Are there any differences between "update" and "upgrade"?

Solution 1:

If you're talking about software, there is, imo, even though the two do overlap. (A lot depends on the context: I'm assuming a general one below.)

Usually, when you update a software, you apply patches and additional bits and pieces that the seller provides you for free, in theory to keep your copy in line with the official version (which is likely more stable, more secure and may even provide you with some new / better options, functionalities.)

On the other hand, when you upgrade a software, you usually buy / pay extra for a version unavailable for free. Of course, an upgrade serves as an update as well (in most cases.)

An example: say you have an antivirus program that you did not pay for (it being made legally available for free), but which has a commercial version as well: You usually update its database (to keep you safe from newer threats) - but if you upgrade it, it means you pay for an advanced version that gives you extended protection: not just via an updated database but also through extended capabilities (like email-scanning, link-scanning etc that were unavailable in the free version, no matter how up to date your database was.)

(Again, a real lot depends on the context.)

Solution 2:

To update means to bring someone or something up to date, whereas to upgrade means to raise or improve something to a higher standard. The difference between these two is particularly apparent in the world of computers: an update is not always and improvement!

Solution 3:

To update means to make something more modern or up to date; it also means to give to somebody the latest (or up to date) information.
To upgrade means to take something to a higher standard/level; it also means to raise somebody to a higher grade or rank.

Looking in the Corpus of Contemporary American for phrases containing update or upgrade, I get the following data:

                    Instances
computer update     1
computer upgrade(s) 12
hardware update     2 
hardware upgrade(s) 11
software update(s)  30
software upgrade(s) 31

The sentences containing hardware update are both referring to a software tool.

The Hardware Update Wizard will search for an updated driver on your local drives as well as on Microsoft's Windows Update site, and it will install the driver if it finds one.

Select the option in the Hardware Update Wizard that lets you choose the location of the search and select the driver (the wording varies).
