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.

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.

• Switched-Mode Power Supply (SMPS) is an electronic circuit which converts the power using switching devices that are turned on and off at high frequencies, and storage components such as indicators or capacitors to supply power when the switching device is in its non-conduction state. It can be abbreviated as SMPS.
• The switched-mode power supply is also called switch-mode power supply or switching-mode power supply. Its efficiency is high. That’s why we use it in the variety of electronic types of equipment which require a stable and efficient power supply.

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.
