CIS 105 Study Guide - Midterm Guide: Kilobyte, Printed Circuit Board, Clock Rate
Document Summary
A microcomputer"s speed is measured by its clock rate which is the cycles per second that a computer can perform its most basic tasks, measured in gigahertz. Risc (reduced instruction set computer) which are chips designed for efficiency, 64-bit processors, can only views 1"s and 0"s: 8 bits = 1 byte. 256 combnations of bits in a byte. Represent things we know, numbers, letters, commas, etc. Bus lines are controlled by software that enables the use of peripherals: pci and agp are old-school, usb and firewire win. Two-state system on a computer is called a binary system. Most computers use the american standard code for information interchange (ascii) coding scheme, using bytes to represent characters like the alphabet or numbers. Ram (random access memory) is primary storage and is volatile: a file is being worked on , but not saved. The power goes out and the file is lost. Hard drive is secondary storage, and is non-volatile.
