Unknown Technical Facts | Haven't Heard These Anywhere Before !!!!!!!!

These are some unknown technological facts that you may not have heard about it. I have a list a of these and I am going to tell you one by one.

So, let's get started.

1.

Which building in a town or city can be the most expensive? Is it a jewellery store? Is it a bank? No, the right answer is a data centre.

The data centres are most expensive because of too many hard-disks. You know that these data centres have huge number of expensive physical parts as well as the data they contain can also be expensive beyond your thought. They also have many servers and cooling machines and have a high labour as well as mechanical costs than anything else.

2.

This one is very common but none of us think in this manner. No any digital content can never be moved but only
can be copied. For example, if you are transferring a file from one drive to another then the file actually gets copied from the first one to the another one.

The difference is that the data stored in the first one gets removed from the registry only and not from the drive. If you delete something from a storage device then the data remains there but it only gets removed from the registry. And that's how all the file recovering softwares work and recovers your precious data after getting deleted.

3.

You can't listen or watch something on your computer on the internet unless that audio or video gets downloaded on your machine. Even watching videos on youtube, you have to load the video on your machine then it gets played. Every single must be loaded on your machine before it can be played online or on the internet. This is technically true and it is a fact.

4.

Your personal computers can run some commercial softwares for free for which some big companies have to many thousands of dollars to run it.

This is UNIX that you can run freely on your computer. There are other softwares like virtual machines, and SQL. The company give it to you for free because they know that you will use it for your own interest and you won't get any profit commercially using their software. But, if the big companies want that software they have to pay thousands of dollars that you use for free of cost.

5.

Nowadays you can find anyone's profile on Facebook. It made it easy to find anyone;s profile including your friends,family,relatives,teachers,etc.

But, do you know that there are 30 million active Facebook accounts who are
actually dead and do not exist in real world anymore. Facebook is thinking of bringing a new mode for those accounts. So,that their friends and family can switch their accounts to that mode. And there would be a difference
between live and dead people's accounts.

So, that's all and have a good day.
