Ayuda para la tarea de tecnología de la información
La ayuda para la asignación de tecnología de la información puede proporcionar a los usuarios información de muy alta calidad sobre la vanguardia de la ciencia y la tecnología. Hay datos de información categorizados muy detallados y el software en sí no tiene permisos para usarlos, por lo que todos pueden disfrutar de la tecnología al máximo.
Inusualmente, también es una excelente organización de contenidos para la tecnología y la vida. Conecta usuarios y marcas para producir contenido interesante y profesional. Incluye información técnica, reseñas detalladas, consejos sobre habilidades y experiencias de productos, etc. Tiene formatos de contenido gráfico, de video e infomercial y cubre las principales plataformas de nuevos medios.
- Which of the following is a benefit of using a simulation instead of an experiment to make a prediction? Select two answers. A simulation allows investigation of a phenomenon without the real-world limitations on time, safety, or budget. A simulation can be used to model real-world events that are impractical for experiments. A simulation always produces the same output so its results can be verified. A simulation produces results that are more accurate than experimental results.
- A programmer has a need to round many numeric values to the nearest integer. Which of the following best explains the benefit of using a list as a data abstraction in this situation? A Keeping the numeric values in a list makes it easier to round a number to the nearest integer. B Keeping the numeric values in a list makes it easier to apply the same computation to every data element C Keeping the numeric values in a list makes it easier to prevent a program from unintentionally changing the value of a variable. D Keeping the numeric values in a list makes it easier to prevent a program from attempting to access an index beyend the length of the list
- 19 Which of the following is a benefit of using a list as a data abstraction in a program? A Lists often allow their size to be easily updated to hold as many data values as needed. B Lists convert all elements to strings so that they can be inspected character-by-character. C Lists prevent duplicate data values from appearing in the list. D Lists are used to store all input data so that there is a running record of all user input. Mark for Review
