INTERNET TECHNOLOGY
TRANSMISSION MEDIA
INFRARED is a wired transmission media that sends signals using infrared light waves. It is used for short range communication. (eg; mouse, printer, smart phone)
CELLULAR RADIO is a form of broadcast radio that used widely for mobile communication, specifically wireless modems and cell phones. A cell phone is a device that uses high-frequency radio waves to transmit voice and digital data messages.
BROADCAST RADIO is a wireless transmission medium that uses radio waves to send signals through the air. It can operate over long distances and short distances. It requires a transmitter and receiver, making it slower and more prone to noise.
MICROWAVES provides high-speed signal transmission using microwave frequencies, often referred to fixed wireless. It can transmit data at rates up to 4,500 times faster, enabling high- speed communication. Commonly used in wide open areas and remote or rural areas.
COMMUNICATION SATELLITE is a space station that receives microwaves signals from an earth-based station, amplifies the signals, and broadcasts the signal back over a wide area, (eg; GPS receiver as earth-based station). Uplink transmission usually slower than downlink transmission.

COMMUNICATION DEVICES
HUB/SWITCHES is device that provides a central point for cables in a network. It receives data from many directions then forward it to one or more destinations
WIRELESS ACCESS POINT is a central communication device that allows computers and devices to transfer data wirelessly among themeselves or to transfer data wirelessly to wired network
WIRELESS MODEM is a communication devices that uses a mobile service providers network to connect to the internet wirelessly from a computer or mobile devices
NETWORK CARD is a communication device that enables a computer or device that does not have built-in capability to access a network
ROUTER is a communication device that enables a computer or other routers together and transmits dta to its correct destination on a network, sending data packets from receiving computer and direct the traffic of a network
DIAL-UP MODEM is a communication device that converts digital signals to analog signals vice versa so that can travel along an analog phone line
DIGITAL MODEM is a communication device that sends and receives data and information to and from a digital line. eg:cabe modem,DSL modem
CONCEPT OF NETWORK
Network is a collection of computers and devices connected together via communication devices and transmission media
