Computer Networking and Systems

The internet has become one of the most important components of our life. We browse the web, check e-mails, make VoIP phone calls, and have video conferences via computers. All of these applications are made possible by networking computers together, and this complex network of computers is usually referred to as the Internet. This course is designed to give you a clear understanding of how networks, from in-home local area networks, or LANs and WAN to the massive and global Internet, are built and how they allow us to use computers to share information and communicate with one another.

This course aim is to provide a sound conceptual grounding to computer networks, design principles and industrial practices. In this course, we will study the building scalable computer networks. We will go through the thought-process that went into designing the Internet—which is the best example of a computer network that has adapted and scaled to changing environment.

What you’ll learn

  • This courses address Local Area Networks (LANs), network definition using the OSI model, wired and wireless networks, Internet Protocol (IP), TCP/IP in the command line, networking services, wide area networks (WANs), and much more
  • Understanding Local Area Networks: Learn about local area networks (LANs) including network devices, data transfer, and types of LANs. Explore network topologies and access methods. Compare peer-to-peer and client/server network models.
  • Defining Networks with the OSI Model. ​Get to know the OSI model, and explore switches. Review the layers in the OSI and TCP/IP models, plus review different types of switches.
  • Understanding Wired and Wireless Networks including an overview of twisted-pair and fiber optic cables, and an overview of wireless devices and wireless networking standards.
  • Understanding Internet Protocol: Review IPv4 and IPv6. Review IPv4 address categories, default gateways, DNS servers, and subnetting.
  • Implementing TCP/IP in the Command Line: Basic and advanced TCP/IP commands.
  • Networking Services: Look at topics related to understanding common networking services and different name resolution techniques.
  • Understanding Wide Area Networks. Explore routers and WANs. See how routers function, including how data can be routed statically or dynamically, and learn how WANs are connected.
  • Learn about concepts of the Internet.
