Network Administration
Final Exam
Course Introduction
Network Administration is a foundational course that introduces students to the principles and practices involved in managing computer networks. The course covers the configuration, maintenance, and troubleshooting of network hardware and software, emphasizing the skills needed to ensure secure and efficient network operations. Topics include network protocols, IP addressing, subnetting, network security fundamentals, server and client management, and the administration of network devices such as routers and switches. Through hands-on labs and real-world scenarios, students gain practical experience in network monitoring, performance optimization, and implementation of policies to maintain network reliability and security within an organizational environment.

Q1) Computer networks that use radio waves are termed ____________________ and can involve broadcast radio, microwaves, or satellite transmissions.
Answer: wireless
Q2) The OSI model consists of seven layers: application, presentation, session, ____________________, network, data link, and physical.
Answer: transport
Q3) What is data communications?
Answer: We will define data communications as the transfer of digital or analog data using digital or analog signals. Once created, these analog and digital signals then are transmitted over conducted media or wireless media. Both the data and the signal can be analog or digital, allowing for four possible combinations. Transmitting analog data by analog signals and digital data by digital signals are fairly straightforward processes-the conversion from one form to another is relatively simple. Transmitting digital data using analog signals, however, requires the digital data to be modulated onto an analog signal, which is what happens with a modem and the telephone system. Transmitting analog data using digital signals requires the data to be sampled at specific intervals and then digitized into a digital signal, which is what happens with a device called a digitizer, or codec.
