Exam 10: Understanding Computer Hardware and Software: From CPUs to Operating Systems

Complex instruction set computer chips limit the number of instructions the CPU can execute to increase processing speed.

What is a computer designed to meet the computing needs of several people simultaneously in a small to medium-size business environment?

What provides additional functionality to the operating system?

Personal information management (PIM)software handles contact information,appointments,task lists,and email.

System software controls how the various technology tools work together along with the application software.System software includes both operating system software and utility software.

A desktop computer is an electronic book that can be read on a computer or special reading device.Some are small enough to carry around,while others are the size of a telephone booth.

What software organizes information on a hard disk in the most efficient way?

Preventative security software uses programs such as Window Washer,erases file histories,browser cookies,cache contents,and other crumbs that applications and Windows leave on a hard drive.

What is a computer that sits on,next to,or under a user's desk and is too large to carry around?

What is the computer's primary working memory,in which program instructions and data are stored so that they can be accessed directly by the CPU via the processor's high-speed external data bus?

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

What is a type of CPU that can recognize as many as 100 or more instructions,enough to carry out most computations directly?

What detects the presence or absence of a mark in a predetermined place (popular for multiple-choice exams)?

Disk image is software for data recovery and relieves the burden of reinstalling applications if a hard drive crashes or becomes irretrievably corrupted.

Email provides email services for computer users,including receiving mail,sending mail,and storing messages.Leading email software includes Microsoft Outlook,Microsoft Outlook Express,and Eudora.

A supercomputer is the fastest,most powerful,and most expensive type of computer.Organizations such as NASA that are heavily involved in research and number crunching employ supercomputers because of the speed with which they can process information.Other large,customer-oriented businesses such as General Motors and AT&T employ supercomputers just to handle customer information and transaction processing.

Which license restricts the use of the software to one user at a time?

What occurs when the software vendor releases a new version of the software making significant changes to the program?

Gigahertz is the number of millions of CPU cycles per second.

An input device is equipment used to capture information and commands.
