Eng 2139 Ch03 Fundamentals Of Data Networks Part 1 Pdf This document discusses data communication and computer networks. it introduces the basic elements of a communication system including a sender, medium, and receiver. For data communications to occur, the communicating devices must be part of a communication system made up of a combination of hardware (physical equipment) and software (programs). A virtual circuit network is normally implemented in the data link layer, while a circuit switched network is implemented in the physical layer and a datagram network in the network layer. Network security issues include protecting data from unauthorized access, protecting data from damage and development, and implementing policies and procedures for recovery from breaches and data losses.
Chapter 5 Data Communication Computer Network Internet And Computer A virtual circuit network is normally implemented in the data link layer, while a circuit switched network is implemented in the physical layer and a datagram network in the network layer. Network security issues include protecting data from unauthorized access, protecting data from damage and development, and implementing policies and procedures for recovery from breaches and data losses. Show clear understanding of the basic concepts of data communications including the key aspects of networking and their interrelationship, packet switching, circuit 1 switching and cell switching as internal and external. Data transmission modes communication between two devices can be simplex, half duplex, or full duplex.
