Answer : 1. "clip board"
Explanation :
When you use the copy command (Ctrl+C on Windows) to copy a file or text, the data is temporarily saved in an area of the computer's memory called the clipboard. The clipboard is a temporary storage location that holds the data you have copied or cut until you paste it elsewhere (using Ctrl+V on Windows). The clipboard allows you to move or duplicate data within or between applications.

Answer : 3. "Yahoo"
Explanation :
The search engine performs the following tasks-
1. Web crawling: Search engines search all web pages on the web using a crawler. A crawler is a program that finds new web pages by following links on the web.
2. Indexing: Once the crawler finds all the web pages, the search engine indexes them in a database. The index contains information for each web page, such as title, URL, and content.
3. Searching: When a user types a search query, the search engine searches all the web pages in the index that may be related to the query.
