The document discusses making a presentation comparing weather in America and New Zealand. It instructs the reader to include 5 pictures, one from each country showing typical weather conditions.
La transmisión asíncrona ocurre cuando el proceso de sincronización entre el emisor y receptor se realiza en cada carácter transmitido, en lugar de mantener una sincronización continua. En la transmisión asíncrona, cada carácter se delimita con bits de inicio y fin y opcionalmente un bit de paridad, lo que permite la transmisión de datos sin una sincronización de relojes precisa entre el emisor y receptor.
El documento describe los conceptos de procesos concurrentes, sincronización de procesos, secciones críticas, semáforos y monitores. Explica cómo se pueden usar semáforos y monitores para garantizar la exclusión mutua y el progreso de los procesos concurrentes al acceder recursos compartidos. También cubre temas como comunicación entre procesos a través de memoria compartida y sistemas de mensajes.
El documento describe varios algoritmos para resolver el problema de la sección crítica en sistemas concurrentes. Introduce el problema de la carrera y presenta soluciones de software como los algoritmos de Peterson y Bakery que garantizan exclusión mutua y progreso para dos y más procesos respectivamente. También cubre soluciones de hardware como desactivar interrupciones y usar instrucciones de prueba y establecimiento atómico.
En un sistema multiprogramado con un único procesador, los procesos se intercalan en el tiempo para dar la apariencia de ejecución simultánea. Aunque no se consigue un procesamiento paralelo real, la ejecución intercalada produce beneficios en la eficiencia y estructuración de los programas debido a que evita periodos de inactividad del procesador.
El documento habla sobre la sincronización de procesos concurrentes. Explica que los procesos concurrentes deben comunicarse y sincronizarse para cooperar, ya que de lo contrario podría darse inconsistencia de datos. Describe el problema de la sección crítica, donde fragmentos de código crítico no deben ejecutarse simultáneamente, y presenta soluciones como el algoritmo de Dekker para lograr exclusión mutua y progreso de los procesos.
Comunicación y Sincronizacion de ProcesosLorena Ramos
Los procesos concurrentes pueden competir por recursos o cooperar compartiendo información. La sección crítica es la región del código donde un proceso accede a un recurso compartido. Se deben evitar las condiciones de competencia mediante la exclusión mutua en la sección crítica. Existen soluciones basadas en variables de cerradura, alternancia estricta, semáforos, monitores y paso de mensajes para garantizar la exclusión mutua.
The document provides instructions for creating a modern world plan project in 3 steps: include pictures and facts about a modern wonder in iMovie; do research and include interesting words learned; ask a parent or teacher for additional persuasive facts or knowledge beyond what was found through Google.
To make a nice iMovie, keep it around a minute and a half long, include animations and music to enhance the video, and most importantly have fun creating the iMovie.

A student is asked to create a 1-1/2 minute iMovie about the inside of a cyclone using only 3 pictures about a cyclone. The iMovie should be created to show the inside of a cyclone using 3 cyclone pictures within the 1-1/2 minute time limit.
The document provides instructions for creating a 3 minute iMovie project that must be exactly 3 minutes and 30 seconds in length and should include lots of weather pictures set to a song.
This document provides instructions for creating an iMovie slideshow on cloud types and weather. It instructs students to make a slideshow with information on different cloud types, their functions, and a minimum of 4 pictures. Students should use provided webquest resources and their own research to complete the task. The document tells students to start filming their iMovie by clicking the camera icon and pretend they are explaining clouds to someone unfamiliar with cloud types. It concludes by wishing students a happy filming and good day.
Glaciers are large bodies of ice that form on land from the accumulation and compaction of snow over many years. Students are instructed to create an iMovie with a picture of a glacier along with its name and location, and to include 5 interesting facts about how glaciers are formed in the video. The assignment also prompts including where glaciers can be found.
Snow forms during the winter season when temperatures are cold enough for water vapor in the atmosphere to freeze into ice crystals and fall as snowflakes. Signs of snow include dropping temperatures, dark clouds and a white layer on the ground or surfaces. Snow falls most heavily in mountainous areas and regions closer to the poles where temperatures remain below freezing for longer periods.
The document provides instructions for a presentation on tornadoes, cyclones, and hurricanes. It specifies that the presentation should include an introduction paragraph, individual paragraphs on each weather event describing what they are, how they are created, and what makes them different. It also requests a paragraph comparing the most and least powerful events and diagrams and a photo for each. The presentation should be between 2-3 minutes and include at least one speech.
The document provides instructions for creating a Prezi presentation, requiring at least 3 pictures, 7 facts, and 2 untrue facts, as well as 4 questions.
The document provides instructions for creating a 1-minute voice recording that discusses what causes floods to occur. The recording needs to include the creator's voice and discuss what triggers floods to start.

The document instructs the reader to write a 3 line poem about how the sun affects temperature. The poem must include 3 things about the sun and use the word "sun" in the poem.
Storms start when warm and cold air masses collide, causing rising and falling air that develops into storm clouds. The iMovie should discuss the science of how storms form from air temperature differences and air pressure changes in under 4 minutes.
Hurricanes form over warm ocean waters and require moisture and gentle winds that allow the system to rotate. The formation and strength of hurricanes can impact coastal regions and communities, so understanding their behavior is important for preparedness and safety. Monitoring ocean and atmospheric conditions helps forecasters detect when and where hurricanes may develop so communities have time to protect lives and property.
The document discusses why the North is hotter than the South. It instructs the reader to write why they think the North is hotter than the South in 5 boxes. However, no other details or explanations are provided in the short 3 sentence document.
Clouds produce rain through a process of water evaporating from surfaces like oceans and lakes into the air, rising into clouds where droplets form around particles, and becoming heavy enough to fall as precipitation.
The document discusses making an iMovie about New Zealand that includes at least 7 facts about the country's wonders and history. It suggests filming and editing video footage that highlights New Zealand's past and age in the short movie.
This document outlines the requirements for a short video or slideshow on underwater locations, requesting the content be between 2-3 minutes and include pictures from the underwater world rather than focusing specifically on the "7 wonders".
The document instructs the reader to create a Voki that shares what they learned about the 7 natural wonders from a previous assignment in 3 sentences or less.
The document discusses putting music and pictures on an iMove device. It mentions storing pictures on the iMove and making notes about what pictures are stored.
