Computer Networks All Basic in one Blog :machinelearningtechnilesh

 . A computer network is formed by two or more devices connected together, these devices might be connected to share data to do some computations together or to share the resources. For example, a simple network where two computers are connected and one printer is connected and these both computers want to give command to the printer. So Resource Sharing is happening Do you do computer networks, computer networks are in fact everywhere they are in our office, they are in our home. In home, we might have multiple devices like laptops, Alexa, or other devices which are connected in a network. in office, you often see networks, your computers connected through a switch or any other device like router, and they form a network. So there are many, many networks that exist. In this course, we are going to focus mainly on internet, the largest network, almost half of the world's population is connected to the internet. In fact, most of our home devices, our office devices, they are connected to internet, how all this magic happens, you are here somewhere in your office or home and you can browse a website which is there in some other corner of the world.

This there are many many interesting challenges that arise when all this is happening.

The first issue is the first challenge

that arise when all this

this is happening.

The first issue is the first challenge is reliability, how to ensure that your request reaches the server reliably, and data that you receive from the server that comes to you reliably.

The next issue is scalability. Internet has been growing a lot over the years. Now how to ensure that all the devices stay connected they get all the services, every device has proper address, there are no address collisions.

allocation of bandwidth, how to ensure that there is no particular device a particular sub network which is consuming all of the bandwidth of the internet not allowing others to use it.

Security, how to ensure that your data reaches the server securely and usually get the data from server securely. Please note that these are only key challenges there exists many many other challenges which arise in internet.

Let us now talk about computer networks to carriers perspective.

What a student then it is one of the main subjects which is asked for higher study exams like gate or other government exams.

Also, if you are preparing for interviews, then it is the one of the main subjects which are asked in the interviews after data search algorithms DBMS and operating system

See there exists many sub

Computer Science which you study and not as an interview like compiler design rarely asked theory of automata aliens but this subject This is one of these objects which is

Austin computer interviews

if you are a working Professor

Till then it's a must must know subject. If you are an IT support. You must know how IP addressing work on suddenly

Due to our, our DHCP works, all these things you must be aware. Not only these things you should know all the details of computer networks to be a good IT Support Engineer

If you are an application developer and if you are building web applications

Network applications.

important to know The protocol

layer protocols like

TCP and UDP these things are must know if you are a web application or a network application. In the next video we are going to talk about computer net

Network models. We are going to talk about terms like protocols. Why?

Do we divide computer networks into different layers?

We are going to talk about
