Comptia A + Certification

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 T-1 multiplexer or a special LAN bridge that connects to the telephone company's channel service unit (CSU) - which encodes data for transmission over a T-carrier circuit.






2. A file used by Windows for virtual memory. Also called the swap file. The actual filename in Windows is PAGEFILE.SYS.






3. A DVI mode that supports digital video signals and is partially compatible with HDMI. Aka also digital video interface and High-Definition Multimedia Interface.






4. Local area networking using radio waves that includes several implementations based on the IEEE 802.11 group of standards.






5. A type of printer that transfers ink to paper by causing a print head to strike a printer ribbon containing ink against the paper.






6. Memory that is accessible in any (random) order. Most of the memory in a PC is RAM.






7. A more advanced and more expensive alternative to a port replicator. In addition to the ports normally found on a port replicator - a docking station may include full-size expansion slots and drives.






8. Aka complementary metal-oxide semiconductor.






9. In networking - this is a set of rules for using network hardware and software. In most discussions about networks - this term is assigned to certain network software components.






10. A tool for testing if a cable can connect properly end-to-end and to determine if a cable has a short. These tools are available for a variety of cable types.






11. A network connection device that routes IP packets between networks.






12. A standards organization - of which the T10 SCSI committee maintains the SCSI standard.






13. Aka double-data rate (DDR) SDRAM.






14. Aka double-data rate (DDR) SDRAM.






15. A network connection device that passes traffic between two networks - using the physical address (MAC address) of the destination device.






16. A tool for migrating user data and settings from one Windows computer to a computer running Windows XP.






17. In reference to a memory module - the number of memory modules required to match the data bus width of the processor.






18. Aka pointing stick.






19. Aka systray.






20. An optical semiconductor used in small projectors and in rear-projection televisions.






21. Aka error-correcting code.






22. The top-level folder or directory in the file structure. This appears the same - regardless of the underlying file system.






23. Aka nickel metal hydride.






24. The first type of RAM available. It is very fast - compared to DRAM - but also very expensive.






25. This attack occurs when someone sends a large number of requests to a server - overwhelming the server so it stops functioning on the network.






26. Aka master boot record.






27. Radio frequency interference. Radio signals that occur in proximity to equipment that is sensitive to these types of signals.






28. A laptop is a small - easily transported computer - generally weighing less than 7 pounds and with roughly the same dimensions as a 1- to 2-inch-thick stack of magazines. Laptops computers have an all-in-one layout in which the keyboard - and often t






29. Aka systray.






30. A plug designed for testing a specific port type (e.g. - serial - parallel - or USB). The plug does not connect to a cable but reroutes the sending pins to the receiving pins. Using special software on the computer - a loopback test is performed in w






31. A file system in which one of the basic structures is a table used for allocating space. This table is called the file allocation table (FAT).






32. The default Windows file system that includes many important features - including encryption and permissions.






33. Light waves in the infrared spectrum.






34. An action - such as the CTRL-ALT-DELETE key combination or the insertion of a smart card - that clears memory of certain types of viruses before a user logs on.






35. [1] A device that is the central connecting point of a LAN. A hub is little more than a multiport repeater taking incoming signals on one port and repeating them to all other ports. Ethernet hubs have been largely replaced by Ethernet switches.. [2]






36. Aka file allocation table.






37. A diagram showing the purpose of each wire in a connector.






38. A RAM standard that replaces the original DDR2 standard and requires far less power - while providing almost twice the bandwidth. A stick of DDR3 SDRAM has 240 pins - but is keyed so it will not fit into a socket designed for DDR2. DDR3 SO-DIMMs have






39. An interface standard developed by the American National Standards Institute (ANSI) - it is used for both internal and external hard drives and optical drives as well as devices such as printers - modems - scanners - and many other peripherals.






40. A firewall consisting of software that you can install on any computer - as opposed to the software built into a hardware firewall. Also called personal firewalls because they are designed to be installed on individual desktop computers.






41. In a CPU - special memory that resides within the CPU's core and is used to temporarily store instructions and data in order to increase the processing speed. Also called L1 cache.






42. A computer display that uses liquid crystal or plasma technology and does not require the bulk of a large picture tube. The screen enclosure can be as thin as one to two inches.






43. Aka single inline memory module.






44. A service implemented on Windows Servers that hides the complexity of the network from end users in that it makes files that are distributed across multiple servers appear as if they are in one place.






45. A wireless network standard that uses the 2.4 GHz band at a speed of up to 54 Mbps. It is downward-compatible with 802.11b.






46. Pertaining to a DVD drive and disc that can store data in two pitted layers on each data side - with each layer having a different reflectivity index.






47. Cable that consists of pairs of wires twisted around each other. The twists help to boost each wire's signals and make them less susceptible to electromagnetic interference (EMI).






48. A Windows server running the WINS service to maintain and resolve NetBIOS names.






49. Aka Video Electronics Standards Organization.






50. A wireless data encryption standard based on the IEEE 802.11i security standard. It issues keys per-user and per-session and includes encryption key integrity checking. It uses Temporal Key Integrity Protocol (TKIP).
