Worksheet time: 21mins
What is Operating System?
interface between the user and the hardware
an ordinary centralized OS but runs on several independent CPUs
to provide an environment in which user can execute program in a convenient & eficient manner
execute the one process at the time
What is Program? Choose two (2)
Passive entity
Original code and binary code
Active Entity
can create many processes when run multiple times
What is Process? Choose two (2)
Passive entity
Original code and binary code
Active Entity
can create many processes when run program multiple times
Choose the correct statement of the purpose of OS
Device Controlling: Protects the data stored on the computer from illegal use, modification or deletion
Loading & Execution: Its primary task feed the programs in the memory (such as RAM) for execution the all instruction without more delay.
Disk Management:
Protects the data stored on the computer from illegal use, modification or deletion
Memory Management:
Manages the stored files and folders in a proper way
Which is not an OS environment?
Medium to communicate to computer (binary language)
Manage and coordinate computer resources (software & hardware)
System software that runs on computer (any electronic devices)
A process of starting a computer. It can be initiated by hardware such as a button press, or by a software command
Statement below are about Single Processor System. Which one (1) is NOT TRUE?
A computer system that has a single CPU
These systems are referred as tightly coupled systems
Other processes must wait until the processor becomes free
Only one process can run or execute at a time
All processing tasks share a single CPU
Statement below are about Multi-Processor System. Which one (1) is NOT TRUE?
A computer system that has a single CPU
These systems are referred as tightly coupled systems
Refers to the use of two or more CPU within a single computer system
These multiple CPU are in a close communication sharing the computer bus, memory and other peripheral devices
Statement below are about Clustered System. Which one (1) is NOT TRUE?
using asymmetric clustering and summetric mode
Share storage and closely linked via LAN networking
uses multiple CPUs to complete a task
a group of people and other part of storage system
System contains only one processing than it is called :
Single Processor System
Multi-Processor System
System contains two or more than two processors for processing than it is called :
Single Processor System
Multi-Processor System
Throughput is greater other processor systems
Single Processor System
Multi-Processor System
Throughput is less than other processor systems. because each and every task is performed by the same processor
Single Processor System
Multi-Processor System
More reliable because failure of one processor does not halt the entire system but only speed will be slow down
Single Processor System
Multi-Processor System
Cost more because each processor requires separate resources i.e mass storage, peripherals, power supplies etc
Single Processor System
Multi-Processor System
Blade servers is an examples of:
Single Processor System
Multi-Processor System

Which one is NOT an OS components
Secondary Storage Management
Process Management
Network Management
User Management
The core software components of an operating system are collectively known as the (a)
There are two (2) types of kernel in OS structures. Monolithic Kernel and (a)
In Monolithic Operating System, each component will directly communicate.
