What is Operating System


What is an operating system? Now, this is a starting point for anyone who needs to study operating systems.

This is the most basic question that will come to your mind. So let's deal with this question. First in this Artical

We will discuss two topics to understand what is an operating system. First, we will have a look at the definition of an operating system, and we'll try to understand its meaning as well.

List in the second topic, we will see where exactly an operating system fits in the overall computer system.

This will help us understand the role played by an operating system in the functioning of a computer.

1. Definition of Operating System

Whenever you switch on your laptop, desktop tablet, or even a mobile phone, you might have observed that it takes some time to load your home screen here.



Your device is starting the software in the background, and this software will help you control your computer or mobile device and lets you run other applications on top of it.

This software will be running as long as your devices are running. And it stops only when your device shuts down. If you are even remotely a tech savvy person, he will know what this software.

It is an operating system to define it. Formally an operating system is an important piece of program that manages the computer hardware and other software applications.

Using an operating system, you can utilize the hardware components like CPU, memory input, and output devices like keyboard mouse, et cetera.

So therefore an operating system also acts as an intermediate between the computer hardware and you, the computer user. 

You can see it acts as a middleman. This is because the user can not give commands directly to the CPU in machine language, Narcan, the CPU interact with the user directly.

So there needs to be a middleman which communicates and translates all interactions between the user and the CPU. 

2. What is Operating System

Now let's see where exactly the operating system fits in the world. Computer system structure a computer can be divided into four components.

At the core, we have the hardware which comprises of CPU, memory, and other IOS devices.

On top of this, there is an operating system which controls and coordinates the use of hardware by various applications.



Application programs are the software tools or utilities, which the users to carry out their tasks. These programs can utilize the hardware resources through the help of operating systems.

Examples

Some examples of application programs are the word processors, spreadsheets, compilers, and even the browser. 

And finally, on the other end, we have the real computer users who interact with the computer in order to get some tasks performed.

So based on this figure here, you can see that the operating system occupies a crucial spot in the architecture of a computer system and without operating systems, it would be very difficult to utilize the computer effectively.

So that should give you a basic idea about what is an operating system. If you still have any queries posted

What is Pic18-Q40 Microcontrollers  The pic18-Q40 family of microcontrollers combined powerful, versatile, and highly configurable core independent peripherals with advanced interconnection capabilities. These device family offers high level of sophistication into a small 14 or 20 pin space saving packages as a small as three by three millimeter. This product timely offers opposites 64 kilobyte up onto flash memory up to four kilobytes SRAM and 512 bytes up E prom system clock is speed up, up to 64 megahertz across there. 1.8 to 5.5 bolt operating voltage rains in temperatures from negative 40 to 125 degrees Celsius. What is Cache Memory Concept os Loop mesh node branch What is System in Chip What is Multiviblator Also, when you need a par savings, these devices can operate in idle, standby and power down sleep modes to balance performance with power consumption. The pic18-Q40 device family is smallest Pic. Pic18 microcontrollers ever built is suitable for a variety of applicati...

What is Random access memory (RAM)

What is What is Random Access Memory (RAM) Random access memory (RAM) has two defining traits. First, you can jump around in the memory space using addresses.  You can write new data up here at address 1,000,024, and then you can send a new address command and immediately read what is down here and address 88. You can also pick any starting address and then read or write sequentially from that point stop when you want and jump to a different spot and do it again. The second trait of random access is that writing new data into a certain address can be done just as quickly as reading the data from that address.  In other words, from the microprocessor or microcontrollers perspective, the timing to erase and overwrite is the same as the timing to just read the data at any address, we call this trait symmetrical read and write in NAND and nor flash memories, E prompts, which are not random access memories. The physics of erasing and writing over the last content can take lots of t...

What is Two Port Network

Image
So in this Artical, we will learn about the Two Port Network . So as its name suggests that two port network is the electrical circuit or the network, which contains the two ports. But to understand it in detail, first of all, we need to understand  What is Port What is port ? So the port is the pair of terminals, which connects the electrical circuit or the network to the external circuit. So through this port, any actual network or any independent source can be connected to the existing network, but any two terminals cannot be called as a port. And for that, they need to satisfy port condition if the current I, and to the one terminal of the port and the same current should lead to the second terminal. So if the pair of terminals satisfy this condition, then they can be called as a port. so if the electrical circuit or the network contains one such port, then it is called the one port network and all the basic circuit elements like the aesistor capacitor and the data out of the e...
