Explanation :
UTF-8 is an 8-bit variable-length encoding scheme designed to be compatible with ASCII encoding. The encoding scheme distributes a Unicode code value's bit pattern across 1, 2, 3, or even 4 bytes. This encoding is a multi-byte encoding scheme. Unicode provides a unique number for every character. It including punctuation marks, mathematical symbols, technical symbols, arrows, and characters making up non-Latin alphabets such as Thai, Chinese, or Arabic script. Unicode is an industry standard for the consistent encoding of written text. Unicode defines different character encodings, the most used ones being UTF-8, UTF-16, and UTF-32. UTF-8 is definitely the most popular encoding in the Unicode family, especially on the Web. Additional Information ASCII (American Standard Code for Information Interchange) character set contains 128 characters for English letters, numbers, and some control characters. ASCII encoding maps each character to 1 byte with the leading bit set to 0, and the other 7 bits representing the code point of the character.

Explanation :
- Gigahertz is a measurement of something happening X times per second. - 4 gigahertz means that the thing is happening 4 billion times a second. When we say that the processor runs at 4ghz we mean that the “main clock” of the processor is ticking 4 billion times per second. - CPUs are digital circuits. They only do an action when the clock drives the circuit to do the action. Think of that as the RPM of a car. The faster the clock goes, the faster the actions happen. - For performance, clock speed is important but it's not directly comparable between different CPU architectures. Clock speeds are comparable only in the same family of cpus that share an architecture.
