A. Both approaches are used when writing programs.

Explanation:

Procedural programming (PP), also known as inline programming takes a top-down approach. It is about writing a list of instructions to tell the computer what to do step by step. It relies on procedures or routines. Object-oriented programming (OOP) is about encapsulating data and behavior into objects.

Which is true of ASCII and Unicode?


Every character written in Unicode can be represented in ASCII.

Every character written in ASCII can be represented using Unicode.

ASCII requires more bytes than Unicode.

ASCII and Unicode both define accented characters.

Answers

Answer:

The correct options is;

Every character written in A S C I I can be represented using Unicode

Explanation:

All characters found in A S C I I can be found in Unicode such that A S C I I is a subset of Unicode whereby the meaning of the numbers from 0 to 127 are the same in both A S C I I and Unicode

The size of the A S C I I character in 8-bit A S C I I encoding is 8 bits while a Unicode U T F - 8 encoding has between 8 bits (1 byte) and 32 bits (4-bytes)

A S C I I assigns only 127 of the 255 possible numbers that can be stored in an 8-bits character, where the spare characters are then used by P C s for accented characters, therefore, it A S C I I does not define accented characters

Answers

Answer:

The answer is "Technician B"

Explanation:

The OBDII is a standardized, automated framework which the USA EPA had approved and installed into its whole year of modeling (MY) 1996 and then into modern light-duty vehicles and trucks, recognized as "on-board diagnostics II."  

The DTC framework is a set of problematic diagnostic codes that used alert you if a vehicle is unable to operate using an on-board Diagnostic System. If the system of the automobile identifies a problem, a special DTC code is generated as well as a position sensor is sent to the instrument cluster, that's why Technician B is correct.

Which decimal value (base 10) is equal to the binary number 1012?

Answers

Answer:

The decimal value of 101₂² base 2 = 25 base 10

Explanation:

The number 101₂² in decimal value is found as follows;

101₂ × 101₂ = 101₂ + 0₂ + 10100₂

We note that in 101 + 10100 the resultant 2 in the hundred position will have to be converted to a zero while carrying over 1 to the thousand position to give;

101₂ + 0₂ + 10100₂ = 11001₂

Therefore;

101₂² =  11001₂

We now convert the result of the square of the base 2 number, 101², which is 11001₂ to base 10 as follows;

Therefore converting 11001₂ to base 10 gives;

11001₂= 1 × 2⁴ + 1 × 2³ + 0 × 2² + 0 × 2 ¹ + 1 × 2⁰

Which gives;

16 + 8 + 0 + 0 + 1 = 25₁₀.

The decimal value in base 10 that is equal to the binary number 101_2 is; 5

We want to convert 101_2 from binary to decimal.

To do this we will follow the procedure as follows;

(1 × 2²) + (0 × 2¹) + (1 × 2^(0))

>> (1 × 4) + (0 × 2) + (1 × 1)

>> 4 + 0 + 1

>> 5

In conclusion, the decimal value we got for the binary number 101_2 is 5

You are trying to log in to your old computer, and can't remember the password. You sit for hours making random guesses... I'm sure you thought it was funny back when you came up with that password (chEEzburg3rz). Write a program that tells you whether your guess is correct. If it is correct, it should grant access like this: Enter password: chEEzburg3rz Access granted....
If your guess is incorrect it should deny access like this:
Enter password: lolcatZ
Access denied

Answers

Answer:

else:

     print("Access Denied")

Explanation:

The programming language was not stated; However, I answered your question using Python

The line initializes the password to chEEzburg3rz"

password = "chEEzburg3rz"

This line prompts user for input

userpassword = input("Enter Password: ")

This if condition checks if user input corresponds with the initialized password
