HSC ICT Chapter 2 FAQ

Chapter 2 is Communication Systems and Networking (কমিউনিকেশন সিস্টেম ও নেটওয়ার্কিং). It explains how data moves between devices and how computers are connected to form networks.

Data communication is the exchange of data or information between devices through a transmission medium. The word communication comes from the Latin word communicare, which means to share.

The three data transmission methods are asynchronous, synchronous and isochronous transmission.

The common network topologies are bus, star, ring, mesh and tree. A topology describes how the computers and devices in a network are connected to each other.
