Hardware
There are many types of hardware collection devices used for different types of data. The devices that are used specifically to enter data into a computer system are referred to as input devices. An input device should be convenient to use, reliable and allow data to be entered accurately. The data may be in a number of
forms, including text, numbers, images, audio and video.

Software
Operating Systems
The operating system is the software that supervises and controls the hardware. It is responsible for controlling all the peripheral devices (input and output devices). The operating system contains specific software for each type of peripheral device.
On a personal computer, the operating system is usually stored on a hard disk and starts automatically when the computer is turned on. Loading the operating system into the computer’s memory is referred to as booting the system. Diagnostic checks on memory and peripheral devices are performed when booting the system. A small program that initiates the loading of the operating system is contained in memory.
The operating system provides a convenient interface between the hardware and its user. This is referred to as the user interface. The first widely used operating system was the OS/360 system. It was developed in 1964 for all computers in the IBM System/360 family. UNIX is a popular operating system that can be used on everything from personal computers to mainframes. Like many mainframe operating systems, UNIX time-shares the host central processing unit (CPU) to be able to run multiple tasks and support multiple users.
Data Entry
The collection of data involves entering images, audio, video, numbers and text.
The Internet as a collection source
The Internet is a source of data. It allows someone at one computer to collect data stored on another. Web sites present information on a particular topic. Each single document is called a Web page. In addition to the Web, data is collected from newsgroups. A newsgroup is a discussion group on a specific topic. People read newsgroups each day and they provide a large diversity of opinion and knowledge. The Internet also allows data to be downloaded. It is possible to download files containing text, graphics, animation, video, sound and software.

Data Entry
The collection of data involves entering images, audio, video, numbers and text.
- Images are created using graphics programs or are captured using a scanner, digital camera, video camera or the Internet. Clip art refers to prepared pictures that are grouped into topics such as technology, animals and education. There are millions of clip art drawings and photos available to suit most purposes.
- Video and audio are used in multimedia productions. Data collection should be carefully planned before any data is entered. The user should clarify a purpose, identify the audience and gather ideas.
- Text and numbers are entered into most software applications. The collection of data for a database often requires a great deal of research and the use of non-computer tools such as surveys and interviews. Spreadsheets should be carefully planned before data is collected. It is important to understand the relationships between the data, and how a spreadsheet will solve the problem.
