The choice between analog and digital transmission is a central theme in network design.

Progressing up the OSI model, the next unit explores how data is physically transmitted and framed for reliable delivery. It would cover various transmission media (guided media like twisted-pair, coaxial, and fiber-optic cables, and unguided media like radio waves and microwaves). This chapter also includes a discussion on network hardware like switches and Network Interface Cards (NICs), before moving to the data link layer’s functions: error detection and correction, and flow control techniques. The choice between analog and digital transmission is

A calculation where the sender sums data segments and appends the result to the packet; the receiver performs the same math to verify the values match. This chapter also includes a discussion on network

To optimize transmission paths and fit multiple signals onto a single medium, networks utilize modulation and multiplexing techniques. Digital Modulation Digital Modulation Example: A television broadcast or a
