Answer:
Brief History Of Computer. The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. ... Other developments continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built.
Explanation:
Computers and electronics play an enormous role in today's society, impacting everything from communication and medicine to science.
Although computers are typically viewed as a modern invention involving electronics, computing predates the use of electrical devices. The ancient abacus was perhaps the first digital computing device. Analog computing dates back several millennia as primitive computing devices were used as early as the ancient Greeks and Romans, the most known complex of which being the Antikythera mechanism. Later devices such as the castle clock (1206), slide rule (c. 1624) and Babbage's Difference Engine (1822) are other examples of early mechanical analog computers.
The introduction of electric power in the 19th century led to the rise of electrical and hybrid electro-mechanical devices to carry out both digital (Hollerith punch-card machine) and analog (Bush’s differential analyzer) calculation. Telephone switching came to be based on this technology, which led to the development of machines that we would recognize as early computers.
The presentation of the Edison Effect in 1885 provided the theoretical background for electronic devices. Originally in the form of vacuum tubes, electronic components were rapidly integrated into electric devices, revolutionizing radio and later television. It was in computers however, where the full impact of electronics was felt. Analog computers used to calculate ballistics were crucial to the outcome of World War II, and the Colossus and the ENIAC, the two earliest electronic digital computers, were developed during the war.
With the invention of solid-state electronics, the transistor and ultimately the integrated circuit, computers would become much smaller and eventually affordable for the average consumer. Today “computers” are present in nearly every aspect of everyday life, from watches to automobiles.
Answer:
Question is incomplete. it needs a topology diagram and also it needs Router R1 table. I assume User has access to the topology and Routing table.
Below Configuration will help to fix ACL problem
Hosts from the 172.16.0.0/16 network should have full access to Server1, Server2 and Server3 but this is not currently the case, as L1 can’t communicate to Server2 or Server3.

Answer:
B) prompt
Explanation:
Prompt tells a user that it's ready to receive commands by displaying a specific set of characters.
For example in <em>windows</em> it can be:
C:\Temp>, The prompt states that user is currently in <em>C </em>drive <em>Temp</em> directory.
in <em>Linux </em>based operating systems it can be:
[email protected]:~/Documents$
where it is in the format [email protected]:~directory$
