Basics of Network Technologies: Benefits of Networks

 A computer network is an infrastructure for the physical and software interconnection of computers, using standard communication protocols over digital connections to share resources provided by or placed on the network nodes. A wide range of physically stressed, optical, and wireless radio-frequency technologies that can be arranged in a variety of network topologies are used to create the connections between nodes.

A laptop network's nodes can be identified in a variety of ways, including as computers, servers, networking equipment, or modern-day hosts. By using hostnames and community addresses, they are identified. After the initial challenge, hostnames serve as memorable labels for the nodes and are rarely changed.

Network: What is it?

Two devices are considered to be in a community in the modern world if a process in one device can exchange data with a different technique in a different device. A node (a group of devices) or computer network is a medium for connections between nodes. A community is made up of a number of computer systems, servers, and networking tools that are all connected to the same resources, such as a printer or a report server. Both cable and wireless technologies are used to install the connections.

Networks of Different Types

Computer networks come in five main categories:

1. The local area network, or LAN

Systems connected in a small network, like one in a building or a small office, are less expensive. It uses Ethernet or Token-ring technology. Two or more personal computers can be connected via wires or cables that act as nodes and the information which is delivered quickly and is of high quality.

2. Personal Area Network (PAN)

The smallest computer networks can be used to connect devices with Bluetooth and other infrared capabilities. There are connectivity options available up to 10 meters. It shields an area up to 30 feet wide. With the help of PAN MAN, a single person's personal devices can connect to one another (Metropolitan Area Network)

3. Metropolitan Area Network (MAN)

A network that can be connected inside a city is known as a MAN (Metropolitan Area Network).It can take the form of Ethernet, ATM, token ring, and FDDI. It has a wider range. This kind of network could be used to link people with various organizations.

4. Wide Area Network (WAN)

 A network that spans an entire country or a larger population of people. Telephonic lines are also connected via WAN. The Internet is the largest WAN in the global network. Primarily employed by government organizations to regulate information and facts.

5. Virtual Private Network (VPN)

A network that was constructed by connecting a private community to public wires. You can create networks using a variety of structures. The use of the Internet as a channel for the transmission of information. These systems employ encryption and other security measures to guarantee that only approved users can access them.

Benefits of Networks

Data can be centrally stored on a main node (the document server), where they can be shared and made available to all users within an organization. Anyone can join a computer network who want to connect to a modern computer network, a small number of skills are needed. An individual problem may be resolved more quickly because a comprehensive approach is broken down into several more manageable approaches, and each is handled using all relevant tools.

Backup of records is necessary for reliability. If for some reason a device malfunctions, crashes, etc., and the data on one PC becomes compromised or inaccessible, a backup copy of the same data is available on another computer for future use, enabling smooth operation and uninterrupted handling.

The technology is regarded as being extremely adaptable because it gives users the chance to learn everything about fundamental concepts, like programming, without affecting their usefulness.

Through the device, security and data protection are also handled. No other person can breach the safety or security of data since only authorized device users are allowed access to specific information or applications.

WHAT DO LAYERS 2 AND 3 SWITCHES DO?

The terms Layers 2 and 3 are taken from the Open System Interconnect (OSI) version, which is a standard version for describing and explaining community communications. The OSI version has seven layers: the physical layer, the transport layer, the network layer, the statistics hyperlink layer, and the utility layer. Of these layers, the network layer is Layer 3 and the statistics hyperlink layer is Layer 2. The Layer 2 transfer and Layer 3 switches, respectively, are the switches that operate in those layers.

The routing feature is the primary distinction between Layer 2 and Layer 3. The primary distinction between a Layer 2 transfer and a Layer 3 switch is also this one. A Layer 2 switch prefers MAC addresses over IP addresses and is unconcerned with anything in a higher layer. All of the tasks that a Layer 2 switch performs can also be performed by a Layer 3 switch, also known as a multilayer transfer. Both static and dynamic routing are additionally possible. In other words, a Layer 3 transfer handles packet routing between unique VLANs as well as intra-VLAN communication and has both a MAC handle desk and an IP routing desk. Layer 2+ or Layer 3 Lite transfers are those that offer the best static routing.

The function of a Layer 2 switch is the exact opposite of that of a Layer 3 switch. Data packets at layer 3 could not be routed by layer 2 switches. Layer 3 switches use IP addresses for routing, in contrast to Layer 2 switches. It is a specialized hardware component used for data packet routing. Fast switching is possible with Layer 3 switches, and they have more ports. The main benefit of using Layer 3 switches is that they can route data packets without making additional network hops, making it faster than routers. They are a significant improvement over traditional routers in terms of performance. They do not, however, have all of the additional router features. Large-scale businesses frequently use Layer 3 switches.

Conclusion

 A network is any number of computers that are linked together through a telecommunications device with the intention of communicating and sharing resources. Companies would no longer be able to share resources and boost productivity more effectively without a network. Agency use of the Internet across vast areas was made possible by the WAN network. This allowed the company to hold conferences in far-off locations while using video conferencing and network information sharing. As you can see, networks offer the user who gives up many benefits.
