### Understanding Computer Specifications: Address Bus, Databus, Memory Length, and AC **Question:** If a computer is specified as a 128-bit processor and can execute up to 64 instructions. What will be the size of the Address bus, Databus, Memory Length, AC? **Explanation:** This question involves several key concepts in computer architecture: 1. **Processor Bit Size**: - The bit size of a processor (in this case, 128-bit) determines the width of the data it can process at once. A 128-bit processor can handle 128 bits of data simultaneously. 2. **Address Bus Size**: - The address bus is used to specify the location of data in the memory. Its size determines the maximum amount of addressable memory. The size of the address bus is typically determined by the architecture of the processor. 3. **Databus Size**: - The databus width is directly related to the processor's bit size. Therefore, a 128-bit processor would typically have a databus width of 128 bits. 4. **Memory Length**: - The memory length refers to the amount of memory that can be directly addressed by the processor. This is influenced by the size of the address bus. 5. **AC (Accumulation Register/Accumulator)**: - The accumulator is a register in the CPU that stores intermediate results of arithmetic and logic operations. Its size usually matches the datapath size of the processor, so in this case, it would likely be 128 bits. **Calculations to Determine Each Component:** - **Address Bus**: - Assuming the processor follows binary addressing, the address bus width \( A \) can be calculated by solving \( 2^A = \text{total addressable locations} \). However, the prompt does not specify the maximum memory, so we cannot determine this directly from the given information alone. - **Databus**: - Since it is a 128-bit processor, the databus size is 128 bits. - **Memory Length**: - The total addressable memory is determined by the size of the address bus. For example, if the address bus is 32 bits, the addressable memory would be \( 2^{32} \) addresses. The exact size cannot be determined from the given information. - **AC**: - The size of the accumulation register aligns
