Lesson: All About Sockets A socket is one end-point of a two-way communication link between two programs running on the network. Socket classes are used to represent the connection between a client program and a server program. The java.net package provides two classes--Socket and ServerSocket--that implement the client side of the connection and the server side of the connection, respectively. Reading from and Writing to a Socket. This page contains a small example that illustrates how a client program can read from and write to a socket. Writing a Client/Server Pair

Asynchronous Java NIO for dummies Asynchronous Java NIO for dummies. This article explains the fundamentals of Java NIO asynchronous socket programming with a very simple server/client example. Java NIO uses multiplexing to server multiple clients from the same thread. Before NIO, a server had to open a thread for each client. At first NIO is very intimidating and a bit confusing. I hope to make this as simple as possible for your understanding.

Linux Port numbers Socket is combination of software Port and IP address. Port numbers can vary from 0 to 65535, so total we can get 65536 ports. This is because limitation in TCP/IP stack where the port number field is just 16bit size. So we get only 2^16(2 to the power of 16) ports which are equal to 65536 available ports.

What is the JAXB2 Maven Plugin? What is the JAXB2 Maven Plugin? This plugin uses the Java API for XML Binding (JAXB), version 2+, to generate Java classes from XML Schemas (and optionally binding files) and to create XML Schemas from annotated Java classes. The plugin delegates most of its work to either of the two JDK-supplied tools XJC and Schemagen, through its JAXB implementation dependencies.

- Sockets: Process Identification. What this all means is that the overall identification of an application process actually uses the combination of the IP address of the host it runs on—or the network interface over which it is talking, to be more precise—and the port number which has been assigned to it. This combined address is called a socket.

Buyer's Guide: Buying the Fastest Processor The socket describes the physical receptacle on a computer’s motherboard that accepts the chip. Note that not all chips made for a given socket work with all motherboards that have that socket. In some cases, the processor may also require a specific supporting chipset on the motherboard, or a BIOS update.

What is the difference between port and socket in Internet terminology? Port: In simple language, Port is a number used by a particular software to identify its data coming from internet. Each software like, skype, chrome, youtube has its own port number and thats how skype or youtube knows which internet data is for itself. Socket: IP address and Port  together is called Socket. It is used by another computer to send data to one particular computer's particular software. IP address is used to identify the computer and Port is to identify the software such as IE, Chrome, Skype etc.

Java IO: Exception Handling Java IO Exception Handling From Java 7. From Java 7 on and forward Java contains a new exception handling mechanism called try with resources. This exception handling mechanism is especially targeted at handling exception handling when you are using resources that need to be closed properly after use, like InputStream, OutputStream etc. You can read more about it in my tutorial about Try With Resources in Java 7. Next: Java IO: InputStream.

- A socket address is the triple: {protocol, local-address, local-process} where the local process is identified by a port number. In the TCP/IP suite, for example: {tcp, 193.44.234.3, 12345}. A conversation is the communication link between two processes thus depicting an association between two.
