The correct answer is SDRAM. SDRAM stands for Synchronous Dynamic Random Access Memory. It is a type of memory module commonly used in personal computers. In this scenario, the PC is installed with a Pentium processor and a PC100 memory module, which indicates that it uses SDRAM. SDRAM is a type of memory that synchronizes with the computer's bus speed, allowing for faster data transfer and improved performance.Rate this question:

Correct Answer(s)
A. PC66
B. PC100
C. PC75
D. PC83
E. PC133Explanation
The correct answer is PC66, PC100, PC75, PC83, and PC133. These are all different speeds of SDRAM modules that are available. PC66, PC100, and PC133 are commonly used speeds for SDRAM modules, while PC75 and PC83 may be less common but still available options.Rate this question:

What do you need to know when buying SDRAM memory modules? Choose all that apply.
- A.
The operating system version.
- B.
The speed of the FSB.
- C.
The available memory module drivers.
- D.
The number of pins on the memory module.
- E.
The memory capacity the systemboard supports.
Correct Answer(s)
B. The speed of the FSB.
D. The number of pins on the memory module.
E. The memory capacity the systemboard supports.Explanation
When buying SDRAM memory modules, it is important to consider the speed of the FSB, the number of pins on the memory module, and the memory capacity that the systemboard supports. The speed of the FSB determines the maximum data transfer rate between the memory and the processor. The number of pins on the memory module must match the corresponding slot on the motherboard for proper installation. The memory capacity supported by the systemboard determines the maximum amount of memory that can be installed and utilized by the system.Rate this question:

You installed a PC83 memory module in a system with a 100MHz FSB. But the system doesn't boot. What could be the problem?
- A.
You installed a memory module with a speed lower than the FSB. You need to install a memory module with the same speed or higher than the FSB.
- B.
You installed a memory module with a speed higher than the FSB. You need to install a memory module with the same speed or lower than the FSB.
- C.
The memory module you installed is faulty.
- D.
The memory module is installed in a wrong slot.
- E.
You installed DDR-SDRAM module in the SDRAM slot.
Correct Answer
A. You installed a memory module with a speed lower than the FSB. You need to install a memory module with the same speed or higher than the FSB.Explanation
The system doesn't boot because the memory module installed has a speed lower than the FSB. The FSB (Front Side Bus) determines the speed at which the processor communicates with the memory. In order for the system to function properly, the memory module needs to have the same speed or higher than the FSB. Since the installed memory module has a lower speed, it is not compatible with the system and causes it to fail to boot.Rate this question:

Which SDRAM SODIMM memory modules are available for laptops? Choose all that apply.
- A.
72-pin
- B.
144-pin
- C.
200-pin
- D.
168-pin
- E.
184-pin
Correct Answer(s)
A. 72-pin
B. 144-pin
C. 200-pinExplanation
SDRAM SODIMM memory modules are available in different pin configurations to fit different types of laptops. The options provided include 72-pin, 144-pin, and 200-pin modules, which are commonly used in laptops. These modules have different physical sizes and pin layouts to ensure compatibility with the specific laptop models. The 168-pin and 184-pin options are not applicable for laptops as they are used in different types of memory modules.Rate this question:

What does RDRAM stand for?
- A.
Random Dynamic Rambus Access Memory
- B.
Rambus Dynamic Real Access Memory
- C.
Rambus Dynamic Rate Access Memory
- D.
Rambus Dynamic Random Access Memory
- E.
Real Dynamic Rambus Access Memory
Correct Answer
D. Rambus Dynamic Random Access MemoryExplanation
RDRAM stands for Rambus Dynamic Random Access Memory. Rambus is a type of memory technology that was developed by the company Rambus Inc. It is a type of dynamic random access memory (DRAM) that uses a high-speed bus to transfer data between the memory and the computer's processor. RDRAM was popular in the late 1990s and early 2000s, but it was eventually replaced by other memory technologies such as DDR SDRAM.Rate this question:
