What does the future hold
The convergence of many different communication media on a single computer network platform encourages the exponential growth of computer network capabilities. Three major trends help shape the future nature of complex information networks:
Mobile users
With the increase in the number of mobile workers and the number of mobile devices, we are logically asking for more mobile connectivity to computer data networks. This demand has created a market for wireless services offering more flexibility, coverage and security.
New devices with superior capabilities
Computers are just one of the types of peripherals that today are involved in information networks. We are witnessing the emergence of a host of exciting new technologies that can leverage the available computer network services.
The features offered by mobile phones, PDAs, organizers, and converged pagers on unique portable devices that have seamless connectivity to service and content providers. These devices, once considered "toys" or luxury goods, are now an integral part of our communication. In addition to these mobile devices, there are also VoIP devices, gaming systems, and a variety of family and business gadgets that can connect to and use computer network services.
Increase in the number of services available
The widespread adoption of technology and the rapid pace of innovation in computer network services is creating a growing dependency phenomenon. To meet the requirements of users, new services are introduced while the previous ones are improved. When users feel comfortable with these extended services, they demand even more capabilities. The computer network is developing to meet this growing demand. People depend on the services provided on the computer network and therefore on the availability and reliability of the underlying computer network infrastructure.
It is incumbent on well-trained IT professionals and computer networks to keep pace with the ever-expanding network of users and services.
Career opportunities in the field of computer networks
Careers in information technology and computer networks are subject to increasing demand and are constantly evolving as are the underlying technologies and services. As computer networks become more sophisticated, so does the demand for employees with computer networking skills.
In addition to traditional IT professions (programmers, computer engineers, database administrators and network technicians), new network architect positions, e-commerce site designers, information security managers and home automation specialists are emerging. . Opportunities abound for daring entrepreneurs.
Even jobs outside the IT sector, such as those in the field of production management or medical equipment design, now require strong knowledge of the operation of computer networks.
In many large companies, technology managers cite the lack of qualified personnel as the main cause of delay in implementing new innovative services.
As we study the technology of computer networks, we will focus on the components of computer data networks and their role in the activation of communication. This course is designed to provide you with the computer networking knowledge you need to design and manage these evolving IT networks.
Network definition
A computer network is a set of interconnected equipment for exchanging information.
Advantage of the computer network
A computer is a machine for manipulating data. Man as a communicator quickly understood the value of linking these computers together so that information could be exchanged.
A computer network can serve several distinct purposes:
The convergence of many different communication media on a single computer network platform encourages the exponential growth of computer network capabilities. Three major trends help shape the future nature of complex information networks:
- the increase in the number of mobile users;
- proliferation of devices compatible with computer networks;
- expansion of the range of services offered.

Advantage of the computer network
A computer is a machine for manipulating data. Man as a communicator quickly understood the value of linking these computers together so that information could be exchanged.
A computer network can serve several distinct purposes:
- Sharing resources (files, applications or hardware, connecting to the Internet, etc.)
- Communication between people (e-mail, live chat, etc.)
- Communication between processes (between industrial computers for example)
- Guaranteed uniqueness and universality of access to information (networked databases)
- The multiplayer video game
- Networks also make it possible to standardize applications, we generally speak of groupware to qualify the tools allowing several people to work in a network. For example, e-mail and group calendars make communication more efficient and faster. Here is an overview of the benefits of such systems:
- Reduce costs by sharing data and devices
- Standardization of applications;
- Access to data in a timely manner
- Communication and organization more efficient.What does the future hold
