Test Out 3.8.8

You want to build a new system that supports 6 GB of memory
Explanation: A 64-bit processor is a central processing unit (CPU) that has the ability to work with data that is 64 bits wide. A 64-bit processor can process twice as much data as a 32-bit processor.The first 64-bit processors were released in 2003. They were used in servers and high-end workstations. Today, 64-bit processors are used in all types of computers, including desktop, laptop, and tablet computers.

What type of RAM might slow system performance because it holds memory addresses or data to improve stability on systems with more than 1 GB of RAM before it is transferred to the memory controller?
Explanation: Reader, PrintWriterBufferedReader is a Java class that allows a programmer to read text from a character-input stream. A BufferedReader reads characters from a character-input stream into a buffer. It can be used to read data from a file, an array, or a String.PrintWriter is a Java class that allows a programmer to write characters to a character-output stream. A PrintWriter writes characters to a character-output stream, such as a file, an array, or a String.

With a memory module read request, there is a delay between the time of the data request and the time the data is available for output from the memory module.
Explanation: CAS latency is the delay between the time at which a memory controller tells the memory module to access a particular column in a row of data, and the time at which the data from that column is available on the module's output pins. CAS stands for Column Address Strobe.

You have a computer that has four DDR2 memory slots. Currently there are two 512 MB memory modules installed. You check the motherboard documentation and find that the system has a 4 GB memory limitation. You want to add as much memory as possible without replacing the existing modules. What is the maximum total amount of RAM that can be installed on this system?

Which of the following statements is true regarding single and double-sided memory?
Explanation: Single sided memory modules have one side that is blank, while double sided memory modules have information stored on both sides. Therefore, it takes twice as many single sided memory modules to store the same amount of information as double sided memory modules.

A new computer is being purchased for Peter, the new administrative assistant. Peter uses word processing, spreadsheets, presentation software, and a web browser to complete his job assignments. Which of the following best describes the reason to choose unbuffered instead of buffered memory for this new computer?
Explanation: Buffered memory is typically more expensive than unbuffered memory because it includes an additional buffer chip that helps improve performance. The buffer chip helps to improve data transfer speeds and can also help to improve data integrity. However, the trade-off is that buffered memory is typically slower than unbuffered memory.

You work as the IT administrator for a small corporate network. Sam, an employee in the support department, wants to run a virtual machine on his computer to troubleshoot customer issues from, and he needs a very stable computer from which to work. You need to decide whether to install buffered or non-buffered RAM in his computer. Which of the following best describes the reason to choose buffered instead of un-buffered memory for this new computer?
Explanation: .Buffered memory is a type of computer memory that uses a buffer to improve speed and reliability. The buffer is a small area of fast memory that holds a copy of the data that is being read from or written to the main memory. When the data is read from or written to the buffer, it is transferred to or from the main memory at a much slower speed.Buffered memory reduces the load on the memory controller by providing a small, fast area for the controller to access. This allows the system to be more stable and reduces the chance of errors.

Paul has just joined your company, and you are in the process of purchasing a laptop computer for his use. Paul will work as a sales rep in the sales department. You have heard that some types of RAM are better than others. Which of the following types of RAM would best meet the needs of Paul's new computer?
Explanation: for most desktop computersNon-ECC memory is less expensive because it does not use error-correcting code (ECC) to detect and correct memory errors. Parity is not required for most desktop computers because they do not typically have more than one memory module installed, and because the error-detection and correction capabilities of the computer's processor are typically sufficient to handle any memory errors that may occur.

You have an existing system that has a single DDR3 memory module installed. You would like to add more memory to the three remaining empty memory slots. What should you do to make sure you get the right memory for the system?
Explanation: 3.) Remove the current modules and insert the new modules into the same slots 4.) Install the new modules in different slots1. Check the motherboard documentation to find which modules are supported. This will ensure that you purchase the correct type of RAM for your motherboard.2. Purchase additional modules that are the same as what is currently installed. This will ensure compatibility with your current setup.3. Remove the current modules and insert the new modules into the same slots. This will ensure that the new modules are properly seated and that the old modules are removed.4. Install the new modules in different slots. This will allow you to use all of the available slots on your motherboard and will provide the best performance.

Which of the following are true regarding a dual-channel memory bandwidth configuration?
Explanation: 3.) Latency is decreased by 5-15%1. Dual-channel support means that the memory controller can handle two separate channels of data, effectively doubling the amount of data that can be transferred at any given time. This is a significant increase in bandwidth and is especially important for applications that require large amounts of data to be transferred quickly, such as video streaming or gaming.2. The increased bandwidth provided by dual-channel support can result in a 5-15% increase in overall system performance. This is due to the fact that more data can be transferred in a given period of time, allowing for quicker access to information and shorter wait times.3. The decreased latency associated with dual-channel support can also lead to a 5-15% increase in system performance. This is because less time is required for the memory controller to access data from the memory, resulting in quicker response times and improved performance.

You are in a carpeted office lighted by fluorescent bulbs. You are preparing to add memory modules to a user's copmputer. The user has already unpacked the memory modules and stacked them on top of an old, unused CRT monitor. In this environment, what is the greatest threat to these memory modules?

You have a computer with a Pentium 4 CPU and two PC-2400 DDR modules. The motherboard has room for two additional memory modules and you'd like to install two PC-4000 modules. Which of the following statements is true?
Explanation: The question is asking for an explanation of the statement All memory will operate at 300 MHz." This means that all of the computer's memory (including RAM, ROM, and cache memory) will operate at a speed of 300 MHz. This is a relatively fast speed for memory, and it means that the computer will be able to access and store data quickly."

Which of the following is the most common method for removing RAM from a motherboard?
Explanation: .To remove the RAM from your computer, first find the tabs on the side of the RAM that are holding it in place. Then, pull straight up on the RAM to remove it from the computer.

You want to upgrade all memory in your system with the fastest memory available. Which of the following should you choose?
Explanation: is determined by the chipset that is used.The type of memory that is supported by your motherboard is determined by the chipset that is used. The chipset is the heart of the motherboard and is responsible for managing all of the data that flows through the board. There are a variety of different chipsets available on the market, and each one supports a different type of memory.The most common type of memory supported by chipsets is DDR3. This is the latest generation of memory and is very fast. It is also very energy efficient, which is why it is the most popular choice for new motherboards. Other types of memory supported by chipsets include DDR2, DDR, and SDRAM.
