Rapid transfer of data

Files can be easily transferred and shared across the globe using the Internet [Internet: a global network connecting millions of computers ]. A file could be:

  • emailed [email: electronic mail - a message written or typed on a computer and sent electronically rather than by post ] as an attachment [attachment: a file that's 'attached' to an email is called an attachment ]
  • sent over instant messenger [instant messenger: an application that allows users to send instant messages (text) to one another ]
  • downloaded [download: the transfer of a file or files from one computer connected to the Internet to another ] from a website [website: a web page or group of web pages hosted on one web server and viewed in a web browser ]/web server [web server: a computer that serves web pages to users ]
  • accessed over a private network [network: a group of interconnected computers ]

Documents, eg a spreadsheet [spreadsheet: A spreadsheet is made up of cells, rows and columns. Each cell holds a piece of numeric (numbers) or alphanumeric (text) data. Cells can also contain formulae to calculate their contents. ], can be stored on a web server and then accessed via any computer with an Internet connection [Internet connection: a computer's or another internet-enabled device's connection to the Internet ] and a web browser [web browser: an application used to browse the Internet or view web pages ]. Collaborative working is possible too, where multiple people contribute to the same document.

This makes the world very small as far as transfer of data [data: information without context, eg a list of students with numbers beside their names is data, when it's made clear that those numbers represent their placing in a 100 metre race, the data becomes information ] is concerned. It has allowed many companies to outsource some or all of their operations. This is where companies transfer activities such as ticket processing for airlines or telephone banking queries to workers in a country where wages and running costs are relatively low. Often the time difference between the two countries gives even greater convenience.
