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.

A mainframe computer is large, expensive, and capable of simultaneously processing data for hundreds or thousands of users. Small, portable digital devices that allow you to install apps can be classified ashandheld computers.A microcontroller is a special-purpose microprocessor that can control a device, such as a refrigerator or microwave oven. 1.computer 2.memory, RAM, random access memory 3.unit 4.program 5.software 6.file 7.stored 8.Application 9.System 10.operating 11.personal 12.workstation 13.supercomputer 14.mainframe 15.handheld, hand-held, hand held 16. Summary C Digital data is processed, stored, and transmitted as a series of 1s and 0s. Each 1 or 0 is called a bit. A series of eight 0s and 1s, called a byte, represent one character—a letter, number, or punctuation mark. Data becomes information when it is presented in a format that people can understand and use. Numeric data consists of numbers that might be used in arithmetic operations. It can be represented digitally using the binary number system. Character data is composed of letters, symbols, and numerals that are not used in arithmetic operations. Computers represent this type of data using ASCII, EBCDIC, or Unicode. Data is quantified using terms such as kilobyte or kibibyte (1024 bytes), and prefixes, such as mega or mebi (1,048,576), and giga or gibi (1,073,741,824). The bits that represent data travel as electronic pulses through integrated circuits, sometimes called computer chips. These chips are made from semiconducting materials and are housed in chip carriers that can be plugged into the system board of a digital device. 1.Digital, Binary 2.bit 3.byte 4.information 5.Numeric 6.binary 7.Character, Text 8.ASCII 9.kilobyte 10.mega 11.gibi 12.integrated 13.semiconducting 14.system, mother,
