OSI Model  (Open System interconnection) Hii , i am Vasu Birla and today we discuss about OSI Model, a very popular term often used in the Networking. So  What is OSI model and why it is needed  So pahle History pad lete he ,,, History of Osi -   In the 1977, ISO (International Standard Organization) made a committee for Develop a Open standard for Interconnection between the all kind of electronic devices  after that Later in 1984 ISO's committee introduce a OSI model ( Open System Interconnection Model). What does mean by OPEN   - In OSI (Open system interconnection ),,, Here Open means ,, whomever follow this Model  means  vendors , Manufactures ( IBM,apple,Microsoft, Intel )   jo bhi ho ,, if they follow this model for manufacture computer systems so, Those devices, systems can communicate to each other  whether that are from same vendor or from different Manufacturer . ( matlab yadi ye companies OSI ko follow karke apne syste...

hello friends this is Vasu Birla ,, and today we will discuss about third method of classification of Networks . 3. Network Topologies     What is Topology ? Topology mean How devices connected to each other and how they transmit data in network .. .. Ther are Two kind of ToPoloty ..  i.  Physical Topology.   It means actual layout of the computer , cables and other devices ,,, simply how devices are looking physically,. that is Physical Toplology. ( Jo Actual dikh raha he human eyes se wo physical topology he). Note:-  It does not sence how they look physical ,,but it matters that how they work logically ,, so  logical topology is important   ii.  Logical Topology.   It Means How devices data transfer the data in the network ,,or how they work ,, For example   Hub ,,   Hub is centralize device  ,,they are looking like a Star Topology (jab use apni aakho se dekhoge to star topology d...

Hello once again ,, i am Vasu Birla ,, and today we will discuss about second method of classification of Network . 2. Area of networks. .. according to this method Network are classified in following  types  PAN- personal area network LAN - Local area network   MAN- Metropolitan area network  WAN - Wide area network    (i)..PAN - personal area network-   It is a Small computer network.  This network in used within 10 meter of area only. it include wired and wireless medium,, example ,, Two pc cab be connected directly by single cable  and fax machines , printers , Telephones  and in wireless  Bluetooth is the best example for PAN.  (Wireless headphone, wireless keyboard, Mouse) PAN     (ii)..LAN - Local area network-    It is a network which is used for small area around 100 meter  like small office , Home, building and school ,,but it can be extended after 100 meter...

I am vasu birla  and once again i am going to discuss on some terms of Networking ,, In the Last Part we knew about the Types of Network according to diffrent methods so the first method is Network Design. 1. Network Design.,   according to this method Network are classified in two types  (i)..Peer to Peer Network  (ii).. Client - Server Network    Before we talk about it ,, i am going to discuss some terms which are Server and clients Server - Server is a computer which act as a service provider . if we give some specific roles to any  computer . that computer perform that roles ,.,, for example if install printer server in a computer so that computer will act as a Printer server. Client.-   Second type of computer are clients ,, which act as a Service requester in a network. for example if you use your computer and access Google.com  so at that type your computer is client or service requester.  (i)..Peer to Peer...

CCNA full training and knowledge in hindi and simple english language. TYPES OF NETWORKs So we can classified Network by many Methods here are these methods.  hum  ye sabhi types agle parts me discuss karege. 1. Network Design-   client server and peer to peer Network     2.Area of Networks Lan, Wan , Pan , SAN    3.Network Topology  Bus ,Ring ,Star,  mesh ,Hybrid    We will discuss these methods in next parts

hello friends ,my name is Vasu Birla from Sanawad ..and i have decided to start a blog for Computer Lovers specially for those students who are interested in Networking and small tricks of computer which made you confident and valuable. To me har chiz shuru se ek dum basic level se start karuga Networking me CCNA matlab cisco devices and MCSE matlab Windows servers ka full knowledge lene wale he ,, i am not proffesor but i make ensure you that my every content will make you knowledgeable. First of all sabse pahle hume Networks ke bare me padna he to first question is .. What is Network ??  Networks means interconnections means when things are connected to each other that is Network. Whether it is of People or things or equipments.  What is Computer Networking ? In a Information Technology , Points or Devices or Computers which are Connected to each other by any communication paths are may be wired o r wireless .  Computer Network is collection of hardware ...

MCSE vs CCNA - Which is better Certification ? Types of Computer Network Certifications Network Certifications To become a computer professional, expertise is the highest requirement that must be achieved. This comes from years of practice and study. Indeed, one should not even pursue a computer technology career unless one is willing to study and study and study. Computer technology changes every few years and that means that in order to keep up with the changes, one must delve into the topic or topics. For instance, the Internet only became popular in the early 90's. Not everyone jumped on the band wagon. Even Bill Gates decided to move Microsoft from a software company, to an Internet company.
