A Linux-based system is a modular Unix-like operating system, deriving much of its basic design from principles established in Unix during the 1970s and 1980s. Such a system uses a monolithic kernel, the Linux kernel, which handles process control, networking, access to the peripherals, and file systems.
The Linux Programming Interface is a well-regarded [3] work on Linux systems programming and is available for readers in several languages. [4] The Linux kernel API to userspace discussed in the book consists of both the System Call Interface and the GNU C Library. In-kernel APIs are not discussed in the book, neither are ABIs.
A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture. Sockets are created only during the lifetime of a ...
Network programming traditionally covers different layers of OSI/ISO model (most of application-level programming belongs to L4 and up). The table below contains some examples of popular protocols belonging to different OSI/ISO layers, and popular APIs for them.
x86 assembler. License. BSD 2-clause. Website. www .nasm .us. The Netwide Assembler ( NASM) is an assembler and disassembler for the Intel x86 architecture. It can be used to write 16-bit, 32-bit ( IA-32) and 64-bit ( x86-64) programs. It is considered one of the most popular assemblers for Linux and x86 chips. [3]
Network architecture. Network architecture is the design of a computer network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used. In telecommunication, the specification of a network ...
A Unix architecture is a computer operating system system architecture that embodies the Unix philosophy. It may adhere to standards such as the Single UNIX Specification (SUS) or similar POSIX IEEE standard. No single published standard describes all Unix architecture computer operating systems — this is in part a legacy of the Unix wars .
Kernel (operating system) An oversimplification of how a kernel connects application software to the hardware of a computer. The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts ...
