When you use 3 bits to encode a set of symbols, you can represent a maximum of 2^3 = 8 different symbols.

What is Binary code?

Binary code is a system of representation using only two digits: 0 and 1. It is used as a method of digital data transmission, storage and computation. In binary code, each digit represents either a logical “on” or “off” state, or a binary number.A binary code is used in computer systems to store and transmit data.

For example, each letter, number, or symbol on a keyboard is represented as a unique binary code. The computer's processor uses binary code to process information, make decisions and execute commands.

The maximum number of different symbols that can be encoded with 3 bits is 8.

Each bit can be either 0 or 1, so there are two possibilities for each bit. With three bits, there are 2 * 2 * 2 = 8 possible combinations. These combinations can be used to represent 8 different symbols.

For example, the binary codes for the 8 symbols can be:

000 = symbol 1

001 = symbol 2

010 = symbol 3

011 = symbol 4

100 = symbol 5

101 = symbol 6

110 = symbol 7

111 = symbol 8

Therefore, using 3 bits to encode symbols, we can encode a maximum of 8 different symbols.

C) Buffer overflow. A typical cyberattack known as a "buffer overflow attack" takes advantage of a vulnerability known as a "buffer overflow" where user-controlled data is written to memory.

The attacker can overwrite data in other areas of memory by sending more data than can fit in the allotted memory block. Attackers may conduct buffer overflow assaults for a number of reasons, including overwriting crucial code or data to cause the program to crash, inserting malicious code to be executed by the program, or changing crucial values to alter the program's execution flow.

When the amount of data exceeds the memory buffer's storage capacity, a buffer overflow (or buffer overrun) occurs. The application that is trying to copy the data to the buffer as a result overwrites nearby memory locations.

The most well-known buffer overflow exploits are listed below: The most frequent form of buffer overflow attack, called stack overflow, involves a buffer overflow in the call stack. Attacks that target data in the heap, an open memory pool, are called heap overflow attacks.

Out of 5,040 possible passcode of length 4, the probability that the passcode generated begins with a 3 is 10%.

Assuming that the alphabet contains 10 digits from 0 to 9, and the passcode cannot contain repeated digits, there are 10 choices for the first digit, 9 choices for the second digit (since one digit has already been used), 8 choices for the third digit, and 7 choices for the fourth digit. Therefore, there are 10 x 9 x 8 x 7 = 5,040 possible passcodes of length 4.

Out of these passcodes, there are 9 x 8 x 7 = 504 passcodes that begin with the digit 3, since once the first digit is fixed to be 3, there are 9 choices left for the second digit, 8 choices left for the third digit, and 7 choices left for the fourth digit.

So the probability of the passcode generated beginning with a 3 is:

P(First digit is 3) = Number of passcodes that begin with 3 / Total number of possible passcodes

P(First digit is 3) = 504 / 5,040

P(First digit is 3) = 0.1 or 10%

Therefore, the probability that the passcode generated begins with a 3 is 10%.

In this case, no exception will occur when the value of an unsigned short variable is decremented from zero.

What is C programming?

C is a high-level, general-purpose programming language that was developed in the early 1970s by Dennis Ritchie at Bell Labs. It was designed to be a low-level language for systems programming and to provide a portable, efficient, and flexible way of writing software for a wide range of computer systems.

In this case, no exception will occur when the value of an unsigned short variable is decremented from zero.

Unsigned short variables are used to store non-negative integer values, with a range of 0 to 65535 (2^16 - 1). When the value of an unsigned short variable is decremented from zero, it will wrap around to the maximum representable value (65535) instead of becoming a negative number.

This behavior is defined by the rules of unsigned arithmetic in C and C++, where unsigned variables are treated as having a "modulo" range that wraps around when the minimum or maximum value is exceeded.

In other words, decrementing an unsigned short variable from zero will not result in an exception or error, but the value stored in the variable will change to the maximum representable value (65535).
