7 HACKING So what is hacking?

8 HACKING hacking is very bad. You may not know but using someone else's password on a computer is hacking. Hacking is unauthorised use of computer and network resources this means somebody is entering without permission or the person allowing them to enter. Hackers can get through by emails, or looking in on peoples passwords by spying. You may not realise but you could be a hacker if you look at others files on the computer without them letting you if you don’t want someone to guess your password choose a complicated one with numbers, capitals, lower case. Don’t choose a name of a sibling, pet or a birthday because these are most commonly guessed.

9 Stop hackers Hackers like computers that are connected to the internet, they are easier to access. So close the internet when you have finished. Use firewalls!

10 What to do if you suspect a hacker Tell an adult and they can sort it out. It can be easy for your computer to be accessed, so get a firewall. Some of your files may unfortunately be changed. Don’t worry!

11 What do they do???? So, hackers, as popularly defined, are computer experts who spend enormous amounts of time trying to hack into the security of networks, Web servers and email servers. Usually they use a selection of specialist software to identify weaknesses. Most do it for fun and as a challenge. They're not interested in attacking private individuals. It's the big companies and authorities they go for. There are only a few aspects of hacking that you have to worry about as a private individual. One is that your details are on various company databases, and when these are cracked, information about you can be stolen. Turn your computer off at night! Most websites will tell you if your password is strong-this can be helpful.

12 Backups!

13 What are backups? What is Computer Backup? Computer backup is the storing copies of your files. The reason that we make computer backups is to protect against the event that something happens to damage our files so they are no longer usable. If we have backups of our files, then we can restore these files to our computer through our backups. What is Involved in Computer Backup? Computer backups can be made in very different formats. The traditional method of backing up computer files was the floppy disk. However, floppy disks are becoming increasingly obsolete. It is already not uncommon to not even see a new computer that includes a floppy disk drive when you go to the computer store, and it is becoming almost impossible to actually get a new computer that includes such a drive. Floppy disks can only hold 1.4 megabytes of data, and there are formats which can hold much more.
