256 Yottabytes = ________ Bytes ?
A simple paging system has a memory size of 256 bytes and a page size of 16 bytes. i. What is the size of the page table? ii. How many bits exist for an address, assuming 1-byte incremental addressing? iii. State p and d values (i.e. the page number and the offset). iv. Perform address translation of 64 bytes to physical address space using the page table below. 0 8 1 6 2 3 3 11 4 7

Problem 6. Suppose we have a computer with 32 megabytes of main memory, 256 bytes of cache, and a block size of 16 bytes. For each configuration below, determine the memory address format, indicating the number of bits needed for each appropriate field (i.e. tag, block, set, offset). Show any relevant calculations. Direct cache mapping and memory is byte-addressable a) Direct cache mapping and memory is word-addressable with a word size of 16 bits b) c) 2-way set associative cache...
A primary memory system consists of 128 address bits. Each block within the cache is 256 bytes. The total cache size is 131,072 bytes. What are the sizes of the tag and index in the cache? First, find the number of blocks. 128,000 bytes # Blocks = 256 bytes per block bort = 512 blocks Where does the 128,000 come from?? Now find the number of bits required to distinguish all the blocks. This is the index aka set size....
What will be the size of storage, measured in bytes, needed to store a 16-second video at a 30-frame/second and a picture resolution of 256 by 256 pixels, assuming we are using a 24-bit RGB full color, with no compression.
A VM system uses segmentation with segment tables having maximum 256 entries and a maximum segment size of 4096 bytes. A section of the segment table is shown below, with all numbers expressed in hexadecimal (with the H suffix): What is the physical address expressed in base 16 for a hexadecimal virtual address of 2DAC0H? D0FFH BEEFAC0H 43500H 399AFH 2DC9AFH C9AFH
Assuming shorts are 2 bytes long, and pointers are 8 bytes long, how many bytes does this program need? short a = 3; short b = a; short * c = &a; *c = b++; short & d = a; short & e = b; short * f = c; e = *f + d; (a) 0 (b) 4 (c) 8 (d) 12 (e) 16 (f) 20 (g) 24 (h) 28 Please confirm. My answer: (f) 20 short a =...
How many bytes does a 64 KB microprocessor memory contain? Note: 1 KB = 2^10 bytes 1 MB = 2^20 bytes 1 GB = 2^30 bytes
has AES - 256 been cracked? How long would it take to crack AES- 256?
Consider a disk with block size = 4096 bytes. A block pointer is 6 bytes and a record pointer is 8 bytes long. A file has 100,000 records of fixed length. Each record has the following fields and byte size: Name (30), Ssn (9), Dept (9), Address (40), Phone (10), Bdate (8), Sex (1), Job (4) and Salary (4). An additional byte is used as a deletion marked. a. Calculate the record size R in bytes b. Calculate the blocking...
