Paper Structure

As an introductory paper to data communications and computer networks, this paper consists of three parts.

The first part covers the fundamental aspects of data communications, including:

• Transmission media
• Signals and encoding
• Modulation
• Multiplexing
• Data compression
• Error detection and correction
• Security
• Protocols

The second part covers the topics of computer networks, including:

• The Open Systems Interconnect (OSI) model
• Local Area Networks (LANs) and their IEEE standards
• Flow and error control
• Wide Area Networks (WANs)
• Routing algorithms
• Congestion control
• Transport services

The third part covers the principles of the Internet, including:

• The TCP/IP reference model
• The Internet Protocol (IP) suite
• Various Internet applications
• IPv6

Some advanced topics, such as wireless networking and computer ethics are also covered in the paper.
