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

List the common input,output,storage,and communication devices.

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

What is the size of the internal electrical pathway along which signals are sent from one part of the computer to another?

Application software is used in computer appliances and special-purpose applications,such as an automobile,ATM,or media player and are used for a single purpose.

Utility software provides additional functionality to the operating system.

A workstation computer is similar to a desktop but has more powerful mathematical and graphics processing capabilities and can perform more complicated tasks in less time.

Complex instruction set computer (CISC)chips,which is a type of CPU that can recognize as many as 100 or more instructions,enough to carry out most computations directly.

What is roughly 1 million bytes?

A handheld computer portable enough to fit in a purse or pocket and has its own power source or battery.

A single user license restricts the use of the software to one user at a time.

What software can remove software that is no longer needed?

Explain the difference between primary and secondary storage.

Which of the following represents megahertz?

Identify the different computer categories and explain their potential business uses.

Megahertz is the number of billions of CPU cycles per second.

What interprets software instructions and literally tells the other hardware devices what to do,based on the software instructions?

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.

What performs all arithmetic operations (for example,addition and subtraction)and all logic operations?

What is a small handheld computer that performs simple tasks such as taking notes,scheduling appointments,and maintaining an address book and a calendar?

Volatility refers to a device's ability to function with or without power.RAM is volatile,meaning it must have constant power to function; its contents are lost when the computer's electric supply fails.
