Answer: Computer's BIOS
Explanation:
Following the information given in the question, the highest level of security that is offered by LoJack can be achieved when Persistence Module resides in the computer's BIOS.
The BIOS (basic input/output system) refers to the program which the microprocessor of a computer uses in starting the computer system when the computer is powered on. It should also be noted that the BIOS is used in managing the data flow that exist between the operating system of the computer and the attached devices like the keyboard, hard disk, mouse, etc.

In UNIX the file system the file system is a central part of the operating system. The file system is for storage and retrieval of information. Programs that form the UNIX system also stores information in files.
UNIX file systems supports three files namely: ordinary file, directory files, device files or special files.
If we need to access bytes 2500-2503 it means the bytes are within the third block. So we will need only one access.
Note this is because the file control block (inside) is within the memory. If file control block was not in the memory we would have needed more disk accessses.
A syntax error is an error in the syntax of a sequence of characters or tokens that is intended to be written in a particular programming language. For compiled languages, syntax errors are detected at compile-time. A program will not compile until all syntax errors are corrected.
Answer:
a) 228
b) 940
c) 255
Explanation:
To convert a hexadecimal number to decimal, multiply each hex digit by 16^(position-1) and add the components.
For example, 0x 34 = 3* 16^(2-1) + 4*16^(1-1) = 48 + 4 = 52
Evaluating the given numbers:
a) 0xE4 =>
E corresponds to 14. So the decimal representation is 14*16 + 4 = 228
b) 0x3AC =>
A corresponds to 10 and C to 12. So the decimal representation is 3*16^2 + 10*16 + 12 = 940
c) 0xFF =>
F corresponds to 15. So the decimal representation is 15*16 + 15 = 255
