Technology has made anything comfortable and precise and the technologies are very smart these days. In general case the people know that smart technology as a smartphone. But there are many technologies in these last few years which are really smart.
We might have heard or we also have seen on the movies about the automation of work like some robot are making foods, the water is heated for bath time, door is opened when we go to our room, the lights goes off by the smartphone, etc.
We have seen such many cases but we may not know that they can be real. There is a new concept in information technology called "Internet of things" which is known as IOT in short. It says that everything that we see like vehicles, house door, refrigerators, electric wires, taps, ovens, etc. can be connected to the internet. They can be programmed and make them to help us as our requirement.
The very good example in the context of our country can be the Street lights. Street lights go off during the daytime and goes on automatically at night time. It is due to the IOT. There is a sensor connected which senses the intensity of UV rays of sunlight and it goes on if the intensity of UV rays is low. So it gets on during the night time and the very dim climate. It gets charged itself and functions properly according to the requirement programmed in the sensor.
Similarly the very popular Social Networking site FACEBOOK has introduced the system called "Jarvis". The founder of Facebook Mark Juckerburg has revealed a video in which it is show that he gets alarm at the morning. And at the bathing time the water gets warmed and if any relatives come to the gate of his house, the system informs the Juckerburg. This is also the best examples of the IOT.
Actually IOT is the combination of Information Technology and electronics and communication. It can develop new technologies every day. Because there are many things in the universe and they all can be connected to the internet and they have their IP address.
Recently Nepal has become load shedding free but electricity leakage is still there. As a student of Information Technology I am very sure that it can be controlled by the use of IOT. We can develop many devices to calculate the current passing through the wire and connect them in different points like within 1KM distance. Where ever the current gets decreases, we find out the leakage areas and again we can add more devices within that area to find out the exact leakage point. This is the simple example of application of IOT in our country according to the recent scenario.

Everything has it two sides. IOT also has some drawbacks. It is said that IOT devices are very vulnerable as security measures are not applied properly. Heart is the delicate organ of human body. There is a case where some person made his pacemaker automatic using the IOT concept. And someone hacked into that pacemaker and increased the Heartbeat and he was dead. Similarly, if we have used smart AC to maintain the room temperature and if someone hacked into the AC and increased the temperature to 1000 C then what would happen to us.
The things have many purpose and we should use them for human benefits. Without development of technologies, development of nation is limited. Time is very precious in this era. Let's think positive and develop new technologies to solve the difficulties in our daily life. We students like to bunk the class sometimes. What if we build a System that record the attendance of student and informs the guardian if the student is absent. It would be great fun. Lets do this.
