Internet, Web and Email

Track: Computer Awareness for Banking and Recruitment Examinations
Level: Beginner
Coverage: Seven lessons (CA-06-01 to CA-06-07)
Practice: 84 original MCQs with individual answer explanations

An applicant downloads an admit card, an employee opens an office portal, a bank sends a confirmation email, and a family uploads photographs to online storage. All four activities use connected computing, but they involve different services and concepts. This module teaches how to tell them apart and how to recognize them in objective examination questions.

How to study: Start with the meaning and a real-world example, then learn the tables marked Fact to remember. Attempt the questions before reading their answer explanations. These are original exam-style MCQs, not unverified claims of previous-year questions.
