  2. Frontend and backend - Wikipedia

    en.wikipedia.org/wiki/Frontend_and_Backend

    In software development, frontend refers to the presentation layer that users interact with, while backend involves the data management and processing behind the scenes. In the client–server model , the client is usually considered the frontend, handling user-facing tasks, and the server is the backend, managing data and logic.

  3. Infrastructure as code - Wikipedia

    en.wikipedia.org/wiki/Infrastructure_as_code

    Infrastructure as Code (IaC) allows you to manage servers and their configurations using code. There are two ways to send these configurations to servers: the 'push' and 'pull' methods. In the 'push' method, the system controlling the configuration directly sends instructions to the server.

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})

  6. LLVM - Wikipedia

    en.wikipedia.org/wiki/LLVM

    LLVM allows code to be compiled statically, as it is under the traditional GCC system, or left for late-compiling from the IR to machine code via just-in-time compilation (JIT), similar to Java. The type system consists of basic types such as integer or floating-point numbers and five derived types : pointers , arrays , vectors , structures ...

  7. C syntax - Wikipedia

    en.wikipedia.org/wiki/C_syntax

    A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.

  8. Relocation (computing) - Wikipedia

    en.wikipedia.org/wiki/Relocation_(computing)

    Relocation is the process of assigning load addresses for position-dependent code and data of a program and adjusting the code and data to reflect the assigned addresses. [1] [2] Prior to the advent of multiprocess systems, and still in many embedded systems, the addresses for objects are absolute starting at a known location, often zero.

  9. tf–idf - Wikipedia

    en.wikipedia.org/wiki/Tf–idf

    TFPDF was introduced in 2001 in the context of identifying emerging topics in the media. The PDF component measures the difference of how often a term occurs in different domains. Another derivate is TF–IDuF. In TF–IDuF, [15] idf is not calculated based on the document corpus that is to be searched or recommended. Instead, idf is ...
