Troubleshooting Network Connectivity Issues - The PING Command


PING stands for Packet INternet Grouper.
It’s a tool available in computers and network devices to help in troubleshooting connectivity issues.
Two computers are said to be successfully connected at the network level if they can successfully PING each other.

The ping command is usually supplied with the destination IP or hostname of the PC you wish to ping.


C:\Program Files\ICW>ping

Pinging [] with 32 bytes of data:
Reply from bytes=32 time=459ms TTL=52
Reply from bytes=32 time=475ms TTL=52
Reply from bytes=32 time=451ms TTL=52
Reply from bytes=32 time=467ms TTL=52

Ping statistics for
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 451ms, Maximum = 475ms, Average = 463ms

A ping is successful if it returns replies from the remote/destination PC/host.

CCNA - Understanding a class B network address

Class B Network Address

The designers of the Internet decided to create classes of networks based on network size.
A “class B” network address has its first 2 octets (2bytes or 16 bits) assigned to identify the network and the last 2 octets (16 bits) assigned to identify a host on that network.

If     N = Network bit
   H = Host bit


A bit can take on a two values (0 or 1), meaning;

Class A can have up to 2^8 = 256 networks and 2^24 = 16,777,216 hosts.
Class B can have up to 2^16 = 65,536 networks and 2^16 = 65,536 hosts.
Class C can have up to 2^24 = 16,777,216 networks and 2^8 = 256 hosts.

For the small number of networks possessing a very large number of nodes, they created the rank “Class A” network. At the other extreme is the “Class C” network, which is reserved for the numerous networks with a small number of nodes. The class distinction for networks between very large and very small is predictably called the “Class B” network.

In a “Class B” network, the first bit of the first byte must always be turned ON (set to 1) but the second bit must always be turned OFF (set to 0). If you turn the other 6 bits all OFF and then all ON, you will find the range for a Class B network:

10000000 = 128
10111111 = 191

As you can see, a Class B network is defined when the first byte is configured from 128 to 191.

How to connect your PC/Laptop to your TV/LCD

Today new TVs/LCDs come with the PC VGA input port and it’s very easy to connect your laptop to your giant screen and enjoy the movies you saved on your hard disk. All you need for this simple setup is a VGA cable; connect one end to the PC VGA port and the other end to your TV and select PC input from your TV input menu.

However, some people still own the old model TVs which don’t have the VGA port! The good news it is still possible to connect your PC or Laptop to your Television set and also enjoy movies, pictures, videos from your PC/Laptop.
For this kind of setup, you need a “PC VGA to TV S-Video”.

The converter comes with the VGA cable and S-Video cable.

See how you will hook it up in the diagram below:

Have fun!
