Acid Rain - Definition, Causes, Effects of Acid Rain What is Acid Rain? Acid rain, as the name suggests, can be said as the precipitation of acid in the form of rain in the simplest way. When atmospheric pollutants like nitrogen and sulphur oxides react with rainwater and fall with the rain, this results in acid rain. (Credits: Google Images) Definition of Acid Rain Acid rain is made up of highly acidic water droplets due to emissions into the air, more specifically disproportionate levels of sulphur and nitrogen emitted by vehicles and manufacturing processes. It is often called acid rain as this concept contains many types of acid precipitation. Acid deposition takes place in two ways: wet and dry. Wet deposition is any form of precipitation that removes acids from the atmosphere and places them on the earth's surface. In the absence of precipitation, the dry deposition of polluting particles and gases adheres to the ground through dust and smoke. Causes of Acid Rain The causes o

Networking Interview Questions and Answers 1) What is a Network? Answer: The network is defined as a set of devices connected to each other through a physical transmission medium. For example, a computer network is a group of computers connected to each other to communicate and share information and resources such as hardware, data, and software. In a network, nodes are used to connect two or more networks. 2) What is a Node? Answer: Two or more computers are directly connected by fiber optics or any other cable. A node is a point where a connection is established. It is a network component used to send, receive, and forward electronic information. A device connected to a network is also called a Node. Let us consider that in a network there are 2 computers, 2 printers, and a server connected, then we can say that there are five nodes in the network. 3) What is Network Topology? Answer:  Network topology is a physical layout of the computer network and defines how computers, devices,

Mathematical Symbols (Source: Google Images) Basic mathematical symbols with name, meaning, and examples : The basic mathematical symbols used in Mathematics help us to work with mathematical concepts in a theoretical way. In simple words, without symbols, we cannot do mathematics. Mathematical signs and symbols are considered representative of value. The basic symbols in mathematics are used to express mathematical thoughts.  The relationship between sign and value refers to the fundamental need of mathematics. With the help of symbols, certain concepts and ideas are clearly explained. Here is a list of commonly used math symbols with names and meanings. In addition, an example is provided to understand the use of mathematical symbols. Symbol Symbol Name in Maths Math Symbols Meaning Example ≠ not equal sign inequality 10 ≠ 6 = equal sign equality 3 = 1 + 2 < strict inequality less than 7 < 10 > strict inequality greater than 6 > 2 ≤ inequality less than or equal to x ≤ y,
