       Working of Antivirus

 

                                          Explained!!!

Hey DAa friends,
Many of You, Whenever You Turn on Your PC and then starting up the internet connection get this notification of antivirus software saying "DAa Updates for software are available " or "software is updating" , After seeing this some of You may get frustrated that why is it so, that whenever I start up my Computer it asks for updating?

The answer Here in this case is simple. But In order to understand this you have to know that how the antivirus works.
Basically DAa Antivirus software is nothing but has a huge collection of programs. Now whenever you start your PC or insert a Pendrive , The very first thing an antivirus will do is that it will start a check for detection of virus or infected programs.
How it does that?
Identifying suspicious behavior from any computer program which might indicate infection or it tries to match that piece of code to its library or collection of virus codes which are identified by its manufacturer or programmer.In their language these collections or libraries are "VIRUS DEFINATIONS".
Therefore  two approaches are used by antivirus

The suspicious behavior approach, by contrast, doesn't attempt to identify known viruses, but instead monitors the behavior of all programs. If one program tries to write data to an executable program, for example, this is flagged as suspicious behavior and the user is alerted to this, and asked what to do.
 If not this then Your antivirus software relies on virus definitions to detect malware. That’s why it automatically downloads new, updated definition files – once a day or even more often. The definition files contain signatures for viruses and other malware that have been encountered. When an antivirus program scans a file and notices that the file matches a known piece of malware, the antivirus program stops the file from running, putting it into “quarantine.”

                so as this is A growing World.New viruses are generated daily and due to these are identified and add to your antivirus's Library Through daily Updates.
So now whenever antivirus notifies you for a new update,Dont deny as its for your own  security.
So

HEy Friends,

Have you ever opened ReMote of your tv or ever tried to fix a small electronic toy car? If you did you would have noticed a GrEEn rectangular card type circuit having no or less components and many traces or path, lines of metal.

 After seeing such a View and thinking for some time You would reach to conclusion that let some electrician handle, but until coming to decision there would curiosity in your mind that what is it? How it works with such a less no of components.

Its nothing of rocket science.
These are DAa Pcbs- Printed Circuit Boards.Now what these basically are?They are typically thinner and contain finer circuitry .These are made from glass reinforced plastic with copper tracks in places of wires ,Components are placed in this track by first drilling hole and then fixing the components by soldering them.The conductive pathways are printed on board by using computer softwares for designing them and then by ironing or printing the circuit on board.



The circuits which are to be drawn on the board are first simulated in physical word on breadboard
then are designed on computer software,then again simulated in order to remove any problem if left.
The benefit of this circuits are that they are small in size,compact and easy in fabrication and cost efficient too. During designing on software the size of circuit is reduced to a very good extent. And as these have large surface area these can cool down faster and are prone to rough use.

Applications of PCBs, As you all are familiar to applications of these but specifically these are used almost every where like TVs, radios, digital cameras, cellphones,computers,etc. IN computers they serve as foundation to many computer components like Network interface cards,Graphics card.
therefore
MISSION ACCOMPLISHED:ItS SimPle LiFE!!!
