Guide on making websites or portal project management. This requires, first of all, technical skills of documentation (indexing, classification), as well as a certain culture of modern information systems and various tools for processing and broadcasting on the Internet, so there is a need for a reminder of some concepts related to ICT. In addition, the general introduction should highlight the typology of websites, the interest and desirability of the website for the documentation center.
The term network precedes calculations, and it can be understood as a set of elements interconnected by a set of paths. This is how we talk about the road network, the sea network, the railway network … The term has evolved over time and includes any group of people gathered as part of a joint activity. We are talking about networks of terrorists, networks of documentaries, networks of Masons, etc.
For computers, a network refers to a set of computers, and sometimes terminals, connected to each other to exchange information and programs or to share resources (printer, scanner). In this case, the concept of a network reveals the idea of sharing, sharing resources. This sharing most often works in client / server mode. The client here represents the user’s computer, which makes a service request, sends a request to the host computer, which serves as a data storage place. This server computer, after analyzing the client request, sends information corresponding to the requested service.
Computer networks typically vary in geographic coverage. This is how we talk about a wide or international network when computers are at a distance of several hundred or thousands of kilometers. These types of networks are called WAN (wide area network). The most famous of them is the Internet. There is another type of network whose computers are located at a distance of several meters to several kilometers. These are local area networks, in English LAN (local area network). Between these two networks there may be intermediate networks, such as metropolitan networks, whose computers are in the same city.
A protocol is a set of rules (codes) that must be followed to establish the exchange of information between computers. These rules govern communications between computer systems.
Website design is very popular today, but its significance remains little known to a wide audience. We then decided to explain this after the terms network and protocol, to facilitate understanding. The Internet is primarily a physical network, that is, a set of interconnected communication networks in the world. Then it can be understood as a network of networks in the sense that it connects millions of computers around the world and which do not necessarily belong to the country, do not necessarily work with the same systems and often do not contain the same types of information. Given the multiplicity of computer networks and protocols and satisfying the need to connect these networks, the Internet offers to define a set of protocols common to several networks, and at the same time implements the physical and logical principle of a global network connection method. Therefore, the Internet should be defined as a global computer network consisting of a set of networks connecting millions of computers of various types that can exchange information. This connection is most often made using public and private telephone lines.
The history of the Internet goes back to the Cold War in 1969 with the Pentagon’s ARPANET program. Today, the networks that make up the Internet belong to academic institutions, government and international agencies, non-profit associations, public and private companies, etc., which provide access to their information. The Internet is not owned by anyone, and no one can claim a monopoly, even the American army, which is at the forefront.
Thus, the Internet is sometimes defined as a repository of knowledge, sometimes as a large post office, a sound bank (disco), a library of image banks (video library) … The Internet, so to speak, contains all kinds of data and simultaneously fulfills various social roles that science will leave to humanity.
