What is FTP ?

 FTP
-FTP stands for file transfer protocol.
-The Transport protocol of FTP is TCP     because it requires reliability.
-The port number of FTP is 20/21.Port 20   performs the task of forwarding and   transferring of data and port 21 performs   the task of transmitting of commands.
-It is a standard internet protocol provided   by TCP/IP for transmitting the file(which     may contain any kind of digital   information,such as text document,   movie ,image etc.) from one device to   another.
-It is mainly used for transferring the web   page files from their creater to the   computer that acts as a server for other   computer on internet and it is also used   for downloading the files to computer   from other servers.
-The main competitor for FTP is Http and   now sites runs Http servers instead of   FTP servers.Because Http server is more   efficient than the FTP server.
Advantages of FTP
-FTP is more secure to use because if we   want to access FTP server then we need   to log in with user name and password to   access the FTP server .For this reason   FTP is secure .
-The another advantages of FTP is   speed.The FTP is one of the fastest way   to   transfer the file from one computer to   another.

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.

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 ...
