Which language is better....PHP or Node Js?

hey ..I am back with another interesting question....which language is better php or node js.
for understanding this theory you have to first understand the concept of webserver.
What is webserver.....???
webserver is a system which uses https request to perform operations.
let us consider about this ..suppose I have a website like allnonecyberteam.com.If user request any page then first webserver go to open file and then response back......now I think  its clear what is webserver.
now lets consider php and node js.
how does these works.
first consider about php.
php requset pages synchronus type,means it first go to server and open files and then response back
and after that it prepare to handle next requset.
php is slower than node js.
why its slower than node js we will talk about it after understanding concept of node js.
php works on apache web server .php also can run on IIS web server in case of windows machine.
Php is much simpler than node js.

Now consider about Node js.
node js has its own environment.
it uses javascript in backend side so it create its own server.NPM(Node package manager) doesnt need any webserver.
so basically both technology are good but if which language you want to use its depend on your project nature.
if you need centralized server and portablity then use php otherwise if you want speed,real time data and same language across the stack then use node js.
thank you......

NMAP and ZenMAP

NMAP and ZenMAP are useful tools for the scanning phase of Ethical Hacking in Kali Linux. NMAP and ZenMAP are practically the same tool, however NMAP uses command line while ZenMAP has a GUI. NMAP is a free utility tool for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. NMAP uses raw IP packets in novel ways to determine which hosts are available on the network, what services (application name and version) those hosts are offering, which operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, etc. Now, let’s go step by step and learn how to use NMAP and ZenMAP. Step 1 − To open, go to Applications → 01-Information Gathering → nmap or zenmap. Step 2 − The next step is to detect the OS type/version of the target host. Based on the help indicat...

ethics and haking 1

1. A HISTORY OF HACKING Hacking has been around for more than a century. In the 1870s, several teenagers were flung off the country's brand new phone system by enraged authorities. Here's a peek at how busy hackers have been in the past 35 years. 1.1. Early 1960s University facilities with huge mainframe computers, like MIT's artificial intelligence lab, become staging grounds for hackers. At first, "hacker" was a positive term for a person with a mastery of computers who could push programs beyond what they were designed to do. 1.2. Early 1970s John Draper makes a long-distance call for free by blowing a precise tone into a telephone that tells the phone system to open a line. Draper discovered the whistle as a give-away in a box of children's cereal. Draper, who later earns the handle "Captain Crunch," is arrested repeatedly for phone tampering throughout the 1970s. John Draper Yippie social movement starts YIPL/TAP (Youth Internatio...
