| How is 2ⁿ, where n is bits, equivalent to bytes? Posted: 20 Feb 2022 03:59 PM PST Not considering signedness, n bits can represent 2ⁿ different values. For example, 8 bits can represent 2⁸ = 256 different values, and so on On the subject of processors, 2ⁿ determines theoretical memory addressing limits. For example, without PAE a 32-bit processor could address a maximum of 2³² ≈ 4 GB of RAM. But, as per the first paragraph, 2³² would also give the total number of different memory addresses—so how is this equivalent to bytes? To try and support the crux of my question, let's return to my initial point of 8 bits. If 2³² ≈ 4 GB, then it must also be true that 2⁸ = 256 B. However, if 8 bits = 1 byte, then it implies that a byte is equivalent to 256 bytes. Surely not? So, how is 2ⁿ equivalent to bytes as well as the number of memory addresses? I must disclose that I'm not a computer scientist etc, so apologies if this seems like a daft question! [link] [comments] |
| What are the hottest techincal topics to write a book about to get published? Posted: 20 Feb 2022 12:59 PM PST Im thinking to write a technical book. I have deep practical knowledge in AI, Machine Learning, and Blockchain. My suggestons are:
