Explanation:
1)A) Equal sign is not a punctuation mark.
2)Search engines work by crawling hundreds of billions of pages using their own web crawlers. These web crawlers are commonly referred to as search engine bots or spiders. A search engine navigates the web by downloading web pages and following links on these pages to discover new pages that have been made available.
3)Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.

Q-2) What is a search engine? how does it work?
What is a search engine?
Search engines allow users to search the internet for content using keywords. Although the market is dominated by a few, there are many search engines that people can use. When a user enters a query into a search engine, a search engine results page (SERP) is returned, ranking the found pages in order of their relevance. How this ranking is done differs across search engines.
Search engines often change their algorithms (the programs that rank the results) to improve user experience. They aim to understand how users search and give them the best answer to their query. This means giving priority to the highest quality and most relevant pages.
How do search engines work?
There are three key steps to how most search engines work:
Crawling - search engines use programs, called spiders, bots or crawlers, to scour the internet. They may do this every few days, so it is possible for content to be out-of-date until they crawl your website again.
Indexing - the search engine will try to understand and categorise the content on a web page through 'keywords'. Following SEO best practice will help the search engine understand your content so you can rank for the right search queries.
Ranking - search results are ranked based on a number of factors. These may include keyword density, speed and links. The search engine's aim is to provide the user with the most relevant result.
Although most search engines will provide tips on how to improve your page ranking, the exact algorithms used are well guarded and change frequently to avoid misuse. But by following search engine optimisation (SEO) best practice you can ensure that:
Search engines can easily crawl your website. You can also prompt them to crawl new content.
Your content is indexed for the right keywords so it can appear for relevant searches.
Your content can rank highly on the SERP.
Q-3) What is meant by cloud computing?
Cloud computing is the delivery of different services through the Internet. These resources include tools and applications like data storage, servers, databases, networking, and software. ... As long as an electronic device has access to the web, it has access to the data and the software programs to run it.
