|Vocabulary Words||Definitions||Purpose||Type (If Applicable)|
|Information System||Kroenke (2014) stated, “Information system is a group of components that interact to produce information” (p. 10). This organized system collects, store, filter, create and process information with a combination of components that help to complete these processes.||The purpose of this system is to command, send and save information. In the healthcare industry, it is used to keep and maintain medical records and access them quickly.||Transactions Processing System, Management Information System, Executive Information System (Euromed Marseille School of Management, n.d.).|
|Hardware||Part of the components of the information system that you can touch and see. For example, the keyboard, CPU, mouse, all cables, and wires (Gartee, 2011).||The hardware obtains input, process data and gives output by following instructions.||Keyboard, CPU, wires|
|CPU||This is the brain of the computer. The acronym stands for Central Processing Unit this component of the information system has the arithmetic-logic unit and control unit, which manage the flow of information and all processes between all parts of the computer (Gartee, 2011).||The CPU makes all the processing, searching, calculation and sorting of information.||Single Core, Dual Core, and Quad Core|
|Memory and Storage||It is a group of components that hold information that is not on the CPU. This information can later be access in one of the elements of memory and storage.Some of these components are the hard drive, memory chips, RAM, ROM, and optical disks, among others (Gartee, 2011). The computer uses these parts to read and save the information.||It provides long-term and short-term storage of data.||Hard Drives, RAM, ROM|
|Input and Output Devices||The computer uses these devices to import and export information. For example, the keyboard, scanners, X-Rays and CAT scan are used to input information into the system. While the monitor, printers, and screens are examples of outputs. Input is when the data goes into the computer while the output is when the information exits the computer.||These devices provide the connection between the computer language and the humans. It translates the human word into the computer language and vice versa so the computer and human can understand and process the information.||Keyboard, scanners –Input Monitor, printers – Output|
|Software||Software tells the hardware what to do. It is called software because it is not tangible like hardware. The software includes operating systems and application software. For example, Microsoft Word is an application system, while IOS is an operating system both are software. Basically, without the software the hardware is useless.||Managing and processing information on the computer as well as helping people to do what they need to do on the computer.||Microsoft Word, Excel, Netflix|
|Operating Systems||It is the manager of the computer. It gives specific instructions to the CPU, keyboard, and other components. Gartee (2011) stated, “Operating system software consists of programs that enable us to work with a computer’s hardware” (pp. 78). It is a plethora of programs that control pure functions in the computer.||Manage the computer, sends and receive information, as well as organizing and keeps track of files and documents.||Windows, IOS|
Write a 150- to 350-word response to each of the following questions based on this week’s readings and your personal experience. Use your own words and provide examples to support your answers.
What is the difference between computer hardware and software?
The hardware is all the physical, tangible parts of the computer. It includes all elements inside and outside of the machine. Other components of the computer are hardware, like memory and storage, input and output devices, data ports, removable data storage and CPU. The software is all the intangible parts of the computer that gives the instructions to the hardware, as well as managing the hardware. It enables us to interact and use the computer to satisfy our needs. Examples of software are programs, applications, and operating systems. If we see the computer as a being, we can conclude that the body, brain, bones, etc. are the hardware while the connection between neurons is the software. The neuron connections tell the body and other parts what to do. When we search for information, we use the keyboard (hardware) to input the search, and the operating system (software) gives instructions to other hardware to explore.
Why is the use of information systems in health care important? Explain your answer.
The importance of information system in the healthcare industry relays in its efficiency and fruitfulness. This system storage and collects all the data from the patients in one place making it easier for physicians and other medical professionals to search and access. Contrary to paper files, the files in the information system are secure from loss, theft or damage. However, the accuracy of the data depends on the precision in which it is input. Information systems are a welcoming tool for physicians and hospitals because it allows them to improve the quality of their services. For example, in the case of a natural disaster patients that go to a hospital that has accurate records can receive fast treatment because they would have data on the patients’ medical history. However, an inaccurate input of information can be disastrous for any patient. Information systems should form part of any nation’s healthcare program to improve the health of the population and improve the quality of the healthcare system.
