- *:The base address exists on EU only. O Both BIU and EU. O None of these. O RAM only. O BIU only. O Stack memory only. O ROM only. O هذا السؤال مطلوبQ1: Answer the following as true or false Data are transferred to and from memory in groups of bits called words. Due to space and cost constraints, there is a unlimited number of registers in a CPU. Cache Memory It is basically fast memory device, Generally, the least recently used information is kept in the cache memory. The CPU can work with the information available in main memory only. Semiconductor memories are volatile in nature. It loses its content once we switch off the computer. DRAM is Slower and cheaper than SRAM. Basic Input Output System used to start up the operating system. It is stored on computer chip in a way that causes the data to remain even when power is turned off. PROM Programmable Read Only Memory; it can be programmed once as per user requirements. EPROM Programmable Read Only Memory; it can be programmed once as per user requirements.With virtual memory, when a program requests memory,the memory management system does which of the following? Select one: A. It grants the request as long as there is enough physical memory to accommodate B. It looks up the address in the page table. If the address is in memory, then it grants the request. C. It looks up the address in the page table. If the address is in memory, it grants the request. If the address is stored to disk, it writes a section of memory to disk and then transfers the requested virtual memory address from disk to main memory. D. It causes a deadlock to occur.
- Memory Management: Select all of the following statements that are true. The memory management unit (MMU) maps virtual to physical addresses. When using a single-partition allocation scheme, the main memory is divided into two partitions. The frame table that is applied in systems that use paging is a per-process data structure. Indirect relative addressing refers to an addressing scheme in which the memory address to be accessed is specified explicitly. Segmentation is a memory management approach in which memory areas (segments) allocated to processes are defined by their starting address (base) and length."Non-uniform memory access" means what?Which of the following refers to the associative memory? A. the address of the data is generated by the CPU B. the address of the data is supplied by the users C. there is no need for an address i.e. the data is used as an address D. the data are accessed sequentially E. None of the above
- 20. Which of the following statements is true of memory sizes? a. A 3 kb memory has 3000 memory bits b. A 16 × 4 memory has 64 words c. A 4 kb memory has 4096 memory bits d. A 32 × 16 memory has 16 words 21. Which of the following statements about cache is NOT true? a. A cache typically resides on-chip with the processor. b. A cache is faster and has higher capacity than memory. c. A cache hit means that an item is found in the cache. d. SRAM is faster than DRAMMethods of Operation: Now we'll dive further into the four memory allocation techniques introduced throughout the rest of the course and explain how they work. Please explain which two of these four terms are used most often in everyday speech.What the content of memory location 2001H after executing the following program if content of location 2000OH = 05H?
