P.1.1: The role of computer systems in different environments


Computers are a General purpose machine, commonly consisting of digital circuitry, that accepts (inputs), stores, manipulates, and generates (outputs) data as numbers, text, graphics, voice, videofiles, or electrical signals, in accordance with instructions called a program (, 2013).

Role of computers is different environments

Computer revolution has transfigured our society. Almost in every disciplinary of life, CIS (computer information system) play an integral role. Computers have become an essential requirement for our daily living, imagining our modern life without computers is very hard to comprehend. All over the world individuals and organisations rely on computers for a diversity of uses i.e.; personal, social, banking, businesses, educational, hospitals, gaming, transportation, etc… To illustrate the scale at which computer systems are used in different environments is too vast.

To better the flow of patient information for ease of access, improves patient care quality and patient safety over all. Another benefit is the usage of Electronic Medical Records (EMR) which helps the doctor prescribes medication efficient and accurately (, 2013).

In conclusion computers play a crucial and a very beneficial role in the hospital environment, it betters the chance of getting the proper treatment by providing patient health information more accurately when needed. Accuracy, speed and access to data, the computer information system, in this case hospital information system as transformed the healthcare industry.
