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






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






3. The circuit board that controls a SCSI bus supporting as many as seven or fifteen separate devices. This device controls communication between the SCSI bus and the PC.






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






5. 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






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






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






8. 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.






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






10. 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






11. 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.






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






13. 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.






14. 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.






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






16. The one bootable partition.






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






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






19. 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.






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






21. 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.






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






23. 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






24. 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.






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






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






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






28. 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.






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






31. 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






32. 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.






33. This is how the BIOS communicates errors during POST






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






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






36. 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






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






38. 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.






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






40. 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






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






42. A___________________can be used to test a USB port.






43. 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.






44. Temporary drop in AC power.






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






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






47. 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.






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






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






50. 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.
