Network Devices -- Lesson 3 - Part 12

නෙට්වර්ක් Bridge | Network bridge

නෙට්වර්ක් Bridge එක කියන්නේ දැනට අපි භාවිතා කරන Router එක වෙනුවට අපි ඉස්සර භාවිතා කරපු උපකරණයක්.Bridge එකෙන් වෙන්නේ වෙනස් නෙට්වර්ක්(LAN ) (Different network) එකට සම්බන්ධ කිරීමේ උපකරණයක් විධියටයි..

Network bridge is used to connect two or more diferent LAN network together..

Network Devices -- Lesson 1 - Part 10

හොඳයි එහෙනම් අද ඉඳන් මං මේ blog  එක සිංහලෙනුත් Update  කරන්න හිතුවා .. අපේ කට්ටියට තවත් ටිකක් පැහැදිලි කරන්න හිතාගෙන තමයි මේ දේ කරන්න හිතුවේ..

From today onward  i'm gonna  post every lesson in Both English and Sinhala.. so you can understand easily about some hard lessons..

So, Today we are going to discuss about Network devices..there are few network devices are currently in use and some are not in use..but we have to discuss about old devices too.

ඉතින් අපි අද පටන් ගන්න පාඩම තමයි.. නෙට්ව්‍ර්ක් උපකරන...  මේක යටතේ අපිට සාකච්චා කරන උපකරන කීපයක්ම තියනවා ..ඉතින් ඒ අතරින් සමහරක් දැන් භාවිතා වෙන්නේ නෑ.. නමුත් අපි ඒ උපකරන ගැන දැන ගන්න එක අපිට ප්‍රයෝජනවත්.. ඉතින් එහනම් අපි අපේ පලවෙනි උපකරණය ගැන  ඉගෙනගමු..

Network Cabling Lesson 3 -- ( Part 9 )

(කමෙන්ට් එකක් දාලා යන්න පුලුවන්නම් ගොඩාක් ස්තූතියි - If You can Post a comment , i'm very glad to you )

Today we are going to learn about Fiber Optic network cable.so pls note this is a very important lesson..even we do not use fiber optic  for common networking..it is the most fastest and most secure network cables..

 Mainly we can divide Fiber optic cables in to three catagories according to data transfer method..

1) Multi Mode step index

Network Cabling Lesson 2 -- ( Part 8 )

Coaxial Cables 

Here is our second lesson about network cabling.in this tutorial we are discussing abut Coaxial Cables.., Coaxial Cables are now not in use of computer Networks.However we discuss some important things about Coaxial Cables

Coaxial Cable

There are  Two types of coaxial cables

Network Cabling Lesson 1 -- ( Part 7 )

Cable

We are using several cables for Computer Networking, currently we use Fiber optic cable and twisted pair cables..coaxial cable are now ejected from networking ..

Just follow the following lessons about network cable..

First One is Twisted pair

Scope Of Computer Networks -- ( Part 6 )

Computer Networks are mainly categorized to two scopes according to its geographical size or the Distance between users.. so main scopes are

1) LAN ( local area network )

2) WAN ( wide area network )

Types Of Computer Networks -- ( part 5 )

There are two types of computer Networks

1) Client Server Network

2) Peer To Peer Network

...

Roles Of computers In a Network -- ( Part 4 )

Roles of Computers In a Network

1) Clients
2) Server

....

Minimum Requirment to setup a network -- ( Part 3)

To setup a network, at least we need  following requirments

1) Two Computers with Require hardware resources

2) Network Card

3) Network Cables with  connectors

4) Network Support Operating System ( Network cannot be run on 

     MS-Dos )

5) Network Protocol ( TCP/IP ) .....

 

Structure of a network -- ( Part 2)

 This is just for your attention ,not a lesson..just remember what are main part of a domain.. 

Introduction of Computer network -- ( Part 1)

What is a Computer Network ? 

" When we connect two or more computers together , we call it as computer network, the main purpose of having computer network is to share the resources and information... "

Advantages of  Computer Network
