ANA300Y1 Study Guide - Final Guide: Binary Number, Readwrite, Printed Circuit Board
Document Summary
System hardware: brains and heart of computer. Storage: means to store data and software applications permanently, hard disk drive, usb flash drive, cd and dvd drives. Switches: along with the many transistors, other components critical to a circuit board (such as resistors, capacitors, and diodes) are also located on the integrated circuit, most integrated circuits are no more than a quarter inch in size. Integrated circuits have enabled computer designers to create small yet powerful microprocessors, which are chips that contain a cpu. The binary number system: computers describe a number of powers of 2 because of the two switch positions (on and off). This numbering system is referred to as the binary number system the number system used by computers to represent all data. Cache memory: consists of small blocks of memory located directly on and next to the cpu chip, memory blocks hold places for recently and frequently used instructions or data that the cpu needs most.
