With the proliferation of micro-computers, the concept of distributed computing has emerged. In distributed computing, a number of computers are dispersed in different parts of an organization and inter-connected using special cables, telephone lines or other telecommunication media. This allows data and programmers to be shared and also provides for some new types of application such as electronic mail. Electronic Mail moves messages through inter-linked computers/terminals.
To support such networking special electronic devices such as modems an network inter-face cards are often fitted into micro-computers. For example, a blinds company who are selling vertical blinds and roman shades online, they are having inter-linked computers by which they are sending their marketing emails. Another example is a company who are providing term life insurance rates online, they are using lead management tools by which their online leads are transfer to their insurance software and from that insurance software they are distributing their leads.
As with large computers, micro-computers have operating systems to enable the user to easily interact with the machine. These operating systems are similar to those on large machines except that they are much simpler. This is because the majority of micro-computers are not multi-terminal machines – only one user has access to the machine at any time. In this situation the machine is the personal computer of the user. Personal computers are used for a variety of tasks. The most common applications are:
- Word Processing
- Financial Analysis
- Data Base Access
- Graphics
- Accounting
Computers in Management
