Email Explanation

Email (electronic mail) is a method of sending various types of file from one email address to another. It first sends the email to a central server, and when the receiver opens the inbox, the mail is then downloaded from the central server to their computer. An email can contain simple text, website links, image files, and many more. It can, also contain spam, which is an email with a fake address in the ‘From’ field of an email, leading the receiver to believe it’s from a trusted source There is also Viruses, Worms and Trojans, which can be attached to emails. A virus is a harmful piece of code that can replicate if the file location is opened. A Worm is a piece of code that can replicate itself in great volumes once installed, regardless if any files have been opened, and can ‘burrow’ into a system by itself, and allow their creator to take control of computer systems remotely. A Trojan is a piece of code made to look like an attractive attachment/download, and once installed it can do damage to a user’s system and take control of the user’s machine.
