Explanation / Answer

1) In 4KB there are a total of 4096 Bytes(1024*4)

In 4MB there are a total of 4194304 Bytes(1024*1024*4)

In 4 GB there a total of 4294967296 Bytes(1024*1024*1024*4)

2) There a total of 32 Bits in 4 Bytes(8*4=32)

There are a total of 8192 Bits in 1KB(1024*8)

There are a total of 16777216 Bits in 2MB(1024*1024*8*2)

3) Java is a purely object oriented programming language since even a simple program needs to be called in a class and can be accessed only by using objects.

4) Analog data id sata which is continous whereas digital data is data in the form of 0's and 1's

5) Hardware are physical components that can be physically touched.

Central Processing Unit is a Unit that performs all the needed operations by the Computer.

Application Software is software designed to perform a froup of coordinated functions tasks or activities for the benefit of the user.

System software is a computer program that is used to run computers hardware and application programs

Memory is a storage location of data.

6) Binary system is used since computers memory is measured in terms of Bytes and its the simplest way to represent the data
