1.3 Categorize each of the following items as either hardware or software: a) CPU ANS: hardware. b) C compiler ANS: software. c) ALU ANS: hardware. d) C preprocessor ANS: software. e) input unit ANS: hardware. f) a word processor program ANS: software.1.4 Why might you want to write a program in a machine-independent language instead of a machine-dependent language? Why might a machine-dependent language be more appropriate for writing certain types of programs? ANS: Machine independent languages are useful for writing programs to be executed on multiple computer platforms. Machine dependent languages are appropriate for writing programs tobe executed on a single platform. Machine dependent languages tend to exploit the efficiencies of a particular machine. 1.5 Translator programs such as assemblers and compilers convert programs from one language (referred to as the source language) to another language (referred to as the object language). Determine which of the following statements are true and which are false: a) A compilertranslates high-level language programs into object language. ANS: True. b) An assembler translates source language programs into machine language programs. ANS: True. c) A compiler converts source language programs into object language programs. ANS: False. d) High-level languages are generally machine-dependent. ANS: False. e) A machine language program requires translation before the program can berun on a computer. ANS: False.

Fill in the blanks in each of the following statements: a) Devices from which users access timesharing computer systems are usually called . ANS: terminals. b) Acomputer program that converts assembly language programs to machine language programs is called . ANS: an assembler. c) The logical unit of the computer that receives information from outside the computer for use by the computer is called . ANS: The input unit. d) The process of instructing the computer to solve specific problems is called . ANS: computer programming. e) What type of computerlanguage uses English-like abbreviations for machine language instructions? . ANS: a high-level language. f) Which logical unit of the computer sends information that has already been processed by the computer to various devices so that the information may be used outside the computer? . ANS: The output unit. g) The general name for a program that converts programs written in a certain computer...
