The correct answer is Kernel

Key PointsA search engine typically consists of three primary components:

• Search Algorithm: This is the set of rules and calculations that a search engine uses to determine the relevancy of web pages in relation to specific search queries.
• Search Index: This is a massive database where all the information the search engine has gathered is stored. When a search is performed, the engine isn't searching the web in real-time, but its own index of the web.
• Crawler (also known as a Spider or Bot): This is a program that automatically navigates the internet by following links from page to page. It "crawls" around the web collecting information to be indexed.

On the other hand, the Kernel is the core part of a computer's operating system with complete control over everything in the system. It's crucial for the OS function but is not specifically related or essential to the function of a search engine. Therefore, the Kernel is NOT a main part of a search engine.

Additional Information

• User Interface: The search engine user interface often gets overlooked, but it's also an important component. This includes features such as the search box where you input your queries, the search results page, and the presentation of the information (like displaying a snippet of website content, image, or video previews). How easy it is for a user to interact with, and get useful information from a search engine, often comes down to the design of this interface.

The correct answer is Dot per inch.

Key Points

• The output quality of a printer is measured by Dot per inch.
• DPI represents a number of ink dots the printer can place in an area of one square inch**.**
• It refers to the physical dot density of an image when it is reproduced as a real physical entity, for example, printed onto paper**.**
• In printing, dots per inch (DPI) is the usual measure of printed image quality on the paper. The average personal computer printer today provides 300 dpi or 600 dpi.
• The lesser the DPI the less sharp the image and vice versa.

Additional Information

• DPI stands for Dots Per Inch which technically means printer dots per inch. Today it is a term often misused, usually to mean PPI, which stands for Pixels Per Inch.
• So when someone says they want a photo that is 300 dpi they really mean that they want 300 PPI.
• Each printer has its own capabilities of printing. With standard printers,
• dot matrix is commonly the lowest quality printer**,**
• inkjet printers are commonly average quality**, and**
• laser printers are commonly the best quality.
