Chapter 7: Computer Fundamentals, MS Office & Internet Basics

7.1 Computer Fundamentals

A computer operates on the Input-Process-Output cycle. Core hardware includes the CPU (Central Processing Unit), RAM (volatile working memory), ROM (non-volatile firmware storage), and storage devices (HDD, SSD).

7.2 MS Office Basics

MS Word is used for word processing (document creation and formatting); MS Excel is used for spreadsheets (tabular data, formulas, and basic calculations); MS PowerPoint is used for creating presentations.

7.3 Email and Internet Basics

Email functions include composing, sending, and receiving messages, with attachments and cc/bcc options. Web browsers (e.g., Chrome, Firefox) are software used to access websites via the internet. A URL (Uniform Resource Locator) specifies a web resource's address.

7.4 E-Banking and Digital Services

E-banking encompasses internet banking, mobile banking, and ATM services, all frequently tested given policing's interface with financial-crime awareness (e.g., recognising online banking fraud patterns).
