Local Area Network

Bandwidth is measured in bits eg Gigabits (Gb) Megabits Mb not to be confused with Gigabytes as in "how many Gigabytes of RAM/Hard Drive space does your computer have?"

When abbreviated gigabits is Gb (with the "b" as a lower case) vs. Gigabytes which uses a capital B in the abbreviation

The difference is important because there are 8 bits in a byte so mixing the two up tends to throw off one's calculations.

Anyways back to the topic on hand, there are MANY different types of fiber data cables with various bandwidths, such as ones you would find in a datacenter, some server setups, or connecting a number of switches in a large network.

4Gbit/sec & 8Gbit/sec are fairly commonplace though 10Gbit/sec is becoming more and more widely used.

there are also OC connections (from OC 1 or 2 or 12 all the way to OC -768 which is upwards of 38 Gbit/sec and generally only used as the backbone of large enterprise networks)

Then there are the cables that run under the ocean and connect continents (theres over 176 of these)

Now these cables have many, many individual fiber optic strands in them and have bandwidth of hundreds or thousands of Gbits/seccond

I also have some older 24 and 36 port switches kicking around that have 1 Gigabit fiber connectors, however that is the standard these days for desktop and laptop computers (for wired, not wifi) although thats using the copper wire Cat-5 or Cat-5 cables which are much cheaper so the 1Gbit fiber is obselete unless you're trying to use it for long distances, as fiber optic cables -transmitter depending- have much less attenuation (signal degridation) than copper and transmitter depending can go through cables that are several kilometers long without needing a repeater.

Hope this helps

The OSI model is a simple framework for categorizing the different layers that make up network communication. There is no direct relation between the OSI model and any network address or protocol.

In fact, most network protocols don't fit neatly in to the OSI model. TCP/IP, for example, spans the data-link, network, and transport layers.

when you are connecting same devices like computer to computer or switch to switch or router to router to use cross over cable.

Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1.

Yes it is.

A hybrid is a combination of two or more basic network topologies, such as a star-bus, star-ring, or tiered topology.

It is desirable in some cases where the time to establish and maintain a connection is either unnecessary or incurs excessive overhead.

Take, for instance, beacons broadcast by either your cellular towers or WiFi access points--these transmissions are multicast and are not intended for a particular recipient, thus there is no reason to set up a connection to any client devices. Any multicast transmission would not need to establish a connection.

In other cases, such as streaming video applications, a connectionless protocol like UDP is used since lost packets are often unusable once they fail to reach the recipient by a given deadline. An application using UDP transport will be able to ignore the lost packets or explicitly request important packets again, whereas a connection-oriented transport layer like TCP would retransmit stale packets and also throttle bandwidth in response to lost packets.

A classful class B network has a network range of 128 - 191. For host addresses, anything that is legal for an IP address in the last 2 octets would be a valid host address for a class B with no subnets.

Well Port Forwarding is really only, opening ports and making them special to let a one connection on it. The main purpose for me is for gaming, you need to port forward for a game to run a dedicated server if the game allows, like Quake 3 arena, or GTA's, or Call of Duty's ect.

The basic idea of using a network is to share resources; therefore, by its very definition you are using a form of distributed processing. There is no way around that, because when you share resources you are distributing the information, this way across a network.

Routers perform DHCP, which means the router acts as the "owner" of the network. If a router set it's own IP address to 192.168.1.1, then it will likely assign IPs to computers connected to it in the 192.168.1.x range. If you plug another router into your first router, the second router might have the IP 192.168.2.1, and then assign IPs in the 192.168.2.x range. This is what you want to avoid. Having all your computers on the same 192.168.x network is necessary.

You essentially want to use your second router as a switch. To do this, disable DHCP in the routers admin UI. Then, instead of plugging the source cable (coming from your first router) in the "Uplink" port, plug it into one of the regular 1, 2, 3, 4 etc ports. This will enable your router to pass along IPs from your main router, rather than assign it's own. Plug other devices into 2, 3, 4, etc. You've essentially bridged your routers.

LAN users get access to internet or can communicate with others LAN connected to WAN.
