COM1006 Devices and Networks

Summary This module runs throughout the academic year, starting in Autumn and ending in Spring. The module consists of two parts. In the first, important elements of computer architecture are covered including digital logic, computer arithmetic and instruction set architecture. The approach in the module is to show how the basic elements of a computer are constructed and combined to give sophisticated architectures that support accelerated performance via cache memory and pipelining. The second half of the module shows how computing devices can be connected into networks, and covers the principles of layered protocols, error detection/correction and reliable transmission over networks.

Aims

The aims of this module are:

  1. To give the students an understanding of the underlying principles of number representations and arithmetic operations.
  2. To demonstrate how computing devices can be built from basic digital logic components, and how these can be optimised.
  3. To describe some conventional CPU architectures.
  4. To explain the principles of “Data Communication”
  5. To describe various types of network topologies
  6. To describe various categories of computer networks
  7. To explain the concept of “Internetworking”
Learning Outcomes  By the end of this module students should be able to:
  • Convert between different number representations, and recognise the strengths and weaknesses of different representations.
  • Demonstrate knowledge of digital logic, from digital algebra through to digital circuits
  • Identify and discuss standard computer processor architectures, and interpret assembly language programs for a simple processor architecture.
  • Explain the principles of wired and wireless computer networking, and mobile networks.
  • Discuss layered protocols for networking.
  • Describe principles of network addressing ( such as public and private address, Subnetting, supernetting )
  • Discuss the foundations of network and Internet security
