Subject : it-skills
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. 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






2. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






3. A unit of measure that describes the size of a data file - the amount of space on a disk or other storage medium - or the amount of data being sent over a network. One byte consists of 8 bits of data.






4. The resistor added at the end of a SCSI chain to dampen the voltage at the end of the chain.






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






6. __________________cards report computer errors and conflicts at POST.






7. Generally the label for the first hard drive in a computer system. Drive A and Drive B are reserved for floppy drives. Drive B is rarely used on current computers.






8. A single hard drive that works independently of other hard drives.






9. 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.






10. Discovers the local address (MAC address) of a station on the network when the IP address is known. End stations as well as routers use ARP to discover local addresses:






11. Also known as redundant array of independent disks: Technology uses an array of hard drives used to provide fault tolerance and/or improvement in performance.






12. A___________________can be used to test a USB port.






13. The term__________refers to the computer bringing itself up to a working state without the user having to do anything but press the on button.






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






15. The latest SCSI standard - serial SCSI - also called serial attached SCSI - allows for more than 15 devices on a single SCSI chain - uses smaller - longer - round cables - and uses smaller hard drive form factors that can support larger capacities th






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






17. Troubleshooting tool that allows the computer to boot from a disk when the hard drive will not boot.






18. 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.






19. 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.






20. A drive with one - two - or more platters - or disks that stack together and spin in unison inside a sealed metal housing that contains firmware to control reading and writing data to the drive and to communicate with the motherboard. The top and bot






21. A set of tools - routines and protocols used to develop software applications that will be compatible with an operating system.






22. Formatting performed by means of the DOS or Windows Format program (for example - FORMAT C:/S creates the boot record - FAT - and root directory on drive C and makes the drive bootable). Also called OS formatting.






23. Performed from the operating system - such as by pressing the key combination Ctrl+Alt+Del or by choosing a Restart option from the Shut Down dialog box. Less stressful on the computer.






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






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






26. Method for encrypting data on a network. Uses a private key for writing messages and a public key to decode the messages. Only the private key needs to be kept secret. Public keys can be distributed openly.






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






28. Memory that does not lose its data when the power is turned off.






29. 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.






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






31. The one bootable partition.






32. 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






33. 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.






34. 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?






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






36. A transfer mode that uses the CPU to transfer data from the hard drive to memory. This mode is slower than DMA mode.






37. Temporary drop in AC power.






38. 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.






39. 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.






40. The 12-bit wide - one-column file allocation table for a floppy disk - containing information about how each cluster or file allocation unit on the disk is currently used.






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






42. Physical connection between an interface processor or card - the data buses - and the power distribution buses inside a chassis.






43. POST means __________________.






44. 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






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






46. A transfer mode used by devices - including the hard drive - to transfer data to memory without involving the CPU.






47. 20-pin or 24-pin internal power supply connector.






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