A bit, short for bi nary digit, is the smallest unit of measurement used for information storage in computers. The difference between a bit and a byte is size, or the amount of information stored.

By rearranging the bits within the octet, a byte is capable of producing 256 unique combinations to form letters, numbers, special characters and symbols. This also helps people to remember the difference between greater units, such as the kilo bit and kilobyte.

A kilo bit is 1,000 bits, though in the binary system, it is designated as 1024 bits due to the amount of space required to store a kilo bit using common operating systems and storage schemes. For simplicity, however, most people think of kilo as referring to 1,000 to more easily remember what a kilo bit is.

Knowing the difference between a bit and a byte helps to explain megabits, megabytes, gigabits and gigabytes. Internet connection speeds are expressed in terms of data transfer rates in both directions (uploading and downloading), as bits or bytes per second.

Abbreviations are, unfortunately, not standardized, making it easy for customers or potential clients to confuse a bit and a byte when trying to determine how fast something is. Read on to learn the difference and figure out what broadband speed you need.

Connection speeds and data sizes are measured differently, but people tend refer to them both as 'megs'. The problem is that the word 'meg' actually refers to two very different values: megabits and megabytes.

By extension, there are eight megabits in every megabyte, and one gigabyte is eight times bigger than one gigabit. Based on the file size and your connection speed, you can estimate how long it'll take you to download something.

Before you start reaching for your calculator, read our guide to download times. We've pulled together a list of the most common broadband speeds and file sizes to give you an idea of how long it will take to download films, TV series, songs and more.

It's easy to figure out based on common sense: an uppercase 'B' is physically larger than a lowercase 'b', and a byte is larger than a bit. While there are many file sizes, most of us only need to know a little (no pun intended) of prefixes.

There are eight bits in a byte, so to translate from one to the other, you can multiply or divide by eight. In this section, we'll learn how bits and bytes encode information.

The bit stores just a 0 or 1: it's the smallest building block of storage. ASCII is an encoding representing each typed character by a number Each number is stored in one byte (so the number is in 0.255) A is 65 B is 66 an is 96 space is 32 “Unicode” is an encoding for mandarin, Greek, Arabic, etc.

Each letter is stored in a byte, as below 100 typed letters takes up 100 bytes When you send, say, a text message, the numbers are sent Text is quite compact, using few bytes, compared to image etc. One byte works well for individual characters, but computers are also good at manipulating numbers.

Assuming that KB stands for kilobyte, then the next smallest abbreviation would be B for bytes. There is no smaller amount of data then one bit.

It is obvious that 1 TB(Term Byte) = 1024 GB (Gig Byte) so 1 TB is larger and has double more space than 500 GB. Some of you local, typically family owned furniture companies may be will to cut package deals for their customers.

Especially since they have to compete with the larger company stores or even a Walmart; in which I doubt any of them would have deals like that (or make one really). Historically, a byte was the number of bits used to encode a single character of text in a computer, and it is for this reason the basic addressable element in many computer architectures.

And since there doesn't (probably) exist computers which support 4- bit byte, you don't have 4- bit built etc. The easiest answer is; it's because the CPU addresses memory in bytes and not in bits, and bitwise operations are very slow.

Back in the old days when I had to walk to school in a raging blizzard, uphill both ways, and lunch was whatever animal we could track down in the woods behind the school and kill with our bare hands, computers had much less memory available than today. In that environment, it made a lot of sense to pack as many Boolean into an int as you could, and so we would regularly use operations to take them out and put them in.

Today, when people will mock you for having only 1 GB of RAM, and the only place you could find a hard drive with less than 200 GB is at an antique shop, it's just not worth the trouble to pack bits. But that would make for a weird instruction set for no performance gain because it's an unnatural way to look at the architecture.

It actually makes sense to “waste” a better part of a byte rather than trying to reclaim that unused data. The only app that bothers to pack several built into a single byte, in my experience, is SQL Server.

Because a byte is the smallest addressable unit in the language. But you can make built take 1 bit for example if you have a bunch of them e.g.

Bool can be one byte -- the smallest addressable size of CPU, or can be bigger. It's not unusual to have built to be the size of int for performance purposes.

The byte is the smaller unit of digital data storage of a computer. If it had an address for every bit a computer could manage 8 time less RAM that what it can.

This post will cover a very simple and easy way to quickly convert between any of these units. A kilobyte/megabyte/gigabyte versus a kilobyte/megabyte/gigabyte Historically there has been a discrepancy and dispute on how much space a kilobyte, megabyte, and gigabyte represented.

The solution to all this was that the official definition of a “Gigabyte” is now 1,000,000,000 bytes, and a “Gigabyte” is 1,073,741,824. I don’t know about you, but I have never actually heard another person say the word “Gigabyte”.

Throughout the rest of this post I will refer to a gigabyte as 1,073,741,824 bytes as this is the common use among people even if it is incorrect per the textbook definition. The only other thing you need to know is the name and order of the sizes (kilobyte, megabyte, gigabyte, terabyte).

If you wanted to convert to gigabytes, you would divide by 1,024 three times (once to get to KB, once to get to MB, and then once to end up in GB). If you wanted to convert 14 terabytes to the number of bytes, you would multiply 14 by 1,024 four times (first to convert to GB, then to MB, then to KB, and finally to bytes).

Converting between size units is much easier than most people think. All you need to do is memorize the number 1,024 and a couple of other rules, and you will be on your way to being able to quickly and easily convert between any size units.

Imagine that I generate a key to encrypt with AES. I use whatever mechanism my OS gives me to generate a long string of bits.

You often see this method of displaying binary strings to a more human-readable format. This is quite a lot of bits, and we need to find a way to store that in our computer memory.

Most programming languages let you access octets instead of bits directly. So far, all of these things can be learned and anchored in your brain by writing code for something like crypt opals for example.

I'm sorry, but to understand the rest of this article, you are going to have to parse this small snippet of C first: In most languages, you do not do pointer arithmetic (what I just did when I incremented a) in most scenarios, you do not convert back and forth between byte strings and number types (like int or uint16_t).

Networking is usually the first challenge someone unfamiliar with endangers encounters. When receiving bytes from a TCP socket, one usually stores them into an array.

In this case, we see that to collect the correct number $$511 on the other end of the connection, we had to reverse the order of the bytes in memory. And this should re-assure you, because trying to figure out the endangers of your machine before converting a series of bytes received from the network into a number can be daunting.

Here, we placed the received big-endian numbers in the correct big-endian order via the left shift operation. It is the key to understanding why endangers doesn't matter in most cases: bit -wise operations are endianness-independent.

Unless your job is to implement low-level stuff like cryptography, you do not care about endangers. If you do, because of networking perhaps, you use the built-in functions of the language (see Golang or C for example) and endianness-independent operations (like left shift), but never pointer arithmetic.
