Since the Advanced Research Projects Agency Network (abbreviated as ARPANET; the foundation of modern Internet) had been developed by the United States Department of Defense (Kaminow & Tingye 2002, pp. 28-29), the Internet has been advanced endlessly. With the rapid advancement of the communication platform, our daily lives have been radically changed. Amongst many countries on Earth, South Korea is one of the most wired countries in the world (Internet World Stats 2016). So to speak about our Internet penetration, there are 3 major Internet service providers in South Korea: Korea Telecom (KT), SK Telecom, and LG Telecom (PCMag 2016).

Let’s return to the household of the person who I spoke with in week 2. In the second week, I spoke with my mother about her memories of watching a television. And in this week (4th week), we are going to discuss what kind of Internet access is in my mother’s house, and how many devices are connected to the Internet. Firstly, there is a broadband and mobile network connection in the house. In terms of the number of devices connected to a broadband modem, the approximate number of the devices is four including a laptop, smartphone, Wi-Fi router, and IPTV (Internet Protocol Television) device.

As I said early, there are three major Internet providers in the Korea, including KT, SK, and LG (PCMag 2016). Amongst the broadband and mobile network service providers, my mother is using SK’s broadband service (FTTH), and KT’s mobile network service (3G and LTE network). By the way, South Korea has one of Internet service coverages with the highest densities in the world as well as the fastest Internet speed and bandwidth (PCMag 2016). Along with Singapore, Hong Kong HKSAR, and other similar countries, the Korea is offering the highest Internet service quality, and I am really satisfied with these facts.

Besides, the Internet has changed her way of life. Especially, with the dissemination of Wi-Fi router and smartphone, this set up a ubiquitous computing environment. Literally, my mother does not need to sit in front of a computer or television anymore. She just needs a smartphone to surf websites, or watch television shows, and this can be done without space constraints.

I am also using a smartphone, there is also a FTTH connection at a place where I am staying at this moment, and the total number of devices connected to the Internet is eight, including a game console, Wi-Fi router, IPTV device, tablet PC, laptops, and smartphones. I am not sure my Wi-Fi router is capable of these many wireless connections.
