Answer:
The development of computers from the beginning to what we see now is called the computer generations. It is gradual advancement in the technology in the making of the computer.
Explanation:
The generation in computer technology can be defined as the development or the change in the technology in the computer as it was used. There were five generations of computer development. They were :
1. First Generation computers
In this generation, vacuum tubes was used in the circuits. It dated from 1946 to 1959.
2. Second Generation computers
These are transistors based computers. This generation ranges from 1959 to 1965.
3. Third Generation computers
This generation computers were Integrated circuit based. The generation stared in 1965 and ended in 1971.
4. Fourth Generation computers
The computers of this generation used VLSI microprocessor in the circuits. The period of the 4th generation computers are from 1971 to 1980.
5. Fifth Generation computers
The computers of this generation used ULSI microprocessor in the circuits. The 5th generation computers started from 1980s.
Where are the answer choices?
Answer:
Only the last number of each IP address will be unique
Explanation:
Subnet Mask is used to identify the two parts of the IP address. One is the network part that should be same for one network, and other is host part that will vary with number of computer or devices that are connected to the network.
Subnet mask is 32 bit address that are divided in 4 equal parts of 8 bits. Each 8 bit converted to decimal by varying different bits to generate 256 different decimal number combinations. It means we can vary the address range between 0 to 255. So If any 8 bit portion is 255 that means, in this section we cannot add host address.
<u>For Example</u>
In given case,
Subnet Mask = 255.255.255.0
That means first three portions are fixed and has been allocated for network part.
The forth portion is 0 that means we can change this portion in IP address up to 255 different addresses.
So the IP address that is given can be vary as:
10.1.10. 186
10.1.10 This portion is network portion, this cannot be vary.
only the number 186 is the unique address that is particularly assigned to the devices and is vary between 0 to 255.

Explanation:
"Why the computer is called diligent
Versatile machine"
Computer is called versatile machine because it is used in almost all the fields for various purposes.Because it can perform the task repeatedly without loosing its speed and accuracy for a long time.They are versatile because they can be used for all sorts of task.They can also do many of the same tasks in different ways.Computer is the electronic device which perform the logical and mathematical calculation.Computer is known as the versatile machine because it is very fast in every field and its part of life without it was cannot imagine life.
It can do the work faster and in every field the computer is used for making their work faster.
It can perform the work fast so it is called versatile machine.
Advantages of versatile machine:
- Computer are very fast due to which thousand of job can be performed within the short period of time.
- Complex mathematical problems and logical operations can be solved by using this computer.
- As computer is versatile device,multiple task like communication,graphics,documentation can be done.
Disadvantages of versatile machine:
- Computers are machine hence they have no brain so they work according to the program instruction set inside it.
- It is an electronic deice and it uses electronic sources to work,So it is very risk to store data and information on the computer independently because some electric and electronic damages may damage the data.So we have to make regular backup of the data.
