Check Understanding Topic 1.1.1-1.1.4

Which of the following BEST defines an Operating System?

• A hardware component that runs applications

• Program that acts as and intermediary between

  a user of a computer and the computer hardware

• A program used to write application software

• A device driver used to control hardware

The earliest and most common OS. Each component of the OS is contained within the kernel. This is refer to:

• Layered Structure

• Monolithic Structure

• Microkernel Structure

• Distributed Structure

This is the highest layer in the layered OS. This layer deals with many user programs and applications that run in OS such as word processors, games, browser. It refers to:

• CPU Scheduling

• Hardware

• Process Management

• User Program

A group of computer (nodes) working together as a single system. These computers are connected via a network to share resources and handle tasks collectively. This refer to:

• Multiprocessor System

• Clustered System

• Network Structured

• Distributed Structured

The kernel has:

• Restricted access to hardware

• No interaction with memory

• Unrestricted access to all system resources

• Access only to application programs

Which of the following is NOT a basic function of an Operating System?

• Resource Allocation

• Control Program

• Compiling source code

• Ease of Use

In a monolithic structure operating system:

• Components are isolated in separate layers

• All OS components are embedded into the kernel

• Only user-level programs manage processes

• It is slower than microkernel structure

Which type of operating system structure provides modularity by grouping components into layers?

• Monolithic Structure

• Layered Structure

• Networked Structure

• Distributed Structure

In a layered operating system structure, each layer:

• Can communicate with any other layer

• Only communicates with its nearest upper and lower layers

• Works independently without communication

• Has direct hardware access

The main difference between a networked and a distributed OS is:

• Distributed OS controls multiple computers as one system

• Networked OS is faster than distributed OS

• Networked OS requires no communication between nodes

• Distributed OS has no access to hardware
