Understanding Computer Architecture and Management

What is the primary purpose of pipelining in RISC processors?

• To increase the clock speed of the processor

• To execute multiple instructions simultaneously

• To reduce the power consumption of the processor

• To increase the size of the instruction set

Which of the following architectures is characterized by a single instruction stream and multiple data streams?

• SISD

• SIMD

• MISD

• MIMD

What is a key characteristic of massively parallel computers?

• They use a single processor to perform all computations

• They have a large number of processors working simultaneously

• They rely on quantum computing principles

• They are limited to executing sequential tasks

In memory management, what is the main difference between paging and segmentation?

• Paging divides memory into variable-sized blocks, while segmentation divides it into fixed-sized blocks

• Paging divides memory into fixed-sized blocks, while segmentation divides it into variable-sized blocks

• Both paging and segmentation divide memory into fixed-sized blocks

• Both paging and segmentation divide memory into variable-sized blocks

What is virtual memory primarily used for?

• To increase the physical memory of a computer

• To allow a computer to run multiple operating systems simultaneously

• To extend the apparent memory capacity by using disk space

• To improve the speed of data retrieval from the hard drive

Which of the following is a method for replacing pages in virtual memory?

• First-In-First-Out (FIFO)

• Last-In-First-Out (LIFO)

• Least recently used

• All of the above

What is disk thrashing?

• A method to increase disk speed

• A condition where excessive paging operations reduce system performance

• A technique to optimize disk storage

• A type of disk error

What is a virtual machine?

• A physical computer that runs multiple operating systems

• A software emulation of a physical computer

• A type of cloud storage

• A hardware device for data encryption

Which of the following is a benefit of using virtual machines?

• They require less physical hardware

• They eliminate the need for an operating system

• They increase the speed of the processor

• They provide unlimited storage capacity

What is a limitation of virtual machines?

• They cannot run multiple applications

• They have limited compatibility with software

• They can be resource-intensive and slow down the host system

• They do not support network connectivity
