  1. COMMUNICATION MODES

  2. SIMPLEX • Simplex communication is a mode in which data only flows in one direction. • It is so because most modern communication require a two-way interchange of data and information on this mode of transmission is not as popular as it once was.

  3. HALF-DUPLEX • Half duplex data transmission means that data can be transmitted in both directions on a signal carrier, but not at the same time. • For example on a local area network using a technology that has half- duplex transmission, one workstation can send data on the line and immediately receive data on the wire from the same direction.

  4. Examples of half- duplex

  5. FULL- DUPLEX • The fastest directional mode of communication is full- duplex. • Here data is transmitted in both direction simultaneously on the same channel.

  6. ELECTRONIC COMMERCE • Electronic commerce, commonly known as [electronic marketing consists of the buying and selling of products or service over electronic systems such as the internet and other electronic systems. • Examples are: the internet and computers networks.

  7. NETWORKS • A network is a way of connecting several computers together. • So that they all have access to files, programs, printers, and other resource. • Networks solve the problems of information exchange and resource sharing. • Some types of networks are:

  8. LAN • Lan is also known as [ local area network]. • Computers that are within a few thousand feet of one another are physically connected with cables.

  9. WAN • Wan is also known [ wide area network] • Computers that are hundreds of miles apart and are connected by ‘ telephone’/ digital lines or satellites. • Computers that are hundreds of miles apart and are connected by "telephone"/digital lines or satellites

  10. NETWORKS

  11. BIBLIOGRAPHY • Firstly we would like to thank god for giving us the strength to complete this project successfully. • Information for this project on communication modes were taken from the internet.

  12. COMMUNICATION MODES This project on communication modes was done by: VIJAY RAMKISSOON AND STEFFON PRATICE.
