Most hosting companies offer a variety of bandwidth options in their plans. So exactly what is meant by bandwidth katiannya with web hosting? Put simply, bandwidth is the amount of traffic that is allowed between web sites and other sites from the internet. The amount of bandwidth that can be given the hosting company is determined by their network connections, both for internal and external to the data center Internet public. But the bandwidth itself has a wide range of understanding (contextual), including:
Internet, quite simply is a group of millions of computers connected to the network. Connection may be large or small, depending on the wiring and equipment used in specific locations. The size of any existing network connection to determine how much bandwidth is available. For example, if you are using a DSL connection to connect to the internet, you have 1.54 Mega bits (Mb) of bandwidth, the bandwidth is measured in bits (a 0 or 1). Bits are grouped in bytes which form words, text, and other information that is transferred between computers and the internet.
If we use DSL to connect to the internet, we already have a dedicated bandwidth (dedicated) between a computer with internet. But ISPs you may have thousands of DSL connections to their location. All of these connections is connected to an ISP that uses a dedicated path through the well (or multiple connections) which is much larger than you gnakan. They must have enough bandwidth to serve the computing needs for all customers. So, even if you have a 1.54Mb connection to the internet provider, your ISP may have a 255Mb connection to the internet so it can accommodate your needs as well as 166 other users (255/1.54).
A very simple analogy for bandwidth in the context of the traffic is like a vehicle on the highway. Bandwidth is the width of the road and traffic is the number of vehicles. If we are the only riders on the highway, the trip can be reached very quickly. But if we get stuck in the middle jams, our journey may be very slow because of all the streets are also filled by another vehicle.
Traffic is the number of bits that are transferred on network connections. For simplicity I will give a small example, One Gigabyte = 2 to the power 30 (1,073,741,824) bytes. One GB = 1024 megabytes, let’s assume it takes one byte to store one character (for ease of analogy). Imagine 100 file kabisnet in a building, each cabinet there is a 1000 map. Each folder has 100 papers. Each paper contains 100 characters – 1 GB is all the characters in the building. A typically sized MP3 songs 4 MB, the same song in WAV format reaches 40MB, a complete full length reaches 800MB to 1000MB (1000MB = 1GB).
If we want to transfer this MP3 song from a Web site to the computer (download), we will create 4MB of traffic between a web site with a computer, depending on the network connection between the web and internet sites, the transfer may occur very quickly, or it could be very long if others are also downloading files at the same time
Bandwidth in Hosting
In the example above, we discussed traffic in terms of downloading an MP3 file. However, every time we visit a website, we will create traffic, because at the time of opening a site in which there are image files, flash animation, text, etc. will be downloaded before being displayed to the browser software (Mozilla Firefox, Internet Explorer , Safari, Netscape, etc.). But its size may be smaller than a music file
A web page may be very small or large depending on the amount of text and the number and quality of images integrated within the web page. For example, for the CNN.com home page is about 200KB (200 Kilobytes = 1,600,000 bits = 200,000 bytes). This is usually great for web pages. In comparison, Yahoo’s home page about 70KB.
Was how much bandwidth is enough?
Depending on the (surely you hate this answer: D). But this bener loh, because the bandwidth will determine the price of hosting that we plan, we must think about how much bandwidth we need. Most hosting measure the bandwidth that we use to count monthly, so we must think of our site the bandwidth required on a monthly basis.
If it does not intend to provide facilities to download files from your site, your bandwidth calculation formula is easy:
Average Daily Visitors x Average Page Views x Average Page Size x 31 x Fudge Factor
[(Average Daily Visitors x Average Page Views x Average Page Size x) +
(Average Daily File downloaded x Average File Size)] x 31 x Fudge Factor
Description of the formula above is:
Average Daily Visitors – The number of people expected to visit our site, this average daily. Depending selaris what sites we visited, it can be a number from 1 to 1 million.
Average Page Views, number of web pages that we hope to see visitors. If we have 50 web pages on the site, the average person can only see 5 pages each time they visit.
Average Page Size – The average size of our web pages, in Kilobytes (KB). If the site has been designed, we can calculate this easily.
Average Daily downloadable files – The number of downloads is expected to occur on our site. Calculate how many visitors and how many times a visitor downloads the file, on average each day.
Average File Size – Average file size of a file can be downloaded from our site. Similar to the size of web pages, if we already know which files can be downloaded, we can calculate this directly.
Fudge Factor – A number greater than 1. Use figure 1.5 to be safe as an unexpected value to estimate the missed 50%. But if I’m not sure (if it is a very important site benar2) then use the number 2 or 3 to ensure that the bandwidth that we have planned will not limit in one period (month).
Usually, hosting plans offer bandwidth in size Gigabyte (GB) per month. One month is 31 days at most, for it is the formula used in the daily average and multiplied by 31.
Most personal sites or small business sites will not need more than 1GB of bandwidth per month. If you have a website that consists of static web pages and the possibility of visitors who come to the site in a matter of days not too much, then take this small bandwidth. Sometimes if we use a bandwidth that exceeds the planning, hosting providers will provide overcharge and sometimes there is a bandwidth limit to testify.
So …. How much bandwidth do you need …?
