All over the world the need for more laptops and computers increases each year. Networks have been part of our life. Probably everyone with a portable device (移动设备) has once logged on to a public WiFi network without paying for it, while they are having a coffee, on a train, in a shopping mall or at a hotel. However, is this kind of public WiFi network safe?

Some networks are better protected than others because encryption (加密) methods are used. Therefore, they are safer than others. But a survey in 2015 showed that more than 950 million records were not protected, including addresses, emails, birth dales, phone numbers, passwords and so on. These open WiFi networks are really not safe, because it is very easy for hackers to break into the operating system and get people's private information.

Most smartphones and laptops, by themselves, search and connect to WiFi networks. They usually prefer a network with a connection that has been used before. Hackers' devices are able to record these searches and look like the trusted WiFi networks. When these smartphones and laptops log on to the networks which are not real, hackers can easily steal their private information.

So next time, when we want to use our laptops or our smartphones in public places which offer free WiFi networks,please think it twice or take safe measures before using them.

Dear Dad,

Today I was at the shopping center and I spent a lot of time reading the Father's Day cards. But as I chose and read, and chose and read again, it seemed that not a single card said what I really want to say to you.

You'll soon be 84 years old, Dad, and you and I will have had 56 Father's Days together. I didn't think that you were too old. But the sad thing happened last week. I watched as you turned at the corner in your car. I didn't realize at once that it was you because the man who was driving looked so elderly.

Fifty years ago this spring, we planted carrots together in a garden in Charles City, Iowa. This week, we'll plant carrots together again, perhaps for the last time but I hope not. I don't understand why planting carrots with you is so important to me. Well, I don't quite know how to tell you this, Dad... I don't like carrots... but I like planting them with you.

I guess what I'm trying to say, Dad, is what every son and daughter wants to say to their dad today. Praising a father on Father's Day is about more than a dad who brings home money or shares a dinner. It's more about a dad deeply loving children who know everything and won't listen to anyone. It's about sharing. It's about loving someone more than words can say, and I wish that it would never end.

Love,

Jenny
