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.

When a Select Case statement executes, the value of the test expression is compared with the values that follow each of the ____
goldenfox [79]

Answer:

Case

Explanation:

In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.

Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.

For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.

A Select Case statement can be defined as a conditional statement that avails software developers or programmers the ability to test a variable by comparing it with a list of values.

In a Select Case statement, each variable is referred to as a Case.

Generally, when a Select Case statement executes, the value of the test expression is compared with the values that follow each of the Case keywords.

Answer:

Following are the solution to this question:

Explanation:

This algorithm uses the divide and rule approach works, which splits the list into two sublists depending on if they are smaller or larger than the pivotal factor. It has O(n*log n) complexity.

It splits down the list in more than one version frequently till every sublist becomes based on a single element and fuses it to offer an ordered array. The merge type works according. It has O(n*log n) complexity.

Please find the attachment file of the sorting.

atroni [7]
Give the type and value of each result of the following Java expressions. a. (5 / 2) * 2.0  type is float value is 4.0 b. (5/2.0) * 2 type is integer value is 5c. "1.3" + "5.2" type is string value is 1.35.2d. 1 + 7.0 + "2" + "x"  this will produce an error because we cannot add variables of different type
