Exam 22: B: Extension: A Hardware and Software Basics

Operating system software controls the application software and manages how the hardware devices work together.When using Excel to create and print a graph, the operating system software controls the process, ensures that a printer is attached and has paper, and sends the graph to the printer along with instructions on how to print it.Some computers are configured with two operating systems so they can dual boot-provide the user with the option of choosing the operating system when the computer is turned on.

Cache memory is a small unit of ultra-fast memory that is used to store recently accessed or frequently accessed data so that the CPU does not have to retrieve this data from slower memory circuits such as RAM.

What is the measurement term for the number of millions of CPU cycles per second?

What software handles contact information, appointments, task lists, and email?

System restore enables a user to return to the previous operating system.

A minicomputer is designed to meet the computing needs of several people simultaneously in a small to medium-size business environment.

What computer has a flat screen that uses a mouse or fingertip for input instead of a keyboard?

Multitasking allows more than one piece of software to be used at a time.Multitasking is used when creating a graph in Excel and simultaneously printing a word processing document.

Define the relationship between operating system software and utility software.

What is a form of a stationary mouse on which the movement of a finger causes the pointer on the screen to move?

Personal information management software contains course information such as a syllabus and assignments and offers drop boxes for quizzes and homework along with a grade book.

A desktop computer is portable enough to fit on a lap or in a bag and has its own power source or battery.

What is hardware?

What uses programs such as Window Washer which erases file histories, browser cookies, cache contents, and other crumbs that applications and Windows leave on a hard drive?

What is the actual hardware that interprets and executes the program (software) instructions and coordinates how all the other hardware devices work together?

What is a CPU?

A megabyte (MB or M or Meg) is roughly 1 million bytes.

What is a small unit of ultra-fast memory that is used to store recently accessed or frequently accessed data so that the CPU does not have to retrieve this data from slower memory circuits such as RAM?

Which license enables anyone on the network to install and use the software?

ROM is nonvolatile, meaning it does not require constant power to function.ROM contains essential system programs that neither the user nor the computer can erase.Since the computer's internal memory is blank during start-up, the computer cannot perform any functions unless given start-up instructions.
