How is "KB" (kilobyte) said aloud?
KB can be said either as "kilobyte" /ˈkɪləbaɪt/ (expanding the abbreviation) or "kay-bee" (using the letter names K and B). Both are common and understood. So "the file is 512 kilobytes" or "512 K-B." In practice, "kilobyte" is more common when stating sizes ("a 2-kilobyte header"), while "K-B" appears in written contexts. The prefix "kilo" is always "KIL-oh" /ˈkɪloʊ/ with a short "i." Be careful: "KB" means kilobytes (8 bits each), while "Kb" or "kbit" means kilobits — an important distinction in networking.

How is "GB" (gigabyte) most commonly read in conversation?
GB is most commonly read as "gigabyte" /ˈɡɪɡəbaɪt/ or, informally, just "gig" /ɡɪɡ/. So "16 gigabytes of RAM" or "16 gigs of RAM." "G-B" (spelling the letters) is less common in conversation. The informal "gig" is extremely widespread: "I only have 2 gigs free on the drive." For speeds, "gigabit" /ˈɡɪɡəbɪt/ is different from "gigabyte" — networking uses gigabits per second (Gbps), while storage uses gigabytes (GB). In conversation: "gig" typically means gigabyte in storage contexts.

What is the difference between "bit" and "byte" in spoken pronunciation?
Bit /bɪt/ uses the short /ɪ/ vowel (same as "sit" and "fit"), while byte /baɪt/ uses the diphthong /aɪ/ (same as "bite" and "kite"). They sound completely different. "Bit" rhymes with "kit," "byte" rhymes with "kite." This distinction matters enormously: "100 megabits per second" (network speed) vs "100 megabytes" (storage). In speech, always enunciate the vowel clearly: "bit" (short) vs "byte" (long diphthong). Confusing them in a client call about bandwidth could create significant misunderstandings.

How is "TB" (terabyte) said aloud?
TB is said as either "terabyte" /ˈtɛrəbaɪt/ (expanding the abbreviation) or "T-B" in written/technical contexts. In casual speech, "tera" /ˈtɛrə/ is the prefix (from Greek for "monster" or "12th power"). So "a 2-terabyte hard drive" or "2 T-B." "Tee-bee" as two letters is also used but less naturally than saying "terabyte." The progression KB → MB → GB → TB is: kilobyte, megabyte, gigabyte, terabyte. Beyond that: PB (petabyte, "PET-uh-byte") and EB (exabyte, "EX-uh-byte").

How is "PB" (petabyte) typically spoken, and when would you encounter it?
PB is said as "petabyte" /ˈpɛtəbaɪt/ (expanding it) or "P-B" as letters. "Peta" is the SI prefix for 10^15. So "we store 2 petabytes of user data" or "2 P-B." In everyday engineering, petabytes appear in discussions of large-scale data platforms, data lakes, and object storage. "Pee-bee" as two letters is used but "petabyte" is the clearest spoken form. The full scale: kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB), petabyte (PB), exabyte (EB). In conversation, "petabyte" is pronounced "PET-uh-byte" — stress on "PET."
