     What are the difference between memory device & storage device?     The difference between memory device & storage device are given below: Memory Storage 1. It can store data temporary. 1. It can store data permanently. 2. It is volatile; that means whenever power goes off, memory device forgets everything. 2. It is non-volatile that means it can store data even when there is no power. 3. It has very small storage capacity. 3. Its storage capacity is very large. 4. Memory device is relatively expensive. 4. Storage device is relatively cheap. 5. It has direct connection with microprocessor. 5. It has no direct connection with microprocessor. 6. It is very fast. 6. It is relatively slow. 7. example: RAM 7. example: Hard disk

    We have been said to live in the computer age and now living in the information technology age. Whatever the age is, computers are the main elements shaping our lives. We use and rely on computers or related services in so many ways than we really realize. Though lagging behind the developed countries, our country has made good progress in using computers. Computers are being used in lots of fields around our lives and society. Below are the few fields that made remarkable use of computers. Education Publication Science Health and Medicine Business Industry Music Communication Entertainment Education     Computers have now become the mandatory tool for education. They are being used in classrooms, library, and laboratory everywhere everyday. The traditional chalk-blackboard classrooms have been replaced with video projectors and computers where multimedia presentations are the means of teaching. Such presentations can have colore...

     Computers are designed and built in various sizes and with different capacities. Based on the size and processing power computers are classified into few types. However, processing power, memory and storage capacity are improving so fast that definitions of different types are not valid at all the time. Following are the major types of computers. Supercomputer Mainframe Computer Minicomputer Workstation Microcomputer Desktop Computer Laptop Computer Handheld Computer Mainframe Computer      Mainframe computers are high-end computers available for general purpose use. These are designed for intensive computational task at relatively lower cost. Often they are shared by multiple users connected via terminals. A terminal is a monitor, a keyboard and sometimes a mouse connected to the mainframe computer. Mainframes are suitable for storing large volume of data. This is the reason for its use in banking and insurance industry. More re...
