Cuando se creo argentina​
vekshin1

Answer:

Argentina se creó tras su independencia respecto de España el 9 de julio de 1816, tras 6 años de guerra por la independencia del país, donde líderes como Manuel Belgrano, Martín Miguel de Güemes y José de San Martín derrotaron a los españoles.

La unidad nacional de los argentinos, a su vez, se originó tras las invasiones inglesas de 1806 y 1807, y se consolidó tras la conquista de España por parte de los Bonaparte, que dio origen a la Revolución de Mayo de 1810, donde los argentinos decidieron imponer un gobierno propio.

Typically, when an organization purchases Internet access from an Internet Service Provider (ISP), the ISP will grant it
hodyreva [135]

Answer:

(B) A single public IP address that it can use for NAT

Explanation:

Because the IPV4 IP protocol is still used today, the number of available IP addresses is limited (only 4,294,967,296 addresses in the world), for this reason, the most correct practice is the assignment of a single public IP to those companies that acquire services from an ISP, with some few exceptional cases of companies that own several.

So that the company's addressing can be executed successfully, the use of NATs is enabled, this allows the translation of network addresses, allowing the company to have as many private networks as necessary and that these can be communicated Correctly with the global network, the Internet, through the public IP of the company.

When measuring an unknown voltage with an analog VOM, you should first A. ground the circuit. B. set the switch to the lowest ra
ale4655 [162]

<u>Answer:</u>

The correct answer option is D. set the switch to the highest range and then move it to a range that gives the most accurate reading.

<u>Explanation:</u>

When measuring an unknown voltage with an analog VOM, one should set the meter to the highest range and then move it to a range that gives the most accurate reading.

The reason being that the analog meters indicate the measurement of voltage by moving a needle  across a physical card by printing numbers on it.

So in case the voltage is nearly 100 times the full range to which the meter is set,  then its needle will try move to a position which will be 100 times the highest number on the meter.
