What
is the difference between Upload and Download?
Uploading means that sending files
from our local system to another remote location such as a server, over the
network. For an example, if we want to build a website, we should upload the
required files, images and other content to the relevant server where we host
the website. When considering the Internet, every time we send a request for a
web page using a browser, the data containing our IP address and the web page
we have requested, is uploaded to the server where the requested page is
available.
The time needed to upload depends on the size
of the file we send. Small text based files can be sent quicker than the larger
music files, heavy video files, images or other large multimedia files. Most probably,
uploading can be performed while doing other tasks on the computers. After
uploading files to a server, it will be available for the other users, too.
Download
Downloading is transferring data or
information from a server to our client computer. For example, the same files
which have been uploaded to the server can be downloaded by another user to the
hard disk of a local system. When considering the Internet, in order to view
the content of a requested web page on a browser of the user’s PC, the web page
content including the images are downloaded first from the particular server.
The time cost for downloading a file depends
on the size of the file. When the file gets larger, the time takes to download
the file also increases. As these files are downloaded to a personal computer,
only the user of the machine can access those files.
