Computer software is still a major barrier to wide use of wireless information systems

Hardware is no longer the major obstacle to widespread use of wireless information systems. This is because number of different systems available for connecting. I will be discussing 3 of these, Wi-Fi, Bluetooth and 3G.

Standard Wi-Fi (wireless fidelity) is based on 802.11 specifications and is currently most common standard for wireless home and small office networks.

Term "software" was first used in print by John W. Tukey in 1958 [citation needed]. Colloquially, term is often used in sense of application software. In computer science and software engineering, software is all information processed by computer system, programs and data. Study of academic fields are computer software and software engineering.

In case of software development, is now generally accepted that publication in 1980 specifications for IBM Personal Computer, published by Philip Don Estridge IBM employee. Today his movement would be seen as the kind of audience-sourcing.

Until then, software is included with hardware original equipment manufacturers (OEM) such as Data General, Digital Equipment and IBM [citation needed]. When the customer buys the minicomputer, then smallest computer on market, team did ...
