Design a combinational circuit with 4 binary inputs w, x, y, z, and n binary outputs, a, b, c, ,represented by n bits . a is the most significant output bit and w is the most significant input bit. when the decimal value of the binary input bits (w xyz) is > 11 and < 14,the decimal value of the output=input -7 . if the decimal value of the binary input (w xyz) is < 7,t he decimal value of the binary output = input +9 . the output is 0 otherwise .

In mathematics and computer science, a set is a collection in which order does not matter and there are no duplicates. in this problem, we are going to to define a class which wil allow us to create an object to represent a set of integers. you will write a program set.java to define the class set. each instance of the class set will be an object representing a set of integers.

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?

You need a reliable network for about twenty-five computers that will be distributed across a large building. it is important that the network be relatively cheap. which topology should you use?
