Starting Out with Visual C#, 5e (Tony Gaddis)Chapter 1 Introduction to Computers and ProgrammingTRUE/FALSE1.Computers can perform a wide variety of tasks because they can be programmed in ways that arespecific to the needs ofapplications.ANS:T2.Today's microprocessors are less powerful than the larger electromechanical CPUs in early computers.ANS:F3.RAM memory retains its contents when a computer is turned off.ANS:F4.Programs are usually stored in mainmemory and loaded into secondary storage as needed.ANS:F5.Most of a computer's RAM is stored in the same device that performs calculations.ANS:F6.Data is not recorded magnetically on an optical disc but is encoded as a series of pits on the discsurface.ANS:T7.The two general categories of software are system software and utility software.ANS:F8.Some examples of application software are spreadsheet programs, Web browsers, games, and emailprograms.ANS:T9.Any piece ofdata stored in a computer's memory must be stored as a decimal number.ANS:F10.The largest value that can be stored in a byte is 1.ANS:F11.The term 'pixel' stands for 'picture element.'ANS:T
