What is an IP Address?

The Two Parts of an IP Address

Class A Network

Class B Network

Class C Network

Class D Network

Class E Network

1. PSTools
Got tools? Add these valuable and free server tools to your toolbox to make your computers, network and wallet very happy.
PSTools is a suite of useful command-line Windows tools that IT professionals consider essential to survival in a Windows-infested network. It provides automation tools that have no rival. There is no greater free toolset for Windows available anywhere. Microsoft provides this suite free of charge. If it's not part of your Windows diagnostic and automation arsenal, stop reading and download it now. Be sure to come back and finish the list. You can multitask, can't you?)

2. SharEnum
ShareEnum is an obscure but very useful tool. ShareEnum shows you all file shares on your network. Even better, it shows you their associated security information. This very small (94K) tool might become one of the most valuable and useful security tools that you possess. It is another free tool from Microsoft.

3. Nagios
Nagios is an enterprise infrastructure monitoring suite. It's free, mature and commercially supported. It has grown from a niche software project to a major force in contemporary network management. It's used by such high-profile companies as Citrix, ADP, Domino's Pizza, Wells Fargo, Ericsson and the U.S. Army.

4. Wireshark
If you run a network of any size or topology, Wireshark is a must-have application. It is a network packet capture and analysis program that assists you with your ongoing quest for a trouble-free network. Wireshark won't prevent network problems, but it does allow you to analyze those problems in real time and possibly avoid failure.

5. Apache
The Apache project isn't just a web server. The project, officially known as the Apache Software Foundation (ASF), consists of almost 100 different projects under the Apache umbrella. Yes, the famous and wildly popular HTTP server, Apache, is the project's namesake and mainstay, but it isn't the only nymph in the forest.

1.A byte means 8 bits and a nibblemeans 4 bits.

2.First harddisk available was of 5MB

3.Ethernet is the registered trademark 0f Xerox.

4.google uses over 10000 network computers to crawl the web.

5.Google can be queried in 26 languages

6.The floopy disk was patented byallen shugart in 1946.

7.More than 80% of web pages are in english.

8. 88% percent web pages have very low traffic rate.

9. An average american is dependent on 250 computers.

10.Internet is most fastest growing platform for advertisement.

11.About one third of CDs are pirated

12.About 76% softwares used in india are pirated.

13.Only 10% of the webpages are used by the search engines

14."I am feeling Lucky" This button is used by negligible no of people on net.

15.Bill gates & Paul Allen started a company called Traf-O-Data to
monitor traffic flow.

16.The four largest software makers in the world are:
(a) Microsoft
(b) Adobe
(c) Sap
(d) Computer Associates.
