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 sharing the resources between end users. The resources such as printers, file servers, scanners, and internet are easily sharable among computers. 




Metropolitan Area Network(MAN)



The Metropolitan Area Network (MAN) generally expands throughout a city such as cable TV network. It can be in the form of Ethernet, Token-ring, ATM, or Fiber Distributed Data Interface (FDDI). Metro Ethernet is a service which is provided by ISPs. This service enables its users to expand their Local Area Networks. For example, MAN can help an organization to connect all of its offices in a city.






Wide Area Network(WAN)




As the name suggests, the Wide Area Network (WAN) covers a wide area which may span across provinces and even a whole country. Generally, telecommunication networks are Wide Area Network. These networks provide connectivity to MANs and LANs. Since they are equipped with very high speed backbone, WANs use very expensive network equipment. 







WAN may use advanced technologies such as Asynchronous Transfer Mode (ATM), Frame Relay, and Synchronous Optical Network (SONET). WAN may be managed by multiple administration





My next post ,I will hope to discuss "What are the basic components to computer networking"

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...
