Data Processing Questions and Answers

When performing computer recovery operations after a system crash, the startup disk is used to recover the system disk from an image file.

A startup disk typically contains essential system files and tools that are required to boot the computer and initiate recovery procedures. One common approach to recovery after a system crash is to use an image of the system disk taken at a stable and functional state. This image is often referred to as a "system image" or "backup image." By using the startup disk and this image, you can restore the entire system to a previous state, which can include the operating system, applications, and data. This process helps in recovering from crashes and issues that render the system inoperable.

Computer malware is detected by antivirus software. Antivirus software is designed to identify, prevent, and remove various types of malicious software, commonly referred to as malware. This includes viruses, worms, trojans, spyware, adware, and other malicious programs that can harm or compromise a computer system. Antivirus software scans files, programs, and incoming data for patterns and behaviors associated with known malware, and it takes actions to quarantine or remove the detected threats. The other options mentioned—adware, antiglare, and logic bomb—are not directly related to detecting malware. Adware is a type of potentially unwanted software, antiglare refers to a screen feature, and a logic bomb is a type of malicious code that triggers when specific conditions are met.

To send an e-mail, the user typically clicks on the "New" part of the email application interface. This option allows the user to compose a new email message and enter the recipient's email address, subject, and content before sending it. The "New" button or option is used to initiate the process of creating a new email to be sent.

New messages that are received are typically saved in the inbox of an email application interface. The inbox is where incoming emails are displayed, allowing the user to see and manage new messages that have been received. The other options provided—New, sent items, and drafts—refer to different folders or sections within an email application, each serving a specific purpose:

New: This might refer to a "New Message" button or option, allowing you to compose and send new emails.
Sent Items: This folder contains copies of emails you have sent.
Drafts: This folder holds emails that you have started composing but have not yet sent.

One application of ICT (Information and Communication Technology) in medicine is computerized axial tomography (CAT or CT scan). Computerized axial tomography is a medical imaging technique that uses X-rays and computer processing to create detailed cross-sectional images of the body's internal structures. It is used for diagnosing and monitoring various medical conditions by providing detailed images of organs, tissues, and bones.

The volume of data that can be sent from one point to another in a given time period is called bandwidth. Bandwidth refers to the capacity of a communication channel to transmit data, typically measured in bits per second (bps) or its multiples like kilobits per second (Kbps), megabits per second (Mbps), and so on. It represents how much data can be transmitted over a network connection within a specific time frame.

Baud is a unit of data signaling rate, or the number of times per second that a signal changes state.
Byte is a unit of digital information, equal to 8 bits.
Broadband is a high-speed data transmission medium that can carry multiple signals simultaneously.

The advantages of parallel database include the following except huge resources.

Advantages of parallel databases typically include:

Greater Flexibility: Parallel databases can distribute and process data across multiple nodes, providing flexibility in handling various types of queries and workloads.

High Availability: Parallel databases can offer improved fault tolerance and availability through redundancy and distribution of data.

High Performance: Parallel processing allows for faster query execution and data processing, especially for complex analytical queries.

However, "huge resources" is not typically considered an advantage of parallel databases. While parallel databases can efficiently utilize resources across multiple nodes, the emphasis is on utilizing resources effectively rather than simply having a large quantity of resources.

The ruler feature in MS Word that is used to indent the second and subsequent lines of a paragraph is hanging indent. A hanging indent is when the first line of a paragraph starts at the left margin, but the following lines are indented, creating a visually staggered appearance. This is often used in bibliographies, reference lists, and other situations where the first line needs to be flush with the left margin, while subsequent lines are indented.

To create a hanging indent in MS Word, you can follow these steps:

Click on the Paragraph tab.
In the Indentation section, click on the Special drop-down menu and select Hanging.
Enter the amount of indent that you want for the second and subsequent lines in the By box.
Click on the OK button.
The second and subsequent lines of the paragraph will now be indented.

The feature that is not found in the toolbox of CorelDraw application is the marque tool. While CorelDraw does offer tools for creating and manipulating shapes like ellipses, rectangles, and text, it does not typically include a specific "marque tool."

Analogue computer represents data as variable and continuous values.

Analogue computers use physical quantities, such as voltage, current, or resistance, to represent data. This means that they can represent data that is continuously varying, such as the position of a moving object or the temperature of a substance.

Digital computers, on the other hand, represent data as discrete values. This means that they can only represent data that is in a finite number of states, such as the numbers 0 and 1.

Mainframe computers and microcomputers are both digital computers.
