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.

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 [1] [2] 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.

Data Measurement Chart

A bit is a binary digit, the smallest increment of data on a computer. A bit can hold only one of two values: 0 or 1, corresponding to the electrical values of off or on, respectively. Because bits are so small, you rarely work with information one bit at a time. Bits are usually assembled into a group of eight to form a byte. A kilobyte KB is 1, bytes, not one thousand bytes as might be expected, because computers use binary base two math, instead of a decimal base ten system.

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. RAM is an example of a volatile memory i.

Difference Between Bits and Bytes

By: Marshall Brain. If you have used a computer for more than five minutes, then you have heard the words bits and bytes. Both RAM and hard disk capacities are measured in bytes, as are file sizes when you examine them in a file viewer. You might hear an advertisement that says, "This computer has a bit Pentium processor with 64 megabytes of RAM and 2. In this article, we will discuss bits and bytes so that you have a complete understanding. The easiest way to understand bits is to compare them to something you know: digits. A digit is a single place that can hold numerical values between 0 and 9.

How Bits and Bytes Work

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.

Understanding file sizes

A bit is the smallest unit of data in a computer, it is a single binary digit; it means that the digit can have either of two values and the two values are 0 and 1. Bits are used to encode a single unit of digital information. Computers operate on this base 2 number system. Computer uses bits as bits can easily be implemented with current electronic technology. Bit is basically a short name for binary digit.

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.

Computers are electronic devices, and they only work with discrete values. So, in the end, any type of data that the computer wants to handle is converted to numbers. However, computers do not represent numbers in the same way that we humans do. To represent numbers, we use the decimal system that makes use of 10 digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. In the electronics that make up the computer, a bit can be represented by having two voltages. For instance, a colour can be described by how much red, green, and blue go into making up that colour.


Most current machines use 32 bits (4 bytes) words. ○ Limits High-end systems use 64 bits (8 bytes) words Symmetric difference { 2, 3, 4, 5 }.


What is the Difference between a Bit and a Byte?

What is a Bit

Скажите, что мы сдаемся. Немедленно! - Джабба достал из кармана мобильник.  - Давайте мне его номер. Я сам позвоню этому… - Не беспокойтесь, - прошептала Сьюзан.  - Танкадо мертв. Все замерли в изумлении. Возможные последствия полученного известия словно пулей пронзили Джаббу.

Они, вполне естественно, хотят предотвратить распространение Цифровой крепости, поэтому послали на поиски ключа человека по имени Дэвид Беккер. - Откуда вам это известно. - Это не имеет отношения к делу. Нуматака выдержал паузу. - А если мистер Беккер найдет ключ. - Мой человек отнимет. - И что .

Он знал, что для эмоций еще будет время, а теперь пора отправляться домой. Он попробовал встать, но настолько выбился из сил, что не смог ступить ни шагу и долго сидел, изможденный вконец, на каменных ступеньках, рассеянно разглядывая распростертое у его ног тело. Глаза Халохота закатились, глядя в пустоту. Странно, но его очки ничуть не пострадали. Странные очки, подумал Беккер, увидев проводок, который тянулся от ушных дужек к коробочке, пристегнутой к брючному ремню. Но он настолько устал, что ему было не до любопытства.

Выслушав подробности, он долго молчал. Дэвид, - сказал наконец Стратмор мрачным голосом, - обнаружение этого кольца - вопрос национальной безопасности.

 Конечно. Но я думаю, что одно с другим может быть связано самым непосредственным образом. Сьюзан отказывалась его понимать.
