Everyone wants their internet network to be faster with a smooth flow of data. Internet is one of the basic needs nowadays and we expect it to respond quickly without any delay. But do we know what happens in the background when just type and hit enter? We notice the numbers such as 802.11, 54 Mbps in the specifications of a mobile or any network adapter. But do we really understand what it means exactly ? These are bandwidths of a network which determines the speed of a network.
These are the factors that we practically use to determine our network speed:
- Time taken to establish a new connection
- Time taken to load a webpage
- Capacity to stream any video
- Time taken to download any files
Bandwidth in a data network represents the rate of data transfer supported by any network interface.
It may refer to both the theoretical and actual output. Both are very different in real time. For instance, a standard wifi connection of type 802.11g theoretically provides a speed of 54 Mbps. But practically, the actual speed would be only 50% or less than that.
An Ethernet is capable of transferring 1000 Mbps, but they cannot be achieved reasonably. So why do network providers claim the theoretical speed and not the real time ? The difference between them is driven by few factors such as Network protocols, operating system and device hardware.
Broadband speed is the amount of data transferred through the network over a time. Measured as bits per second (bps). The effective data speed of any network is quite difficult to measure as it changes over time. The speed differs every second depending on the hardware we use, site traffic, file content, signal strength and congestion.
Going Into The Network:
While we surf the internet, we experience some delay in response for a new page. This is due to the latency in network. Latency is the interconnections between the origin of the web and the end user. A web page does not open as we type its address in a browser. It is more complicated than we can imagine. When we search for a web address, it has to find memory of the server and has to pass through few switches, access points, repeaters, routers and other hardware on the network. It is not the same case for each time we click a link. These packets of network differs from what we chose on the web page. The link you requested should repeat the interconnection for every response.
For example: If you type www.techtid.com your network may have to undergo the request for the website through atleast 20 intermediate connections. Every intermediate does not have the same speed as mentioned by your network provider. These loops are not considered while we surf the internet, but they play a part in it.
