Question 1

Networking was not always an integral part of operating systems.

Accepted Answer

In the early days of operating systems, networking was not built-in and had to be added on through additional software and hardware.

Question 2

Until the mid-1970s, all computers were classified by price alone.

Accepted Answer

Computers were classified by various factors including performance, size, and intended use, not just by price.

Question 3

The Memory Manager, the Interface Manager, the User Manager, and the File Manager are the basis of all operating systems.

Accepted Answer

While these components are important in many operating systems, they are not the basis of all operating systems. Different types of operating systems may have different components or place emphasis on different aspects of managing the computer's resources.

Question 4

An operating system is a special type of hardware.

Accepted Answer

An operating system is not hardware, it is software that manages and controls the hardware of a computer system.

Question 5

The Device Manager monitors every device, channel, and control unit.

Accepted Answer

The Device Manager is designed to monitor every device, channel, and control unit in order to ensure smooth functioning and detect any issues or anomalies that may arise. This allows for efficient maintenance and troubleshooting, and helps to prevent disruptions or downtime.

Question 6

The central processing unit (CPU) is the brains of the computer with the circuitry to control the interpretation and execution of instructions.

Accepted Answer

The statement is true. The CPU is responsible for processing and executing instructions in a computer system.

Question 7

Real-time systems are used in time-critical environments where reliability is key and data must be processed within a strict time limit.

Accepted Answer

Real-time systems are designed to process data and respond within a specific timeframe, making them ideal for environments where timing and reliability are critical. Examples of such systems include air traffic control systems, medical equipment, and industrial control systems.

Question 8

The operating system manages each and every piece of hardware and software.

Accepted Answer

The operating system is responsible for managing all hardware and software resources of a computer system. It controls the execution of programs and manages tasks such as memory allocation, input/output, and network communication.

Question 9

Operating systems with networking capability have a fifth essential manager called the Network Manager that provides a convenient way for users to share resources while controlling users' access to them.

Accepted Answer

This statement is true. The Network Manager is responsible for managing network connections and facilitating resource sharing among users while controlling their access to network resources.

Question 10

The File Manager is responsible for data files but not program files.

Accepted Answer

The File Manager is responsible for managing both data files and program files, handling their storage, retrieval, and organization on a computer system.

Question 11

Onboard systems are computers placed inside other products to add features and capabilities.

Accepted Answer

The correct term for computers placed inside other products to add features and capabilities is "embedded systems," not "onboard systems."

Question 12

The first bug was a moth trapped in a Harvard computer.

Accepted Answer

This is a widely-known fact in computer history. The moth was found trapped in the Harvard Mark II computer relays in 1947, and the term "debugging" was coined to refer to the process of fixing computer issues.

Question 13

Since the mid-1970s rapid advances in computer technology have blurred the distinguishing characteristics of early machines.

Accepted Answer

The statement accurately reflects the evolution of computer technology over the past few decades. Early machines were distinct in terms of their size, computing power, and other features, but the widespread availability of microprocessors and other innovations have led to convergence across different types of devices. Today, computers come in many sizes and forms, from handheld devices to massive data centers, and the differences between them are often a matter of degree rather than kind.

Question 14

The high-level portion of the Process Manager is called the Process Scheduler.

Accepted Answer

The answer of The high-level portion of the Process Manager...

Question 15

The Intel 4004 chip in 1971 had 2,300 transistors while the Pentium II chip twenty years later had 7.5 million, and the Pentium 4 Extreme Edition processor introduced in 2004 had 178 trillion transistors.

Accepted Answer

The statement is false. The Pentium 4 Extreme Edition processor introduced in 2004 had approximately 178 million transistors, not trillion.

Question 16

When the Processor Manager receives a command, it determines whether the program must be retrieved from storage or is already in memory, and then notifies the appropriate manager.

Accepted Answer

The Processor Manager is responsible for managing the execution of processes, which includes determining if a program is already in memory or needs to be loaded from storage, and coordinating with other managers like the Memory Manager.

Question 17

Card systems date from the earliest computers, which relied on punched cards or tape for input when a job was entered by assembling the cards into a deck and running the entire deck of cards through a card reader as a group.

Accepted Answer

The answer of Card systems date from the earliest computers,...

Question 18

The minicomputer of the 1970s was smaller than the microcomputer.

Accepted Answer

The minicomputer of the 1970s was larger than the microcomputer. Microcomputers were first introduced in the late 1970s and were smaller and less expensive than their minicomputer predecessors.

Question 19

The supercomputer was developed primarily for government applications needing massive and fast number-crunching ability to carry out military operations and weather forecasting.

Accepted Answer

The statement accurately describes the primary purpose of early supercomputers.

Question 20

The Memory Manager is in charge of indirect memory, also known as ROM.

Accepted Answer

The Memory Manager is in charge of the direct memory, also known as RAM, not indirect memory (ROM).
