There are two types of fragmentation namely, Internal Fragmentation and External Fragmentation. Read this article to learn more about these two types of fragmentation and how they are different from each other. What is Internal Fragmentation? Internal fragmentation is defined as the difference between memory allocated and the memory space required by a process. ... Read More

A computer is a system, i.e. it consists of several parts. The two crucial parts of a computer system are – hardware and software. Those parts of computer system which are physical and visible are called the hardware. Whereas, the computer software are the sets of instructions and programs that enable the computer hardware to perform their functions. Both the hardware and software are dependent on each which means we must install the software in the hardware to make it functional. In the same way, the hardware parts of a computer must be present in the system to perform the ... Read More
