0:34 now let's get into it Network topologies
0:36 describe the arrangement of devices like
0:39 computers printers and servers in a
0:42 network it determines how data flows
0:45 between these devices and how reliable
0:48 or scalable the network can be choosing
0:50 the right topology for your network can
0:52 make all the difference in performance and
0:53 and
0:56 flexibility today we'll cover the most
0:59 common types of network topologies bus
1:03 star ring mesh and hybrid let's start
1:07 with the simplest one bus
1:10 topology in a bus topology all devices
1:13 are connected to a single Central cable
1:16 called the bus think of it like a single
1:19 Highway where every car each device
1:23 travels along the same route it's simple
1:25 cost-effective and easy to set up
1:27 especially for small
1:29 networks however the downside is that
1:31 that if there's too much traffic meaning
1:33 too many devices trying to send data at
1:36 once collisions can happen which slows
1:40 down the entire network and if the main
1:44 bus fails the entire network goes
1:47 down next up is the star topology in
1:50 this setup all devices are connected to
1:52 a central Hub which acts as the traffic
1:55 controller if you imagine the central
1:58 Hub as a roundabout and each device as a
2:01 road The Hub Direct data between the
2:04 devices this topology is great because
2:06 if one device fails the rest of the
2:09 network isn't affected but if the
2:12 central hub goes down the entire network
2:16 stops star topology is commonly used in
2:18 offices or homes because it's easy to
2:20 manage and
2:23 expand now let's take a look at the ring
2:26 topology in this setup each device is
2:28 connected to exactly two others forming
2:32 a continuous loop or ring data Flows In
2:34 One Direction around the ring traveling
2:36 from one device to the next until it
2:39 reaches its destination while this
2:41 topology can be more reliable than bus
2:44 topology it has a critical flaw if one
2:47 connection breaks the entire network is
2:50 affected it's efficient for smaller
2:52 networks but isn't very common for
2:54 larger more modern
2:57 networks a mesh topology offers the
3:00 highest level of reliability because
3:02 each device is connected to every other
3:04 device in the network this creates
3:07 multiple paths for data to travel so if
3:09 one connection fails data can still find
3:11 its way to the destination through a
3:15 different route imagine a city grid
3:16 where every street connects to every
3:19 other Street giving you endless ways to
3:22 get from one point to another mesh
3:24 topologies are often used in critical
3:27 environments where reliability is key
3:30 like in military or Hospital Networks
3:33 however it's expensive and complex to
3:36 install due to the sheer number of
3:39 connections finally we have the hybrid
3:41 topology which is a combination of two
3:44 or more different topologies like a mix
3:47 of star and bus topologies this allows
3:49 networks to take advantage of the
3:51 strength of multiple topologies for
3:53 example a large business might use a
3:55 start topology for one department and a
3:58 mesh topology for another hybrid
4:00 topologies are flexible and scalable
4:02 making them perfect for growing networks
4:05 that need to adapt to changing
4:08 requirements so how do you decide which
4:11 topology is best for your network let's
4:13 look at a typical office the marketing
4:15 department might use a star topology
4:17 because it's easy to manage and allows
4:20 for simple expansion as new team members
4:23 join on the other hand the IT department
4:25 might use a mesh topology for its
4:28 servers ensuring that if one connection
4:30 goes down the other others can still
4:33 keep the system running smoothly
4:35 choosing the right topology depends on
4:37 the size of your network how critical
4:40 its uptime is and your
4:42 budget and that's a quick overview of
4:44 the most common Network
4:47 topologies each topology has its pros
4:49 and cons and the right choice depends on
4:52 the needs of your network whether it's
4:55 Simplicity with bus topology reliability
4:58 with mesh topology or a mix with hybrid topology
4:59 topology
