Research can be classified in many different ways on the basis of the methodology of research, the knowledge it creates, the user group, the research problem it investigates etc,. BASIC RESEARCH The research which is done for knowledge enhancement, the research which does not have immediate commercial potential. The research which is done for human welfare, animal welfare and plant kingdom welfare. It is called basic, pure, fundamental research. The main motivation is to expand man's knowledge, not to create or invent something. APPLIED RESEARCH Applied research is designed to solve practical problem of the modern world, rather than to acquire knowledge for knowledges sake. The goal of applied research is to improve the human condition. It focus on analysis and solving social and real life problems. This research is generally conducted on large scale basis, it is expensive. As such, it often conducted with the support of some financing agency like government, public corpo...

SRAM : Static random access memory uses multiple transistors, typically four to six, for each memory cell but doesn't have a capacitor in each cell. It is used primarily for  cache . The following are some common types of RAM: ·          DRAM :  Dynamic random access memory  has memory cells with a paired transistor and  capacitor  requiring constant refreshing. ·          FPM DRAM :  Fast page mode dynamic random access memory  was the original form of DRAM. It waits through the entire process of locating a bit of data by column and row and then reading the bit before it starts on the next bit. Maximum transfer rate to L2 cache is approximately 176 MBps. ·          EDO DRAM :  Extended data-out dynamic random access memory  does not wait for all of the processing of the first bit before continuing to the next one. ...
