This tutorial will explain you what are the different characteristics of JavaScript 'Strict Mode'. As such, there are two different modes of programming in JavaScript. By default, the simple mode or sometimes known as the sloppy mode is enabled. In this mode, we do not need to follow strict rules while writing the code. On the other hand, the strict mode is also there. This mode enables some strict rules in the environment. Strict mode is not a subset of the sloppy mode but it also has different semantics than normal code. Syntax Strict modes can be ... Read More
A cell is a device which can convert chemical energy into electrical energy. A cell consists of two electrodes and chemical substances inside it. When the cell is connected in a circuit, the chemical reactions take place inside the cell and as a result of these chemical reactions, an electric current flows in the circuit. In this article, we will discuss about galvanic cells and electrolytic cells and how these two types of cells are different from each other.What is a Galvanic Cell?A galvanic cell is an electrochemical cell in which an electric is produced from spontaneous oxidation-reduction reactions.The galvanic ...

Local Area Network (LAN) is used to connect a group of networked devices to allow communication between them, whereas Virtual LAN is used to enhance the performance of multiple LANs.Read through this article to find out more about LAN and VLAN and how they are different from each other.What is LAN?A local area network (LAN) is a network limited to a particular geographic area. A switch, or stack of switches, connects a group of computers and devices using the TCP/IP protocol's private addressing mechanism.Private addresses are distinct from those of other machines on a local network. Routers are used to ... Read More
Both LAN and MAN are computer networks that differ in terms of the geographical area they cover. LANs are private networks limited to a particular geographical area in the range of a few kilometers, while MANs cover a larger area that can span multiple cities and towns.Read through this article to find out the major differences between a LAN and a MAN.Local Area Network (LAN)A Local Area Network is a private network that connects computers and devices within a limited area like an office, a building, or a campus. On a small scale, LANs are used to connect personal computers ... Read More
A circuit breaker is an electrical switching device that can open or close an electric circuit either normally or in case of fault. Therefore, a circuit breaker is one of the major component of an electrical power system or wiring system. A circuit breaker is usually equipped with a control mechanism which enable it to operate automatically in case of abnormal conditions in the circuit. Since the different electrical systems operate at different voltage and current levels. Therefore, according to system voltage and current, there are various types of circuit breakers available such as MCB (Miniature Circuit Breaker), ACB (Air ... Read More
Both servo motor and stepper motor are special electrical machines that can satisfy the basic requirements of a positioning application. Servo motors and stepper motors convert the input electrical energy into angular velocity or movement of the motor shaft. However, there are quite different from each other in the way they operate. In this article, we have highlighted all the differences between servo motor and stepper motor. But, before discussing the differences, let's have some basic information about the servo and stepper motors so that it becomes easier to understand the differences between them. What is a Servo Motor? ... Read More
Both MAC Address and IP Address are used to identify a computer on a network or on the Internet. MAC address is provided by NIC Card's manufacturer and gives the physical address of a computer. IP address is provided by the Internet Service Provider and is called the logical address of a computer connected on a network.Read through this article to find out more about IP address and MAC address and how they are different from each other.What is an IP Address?Every unique instance linked to any computer communication network employing the TCP/IP communication protocols is given an IP address.When ...

An electric motor is an electromechanical energy conversion device which converts the electrical energy input into mechanical energy output in the form of rotation of shaft. Based on the types of electric supply and working, the electric motors are classified in many types such as DC motors, induction motors, synchronous motors, stepper motors, servo motors, and many more. Read through this article to find out the major differences between a servo motor and a DC motor. But, before discussing the differences, let's get a basic overview of servo motors and DC motors. What is a Servo Motor? A type ... Read More
A diode is an electronic device that can perform switching and rectification operation in an electronic circuit. Till date, various types of diodes have been developed with the advancement in technology. In this article, we will discuss about Schottky diode and PN junction diode, and highlight the major differences between them by considering various parameters such as basic definition, circuit symbol, characteristics, applications, etc. What is a PN Junction Diode? A PN junction diode, as its name implies, a semiconductor electronic device which has two layers of oppositely charged semiconductor materials namely P-types and N-type semiconductors These two semiconductor ...

Both RADAR and SONAR are systems used for the detection of objects. Therefore, the primary function of a RADAR and a SONAR is the same, however both use different technologies. Read through this article to find out the major differences between RADAR and SONAR. Let's start with some basics of RADAR and SONAR. What is RADAR? RADAR stands for Radio Detection and Ranging. The RADAR is the technology used for detecting objects such as aircrafts, ships, space-crafts, guided missiles, weather formations, etc. by the use of radio waves. A RADAR measures the distance, angle and radial velocity of an object ... Read More
