Answer:
Block 2
Explanation:
Cache mapping is a technique by which the contents of main memory are brought into the cache memory. we have three different types of cache mapping these are; direct, fully associative and k-way set associative mappings. In direct mapping such as the scenario above, the cache has one block in each set, so it is organized into X = Y sets, as such a particular block of main memory can map to only one particular line of the cache and the formula for determining the line number of cache to which a particular block can map is given by (main memory block address) %(number of lines in cache)
Answer:
La biblioteca estándar de C (también conocida como libc) es una recopilación de archivos de cabecera y bibliotecas con rutinas, estandarizadas por un comité de la Organización Internacional para la Estandarización (ISO), que implementan operaciones comunes, tales como las de entrada y salida o el manejo de cadenas. A diferencia de otros lenguajes como COBOL, Fortran, o PL/1, C no incluye palabras clave para estas tareas, por lo que prácticamente todo programa implementado en C se basa en la biblioteca estándar para funcionar.
Explanation:
System Software
Systems software<span> are programs that manage the resources of the computer system and simplify applications programming. They include software such as the operating system, database management systems, networking software, translators, and software utilities.</span>
Application Software
Application software<span> are programs that direct the performance of a particular use, or application, of computers to meet the information processing needs of end users. They include [email protected] software such as word processing and spreadsheet packages, as well as internally or externally developed software that is designed to meet the specific needs of an organization.</span>
<span>Software trends have been away from custom-designed one-of-kind programs developed by the professional programmers or end users of an organization toward the use of [email protected] software packages acquired by end users from software vendors.</span>
Two types of packages are available:
<span>1. Vertical packages - assist users within a specific industry segment. Examples include packages that help to manage construction projects, keep track of inventory of hospitals, or fast-food outlets.</span>
<span>2. Horizontal packages - can perform a certain general function, such as accounting, or office automation, for a range of businesses.</span>
