- AP (Access Point) – see WAP
- DHCP (Dynamic Host Configuration Protocol) is a network management protocol used on TCP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks.
- DNS (Domain Name System) is a hierarchical decentralized naming system for computers, services, or other resources connected to the Internet or a private network. In other words, it is a system that transforms domain names into IP addresses.
- DSL (Digital Subscriber Line) is a family of technologies that are used to transmit digital data over telephone lines.
- Ethernet – 1. Wired computer network technologies commonly used in local area networks (LAN), metropolitan networks (MAN) and wide area networks (WAN). 2. Family of computer network protocols based on frame transmission and used in the implementation of LAN; specific to the first two levels of the OSI model.
- FTP (File Transfer Protocol) is the standard network protocol used for the transfer of computer files between a client and server on a computer network.
- Hotspot – physical location where Wi-Fi access is available.
- HTTP (Hypertext Transfer Protocol) is an application protocol for distributed, collaborative, and hypermedia information systems, being the foundation of data communication for the World Wide Web.
- ICMP (Internet Control Message Protocol) – protocol support in the Internet Protocol suite.
- IP (Internet Protocol) – is a protocol that provides a data transmission service without permanent connection.
- LAN (Local Area Network) is a computer network that interconnects computers in a limited area, such as a residence, school, laboratory, university campus, or office building.
- MAC (Media Access Control) is the layer that controls the hardware responsible for interacting with the wired, optical, or wireless transmission medium. The MAC address is a unique identifier assigned to a network interface controller (NIC) to be used as a network address in communications within a network segment. The MAC address is 48 bits long and is expressed in hexadecimal (12 digits).
- MAN (Metropolitan Area Network) is a computer network that interconnects users with computer resources in a geographic region the size of a metropolitan area.
- NAT (Network Address Translation) is a process by which IP packet header is changed to make the source or destination IP address in another.
- NIC (Network Interface Controller) NIC is a computer hardware component that connects a computer to a computer network.
- OSI (Open Systems Interconnection) – 1. Hierarchical communication protocol sets very often used to build a computer network. 2. Conceptual model that characterizes and standardizes the communication functions of a telecommunications or computing system, without taking into account the underlying internal structure and technology.
- PAN (Personal Area Networks) – Computer network for interconnecting electronic devices in a person’s workspace.
- RTD (Round-Trip Delay) – see RTT
- RTT (Round-Trip Time) is the time required for a signal to be sent plus the time required to confirm that that signal has been received.
- SMTP (Simple Mail Transfer Protocol) is an Internet standard for e-mail transmission.
- SNMP (Simple Network Management Protocol) – set of protocols for network management and monitoring.
- STP (Shielded Twisted Pair) is a type of shielded wiring in which two conductors of a single circuit are twisted together in order to improve electromagnetic compatibility.
- TCP (Transmission Control Protocol) – one of the main protocols of the internet protocol suite.
- TELNET – network protocol used in the Internet and in LAN computer networks for textual, bidirectional and interactive communication, based on making a virtual connection with the receiving workstation.
- TFTP (Trivial File Transport Protocol) – File transfer protocol, ensuring the transfer of files between processes.
- UTP (Unshielded Twisted Pair) is a type of unshielded wiring in which two conductors of a single circuit are twisted together in order to improve electromagnetic compatibility..
- VoIP (Voice over Internet Protocol) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.
- WAN (Wide Area Network) – computer network that spans a large geographical area for the main purpose of the computer network.
- WAP (Wireless Access Point) – network hardware device that allows other Wi-Fi devices to connect to a wired network; it can also be an integral part of a Wi-Fi router.
- W-LAN (Wireless LAN) – computer network of two or more devices using wireless communications to form a local area network (LAN).
