What is Socket Programming ?  A   socket   is a communications connection point (endpoint) that you can name and address in a network. Socket programming shows how to use socket APIs to establish communication links between remote and local processes. The processes that use a socket can reside on the same system or different systems on different networks. Sockets are useful for both stand-alone and network applications. 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. A wide range of operating systems support socket APIs. i5/OS sockets support multiple transport and networking protocols. Socket system functions and the socket network functions are thread safe.                                  Programmers who use Integrated Language Environment® (ILE) C can re

What is Computer Architecture ? In computer engineering , computer architecture is a description of the structure of a computer system made from component parts. It can sometimes be a high-level description that ignores details of the implementation. At a more detailed level, the description may include the instruction set architecture design, microarchitecture design, logic design, and implementation. System Architecture Computer Organization : Computer organization helps optimize performance-based products. For example, software engineers need to know the processing power of processors. They may need to optimize software in order to gain the most performance for the lowest price. This can require quite a detailed analysis of the computer's organization. For example, in an SD card, the designers might need to arrange the card so that the most data can be processed in the fastest possible way. Computer organization also helps plan the selection of a processor for a particular proje

What is Data Structure ? A data structure is a specialized format for organizing, processing, retrieving and storing data. There are several basic and advanced types of data structures, all designed to arrange data to suit a specific purpose. Data structures make it easy for users to access and work with the data they need in appropriate ways. Most importantly, data structures frame the organization of information so that machines and humans can better understand it. In computer science and computer programming, a data structure may be selected or designed to store data for the purpose of using it with various algorithms . In some cases, the algorithm's basic operations are tightly coupled to the data structure's design. Each data structure contains information about the data values, relationships between the data and -- in some cases -- functions that can be applied to the data. For instance, in an object-oriented programming language, the data structure and its associated me

What is C Programming Language ? The C programming language is a procedural and general-purpose language that provides low-level access to system memory. A program written in C must be run through a C compiler to convert it into an executable that a computer can run. Many versions of Unix-based operating systems (OSes) are written in C and it has been standardized as part of the Portable Operating System Interface (POSIX). Today, the C programming language runs on many different hardware platforms and OSes such as Microsoft and Linux. Pros and cons of C The C language comes with a set of special characteristics, making it one of the most widely used languages of all time.

A   programming language   is a system of notation for writing   computer programs .Most programming languages are text-based   formal languages , but they may also be   graphical . They are a kind of   computer language .   The description of a programming language is usually split into the two components of   syntax   (form) and   semantics   (meaning), which are usually defined by a   formal language . Some languages are defined by a specification document (for example, the   C   programming language is specified by an   ISO   Standard) while other languages (such as   Perl ) have a dominant   implementation   that is treated as a   reference . Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.   Programming language theory   is the subfield of   computer science   that studies the design, implementation, analysis, characterization, and classification of programming languages.   Some Programming
