Lesson 1: Types of information transmission

Definition
Information Transmission can be defined as the process of sending, propagating and receiving of information from one person to another in the same remote or different location.  It can also be seen as a process of sending information or message from person to another or from one source to another source. 
TYPES OF INFORMATION transmission
Satellite: A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications.
Wireless: Wireless information transmission is wireless technology which transmit information from the source to the destination.
Wireless communication, or sometimes simply wireless, is the transfer of informationor power between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio waves. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. 
Somewhat less common methods of achieving wireless communications include the use of other electromagnetic wireless technologies, such as light, magnetic, or electric fields or the use of sound. 
Cable: A cable is two or more wires running side by side and bonded, twisted, or braided together to form a single assembly. The term originally referred to a nautical line of specific length where multiple ropes, each laid clockwise, are then laid together anti-clockwise and shackled to produce a strong thick line, resistant to water absorption, that was used to anchor large ships. In cable/wired transmission, the signal travels from one source to another via a cable. Some of the examples of transmission cable are:
Twisted Pair Cable
 Coaxial Cable 
Fiber Optic Cable.
