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. 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






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






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






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






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






6. 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.






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






8. 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.






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. 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






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






12. POST means __________________.






13. The one bootable partition.






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






15. 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.






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






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






18. 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.






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






20. 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.






21. 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






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






23. 20-pin or 24-pin internal power supply connector.






24. 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






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






26. 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






27. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






28. 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.






29. Performed from the operating system - such as by pressing the key combination Ctrl+Alt+Del or by choosing a Restart option from the Shut Down dialog box. Less stressful on the computer.






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






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






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






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






34. 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.






35. Network with each computer






36. 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.






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






38. 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?






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






40. Involves restarting the computer by pressing the on/off switch. Stressful on computers.






41. 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.






42. 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.






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






44. 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






45. 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.






46. Windows Vista technology that supports a hybrid drive.






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






48. A___________________can be used to test a USB port.






49. 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.






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