Introduction to Networking Exam Materials
Course Introduction
Introduction to Networking provides students with a foundational understanding of computer networks, covering essential concepts such as network topologies, protocols, data transmission methods, and the OSI and TCP/IP models. The course explores both wired and wireless networks, Ethernet technology, IP addressing, and the basics of routing and switching. Students will also learn about network devices including switches, routers, and hubs as well as network security principles and troubleshooting techniques. Through practical examples and hands-on labs, the course equips learners with the skills needed to understand, set up, and maintain basic networks in both personal and professional environments.

Sample Questions
Q1) Define a checksum and describe how Transport layer protocols implement them to ensure data integrity.
Answer: To ensure data integrity further, connection-oriented protocols such as TCP use a checksum. A checksum is a unique character string that allows the receiving node to determine if an arriving data unit exactly matches the data unit sent by the source. Checksums are added to data at the source and verified at the destination. If at the destination a checksum doesn't match what the source predicted, the destination's Transport layer protocols ask the source to retransmit the data.
