Technology has become one of the most important tools in our daily lives today. Every year, leading teams of engineers and technicians work to develop new technologies and ways to make our lives and work easier. It is completely correct to say that the technology is not the same as it was over 15 years ago. Today in our daily life we ​​have the best systems and components that make every device efficient and smarter. For example, PCs and smartphones today combine new technologies and materials, new software and what makes it possible to send or receive information more easily and quickly. But, with all the technology available and new data to be shared, the need to make networks more efficient has become a challenge over the years. I think that networks today in our daily lives are essential for the office and large companies. Networks maintain the balance and flow of information not only in buildings and businesses because they have become necessary wherever there are multiple devices connected to share and manage information.

Networks are mostly used to connect these devices and computers to the Internet. We can also have scanners and printers connected to the same area and network. There are different types of networks classified based on use and characteristics. In this article, I want to discuss some of the most important features and ways that make connection possible in a network. First of all, there are different network arrangements, what is called topology and when it comes to topology we have different types of physical or logical topologies. A physical example is bus topology, ring topology and star topology. Furthermore, we can find different types of networks such as peer to peer network and client server network. Another important point to discuss is that depending on the size and amount of information managed, networks are divided into categories, for example LAN (Local Area Network), MAN (Metropolitan Area Network) and last WAN (Wide Area Network). Each of these categories answers a different question, taking the example of a small business that has at least 20 connected computers and multiple printers and scanners. Each workstation can manage and share information. The data can be stored on a server and have less risk of losing this information making it simple and safe if we need a backup. Continuing with this example another advantage of having a network is that all data can be transferred quickly and easily avoiding the use of external devices to move information such as a USB. Additionally, each workstation can have the advantage of using the same printer and scanners as the others. For some companies, the efficiency of the networks also depends on the connection. Two basic methods to connect a network can be wired or wireless connection. Others such as fiber optics are very efficient because instead of copper wires they use glass or plastic which transfer the light. Optical fiber is faster than other networks connected for example with coaxial cables. Even a hundred times faster than twisted pair cables. On the other hand, we can connect a network using a wireless LAN. A wireless network connects different devices to each other but wirelessly using infrared or radio waves to transfer the information we want. Today wireless connection is very popular because the installation.
