Which two of the following describes the number of pins normally associated with dual inline memory modules(DIMMS)? select two...
- A.
30
- B.
72
- C.
144
- D.
168
- E.
184
Correct Answer(s)
D. 168
E. 184Explanation
Dual inline memory modules (DIMMs) are typically associated with 168 and 184 pins. DIMMs are used in computers to provide additional memory capacity. The number of pins on a DIMM determines its compatibility with the motherboard. The options 30, 72, and 144 are not commonly associated with DIMMs. Therefore, the correct answer is 168 and 184.Rate this question:
-

Which of the following memory modules must be installed in pairs?
- A.
72 pins SIMMs
- B.
168 pin DIMMs
- C.
184 pin DIMMs
- D.
184 pin RIMMs
Correct Answer
D. 184 pin RIMMsExplanation
184 pin RIMMs (Rambus Inline Memory Modules) must be installed in pairs because they use a technology called Rambus that requires a high-bandwidth connection between the modules. This high-bandwidth connection is achieved by using two modules in parallel, allowing for faster data transfer rates. Installing only one module would result in reduced performance and potential compatibility issues. Therefore, 184 pin RIMMs should always be installed in pairs to ensure optimal performance.Rate this question:

- D.
SODIMMs
Correct Answer
C. RIMMsExplanation
RIMMs, or Rambus Inline Memory Modules, have 184 pins and are 16 bits wide. RIMMs were a type of memory module used in computers during the late 1990s and early 2000s. They were designed to work with Rambus memory technology, which offered high-speed data transfer rates. RIMMs were mainly used in high-performance systems and were eventually phased out in favor of other memory technologies like DDR and DDR2.Rate this question:

From the following display types take up the lease space on the desk?
- A.
Terminal
- B.
LCD
- C.
CRT
- D.
LED
Correct Answer
B. LCDExplanation
LCD (Liquid Crystal Display) screens are known for their slim and compact design, which allows them to take up less space on a desk compared to other display types such as CRT (Cathode Ray Tube). CRT screens are bulky and require more desk space due to their large size and depth. LED (Light Emitting Diode) screens are also slim, but LCD screens are generally thinner and take up even less space. Therefore, LCD screens are the display type that takes up the least space on a desk.Rate this question:

After completing the installation of your internal and external SCSI devices that connects to an Adapted AHA-1542s SCSI adapter, you find that none of the devices works. Which of the following should you do first to try and fix the problem?
- A.
Disconnect all devices and start over
- B.
Remove the adapter and replace with a new one
- C.
Change the SCSI ID's
- D.
Enable termination on the adapter
Correct Answer
D. Enable termination on the adapterExplanation
Enabling termination on the adapter is the first step to try and fix the problem because termination is necessary for proper communication between SCSI devices. Terminating the adapter ensures that the electrical signals are properly terminated at the end of the SCSI chain, preventing signal reflections and data corruption. By enabling termination on the adapter, you are ensuring that the SCSI devices are able to communicate effectively and function properly.Rate this question:

Correct Answer(s)
A. Locate the red stripe on the cable, and connect the device with the red stripe lining up to pin #1
C. If there is also no red stripe, Locate the blue stripe on the cable, and connect the device with the blue stipe lining up to pin # 1Explanation
When installing an IDE device, it is important to connect the cable correctly. In this case, if the cable is not keyed, the correct approach is to locate the red stripe on the cable and connect the device with the red stripe lining up to pin #1. This ensures that the device is properly aligned with the correct pin. However, if there is no red stripe on the cable, the next step is to locate the blue stripe and connect the device with the blue stripe lining up to pin #1.

Correct Answer
C. Start the computer in Safe Mode and Roll Back the driverExplanation
When a technician upgrades the video drivers on a Windows XP computer and it fails to boot up properly, the first step should be to start the computer in Safe Mode. Safe Mode allows the computer to boot up with minimal drivers and services, which can help isolate and troubleshoot the issue. Once in Safe Mode, the technician can then roll back the video driver to the previous version. This can be done through the Device Manager or by using the System Restore feature. Reverting to the last known good configuration or running the Recovery Console may also be viable options, but starting in Safe Mode and rolling back the driver is the most straightforward solution.Rate this question:
