This course covers the fundamental concepts of computer networks, standard models of computer networks having layered architecture, data communication, network topologies, web technologies and internet applications.

Learning Outcomes:

At the end of the course, students should be able to:

  • State the use of computer networks and different network topologies.
  • Distinguish between LAN, MAN, WAN, and between Intranet, Extranet and Internet.
  • Compare OSI and TCP/IP architectures.
  • Enumerate different transmission media and describe the use of each of them.
  • Design web pages using HTML.

Practicals

Lab List 1

Networking exercises in a trial lab, where effects of different connectors, topologies in practical could be demonstrated.
Before moving to JavaScript practicals, students must get an idea about fundamental programing using Scratch (https://scratch.mit.edu). Students should be encouraged to learn Scratch on their own and work on assignments available online such as https://sites.google.com/site/christopherscfahs/scratch-programming/scratch-assignments or http://scratched.gse.harvard.edu/resources/uw-catapult-project.
Alternatively, students may use Alice (http://www.alice.org/index.php) and learn basic programming. A lot of online assignments and spoken tutorials on YouTube would be helpful.
Practical exercises based on concepts listed in theory using HTML.

  1. Create HTML document with following formatting – Bold, Italics, Underline, Colors, Headings, Title, Font and Font Width, Background, Paragraph, Line Brakes, Horizontal Line, Blinking text as well as marquee text.
  2. Create HTML document with Ordered and Unordered lists, Inserting Images, Internal and External linking
  3. Create HTML document with Table:

  1. Create Form with Input Type, Select and Text Area in HTML.
  2. Create an HTML containing Roll No., student’s name and Grades in a tabular form.
  3. Create an HTML document (having two frames) which will appear as follows:

  1. Create an HTML document containing horizontal frames as follows:

  1. Create a website of 6 – 7 pages with different effects as mentioned in above problems.
  2. Create HTML documents (having multiple frames) in the following three formats:

  1. Create a form using HTML which has the following types of controls:
