Fiber-optic communication has transformed telecommunications. Data is now transferred at very fast speeds around the world. Fiber-optic communication transmits electronic signals in the form of light from one place to another through an optical fiber. A fiber optic transmission system consists of 4 major components: transmitter, fiber optic cable, repeater, and receiver. All four basic components work together to transfer data in the system. The transmitter receives input data in the form of electrical

boundary and the incident angle is greater than the critical angle, the wave cannot pass through and is entirely reflected. The critical angle is the angle of incidence above which the total internal reflection occurs. This is particularly common as an optical phenomenon , where light waves are involved, but it occurs with many types of waves, such as electromagnetic waves in general or sound
under developed countries still struggling to reap the maximum benefits of the technology, developed countries are planning to move forward with its new version termed as light fidelity (Li-Fi). This article aims to introduce the working, progress, advantages and limitations of this (Li-Fi) technology in comparison to Wi-Fi technology. Wi-Fi is the name of a popular wireless networking technology that Fig.: Wireless Fidelity (Wi-Fi) to Light Fidelity (Li-Fi) uses radio waves to provide wireless high-speed
Tablets and other wireless devices.Data communication and networks are driving in the capacity of wireless devices. Wi-Fi is more popular today but now new technology Light fidelity(Li-Fi) is establish in 2011 by German Physist that is 100 time faster than Wi-Fi.InLi-Filight has a medium of communication .Hence ,it bandwidth is in Tera Hertz range as compare to Giga Hertz of Wi-Fi. It is based on optical wireless communication. Optical wirless communication is based on unguided propogationmedium
"the competitive advantage nations", he make a research in ten leading trading nation. It also referred to the Theory of National Advantage. It's designed to help government to understand the competitive advantage. It suggests that the national home base of any organizations are playing a supportive role in shaping the size or scoop to which it is likely to achieve advantage on a global scale. This home base provides basic factors, which support organizations from building advantages in international
IV. Advantages of Li-Fi over Wi-Fi Technology [9] Wi-Fi Li-Fi A. TRANSMISSION SECURITY: From the security point of view, Wi-Fi is less secure as radio waves can penetrate through walls. They can be traced. If someone has knowledge about this and has bad intentions, they can misuse it. This create a major security issue. Li-Fi is based on data transmission through visible lights. Li-Fi is secure as light rays cannot penetrate through walls. They cannot be misused and traced by other People, who
• Terminator stops signals after reaching end of wire to prevent signal bounce. • Bus topology may have problems while multiple hosts sending data at the same time. Therefore, bus topology uses CSMA/CD technology. Advantages and disadvantages of bus topology: • Advantages:- o Low cost o Easy to connect/ add a computer or peripheral to bus. o Requires less cable length than a star topology. o No need to purchase any additional devices such as switch and hub. • Disadvantages:- o Entire network
A few numbers of Pakistanis consider CPEC (China Pakistan Economic Corridor) will prove as East India Company for Pakistan. Moreover, the others have a few reservations as the poor strategies and interest rate of the lease for CPEC are not in the favour of national interests. Here, we will scrutinize multi-facet aspects of China Pakistan Economic Corridor. Firstly, I will suggest that you visit the website of CPEC. After that, you will realize that CPEC is the part of OBOR (One belt one road). 64
of all countries have fewer than one out of 20 people with Internet access. From this information, as well as educational data, the ITU was able to compile an index that measures the overall ability of citizens to access and use information and communication technologies. Using this measure, Sweden, Denmark and Iceland received the highest ranking while the African countries Nigeria, Burkina Faso and Mali received the
