Answer question 18, 19, 20 showing fully all the steps. Solution should be perfect(very correct), clear, brief and explicit enough!

D. Radio waves A network interface card(NIC) is found A. In every network end-device (host) B. In the server only C. In the router 21. If memory access takes 20 ns with cache and 110 ns without it, then utility rate of the cache is approximately A. 80% B. 90% C. 82% D. 84% 22. Cache memory acts between A. CPU and RAM B. RAM and ROM 15. D. At the terminal of every transmission_ medium In memory hierarchy, the larger the memory the E. Higher the access time and the higher the speed of transfer of data to CPU F. Higher the access time and the lower the speed of transfer of data to the CPU G. Shorter the access time and the higher the speed of transfer of data to CPU H. Shorter the access time and the lower the speed of transfer of data to CPU 16. C. CPU and Hard Disks D. None of these 23. generally Dynamic RAM is used as main memory computer system as it A. consumes less power B. has higher speed C has lower cell density D. needs refreshing circuitry Logic X-OR operation of (11101010)2& (10101010)2 has as results A. 10010001 B. 01100000 C. 10000000 D. 10000000 (-27)10 can be represented in a signed magnitude format and in a 1's complement format as E.
