Internet & E-mail
Web browsing and searching, download/upload, managing e-mail accounts, Reply/Forward, mail protocols and e-Banking — SSC CGL Tier-2 Computer module.
Seven concepts. Official SSC CGL Tier-2 Computer Proficiency names Working with Internet and e-mails as its own module: browsing and searching, downloading and uploading, managing an e-mail account, and e-Banking. Each concept here is a distinction papers actually ask — address bar versus search, Forward versus Reply, SMTP versus IMAP.

1Web browsing and searching
A web browser (Chrome, Edge, Firefox) fetches and displays pages. You type a full address in the address bar, or type keywords into a search engine (Google, Bing) to find pages.
SSC's internet module expects this everyday distinction: browsing opens sites; searching finds them; downloading and uploading move files to or from the network.
Figure. You type in the browser; the search engine ranks pages; results come back to the browser.
| Action | What you do |
|---|---|
| Browse | Open a known site or follow links in a browser |
| Search | Type keywords in a search engine to find pages |
| Address bar | Enter a URL such as https://ssc.gov.in |
| Search box | Enter words; the engine returns ranked links |
You already know the exact site address https://ssc.gov.in and want that homepage, not a list of related links. Where should you type it?
- A search engine's keyword box only
- The browser address bar
- File Explorer's search bar
A known URL goes in the address bar. A search box returns ranked results; File Explorer searches local disks.
2Downloading and uploading files
Downloading copies a file from the internet (or a server) onto your device. Uploading sends a file from your device to a server, cloud drive or form.
Exams often pair the direction with a scenario: saving a PDF from a site is download; submitting a scanned form to a portal is upload.
Figure. Download pulls toward your device; upload sends from your device to the server.
| Word | Direction |
|---|---|
| Download | Remote → your device |
| Upload | Your device → remote |
| Attachment (send) | File rides with an outgoing e-mail (upload to mail servers) |
| Save link as… | Common browser download path |
A candidate saves the SSC admit-card PDF from the website onto their laptop Downloads folder. Which action did they perform?
- Upload
- Download
- Format a disk
Remote file → local device is download. Upload is the opposite direction.
3Managing an e-mail account
Electronic mail (e-mail) sends messages over a computer network. An account has an Inbox for mail received, Sent for mail you dispatched, Drafts for unfinished messages, and usually a way to attach files.
When composing: To is the main recipient; Cc (carbon copy) informs others openly; Bcc (blind carbon copy) hides other recipients from each other.
Figure. An account folders mail: Inbox for arrivals, Sent for outbound, Drafts for unfinished.
| Piece | Role |
|---|---|
| Inbox | Messages received |
| Sent | Messages you have sent |
| Drafts | Unfinished messages |
| Attachment | File sent with the message |
| To / Cc / Bcc | Main / open copy / hidden copy recipients |
You must mail a PDF to a board address and quietly copy your supervisor without the board seeing the supervisor's address. Which recipient field hides the supervisor?
- Cc
- Bcc
- Subject
Bcc hides recipients from each other. Cc shows every open copy; Subject is the title line.
4Reply, Reply All and Forward
Reply sends your answer only to the original sender. Reply All includes the sender and everyone on To/Cc. Forward sends the received message to a new address while keeping the original in your mailbox.
If the exam asks how to send a received mail to someone else and still keep your copy, choose Forward — not Archive-and-recreate, and not Reply.
Figure. Reply hits the sender; Reply All includes other recipients; Forward opens a new outsider thread.
| Action | Goes to | Keeps original? |
|---|---|---|
| Reply | Original sender only | Yes, still in Inbox/Sent as usual |
| Reply All | Sender + To/Cc list | Yes |
| Forward | A new address you enter | Yes — original stays for your records |
| Archive | Moves mail out of Inbox | Does not by itself send to a new person |
In Outlook you received a circular. You must send that same mail to a colleague who was not on the original list, and keep the original in your mailbox. What do you use?
- Reply
- Forward
- Reply All only
Forward targets a new recipient and leaves your copy. Reply goes to the sender; Reply All hits the old list.
5E-mail protocols: SMTP, IMAP and POP3
SMTP (Simple Mail Transfer Protocol) sends outgoing mail between servers. IMAP and POP3 retrieve mail for a client: IMAP keeps mail on the server and syncs folders; POP3 typically downloads mail to one device.
You do not need server administration — only which protocol sends versus which receives.
Figure. SMTP sends mail out; IMAP or POP3 bring mail in from the server.
| Protocol | Job |
|---|---|
| SMTP | Send / transfer outgoing mail |
| IMAP | Read mail; keep and sync on server |
| POP3 | Download mail to a local client (classic exam contrast with IMAP) |
| HTTP/HTTPS | Web pages — not the mail-send protocol |
Which protocol is responsible for sending an outgoing e-mail from a client to the mail servers?
- IMAP
- SMTP
- POP3
SMTP sends. IMAP and POP3 are retrieval protocols.
6e-Banking on the internet
e-Banking (internet / net banking) means using a bank's website or app over the internet to check balances, transfer funds and pay bills — without visiting a branch for each task.
SSC lists e-Banking under Working with Internet and e-mails. Treat it as a secure online banking channel: login, OTP or 2FA, and never share passwords. UPI is a related India-specific instant payment rail often tested beside it.
Figure. e-Banking channels: browser net banking, mobile app, and ATM/card at a machine.
| Idea | Exam peg |
|---|---|
| e-Banking / net banking | Bank services over the internet |
| OTP / 2FA | Extra proof at login or payment |
| Phishing risk | Fake bank pages asking for passwords |
| UPI | Instant mobile payment system in India |
Which activity best matches the SSC syllabus phrase e-Banking?
- Formatting a Word document offline
- Transferring money using the bank's internet portal or app
- Defragmenting a hard disk
e-Banking is banking over the internet. Word formatting and disk tools are local PC tasks.
7Secure browsing: HTTPS and SSL/TLS
HTTPS wraps web traffic in encryption so data in transit is harder to read on the wire. SSL/TLS is the security layer behind that padlock in the browser.
Exams contrast encryption in transit with unrelated ideas such as compression or hashing alone. Prefer HTTPS sites for logins and banking.
Figure. HTTPS wraps HTTP in TLS encryption (port 443); plain HTTP on 80 is not private.
| Mechanism | Role |
|---|---|
| HTTPS | HTTP over TLS — encrypted web session |
| SSL / TLS | Cryptographic layer securing the channel |
| Compression | Shrinks size — not confidentiality |
| Hashing alone | Fingerprint / integrity check — not the full channel encryptor |
Which option best describes a common way to protect sensitive information while it travels between a browser and a website?
- Compression only
- Secure Socket Layer / TLS (HTTPS)
- Disk defragmentation
SSL/TLS (HTTPS) encrypts the session. Compression and defragmentation do not protect confidentiality in transit.
Notes
- Browse opens sites; search finds them with keywords; the address bar takes a full URL.
- Download = remote to device; upload = device to remote.
- E-mail folders: Inbox, Sent, Drafts; To / Cc / Bcc control who sees the message.
- Reply → sender; Reply All → sender+list; Forward → new address while keeping your copy.
- SMTP sends mail; IMAP/POP3 retrieve mail.
- e-Banking is banking over the internet; protect logins with OTP/2FA.
- HTTPS / SSL-TLS protects data in transit to a website.
Formulas
- SMTP = send mail; IMAP/POP3 = receive mail
- HTTPS = HTTP + TLS (encrypted web)
Exam traps & shortcuts
- Forward keeps the original and targets a new person — the usual answer when the stem says keep your copy.
- If the stem says padlock / secure site / data in transit, think HTTPS/SSL-TLS, not compression.
Reference tables
One row per mark that SSC's internet module keeps recycling.
| Fact | Peg |
|---|---|
| Browse vs search | Open known site vs keyword lookup |
| Download / upload | Remote→device / device→remote |
| Forward | New recipient; original kept |
| SMTP | Outgoing mail |
| IMAP vs POP3 | Server sync vs classic download-to-device |
| e-Banking | Bank services over the internet |
| HTTPS / SSL-TLS | Encrypt web session in transit |
