What you’ve found here is the start of a replacement group of Articles designed to assist you to understand the foundations of Networking. If you’re new networking or studying for a certification like CCNA, Network +, or JN CIA this is often an excellent place to start. For a couple of articles, I’m getting to assume that you simply haven’t any networking experience. My goal is to make a solid foundation for you to create. During this article, we’re getting to start with understanding what a network is and a few of the network types, you will see. We’ll follow-up on part two with a glance at how a network could also be cabled and obtain a summary of addresses.
What’s a Network?
So maybe you already know what a network is. Maybe you’ve built your network reception or help someone to run the network at college or your job. That’s okay I do not want to bore you so if this applies to you, I might wish to offer you
this challenge stop reading the article and consider an honest description of what a network is that if you’ve come up with something you’re proud of well-done be happy to skip ahead otherwise stick with me and I’ll see if I can come up with something for you at work or home you’ve got a bunch of devices computers printers TVs then on you connect these employing a network when the devices are connected
they’re ready to share data this might be sending a print job to a printer sending an email or streaming video this will even be used for sharing an online connection mostly network users are unaware of the network they’re using as a long as they will browse the web do their job
browse Enagest.com they’re usually fine for all of those devices to speak they got to be connected somehow one-way sir plug cables into the devices and connect them to a different device called a switch example is during a school’s computer lab during this case a computer within the lab connects to a wall socket with a cable another cable runs through the wall which comes out at a
patch panel this might be during a cabinet on the wall somewhere within the room or another room entirely the port on the patch panel then connects to the switch
you might have a switch reception too most homes do not have wall sockets so devices are connected to the switch we’ll talk more about how switches work
later we will also connect devices wirelessly a standard thanks to doing that is to use wireless accesses point a wireless network like this is often also called Wi-Fi
an example of this is often if you’ve got a tablet it’s impractical to cable it in so Wireless may be a good option the access point is a sort of switch without cables
more than one device can hook them up with the access point over time but without the messy cabling the access point also can be connected to the switch with a cable this manner wired and wireless devices can all be a part of an equivalent network having both wired switches and wires access points gives you more connection options imagine you’ve got a laptop in an office you’ll connect it to the network with a
cable once you’re at your desk when you have a gathering within the room, you remove the cable and hook the up with Wi-Fi where the wired or wireless the goal of the network is to maneuver information from one device to a difference for this to figure the sender and therefore, the receiver must understand one another they
need to speak an equivalent language within the network speaking the equivalent language means that devices agree on how data is shipped received organized and handled they agree on a process that all of them follow it is a bit like filling out paperwork this is often called a protocol ton of various protocols are used counting on what’s needed at the time network software and hardware are
designed with these protocols in mind you’ll hear of protocols like Ethernet and TCP which are used for sending and receiving data you’ll also hear of
protocols like HTTP which is employed for accessing the online and SMTP which is employed for usually email several protocols are won’t together to realize a task we glance at protocols further in future article in summary networks are used to connect devices use the network
to communicate and to share information devices got to speak an equivalent language this language has named a protocol which may be a set of instructions of the way to handle the knowledge.
we’re getting to start with some simple inquiries to get the brain working
firstly what are the 2 ways computers can hook up with the network to follow on from that what devices do they typically hook up with and eventually what percentage
protocols are used when one computer accesses another computer when you’re able to see the answers follow the link at rock bottom of the screen that works
connect devices you’ll call devices on the network nodes may include devices that help control the traffic flowing through a network like switches
and routers nodes also include endpoints or hosts these are devices that send and receive the majority of the traffic this includes workstations servers
printers Then, on now works are available different sizes a network reception is an example of a little network these networks usually only have a couple of nodes
this is called a Soho Network Soho means small office headquarters these networks typically have a couple of computers a printer a few phones and tablets some devices are going to be wireless, and a few are connected to a switch this could be a
good time to say that folks often say hub, once they mean, switch you’ll see why in fact, because the switch seems like a central hub during a Soho Network but
please confine mind that switches and hubs are very various things hubs are ancient technology that you simply generally don’t see any more outside a museum while switches are modern and commonly used they appear very similar so it is easy to combine them up to possess a glance at the model number to ascertain if it gives, you any clues about what the device is during a Soho Network a router is employed to
connect to the web you would possibly find that the router switch access point are all integrated into one device also her network will only have a couple of devices an organization for instance the bank will have many devices this is often called an enterprise network the enterprise network may cover several floors during a building there can also have
several office buildings in several cities or maybe across different countries an online provider features a very large network this is often called a
service provider network not only do they supply Internet access they also offer services to attach their customers consider the bank with offices all around the country the service provider uses a part of “Sgt; a part of their network to hitch these officers together when devices are collected into an area we call this an area network or LAN the land could also be a little network during a Soho Network the LAN is the switch with the few devices connected or the land could also be part of a much bigger network like an enterprise network this network may have many switches routers and access points counting on their needs
think of the bank from before they need an office with several floors you’ll consider the entire building as a LAN or more likely the network is choppy
into smaller parts perhaps, there’s a separate network on each floor each of these could even be called the LAN these separate LANs could also be connected, but we’ll talk more than later but a banks network is going to be larger than simply one building bank has offices everywhere the country and everyone over the planet albeit they’re far apart these networks are often joined together this is often called a win or wide area network imagine for a flash that you’re employed for a corporation with an office in Sydney and an office in Melbourne you
could contact a service provider, and that they can connect these officers for you where’s there a subject all of there, so we’ll cover them intimately during a later
video let’s take a flash for a fast summary all networks are different and this
includes their size a Soho Network is tiny, while an enterprise network, could also be very large your network could fit.
in anywhere in between a LAN or local area network, may be a collection of network devices during a local area sort of single building a when or wide area network
connects networks that are far apart and once more it is time to urge the brain.
working here’s something to believe your work for a corporation that features a
finance division an engineering division and admin division each group has their network and therefore, the networks are joined together during this network still a LAN or is it something else entirely the corporate growth and adds a retail division?
in addition to the top, office, there are now six branches offices what sort of network is that this as before getting to the link below to ascertain the answers?
I hope you’ve enjoyed part one among this series join me partially two where we’ll have a glance at differing types of cabling the Ethernet protocol and a touch of an introduction into a network addressing if you found this useful share and click on the likes of a button.
