About this course
Computer networking impacts almost all aspects of our lives. Computer networks support the way we learn, communicate, play and work. Computer networking is an ever-evolving field with new technological advancements; network management can be a fun, exciting, and rewarding career path. Computer network administrators and security professionals are the ones who make sure computer systems run smoothly and seamlessly. They can install operating systems, configure networks and network management protocols, and manage network security. In this course, the fundamentals, protocols, and advanced networking concepts are dealt simply, deeply, and precisely. Understanding computer networking with OS-based networking commands, simulations using Cisco packet tracer and Wireshark packet sniffing tools are always engrossing and make learning interesting. The learner will find the following topics. 1. Fundamentals 1.1 Basic Characteristics of Computer Network. 1.2 Network Protocols and Communication. 1.3 Components of a computer network. 1.4 Classification of Computer Network: LAN, WAN, MAN, and SAN. 1.5 Network Topology: Bus, Star, Ring, Mesh, Hybrid. 1.6 Network Devices: Router, Switch, HUB, Bridge. 1.7 Circuit Switching vs Packet Switching networks. 1.8 The OSI Reference Model. 1.9 TCP/IP Model. 2.
