Basic Elements of Information Technology

Software and Applications
Software is an important part of information technology which relates to computer applications that enable a company to generate, store, program, and retrieve data as and when needed. There are many software developed for different purposes. All operations in the business sector are carried out by software that are assigned for executing specific tasks. Without these computer applications the businesses wouldn't have been able to carry out their functions in a proper and efficient manner. Operating systems, ERPs, special purpose applications, and web browsers are some examples of different software.

There are some software which are exclusively built to contribute to the proper collaborative working of all sections of the businesses, which are known as Enterprise Resource Planning (ERP). These are complex applications which enable people to efficiently manage all functions and operations of all processes in the businesses.

Hardware Devices
These are various computer equipment that house the software. Devices like microcomputers, mid-size servers, and huge mainframe systems are some examples of hardware. Businesses have to maintain a huge collection of important data. For this purpose, they employ these devices which are responsible for storing confidential company data and retrieving it back when required. Other hardware devices include network devices that are used for providing Internet access to the businesses to work and communicate expeditiously. There are even devices which enable manufacturing tools and equipment to work accurately in the industrial sector.
