Bandwidth is the amount of data that can be transmitted in a given amount of time. The Bandwidth differs when it comes to digital devices and analogue, so for example for digital devices the bandwidth is usually in bits per second, whereas analogue is usually cycles per second or Hertz. that. If you use a low bandwidth connection, then it can seem a very slow wait for pages to load, so for example if you had a 10 Mbps connection you could around send 4.5 GB of data in an hour, whereas having a 20 Mbps you could send around 9GB in an hour or under.
Number of hits
A hit is basically the retrieval of an item such as a page or image from a web server, so for example if a user requests a page that has 6 images on it, then that would be classed as 7 hits. This is because it is classed as one hit for the page and then however many for images/graphics etc, but the more you request at once from the web server the more likley it is to take longer so say if a user wanted to requests a page that has lets say 20 images, this is more likley to take longer to load, rather then a page that may have 6 for example.
There are many different file types, which can range from bitmap, vector,jpg, gif etc and file type is what a file contains so this may be in the form of a document images etc. To identify a file the computer will use something called a file extension which will identify the paticular type of file. So for example a jpeg” file, is more compressed and of a lower quality compared to a wav file, therefore it would take a shorter time to load, so the more compressed and low quality a file is the less time it will take to load in comparison to a file which is of high quality.
