Preface: An Introductory Note on Computers
Information Technology for the Health Professions is not a book about computers, but rather a look at the myriad uses of computers and information technology in health care. A brief overview of a few basic computer terms will be helpful in understanding these concepts.
Today, computers are used in every aspect of our lives. You have a small computer called a smartphone or a tablet in your pocket or a larger desktop computer on your desk. Whatever their size be and whatever they look like, all computers have some things in common. The tangible parts of the computer you can touch are called hardware: Input devices (a mouse, keyboard, touch screen, or microphone) let you enter data into your computer; output devices (a screen, printer, or speaker) let you get information from your computer. Inside your computer is some processing hardware (a central processing unit or CPU in a desktop computer), which turns the data into information, that is, adds 3 plus 4 and gets 7 as an answer. All computers have some storage to hold information and instruc-tions and some memory to hold current work. On a desktop computer, the storage is called a hard drive. All computers need instructions to tell them how to perform tasks. These instructions are called software programs and are usually stored in the computer. The instructions that tell the computer how to run are called system software. The most impor-tant system software is the operating system. Application software tells the computer how to perform specific tasks. Word processing software for text, spreadsheets for numbers, database management software for organized lists, graphics software that allows you to create presentations using images, and communications software that allows you to con-nect to the Internet are common examples of application software.
Almost all computers are connected to a large World Wide Web of interconnected computers called the Internet. Some computers, such as the Chromebook, use the Internet to store much of its software, information, and data. But all of us, if we use a smartphone, are connected. We use a wireless connection like Wi-Fi. When you access data and pro-grams from the Internet and save information on the Internet, that is called cloud comput-ing. The part of the Internet that is easiest to navigate is called the World Wide Web and is organized as pages and stored on websites. The Internet of Things (IoT) refers to intercon-nected devices. Devices can refer to almost anything that can electronically share data. They include cars, smart TVs, heart monitors, and buildings, to name a few.

A note on our point of view: Over the last several years, politics and science have clashed over many issues including climate change and whether human action is responsible. This is not a debate within the scientific community, which has achieved consensus. We take the consensus of the scientific community as our point of view.
