How do you usually read the hex literal "0x1F" aloud?
Read "0x1F" as "hex one-F" or letter-by-letter "oh-ex, one, eff". The "0x" prefix signals hexadecimal; speakers often just say "hex" then the digits. "1F" is "one eff" (F = the letter). You would NOT say "zero times" - the "x" is a prefix marker, not multiplication. For clarity on a call: "the value is hex one-F, that's thirty-one in decimal." Each hex digit A-F is read as its letter name: A, B, C, D, E, F.

How do you read the binary literal "0b1010" aloud?
Read "0b1010" as "binary one-zero-one-zero", digit by digit. The "0b" prefix means binary; say "binary" or "oh-bee" then read each bit individually: "one, zero, one, zero". Never read it as a decimal number like "one thousand ten" - in binary, "1010" equals 10 in decimal, but you pronounce the bits separately. For clarity: "binary one-oh-one-oh, which is ten in decimal." Reading bits individually avoids confusion about base when speaking aloud.

How do you read the IPv4 address "192.168.0.1" aloud?
Read "192.168.0.1" as "one-ninety-two DOT one-sixty-eight DOT zero DOT one." Each of the four octets is read as a normal number, and the dots are spoken as "dot" (or sometimes "point"). So 192 = "one ninety-two", 168 = "one sixty-eight". The separators are usually "dot" in networking speech, though "point" is heard. Never run the digits together. This is the classic home-router gateway address, so you'll say it often when configuring networks.

How is the hex digit "A" (as in 0xA3) read aloud?
Hex digit "A" is read as the letter "ay" (A). So "0xA3" is "hex ay-three". In hexadecimal, A=10, B=11, C=12, D=13, E=14, F=15, but you say the letter name, not the decimal value, when reading the literal. In noisy calls, some use the NATO alphabet ("alpha, bravo, charlie") to avoid mishearing, but standard reading is just the letter: "ay, bee, see, dee, ee, eff". So a colour like "0xFFA500" is "eff-eff, ay-five-oh-oh".

How would you naturally read the hex pair "FF" aloud?
"FF" is read "eff-eff", or casually "double eff". Each F is the letter name. In a MAC address or colour code, you read each hex digit by its letter: "FF:FF:FF" is "eff-eff colon eff-eff colon eff-eff", or "double-eff" repeated. You would not say "fifteen-fifteen" (the decimal values) when reading the literal. White in hex, "#FFFFFF", is read "eff-eff, eff-eff, eff-eff" or "all effs". The "double" shorthand (e.g. "double eff") is common and clear.
