Booting and Dual Booting of Operating System
When a computer or any other computing device is in the powerless state, its operating system remains stored in the secondary storage like Hard Disk or SSD. But, when the computer is started, the operating system must be present in the main memory or RAM of the system. When a computer system is started, there is a mechanism in the system which loads the operating system from the secondary storage into the main memory or RAM of the system. This is called Booting process of the system. There are two types of booting depending on the number of operating systems ...
Read MoreAdvantages and Disadvantages of Windows Operating System
Windows Operating System Windows Operating System is a type of operating system based on Graphical User Interface (GUI). It is called a graphical user interface because it create an interface (communication screen) between user and machine by using graphical elements like icons, pictures, colors, etc. The Windows operating system was developed by Microsoft Corporation, an American Multinational technology company founded by Bill Gates and Paul Allen. Windows operating system is one of the most popular computer operating systems in the world. The primary reason behind its global popularity is its very user-friendly interface. Windows operating system also provides multitasking capabilities, ...
Read MoreImplementation of a Logic Function using OR and AND Gates
We can realize or implement a Boolean expression or a logic function as hardware using logic gates. The easiest method of implementing a logic function as hardware using logic gates is to start with the output and moves towards the inputs. The implementation of a logic function with the help of logic gates involves connecting different logic gates in a specific manner. In this article, we shall confine our attention to implementing a logic function using the OR and AND gates only. Let's start the article with a brief introduction of OR and AND gates. What is an OR Gate? ...
Read MoreImplementation of Boolean Functions using Logic Gates
A Boolean function is a logical expression that returns a Boolean value, which is a value that is either TRUE or FALSE. In digital electronic circuits, the logic gates are used to implement a conditional or logical or Boolean expressions. A logic gate is a digital circuit that performs a specific logical operation on one or more input variables or signals and generates an output signal. The output of a logic gate is determined by its logical function, which is based on Boolean algebra. In digital electronics, there are several types of logic gates available such as AND gate, OR ...
Read MoreDifference between Electric Field and Magnetic Field
There is a property of space which is caused by the motion of the electric charge, is known as electromagnetic field. There are two component of an electromagnetic field viz. −Electric fieldMagnetic fieldA stationary electric charge produces only an electric field in the surrounding space. If the electric charge is moving, then it also produces a magnetic field. The electric field and magnetic field occupy different planes relative to the cause of the electromagnetic field, i.e., moving charge.Therefore, one of the major difference between electric field and the magnetic field is that the electric field produces around a static electric ...
Read MoreThe Realization of Logic Functions Using NAND Gates
A logic function is a basically a Boolean expression that returns a Boolean value, which is a value that is either TRUE or FALSE. The NAND gate is a universal logic gate, thus it can be used to implement any type of logic function. Read this tutorial to learn how you can realize different logic functions using NAND gates. Let's start with a basic introduction of the NAND gates What is a NAND Gate? A NAND Gate is a type of universal logic gate that one can use to realize any kind logical expression or any other type of logic ...
Read MorePositional Number System
A number is a method used for representing an arithmetic value, measure, or count, of a physical quantity. A number system is defined as a method of naming and representing numbers. The concept of number system helps in defining the rules associated with the numbers and different operations on numbers. A number system is determined with the help of its radix or base. The radix or base of a number system is nothing but the total number of symbols used in the number system for representing the different numbers. For example, in the decimal number system, there are 10 ...
Read MoreBuild an Inverter with a Transistor
In this tutorial, we will discuss the realization of an inverter (NOT gate) with a transistor. But before that let's have a look into the basics of inverter or NOT gate. What is an Inverter (NOT Gate)? An inverter is a single input and single output logic gate that toggles or inverts the logic level (or state) of a single to the opposite state or logic level. The inverter is also known as NOT gate. When a low signal (logic 0) is applied to an inverter, it transforms it to a high signal (logic 1). If a high signal (logic ...
Read MorePositive and Negative Logic in Digital Electronics
In digital electronics, a logic or logic function is one that follows the rules that governs a logical statement. Logics are implemented by using switching networks, where a switching network is one that is designed by interconnecting a finite number of switches. Example − Let "𝒚" is a logic function, then it may be expressed as, $$\mathrm{Y = f\left ( x_{i} \right ) }$$ Where, xi represents the inputs to the logic network or switching network, and y is the output of the network. There is another term associated with the logic function that is the truth table. The truth ...
Read MoreWhat is Voltage Regulator 7805 – Internal Block Diagram and Applications
In this article, we will discuss the definition, internal block diagram, circuit configuration, and applications of voltage regulator 7805 IC. Let’s begin with the basic introduction of voltage regulator. A voltage regulator is an essential element of power supplies used in several electrical and electronic devices such as computers, amplifier, automobile alternator, mobile chargers, etc. A voltage regulator is basically an electronic circuit that generates a regulated voltage of fixed value from an unregulated fluctuating voltage. A voltage regulator is required in a circuit because all voltage sources cannot provide a steady voltage due to change in the load current ...
