The software is a kind of programs that enable a user to perform some specific task or used to operate a computer. It directs all the peripheral devices on a computer system - what to do and how to perform work. Without Software, we can’t operate hardware and perform any calculations. A computer system can be divided into three components: the hardware, the software and the users. The software can be further divided into mainly two parts: Application software and System Software. Bare use of hardware is not easy, so to make it easy software is created.

Today Operating System can run multiple processes. But we know that only one process can be executed at the same time. Then to arrange and control the numerous processes in the system and utilize the CPU efficiently, some scheduling algorithm used by CPU.

Definition: The operating system provides us a graphic interface to give the command to the computer system. But system can’t understand these commands directly. Translation of code into binary language done by the core component of an operating system (OS), i.e., KERNEL. User deal with the lowest layer of kernel and then kernel deal with system.

What is Software: Computer software, or simply software, is a kind of programs that enable a user to perform some specific task or used to operate a computer. It directs all the peripheral devices on computer system - what to do and how to perform a task. PC Software plays a role of mediator between user and computer hardware. Without Software, a user can’t perform any task in digital computer.

Cache definition : The Cache Memory (Pronounced as "cash") is the volatile computer memory which is very nearest to the CPU so also called CPU memory, all the Recent Instructions are Stored into the Cache Memory. It is the fastest memory that provides high-speed data access to a computer microprocessor. Cache meaning is that it is used for storing the input which is given by the user and which is necessary for the computer microprocessor to Perform a Task. But the Capacity of the Cache Memory is too low in compare to Memory (random access memory (RAM)) and Hard Disk.

What is RAM (pronounced as raem), Ram full form " random access memory " and is volatile. First we'll tell you what RAM memory alternatively referred to as main memory, primary memory, or system memory, Random Access Memory (RAM) in a computer system, it is also sometimes known as read-write memory or RWM, then we'll go over how RAM works in Macintoshes and pcs. Also, there are different kinds of RAM, including VRAM, PRAM, DRAM and SRAM

Data base management system (DBMS) represent the management of data which includes various processes like collection of related data , storing and retrieving them, using set of programs for easy and effective manner.   While it may sound quit simple and easy but in reality it is not. As the bulk of data increases with the complexity of systems and multiple process running head to head it leads to most feared complication called Deadlock. It is nightmare for the developers and programmers. We will be discussing in detail everything about this evil Deadlock in our following article below. Starting with the definition first.

The database is the location to store the data. Firstly we used excel sheet to store the data. However, it has some problem with data integrity and redundancy problem. This problem solved by E.F. Codd proposed a model in 1970. This model was straightforward. It used the concept of mathematical relation which looks like a table.

An embedded system is a complex system also known as an integrated system; It has software embedded into hardware (also known as Firmware) to perform specific tasks or a single task. It typically contains one or more microprocessors for executing a set of programs defined at design time and stored in memory. Which makes a system dedicated to a specific function, within a more extensive system. It is a low-power Microcontroller/Microprocessor based computer system, which dedicated to providing specific functionality.

Defination of Internet or simply "the Net" is a worldwide "network of networks". This was the next step of ARPANET and NSFNET. The World Wide Web (www) or called "the Web" is the information-sharing model of the Internet. The internet can be defined as wired or wireless a decentralized network of over million of smaller heterogeneous networks consists of a set of national, regional and private. The internet is the common language whereby dissimilar computers with various operating systems, are able to communicate with each other, using a standard set of protocols.
