Gateway
In computer science, the gateway (GW) is a network node that serves as an access point
to another network, often involving not only a change of addressing, but also a different
networking technology. More narrowly defined, a router merely forwards packets
between networks with different network prefixes. In a home or small office
environment, the default gateway is a device, such as a router, that connects the local
network to the Internet. It serves as the default gateway for all network devices. ....................... 22
HF
High Frequency, the International Telecommunication Union (ITU) designation for the
range of radio frequency electromagnetic waves (radio waves) between 3 and 30 MHz. ............. 36
HTTP
In computer science, the Hypertext Transfer Protocol (HTTP) is an application layer
protocol in the Internet protocol (IP) suite model for distributed, collaborative,
hypermedia information systems. HTTP is the foundation of data communication for the
World Wide Web, where hypertext documents include hyperlinks to other resources
that the user can easily access, for example by a mouse click or by tapping the screen in
a web browser. ................................................................................................................................. 29
HW
Electronic hardware (HW) consists of interconnected electronic components which
perform analog or logic operations on received and locally stored information to
produce as output or store resulting new information or to provide control for output
actuator mechanisms. Well-designed electronic hardware is composed of hierarchies of
functional modules which inter-communicate via precisely defined interfaces. ............................ 38
IP address
In computer science, the Internet Protocol address (IP address) is a numerical label such
as 192.0.2.1 that is connected to a computer network that uses the Internet Protocol
for communication. An IP address serves two main functions - host or network interface
identification and location addressing. IP addresses are written and displayed in human-
readable notations, such as 192.0.2.1 in IPv4, and 2001 ................................................................. 22

LAN
In computer science, the local area network (LAN) is a computer network that
interconnects computers within a limited area such as a residence, school, laboratory,
university campus or office building. Ethernet (cable) and Wi-Fi (wireless) are the two
most common technologies in use for local area networks. ........................................................... 19
