Calculating Download Time – Bits, bytes, bandwidth & Speed Explained

The computer science earth is full of jargoon. We ’ ve adopted some of it into our casual lives : “ on-line ”, “ Google ”, and of course, “ Broadband. ” We know that broadband is a fast connection, particularly compared to the slow-old days of dial-up internet. The accelerate a Dial-up internet connection topped out at is “ 56k ”. This was a theoretical rush, and many technical factors had to match up to achieve it. That meant a download rate of about 7KB/s ( keep read to know how we worked that out ). The differences between “ Kb/s ” and “ KB/s ” make it confusing at times. So what is the difference, and how does it affect your internet connection and your download speed ?

Bits vs bytes

Computers are digital systems and “ address ” in binary. That means 1s and 0s – information. One of these numbers is a called a spot, the smallest unit of information. When we have 8 of these bits, we call it 1 byte. 1000 byte is called a Kilobyte ( KB ) and 1000 of those are called a Megabyte ( MB. )
The major remainder between bits and bytes is that bits are normally used to measure travel rapidly, while bytes are used to measure size. Think of bits per second as a accelerate in kilometers per hour. On the other hand, bytes are like litres, filling up a hard drive or storage device .

Making sense of it all

The speed of your internet connection is normally expressed as Kilobits or Megabits per second ( Kb/s or Mb/s – note the humble ‘ barn ’ standing for bite. ) You may have seen this in the past, with ADSL2+ offing theoretical maximal speeds of up to 24000kbps ( Kilobits per second ).

To determines how firm your internet connection can download data per irregular, you must convert the speed Mb/s ( Megabits per second ) or Kb/s ( Kilobits per second ) into Megabytes ( MB ) .
Let ’ s say your internet connection speed is 5Mb/s ( Megabits per second ). This means you can download at 625 Kilobytes per second ( KB/s ), or 0.625 Megabytes per second ( MB/s ). Remember, 8 bits equal 1 byte, so to work it out you need to divide it by 8. so our equation is : 5 Megabits per second / 8 = 0.625 Megabytes per second .
so to download a 10 Megabyte ( MB ) file on a 5Mb/s connection, it will take you 16 seconds to download. ( 10 Megabytes / 0.625 Megabytes per second base = 16 seconds to download the charge ). All you need to remember is this simpleton formula :

  • File Size In Megabytes / (Download Speed In Megabits / 8) = Time In Seconds
  • A 15 Megabyte file, downloading at 10 Megabits per second: 15 / (10/8) = 12 seconds

Common speed requirements

Your connection can affect the way your business operates, particularly if you are downloading or streaming files in the GB or TB ( 1,000,000,000,000 bytes ! ) compass .
If you have a little business with lone a few employees and only use the internet to browse the web, send emails and make the episodic Skype address, a 10-12Mbps connection may be sufficient .
For streaming HD video, teleconference, and using defile services ( Dropbox for model ), a business needs at least 25Mbps .
When the number of devices increase, your bandwidth must keep pace. If you have 10 employees HD streaming simultaneously, you have to allocate enough bandwidth to each drug user. That means increasing the bandwidth to somewhere around 60-100Mbps.

Not all connections are equal

equitable because your connection has a maximal of, say, 24Mbps ( such as ADSL2+ ), does not mean your especial device will download at that travel rapidly. Factors such as distance from the exchange, inner cable, network devices and its configuration, the locate you are accessing, early users on your network, or even high numbers of users in your area ( which is known as controversy ) competing for bandwidth can all diminish the download speed you receive .
If you are in doubt of what you need, Broadband Solutions can tailor a broadband connection that meets your commercial enterprise requirements. We determine what is the best available connection that you can receive, whether being Midband Ethernet, Fibre Optic, Microwave, ADSL2+ or NBN .
