Which of the following is NOT one of the types of buses?a)Control busb...
Bus: In computer architecture, a bus (related to the Latin “omnibus”, meaning “for all”) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
The types of buses are:
Address Bus:
  • It is a unidirectional Bus, which is responsible for only one-way communication.
Data Bus:
  • It is a bi-directional bus.
  • Data and Instructions pass through this bus to reach the microprocessor.
  • This is responsible for the exchange of information between the main memory and microprocessor.
Control Bus:
  • The control bus carries control signals partly unidirectional and partly bidirectional
  • This tells whether read or write, which operation should be performed that is in which direction the data should flow.
So Utility Bus is not a type of bus used in computer architecture, hence option 4 is the correct answer.

Types of Buses in a Computer System

The buses in a computer system facilitate the communication between different components such as the CPU, memory, and peripherals. They are essential for the transfer of data, addresses, and control signals within the system.

Control Bus
- The control bus is responsible for transmitting control signals between the CPU and other components.
- These signals include commands to read from or write to memory, signals to initiate input/output operations, and interrupt signals.

Data Bus
- The data bus is used for transferring data between the CPU, memory, and I/O devices.
- It carries the actual data being processed by the system.

Address Bus
- The address bus is used to specify a physical address in memory or an I/O device.
- It allows the CPU to communicate with specific locations in memory or peripherals.

Utility Bus
- The term "utility bus" is not commonly used in the context of computer architecture or buses.
- There is no standard definition or functionality associated with a utility bus in computer systems.

In conclusion, the control bus, data bus, and address bus are fundamental types of buses in a computer system, whereas the utility bus is not a recognized type of bus in the typical architecture of computers.

Similar Computer Science Engineering (CSE) Doubts

A processor uses 2-level page tables for virtual to physical address translation. Page tables for both levels are stored in the main memory. Virtual and physical addresses are both 32 bits wide. The memory is byte addressable. For virtual to physical address translation, the 10 most significant bits of the virtual address are used as index into the first level page table while the next 10 bits are used as index into the second level page table. The 12 least significant bits of the virtual address are used as offset within the page. Assume that the page table entries in both levels of page tables are 4 bytes wide. Further, the processor has a translation look-aside buffer (TLB), with a hit rate of 96%. The TLB caches recently used virtual page numbers and the corresponding physical page numbers. The processor also has a physically addressed cache with a hit rate of 90%. Main memory access time is 10 ns, cache access time is 1 ns, and TLB access time is also 1 ns. Suppose a process has only the following pages in its virtual address space: two contiguous code pages starting at virtual address 0x00000000, two contiguous data pages starting at virtual address 000400000, and a stack page starting at virtual address 0FFFFF000. The amount of memory required for storing the page tables of this process is
