| Brief description of the Unit |
This unit will provide students with an understanding of the network technologies, protocols and security considerations for distributed computing environments and equip them with skills necessary for computer network design. The unit covers computer networking and its security encompassing Local Area Networks (LANs), Metropolitan Area Networks (MANs) and Wide Area Networks (WANs) together with the underlying network protocols that form the backbone of today's Internet. It also covers the Quality of Service (QoS) requirements of different types of applications and how network protocols handle QoS issues. |
