question
Your motherboard has sockets for 184-pin DIMM RAM. Which type of RAM should you install?
answer
DDR.
Explanation: The type of RAM you should install depends on what type of motherboard you have. If you have a 184-pin DIMM socket, then you should install DDR RAM.
question
What is the approximate bus speed of DDR2 memory rated at PC2-5300?
answer
333 MHz.
Explanation: DDR2 memory rated at PC2-5300 has an approximate bus speed of 667 MHz.
question
Assuming the same operating frequency, what are the advantages of DDR3 over DDR2?(Select TWO)
answer
1. DDR3 uses less power than DDR2. 2. DDR3 doubles the data transfer rate of DDR2.
Explanation: DDR3 has lower power consumption and a higher data transfer rate than DDR2.
question
Which of the following memory rating identifies the fastest memory?
answer
DDR3-1600.
question
Which memory rating identifies the fastest memory?
answer
DDR3-2000.
Explanation: The fastest memory is typically identified by the highest memory rating. For example, DDR4-3200 is faster than DDR4-2133.
question
Which of the following BEST describes the theoretical capacity of a DDR4
answer
512 GB.
Explanation: -2400 SO-DIMM?The theoretical capacity of a DDR4-2400 SO-DIMM is 8 GB. This is because a DDR4 SO-DIMM has a capacity of 64 Gb (gigabits), and a DDR4-2400 SO-DIMM has a data rate of 2400 MT/s (megatransfers per second). Therefore, the capacity of a DDR4-2400 SO-DIMM is 8 GB.
question
Assuming the same operating frequency, what advantages does DDR4 have over DDR3(Select TWO)
answer
1. DDR4 Doubles the data transfer rate of DDR3. 2.DDR4 uses less power than DDR3.
Explanation: DDR4 has a higher data rate than DDR3.DDR4 uses less power than DDR3.DDR4 has a lower latency than DDR3.DDR4 has a greater memory capacity than DDR3.
question
Which of the following are terms used to identify memory modules?
answer
DIMM.
Explanation: The terms used to identify memory modules are DIMM, SIMM, and RIMM. DIMM is an acronym for dual in-line memory module. SIMM is an acronym for single in-line memory module. RIMM is an acronym for Rambus in-line memory module.
question
A customer needs to use several applications. Currently, the computer cannot keep all the necessary applications open at the same time. which of the following components should you consider upgrading?
answer
Memory.
Explanation: If a customer needs to use several applications at the same time, they may need to upgrade their computer's processor, memory, or storage.
question
Drag the memory modules shown in the image below Drag the label on the left and drop it on the letter on the right that best identifies the associated memory module form.
answer
A. DDR DIMM. B. DDR3 DIMM. C. DDR4 DIMM. D. DDR2 DIMM E. 200-pin SODIMM. F. 144-pin SODIMM. G. UniDIMM.
Explanation: The image shows different types of memory modules. The labels on the left identify the type of module, while the letters on the right identify the form factor of the module.DIMM: A DIMM (dual in-line memory module) is a type of memory module that uses a 64-bit data path. DIMMs are used in computers that use the SDRAM (synchronous dynamic random-access memory) memory type.SO-DIMM: A SO-DIMM (small outline dual in-line memory module) is a type of memory module that uses a 72-bit data path. SO-DIMMs are used in laptops and other small computers that use the SDRAM memory type.RIMM: A RIMM (registered in-line memory module) is a type of memory module that uses a 184-bit data path. RIMMs are used in servers and other high-end computers that use the DDR (double data rate) memory type.SIMM: A SIMM (single in-line memory module) is a type of memory module that uses a 32-bit data path. SIMMs are used in older computers that use the SDRAM memory type.

question
Which of the following is an upgrade to the SODIMM standard?
answer
UniDIMM.
Explanation: The following is an upgrade to the SODIMM standard:The new standard, called SO-DIMM+ (or SO-DIMM Plus), is an extension to the existing SODIMM standard that adds support for a wider range of memory modules, including those with higher capacities and faster speeds. The SO-DIMM+ standard is also backward-compatible with existing SODIMM modules, so it can be used in existing devices.
