Voice over LTE (VoLTE) is a digital packet technology that uses 4G LTE networks to route voice traffic and transmit data.

Fiber optics, or optical fiber, refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic strand or fiber.

Network protocols are sets of established rules that dictate how to format, transmit and receive data so computer network devices -- from servers and routers to endpoints -- can communicate regardless of the differences in their underlying infrastructures, designs or standards.

A gigabit Ethernet phone, or gigE phone, is a VoIP telephone that connects to and uses gigabit Ethernet transmission technology to communicate with other phones.

A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system.

Pervasive computing, also called ubiquitous computing, is the growing trend of embedding computational capability (generally in the form of microprocessors) into everyday objects to make them effectively communicate and perform useful tasks in a way that minimizes the end user's need to interact with computers as computers.

Deep learning is a type of machine learning (ML) and artificial intelligence (AI) that imitates the way humans gain certain types of knowledge. At its simplest, deep learning can be thought of as a way to automate predictive analytics.

Dynamic spectrum access (DSA), also referred to as dynamic spectrum management (DSM), is a set of spectrum utilization techniques that adjusts frequency in real time based on fluctuating circumstances.

Wireline communication (also known as wired communication) is the transmission of information over a physical filament. Alternatively, communication technologies that transmit information over-the-air (OTA) are called wireless.

Interconnection is a strategy for ensuring that businesses can privately, securely and directly exchange digital information. An important goal of interconnection is to enable extremely high bandwidth exchanges with the lowest possible latency, at the lowest cost.

A storage area network (SAN) is a dedicated high-speed network or subnetwork that interconnects and presents shared pools of storage devices to multiple servers.

Coaxial cable is a type of copper cable specially built with a metal shield and other components engineered to block signal interference.

A local area network (LAN) consists of computers and peripherals that share a common communications line or wireless link to a server. LANs are typically located within a distinct geographic area in an office or other facility.

Routing Information Protocol (RIP) is a distance vector protocol that uses hop count as its primary metric.

Software-defined WAN (SD-WAN) is a technology to distribute network traffic across wide area networks (WAN) that uses software-defined networking (SDN) concepts to automatically determine the most effective way to route traffic to and from branch offices and data center sites.

nslookup is the name of a program that lets an Internet server administrator or any computer user enter a host name (for example, "whatis.com") and find out the corresponding IP address or domain name system (DNS) record.

Dynamic spectrum access (DSA), also referred to as dynamic spectrum management (DSM), is a set of spectrum utilization techniques that adjusts frequency in real time based on fluctuating circumstances.

Voice over LTE (VoLTE) is a digital packet technology that uses 4G LTE networks to route voice traffic and transmit data.

An IPv6 address is a 128-bit alphanumeric string that identifies an endpoint device in the Internet Protocol Version 6 (IPv6) addressing scheme. The new IP address format was created to enable the trillions of new IP addresses required to connect not only an ever-greater number of computing devices but also the rapidly expanding numbers of items with embedded computers in them.

Routing Information Protocol (RIP) is a distance vector protocol that uses hop count as its primary metric.

Software-defined networking (SDN) is a network architecture that aims to make data center networks agile and flexible.

A network switch is a hardware device that channels incoming data from multiple input ports to a specific output port that will take it toward its intended destination.

The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

A wireless access point (wireless AP) is a network device that transmits and receives data over a wireless local area network (WLAN). When a wireless device moves beyond the range of one AP, it is handed over to the next AP.

An application program interface (API) is code that allows two software programs to communicate with each other.

Telecommunications is the transmission of data, voice and video over significant distances by electronic means that use a wide variety of networks and media.

A SIM card, also known as a subscriber identity module, is a smart card that stores identification information that pinpoints a smartphone to a specific mobile network.

A call center is a centralized department to which phone calls from current and potential customers are directed.

A static IP address is a 32 bit number that is assigned to a computer to be its address on the internet.

Voice over LTE (VoLTE) is a digital packet technology that uses 4G LTE networks to route voice traffic and transmit data.

A gigabit Ethernet phone, or gigE phone, is a VoIP telephone that connects to and uses gigabit Ethernet transmission technology to communicate with other phones.

A wireless ad-hoc network (WANET) is a type of local area network (LAN) that is built spontaneously to enable two or more wireless devices to be connected to each other without requiring a central device, such as a router or access point.

A virtual private network (VPN) is programming that creates a safe, encrypted connection over a less secure network, such as the public internet. A VPN uses tunneling protocols to encrypt data at the sending end and decrypt it at the receiving end.

IoT security is the technology area concerned with safeguarding connected devices and networks in the internet of things (IoT).
