Cover page of Courseware ‘Basics in Data Communications – Part 1/3’

Book – Basics in Data Communications

The courseware “Basics in Data Communications” covers the topics of our 3-day seminar „Basics in Data Communications Technologies“.

WHY you should read the book:

This seminar is intended for all interested in basics in data communications technologies used in Local Area Networks (LAN) and Wide Area Networks (WAN).

Part 1/3 covers basic terms of the large field of information and communication technologies and the Open Systems Interconnection (OSI) model specified by the International Organization for Standardization (ISO).

Part 2/3 covers Local Area Networks (LANs). Typical features, topologies, cabling options, media access procedures, Ethernet, WLAN and higher layer protocols are covered.

Part 3/3 covers Wide Area Network (WAN) switching technologies, important network elements, WAN services and data communication in public mobile radio networks.

The courseware in book format contains the MS Powerpoint slides in notes view and additional explanations.

Use the courseware for your self-paced learning or as handout for your presentations.
