Long Answer Type Questions 

Question. When using a search engine to search, then would you use quotation marks around search terms? 
Answer: - Quotation marks should be used around a phrase or search terms. Surrounding terms with quotation marks limit the search results to only those Web pages that contain the exact phrase, we have specified.
- Doing this ensures that, the concept will be searched for as a whole and not picked apart by the search engine or we can say, without the quotation marks, the results will include any page that contains the words we have used regardless of what order those words are in.
- e.g. typing death penalty without quotation marks could potentially retrieve all items that mention death, all items that mention penalty as well as the items about death penalty. This could lead to results that seem to have nothing to do with your topic. For best results, you should write “death penalty”.

Question. Transferring files through E-mail is restricted due to fill size. Justify.
Answer: - Over the Internet, a message will often pass through several mail transfer agents to reach the recipients. Each of these has to store the message before forwarding it on and many therefore, need to impose size limits.
- The result is that while large attachments may internally send within an organisation, they are unreliable when sending across Internet.
