Case 2-2 Jack has a computer at home that he uses to access the Internet,store and edit personal photos,and create and edit documents.Recently,he has come to realize that in order to keep the computer performing at its best,he needs to carry out regular system maintenance on the computer. -Jess has pictures from her old computer saved on a flash drive.To transfer these to her new computer,she would use a(n)____ port.

Most network cards contain a port that accepts a(n)____,which looks similar to a telephone connector but is larger.

____________________ is a special group of very fast memory circuitry located on or close to the CPU.

As large documents are stored,retrieved,and then stored again,they often become ____________________-that is,not stored in contiguous (adjacent)storage areas.

Traditionally,PC Cards were used for notebook expansion.

-The accompanying figure shows a DIMM RAM microprocessor.

Several of the original ports used with desktop computers-such as the parallel ports traditionally used to connect printers-are now considered standard ports.

The control unit takes the instructions fetched by the prefetch unit and translates them into a form that can be understood by the control unit,ALU,and FPU.

Explain the difference between multiprocessing and parallel processing.

A(n)____________________ slot can be used with both the postage-stamp-sized Secure Digital (SD)flash memory cards,as well as with peripheral devices adhering to the Secure Digital Input/Output (SDIO)standard.

____________________ computing utilizes atoms or nuclei working together as quantum bits that are capable of representing more than just two states as in electronic computing of today.

Case 2-1 Jess is a musician who has just bought a new computer.Now she has to determine how to connect this computer to the devices that were connected to her old computer. -To connect her external hard drive where her music files are stored to the computer,Jess needs to use the ____ port.
