A robot is a machine that is programmed to do jobs that are usually performed by living persons.

• Robots can be programmed to do different tasks.
• A computer that can measure the world around it can take reliable action. Robots are computers that do this.
• A robot’s arm can be programmed to see the outline of a car and to paint all over it. Its reliability at doing this depends on the program it uses. If the program only lets it see the overall outline of the car, then it might continue to point it all over even if there is no door in position.
• A computer is only as intelligent as its program.
• A reliable robot’s arm will have position sensors. The computer can position the arm, and then use information from the sensor to check that it has put the arm in the right place. It can make corrections if necessary.
• Computer control system unlike robots may only be able to carry out one task. But they will be able to do this one task quickly, reliably and cheaply.
• A computerized production line needs no tea breaks, sleep or holidays. It can save money because lesser wages have to be paid. The initial cost of design, manufacture and installation may be high, and the system still has to be looked after and maintained.

Electronics

Electronics are system that control things by switching on and off tiny electrical circuits. The switches are not like light switches on the wall, but work automatically. A computer works with the help of electricity.

Well nowadays everyone is using computers...and some of them don't know what a registry editor is.....so this is a tutorial

Definition Of Windows Registry:

The windows registry is a database that stores settings and options for Microsoft Windows Operating Systems. It contains information and settings for hardware, operating system software, most non-operating system software, and per-user settings.

Apart from what you can do with this Registry there are some malware programs or worms or viruses that would simply affect this windows register and change the settings for example:

Example; Windows Task Manager:

In windows operating systems the task manager gets disabled and you can't do anything but you will get a message saying "The administrator disabled your registry" even when you didn't do such things.....so just follow this simple trick to re-activate your Task Manager( TESTED works perfectly) using registry editor

There is a registry key that will disable Task Manager, although it’s not always clear how or why it was set to disable. In many cases the problem is related to spyware, so you should also scan your computer.

MANUAL STEPS TO ACTIVATE Task Manager:

Open up regedit.exe through the start menu search or run box, and then navigate down to the following key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System

On the right-hand side is a 32-bit REG_DWORD value named DisableTaskMgr with one of two values:

• 1 – Disable task manager
• 0 – Enable task manager

Just double-click and change the value, or even delete the key. The change should take place immediately.

Thats it the simple way to re-activate your Task Manager.....

I'll meet you soon with more registry editor tricks..
