Tutorials and wizards

I think that the tutorials are step by step instructions that can be found in different programs or games,  this tutorials are useful the individuals that do not understand the steps to follow or how to  engage something, like for example in a game, a tutorial can instruct an individual to use different controls or to know what to do. In the case of wizard this is a program or application that is downloaded that helps an individual to improve his uses of computer systems or other programs.


2)      In my opinion the tutorials and wizards are very useful for people that have no access to learn about computers and how to use them, or to use different programs and learn ,like for example Microsoft Office word or other software’s, in an easy way and effective with no use of a teacher or an extra individual. Wizards can also be useful to decrease technological damage like for example viruses that can damage the computer by generating step by step instructions of what to do when a virus attack or tries to enter a computer.

3)
·         Talk about different example of tutorials on software’s
·         Name 2 different Wizards
·         Explain how a Wizard works in at least 3 sentences
·         Can tutorials be seen in the day to day life?
·         Do wizards create dependence on individuals?

simulations


www.investopedia.com has a stock exchange simulator. It doesn't run a very complicated system as it takes all the data from the real stock market, using all the figures and values the market contains. This simulator can be used to start understanding and practicing in the stock exchange market as it treats with virtual money. Each user starts with $100.000 and can be invested in any way. It is very reliable as all the values are updated real time but the feel is not the same as the user is not earning or losing any real money.
Simulators can also be used for training methods, such as complex surgery where no mistake can me done so the doctor can see the reactions of the body. An other very common simulator is in the Formula 1 teams, where the drivers practice in a simulator to know better the track. It is much cheaper than practicing with the real car in the real circuit.
There may be some simulators that are not much real as the algorythms may not be very complex so the user will not find it useful but as time is passing by, simulators are getting much complex and the graphics are getting each time more real and at some point in the future they will be even better than real situations, so the users will find it very useful and reliable

slavehack in real life

SLAVEHACK LEARNINGS

Playing slavehack we learned different ways in which to hack computers remotely.  By doing this we could erase our logs to prevent getting hacked.  Most of this techniques exist nowadays but it isn’t so simple as it looks.
- DDOS attacks: 
Software: DosHTTP 2.0
- Bruteforce cracking:
Software:  Dsniff or Hyda
Social Engineering: This is technique implemented without any software.
 Erasing of logs and records:
Software:  Winzapper.
-Firewall Bypasser/Proxy Server:
Software (online): HideMyAss
All tools are methods are possible to use, however some are harder than others.
Cracking passwords is probably the most unlikely of all: this is really difficult and nearly impossible since this method consists on trying different password combinations to get a certain password.  Most web pages nowadays have a limit in tries.

The risks and threats of hacking are well-known and really risky. If you get caught you can pay from monetary penalties to jail penalties.  This is possible and has passes many times in hacking history.
