Computer Networking Basic Component

-
Hi, friends my previous post I explained  the Basic networking lesson.In this lesson I'll hope to discuss about What are the basic components to computer networking.

 In this post I'll explain;

1.Why Computer Networking?
2.Networking Basic Components

 So first ,I have one question:Why Computer Networking.
       
 Computer networks help users on the network to share the resources and in communication. Can you imagine  a world now without emails, online newspapers, blogs, chat and the other services offered by the internet?

 I explain this one by one:

File Sharing:



Networking of computers helps the network users to share data files.


Hardware Sharing:


Users can share devices such as printers, scanners, CD-ROM drives, hard drives etc. Without computer networks, device sharing is not possible.






User communication:




Networks allow users to communicate using e-mail, newsgroups, and video conferencing etc.


So I think you got some idea Why computer Networking?


Next I hope to explain What are the basic components to computer networking:


• Transmission media 

• Connectors

• NIC (Network Interface Card) 

• Protocols

• Address 

• Hub / Switch 

• Modem 

• Router 


Transmission media:


Transmission media are the facilities used to interconnect computers in a network, Transmission media are sometimes called channels, links or lines.





Transmission media devide 2 main part:

1.Guided media

2.Unguided media


**Guided media(Cable)**

UTP Cable

Coaxial Cable

Fiber Optics

**Unguided media(Wireless)**

Wifi

Microwave

Wimax


       My another post I'll explain this topics                                                                


Hub:


Hub is a device that splits a network connection into multiple computers. It is like a distribution center. When a computer requests information from a network or a specific computer, it sends the request to the hub through a cable. The hub will receive the request and transmit it to the entire network. Each computer in the network should then figure out whether the broadcast data is for them or not.





Switch:


Switch is a telecommunication device grouped as one of computer network components. Switch is like a Hub but built in with advanced features. It uses physical device addresses in each incoming messages so that it can deliver the message to the right destination or port.



Routers:


A route is device that forward data packets between computers.


Routers can be devide 3 main parts


1.ADSL Routers

2.3G / 4G Routers

3.Wireless / wifi Routers


1. ADSL Routers(A Digital Subscriber Line)


       This Routers call "Broadband".This Routers connect to Internet using Telephone.




2. 3G/ 4G Routers


This Routers connect to Internet using Computers.






3. Wireless/Wifi Routers


Wireless Router is a device without cables.






My another post I'll explain IP addressing in Computer Networking

THANK YOU ;

KMP String Matching Algorithm What is the meaning of KMP? KMP  -  Knuth - Morris - Pratt  History of KMP string matching algorithm The algorithm was conceived inn 1970 by Donald Knuth and Vaughan Pratt and independently by James H. Morris. The three published it jointly in 1977. Before learn about KMP algorithm there are two things to learn,                      1. Prefix                       A string ω is a prefix of a string x, denoted w ⊏  x,                           if x =  ωy for some string y € Σ* and                            | ω | <= |x|                           e.g. ab ⊏ abcca             2. Suffix                     A string ω is a suffix of a string x, denoted ω⊐ x,                           if x = yω for some string y € Σ* and                           |ω| <= |x|                           e.g. cca ⊐ abcca Note: The empty string ε is both a suffix and a prefix of every string. Let's move to algorithm, KMP requi

  Climate change is no longer a distant threat; it's here, and it's affecting our planet in ways we can no longer ignore. As temperatures rise, natural disasters become more severe, and ecosystems collapse, it's crucial that we take action to address this global challenge. Fortunately, there is hope. By adopting sustainable practices and reducing our carbon footprint, we can work together to create a healthier planet for ourselves and future generations. In this blog post, we'll explore the ways in which climate change is impacting our world and the solutions we can adopt to address it. From reducing our reliance on fossil fuels to promoting eco-friendly products and practices, we'll examine how we can work together to build a more sustainable future. We'll also dive into some of the most promising developments in sustainable technology, such as renewable energy sources like solar and wind power, energy-efficient buildings, and sustainable transportation solutio
