Question 1

Expansion cards plug into electrical connectors on the motherboard called ____.

Accepted Answer

Expansion cards plug into slots on the motherboard, not ports, cables, or buses.

Question 2

A network with a file server is called a client/server network.

Accepted Answer

A client/server network refers to a network architecture where multiple clients or end-user devices connect to a central server, which manages and provides access to shared resources and services like files, printers, applications, or databases. The server stores and manages the data while clients request and use the data.

Question 3

(a)  (b)  (c)  (d) In the above figure, which screen shows software used for numerical analysis?

Accepted Answer

Screen B shows a software used for numerical analysis as it displays the plot of a function and has options for selecting the type of plot and displaying numerical results. The other screens do not show any numerical analysis software or tools.

Question 4

The seamless nature of OLE among some applications is referred to as ____.

Accepted Answer

The seamless nature of OLE among applications is referred to as integration. OLE (Object Linking and Embedding) allows objects from one application to be linked or embedded into another, resulting in a seamless integration of multiple applications.

Question 5

A device driver is a computer program that makes communication possible between your computer and one of its peripherals.

Accepted Answer

A device driver is a program that allows the operating system and a device to communicate with each other. It acts like a translator, converting the commands and instructions of the operating system into a language that the device can understand and process. Without device drivers, the operating system would not be able to recognize and use the peripherals connected to the computer.

Question 6

A tape drive is a type of magnetic storage device.

Accepted Answer

A tape drive is a type of magnetic storage device that reads and writes data onto magnetic tape.

Question 7

The network shown in the figure above is a ____ network.

Accepted Answer

The network shown in the figure is a client/server network because the central device, TBX9074, is serving as the server and the other devices connected to it (labeled "PC", "Printer", "Scanner", and "NAS") are acting as clients.

Question 8

The practice of sending e-mails to customers or potential customers of a legitimate Web site asking them to click a link in the e-mail is called ____.

Accepted Answer

This practice is known as phishing, where the perpetrator attempts to obtain sensitive information, such as login credentials or credit card numbers, by posing as a trustworthy entity in an electronic communication. Spoofing refers to falsifying the sender or source of an electronic communication, pharming involves redirecting website traffic to a fake site, and swishing is not a term commonly used in the context of online security or communication.

Question 9

CD-ROMs are rewritable.

Accepted Answer

CD-ROMs are not rewritable. They are read-only memory and can only be written to once.

Question 10

Polycarbonate discs coated with a reflective metal on which data is recorded using laser technology as a trail of tiny pits or dark spots in the surface of the disc are ____ storage devices.

Accepted Answer

The description matches that of optical storage devices, specifically CDs or DVDs. Magnetic storage devices use magnetic fields to record data, flash storage uses memory chips, and USB refers to a type of connection/interface for devices rather than a storage technology.

Question 11

Antivirus software protects against which of the following types of malware?

Accepted Answer

Antivirus software protects against all types of malware including viruses, Trojan horses, and worms.

Question 12

CMOS is often referred to as ____ memory.

Accepted Answer

CMOS memory is considered semipermanent because it retains information as long as it receives power, typically from a small battery, but loses data when the power is lost.

Question 13

A parallel port is relatively slow, as it transmits data one bit at a time.

Accepted Answer

A parallel port transmits multiple bits simultaneously, making it faster than a serial port, which transmits data one bit at a time.

Question 14

The communication path between a microprocessor, RAM, and peripherals is called the data bus.

Accepted Answer

The data bus is the communication path that connects the microprocessor, RAM, and peripherals together. It allows data to be transferred between these components in order to perform various operations in a computer system.

Question 15

An interface card could be plugged into an expansion slot on the main board of a computer.

Accepted Answer

An interface card, such as a network card or sound card, can be plugged into an expansion slot on the motherboard of a computer. The expansion slot provides a way to add new features and functionality to the computer without having to replace the entire motherboard.

Question 16

Each of the components connected by wires in the above figure is called a ____.

Accepted Answer

Each component connected by wires is referred to as a node in a network. A client is a device or application that accesses a service provided by a server, a workstation is a computer used for work purposes, and a server is a device or program that provides functionality or services to other devices or programs on a network. Therefore, option B, node, is the best choice.

Question 17

Each of the items labeled workstation in the above figure must have a network intercommunication card installed.

Accepted Answer

Since these workstations need to communicate with each other and access the network, they must have network intercommunication cards installed.

Question 18

____ allocate system resources, manage storage space, maintain security, detect equipment failure, and control basic input and output.

Accepted Answer

Operating systems are designed to allocate system resources, manage storage space, maintain security, detect equipment failure, and control basic input and output. Utilities may assist with some of these tasks, but they typically refer to specific applications or programs that perform specific functions, while operating systems provide the foundation for a computer's overall functionality. Programming languages and database management software are not designed to perform these tasks.

Question 19

Protocols in data communication establish the countries with which data can be exchanged.

Accepted Answer

Protocols in data communication establish the rules and procedures for transmitting data between devices within the same country or across international borders, but they do not determine the specific countries with which data can be exchanged. That is typically determined by laws, regulations, and trade agreements between countries.

Question 20

A PC card slot could contain a hard disk drive.

Accepted Answer

Some laptops have PC card slots which can be used to insert a hard disk drive. However, this is becoming less common with the popularity of other forms of external storage such as USB drives and cloud storage.
