Answer:

Broadcast message

Explanation:

A broadcast message is a specialized type of message sent to all computers, or other networking devices, on a particular local area network(e.g Ethernet) or subnet. In the TCP/IP protocol, the broadcast message is sent when the network layer address is translated into a data-link layer address.

Examples of a broadcast message transmission are television signals sent from a source network to all viewers around the globe.

In a LAN (local area network), the address resolution protocol uses the concept of broadcast messaging to send an address resolution query to all the networking devices connected to the LAN.

Therefore, in essence, a broadcast message is sent from one source network device to multiple destination networking devices basically on the same network.

Answer:

Broadcast message

Explanation:

The network models like OSI and TCP/IP suites have standard layers and protocols that governs the communication of end devices in a network.

The TCP/IP suite model has four layers which are application, transport, internet and network access layers. The network access does the work of both the data-link and physical layer of the OSI model.

When the packet is encapsulated in a data-link header and trailer, and needs to be sent to another unknown host, a broadcast message is sent to all the computers in the network to retrieve the remote host address for a unicast transmission to take place.

Is The speed of microprocessor measured by Mega Bytes​
DiKsa [7]

Answer:

El microprocesador (o simplemente procesador) es el circuito integrado central más complejo de un sistema informático; a modo de ilustración, se le suele llamar por analogía el «cerebro» de un ordenador.1​

Es el encargado de ejecutar todos los programas, desde el sistema operativo hasta las aplicaciones de usuario; solo ejecuta instrucciones en lenguaje binario, realizando operaciones aritméticas y lógicas simples, tales como sumar, restar, multiplicar, dividir, las lógicas binarias y accesos a memoria.

Puede contener una o más unidades centrales de procesamiento (CPU) constituidas, esencialmente, por registros, una unidad de control, una unidad aritmético lógica (ALU) y una unidad de cálculo en coma flotante (conocida antiguamente como «coprocesador matemático»).

El microprocesador está conectado generalmente mediante un zócalo específico de la placa base de la computadora; normalmente para su correcto y estable funcionamiento, se le incorpora un sistema de refrigeración que consta de un disipador de calor, fabricado de algún material de alta conductividad térmica, como cobre o aluminio, y de uno o más ventiladores que eliminan el exceso del calor absorbido por el disipador. Entre el disipador y la cápsula del microprocesador usualmente se coloca pasta térmica para mejorar la conductividad del calor. Existen otros métodos más eficaces, como la refrigeración líquida o el uso de células peltier para refrigeración extrema, pero estas técnicas se utilizan casi exclusivamente para aplicaciones especiales, tales como en las prácticas de overclocking.

La medición del rendimiento de un microprocesador es una tarea compleja, dado que existen diferentes tipos de "cargas" que pueden ser procesadas con diferente efectividad por procesadores de la misma gama. Una métrica del rendimiento es la frecuencia de reloj que permite comparar procesadores con núcleos de la misma familia, siendo este un indicador muy limitado dada la gran variedad de diseños con los cuales se comercializan los procesadores de una misma marca y referencia. Un sistema informático de alto rendimiento puede estar equipado con varios microprocesadores trabajando en paralelo, y un microprocesador puede, a su vez, estar constituido por varios núcleos físicos o lógicos. Un núcleo físico se refiere a una porción interna del microprocesador casi-independiente que realiza todas las actividades de una CPU solitaria, un núcleo lógico es la simulación de un núcleo físico a fin de repartir de manera más eficiente el procesamiento. Existe una tendencia de integrar el mayor número de elementos dentro del propio procesador, aumentando así la eficiencia energética y la miniaturización. Entre los elementos integrados están las unidades de punto flotante, controladores de la memoria RAM, controladores de buses y procesadores dedicados de vídeo.

What do you understand by multitasking?Explain cooperativemultitasking ?
Nadusha1986 [10]

Answer: Multitasking is the ability of the operating system by which a processor is able to process multiple task at the same time.

Cooperative multitasking is non preemptive multitasking where the processor is assigned to a single process and does not preempt  until it completes its jobs or moves to a waiting state.

Explanation:

In Multitasking jobs are executed at a faster rate than as many jobs or tasks can be assigned to the processor at the same time.

In cooperative multitasking due to the non preemptive nature a single job could be assigned to the cpu at a time.

Zolol [24]

Answer:

External EMI/RFI

Explanation:

The EMI stands for Electromagnetic interference. It is a radio frequency spectrum which is disturbance that is created by the external source which affects the electric circuit by an electromagnetic induction or conductance. It is also called as the RFI or the radio-frequency interference.

In the context, the three Cat 5e cable were run from the office area to the three computers in the machine shop. The users reports a problem of a very slow network performance and also the switch reports CRC errors. This is mainly caused due to the external EMI or the external RFI.
