They are files on your computer that contain bits of information. A lot of companies use them to hold your username for the site for example so garden&gossip could have 'spec' in a file on your PC.
Other uses are to record the sort of things you like looking at so if you shop on line, they might know you order oats a lot so suggest that next time you are ordering. These uses are ok.
A lot of sites make money from advertising so like to store more info about you. so if you look at greenhouses, then you visit other sites, you will see adverts for greenhouses. They are not usually malicious but can tend that way with some of the things some companies use them for, particularly some types of 'market research'. A lot of firms can make money (which is what it is ll about) by tracking what you are up to on the web. Probably the google search engine together with gmail is one application that collects a lot of data about you.
You can delete all the cookies from a browser which I do occasionally but it does mean you need to remember all the logins for sites you visit as everything disappears.
All browsers have different facilities. I use firefox and for example, that has an option to delete all cookies and site data when firefox closes. You can enter sites as exceptions to this. So you could put in your bank and garden&gossip as you trust these sites.
