which is operating system more demand in it filed future,Microsoft or Linux ? Pls suggestion i am very confuse.

How long u can make away ur computers from viruses? How many Anti-virus u will install for protecting ur computer? As Antivirus get installed in ur computer ur computer get slow. Am i right? Do u think that All the servers might be running on Windows? if so how much speed u will get in the network s

Both are good demand , Microsoft OS is most conman use , but in some security purpose for big project , or host some big project LINUX is also used , if you get LINUX certificate then it have good value

both are required
