Question

State if the given statements are true or false by reporting your answers (T for ``true’’ and F for ``false’’) in the last column of the following table.

(i)	1000 bits equal one byte.
(ii)	Batch processing allows the creators of computing jobs to interact with the jobs during their completion.
(iii)	Multiprogramming assigns the same time interval to all computing jobs.
(iv)	1000 bytes equal one kilobyte.
(v)	Multiprogramming is used only in multi-user settings.
(vi)	1 terabyte equals more bits than 1 gigabyte.
(vii)	Batch processing is a kind of multitasking.
(viii)	Scaling in the context of operating systems is same as speeding up or slowing down the processes aimed at completion of computing jobs based on the deadlines given by the creators of the jobs.
(ix)	Load balancing in the context of operating systems means splitting the computer programs written in  high-level programming languages into smaller programs, to make sure that all processors are assigned equal number of lines of code written in the high-level programming languages.
(x)	1 megabyte equals 8 terabytes.
(xi)	There are multiple criteria for classifying computer networks.
(xii)	The only way to create a larger computer network from bus networks is to connected them with a bridge.
(xiii)	File manager is a part of user interface.
(xiv)	Booting is the process of transferring the operating system from the main memory to the mass storage.
(xv)	1 exabyte equals 250 kilobytes.
(xvi)	Device drivers are a part of user interface.
(xvii)	Star networks are same as networks of computers used to process data about stars in the sky.
(xviii)	1 petabyte equals 253 bits.
(xix)	Auditing software in the context of operating systems is a software that creates a software during an attack on a computer/computers, to defend the computer/computers.
(xx)	A dispatcher in the context of operating systems chooses the activities to consider for execution.

Answer 1

(i) False.

8 bits is equal to 1 byte.

(ii) False.

In Batch processing jobs run without end user interaction

(iii) False

Multiprogramming assigns a time interval to only one of the jobs waiting to be executed.

(iv) False.

1024 bytes equal one kilobyte.

(v) False

Multiprogramming can be used for single user system as well.

(vi) True

1 terabyte = 2^43 bits, while 1 gigabyte = 2^33 bits. so 1 terabyte has more bits.

(vii) False

In multitasking we have a time based context switching while in batch processing the jobs are executed in first come first serve basis.

(viii) False

Scalability is the property of a system to handle a growing amount of work by adding resources to the system.

(ix) False

Load balancing is defined as the methodical and efficient distribution of network or application traffic across multiple servers in a server farm.

(x) False

1 megabyte equals 2^(-20) terabytes.

(xi) True

There are multiple criteria for classifying computer networks. such as Geographical spread, Topology, Ownership

(xii) False

(xiii) True

A file manager is a computer program that provides a user interface to manage files and folders.

(xiv) False

Booting is the process of transferring the operating system from the mass storage to the main memory.

(xv) False

1 exabyte is approximately equal to1,000 Petabytes

(xvi) False

The device driver acts as an interface between computer components.

(xvii) False.

In a star network, every host is connected to a central hub. The star network is one of the most common computer network topologies. The hub and hosts, and the transmission lines between them, form a graph with the topology of a star.

(xviii) True.

(xix) False

Audit software automates the process of preparing and executing audits by helping organizations analyze data, assess risks, track issues, report results and manage paperwork.

(xx) False.

The job of selecting a process among various processes is done by the scheduler.
