<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.
I basically agree with the answer B.
Answer:
Explanation:
Assuming you have Windows 8 or 10 as the operating system, you would need to do the following. In the search input in the taskbar search for "Create a System Restore Point". In this window, navigate to the System Protection tab. Here, you need to click on the drive you want, we can do C first, and click on the button that says "configure". Here you want to turn on System Protection and set the disk space to 5%. Now click apply and ok and repeat for drive D.
Once that is done you will need to create a manual restore point by clicking the button that says create and giving it the name of your choice.
Answer:
when make a task list you would not include commands that are for any specific language like C++
Explanation:
pseudocode should be universal. So when creating the task list, you would not include commands that are for any specific language like C++, java, C#, or perl. The point of pseudocode is to design a program that can be translated in to any language.
Answer:
The negative effects of computer use on the environment There are several effects computer use has on the environment. Not only does it affect the environment but also human health.
Explanation:
First of all, sometimes people (especially in businesses) print unnecessary large amounts of files, emails or things from the internet which wastes paper and harms trees. People who use computers never really turn off the device which wastes electricity that could have been saved and reduce the amount of burning of fossil fuel.
Secondly, computers are made of heavy metals and dangerous chemicals. Heavy metals including Lead, Mercury,Beryllium,Cadmimum, PCV e.t.c
These metals and chemicals contribute to global warming because from these discarded computers it causes water contamination and air pollution.
