For that matter a computer couldn’t do much without. There are two types of memory RAM (random access memory) and ROM (Read-only memory). With memory a computer is able to hold applications‚ operating systems and saved files such as documents. Understanding the difference between the two types of memory is key

Delimitation The impact of technology has greatly expanded the scope and capacity of the average library. This is an on-going and developing relationship as the computer’s full capabilities are gradually explored and applied to the library. Computers have radically changed the way people learn and communicate with each other‚ as well as the library itself. The library differs little from other institutions and firms in the impact of computing technology on them. Changes are in the almost

According to Nelson Cowan article “Working memory storage capacity is important because cognitive tasks can be completed only with sufficient ability to hold information as it is processed. The ability to repeat information depends on task demands but can be distinguished from a more constant‚ underlying

research‚ I would dedicate my efforts to the design of computer processing chips with the goal of increasing their speed and computational ability. It is now possible to construct memory chips almost atom by atom‚ allowing for nearly infinite circuitry capacity. My research would attempt to design a chip that could process data faster‚ and with more accuracy‚ than is presently possible. This chip could then handle more complex software‚ process data from CD’s‚ and handle Internet applications at a faster
