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'.

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.

ARCHIVED: What are bits, bytes, and other units of measure for digital information?

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.

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.

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. Computer storage and memory is often measured in megabytes MB and gigabytes GB.

Bits and bytes explained

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. 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.

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.

Lesson 1: Bytes and 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.

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.

Но потом появилась группа людей, и Халохот не смог завладеть искомым предметом. Фонтейн кивнул. Агенты связались с ним, когда он находился в Южной Америке, и сообщили, что операция прошла неудачно, поэтому Фонтейн в общих чертах уже знал, что случилось. Тут вступил агент Колиандер: - Как вы приказали, мы повсюду следовали за Халохотом. В морг он не пошел, поскольку в этот момент напал на след еще какого-то парня в пиджаке и галстуке, вроде бы штатского.

 Коммандер! - позвала Сьюзан. Ответа не последовало. Сьюзан спустилась по лестнице на несколько ступенек. Горячий воздух снизу задувал под юбку. Ступеньки оказались очень скользкими, влажными из-за конденсации пара. Она присела на решетчатой площадке. - Коммандер.
