A digital computer has a memory unit with 24 bits per word. Theinstruction set consists of 199 different operations. Allinstructions have an operation code part (opcode) and an addresspart (allowing for only one address). Each instruction is stored inone word of memory. [8 marks] How many bits are needed for theopcode? How many bits are left for the address part of theinstruction? What is the maximum allowable size for memory? What isthe largest signed binary number that can be accommodated in oneword of memory?
