The term 'software' refers to the set of electronic program instructions or data a computer processor reads in order to perform a task or operation. In contrast, the term 'hardware' refers to the physical components that you can see and touch, such as the computer hard drive, mouse, and keyboard.

Software can be categorized according to what it is designed to accomplish. There are two main types of software: systems software and application software.

RAM (Random Access Memory) is the place in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device's processor.

RAM is much faster to read from and write to than other kinds of storage in a computer, such as a hard disk drive (HDD), solid-state drive (SSD) or optical drive.

Data remains in RAM as long as the computer is running. When the computer is turned off, RAM loses its data. When the computer is turned on again, the OS and other files are once again loaded into RAM, usually from an HDD or SSD.

Software, instructions that tell a computer what to do. Software comprises the entire set of programs, procedures, and routines associated with the operation of a computer system. A set of instructions that directs a computer's hardware to perform a task is called a program, or software program.

Random-access memory (RAM) is a form of computer data storage which stores frequently used program instructions to increase the general speed of a system. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory

RAM a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers. It is a volatile memory.

Types of RAM :

DRAM (Dynamic Random Access Memory) - The term dynamic indicates that the memory must be constantly refreshed or it will lose its contents.

SRAM (Static Random Access Memory) - The term static is derived from the fact that it doesn't need to be refreshed like dynamic RAM.

Computer is versatile in nature. Multi-processing features of computer makes it quiet versatile in nature.

It can control a variety of jobs in various field. The computer can performing any job provided he had a set of program and its related data.

One moment, it is preparing the results of particular examination, the next moment it is busy preparing electricity bills, and in between it may be helping an office secretary to trace an important letter in seconds.

Key difference: Hardware is the physical aspect of the computer, the thing we can touch, such as monitor, hard drive, etc. Software is the non-physical aspect which includes the operating system, applications, programs, etc.

Hardware is the actual components that your computer is made of, such as the monitor, keyboard, CPU, etc. Without hardware, the computer would not exist and the software would have nothing to run on. The software, on the other hand, is any program that you load onto a computer, such as the operating system, the server, the web browser, media player, etc. It is the code and instructions that tells the computer hardware how to operate.

Software is categorized into three different types: system software, programming software and application software

.There are various types of hardware, including input devices ; output devices ; data storage ; data ports etc.
