EE3010 Data Communications and LANs
Course Aims and Objectives: The aim of this course is to introduce the concepts, techniques, and structures of data communications; emphasises will be paid to local area networks. The objectives of this course include the introduction of necessary knowledge on different components in data communication systems; their structures, techniques as well as some common standards. In addition, examples of data networks are studied in the course. Units: 3 Level: B3 Medium of Instruction: English Syllabus: A simplified communication model Definition of data and information Computer communication protocols and architectures Protocol functions Simple 3-Layer example Motivation, concepts, terminology of OSI Reference Model Functions of the OSI layer Media - guided and unguided, point and multipoint Continuous and discrete signals, periodic signals, phase difference Relationship between data rate and bandwidth Data and signal - analog and digital Signal strength Transmission impairments - attenuation, delay distortion, noise channel capacity Guided transmission media - twisted pair, coaxial, optical fibre Unguided transmission media - microwave, satellite, radio Digital data, digital signals - NRZ, Multilevel Binary, Biphase Code Digital data, analog signals - ASK, FSK, PSK Analog data, digital signals - PAM, PCM A-law and u-law Analog data, analog signals - AM, FM Serial and parallel, asynchronous and synchronous transmission Error detection methods - parity, LRC, CRC Correction block codes Physical level protocols EIA-232-D Flow control - Stop-and-Wait, Sliding Window Error control - Stop-and-Wait ARQ, Go-Back-N ARQ, Selective Reject ARQ HDLC FDM, TDM, statistical TDM Network topologies - ring, bus and tree, star LLC (IEEE Std 802.2) Protocol - format, LLC/MAC interface CSMA/CD (IEEE Std 802.3) - format, operation, max throughput Fast Ethernet Token Ring (IEEE Std 802.5) - format, operation, max throughput Bridge Operation Routing with Bridges ii) Cisco Certified Network Associate (CCNA) – first module Teaching will be in the form of lectures with complementary tutorials and/or laboratory (laboratories). Tutorials will be informal, and may include a number of different support methods. For example: The laboratory support, if any, will complement the lecture and reinforce students’ understanding of the material. Teaching Pattern Total Hours: Lectures 26 hours (Group Size) Tutorials 8 hours (36) Laboratories 12 hours (27) Examination duration: 2 hours, at the end of the semester Percentage of coursework, examination, etc.: 15% CW; 15 % Laboratory For a student to pass the module, at least 30% of the maximum mark for the examination must be obtained, and a laboratory attendance of at least 75% recorded. Coursework should be based on several different exercises distributed over the period of the semester; examples include homework assignments, short test, mini projects and presentations.
