1. Discuss how and when data communication is started in Ethiopia and in globally?
Data communication in Ethiopia and globally typically starts with the establishment of a network connection between two or more devices. This can occur through wired connections (such as Ethernet cables or fiber optics) or wireless connections (such as Wi-Fi or cellular networks).
In Ethiopia, data communication started to gain traction in the early 2000s with the introduction of mobile phone services and the expansion of internet infrastructure. The government has since invested in improving the country's telecommunications network, enabling more people to access the internet and communicate with each other electronically.
On a global scale, data communication has been evolving for decades. The development of the internet in the 1990s revolutionized communication, connecting people and devices around the world. Today, data communication is an integral part of everyday life, with billions of devices connected to the internet and exchanging data in real-time.
Data communication can occur at any time, as long as the devices involved are connected to a network. It can be initiated by a user sending an email, accessing a website, or making a phone call, among other things. With the advancement of technology, data communication is becoming faster, more reliable, and more accessible, shaping the way we interact and communicate in our personal and professional lives.
