The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer   and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily-sized bytes from the common 8-bit definition, network protocol documents such as The Internet Protocol RFC refer to an 8-bit byte as an octet. The first bit is number 0, making the eighth bit number 7. The size of the byte has historically been hardware -dependent and no definitive standards existed that mandated the size.
Every file on a computer uses a certain amount of resources when sent over the internet or stored. Keeping mind of your kilobytes kB and megabytes MB can prevent problems and produce a smoother online experience. This GreenNet guide is here to help you tell the whales from the minnows. Computer resources do have physical limits to their capacities, even if the idea of computer resources can be scaled up indefinitely. So we really want to think of the sizes of files in a tidy, minimalist way and thereby make the most of the resources we already have.
In computing and telecommunications , a unit of information is the capacity of some standard data storage system or communication channel , used to measure the capacities of other systems and channels. In information theory , units of information are also used to measure the entropy of random variables and information contained in messages. The most commonly used units of data storage capacity are the bit , the capacity of a system that has only two states, and the byte or octet , which is equivalent to eight bits. Multiples of these units can be formed from these with the SI prefixes power-of-ten prefixes or the newer IEC binary prefixes power-of-two prefixes. In , Ralph Hartley observed a fundamental storage principle,  which was further formalized by Claude Shannon in the information that can be stored in a system is proportional to the logarithm of N possible states of that system, denoted log b N.

Can't tell your bits from your bytes? 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. Aren't they the same thing? Actually no, there's a big difference between a bit and a byte. A byte is much bigger — eight times bigger, to be exact, with eight bits in every byte.
In this lesson students are introduced to the standard units for measuring the sizes of digital files, from a single byte, all the way up to terabytes and beyond. Students are introduced to the units kilobyte, megabyte, gigabyte, and terabyte, and research the sizes of files they make use of every day, using the appropriate terminology. This lesson foreshadows an investigation of compression as a means for combatting the rapid growth of digital data. And many computer systems will require you store even more than that. Messages sent over the Internet are also typically structured as messages with byte-offsets. Paralleling the explosion of computing power and speed, the sheer size of the digital data now created and consumed every day is staggering.
Lesson 1: Bytes and File Sizes
Memory of a Computer is any physical device that is capable of storing information whether it is large or small and stores it temporarily or permanently. For example, Random Access Memory RAM , is a type of volatile memory that stores information for a short interval of time, on an integrated circuit used by the operating system. Memory can be either volatile or non-volatile. Volatile memory is a type of memory that loses its contents when the computer or hardware device is switched off.
