1- Describe the following memory types: i) Primary Memory, ii) Secondary Storage. 2- Categorize the following memory technologies based of the two memory types "Primary memory" and "Secondary Storage". a) Cache memory b) Main memory c) Flash memory d) Solid State Disk e) CD f) DVD 3- Create a 2-column table to compare SRAM with DRAM memory. Indicate which class of memory (i.e., SRAM, DRAM) is used to build: i) Cache memory, ii) main memory. Explain why. 4- In a computer with 32-bit data-bus, how many 4-bit wide memory components is used? If the size of each 4- bit memory component is 4 x n cells where n = 1G (i.e., 4x n uniquely addressable locations-n: row, 4:2 column/width), what is the total capacity of the memory system? Show your answer in power of 2. (hint: 1000~ 210) 5- What is volatile memory? What is a non-volatile memory? 6- (True/False) Look at the table and answer the following questions: a) Size of SRAM is smaller than the size of DRAM. b) DRAM is faster to access compared to SRAM. c) DRAM is used to build Cache memory. d) Flash memory is slower that SRAM and DRAM. e) Flash memory is a volatile memory. f) SRAM is a non-volatile memory. Characteristic Static Volatile Typical size Organization Access time Application DRAM Static RAM Flash Memory No Yes Yes Yes Yes 256 Mbits 64 Mbits 4 bits 64 M 8 bits x 8 M 25 ns 2 ns Main store Cache memory No 256 Mbits 8 bits x 32 M 40 ns BIOS, digital film, MP3 7- Order the following memory technologies according to access time (from fast to slow), and then according to price (from expensive to cheap): Tape, L1 Cache, DVD, L2 Cache, Blu-Ray, main memory, CD, Registers, Hard Disk. Note that partial credits are not allowed for this question. 8- What is the reason for including L2 cache in computer's memory system? 9- What is a memory controller? Where is it normally located? What type of operations does it manage? 10- To compare storage technology, there are a few measures including durability, dependability, speed, capacity, and cost used to evaluating the storage options. Define each of the above measuring metric. (10 points) Then, pick two secondary storage technology of your choice and research the internet to compare their advantages and disadvantages according to the above metrics and show the result of your research in a 2- column table. You should also acknowledge your references. (20 points) 11- What are the main components of a magnetic hard disk? Describe each component. 12- Define the following concepts in the context of hard disks: a) Track b) Sector c) Access Time d) Data Transfer Rate 13-Consider a disk with a sector size of 512 B, 60 sectors per track, 1000 tracks per surface, and 5 single sided platters. The average seek time is 10 msec. Answer the following questions: a) What is the capacity of a track in bits? b) What is the capacity of each surface? c) What is the total capacity of the disk? d) If the disk platters rotate at 5400 rpm, what is the maximum rotational latency? 14- List and explain different types of solid state storage devices. 1- Describe the following memory types: i) Primary Memory, ii) Secondary Storage. 2- Categorize the following memory technologies based of the two memory types "Primary memory" and "Secondary Storage". a) Cache memory b) Main memory c) Flash memory d) Solid State Disk e) CD f) DVD 3- Create a 2-column table to compare SRAM with DRAM memory.
