What is a card reader?

A device with which you can read data from one of several types of flash memory.

You have been tasked to provide removable media for each of the technicians in your department. One tech wants a card reader and SD cards, and another wants a USB thumb drive. Write a memo outlining the advantages of each technology and make a recommendation.

A good answer here shows that SD cards and thumb drives are based on the same flash memory technology but have very different form factors. The SD cards are smaller but not as robust for shoving in pockets. Having card readers installed can provide more flexibility with other card types.

Your department is getting ready to replace the old computers, and your boss Mrs. Turner has asked you to investigate what kind of optical drives the new computers should have. Write a memo to your boss listing the device(s) you have selected and justifying your choice(s).

Answers will vary, but the student should have eliminated regular CD-ROM drives and the CD-R drives. The CD-RW is acceptable and, if cost is a factor, may be the best solution. The student may choose to combine a CD-RW with a DVD, justifying the rapid growth of DVD media and its higher storage capacity. That way, the CD-RW provides write capabilities while the DVD provides high-capacity read capability. Depending on how the computers would be used and the budget for the computers, the student may select DVD-R or DVD-RAM to get write capabilities with the higher capacity of DVD. The DVD-R is recordable but not rewritable, and the DVD-RAM is recordable and erasable. Newer DVD-R/RW or DVD+R/RW can also erase and rewrite. The advantage of the DVD+R/RW is that it can also read CD-ROM.

Your friend Jack's hard drive died last week, so he bought a new hard drive and installed it. Now he's trying to install Windows 2000, but his computer will not boot to the CD-ROM drive. He's called you for help. What does he need to do to get his computer to recognize and boot to the CD-ROM drive so he can install the OS?

Because the Windows 2000 disc is bootable, Jack's problem is the CMOS boot sequence. He should access the CMOS setup screen and change the boot sequence so that the computer looks first at the CD-ROM drive. After he completes the installation of his OS, he can reset the boot sequence.
