Explain Advantages and Disadvantages of Fiber Optic Cable

What is a Fiber Optic Cable?

A Fiber Optic cable comes with the technology that uses glass threads called fibers to transmit data as pulses of light. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.
A Fiber Optic Cable transmits data as pulses of light through tiny tubes of glass. A Fiber Optic cable has a very narow strand of glass like human hair.

What is Bandwidth of a Fiber Cable?

Modern fiber cables can contain up to a thousand fibers in a single cable, with potential bandwidth in the terabytes per second.

Explain Advantages and Disadvantages of Fiber Optic Cable

Advantages of fiber Optic Cables

Fiber Optic cables are used to create very high speed networks.
Fiber Optic cables come with a very high information carrying capacity.
Electromagnetic waves cannot disturb the data passing through the Fiber Optic cables.
Fiber Optic Cables provide a more reliable and secure data transmission.

Disadvantages of Fiber Optics

Fiber Optic cables are very Expensive. Therefore Fiber Optic may be used only if we need a very high speed data transfer network in large organizations. Small organizations my not afford Fiber Optic networks.
A Fiber Optic media is difficult to install.

Types Of Network Topology

Today, we will types of network topology . What is a Network Topology? Definition of Network topology is the shape of the network . It is the physical layout of connected devices in a network. It tells us how a network will look like. Network Topology ( Definition 2) : The way in which the connections are made among all the network entities is called the topology of the network. Network Topology ( Definition 3) :Network topology specifically refers to the physical layout of the network, e.g., the location of the computers and how the cable is run between them. Network Topology ( Definition 4) :The physical topology of a network refers to the configuration of cables, computers, and other peripherals. The characteristics of a network depend upon the network topology selected. types of network topology Explain different types of network Topology Different network topologies are as follows: 1. Bus Topology 2. Ring Topology 3. Star Topology 4. Tree Topolo...

Basic Structure of HTML Document

Basic Structure of HTML Document The basic structure of an HTML document is given below: <HTML> <HEAD> </HEAD> <BODY> </BODY> </HTML> The above format shows that an HTML document starts with <HTML> tag and ends with </HTML> tag. It is also clear that an HTML document consists of two main sections: Head Section Head section is used to specify a title of the web page, normally. There are some other uses of Head section too, like linking external style sheets and Java script code, etc. Head section starts with the <HEAD> tag and ends with the </HEAD> tag. <TITLE> tag is used to display a title of...
