Difference between Hub and Switch

Hub is a networking device which operates on physical layer of the OSI(open system interconnection) model whereas switch is also a networking device but it operates on data link layer of the OSI model .Hub is purely hardware but switch is a device which is the combination of both software and hardware.Hub supports broadcast transmission whereas switch supports Unicast, multicast and broardcast transmission .Hub is having single collision domain whereas Every port of Switch is separate collision domain.Transmission mode of hub is half-duplex whereas transmission mode of switch is full-duplex.Hub can do only forwarding whereas Switch can be able to do both forwarding and filtering.Hub can't store MAC (media access control) address where as switch stores MAC address.

TCP/IP Model

TCP/IP stands for Transmission control protocol/Internet protocol.TCP is a transport layer protocol and IP is a network layer protocol .TCP and IP both are different protocol but by the help of these two protocol ,TCP/IP model was developed.TCP/IP model defines how data is transferred from one computer to another.When two devices communicates with each other through the help of internet ,it is possible only for TCP/IP model .The TCP/IP model consists of 4 layers.These are :- (1) Application layer:- -This layer performs the function of the top three layer of the OSI model,i.e.Application layer , presentation layer and session layer . -The application layer is the top-most layer of the TCP/IP model. -The application layer provides the user with the interface to communication. -There are several protocols used by the application layer for interaction such as:FTP,HTTP, SMTP,DNS,TELNET etc. -The application layer sends data to transpo...

MAC Address

MAC stands for media access control. MAC address is also known as physical address or hardware address or BIA(burnt-in-address).BIA is generally written in Cisco router switches.physical address is generally written in laptop/pc.MAC address is generally written in Mobile. MAC address is globally unic.The MAC address of a device is different from other devices.Many people are thinking there is only one mac address of a device but it is actually wrong ,Because there is no mac address of a laptop .There is a Mac address of your NIC(network interface controller) ,which is connected to your laptop . (NIC) If you change your NIC,then the Mac address of your laptop will be changed.NIC is a separate hardware component present in your computer used to connect with the network (home network or internet).There are so many ways that you can connect your laptop with the network like...

Linear Regression in Power BI

Linear Regression is Predictive model used for finding the linear relationship between a dependent and one or more independent variables. In regression the dependent variable has to be continuous numerical (not categorical like Green, Yellow etc). In Simple linear regression, we have one independent variable and one dependent variable. It is also known as Univariate linear regression, as there is only one independent variable. In Multiple linear regressions, we have more than one independent variable and one dependent variable. It is also known as multivariate linear regression, as there is more than one independent variable. Now our goal is to predict the home price by using the Simple Linear Regression. (Name of the above table is SimpleLinearRegression ) In this table we have the prices of home based on the Area of that home. Here we have to predict the Price based on the given Area. As we are predicting the price based on the area. So, Price is the dependent variable and ...
