Answer: The goals of computer security are to protect computers and users from data theft or loss as well as damage to any part of the computer.
Explanation: Common means of achieving computer security are firewalls, anti-virus software and this can fail due to hardware problems or
weaknesses that prevent malicious attacks.
To answer this question, think of a time when you experienced any one of these. For example, personally, I was once an unfortunate victim of a general malicious attack that took advantage of a weakness in my anti-virus software. After clicking on a link on a dodgy website, a virus was installed on my computer. My computer finally crashed, without any hope of restarting it. I lost all my data and I had to buy a new computer. This was a malicious attack.
However, sometimes people can be specifically targeted to steal their data or monitor their activities.
A Mouse and a Keyboard are examples of eternal input devices. The monitor, printer, speaker and Fash drive are all external output devices. Seven basic internal components in a computer tower are the power supply unit, central processing unit, hard disk drive, RAM modules, motherboard, video card and a sound card.
Answer:
The answer is "Option A".
Explanation:
The elliptical curve cryptography system needs much shorter keys for cryptography, and it is very powerful because of the RSA cryptography method. It is also known as a key of 1024-bit, which is in comparison is equal to the 160-bit ECC key for cryptographic, that's why other options are not correct, which is defined as follows:
- In option B, It is higher the ECC key system, that's why it's wrong.
- In option C, It is a part of the RSA system but its value doesn't match the ECC system, that's why it is wrong.
- In option D, It's valued is just double to the RSA system, that's why it is wrong.
