Personal Computing: before and after
Thursday, September 18th, 2008In today’s world, a PC might be one of the tablet computers, laptop computers, or desktop computers. The most well-known operating systems, i.e. OS are Linux, Mac OS, and Microsoft Windows, whereas the most well-known microprocessors consist of x86-compatible central processing units, i.e. CPUs. The software applications pertaining to PCs are inclusive of games, databases, spreadsheets, word processing, and a series of special-purpose and personal productivity software. Contemporary personal computers usually have dial-up or high-speed connections to Internet, thereby permitting access to www, i.e. World Wide Web, along with a broad range of the other resources.
A personal computer might be one of the home computers, or might be located in office, usually connected to LAN, i.e. local area network. One of the distinct characteristics is that computer is basically made use of, on an interactive basis, by a person at a time. Such a thing is just contrary to time-sharing or batch-processing models which permitted huge expensive systems for being used by several people, generally at same time. It’s also in complete contrast to big data-processing systems that needed full-time staff for operating efficiently.
Even though early owners of PCs generally were supposed to have written programs of theirs for doing anything which is of great use with respect to machines, users of today have the access to broad spectrum of non-commercial and commercial software that has been easily installed.
