UPS(Un-interrupted Power Supply)

An Uninterruptible Power Supply is a device that sits between a power supply (e.g. a wall outlet) and a device (e.g. a computer) to prevent undesired features of the power source (outages, sags, surges, bad harmonics, etc.) from affecting the performance of the device.

(UPS) play two important roles in power protection:

1) Providing a source of standby power in the event of a mains failure.

2) conditioning mains electricity to remove power problems such as sags, surges, brownouts and fluctuations that can damage equipment, cause computers to  fail or crash and lead to data loss or corruption.

A UPS generally protects a computer against four different power problems:

                              

                               Voltage surges and spikes - Times when the voltage on the line is greater than it should be

                               Voltage sags - Times when the voltage on the line is less than it should be

                               Total power failure - Times when a line goes down or a fuse blows somewhere on the grid or in the building

                               Frequency differences - Times when the power is oscillating at something other than 60 Hertz

Different types of UPS

There are three conventional types of uninterruptible power supply:

• Online
• Line Interactive
• Offline

How to Test the Working of your Antivirus – EICAR Test

The process is called EICAR test which will work on any antivirus and was developed by European Institute of Computer Antivirus Research. This process can be used by people, companies and antivirus programmers to test the proper functioning of the antivirus/antimalware software without having to deal with the real computer virus which can cause damage to the computer. Here is a step-by-step procedure to test your antivirus.
1. Open a notepad (New Text Document.TXT) and copy the following code exactly onto it, and save the notepad.

EICAR Test code
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

2. Rename the file from New Text Document.TXT to myfile.com
3. Now run the antivirus scan on this myfile.com file.
If the antivirus is functioning properly on your computer, then it should generate a warning and immediately delete the file upon scanning. Otherwise you may have to re-install your antivirus.

NOTE: Most antivirus will pop-out a warning message in the Step-1 itself

You can also place the myfile.com file in a ZIP or RAR file and run a scan on it so as to ensure whether your antivirus can detect the test string in the compressed archive. Any antivirus when scanning this file will respond exactly as it will do for a genuine virus/malicious code. This test will cause no damage to your computer even though the antivirus will flag it as a malicious script. Hence it is the safest method to test the proper functioning of any antivirus.
