Exercise 8.6. Which of the listed below statements are true/false. Specify your answer using the text
1) Computer is an electronic device therefore hardware is a system of electronic devices.
2) The purpose of the input hardware is to collect data and convert it into a form suitable for computer process¬ing.
3) Scanner is used to input graphics only.
4) The purpose of processing hardware is to retrieve, interpret and direct the execution of software instruc-tions provided to the computer.
5) CPU reads and interprets software and prints the results on paper.
6) User is unable to change the contents of ROM.
7) 5.25" floppy disks are used more often because they are flexible and have more capacity than 3.5" disks.
5) Printer is a processing hardware because its pur¬pose is to show the information produced by the system.
6) Modem is an electronic device that makes possible the transmission of data from one computer to another via telephone or other communication lines.
7) The purpose of storage hardware is to store com¬puter instructions and data in a form that is relatively permanent and retrieve them when needed for process¬ing.
2) True. The purpose of input hardware, such as keyboard and mouse, is to collect data and convert it into a format that can be processed by the computer.
3) False. A scanner is used to input both graphics and text. It converts physical documents or images into a digital format that can be stored or edited on a computer.
4) True. The processing hardware, primarily the central processing unit (CPU), retrieves software instructions, interprets them, and directs the execution of these instructions to perform tasks.
5) False. The CPU reads and interprets software instructions, but it does not directly print the results on paper. The printer hardware is responsible for producing hard copies of the information processed by the system.
6) True. ROM (Read-Only Memory) is a type of storage in a computer that contains permanent instructions or data. Its contents cannot be changed by the user.
7) False. 3.5" floppy disks are used more often than 5.25" disks as they are more compact and have higher storage capacity. 5.25" disks are considered older technology.
8) False. A printer is an output hardware device, not a processing hardware. Its purpose is to produce a physical representation (printout) of the information processed by the computer system.
9) True. A modem is an electronic device that enables data transmission between computers via telephone lines or other communication channels.
10) True. Storage hardware, like hard drives or solid-state drives, is used to store computer instructions and data in a relatively permanent form that can be accessed later for processing.
