In computing, a hacker is any skilled computer expert who uses their technical knowledge to overcome a problem or otherwise gains remote access to a protected computer system mainly to get thrill out of it.
A cracker is also a skilled computer expert but he/she breaks into or otherwise violates the system integrity of remote machines with malicious intent. Having gained unauthorized access, crackers *** vital data, deny legitimate users service, or cause problems for their targets.
Few netiquettes are as follows:
- Respect other‟* privacy
- Acknowledge and return messages promptly.
- No spamming
- When typing never write in all capital letters. That is considered shouting.
