- 1TB、兆位元組（台灣多半直接講「一 T」「兩 T」，例如「這顆硬碟兩 T」）。注意台灣的「兆」在資訊裡指的是 10¹²，跟一般說的「兆」意思不同，所以說 TB 最不會誤會。
A terabyte is an amount of computer storage — the size of a hard disk, a memory card, a cloud account.
A terabyte一個terabyte(TB) is an amount of computer storage是一種電腦儲存空間的容量單位 — the size of a hard disk像是一顆硬碟、a memory card一張記憶卡、a cloud account或一個雲端帳戶的大小。
It sits one step above a gigabyte: 1,024 , or in the rounder way most people count, a thousand , which is a million . That is the honest at the heart of the word.
It sits one step above a gigabyte它比gigabyte大一級: 1,024 gigabytes是1,024個gigabyte, or在比較籠統的算法裡 in the rounder way most people count大多數人算成, a thousand gigabytes一千個gigabyte, which is a million megabytes也就是一百萬個megabyte。That is the honest muddle而這就是這個字 at the heart of the word內部老實說存在的一團混亂。
Computer engineers count in powers of two, so for them a terabyte is 1,024 ; disk makers count in plain thousands, so the 1 TB disk you buy shows up on your computer as about 931 GB, and every year people think their new disk is broken when it is not.
Computer engineers電腦工程師 count in powers of two是用二的次方在算, so for them所以對他們來說 a terabyte一個terabyte is 1,024 gigabytes是1,024個gigabyte; disk makers而硬碟製造商 count in plain thousands是用一般的千位在算, so the 1 TB disk you buy所以你買的1TB硬碟 shows up on your computer在你電腦上顯示 as about 931 GB大約是931GB, and every year每年 people think人們就會以為 their new disk is broken新硬碟壞了 when it is not其實並沒有。
Some careful writers use **tebibyte (TiB)** for the 1,024 version to keep the two apart, but almost nobody says that out loud. In real life a terabyte is roughly a of a million photos from your phone, or a few hundred hours of video — big enough that ordinary people only started needing the word in about the 2010s, and small enough that a phone will get there soon.
Some careful writers有些謹慎的作者 use 'tebibyte (TiB)'會用「tebibyte (TiB)」 for the 1,024 version來指1,024那個版本 to keep the two apart好把兩者分開, but almost nobody不過幾乎沒有人 says that out loud會這樣講出口。In real life在現實生活裡 a terabyte一個terabyte is roughly大約是 a quarter of a million photos二十五萬張照片 from your phone你手機裡的, or a few hundred hours of video或幾百小時的影片 — big enough大到足以讓 that ordinary people一般人 only started needing the word直到2010年代左右才開始需要這個字 in about the 2010s, and small enough而又小到 that a phone一支手機 will get there soon很快就會達到這個容量。
Written short as **TB**. Say it TERR-a-byte.
Written short as「TB」是它的簡寫 **TB**. Say it唸法是 TERR-a-byte。
core核心畫面
組成tera- + byte. tera- is the size prefix meaning a trillion (10¹²), from Greek teras, a monster or a marvel — the scientists who named the prefixes reached for a word meaning "monstrous" for something this big. byte is the small unit of computer information, eight bits, enough to hold one letter; it was made in the 1950s by respelling *bite* with a y, so it would not be mistaken for *bit* in writing.
