Principle Of Information Systems

A set of interrelated components that collect, manipulate, store, and disseminate data and info. and provide a feedback mechanism to meet an objective. It is the feedback mechanism that helps organizations achieve their goals.

Consists of raw facts,such as an employee number, total hours worked in a week, inventory part numbers, or sales orders.

When facts are arranged in a meaningful order, they become info. Is a collection of facts organized and processed so that they have additional value beyond the value of the individual facts.

Turning data into info. is a process which is defined as a set of logically related tasks performed to achieve a defined outcome.

The process of defining relationships among data to create useful information requires knowledge. It is the awareness and understanding of a set of info and the ways that info can be made useful to support a specific task or reach a decision.

Accessible, Accurate, Complete, Economical, Flexible, Relevant, reliable, secure, simple, timely, verifiable

Is a set of elements or components that interact to accomplish goals. Systems have inputs, processing mechanisms, outputs, and feedback. ex. car wash

Input, processing, output, feedback

is a single set of hardware, software, databases, telecommunications, people, and procedures that are configured to collect,manipulate, store and process data into info.

includes all the hardware, software, databases, telecommunications, people, and procedures that are configured to collect, manipulate, store and process data into info.

Consists of the physical components of a computer that perform the input, processing, storage, and output activities fo the computer.

Consists of the computer programs that govern the operation of the computer. Ex. payroll processing,customer billing.

Is an organized collection of facts and info., typically consisting of two or more data files. ex. verification system of a large bank

Is the electronic transmission of signals for communications which enables organizations to carry out their process and tasks through effective computer networks. ex. wired, wireless, or satellite tranmission.

Connect computers and equipment in a building, around the country, or around the world to enable electronic communication.

is the worlds largest computer network, consisting of thousands of interconnected networks, all freely exchanging info.

Involves in business transaction executed electronically B2B, B2C,C2C, business and public sector and consumer to public sector.

The use of mobile,wireless devices to place orders and conduct business.

Systems Investigation(Understand the prob), systems analyis (Understand solutions), systems design (Select and plan best solution), Systems implementation ( place solution into effect), Systems Maintenance and review (evaluate results of solution)

The knowledge of computer systems and equipment and the ways they function.

the knowledge of how data and info are used by individuals, groups, and organizations. It encompasses how and why technology is applied in business.

Cultural challenges, Language challenges, Time and distance challenges, Infrastructure challenges, Currency challenges, product and service challenges, technology transfer issues, state,regional, and national laws, trade agreements.
