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 ;

Boyer Moore String Search Algorithm

Boyer Moore String Search Algorithm Boyer-Moore string search algorithm was developed by Robert S. Boyer and J Strother Moore in 1977. Concept of Boyer-Moore Algorithm Scan From right to left Bad character rule Good Suffix shift rule There is a preprocess in this algorithm. It's create a table with last occurrence of  pattern characters Example :                  Pattern : a b a c a b                               0 1 2 3 4 5                                     Table Note: If character not in pattern ,                                                T[i] = -1 Look at the table and find the last occurrence  "a" ( T[i] ...

String Matching with Finite Automata

👉How it works????? ♦Each character in pattern has a state. ♦ Each match sends the automaton into a new state ♦If all the characters in the pattern has been matched, the     automaton enters the accepting state.  ♦Otherwise, the automaton will return to a suitable state according to the current state and the input  character such that this returned state reflects the maximum advantage we can take from the       previous 👉 P reprocessing of pattern lets try example.... pattern= "ababc" lets make state transition table 1)Get the alphabet of pattern    alphabet of pattern  ={a,b,c} 2)Get the length of the pattern=5 lets draw the table.    1) 2) consider pattern lets fill "s0" column a      →      a     its match so value = 1 a     →     b     its doesn't  m...

Types Of Computer Networking

Generally,network base on their  geographical span.It can be as small as distance between your mobile phone and its Bluetooth headphone and as large as the internet itself, covering the whole geographical world.  Personal Area Network A Personal Area Network (PAN) is smallest network which is very personal to a user. This may include Bluetooth enabled devices or infra-red enabled devices. PAN has connectivity range up to 10 meters. PAN may include wireless computer keyboard and mouse, Bluetooth enabled headphones, wireless printers, and TV remotes.  Local Area Network(LAN) A computer network spanned inside a building and operated under single administrative system is generally terned as . Local Area Network(LAN) .Usually, LAN covers an organization offices, schools, colleges or universities. Number of systems connected in LAN may vary from as least as two to as much as 16 million. LAN provides a useful way of ...
