Advantages and Disadvantages of Wired and Wireless Networks
The evolution of technology has led to the development of various networking systems. These systems connect devices together for efficient communication and sharing of resources. Wired and wireless networks are two of the most popular types of networks available today. Both types of networks have their own advantages and disadvantages.
Optical fiber is a type of dielectric (insulating) material, such as glass or plastic, capable of transporting light. High-speed data can be transmitted through optical fibers by total internal reflection of light. The biggest feature of optical fiber is that it transmits light signals instead of electrical signals. Currently available optical fibers have a data transmission rate of 100 Mbps to 2 Mbps.

Asynchronous data transmission is one of the three methods of data transmission. In asynchronous data transmission, sender or source system sends one character of whole data at once to the receiver or destination system.
Data transmission speed is the rate of transferring data from source to destination. It is also referred as Bandwidth. Unit of bandwidth is Bit Per Second or bps. This is also called Band speed, which is the number of bits transmitted in a second is bps or Bandwidth. There are 3 types of Bands which are as follows
Unlike star topology or mesh topology, a bus topology is a multi-point connection between the nodes or devices on the network. A long cable works as backbone of the network. All the different nodes in the network connects at different points on the main cable. A connection point in the main cable for a node or device is the nearest point for the node.
Star topology is one of the four basic topologies of network communication. In this topology, all network devices connects to a controller or hub. This controller or hub enables communication among the network devices. Devices does not connect directly to each other as in Mesh topology. Each device sends data to another device through this hub. And when the hub receives a message, it relays the message to its destination device. As all nodes or devices connects a point, it is called an star topology.
Mesh topology is one of the four basic topologies of network communication. This is a point-to-point connection. That means, each devices in the network connects to each other device directly. Mesh topology offers speedy connection between devices due to dedicated communication channel.
A network system enables data communication between 2 or more devices. Communication links or channels connects these devices. There can 2 types of connection possible; point-to-point and multipoint connection. Both of these connections has their advantages and disadvantages and use cases.
Based on the direction of data from sender to receiver, there can be 3 types of transmission modes which are as follows
