Use of Internet in Education

                  The Internet, a global network of networks connecting millions of computers and computer users, is a relatively new resource for educators. In fall 1998, 89-percent of U.S. public and private schools and 51 percent of all classrooms had Internet access (Wirt, 1999). The Internet’s rapid growth and dynamic nature has educators asking research questions that are still in the process of being studied. Researchers are only beginning to gain insight into the strengths and weaknesses of the Internet in the classroom. However, even at this early stage, there is emerging evidence that the Internet provides a variety of valuable aids to education.





             The Internet provides up-to-date information on a variety of classroom-related topics unavailable from other sources. The content of textbook, library, and teacher knowledge is enhanced by this new medium.
Computer networks are increasingly serving as an aid to communication and to the storage and retrieval of information. In that sense, the Internet can be thought of as a natural extension of 5,000 years of progress that began with the development of reading and writing, and has included inventions such as the movable type printing press, telegraph, telephone, radio, television, VCR, and communications satellites (Logan, 1995). Some of the educational research on print materials, telephone, radio, television, and video carry over to the...

Memory Management Techniques

Computer must require some memory to store the data, doing some process and for generate some output. Many years ago when RAM (Random Access Memory) is considered as a main memory at that time some problems were came.

RAM has two drawbacks 1. Speed
                                        2. Capacity

Speed in comparison with the processor and capacity in comparison with Hard Disk Drive (HDD). To reduce this drawback some memory management techniques were invented. Some of them written below.

  • Instruction Pre-fetch
  • Write Buffer
  • Memory Interleaving
  • Cache Memory
  • Virtual Memory
So these are the techniques to reduce the drawback of the RAM. This techniques known as memory management techniques.

Dr. Manmohan Sigh - " A True Leader "



"Knowing is not enough; we must apply.
                     Willing is not enough; we must do. "

                                


Dr. Manmohan Singh is the14th and current Prime Minister of India. He is the first Sikh Prime Minister of our peaceful and loving nation. As we always taking and learning about the technology, and we also concern with leadership in many ways. We should know few things about our 14th prime minister. To become the prime minister of world's one the most populated nation, and world emerging nation is something special. We always understand that a leader should have good speaker and he should have the ability to present knowledgeable speech in large gathering. And convert their mind into his opinion.              Dr. Manmohan Singh is always being different from any political leader. And I feel very glad to introduce him as our nation leader rather than political leader.

                       Sometimes, I feel that Dr. Manmohan Singh is our nation proud. He is role model of many students and young people in our country and outside also. Let see some important facts of Dr. Manmohan Singh.

Cache Memory

                           If you have been shopping for a computer, then you have heard the word "cache." Modern computer­s have both L1 and L2 caches, and many now also have L3 cache. You may also have gotten advice on the topic from well-meaning friends, perhaps something like "Don't buy that Celeron chip, it doesn't have any cache in it!" ­ It turns out that caching is an important computer-science process that appears on every computer in a variety of forms. There are memory caches, hardware and software disk caches, page caches and more. 



                     A small amount (normally less than 1MB or 2MB) of high-speed memory residing on or close to the CPU. Cache memory supplies the processor with the most frequently requested data and instructions. Level 1 cache (primary cache) is the cache closest to the processor. Level 2 cache (secondary cache) is the cache second closest to the processor and is usually on the motherboard.

                   A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations.

                  Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory.



                Cache memory is sometimes described in levels of closeness and accessibility to the microprocessor. An L1 cache is on the same chip as the microprocessor. (For example, the PowerPC 601 processor has a 32 kilobyte level-1 cache built into its chip.) L2 is usually a separate static RAM (SRAM) chip. The main RAM is usually a dynamic RAM (DRAM) chip.
