Computer Science

HTML stands for Hypertext Markup Language, which is the standard language used to create and design web pages. This is a well-known and established fact in computer science.

CD-ROM stands for Compact Disc Read-Only Memory, which means data on the disc can only be read and not written or erased.

IBM stands for International Business Machines, which is the correct full form of the acronym IBM.

The keys labeled F1 through F12 on a keyboard are known as function keys because they perform specific functions depending on the software or operating system in use.

In computer science, 'PB' commonly stands for 'Petabyte,' which is a unit of digital information storage equal to 1,024 terabytes. The other options are incorrect in this context.

Ctrl + Y is the standard keyboard shortcut for the 'Redo' action, which reverses the last undo operation. This is distinct from Ctrl + Z, which is used for 'Undo'.

The correct HTML tag to underline text is <u>. Since none of the given options (B, C, D) represent the <u> tag, the correct answer is 'None of these'.

The welcome screen in most operating systems displays the names of all user accounts available on the computer, allowing users to select their profile to log in. This matches option B, making it the correct answer.

A bit is the basic unit of digital information and represents a binary value of either 0 or 1. It is not equal to any decimal number like 0.125, 0.150, or 0.12, so the correct answer is 'None of these'.

Facebook was launched in 2004 by Mark Zuckerberg and his college roommates. This is a well-documented fact in the history of social media platforms.

HTML stands for Hypertext Markup Language, which is the standard language used to create and design web pages.

CD-ROM stands for Compact Disc Read-Only Memory, which means data can be read from the disc but not written or modified.

A gigabyte (GB) is larger than a megabyte (MB) and a kilobyte (KB), making it the largest unit among the options provided for measuring computer memory.

The Archive folder allows users to keep emails for future reference without leaving them in the inbox. It helps organize and manage emails efficiently while preserving important messages.

In emails, 'CC' stands for 'Carbon Copy,' which allows the sender to send a copy of the email to additional recipients beyond the primary recipient.

Email is generally considered the slowest response method for collecting data because respondents may take longer to reply compared to direct or real-time data collection tools. It depends on user availability and internet communication delays.

An email bounce typically occurs due to issues like a bad user account name, bad domain name, or the domain server being down. A stale file handle is a filesystem-related error and not a common reason for email bounces.

Email attachments can include various types of files such as documents, images, and videos. These are commonly sent to share information or media with recipients.

The 'Sent Items' folder stores emails after they have been successfully sent. The 'Outbox' holds emails waiting to be sent, 'Drafts' contains unfinished emails, and 'Spam' holds unwanted or junk emails.

The 'Bcc' (Blind Carbon Copy) field hides the identity of the recipients from other recipients, unlike 'To', 'From', or 'Cc' fields which are visible to all recipients.

Unsolicited bulk e-mail is commonly known as spam, which refers to unwanted or junk email sent in large quantities.

BCC stands for Blind Carbon Copy, which is used in emails to send a copy to recipients without revealing their addresses to others.

Unfinished emails that are saved without being sent are stored in the Drafts folder, allowing users to return and complete them later.

The Outbox folder temporarily stores emails that are waiting to be sent. Once sent, emails move to the Sent Items folder. Inbox stores received emails, and Archive is for storing older emails.

In Gmail, the 'Reply All' function sends your response to the original sender and all recipients listed in the To and Cc fields, ensuring everyone involved in the conversation receives your reply.
