A series of instructions written in a programming language for a computer to follow is referred to as a computer program.
<h3>
What is program?</h3>
Software, which also contains documentation and other intangible components, comprises computer programs as one of its components.
The source code of a computer program is the version that can be read by humans. Since computers can only run their native machine instructions, source code needs to be run by another software.
Using the language's compiler, source code may be converted to machine instructions. (An assembler is used to translate programs written in machine language.) An executable is the name of the generated file.
Therefore, A series of instructions written in a programming language for a computer to follow is referred to as a computer program.

Answer:
a. 255.255.255.0 (class C)
b. 255.255.255.224
Explanation:
Here, we want to give the implied subnet mask of the given classful IPV4 address
We proceed as follows;
Given IPv4 address: 200.200.200.200
Classes
Class A : 0.0.0.0 to 127.255.255.255
Class B: 128.0.0.0 to 191.255.255.255
Class C: 192.0.0.0 to 223.255.255.255
Class D: 224.0.0.0 to 239.255.255.255
so 200.200.200.200 belongs to Class C and it's subnet mask is 255.255.255.0
In CIDR(Classless Inter Domain Routing)
subnet /27 bits means 27 1s and 5 0s. so subnet
i.e 11111111.11111111.11111111.11100000 which in dotted decimal format is 255.255.255.224 .
