Sockets
allow you to exchange information between processes on the same machine or across a network
, distribute work to the most efficient machine, and they easily allow access to centralized data. Socket application program interfaces
Where is socket used?
Sockets are commonly used
for client and server interaction
. Typical system configuration places the server on one machine, with the clients on other machines. The clients connect to the server, exchange information, and then disconnect. A socket has a typical flow of events.
What is socket programming and why?
Socket programming is
a way of connecting two nodes on a network to communicate with each other
. One socket(node) listens on a particular port at an IP, while other socket reaches out to the other to form a connection. Server forms the listener socket while client reaches out to the server.
Why are sockets important in DCN?
A socket is
one endpoint of a two way communication link between two programs running on the network
. The socket mechanism provides a means of inter-process communication (IPC) by establishing named contact points between which the communication take place.
What are the two types of sockets?
- Stream sockets allow processes to communicate using TCP. A stream socket provides bidirectional, reliable, sequenced, and unduplicated flow of data with no record boundaries. …
- Datagram sockets allow processes to use UDP to communicate. …
- Raw sockets provide access to ICMP.
What is the difference between port and socket?
| Socket Port | It is used to identify both a machine and a service within the machine. The same port number can be used in different computer running on same software. |

What are the advantages of socket programming?
Sockets are
flexible and sufficient
. Efficient socket based programming can be easily implemented for general communications. It cause low network traffic. Socket based communications allows only to send packets of raw data between applications.
What are the applications of socket programming?
Sockets allow
you to exchange information between processes on the same machine or across a network
, distribute work to the most efficient machine, and they easily allow access to centralized data. Socket application program interfaces (APIs) are the network standard for TCP/IP.
Is socket programming still used?
Most current network programming, however,
is done either using sockets directly
, or using various other layers on top of sockets (e.g., quite a lot is done over HTTP, which is normally implemented with TCP over sockets).
What type of socket is created?
A socket is
created with no name
. A remote process has no way to refer to a socket until an address is bound to the socket. Processes that communicate are connected through addresses. In the Internet family, a connection is composed of local and remote addresses and local and remote ports.
How many different types of sockets are there?
There are
two main types
of sockets: impact and hand.
Which is not true for socket?
2) it is communication end point. 3) used to send and receive data. 4) always connection oriented.
What is the difference between a ratchet and a socket?
A ratchet is a handle that snaps into
one
end of a socket by means of a square-drive connector. The other end of the socket fits over a fastener. A mechanism in the ratchet allows the handle to engage and tighten the fastener when you swing it in a clockwise direction and turn freely when you swing it counterclockwise.
How many sockets are in a complete set?
So for 1 size, you would need
12 sockets
. Example: 9/16 socket, there would be a 6 point, 12 point, then a 6 and 12 deep. That’s 4, multiplied by the 3 drive sizes.
How do I know my socket size?
- Turn on the digital caliper and set it to read in inches, not millimeters. …
- Close the caliper jaws until each jaw rests on one flat side of the nut on opposite sides.
- Check the caliper display. …
- Turn on the digital caliper and set it to read in millimeters, not inches.
How many sockets can a server have?
For most socket interfaces, the maximum number of sockets allowed per each connection between an application and the TCP/IP sockets interface is
65535
.
