Definition: A Scheduling Algorithm is the algorithm which tells us how much CPU time we can allocate to the processes.
These scheduling algorithms are either preemptive or non-preemptive.
Preemptive Scheduling Algorithms are those which are based on the priority of the processes. By preference, when a high priority process enters, it preempts a low priority process in between and executes the high priority process first.
Non-preemptive Scheduling Algorithms are those who can’t be preempted in between, i.e. we can not take control of CPU in between until the current process completes its execution.

Definition: System Software can be designed as the software in such a way so that it can control and work with computer hardware. It acts as an interface between the device and the end user.

Definition: Memory segmentation is the process in which we divide the primary memory of the computer into segments. It is a memory management technique. Each segment can be allocated to a process.
The segment table is the table which stores all the details about the segments which are further stored in one of the segments. Segment table contains two information about the segment: one is, the base address of the segment and other is, the length of the segment.

The operating system provides set functions to create, synchronize, control, execute the processes on the system. In the earlier time when the operating system was not available then every program required full hardware access or time for execution. To overcome this problem and used the CPU efficiently, the operating system introduced.

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.

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.
