⭐⭐⭐MOST REPEATED QUESTIONS ⭐⭐⭐ Long Questions [7/10 marks question] Q1) Discuss the Memory Hierarchy in computer system with regard to Speed, Size and Cost. Q3) A computer uses RAM chips of 1024 * 1 capacity i.) How many chips are needed and how should their address lines be connected to provide a memory capacity of 1024 * 8? ii.) ii. How many chips are needed to provide a memory capacity of 16 KB? Explain in words how the chips are to be connected to the address bus. Q4) Consider a cache (M1) and memory (M2) hierarchy with the following characteristics: M1: 16K words, 50 ns Access time M2: 1M words, 400 ns Access time Calculate the effective memory access time with a cache hit ratio = 0.95. Q5) A digital computer has a memory unit of 64K × 16 and a cache memory of 1K words. The cache uses direct mapping with a block size of four words. I. How many bits are there in the tag, index, block, and word fields of the address format? II. How many bits are there in each word of cache, and how they are divided into functions? Include a valid bit. III. How many blocks can the cache accommodate? Q6) Explain the direct mapping technique. Q7) Consider a cache consisting of 256 blocks of 16 words each for a total of 4096 words and assume that the main memory is addressable by a 16-bit address and it consists of 4K blocks. How many bits are there in each of TAG, SET, WORD field for 2-way set associative technique? Q8) Calculate the page fault for a given string with the help of LRU and FIFO page replacement algorithm. Size of frames = 4 and string 1 2 3 4 2 1 5 6 2 1 7 6 3 2 1 3 6. Q9) Explain auxiliary memory. What are the commonly used auxiliary memory? OR Write a short note on magnetic disk, magnetic tape, and optical disk. Q10) The logical address space in a computer system consists of 128 segments. Each segment can have up to 32 pages of 4K words each. Physical memory consists of 4K blocks of 4K words each. Formulate the logical and physical address formats. Q11) How is the Virtual address mapped into physical address? What are the different methods of writing into cache? Q12) Give classification of memory based on the method of access. Also discuss construction and working of magnetic disk and various components of disk access time. ⭐⭐⭐MOST REPEATED QUESTIONS ⭐⭐⭐ Very Short Questions [2 marks question] Q1)Differentiate between static RAM and Dynamic RAM.
