Question 24: One advantage of information processing is that ________. a) a face-to-face interaction among staff may be reduced Information processing often automates tasks and facilitates communication through digital means, which can reduce the need for face-to-face interaction. Question 25: When information is conveyed from one place to another it is referred to as information ________. c) transmission Information transmission is the process of sending information from a source to a receiver. Question 26: Is a mode of receiving information through print alone with not sound or voice. b) Visual Receiving information through print alone, without sound or voice, relies solely on the visual sense. Question 27: Which of the following is an example of a software. a) operating system An operating system is a type of system software that manages computer hardware and software resources. Keyboard, joystick, and mouse are hardware components. Question 28: Computer software is classified into parts. c) 2 Computer software is primarily classified into two main types: System Software and Application Software. Question 29: Word processing, spreadsheet, database, graphics and presentation software are all examples of ________. a) Application software Application software consists of programs designed to perform specific tasks for the user. Question 30: The two main of transmitting information are ________. d) Computer and electronic In modern contexts, information transmission largely relies on computer networks and electronic signals. Question 31: Which of the following source if information is received by the user in visual mode only. c) photograph A photograph provides information purely through visual means, without sound or other sensory input. Question 32: A major function of system soft-ware. c) file organization File organization is a core function of an operating system, which is a type of system software, managing how files are stored and accessed. Question 33: The operation of a computer and peripheral is attached to it controller by. d) system software System software, particularly the operating system and device drivers, controls the operation of a computer and its peripherals. Question 34: Is an example of an operating system. c) MS-software Assuming "MS-software" refers to an operating system like MS-DOS or MS-Windows (as "MS-" is often used as a prefix for Microsoft operating systems), this would be the correct option.
