LAN – The Local Area Network and General Introduction



Everyday all of us sit on our computers and are connected with the internet by means of our Ethernet cables, when we need to print our files from feet away we are able to do it and we’re even able to share big files from one computer to the other in our homes. Multiplayer gaming within the same house is also possible. But have you ever wondered how it happens? The only reason behind is local area network also known as the LAN. A local area network (LAN) supplies networking capacity to a gathering of different computers in closeness to each other, for example, in an office building, a school, or a home. LANs are worked to empower sharing of assets – like music, printers, recreations or different applications – and administrations – like email or Internet access. Best part is that these networks can either be alone or they can be connected to the WAN that gives them all internet access.

The structure

The era we are living in are dominated by networking and generally, the networks are using Wi-Fi or Ethernet for connecting tons of devices together and forming a web within a web. If we talk about the Wi-Fi LAN then it is in the air and is spread all over with the help of different access points. These access points work like bus stops and manage all of the traffic and its flow like a signal.

As far as the traditional wired LAN is concerned it uses different switches and routers also some hubs and other devices to connect the systems to a single network. So both Wi-Fi and Ethernet help the devices connect with each other without using any link in the middle that makes the operation very quick and uninterrupted. IP, also known as the internet protocol is the most dominant form of the protocol used on the LANs.

LAN, being vast

            A local network can contain anywhere in the range of maybe a couple gadgets up to a huge number. A few gadgets like servers and printers remain forever connected with the LAN while cell phones like smart phones telephones may join and leave the network at different circumstances. Both the innovations used to manufacture a LAN and furthermore its motivation decides its physical size. Wi-Fi local networks, for instance, have a tendency to be measured by the scope area of individual get to focuses, while Ethernet networks tend to traverse the separations that individual Ethernet links can cover. In both cases, however, LANs can be reached out to cover much bigger separations if necessary by totaling together various accesses points or switches.

Computer Network Speed, a general introduction

internet speed

Everyone likes it fast, today the life is moving ahead so fast that we hardly have a time to wait for something to load up for our operation. And when it comes to networking it always feels good finding out things to be very fast and totally operational but have you ever wondered what actually makes the network catch the speed? Together with fundamental usefulness and unwavering quality, the execution of a computer network decides its general convenience. Network speed includes a blend of interrelated components. So first of all the things that are going to pop up in your mind is going to be, what network speed is and how it works.

Defining Network Speed

Of course all of the users want their network to work flawlessly but many factors actually come into play that cause a little delay in the system and become a trouble for them. Sometimes this delay only lasts for a few milliseconds but in other cases it lasts for enough time to be a pain. The most usual kinds of issues we see include the time a new connection takes to establish, time to load a webpage, the most important time a download takes and last but not least the one we hate the most known as video streaming.


            Bandwidth is actually the main factor that decides the speed of the network. This bandwidth is visually represented in the transfer rate. Everyone knows the amount of bandwidth they are paying for when they subscribe for a specific service and get a router for the internet. Whereas in the networking it means the data rate supported by a network connection or an interface. So it’s just like a number that increases and also increases the speed of your network. Conventional Ethernet networks that hypothetically bolster 100 Mbps or 1000 Mbps of greatest data transfer capacity, don’t actually deliver it. This most extreme sum can’t sensibly be accomplished either. Cellular networks too by and large don’t guarantee any one particular data transfer capacity rating yet a similar guideline applies.

Scale to Measure Bandwidth

            The method of measuring bandwidth is simple, as it is the amount of data that passes through a network connection over time as measured in bits per second (bps). If you want to test the bandwidth speed you can always visit online websites that have tests and can tell you by giving a ping to your server. Indeed, even with these apparatuses available to you, bandwidth usage is hard to quantify definitely as it changes after some time contingent upon the design of equipment in addition to attributes of programming applications including how they are being utilized.


You might just consider one side of the coin and not the other, like it’s said both are important. That’s why bandwidth alone doesn’t put much role in the network’s speed but there’s also this one known as the ‘latency’. Bandwidth is only one component of what a man sees as the speed of a network. Latency is another component that adds to network speed. The term latency alludes to any of a few sorts of defers commonly brought about in handling of network information. A supposed low latency network association is one that encounters little defer times; while a high latency association experiences long postponements.

Scale to Measure Latency

There are different network tools like ping tests and trace route measure latency by deciding the time it takes a given network bundle to go from source to goal and back, the alleged round-outing time. Round-outing time is by all account not the only approach to quantify latency; however it is the most widely recognized.

So as a whole both factors play their roles in the network speed and to be honest, if you look around most of the users are only found to know about the bandwidth and not the latency that shows their lack of knowledge. Quality of Service (QoS) features of home and business networks are designed to help manage and give the users a better bandwidth and latency together to provide more consistent performance.

Ethernet cables and their differences



The world might be moving on to a wireless situation, where cables are much less in number. But the truth is sooner or later we all have to go back to basics and rely on them for our operations. One of these cables that are not going anywhere in the near future is the Ethernet cables. All of the Ethernet cables that we see around today have reached this point after an immense amount of change. They might look same from the outside but they have multiple functions at times from the inside and have classifications. However the only purpose of the Ethernet cable is to help in networking and connect devices generally to the internet. With so much variation in the market it can often get tough for someone to choose which Ethernet cable they must go with. Today we’d like to shed some light on these different types and also try to let you know which is going to be the best for the job.

First thing first, whenever you try to find out an Ethernet cable online there’s this one word you’re always going to find out as a prefix and that’s “Cat” e.g. the Cat6e, Cat-5. Have you ever wondered what this Cat is? Here is the ice breaker, it simply means Category. Whereas the digit that follows Cat is the representation of the specifications to which the cable was manufactured. If we try to make it easier for you then, higher the number, better the version and quicker the speed so here is the simple mathematics. More cables are being made for supporting higher bandwidth and increased speeds of downloads. What more could be kept in mind is the length of the cable. Usually the cables we use are below the barrier of 100 meters because above 100 meters the speed deterioration occurs.

So without wasting any more time, let’s get ourselves to the basic available and so far manufactured categories of Ethernet cables.

Cat3 and Cat5

Cat3 and Cat5 are currently being treated as dinosaurs in Jurrasic Park. You can only see them in the movies but they are, as we speak, extinct. You might not be able to find these cables in the market anymore as no one is manufacturing them. But just in case you get a chance to use them you might be reminded of Internet Explorer, because they’re too slow. Even the Internet Explorer doesn’t exist anymore. However later on the Cat5e was introduced down the line as well in which the letter ‘e’ was meant to be enhanced. The Cat5e is currently under use because it has no other physical difference than the Cat5 but is somewhat a better version.

Cat6 and Cat6a

As you can so far notice that the categories are being joined with digits and other alphabets. Here ‘a’ means “Augmented.” And yes! Just like Cat5, the Cat6 also exists. But the Cat6a cable has the ability to support twice the bandwidth than the earlier. They also have an astonishing ability to maintain the transmission speeds and are equipped with extra layers that can eliminate the crosstalk. These cables are always shielded.



Cat7 right now in the world is just like the iPhone 7. It’s the new thing in town, it’s widely available and right now, as we speak, it supports the highest bandwidths. Since it’s the latest version so it’s obvious, it’s faster than Cat6a. Although these cables are more expensive than the one’s explained earlier but their performance is going to define their price tag. These cables have the ability to reach the speeds of 100gbps and they are a perfect choice if you’re looking to connect your modem with your pc. Cat 7 cables are always shielded too, and use a modified GigaGate45 connector, which is backwards compatible with regular Ethernet ports.


With the growing need of bandwidth the cables are getting advanced as well as this new giant is right now being developed. Cat8 is going to have faster speed than any other Ethernet cable known to date. It will set up some new standards that might be preceded by Cat9, who knows.


Your choice for a cable

Now we come back to the issue at hand that how do you decide which cable is going to fit perfectly for your need. Best way is to find a cable that is going to have some mercy on your wallet and is going to be enough to complete your need of bandwidth. But then next question rises, what is your need of bandwidth? If you need the cable for home usage, then what you usually consume, the Cat5e cable is going to be enough. If we talk about the routers that are being used in homes they rarely support better than Gigabit Ethernet, so there goes your need to put the Cat6 and Cat7 up for the job because using them is going to be a big question mark. Your pick if you’re looking for high performance should be max Cat5e, Cat6 can be useful too but then you must have the bandwidth to that level.
