• Question 77:

  You are selecting memory to put in to a laptop.

  Which of the following types of RAM chips would you most likely select?

  A. 144 PIN

  B. 72 PIN

  C. 240 PIN

  D. 184 PIN

  Correct Answer: A

  Both MicroDIMM and SO-DIMM come in a 144 pin configuration, and are used for laptops.

  What is SO-DIMM?

  Small Outline Dual Inline Memory Module (SO-DIMM) is a type of memory module that comes in 72 pins and 144 pins. The 72-pin SO-DIMM supports 32-bit transfers, and the 144-pin SO-DIMM supports 64-bit transfers. It was introduced for

  laptops. SO DIMMs come in smaller packages, consume lesser power, but are more expensive than DIMMs. Answer option B is incorrect. The 72-pin is a legacy chip used in PC's. Answer option D is incorrect. The 184-pin is used in DDR

  RAM in PC's. Answer option C is incorrect. The 240-pin is used in DDR2 and DDR3 RAM in PC's.

  What is DDR3 SDRAM?

  DDR3 SDRAM or double-data-rate three synchronous dynamic random access memory is a random access memory interface technology used for high bandwidth storage of the working data of a computer or other digital electronic devices.

  DDR3 is part of the SDRAM family of technologies and is one of the many DRAM implementations. DDR3 SDRAM is an improvement over its predecessor, DDR2 SDRAM, and the two are not compatible. The primary benefit of DDR3 is the

  ability to transfer at twice the data rate of DDR2, thus enabling higher bus rates and higher peak rates than earlier memory technologies. DDR3 memory power consumption is 30% less as compared to DDR2 modules.

• Question 78:

  You have a 2.8 Ghz Pentium 4 desktop computer running Windows 2000 Server operating system.

  You want to disable the hyper-threading on the computer. How will you disable the hyper- threading on the computer?

  A. Disable hyper-threading from the Computer Management utility.

  B. Disable hyper-threading using jumper setting on the motherboard.

  C. Disable hyper-threading from the Device Manager utility.

  D. Disable hyper-threading from the Basic Input/Output System (BIOS).

  Correct Answer: D

  Hyper-threading can be disabled on the computer from the Basic Input/Output System (BIOS).

  Hyper-threading is a technology developed by Intel. It is used to improve parallelization of computations performed on computer microprocessors via simultaneous multithreading. It provides support for multi-threaded code and allows multiple

  threads to run simultaneously and improved response time. A microprocessor with hyper-threading feature is treated by the operating system as two processors instead of one. Answer option C is incorrect. There is no such facility to disable

  hyper-threading from the Device Manager utility.

  What is Device Manager? Hide

  Device Manager is a tool that can be used to manage devices on a computer. Using Device Manager, users can view and change device properties, update device drivers, configure device settings, and uninstall devices. Device Manager is

  organized in a tree format with the top branches representing device categories. Users can use

  Device Manager to identify port resource conflicts. Device Manager can also be used to enable or disable a device.

  Answer option B is incorrect. There is no such facility to disable hyper-threading using jumper setting on the motherboard.

  Answer option A is incorrect. There is no such facility to disable hyper-threading from the Computer Management utility.

  What is Computer Management? Hide

  Computer Management is a component that is used to view and control many aspects of the computer configuration. It combines several administration utilities into a single console tree. Computer Management provides easy access to the

  local or remote computer's administrative properties and tools.
