What are the differences between the Internet and the World Wide Web?
Internet: The global network infrastructure. | World Wide Web: A service that uses the Internet to access linked hypertext documents.
What are the differences between ASCII and Unicode?
ASCII: Represents characters using 7 or 8 bits. | Unicode: Represents characters using a variable number of bits (up to 4 bytes), supporting a wider range of characters.
What are the differences between positive and negative impacts of the Internet?
Positive: Increased access to information, global communication. | Negative: Privacy concerns, cybersecurity risks.
What are the differences between random.random() and random.randint() in Python?
random.random(): Returns a random float between 0.0 and 1.0. | random.randint(a, b): Returns a random integer between a and b (inclusive).
What are the differences between sequence and selection control structures?
Sequence: Instructions are executed in order. | Selection: Code blocks are executed based on a condition.
What are the differences between lossy and lossless data compression?
Lossy: Some data is lost during compression, reducing file size significantly. | Lossless: All data is preserved during compression, allowing for perfect reconstruction.
What are the differences between a client and a server?
Client: Requests services from a server. | Server: Provides services to clients.
What are the differences between a variable and a constant?
Variable: Its value can change during program execution. | Constant: Its value remains the same throughout program execution.
What are the differences between a compiler and an interpreter?
Compiler: Translates the entire source code into machine code before execution. | Interpreter: Translates and executes the source code line by line.
What are the differences between a firewall and antivirus software?
Firewall: Prevents unauthorized access to a network or computer. | Antivirus: Detects and removes malicious software from a computer.
What is a variable?
A named container that stores information which can change during program execution.
