You are asked to write a program that will display a letter that corresponds with a numeric rating system. The program should use a switch statement. The numeric rating is stored in a variable named rate and rate may equal 1, 2, 3, or 4. The corresponding letter is stored in a variable named grade and grade may be A, B, C, or D. Which is the test expression for this switch statement

What are procedures that keep a data base current

Consider a byte-addressable computer with 16mb of main memory, a cache capable of storing a total of 64kb of data and block size of 32 bytes. (a) how many bits in the memory address? (b) how many blocks are in the cache? (c) specify the format of the memory address, including names and sizes, when the cache is: 1. direct-mapped 2. 4-way set associative 3. fully associative

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
