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. A table on a hard drive or floppy disk that tracks how space on a disk is used to store files.






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






3. This is how the BIOS communicates errors during POST






4. 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






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






6. 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.






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






8. 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.






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






10. 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?






11. Expansion card that increases the number of controllers and ports available on a computer.






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






13. You should write down or backup changes to CMOS/BIOS setup ____________________.






14. 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.






15. Having the ability to connect and disconnect a drive while the system is running. Also called hot-plugging.






16. 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






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






19. A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.






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






21. 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.






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






23. The process - you specify the size of the partition and what file system it will use.






24. 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.






25. 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:






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






27. High-speed - 32-bit bus technology designed to support the acceleration of 3D computer graphics.






28. 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.






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






30. A___________________can be used to test a USB port.






31. 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.






32. A hard drive whose disk controller is integrated into the drive - eliminating the need for a controller cable and thus increasing speed - as well as reducing price.






33. Temporary drop in AC power.






34. 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.






35. 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.






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






37. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A






38. 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?






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






40. The volume is assigned a drive letter (such as drive C: or drive D:) and is formatted using a file system. Also called simple volume.






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






42. 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.






43. Backs up user-selected files to tape. This backup does not reset the archive bit.






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