A network consists of two or more computers that are linked in order to share resources exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light.
Two very common types of networks include:
1 – A Local Area Network (LAN)
A Local Area Network (LAN) is a network that is confined to a relatively small area. It is generally limited to a geographic area such as a writing lab, school, or building. Services provided can include printing and faxing, software hosting, file storage and sharing, messaging, data storage and retrieval complete access control (security) for the network’s resources and many others.
Computers connected to a network are broadly categorized as servers or workstations. Servers are generally not used by humans directly, but rather run continuously to provide “services” to the other computers (and their human users) on the network.
On a single LAN, computers and servers may be connected by cables or wirelessly. Wireless access to a wired network is made possible by wireless access points (WAPs). These WAP devices provide a bridge between computers and networks. A typical WAP might have the theoretical capacity to connect hundreds or even thousands of wireless users to a network, although practical capacity might be far less.
2 – Wide Area Network (WAN)
Wide Area Networks (WANs) connect networks in larger geographic areas, such as Florida, the United States, or the world. Dedicated transoceanic cabling or satellite uplinks may be used to connect this type of global network.
Using a WAN, schools in Florida can communicate with places like Tokyo in a matter of seconds, without paying enormous phone bills. Two users a half-world apart with workstations equipped with microphones and a webcams might teleconference in real time.
WAN is complicated. It uses multiplexers, bridges, and routers to connect local and metropolitan networks to global communications networks like the Internet. To users, however, a WAN will not appear to be much different than a LAN. WAN connects all the networks that host all the systems and are assumed to exist on the entire senses due to its structure.
3 – What are Network Operating Systems?
Unlike operating systems, such as Windows, that are designed for single users to control one computer, network operating systems (NOS) coordinate the activities of multiple computers across a network. The network operating system acts as a director to keep the network running smoothly.
The two major types of network operating systems are:
- Peer-to-peer network operating systems allow users to share resources and files located on their computers and to access shared resources found on other computers. However, they do not have a file server or a centralized management source.
- Client/server network operating systems allow the network to centralize functions and applications in one or more dedicated file servers. The file servers become the heart of the system, providing access to resources and providing security.
4 – Conclusion: Building Your Network
As we’ve explored, understanding the various types of networks can significantly enhance your ability to design and implement effective communication systems. Whether for personal use, a small business, or a large enterprise, knowing the right network type can lead to optimized performance and improved connectivity.
To successfully build a network, you’ll need several essential components:
- Network Interface Cards (NICs): These allow devices to connect to the network.
- Switches and Routers: Switches connect multiple devices within a network, while routers manage traffic between different networks.
- Cabling: Ethernet cables or fiber optics are necessary for wired connections.
- Wireless Access Points: For wireless networking, these devices extend the network’s range.
- Network Security Devices: Firewalls and intrusion detection systems help protect your network from threats.
- Network Management Software: This software helps monitor and manage network performance and security.
