When a client creates the web or another computer network which is external to their current position, the messages are transmitted by the transmission media web. This method of shifting the data from one computer network to another network is called data switching.Switches can be called as an advanced form ... Read More

The Wavelength Division Multiplexing (WDM) is done only in fiber optic channels. In WDM, several light waves from multiple sources are connected by using a prism to form a composite light signal sent across the medium.At the receiver end, the hybrid light is broken down into different light waves, and ...

The electromagnetic waves having frequencies from 300 GHz to 400 THz (wavelengths from 1mm to 770 nm) are referred to as infrared (IR) waves. IR uses line-of-sight propagation.Infrared light is a transmission channel whose features are necessarily different from those of the radio frequencies. A fundamental property of infrared light ...

OSI represents Open System Interconnection. It was produced by the International Organization for Standardization (ISO) located in Geneva, Switzerland, and the consultative committee for international Telephone and Telegraph (CCITT).OSI was created to develop a frequent standard of network structure throughout the globe. It supports a general idea of inter-process communication so ... Read More

The presentation layer changes the data from an application layer into the device native internal mathematical structure and encodes communicated information into a displayable output format.It executes the code changes, document compressions, security encryption, etc. It also defines the data as per the software/hardware environment of the hub. For instance, ... Read More

The session layer supports establishing, controlling, and eliminating a session or dialogue between the two end frameworks. It generates the session, handles the packets sent back and forth during the session and removes the session. The dialogue type/session type is also defined through half-duplex or full-duplex.The session layer also supports ... Read More

Physical layer is the shortest layer in the model. This layer is feasible for initiating, preserving, and deactivating a physical circuit between two end frameworks.The Physical Layer is vital for transmitting bits from one device to another device. It can change the series of bits into electric signals, light signals, ... Read More

OSI represents Open System Interconnection. The OSI reference model is a seven-layered architecture and is created in a hugely structured method. Each layer in the model has specific sets of procedures, functions, and protocols. One layer can communicate with an adjacent layer by using its interface.OSI model was advanced by ... Read More

To separate a particular portion from the image, we have to locate the area first. Then we have to copy that area from the main image to another matrix. This is how the ROI in OpenCV works.In this example, two matrices have been declared at the beginning. After that, an ... Read More

We have declared three variables named-'blue_Channel', 'green_channel' and 'red_channel'. The goals of these variables is to save the pixel values. We have used these variables inside the 'for loops'. Then we declared a matrix named 'color_Image_Matrix'.The syntax of this method is:blue_Channel = color_image_Matrix.at(i, j)[0];We used a BGR image. It has ... Read More
