronous text-based communications with a group of users.
A piece of computer hardware or software that accesses a service made available by a server.
To receive data to a local system from a remote system, or to initiate such a data transfer.
A family of computer networking technologies for local area networks (LANs) and metropolitan area networks (MANs), standardized in 1983 as IEEE 802.3.
A computer attached to a network that has the primary purpose of providing a location for shared storage of computer files that can be accessed by workstations attached to the same computer network.
An online discussion site where people can hold conversations in the form of posted messages.
global positioning system (GPS)
A space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the earth where there is an unobstructed line of sight to four or more GPS satellites.
instant messaging (IM)
A type of online chat which offers real-time text transmission over the Internet.
local area network (LAN)
A computer network that interconnects computers within a limited geographic area such as a home, school, computer laboratory, or office building.
A network topology in which each node relays data for the network.
An individual responsible for the maintenance of computer hardware and software systems that make up a computer network.
network adapter (NIC)
A computer hardware component that connects a computer to a computer network.
network operating system (NOS)
Software that implements an operating system of some kind that is oriented to computer networking.
A digital networking communications method that groups all transmitted data into suitably sized blocks, called packets, that are transmitted via a medium that may be shared by multiple simultaneous communication sessions.
peer-to-peer (P2P) protocol
An application layer distributed networking protocol that can be used to form and maintain an overlay network among participant nodes.
A system of rules that allow two or more entities of a communication system to communicate between them to transmit information via any kind of variation of a physical quantity.
Radio-frequency identification (RFID)
The wireless use of electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects.
The computer networking model and set of communications protocols used on the Internet and similar computer networks.
The exchange of information between two or more entities using technology in the form of signals over a physical medium or in the form of electromagnetic waves.
A brief, electronic message sent between two or more mobile phones, or fixed or portable devices over a phone network.
A type of wiring in which two conductors of a single circuit are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources.
The sending of data from a local system to a remote system such as a server or another client with the intent that the remote system should store a copy of the data being transferred, or the initiation of such a process.
virtual private network (VPN)
A private, secure path over the Internet that provides authorized users a secure means of accessing a private network via the Internet.
wide area network (WAN)
A network that covers a broad geographic area using leased telecommunication lines.
A local area wireless computer networking technology based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards.
wireless local area network (WLAN)
Links two or more devices over a short distance using a wireless distribution method.
