What happens if 2 programs use the same port?
Yes. Multiple listening TCP sockets, all bound to the same port, can co-exist, provided they are all bound to different local IP addresses. Clients can connect to whichever one they need to.
Do different browsers use different ports?
Browsers open tabs in separate threads (and new ones even in separate processes for security and reliability reasons), and use separate ports on the client side. So yes, the answer is both threads and ports.
Can you have two browsers one computer?
Yes. All browsers act independently, allowing you to run multiple browsers at the same time.
Can two processes use the same port number?
The short answer is “no, not on the same host.” The only time it would make sense to have multiple applications listening on the same port is if a single application were not sufficient to service all the incoming requests. …
Can multiple threads listening on same port?
Multiple servers (processes or threads) can bind to the same port if they each set the option as follows: With TCP sockets, it allows multiple listening sockets—normally each in a different thread—to be bound to the same port. Each thread can then accept incoming connections on the port by calling accept().
How do I connect to a specific port in my browser?
If the website is already talking on a different port, you can just use the colon syntax to reference another port (eg: http://server.com:1234 for port 1234).
Can both browsers connect to www Google com using the same client port?
So yes, the answer is both threads and ports. They always use the same remote port unless you physically specify otherwise (for example, connecting to a website using https:// instead of http:// uses a separate port because that’s how that protocol was made).
Can multiple applications use port 80?
No. Only one program can open a socket on one port on one IP address at one time. But you can create an IP alias on a network card – a machine can have more than one IP address, even on the same card. Then each program could listen to broadcasts on the same port on the same LAN, but on different addresses.
Can multiple servers bind to same port?
Multiple servers (processes or threads) can bind to the same port if they each set the option as follows: With TCP sockets, it allows multiple listening sockets—normally each in a different thread—to be bound to the same port.
How does a browser connect to a server from another port?
In order to communicate your browser would open a local port (usually something big like ~5000, and that doesn’t matter as long as its unique) and connect to the server on usually port 80 (the one the server is listening on). If your computer didn’t know the remote port it couldn’t connect, but its standard to use 80 for HTTP, for example.
How multiple clients can connect to the same port on server?
Multiple clients can connect to the same port (say 80) on the server because on the server side, after creating a socket and binding (setting local IP and port) listen is called on the socket which tells the OS to accept incoming connections.
Can I have two browsers on my computer at once?
Like other programs, you can have as many on your computer as you like and even have them running at the same time with no conflicts. Below is a listing of the top alternative browsers you may want to consider trying. Alternative browsers include: Mozilla Firefox. Google Chrome. Opera. Safari. Internet Explorer.
What happens when a remote computer connects to port 80?
Once a remote computer connects, then he would hog the port 80 to port 80 connection, and no one else could connect. 1.) On a server, a process is listening on a port.
