C++ is a programming language commonly used for developing operating systems, browsers, games, and other complex software applications. It is an extension of the C programming language and includes features such as object-oriented programming, templates, and exception handling. Proficiency in C++ requires knowledge of its syntax, data types, control structures, memory management, and libraries.

C++14 is a version of the programming language C++. It introduces several new features and improvements, such as simplified syntax, enhanced constexpr support, and improved type inference. It also includes features for better memory management, such as smart pointers and lambda expressions. Knowledge of C++14 is important for developers who want to write efficient and effective code for a wide variety of applications.

Inter-Process Communication refers to the mechanisms that allow processes to communicate and synchronize their actions when executing concurrently. This skill encompasses various methods such as message passing, shared memory, and remote procedure calls, which facilitate data exchange and coordination between processes. Knowledge of Inter-Process Communication is used to enhance system performance, ensure data integrity, and manage resource sharing in multi-threaded or distributed environments.

Shared Memory refers to a memory management capability that allows multiple processes to access a common memory space. This skill encompasses the understanding of synchronization mechanisms and data consistency techniques that enable efficient communication and data sharing between processes. Knowledge of Shared Memory is used to enhance performance in applications requiring high-speed data exchange, such as real-time systems and parallel computing environments, by minimizing the overhead associated with inter-process communication.

Socket Programming refers to the ability to establish a connection between two devices over a network and exchange data between them. It involves creating, manipulating, and managing sockets, which are endpoints for communication. This specialized skill requires knowledge of programming languages, network protocols, and server and client operating systems. Socket programming is essential for developing applications that require real-time communication, such as messaging apps, online gaming, and video conferencing software.
