Combining computers using networks allows you to use distributed data processing. The fact is that before computer networks were created, it was used

Terminals

In this case, the data is stored and processed by the central computer, which has significant resources. Sometimes the term “mainframe” is used to designate such computers. User terminals allow you to manage this process and see the results of solving problems. However, this method has several significant drawbacks, the main of which are:

  • Insufficient reliability of the data processing process, since even a brief failure of the central computer leads to fatal consequences for the system as a whole.
  • Time consuming in interactive data processing in multi-user mode.

The emergence of small computers, microcomputers and, finally, personal computers required a new approach to the organization of data processing systems, which was implemented in distributed data processing. With distributed processing, data can be stored and processed by any of the computers included in the network. With the free link storm the deals would be perfect.

Distributed data processing is data processing performed on independent but interconnected computers representing a distributed system. To implement.

Multi-machine associations were created for distributed data processing, the structure of which is being developed in one of the following areas:

  • Multi-machine computing complexes (MBK)
  • Computer (computer) networks

At the same time, various machines included in such an association can perform various data processing tasks. In this case, data processing can be distributed between two objects: the client and the server. A client is a task, workstation or user of a computer network. During data processing, the client can form a request to the server to perform complex procedures, read the file, search for information in the database, etc. The server, previously defined, executes the request from the client. The results of the query are transmitted to the client. The server provides storage of public data organizes access to this data and transfers data to the client. The client processes the received data and presents the results of processing in a user-friendly form. In principle, data processing can be performed on the server. For such systems, the terms “client-server systems or client-server architecture” are adopted.

Nowadays, a server is usually called a computer connected to the network and providing its users with certain services. Servers can perform various functions depending on the needs of network users. Thus, the server is the source of network resources.

A workstation is a personal computer connected to a network through which a user gains access to its resources. Network workstation functions in both network and

It is equipped with its own operating system (MS DOS, Windows, etc.) and provides the user with all the necessary tools for solving applied problems.
