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






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






3. 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.






4. 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.






5. 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.






6. 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?






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






8. When two hard drives are configured as a single volume.






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






10. 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.






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






12. 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






13. 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.






14. 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.






15. 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






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






17. 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.






18. 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.






19. Used to repair and reinstall Windows






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






21. 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.






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






23. Uses space from two or more physical disks to increase the disk space available for a single volume. THIS writes to the physical disks evenly across all disks so that no one disk receives all the activity - and therefore improves performance. Windows






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






25. 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.






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






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






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






29. The duplication of everything written to a hard drive.






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






31. 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?






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






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






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






35. A___________________can be used to test a USB port.






36. Data storage area that provides high-speed access for the system.






37. __________________cards report computer errors and conflicts at POST.






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






39. A drive with no moving parts. Uses nonvolatile flash memory.






40. How do you change a computer's Boot Sequence?






41. 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.






42. Protocol suite to network Macintosh computers. It is comprised of a comprehensive set of protocols that span the seven layers of the OSI reference model.






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






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






45. A method of data transfer between hard drive and memory that allows multiple data transfers on a single software interrupt.






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