Just imagine, At the end of a busy day, you are sitting on the sofa and you need a hot cup of tea… You just thought for a cup of tea, and it step to you! Don’t think me a mad or I’m not joking! This impossible thing can be possible by the help of BMI or Brain Machine Interfacing Technology!
What Is It?
Brain Machine Interfacing is such a technology, by using which a device can work by taking Neural Signal from a human brain! Especially it’s being designed for those patients who are severely paralyzed! Basically scientists are designing this technology for severely paralyzed patients that they can react with the world as a normal human being!
Base of BMI
When any part of our body gets paralyzed, all the sensors of that part get disconnected from our brain! Means, if our brain sends a signal to that particular paralyzed part of our body, it is unable to get that signal, BMI works here! Its main purpose is to take and understand those signals, analyze it and then sending it to that part of our body! By using this system, user can move cursor on the computer screen also! But these all are imaginations! To do it in real, all the scientists of IEEE and others are in experiment!

All About Windows Registry

What is Registry?
Registry is a database where Windows stores all types of settings and option related information, in other word, it consists of all information regarding hardware, software, users etc.
Now, in place of Win 95 or 98, registry was build up with two hidden files - USER.DAT & SYSTEM.DAT, but now it consists with another file. Named CLASSES.DAT
The structure of registry:
Registry is a Hierarchical Structure, just like our disk’s directory tree or Windows explorer. Now if we run the registry editor (Start -> Run -> Regedit), then we will find six main braches, called HIVE. Each hives contains some keys, now every key contains some subkey or value. This value stores all the information in the Registry!
All The Six Hives Of Registry.
1. HKEY_CLASSES_ROOT – It contains all the information related to File Association, OLE and Windows Shorten.
2. HKEY_CURRENT_USER – It consists of all the information for a particular active user who is in log on condition, e.g, logon names, desktop settings or start up menu etc.
3. HKEY_LOCAL_MACHINE – This hive contains all hardware and software related information.
4. HKEY_USERS – It contains all information related to users. For every user, there exists a SID subkey.
5. HKEY_CURRENT_CONFIG – It stores hardware configuration setting related information of current user related to HKEY_LOCAL_MACHINE.
6. HKEY_DYN_DATA – It stores all information about plug-n-play devices.
