Twister Pair Cable

made up of copper wires that are twisted around each other and surrounded by a plastic jacket

Coaxial Cable

insulated copper wire; used to carry high-speed data traffic and television signals

Fiber Optic Cable

A cable that transmits data at close to the speed of light along glass or plastic fibers.

Netwrok protocols

set of rules and procedures that nodes a network must follow to communicate with one another

Transmission Control Protocol(TCP)

A protocol for sending packets that does error-checking to ensure all packets are received and properly ordered

Internet Protocol (IP)

a protocol for sending data across the Internet that assigns unique numbers (IP addresses) to each connected device

Application Layer

The seventh layer of the OSI model. Application layer protocols enable software programs to negotiate formatting, procedural, security, synchronization, and other requirements with the network.

Transport Layer

The fourth layer of the OSI model. In this layer protocols ensure that data are transferred from point A to point B reliably and without errors. this layer services include flow control, acknowledgment, error correction, segmentation, reassembly, and sequencing.

Internet Layer

responsible for addressing, packaging, and routing messages on the Internet

Network Interface Layer

responsible for placing packets on and receiving them from the network medium

Client/Server Computing

Form of distributed processing in which some machines (servers) perform computing functions for end-user PCs (clients).

Peer-to-Peer Processing (P2P)

A type of client/server distributed processing that allows two or more computers to pool their resources, making each computer both a client and a server.

wireless

telecommunications in which electromagnetic waves carry the signal between communicating devices

mobile

capable of moving or being moved

Dematerialization

The process in which fewer materials are used in the creation of a product

microwave

very short electromagnetic wave

Radio Waves

Electromagnetic waves with the longest wavelengths and lowest frequencies

satellite transmission

a wireless transmission system that uses satellites for broadcast communications

Short-Range Wireless Networks

Bluetooth

Ultra-Wideband

Near-Field Communications

Medium-Range Wireless Networks

the familiar wireless local area networks (WLANs) and the most common type of Medium-Range network is wireless fidelity (Wi-Fi).

Wide Area Network (WAN)

Spans a large geographic area such as a state, province, or country

Mobile Computing

A real-time connection between a mobile device and other computing environments, such as the Internet or an intranet.

Mobile Commerce

Internet channels accessed through tablets, smartphones, or other handheld devices. Also known as mobile marketing, m-commerce, or mobile retailing.

source data automation

The collection of transaction data in machine-readable form at the time and place of origin. Examples are point-of-sale terminals and ATMs.

Sensors

Input devices used to measure physical traits, such as sound, heat, or light.

Rapid Frequency Identification (RFID)

a wireless technology that uses radio waves to track, identify, and manage objects, animals, or people

Internet of Things (IoT)

the network of products embedded with connectivity-enabled electronics

Cloud Computing

the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

server virtualization

a server computer hosts one or more other server computers

Infrastructure as a Service (IaaS)

delivers hardware networking capabilities, including the use of servers, networking, and storage, over the cloud using a pay-per-use revenue model

PaaS (Platform as a Service)

A service model in which various platforms are provided virtually, enabling developers to build and test applications within virtual, online environments tailored to the specific needs of a project.

Software as a Service (SaaS)

A form of cloud computing where a firm subscribes to a third-party software and receives a service that is delivered online.

Security as a Service (SECaaS)

Provides your organization with various types of security services without the need to maintain a cybersecurity staff

Function as a Service (FaaS)

A cloud service model that supports serverless software architecture by provisioning runtime containers in which code is executed in a particular programming language
