Internet, Extranet, Intranet

Email, Simple Mail Transfer Protocol (SMTP) (Read Terminology, Origin, Operation).

Local Area Network. Router: definition, Operation, Application. Switch: Layers 1, 2, 3. Firewall. Network Interface Card (NIC) is a hardware component, typically a circuit board or chip, which is installed on a computer so that it can connect to a network.

Scalability, the ability of a computing process to be used or produced in a range of capabilities (Oxford Dictionary). Server farm.

Network Transmission Media: Twisted Pair (Read definition, Explanation and Unshielded Twisted Pair (UTP)). Coaxial Cable (Read definition and Applications) Optical Fiber (read definition, Communication, Advantages Over Copper Wire).

10Base-T, one of several physical media specified in the IEEE 802.3 standard for Ethernet local area networks (LANs), is ordinary telephone twisted pair wire. 10Base-T supports Ethernet's 10 Mbps transmission speed.

Bandwidth: The maximum amount of data transmitted over an internet connection in a given amount of time.

Wireless: Wi-Fi. Bluetooth. WiMAX is a telecommunication and mobile technology used for broadcasting of wireless data by the use of a number of transmission methods. WiMAX stands for Worldwide Interoperability for Microwave Access ... The WiMAX network is just like a cell phone. Intel made a big investment, but the technology was not adopted for the phone network.

Backbone: A backbone can tie together diverse networks in the same building, in different buildings in a campus environment, or over wide areas. Normally, the backbone's capacity is greater than the networks connected to it. A large corporation that has many locations may have a backbone network that ties all of the locations together, for example, if a server cluster needs to be accessed by different departments of a company that are located at different geographical locations.

Packet and Circuit Switching.

Multiplexing:

Time Division: Computers A and B split their messages into packets and share the transmission medium by taking turns sending the data.

Frequency Division: Computers A and B split the frequency: A uses a higher spectrum. By listening only to the assigned frequency, multiple transmissions can occur at the same time.

Spread Spectrum: Sharing a medium by both frequency and time is one method

of spread spectrum transmission. It is efficient for many computers because the full bandwidth can be utilized over time and frequency.

Network neutrality, or simply net neutrality, is the principle that Internet service providers (ISPs) must treat all Internet communications equally, and not discriminate or charge differently based on user, content, website, platform, application, type of equipment, source address, destination address, or method of communication.

From Federal Communications Commission: The FCC's Restoring Internet Freedom Order, which took effect on June 11, 2018, provides a framework for protecting an open Internet while paving the way for better, faster and cheaper Internet access for consumers. (This page has been removed)

TCP/IP Reference model - Internet protocol suite. Key architectural principles, Link layer, Internet layer, Transport layer, Application layer. The TCP/IP model has recently been updated to five layers, so the bottom four layers are the same as in the OSI model. Not in Wikipedia yet.

ISO-OSI Reference Model or OSI Model. Layer architecture: Physical layer, Data Link layer, Network layer, Transport layer, Session layer, Presentation layer, Application layer. Media Access Control (MAC) address.

Internet Services: The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network. FTP is built on a client-server model architecture using separate control and data connections between the client and the server.

The World Wide Web (WWW), commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators (URLs, such as https://www.example.com/), which may be interlinked by hypertext, and are accessible over the Internet. The resources of the WWW may be accessed by users by a software application called a web browser.

Voice over IP: Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. Some VoIP services may only allow you to call other people using the same service, but others may allow you to call anyone who has a telephone number - including local, long distance, mobile, and international numbers. Also, while some VoIP services only work over your computer or a special VoIP phone, other services allow you to use a traditional phone connected to a VoIP adapter. (From FCC)

Internet Addresses: IP (Internet Protocol) Address, IPv4 and IPv6. Dynamic Host Configuration Protocol (DHCP). Internet Service Provider (ISP).

Internet 2 operates the nation’s largest and fastest, coast-to-coast research and education network that was built to deliver advanced, customized services that are accessed and secured by the community-developed trust and identity framework, with Internet2 Network Operations Center powered by Indiana University.

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. The definition of the Internet of things has evolved due to the convergence of multiple technologies, real-time analytics, machine learning, commodity sensors, and embedded systems.

Traditional fields of embedded systems, wireless sensor networks, control systems, automation (including home and building automation), and others all contribute to enabling the Internet of Things. In the consumer market, IoT technology is most synonymous with products pertaining to the concept of the "smart home", covering devices and appliances (such as lighting fixtures, thermostats, home security systems and cameras, and other home appliances) that support one or more common ecosystems, and can be controlled via devices associated with that ecosystem, such as smartphones and smart speakers.
