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






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






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






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






5. 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.






6. 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.






7. 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:






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






9. 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






10. 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.






11. POST means __________________.






12. A nonprofit organization dedicated to creating trade and communications standards.






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






14. 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?






15. Set of conductors - bundled and sheathed together - made of insulated copper or optical fiber that transport signals and power between electrical devices.






16. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






17. A___________________can be used to test a USB port.






18. To power up a computer from the off position.






19. __________________cards report computer errors and conflicts at POST.






20. 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.






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






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






23. 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.






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






25. 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.






26. 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.






27. Temporary drop in AC power.






28. 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






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






30. 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






31. 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.






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






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






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






35. 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.






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






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






38. Fastener used to bundle cables inside and outside of a computer.






39. 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






40. 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.






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






42. 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






43. 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






44. 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.






45. 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.






46. Windows Vista technology that supports a hybrid drive.






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






48. 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.






49. 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.






50. This tool can be used to test a USB port.
