p. 242. The small computer
- Darrel Ince
‘The small computer’ shows how the huge advancements in computing over the past thirty years have been made possible. Computer processors evolved from using mechanical circuits to transistors, and eventually to the silicon chips containing huge numbers of transistors that we see today. A computer processor links these circuits through logic gates to perform actions on binary data. Computer memory can either be read–only memory (ROM) or read–write memory (RWM)–the RAM in your PC falls into the latter category. Larger files are stored on hard disks, which are much slower and noisier than RAM. Current technologies are approaching plateaus in performance, which researchers are trying to overcome.
