Convert the following from hex to binary and draw it on the memory map.
RAM = 0000 -> 00FF EPROM = FF00 -> FFFF
Answer:
0000 0000 0000 0000 (0) RAM start
0000 0000 1111 1111 (255 byte) RAM stop
1111 1111 0000 0000 (63.75K) Eprom start
1111 1111 1111 1111 (64K) Eprom stop The memory map is shown below:-
Due to the tri-state nature of the I.C's (Ram, Rom etc.) they may be placed in parallel and 'turned on ' when they are required. This process is termed decoding. There are two types of decoding:- 1. Partial decoding 2. Absolute decoding

1. Suggest some mechanism(s) to lower the dispatch latency while scheduling for a real-time system. Also, discuss any trade-off or consequent constraint associated with it, if a
Since each thread has its own processing space therefore communication between threads will need to be done through a common global variable. Since multiple threads can access the

Q. Segmentation is alike to paging but uses variable-sized "pages". Describe two segment-replacement algorithms based on FIFO and LRU page replacement schemes. Remember that since
1. On every access, mark the page with a timestamp. Whenever we need to evict a page, we search through memory for the oldest page, the least-recently used page. But we need memory
Q. Explain about Spooling? Acronym for simultaneous peripheral operations on line. Spooling denotes to putting jobs in a buffer, a special area in memory or on a disk where
how does it works
A- Consider a computer system that provides a virtual memory space that consists of 8 pages. The physical memory contains 4 pages where the page size is 4Kbytes. Assume that at sp
Construct a process tree similar to Figure 1. Look up the Linux command pstree -p and describe what it does. Then type in the command the capture the output.
