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. 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






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






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






4. 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.






5. 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






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






7. 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.






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






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






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. 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






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






13. 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.






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






15. 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.






16. 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






17. 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.






18. __________________cards report computer errors and conflicts at POST.






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. 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.






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






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






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






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






25. Temporary drop in AC power.






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






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






28. 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.






29. 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.






30. Standard computer case form factor for modern computers.






31. The ________________makes sure the computer meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process.






32. 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.






33. 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?






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






35. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






38. 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.






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






40. 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






41. 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.






42. 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.






43. 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.






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






45. 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.
