Back | Week 2 | Week 3  | Week 5  | Week 6 | Week 7 | Week 8 | Week 9 | All 

Aims

The concepts of decimal, hexadecimal and binary conversions are important in networking, as many network addresses uses these techniques. The activities in this weeks practical are intended to revise the concept of hexadecimal, decimal and binary conversions. It also involves a practical worksheet which uses the ping command, and the determination of the main networking parameters from a workstation.

Please remember that the module requires around 10 hours study each week (three hours supervised, and seven hours unsupervised). Thus along with this supervised work you should also complete the following this week:

arrowIndependent research

arrowProblem solving

When you have the answers to these, please submit them from each of the pages.

Activity 1: Hex, binary and decimal

Time to complete: Approx 5 minutes

Background

In this activity you should complete the table below until you get 12 correct answers.

 

Activity 2: Converting from binary strings to hex and decimal

Time to complete: Approx 5 minutes

Background

In this activity a binary string is split into bytes, and then converted into decimal and hexadecimal.

 

Activity 3: Bit rate to bit timing

Time to complete: Approx 5 minutes

Background

In this activity you must convert the bit rate into an exponent format, and then calculate the time for a single bit.

 

Activity 4: IPCONFIG

Time to complete: Approx 5 minutes

IPCONFIG is one of the most widely used commands in networking. The following provides an emulator of some of its functions. Type ? for help. If your commands do not appear at the bottom, click on the emulator, and then they should appear.

1. The IP addresses of the new adapters, and their associated gateway address and subnet mask.
2. The local domain name.
3. The DNS server addresses.
4. The MAC addresses of the network cards.
5. Release the 192.168.0.2 adapter.
6. Renew it.

Activity 4: Worksheet 2

Time to complete: Approx 30 minutes
