What mean of network
How does it work
Hub,switch,router.
Classifying network
Proxy,ip subnet ,dns

Computer Networking
The computer networking is a group of interconnected

(network capable devices)
Components network,interface card, hubs,switchs
,Routers.cable like cat 6,cat 5

How it network work,
What is communicated
When is it communicated
How it communicated

Example : Talking ,torch light communication
We need a protocol : we set rules gove rning data communication
Tcp/ip is such a protocol

Basic Require hardware components
network interface card (nic)
hub
switch
router
cable

Frist i tell me What a interface card
this card allows a network capable device access
to a computer network such as the internet

the Mac address identifies the vendor and the serial
number of the Nic which is the
unique to the card

I tell u what is hub
a network hub or repeater hub is a device
for connecting multiple
twisted pair or fiber optic ethernet devices
together.

when a packet arrives at one port,it is copied to
all the port.it is copied to all the ports of the hub
for transmission

Switch

Switch

The switch is a devices that performs that
performs
It forwards and filters datagrams

(chunk of data communication )
Between ports based on the mac-address in the packets

Router

Forward data packets
between networks
using headers and forwarding
tables to determine the best path to
forward the packets,

Processor,Os , Memory

Cables

Category 5 Cable ,Known as cat 5 or

Cable and Telephone is a twisted pair cable (100mbs)

A optical fiber is a glass
plastic fiber that
carries light along its length

(40gbps)

8 pair usage for data in Cat 6 Wire in Networking

Today I Post the Cat6 wire pair use in Networking ,we all know 8 pair in cat 6 and but no idea how any pair use in Networking .only 4 pair Use in networking , Like this Photo, If 4 pair not work in cat6 wire we use another 4 Pair same wire Save time and Money

Tech Purchase Decision Making

Research Methods for Finding Reliable Product Reviews Start with professional tech review sites like TechRadar, GSMArena, and The Verge for comprehensive tech product analysis. These platforms maintain editorial standards and often conduct hands-on testing before publishing reviews. YouTube channels from established tech reviewers offer visual unboxing videos and real-world usage demonstrations that reveal details traditional written reviews might miss. Cross-reference multiple sources to get a balanced perspective. Reddit communities like r/Android, r/technology, and product-specific subreddits provide unfiltered user experiences. Amazon verified purchase reviews help identify common issues, but focus on detailed reviews rather than single-sentence ratings. Check manufacturer forums and official support pages to understand known issues and firmware update histories. Professional review aggregators like Metacritic compile scores from multiple sources, giving you a consolidated vi...

OSI MODEL (Open Systems Interconnection model )

To Day I Explain OSI MODEL, Open Systems Interconnection model ( OSI ) is a conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into abstraction layers. The model is a product of the Open Systems Interconnection project at the International Organization for Standardization (ISO), maintained by the identification ISO/IEC 7498-1. The model groups communication functions into seven logical layers. A layer serves the layer above it and is served by the layer below it. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer. The Below Shown Diagram is helpful to understand the OSI seven Layer Model. OSI MODEL EXPLANATION Th...
