How the hacking is possible if https is apply?
Most hacks happen through insecure software. HTTPS is about preventing web traffic from being read. It does only little help to prevent websites from getting hacked

@M-Rocky said in CS101 Lecture 1 Discussion:
sir what is the difference between Information Technology and Computer Science???
Information Technology and computer science degree can both prepare you for jobs in the tech field, they often appeal to different types of people based on the slightly varied skill sets. Computer science involves more independent work creating computer programs and applications, using algorithms and writing code. On the other hand, IT professionals focus more on using technology to support business goals while frequently interacting with others to help solve tech issues either over the phone, in person or via email.

Sir
byte ans character formula to remember
e.g space=32
Dear Student,
Yes, ASCII code of character space is 32. You can see the 256 characters ASCII table for all values.
How to use the ASCII code:
Without knowing it you use it all the time, every time you use a computer system, but if all you need is to get some of the characters not included in your keyboard should do the following, for example:How typing: Spanish letter enye, uppercase N with tilde, EÑE, enie ?
WINDOWS: on computers with Windows operating system like Windows 8, Win 7, Vista, Windows XP, etc…To get the letter, character, sign or symbol “Ñ” : ( Spanish letter enye, uppercase N with tilde, EÑE, enie ) on computers with Windows operating system:
- Press the “Alt” key on your keyboard, and do not let go.
- While keep press “Alt”, on your keyboard type the number “165”, which is the number of the letter or symbol “Ñ” in ASCII table.
- Then stop pressing the “Alt” key, and …you got it! (137)

AoA sir Hope you are Fine kindly sir tell me about what is freelancing ?
Freelancing is a self-employed person who offers services, often working on several jobs for various clients at one time. Freelancers usually make money on a per-task basis, charging hourly or daily rates for their work. Freelance work is usually for a short-term.

Abacus was a tool for calculation used in the ancient times. It is considered the basis for the first computer that was invented. For details about its history and how it worked, I would strongly recommend you to watch the topic videos about this concept and also visit the following link for detailed history.

Sir, what are the steps, in sequence, involved in processing the data into an output?
Processing depends upon the input provided by the user and the expected outcome. For example, if we want to add 2 numbers than the sum operation will be performed by using following steps:
• Convert the decimal numbers into binary numbers
• Perform SUM operation
• Convert the binary numbers back to decimal numbers
• Then send desired outcome to any output device -
