SpyIntel [72]

Answer:

Interrupt (INT) helps operating system to stop work on one process and start work on other process using interrupt signals.

Explanation:

Purpose of interrupts:

• Interrupts are useful when an I/O device needs to be serviced only occasionally at low data transfer rate.

• For example, when a peripheral requires the attention of the processor to perform an I/ O operation.

A trap:

• also known as an exception or a fault, is typically a type of synchronous interrupt caused by an exceptional condition

• is a software-generated interrupt.

• For example it's caused by division by zero or invalid memory access.

Can traps be generated intentionally by a user program?  Yes.

If so, for what purpose?  

• the usual way to invoke a kernel routine (a system call) because those run with a higher priority than user code.  

• Handling is synchronous, so the user code is suspended and continues afterwards.

• In a sense they are active - most of the time, the code expects the trap.

Cuento sobre la creación de algún videojuego​
Y_Kistochka [10]

Answer:

Historia de los videojuegos

Los inicios

Durante bastante tiempo ha sido complicado señalar cual fue el primer videojuego, principalmente debido a las múltiples definiciones de este que se han ido estableciendo, pero se puede considerar como primer videojuego el Nought and crosses, también llamado OXO, desarrollado por Alexander S.Douglas en 1952. El juego era una versión computerizada del tres en raya que se ejecutaba sobre la EDSAC y permitía enfrentar a un jugador humano contra la máquina.

En 1958 William Higginbotham creó, sirviéndose de un programa para el cálculo de trayectorias y un osciloscopio, Tennis for Two (tenis para dos): un simulador de tenis de mesa para entretenimiento de los visitantes de la exposición Brookhaven National Laboratory.

Este videojuego fue el primero en permitir el juego entre dos jugadores humanos. Cuatro años más tarde Steve Russell, un estudiante del Instituto de Tecnología de Massachussets, dedicó seis meses a crear un juego para computadora usando gráficos vectoriales: Spacewar.

En este juego, dos jugadores controlaban la dirección y la velocidad de dos naves espaciales que luchaban entre ellas. El videojuego funcionaba sobre un PDP-1 y fue el primero en tener un cierto éxito, aunque apenas fue conocido fuera del ámbito universitario.

En 1966 Ralph Baer empezó a desarrollar junto a Albert Maricon y Ted Dabney, un proyecto de videojuego llamado Fox and Hounds dando inicio al videojuego doméstico. Este proyecto evolucionaría hasta convertirse en la Magnavox Odyssey, el primer sistema doméstico de videojuegos lanzado en 1972 que se conectaba a la televisión y que permitía jugar a varios juegos pregrabados.
