What are the first 100 websites in the internet
Thursday, December 16, 2010
The Internet domain game has been going strong for over 20 years. Have you ever thought back and wondered what some of the first domain registrations were? Surprisingly the first domain name ever registered was symbolics.com. Below you will find the list of the first 100 domain names registered.
If only you were able to predict at that time how vast the internet would expand you could have made loads of money. Simple three letter domain names now sell for hundreds of thousands of dollars. It's no surprise that the first 100 list is compromised of many large corporations as it surely cost more than $1.99 to register a domain name in the 1980's. Interestingly Microsoft.com isn't part of the list as it was not registered until May 1991.
1. symbolics.com: March 15, 1985
2. bbn.com: April 24, 1985
3. think.com: May 24, 1985
4. mcc.com: July 11, 1985
5. dec.com: Sept. 30, 1985
6. northrop.com: Nov. 7, 1985

What is paging ? what is the use of paging
In computer operating systems, paging is one of the memory-management schemes by which a computer can store and retrieve data from secondary storage for use in main memory. In the paging memory-management scheme, the operating system retrieves data from secondary storage in same-size blocks called pages. The main advantage of paging is that it allows the physical address space of a process to be noncontiguous. Before the time paging was used, systems had to fit whole programs into storage contiguously, which caused various storage and fragmentation problems
Difference between volatile and const?( constant)

C Material , ANSI C BY Dennis Ritche Ebook Download
The C Programming Language is a well-known programming book written by Brian Kernighan and Dennis Ritchie, the latter of whom originally designed and implemented the language (as well as co-designed the Unix operating system with which development of the language was closely intertwined). The book was central to the development and popularization of the C programming language and is still widely read and used today. Because the book was co-authored by the original language designer, and because the first edition of the book served for many years as the de facto standard for the language, the book is regarded by many to be the authoritative reference on C
