Answer: True ✔
💡 Trusted organizations don't need your password, and any message asking for it is a clear sign of a scam.
Q80: It is safe to use your date of birth as a password.
Answer: False ✖
💡 Your date of birth is easy to guess and known by many people, so it is one of the weakest kinds of passwords.
Q81: Two-step verification makes an account harder to hack even if someone knows the password.
Answer: True ✔
💡 The second step needs something you own, like your phone, so the password alone is not enough to log in.
Q82: What is the benefit of backing up your important files?
Answer: Keeping a copy you can restore if the original files are lost or damaged
💡 Save a copy of your files somewhere else, such as an external drive or a cloud service, so you don't lose them if the device breaks or gets malware.
Q83: What do we call the commands a programmer writes in a programming language?
Answer: Code (source code)
💡 Code is text written following the rules of a programming language, and it is later turned into instructions the computer carries out.

Answer: Someone may have found out your password, so don't give the code to anyone and change your password
💡 The code is usually sent when someone tries to log in to your account or recover it, so its sudden arrival is a warning that someone is trying to get in; don't give the code to anyone, and change your password.
Q88: What is the name of the language made of zeros and ones that the processor understands directly?
Answer: Machine language
💡 The processor understands only binary machine language, which is why programs written in programming languages are translated into it before they run.
Q89: How many different values can be represented with one byte (8 bits)?
Answer: 256
💡 Each bit has two possibilities, so eight bits give 2 multiplied by itself 8 times = 256 values, from 0 to 255.

Q92: A loop repeats the two commands "move forward 100 steps, then turn 90 degrees" four times. What shape is drawn?
Answer: A square
💡 Four equal sides with four right angles make a square, and the loop saves us from writing the two commands four times.
Q93: In a program that starts with "x = 5" and then runs "x = x + 3," what does the value of x become?
Answer: 8
💡 The variable takes its old value of 5 and adds 3 to it, then stores the result, 8, in place of the old value.
Q94: In the command "If it is raining, take the umbrella," what happens if it is not raining?
Answer: The take-the-umbrella command is not carried out
💡 A condition carries out the command only when it is true; if it is false, the program skips to what comes after it.
Q95: Why is it advised to install system and program updates promptly?
Answer: Because they close security holes that hackers could exploit
💡 Many updates fix newly discovered security holes, and putting them off leaves the device open to attacks.

Answer: Using a trusted password manager program
💡 A password manager stores them encrypted behind one strong master password, so you don't need to memorize them all.
Q101: What is a computer virus?
Answer: A malicious program that copies itself and spreads to damage or steal data
💡 It is called a virus because it spreads from one device to another like an infection, often through untrusted files or links.
Q102: Which program detects and removes malicious software on the device?
Answer: An antivirus program
💡 An antivirus program scans files, compares them to known malware patterns, and watches for suspicious behavior.
Q103: Why is it advised to use a different password for each account?
Answer: So that not all your accounts are hacked if one password leaks
💡 Hackers try a password leaked from one site on other sites, so different passwords limit the damage to one account.
Q104: What happens in an "infinite loop" in a program?
Answer: The commands repeat endlessly because the exit condition is never met
💡 If nothing changes to make the condition true, the program keeps going around the same loop, which is a common beginner's mistake.

💡 A bit is a single digit whose value is 0 or 1, and larger units are made by grouping bits.
Q110: How many bits are in one byte?
Answer: 8
💡 A byte is made of 8 bits, which is enough to represent one English letter in simple encodings.
Q111: Why does the computer use the binary system (0 and 1)?
Answer: Because its electronic circuits work with two states: on and off
💡 The transistors inside the computer either let current flow (1) or not (0), and all data is built from these two digits.
Q112: What do we call the process of finding and fixing errors in a program?
Answer: Debugging
💡 The programmer tests his program and traces its steps until he finds the cause of the problem and fixes it, which is a basic programming skill.
Q113: What is an algorithm?
Answer: A set of clear, ordered steps for solving a problem
💡 A cooking recipe is an example of an algorithm: steps in a set order that lead you to the result, and programs are algorithms written in a computer language.
Q114: If you are cyberbullied, what is the best thing to do?
Answer: Don't reply, save the evidence, tell someone you trust, and report it
💡 Replying with insults makes the problem worse, while saving the evidence, blocking, reporting, and asking for help stop it.
Q115: What is cyberbullying?
Answer: Hurting, insulting, or threatening someone online
💡 Cyberbullying happens through hurtful messages, posting pictures without permission, or repeated mockery, and it hurts as much as face-to-face bullying.
Q116: Which information should not be posted publicly on the internet?
Answer: Your home address
💡 Your address is private information that strangers could misuse, so keep it for people you trust in real life.
Q117: You got a message saying: "You won a prize! Enter your password to claim it." What is the right thing to do?
Answer: Ignore the link and delete or report the message
💡 Real prizes never ask for your password, and this trick is one of the most common phishing tactics.
Q118: What is phishing?
Answer: Fake messages or websites that pretend to be a trusted organization to steal your data
💡 The scammer throws out "bait," such as a message in the name of a bank or store, so you will type your password or personal data into it.
Q119: What is meant by two-step verification?
Answer: Requiring extra proof, such as a code sent to your phone, after the password
💡 Even if someone knows your password, they cannot get into your account without the second step, which only you have.

💡 Shortcuts save time: C for Copy and P for Print, Z undoes the last mistake, and V pastes what you copied.
Q124: Arrange what happens when you open a website by typing its address:
Answer: You type the website address in the address bar then You press Enter then The browser requests the page over the internet then The page appears on the screen
💡 The browser fetches the page only after the address is typed and confirmed; then it requests it from the server and displays it when it arrives.
