Gateway: Gateway is a medium, which acts as a bridge or bridge between two networks so that many computers can exchange data together. That is, the device used to connect different types of networks is the gateway. It translates the protocol. It works on layer 7 of the OSI model. Switch: Network switch and network hub are the main pillars of computer networking. In networking, a switch is a device that performs filtering and packet forwarding when exchanging data packets between different parts of a local area network. The switch and SI layer operate at the data link layer. But sometimes it also works at network layer. A local area network (LAN) that uses switches to communicate between its different parts is called a switched LAN. Switches are the network layer that additionally processes data (Layer 3) and are often referred to above as Layer 3 switches. The first Ethernet switch was introduced in 1990. Functions of switches: Network switches are switches connected to most modern E...

Router: A router is a computer networking device that determines which way data will go through different networks. It is used to connect one network to another network and to route data packets from network to network. In this case the device is called a router. Routers break up broadcast domains in such a way that all devices under a network segment can read and process broadcasts sent for that network segment. A router connects two or more logical subnets. Its network hub does not perform any routing. Rather, it forwards every packet it receives on a network line to other network lines. Routers operate in two different planes: Control plane: Where the router selects the appropriate outgoing interface, which sends specific packets to specific destinations. Forwarding plane: which determines the forwarding of packets received by a logical interface. Initially routers were known as gateways. It was first conceived by the International Networking Group (INWG), an international computer...

Data transmission mode The mode of data movement depends on the direction of data movement. Data transmission modes are generally divided into three categories; namely- (i) Simplex mode or unidirectional mode, (ii) Half-duplex mode or meaning duplex mode, (iii) Full-duplex mode or pre-duplex mode or duplex mode. Simplex : The data transmission mode in which data is transmitted only in one direction is called simplex transmission mode. In this method data can be transmitted only in one direction. That is, the sending computer can send data to the receiving computer. But the receiving computer can never send the data to the sending computer. The first computer can only send data to the second computer. But the second computer cannot send data to the first computer. Half Duplex Mode : At this speed data can be sent in both directions but not simultaneously. When the sending computer sends data to the receiving computer, the receiving computer only receives the data. But the sender cannot ...

Data communication Data communication is the process of transferring any data from one end to another end or from one computer to another computer or from one device to another device or from one person to another. Here, data refers to the electrical form of information stored in a computer. Communicating devices consist of hardware and software for data communication. The performance of data communication system mainly depends on three characteristics. For example: (i) Delivery: The system must deliver the data to the right end. (ii) Accuracy: The system must deliver data accurately. (iii) Timelines: The system must deliver timely data. Main element of data communication and work: A data communication system usually consists of five elements; namely-- (i) Message,  (ii) Source and sender of data,  (iii) Receiver of data,  (iv) Medium,  (v) Protocol (1) Message: The message is what is sent. Messages can be of various types, such as text, image, audio/sound, video etc...

Generation of programming languages In the early days of programming languages, i.e., writing programs for computers to solve problems using machine language was cumbersome, time-consuming, and limited in scope. But today's computers have artificial intelligence. That is, people do not have to memorize thousands of instructions or commands to solve computer problems, they do not have to follow specific rules (grammar). Currently, computers can also recognize human speech and solve problems according to the instructions. In addition to computers, there have been various types of development, contraction, modification and expansion of programming languages ​​at different times or stages in the field of such improvement and development of programming languages. The advent of today's simple, efficient and universal programming languages ​​has basically crossed 5 generations. The stages are— 1st generation: Machine language is called 1st generation language. Representing Binary 0 o...

Introduction to programming languages A set of instructions used by a computer to solve a problem is called a program. The language used to write programs is called programming language. Initially machine language was used as a programming language but later assembly language and high level languages came into vogue. C is such a procedural programming language. Concept of Program: A set of instructions used by a computer to solve any mathematical or logical problem is called a program. The process of writing programs is called programming. Any complex problem can be solved easily with proper programming. The number of instructions used in program writing depends on the type of problem. Programming Language :  Computer is a powerful device. It is suitable for complex tasks. It is not possible to do any work with it unless it is properly told what to do. So what needs to be done must be explained to the computer in such a way that it can understand it and carry it out to the letter. ...

Basic concepts of programming Computer programs and programming Computer program : Computer program is a series of instructions given to the computer, through which almost all the problems of real life can be solved by using computer hardware and software.

What is Scalping: Scalping is the trade that starts with two or three pips and is opened for 15-20 pips. And the trade opened in this short time is called scalping. Those who do scalping are called scalpers. Scalping trades do not have any fixed time limit but stop loss and take profit are essential. The correct timeframe for scalping is 5,10,15,30,45 minute timeframe. When you go scalping on the 15 minute time frame you can see where the market is going on the h1,h4,d1 time frame. If the 5 minute timeframe is a buy position and the 15 minute timeframe is a buy position then you can enter scalping. And if these two charts give two types of signals, then you should not do scalping. Never scalping against H1,H4 timeframes. If you go against the H1, H4 timeframe, you will float in the forex market or currency ocean. You can be a gainer in the forex market if you go against the trend (market direction). There is no better timeframe for scalping than the 15 minute timeframe. When you see H...

In this organization, computers and devices send signals to each other's nodes through buses. At this time other computers and terminals connected to the bus line examine the signal and only the ...

| Nano Technology   The word Nano is derived from the Greek word Nanos. Which means a dwarf or a miniature human or other creature with magical powers. The technology or technology that is used to convert molecules or atoms into nanoparticles or molecules or atoms is called nanotechnology. In detail, when molecules or atoms are changed to a nano-meter scale using a special technology or device to enhance the performance of an object, that technology is called nanotechnology. Nano is basically a unit of measurement. Which is equal to one billionth of a meter. For ease of understanding, the hair on our head is 80,000 nanometers wide. The atom, the smallest unit of matter, is one-tenth of a nanometer. The DNA contained in living cells is 2 nanometers wide. Molecules or atoms are a few nanometers in length, so the molecular-atomic measurement scale is called the nanoscale. The principle of this technology is that everything will be made at the nanoscale. The main advantage of this...

Market order: There are two types of market order. namely- 1. Market Execution Order 2. Market Pending Orders 1. Market Execution Order: When buying/selling a pair at the current market price, it is called a market execution order. That is, when we sell directly at the price, it is a market execution order. 2. Market Pending Order: If you want to buy/sell in the future at a price other than the current price, it is a market pending order. ** Pending order means that even if you are not in the market, your pending order will be active if the market goes to the rate at which you place a buy/sell order in the market. That is, pending order is the name of determining a certain rate before going to the market. There are four types of market pending orders. Namely – 1. Buy Limit 2. Sell Limit 3. Buy Stop 4. Sell Stop 1. Buy Limit: Buy limit is lower than the current price if you want to buy then you have to give Buy limit pending order. In case of buy limit pending order, you can never place...

What is trend retracement or correction : When the market price moves against the main trend, it is usually called trend retrestment or correction. When a small movement is made against the uptrend, it is called a retest or correction. A sudden downtrend is called a retest or correction. This movement of the market against the uptrend is a market correction or trend retracement. Essentially, market movement against the main trend is called a retracement. Same definition for down trend. If there are more buyers than sellers, the market goes down. Again, when there are more buyers than sellers, the market starts to rise. This is one of the reasons for retrestment or correction. Sellers cannot hold the market against the trend for long. For this, the market makes small movements. And these small movements are retrestment or correction, when the presence of buyers in this market is more, then they move against the trend, and when it is seen that the presence of sellers is more, then the ma...

Trade lock in Forex: The trade lock is to set the stop loss to some profit from the entry point. The entry point is the trade point. That is, the trade line is the entry point. Trade lock is when any trade goes into profit, so that those trades do not close again at a loss, setting a stop loss at some profit from the entry point is called a trade lock. Trailing Stop : A trailing stop will automatically move your stop loss. Your stop loss will automatically move through the trailing stop. That is, if you use a trailing stop, whenever your trade goes into profit, as soon as you go into profit, the stop loss will be set as many pips below the current market price as you use the trailing stop. Tailing stop is 10 pips if you give 100 pips. And giving 200 pips sets 20 pips. When using a trailing stop, if the market goes up, the stop loss will also go up. But a trailing stop will not work if the trade is not in profit. Moreover, Teling Stop will not work if the device does not have an intern...
