An email address consists of two parts, the username (or name) and the domain name, separated by the "@" symbol. The domain name typically includes a top-level domain (TLD) such as .com, .org, .net, .edu, .gov, or others.

Option (a) is incorrect because it contains two "@" symbols, which is not a valid format for an email address.

Option (c) is incorrect because it is a website URL, not an email address.

Option (d) is also incorrect because it is not a valid format for an email address. A valid domain name should follow certain rules, such as not containing spaces and having a TLD.

Therefore, the correct answer is (b) name@website.info.

The correct answer is (b) Cyber Attack.

A Cyber Attack is an attempt to harm, damage, or cause a threat to a system or network using technology, such as a computer or the internet. Cyber attacks can take many forms, including malware, phishing, ransomware, denial-of-service (DoS) attacks, and many others. The goal of a cyber attack is often to steal data, disrupt services, or gain unauthorized access to systems or networks.

Option (a) Cyber-crime refers to any criminal activity that involves the use of a computer or network, including cyber attacks but also other forms of crime such as identity theft, fraud, and online harassment.

Option (c) System hijacking refers to the act of taking control of a computer system without the owner's consent or knowledge, often for malicious purposes.

Option (d) Digital crime is a broad term that encompasses all criminal activities that involve digital technology, including cyber attacks, cyber crime, and other forms of illegal activities carried out using computers or the internet.

The correct answer is (b) Cookies.

Cookies are small text files that websites put on your computer or mobile device to store information about you and your preferences. Cookies are used to remember your login information, your shopping cart contents, your language preferences, and other settings so that you don't have to enter them every time you visit a website.

Option (a) URL stands for Uniform Resource Locator, which is the address of a website or web page on the internet.

Option (c) Address is a generic term that can refer to various things, including a physical address, an email address, or a web address.

Option (d) Home Page is the main page of a website that typically serves as the starting point for navigation.

Therefore, the correct answer is (b) Cookies.

The correct answer is (b) From Insert menu choose New Slide.

To insert a new slide in the current presentation in Microsoft PowerPoint, you can use the "New Slide" command from the "Insert" menu. This will add a new slide to the presentation based on the default slide layout.

Option (a) is incorrect because the "Page Setup" command from the "Design" menu is used to adjust the page size, orientation, and other settings for the current slide.

Option (c) is also incorrect because the "Layout" command from the "Home" menu is used to change the layout of the current slide, rather than add a new slide.

Option (d) is incorrect because the "Reset" command from the "Home" menu is used to undo recent changes to the current slide, rather than add a new slide.

Therefore, the correct answer is (b) From Insert menu choose New Slide.

The correct answer is (c) Functions.

In a computer spreadsheet, SUM, AVERAGE, MIN, and MAX are examples of functions. Functions are built-in formulas that perform specific calculations or operations in a spreadsheet. They are designed to simplify common mathematical or statistical tasks, and they can be used to quickly calculate totals, averages, minimums, maximums, and other values based on the data in the spreadsheet.

Option (a) Calculations and option (b) Formulas are related to functions, but they are not the same thing. Calculations refer to any mathematical or statistical operation performed on data in a spreadsheet, while formulas are combinations of values, operators, and functions that are used to calculate a result.

Option (d) Relative addressing refers to a method of referring to cells in a spreadsheet based on their position relative to the current cell. It is used in formulas and functions to make them easier to copy and reuse in different parts of the spreadsheet.

Therefore, the correct answer is (c) Functions.
