File download ratio

The simplest way to transfer a file is through a data cable specifically made to transmit data. Nowadays, we can also transfer data wirelessly through radio frequencies like Bluetooth or Wi-Fi. We can now also upload or transfer data to the internet so that other people can access it.

The internet is a series of computer networks running all across the world. With the internet, we can now easily send any file to our loved ones, even if they are a thousand miles away from us, as long as they also have access to the internet. All we need to do is upload our file to the internet. Then, to access our file, people have to download it to their devices. Uploading and downloading data can take a while, depending on the file's size and transfer rate.

Think of it like pouring water into a beaker. Pouring water from one beaker to another will only take a little amount of time. However, if we place a funnel on one beaker, the amount of water flow will decrease due to the narrow part of the funnel. The flow rate of the water in this analogy is similar to the transfer rate of a file.

We can compare a funnel's narrow tube part to what is called the internet's bandwidth. The larger the bandwidth is, the more data that can be transmitted at a time. Therefore, a file can be transferred much faster if the internet connection has a larger bandwidth. Bandwidth is also, in a way, an internet connection's maximum capacity, and we can express it in units of bits per second. Internet bandwidth can also represent the maximum speed an internet connection can have.

However, when moving a file from one computer to another, the maximum transfer speed will depend on the slowest bandwidth that the data has to go through - which can be anywhere in the route.

To better understand this, let us consider an example. Let's say that your friend wants to send you his new MB megabytes video creation over his 10 Mbps megabits per second internet connection. On the other hand, you will be receiving the video file over your 5 Mbps home internet connection. For this example, let us assume that the upload and download speeds for both connections can use their entire bandwidths.

Since the file will also be coming through the much lower 5 Mbps connection, this will be the maximum transfer speed that we can get for this data transfer.

But, to determine the upload and download speeds of your connection, you can use any third-party speed test applications that can be accessed online through your browser.

Now that we know how to determine the transfer speed for our uploads and downloads, we can now calculate a file's download time or duration. Calculating download time is as simple as dividing the size of the file you wish to transfer by the transfer speed of the network that the transfer will go through.

However, we have to be careful with the units we use, since this could be quite confusing. Let us consider the example above for our sample computation. To calculate how long to download the MB video over a 5 Mbps internet download speed, we can use the equation below:. But first, let us convert the units of the file size in terms of megabits, which is equivalent to 1 million bits. To do so, we'll be using the conversion table above under the SI system. With that said, we now have this computation:.

As I said, there is no single function in excel to calculate the ratio for you. But, GCD function is close enough. It can help you to get common denomination for both of the values and then by using little concatenation, you can calculate the ratio. As I said, GCD can give you a common denominator for both of the values. So here you have to use GCD in both of the parts of the formula to get a common denominator. After that, you have to divide both of the values with that common denominator.

And, in the end, a little concatenation to join both of the values using a colon. PROs : 1. GCD function only works with integers and if you have decimals in your values, it will not work. This method works like a charm just like GCD function. First, you have to use text function to divide both of the numbers, and after that format the returning value in a fractional format.

PROs: 1. Simple to use and understand. Using round function to calculate a ratio is also a useful method. This is especially useful when you want to calculate ratio with decimals for accurate comparison.

So, in this situation instead of using them as they are you can divide them and show the final ratio with decimals. Do they create in photoshop from the ratio, the biggest size they want to offer like : 24x36''? Instead advertise it as for example print size Inch: 4x6, 8x12, 12x18, 16x24, 20x30, 24x You are correct to assume to save at the biggest size in that ratio and then if they want to print smaller that's no problem.
