The components of Computerised Accounting System are:

The correct option is: Data, People, Procedure, Hardware, Software.

A Computerised Accounting System (CAS) is an integrated set of components that work together to collect, process, store, and report financial and accounting data for decision-making. A complete computerized accounting system consists of five key elements:

1. Data: These are the raw financial facts, transactions, and figures input into the system for processing and storage.
2. People: These are the users of the system, including accountants, data entry operators, and managers, who operate the system, feed the data, and analyze the outputs.
3. Procedure: This represents the logical steps, rules, guidelines, and instructions followed by the users and the system to process data and perform accounting operations consistently.
4. Hardware: This refers to the physical equipment and electronic devices (such as computers, servers, keyboards, monitors, and printers) that run the system.
5. Software: These are the programs and applications (such as accounting packages like Tally, SAP, or QuickBooks) that instruct the hardware on how to perform specific accounting functions.

Other choices include specific accounting outputs or tools (like Ledgers, Charts of Accounts, or Reports) which are generated by or stored within the system, but they are not the primary, overarching components of the system itself.
