<u>Explanation</u>:
The establishment of the Abacus brought about one of the first counting device (calculator). This device was a mechanized computer that supported numeric calculations. However<u>, the process was entirely manual and mechanized. </u>This innovation led to;
First-generation of computers, although not entirely manually operated like Abacus, made use of vacuum tubes, were very big in size and could store only a small amount of information.
Second Generation of computers
unlike the first generation that uses vacuum tubes, this one came with new technology; the use of transistors. The computers were smaller in size than vacuum tubes.
Third Generation computers made use of IC (Integrated circuits) for the first time. Contained higher storage capacity and was more reliable than previous generations.
Fourth Generation computers became known as the personal computer generation. This generation brought the use of personal computers on a personal level as they use microprocessors, was easy to carry about, had larger storage capacity and faster speed of operations.
Fifth-generation of computers is known as the age of artificial intelligence. These computers were programmed with the ability to make decisions just like a human being would.
Explanation:
Time Constraint and Time Consuming: Nobody would carry out business when the market was closed. ... Limited Space: The old economy depended on physical space such as market places and offices before business transaction could take place.
Answer:
Moore's Law refers to Moore's perception that the number of transistors on a microchip doubles every two years, though the cost of computers is halved. Moore's Law states that we can expect the speed and capability of our computers to increase every couple of years, and we will pay less for them. Another tenet of Moore's Law asserts that this growth is exponential.
Answer:
description=open_file.read(12)
Explanation:
A programming language in computer is a set formal languages that comprises a set of instruction which produce various kinds of output. It is used ti implement algorithms in computer programming.
In the context, description=open_file.read(12) is the statement given to the computer as input which takes a variable named as open_file containing a file object and which reads the next 12 characters into the variable named as description.
