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






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






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






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






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. 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.






7. The one bootable partition.






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






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






10. 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.






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






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






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






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






15. 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.






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






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






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. This can be divided into one or more logical drives. Each logical drive is assigned a drive letter (such as drive G:) and is formatted using its own file system.






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






21. Standard computer case form factor for modern computers.






22. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






23. 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?






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






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






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






28. 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






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






30. 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.






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






32. 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






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






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






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






36. 20-pin or 24-pin internal power supply connector.






37. 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.






38. Network with each computer






39. Temporary drop in AC power.






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






41. 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.






42. This is how the BIOS communicates errors during POST






43. 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.






44. 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.






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






46. 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






47. A___________________can be used to test a USB port.






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






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