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. Standard that specifies full SATA cabling for external disks.






2. 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






3. The one bootable partition.






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






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






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






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






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






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






10. 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.






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






12. POST means __________________.






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






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






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






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






17. 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






18. Standard computer case form factor for modern computers.






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






20. Is a type of drive imaging. It duplicates data on one drive to another drive and is used for fault tolerance.






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






22. Windows Vista technology that supports a hybrid drive.






23. A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.






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






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






26. 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.






27. An ATAPI cabling method that uses a narrower and more reliable cable than the 80-conductor cable.






28. 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






29. 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:






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






31. 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






32. 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






33. 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.






34. 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.






35. 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.






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






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






38. 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.






39. 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
