Networks are a group of computers that are linked to each other by means of a communication tool, the aim of which is to facilitate the process of exchanging information and data between them quickly and easily and with less effort. As is well known, the Internet is the largest example of the largest network ever, as it contains a large number of actors. The Internet is defined as a group of interconnected networks that link a large group of computers spread all over the world to facilitate the process of communication between them, and facilitate the exchange of data and information.
Internal computer networks
Internal computer networks are defined as the network that binds in its communication between a group of computers located within a limited area, as is the case in companies, institutions, schools, and companies, and is similar in its connection to the Internet, but it differs from it with the limited information and data permitted to be transferred between the parties to the network. As institutions, regardless of their type or background, work to block sites that do not serve their interests, in return, open the way for the passage of data and information that serves their interests, and the interests of their parties, from authorized employees or users of the network.
The difference between the internal network and the external network
If the internal network is the connection of more than one computer together in one place together, so that allows you to control the rest of the devices from one central device, that is, in a more accurate sense, this network produces one large computer whose area is the total area of all the devices connected to the network, then the network External differs from the first in that it links several branches in different places together, as it connects the branches through the server of external networks in order to link the accounts of more than one branch together, while we find inside each branch more than one device, it is a complex process through which Connect the devices of each branch to an internal network, then connect the branches to an external network. Because branches are often in different remote locations, all data is collected so that it flows into a single server through the external network.
Internal network features
• ease of transactions; as you do not have to go personally to complete a work to the authority concerned with this work, such as the need to complete a transaction, which exempts the employee who is completing this transaction from going to the competent authority, all he has to do is write to the relevant authority via the network and complete his work Smoothly.
Ease of communication between users authorized to enter the network.
• The ability to link the company’s internal systems and master databases in an internal collaborative system.
Ease of transferring files between parts of a single organization.
• The cost of establishing a network is low compared to its many benefits.
Rich and collaborative information environment.
Reducing information distribution expenses.
• Multiple ease of use for a single program or application, and secure interactive applications (texts, videos, audio clips).
• The ability to expand or reduce, according to the need of the institution.
