Answer:
The major characteristics of computers are the following:
Speed : A powerful computer is capable of executing about 3 million calculations per second.
Accuracy : A computer's accuracy is consistently high; if there are errors, they are due to errors in instructions given by the programmer.
Reliability : The output generated by the computer is very reliable as long as the data is reliable.
Memory/Storage Capacity : The computer can store large volumes of data and makes the retrieval of data an easy task.
Versatility: The computer can accomplish many different things. It can accept information through various input-output devices, perform arithmetic and logic operations, generate a variety of outputs in a variety of forms, etc.
Automation: Once the instructions are fed into computer it works automatically without any human intervention.
Diligence: A computer will never fail to perform its task due to distraction or laziness.
Convenience: Computers are usually easy to access, and allow people to find information easily that without a computer would be very difficult.
Flexibility: Computers can be used for entertainment, for business, by people who hold different ideals or who have varied goals. Almost anyone can use a computer, and computers can be used to assist with almost any goal.

Health informatics is an interdisciplinary field which incorporates theory and methodology from fields in computer science is True.
True
<u>Explanation:</u>
To capture patient health information they used interdisciplinary field which is consists patient information and they diseases and cure treatment taken for that patient. All information is store in digital formatted.
The patient information is stored such as health informatics, nurse and doctor treatment, health treatment, medicine details, clinics information.
Health informatics are used to do further analysis on patient health. Doctors are using this information for their further treatment for their patient also.
Information are also can be used as IOT information so that patient information are readily available.
Answer:
Let f be a function
a) f(n) = n²
b) f(n) = n/2
c) f(n) = 0
Explanation:
a) f(n) = n²
This function is one-to-one function because the square of two different or distinct natural numbers cannot be equal.
Let a and b are two elements both belong to N i.e. a ∈ N and b ∈ N. Then:
f(a) = f(b) ⇒ a² = b² ⇒ a = b
The function f(n)= n² is not an onto function because not every natural number is a square of a natural number. This means that there is no other natural number that can be squared to result in that natural number. For example 2 is a natural numbers but not a perfect square and also 24 is a natural number but not a perfect square.
b) f(n) = n/2
The above function example is an onto function because every natural number, let’s say n is a natural number that belongs to N, is the image of 2n. For example:
f(2n) = [2n/2] = n
The above function is not one-to-one function because there are certain different natural numbers that have the same value or image. For example:
When the value of n=1, then
n/2 = [1/2] = [0.5] = 1
When the value of n=2 then
n/2 = [2/2] = [1] = 1
c) f(n) = 0
The above function is neither one-to-one nor onto. In order to depict that a function is not one-to-one there should be two elements in N having same image and the above example is not one to one because every integer has the same image. The above function example is also not an onto function because every positive integer is not an image of any natural number.
Is there a picture to go along with this? I don’t see one and an willing to help!
