Network Programming

Course Title: Network Programming (3 Cr.)
Course Code: CACS355
Year/Semester: III/VI
Class Load: 5 Hrs. / Week (Theory: 3Hrs. Practical: 2 Hrs.)

Course Description 

This course is designed to extend students’ knowledge and practice in analysis and design of computer networks by focusing on computer network programming. It includes introduction, Internet Address, URLs and URIs, HTTP, URL Connections, Socket Programming, IP Multicast and RMI.

The JAVA programming language will be used throughout the course. it does not entirely focus on theoretical concept but also strongly focuses on practical skill based knowledge.

Course objectives 

The general objectives of this course are to provide theoretical as well as practical knowledge of network programming to make students capable of developing, implementing, managing and troubleshooting the issues of network programming in their personal as well professional life.
