Email (Electronic Mail) is a fundamental digital communication tool that allows users to send and receive messages over the internet. For the HSSC CET Computer Knowledge section, you must understand the practical aspects of managing an email account — creating messages, handling attachments, organizing folders, and configuring settings like signatures.
Key ideas
- Email Address Format: Every email address follows the pattern [email protected]. The @ symbol separates the user's name from the mail server domain (e.g., [email protected]).
- SMTP, POP3, and IMAP: These are email protocols. SMTP (Simple Mail Transfer Protocol) sends emails. POP3 (Post Office Protocol) downloads emails to your device and usually deletes them from the server. IMAP (Internet Message Access Protocol) keeps emails on the server, allowing access from multiple devices.
- Inbox: The default folder where all incoming emails are received. It is the primary location for reading new messages.
- CC (Carbon Copy) and BCC (Blind Carbon Copy): CC sends a copy of the email to additional recipients, and all recipients can see who received the CC. BCC also sends copies, but recipients cannot see BCC addresses — used for privacy.
- Attachment: A file (document, image, PDF) sent along with an email. Most email services limit attachment size to 25 MB per email.
Watch out for
- Confusing CC with BCC → Remember: CC recipients are visible to everyone; BCC recipients are hidden. For confidential mass mailing, always use BCC.
- Thinking "Reply All" is safe → Reply All sends your response to every person in the original email chain. Use it only when everyone needs to see your reply; otherwise, use "Reply."
- Ignoring the Subject line → Leaving the subject blank or writing vague subjects like "Hi" is unprofessional and may trigger spam filters. Always write a clear, relevant subject.
Quick reference
- Email format: [email protected] — @ symbol is mandatory.
- SMTP sends, IMAP/POP3 receives — never confuse protocols.
- CC = visible copy, BCC = hidden copy — use BCC for privacy.
- Maximum attachment size — typically 25 MB (Gmail, Outlook).
- Signature — auto-added text block with sender's details at email end.
