Adverse Effect of Technology on Our Daily Life

Since the Industrial Revolution (ঘূর্ণন) of the eighteenth and nineteenth centuries, there have been many advances in technology. The invention of the telephone, the cell phone, and the computer have greatly increased society's ability to and automobiles have enabled more efficient transportation. Television and the World Wide Web have provided entertainment for people of all ages. Technological inventions seem to have improved our way of life, but they have caused many side effects that have a negative impact on the world as well. Although there have been many advances in technology in recent years, this technology has had a harmful effect on social interactions. health, and the environment.

Technology has played a big role in the development of various industries, it has changed the banking sector, changed education, changed the agricultural industry, changed the entertainment word, in has restructured many businesses. The impacts of technology can not be measured because it is still changing the way we do everything. However technology also has some negative impacts. Below I have listed some of the impacts of technology in our lives both in a positive way and negative way.

1. Adverse Effect of Technology on Our Daily Life: 

• Exposure to wrong data: Though technology has made learning so easy and cheap, students get exposed to data which is not approved and many times they just copy and pastes this information they acquire online without any deep research on whether the data is correct. This has increased on the level of misinformation and failure of exams. My advice to students, is that, "Not what ever is published online is correct" analyze the data and discuss with friends before submitting that data.
• Digital divide is on increase: As much as we're embracing technology in most developed countries, there is a big group left behind and they might not even get closer to the way we use technology in the first world. For example, the invention of e-wallet is a good technology will help you to pay for anything via your iphone, but as good as this technology may be, many countries in the third world can not use the service.
• Lack or real life and Yes, social networks and text messaging technologies have played a very big role in connecting people more than before, but what is funny is that, the number of people who spend time alone is increasing. You will find a person spends more time in the virtual world chatting with strangers "virtual friends", a user will have over 500 friends on a specific social network, but they have no real friends in the real world, WHY? Because they spend most their time in the virtual world and give up on getting real friends, which results into loneliness and cyber-sickness.
• Virtual Reality Technology "Sickness". Now a days most airlines use this virtual reality technology to train their pilots on how to react effectively in adverse conditions. So during this training, the pilot will be presented with a challenge in a virtual reality form and they will be guided on how to over come that task. For example, many pilots are faced with bad weather, and defective engines. The pilot will be presented with the same challenge in a virtual reality world and they get training on how to over come the challenge. 
• E-cash is very easy to lose. As we try to replace cash money with e-cash, we are faced with problem of losing money very first. Why? E-cash is simply an electronic file, so this file ca be interrupted across the network and you will lose your money in a second. Today their many hackers online monitoring these electronic file transfers, though most merchants have formulated a trick of encrypting the files, but still these hackers find their way and access the data. Another top hole is the exposure of financial details to dangerous people. Most of this information is stored on our computers. However, when you connect to internet, your computer will be assigned with an IP Address, and an experienced hacker can access your computer via your IP and take advantage of all your financial details. 

m জন ছাত্র একটি বনভোজনে যাবে। বনভোজনে মোট খরচ হবে y টাকা। কিন্তু দুর্ভাগ্যক্রমে z জন ছাত্র বনভোজন থেকে তাদের নাম বাদ দিল। প্রশ্ন হলো, বাকি ছাত্রদের প্রত্যেকেই কত টাকা করে চাঁদা দিবে?

Number of students interested to go to picnic was m

Total cost of picnic was estimated to be y taka. 

$\therefore Cost per student was \frac{y}{m} taka,$

As z students withdrew their names, actual number of students who wanted to go is (m-z).

$\therefore$ Amount of money will have to be paid by remaining students $=\left(\frac{y}{m-z}\right)$ Taka. 

So, each of the remaining students have to pay more= $\frac{y}{m-z}-\frac{y}{m}=\frac{my-y\left(m-z\right)}{m\left(m-z\right)}=\frac{yz}{m\left(m-z\right)}TK$

More $\frac{yz}{m\left(m-z\right)}$ taka would pay each of the remaining students. (Ans)
