  • Case sensitivity — Used to describe how a computer program, e.g. a Browser, interprets upper and lower case letters, e.g. in the name of a program, the name of a folder stored on your computer, or the name of a website. Some computer programs may be case sensitive, in other words they make a distinction between capital letters and lower case letters so that, for instance, Manchester is perceived as different from manchester. Other programs may not make a distinction and perceive capital letters and lower case letters as one and the same. Be especially careful when typing the names of websites, as case sensitivity may be crucial and you may not be able to find the website if you fail to type capital letters in the right places.
