PC Maintenance Tips...

RUNNING SMOOTH...

Step one:Clean up any Adware and scumware seem. Often the sting in the tail is, the behind the scenes, installing of Adware or Scumware as it’s sometimes known. This usually consists of programs that run in the background and advertise various offerings which can be targeted to match your preferences. These programs take up valuable system resources and should be cleaned out.

Programs such as Gator (form filler) and Kazaa (music sharing) are well known examples of this but there are many others.

Step Two: Clean out your start-up files Nearly every program you load on your computer wants to be top dog. By that I mean when you install the program it usually sets itself up in your startup list.

This means that whenever you start up your computer the programs installs itself automatically into main memory whether you are going to use it or not and just takes up valuable resources that could be better utilised by programs you are using right away.

If you hit the Control-Alt-Delete keys once (if you do it twice you will reboot the computer and lose any unsaved work) you will be able to see all the programs that are running behing the scenes.

The more you have running that you are not using, the more memory will be taken up and the slower and less stable the system will be.

Things like Anti-Virus programs and “system tray” should be left running but many others can be removed.

Science Of Electronics

An electronic symbol is a pictogram used to represent various electrical and electronic devices (such as wires, batteries, resistors, and transistors) in a drawing of an electrical or electronic circuit. These symbols can (because of remaining traditions) vary from country to country, but are today to a large extent internationally standardized. Some symbols (such as those of vacuum tubes) become virtually extinct with the development of new technologies.

Circuit symbols are used in circuit diagrams which show how a circuit is connected together. The actual layout of the components is usually quite different from the circuit diagram. To build a circuit you need a different diagram showing the layout of the parts on strip board or printed circuit board.
