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.

Explanation:
The most significant bit is the sign bit (S), with 0 for positive numbers and 1 for negative numbers.
Normalize significand: 1.0 ? |significand| < 2.0
Always has a leading pre-binary-point 1 bit, so no need to represent it explicitly (hidden bit)
The following 9 bits represent exponent (E).(0 TO 511)
E is : actual exponent + Bias
Bias = 255;
The remaining 38 bits represents fraction (F).
Width of representation
smallest value :
Exponent: 000000001 because 000000000 is reserved
actual exponent = 1 – 255 = –254
Fraction: 000…00 \rightarrow significand = 1.0
