(a) Juhi uses a computer to send e-mails to her sister in America :

1. To send mail to her sister, Juhi needs to first log in to her e-mail account and then follow these steps :
   Step 1 — Click on Compose button to compose a new mail message.
   Step 2 — In the Compose Message window, type the e-mail address of her sister in the To field.
   Step 3 — Fill in the subject of the message in the Subject field.
   Step 4 — Click on the Attach a file link below Subject box. Browse through the computer and select the photograph to be sent. Then click on Open.
   Step 5 — Write the message in the box designated for it.
   Step 6 — Click on Send button.

2. Juhi can send the following types of files through e-mail:

   1. Documents — This includes files in formats such as DOCX (Microsoft Word), PDF (Portable Document Format), XLSX (Microsoft Excel), PPTX (Microsoft PowerPoint), and TXT (plain text files).
   2. Images — Popular image formats like JPEG, PNG, GIF, and BMP can be attached to emails. These files can include digital photos, illustrations, or graphics.
   3. Audio files — Formats like MP3, WAV, and AAC can be sent as email attachments. These files can include music, sound effects, or voice recordings.
   4. Video files — Common video file formats such as MP4, AVI, MOV, and WMV can be attached to emails. These files can include recorded videos or video clips.
   5. Compressed files — Archives or compressed files, like ZIP or RAR, can be sent as email attachments. These files are used to combine multiple files into a single compressed file for easier sharing.
   6. Presentations — Presentation files, such as PPTX (PowerPoint) or Keynote files, can be sent via email.
   7. Spreadsheets — Spreadsheet files, like XLSX (Excel) or CSV (Comma-Separated Values), can be attached to emails.

(b) Juhi is using a search engine to research Indian freedom struggle history :

1. Two reasons why computer is taking longer to respond are :

   1. Slow internet connection — If Juhi has a slow internet connection, it can significantly affect the response time of the search engine.
   2. High server load — The search engine's servers may be experiencing a high volume of requests, leading to slower response times.

2. Two things Juhi can do to reduce the number of links are:

   1. Use specific keywords — Instead of using a broad term like 'Gandhi', Juhi can refine her search by including more specific keywords related to her research topic. For example, she can search for 'Mahatma Gandhi Indian freedom struggle' or 'Gandhi's role in Indian independence movement'. Adding relevant keywords will help narrow down the search results to more specific and relevant information.
   2. Utilize advanced search operators — Juhi can use operators like quotation marks (" ") to search for exact phrases or hyphen (-) to exclude specific words or terms. For example, she can search for "Mahatma Gandhi" -movie to exclude links related to movies about Gandhi.
