How is the motherboard to be used? (For example, it might be used for light business and personal use,as a gaming system, for a server, or for a high-powered workstation.)Knowing how the board will be used helps you decide about the most important features and overallpower of the board. For example, a motherboard to be used in a server might need support for RAID(an array of multiple hard drives to improve performance and fault tolerance). In another example,a motherboard used in a gaming system will not need RAID support, but might need a chipset thatsupports two high-end graphics adapters.
If an SSD can withstand 1 billion analogue cycles, how long will a 1 TB SD drive endure if you write 10 50 GB files every day?
Which level of RAID uses disk mirroring and is considered fault-tolerant? a. Level 1 b. Level 2 c. Level 3 d. Level 4

- Janira bought an M.2 drive because someone told her it is the fastest technology available and his motherboard supports it. Upon testing her drive, Janira realizes that it doesn't go beyond 6GBPS as his old 2.5 inch SSD drive. What could the problem be? Explain clearly.arrow_forwardWhich RAID level uses a mirror (shadow) set?arrow_forwardWhich RAID level uses a mirror (shadow) set, and which doesn't?arrow_forward
- What type of I/O (memory-mapped or Port) does the SAMD21 M0+ on the Sparkfun Mini Breakout use? Explain how it relates to each type of I/O scheme.arrow_forwardSuppose the daytime processing load consists of 60% CPU activity and 40% disk activity. Your customers are complaining that the system is slow. After doing some research, you learn that you can upgrade your disks for $8,000 to make them 2.5 times as fast as they are currently. You have also learned that you can upgrade your CPU to make it 1.4 times as fast for $5,000. Q.Which option would you choose if you don’t care about the money, but want a faster system?arrow_forwardA company that has engaged in a business that requires fast response times has just received a bid for a new system that includes much more storage than was specified in the requirements document. When the company questioned the vendor about the increased storage, the vendor said he was bidding a set of the smallest-capacity disk drives that the company makes. Why didn’t the vendor just bid fewer disks?arrow_forward
- Describe what wear leveling is and why it's essential for solid-state drives in your own words. According to what was said in the prior conversation, wear leveling is an essential component of the ongoing process of upgrading the pagefiles that make up virtual memory. What is the problem that is made worse when wear leveling is applied to pagefiles?arrow_forwardInput sought on the following. The motherboard's dual-channel architecture makes room for four different DIMM sizes. The motherboard supports all four of these formats. Do these DIMMs work with the motherboard? Will dual-channel support be available?Since you have 4 GB of RAM total (two 2 GB modules), your motherboard should support dual channelling. You've made the choice to install an extra 4GB of memory. To maximise performance, you should install either one 4GB DIMM or two 2GB DIMMs. Defend your stance.arrow_forwardUse the Internet to gather information on three different commercial hardware RAIDcontrollers that perform RAID level 5, and write a short report that compares and contraststheir features and cost. In what situations would you use each one?arrow_forward
- In comparison to alternative methods of storing configuration data like jumpers or switches, what makes you believe CMOS RAM is the best option?arrow_forwardQuestion 5 In a DRAM chip, the row buffer capacity is 4KB. How many DRAM clock cycles will it take to transfer 1KB data using a burst mode with a 64-byte cache block/line and a memory that can transfer 64-bit data over the bus? Assume the row is always pre-charged. Hint: Add the precharge cycles every time a row buffer is closed, recall row buffer acts as a small cache. Assume: -5 cycles to send row address (page open or RAS) -1 cycle to send a column address -3 cycle DRAM access latency -1 cycle to send data -5 cycles to send precharge (page close)arrow_forwardWhich bus-synchronous or asynchronous-is preferable for connecting the CPU to the memory? A defense is required.arrow_forward
