Computer Basics - Computer Application & Features

What is a Computer Application?

A computer application (or application software) is a program designed to help a user perform a specific task or solve a problem. Unlike system software (like the operating system), applications are made for end-users.

Examples:

  • MS Word → Writing and editing documents.

  • Google Chrome → Browsing the internet.

  • Photoshop → Editing images.

  • Tally → Accounting.

Features of Computer Applications

Most computer applications share some common features:

  1. User-Friendly Interface

    • Designed to be easy to use (menus, icons, buttons, shortcuts).

    • Example: Word processors with toolbars and ribbon menus.

  2. Task-Specific Functionality

    • Each application is built to perform a specific purpose.

    • Example: Excel for spreadsheets, PowerPoint for presentations.

  5. Productivity Enhancement

    • Speeds up tasks compared to manual methods.

    • Example: Accounting software reduces time and errors compared to manual bookkeeping.

  6. Integration with Other Software/Hardware

  7. Portability

    • Some apps can run on multiple devices or platforms (Windows, macOS, Android, iOS).

    • Example: WhatsApp Web and mobile app.

  8. Security Features
