Difference between CD-ROM and Magnetic Disks
CD-ROM and Magnetic disks are the types of permanent (non-volatile) storage media used in computers and many other digital devices to store data and information in digital form. In this article, we will discuss the important differences between CD-ROM and magnetic disks. The most fundamental difference between CD-ROM and magnetic disks is that CD-ROM is a type of optical storage device, whereas magnetic disks, as the name implies, be the type of magnetic storage device. Before discussing the differences between CD-ROM and magnetic disks, let us first know a bit about them individually. What is a CD-ROM? CD-ROM stands for ...
Read MoreASCII vs. UNICODE
ASCII and UNICODE are the two most extensively used character encoding schemes in computer systems. The most basic difference between ASCII and UNICODE is that ASCII is used to represent text in form of symbols, numbers, and character, whereas UNICODE is used to exchange, process, and store text data in any language. What is ASCII? ASCII stands for American Standard Code for Information Interchange. It is a standard developed for character encoding in electronic communication. ASCII was first published in 1963. In computers and other electronic systems, it is used for representing text as symbols, characters, and numbers. In ASCII, ...
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 ...
