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. Aka dual inline memory module (DIMM).






2. Aka Domain Name Service.






3. A type of computer firmware that is responsible for informing the CPU of installed devices and how to communicate with them.






4. A virus that gains access to a computer by masquerading as a harmless program that a user innocently installs on the computer.






5. The wireless nodes (including the WAP) communicating together in infrastructure mode.






6. A remote KVM switch that uses either Cat 5 or USB cabling. The distance it can be from the computers it controls is a function of the length limits of the cabling; it normally uses a proprietary protocol and special hardware.






7. A DVI mode that supports downward compatibility with analog displays.






8. An icon that represents a link to any object that an icon can represent. Activating a shortcut (by double-clicking it) is a quick way to access an object or to launch a program from the desktop without having to find the actual location of the object






9. A strap designed to discharge static electricity from your body. One end attaches to the wrist - whereas the other end attaches to a grounded object.






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






11. A storage type in Windows that uses the partition table in the master boot record (MBR) to define disk partitions.






12. A protocol used to resolve an IP address to a MAC address.






13. 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).






14. A paid television subscription service offered by cable television providers.






15. The signal in a television transmission that contains the brightness of the image.






16. A magnetic storage device that stores data on metal platters that have a coating that holds data in the form of changes to small magnetic particles in the coating. Also called HDD.






17. Aka solid-state storage.






18. A device used with a laptop. The port replicator remains on the desktop with external devices connected to ports on it. A laptop then needs only one connection to the port replicator to have access to the peripherals.






19. The amount of time it takes a packet to travel from one point to another.






20. Aka Windows Internet Naming Service.






21. A connector that is slightly larger than an RJ-11 connector and contains eight wires. RJ-45 connectors most commonly attach twisted-pair cables to Ethernet network cards.






22. A file attribute assigned to a file by the operating system to identify it as a system file.






23. Aka complementary metal-oxide semiconductor.






24. A hard drive interface that transfers data in parallel. EIDE and ATAPI drives attach to the PATA interface.






25. A device used to scan smart cards.






26. Any power supply that provides high voltage - such as those in laser printers and CRTs.






27. A Windows folder that contains numerous applets you can use to adjust the configuration of many different aspects of the OS.






28. An external bus that connects into the PC's PCI bus. With USB - you can theoretically connect up to 127 devices to your computer.






29. A device that takes video output and projects it onto a screen for viewing by a larger audience.






30. One of the main protocols of the TCP/IP protocol suite - IP manages logical addressing of network packets so routing protocols can route the packets over the network.






31. A virtual communication circuit that is created and remains available between two endpoints - which are normally some form of data terminal equipment (DTE). Telecommunications companies provide PVC service to companies requiring a dedicated circuit b






32. A cable medium that transmits light pulses rather than electrical signals - so it is not susceptible to electromagnetic interference (EMI).






33. Aka DDR3 SDRAM.






34. A network that covers a metropolitan area - usually using high-speed fiber-optic cable (operating in the gigabits-per-second range).






35. A private internetwork.






36. Aka Media Access Control (MAC) address.






37. A chip that works with a serial port - converting outgoing data from parallel to serial and incoming data from serial to parallel.






38. In the laser printing process - a blade that removes residual toner from the drum.






39. An LCD display using an old technology that has a grid of horizontal and vertical wires with a transistor at the end of each wire. When two transistors (one at the x-axis and one at the y-axis) send voltage along their wires - the pixel at the inters






40. Aka accelerated graphics port.






41. A network in which all of the computers essentially operate as both servers (providing access to shared resources) and clients (accessing those shared resources).






42. One of several groups that no user can create or modify. The membership of a special group is predefined - and it is available to you only when you assign permissions or rights. A few important special groups are Creator Owner - System - and Everyone
