Acomputer is a multipurpose device that accepts input, processes data, stores data, and produces output, all according to a series of stored . the processing unit of most modern computers is a(n) . the instructions that tell a computer how to carry out a task are referred to as computer , which are distributed as software. computers run three main types of software: software, system software, and development tools. an example of system software is a computer system, which is essentially the master controller for all the activities that a digital device performs. digital devices are constructed using tiny electronic components that represent data bits as electrical signals. the system unit houses the system board, which contains several circuits made from semiconducting materials. computers come in three popular form factors: component, , and slate. many of today's digital devices operate on battery power supplied by ion batteries. battery life and lifespan can be extended by following good battery management practices.

Data is processed, stored, and transmitted as a series of 1s and 0s. each 1 or 0 is called a(n) . a series of eight 0s and 1s, called a(n) , represents one character—a letter, number, or punctuation mark. data becomes when it is presented in a format that people can understand and use. digital signals are represented by two different , such as +5 volts and +.2 volts. digital data can also take the form of light and dark spots etched onto the surface of a cd or the positive and negative orientation of particles on the surface of a hard disk. data consists of numbers that might be used in arithmetic operations. it can be represented digitally using the number system. data is composed of letters, symbols, and numerals that are not used in arithmetic operations. computers represent this type of data using , ebcdic, unicode, or utf-8. data is quantified using terms such as or kibibyte (1024 bytes), and prefixes such as or mebi (1,048,576), and giga or (1,073,741,824). to reduce file size and transmission times, digital data can be compressed. compression provides the means to compress data and reconstitute it into its original state. compression throws away some of the original data during the compression process. compressed files usually have at the end of the file name and are represented with special icons. these files have to be or unzipped before you can view the data they contain.
