Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Set of conductors - bundled and sheathed together - made of insulated copper or optical fiber that transport signals and power between electrical devices.






2. Speed at which bits are transmitted - usually expressed in bits per second (bps).






3. The first sector of a floppy disk or logical drive in a partition; it contains information about the disk or logical drive. On a hard drive - if the THING is in the active partition - then it is used to boot the OS. Also called boot sector.






4. Standard that specifies full SATA cabling for external disks.






5. Storage area used for handling data in transit. Buffers are used in internetworking to compensate for differences in processing speed between network devices. Bursts of data can be stored in buffers until they can be handled by slower processing devi






6. Order of drives checked for an OS. Example: Floppy (1st) - CD-ROM (2nd) Hard Drive (3rd)






7. In Windows XP - you should choose the _______________setting for updates.






8. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






9. A number from 0 to 15 assigned to each SCSI device attached to the daisy chain.






10. A feature of system BIOS and hard drives that automatically identifies and configures a new drive in CMOS setup.






11. Commonly called the host adapter. The host adapter is inserted into an expansion slot on the motherboard and is responsible for managing all devices on the SCSI bus. A host adapter can support both internal and external SCSI devices - using one conne






12. A Data Link layer device that connects and passes frames between two network segments. The frames are filtered and forwarded using MAC addresses.






13. A self-monitoring technology whereby the BIOS monitors the health of the hard drive and warns of an impending failure.






14. An ATAPI cabling method that uses a narrower and more reliable cable than the 80-conductor cable.






15. Most often called a hard drive - comes in two sizes for personal computers: the 2.5" size is used for laptop computers and the 3.5" size is used for desktops. In addition - a smaller 1.8" size (about the size of a credit card) hard drive is used in s






16. A computer's ability to respond to a fault or catastrophe - such as a hardware failure or power outage - so that data is not lost.






17. A drive that uses both solid state and magnetic technologies.






18. Temporary drop in AC power.






19. A number assigned to a logical device (such as a tray in a CD changer) that is part of a physical SCSI device - which is assigned a SCSI ID.






20. Involves restarting the computer by pressing the on/off switch. Stressful on computers.






21. Hardware or software systems that can use interfaces and data from earlier versions of the system or with other systems. Also known as backward-compatible or backwards compatible.






22. Cable that contains four pairs of wires - with a maximum data rate of 1 Gbps.






23. A sealed - magnetic coil device that moves across the surface of a disk either reading data from or writing data to the disk.






24. The top or bottom surface of one platter on a hard drive. Each platter has two of these.






25. Issues dial - hang up - reset - and other instructions to the modem. It is based on the Hayes command set.






26. Layer 7 of the OSI reference model. This layer provides services to application processes such as electronic mail - file transfer - and terminal emulation that are outside of the OSI model. The application layer identifies and establishes the availab






27. Standard computer case form factor for modern computers.






28. When troubleshooting a failed boot - if you do not see any lights or hear any noises - what hardware system do you first assume is at fault?






29. The advantages of ______________: To reduce the likelihood that the events that causes PC failures will occur and to lessen the damage if they do.






30. A preventive maintenance plan tends to evolve from a history or pattern of __________malfunctions within an organization.






31. A________________CD can be used to boot a system and repair or reinstall Windows.






32. The overall structure an OS uses to name - store - and organize files on a drive. In it - a cluster is the smallest unit of space on a disk for storing a file and is made up of one or more sectors. A it tracks how these clusters are used for each fil






33. An interface standard - part of the IDE/ATA standards - that allows tape drives - CD-ROM drives - and other drives to be treated like an IDE hard drive by the system.






34. One or more sectors that constitute the smallest unit of space on a disk for storing data (also referred to as a file allocation unit). Files are written to a disk as groups of whole clusters.






35. A fast interface between a host adapter and the CPU that can daisy chain as many as 7 or 15 devices on a single bus.






36. Applet or small program created by Microsoft to control interactivity on web pages that has to be downloaded to gain access to the full functionality.






37. Four Main Parts of the boot process: 1. BIOS checks hardware through POST. 2. The ___________ searches for and loads an OS. 3. The OS configures the system and completes its own loading. 4. The user executes application software.






38. The circuit board that controls a SCSI bus supporting as many as seven or fifteen separate devices. This device controls communication between the SCSI bus and the PC.






39. Media through which data is transferred from one part of a computer to another. The bus can be compared to a highway on which data travels within a computer.






40. An IDE cable that has 40 pins but uses 80 wires - 40 of which are ground wires designed to reduce crosstalk on the cable.






41. __________________cards report computer errors and conflicts at POST.






42. An older IDE cabling method that uses a 40-pin flat data cable or an 80-conductor cable and a 40-pin IDE connector.






43. This can be divided into one or more logical drives. Each logical drive is assigned a drive letter (such as drive G:) and is formatted using its own file system.






44. List managed by a network administrator that itemizes what a user is permitted to access and the type of access granted.






45. Network with each computer






46. A process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface.






47. Command used to check the integrity of files and folders on a hard drive by scanning the disk surface for physical errors.






48. Is a type of drive imaging. It duplicates data on one drive to another drive and is used for fault tolerance.






49. Five possible questions that should be asked of a user who is experiencing computer problems: What had just happened? What recent changes did the user make? When did the computer __________? What error message do you see?






50. Stripes data across three or more drives and uses parity checking - so that if one drive fails - the other drives can re-create the data stored on the failed drive. Data is not duplicated - and - therefore - THIS makes better use of volume capacity.
