A Bipolar Junction Transistor (BJT) is a three-terminal device which consists of two pn-junctions formed by sandwiching either p-type or n-type semiconductor material between a pair of opposite type semiconductors.The primary function of BJT is to increase the strength of a weak signal, i.e., it acts as an amplifier. A BJT can also be used as a solid state switch in electronic circuits.Types of BJTThere are two types of BJTs −NPN TransistorPNP TransistorIn this article, we will discuss in detail the working principle of both these types of BJTs.NPN TransistorAn npn-transistor is composed of two n-type semiconductor materials which are ...

To get the Windows System uptime with PowerShell, we can use the CIM Instance method with class name Win32_OperatingSystem. Once you use the mentioned class there is a property called LastBootupTime which shows the date when the computer is last rebooted.ExampleGet-CimInstance -ClassName Win32_OperatingSystem | Select LastBootUpTimeOutputLastBootUpTime -------------- 9/29/2020 8:12:08 AMIf we check the datatype of the above output, it should be DateTime because of the output format.(Get-CimInstance -ClassName Win32_OperatingSystem).LastBootUpTime.Gettype()OutputIsPublic IsSerial Name BaseType -------- -------- ---- -------- True True DateTime System.ValueTypeWe need now the uptime of the system in Days-Hours-Minutes format. So we will compare ... Read More
Binary is the simplest kind of number system that uses only two digits of 0 and 1 (i.e. value of base 2). Since digital electronics have only these two states (either 0 or 1), so binary number is most preferred in modern computer engineer, networking and communication specialists, and other professionals. Whereas Octal number is one of the number systems which has value is 10 and it has only 8 symbols: 0, 1, 2, 3, 4, 5, 6, and 7. Conversion from Binary to Octal number system Octal number system provides convenient way of converting large binary numbers into more ... Read More
To disable the default scroll anchoring provided by web browsers, we can use the overflow-anchor property. To disable scroll anchoring, set the overflow-anchor property to none − body { overflow-anchor: none; } To enable the scroll anchoring, set the value to auto that is also the default value. However, scroll anchoring behavior is enabled by default in any web browser. Disable Scroll Anchoring Let us see the example to disable scroll anchoring − Example body { ... Read More
