What does a byte represent in the common computer

Problems with byte order are frustrating, and I want to spare you the grief I experienced. Here's the key: • Problem: Computers speak different languages, like people. Some write data "left-to-right" and others "right-to-left". • A machine can read its own data just fine - problems happen when one computer stores data and a different type tries to read it. • Solutions • Agree to a common format (i.e., all network traffic follows a single format), or • Always include a header that describes the format of the data. If the header appears backwards, it means data was stored in the other format and needs to be converted. Numbers vs. Data The most important concept is to recognize the difference between a number and the data that represents it. A number is an abstract concept, such as a count of something. You have ten fingers. The idea of "ten" doesn't change, no matter what representation you use: ten, 10, diez (Spanish), ju (Japanese), 1010 (binary), X (Roman numeral)... these representations all point to the same concept of "ten". Contrast this with data. Data is a physical concept, a raw sequence of bits and bytes stored on a computer. Data has no inherent meaning and must be interpreted by whoever is reading it. Data is like human writing, which is simply marks on paper. There is no inherent meaning in these marks. If we see a line and a circle (like this: |O) we may interpret it to mean "ten". But we assumed the marks referred to a number. They could have been the letters...

Table of Contents How exactly do you gauge just how much space a gigabyte, a terabyte, or even a petabyte describes? What Is a Byte? To understand how the larger blocks of memory work, it’s important to build an appreciation for the smaller blocks of space that those larger ones are made from. In simple terms, a single byte is typically eight binary digits. A binary digit is a 1 or a 0, which in very old computers literally represented a switch that was on or off. There are some computer systems that have bytes of other lengths, but most modern computers today are based on an eight-bit byte binary system. Those eight bits (a byte) usually represent a character like a letter or number. Bytes can also represent symbols that represent one piece of a larger object like an image. Since a “byte” is the smallest unit of data, then other names are needed for larger units of data made up of even more bits. The important thing to keep in mind is that all the larger units are made up of a fixed number of bytes, and each byte typically contains eight bits. As you start stacking up more bytes, you can determine the name of the unit based on the number of bytes. A Kilobyte is 1,024 Bytes You would think that since the prefix “kilo” typically means 1,000, that kilobyte would have 1,000 bytes. The reality is that since computers store data using the binary system, and the binary system is based on powers of 2, the actual number of bytes is 1,024. You can see this when you look at how the ...

In the chart above, the column heading indicates the first 3 bits and the row heading indicates the final 4 bits. The very first character is "NUL", encoded as 0000000 \texttt 0 0 0 0 0 0 0 start text, 0, end text, start text, 0, end text, start text, 0, end text, start text, 0, end text, start text, 0, end text, start text, 0, end text, start text, 0, end text . The first 32 codes represent "control characters," characters which cause some effect besides printing a letter. "BEL" (encoded in binary as 0000111 \texttt 0 0 0 0 101 start text, 0, end text, start text, 0, end text, start text, 0, end text, start text, 0, end text, start text, 101, end text ) represented an enquiry, a request for the receiving station to identify themselves. The control characters were originally designed for teleprinters and telegraphy, but many have been re-purposed for modern computers and the Internet—especially "CR" and "LF".

( Binar Y Tabl E) The common unit of computer storage from desktop computer to mainframe. It is made up of eight binary digits (bits). A ninth bit may be used in the memory (RAM) circuits as a parity bit for error checking. See A byte holds one alphabetic character such as the letter A, a dollar sign or decimal point. For numeric data, one byte holds one decimal digit (0-9), two "packed decimal" digits (00-99) or a binary number from 0 to 255. See Bit, Byte and Nibble The term "bit" for "binary digit" was coined in the 1940s. In the 1950s, IBM coined the terms "byte" and "nibble" (half a byte) to maintain the mastication theme "bit, bite, nibble." From Bite to Byte IBM coined the term in the mid-1950s to mean the smallest addressable group of bits in a computer, which was originally not eight. The first spelling of the word was "bite," but the y was added to avoid misspelling between "bit" and "bite." Byte Specifications Drives and memory (RAM) are rated in bytes. For example, a 512-gigabyte (512GB) drive stores 512 billion characters of program instructions and data permanently, while eight gigabytes (8GBs) of RAM holds eight billion temporarily. The first hard drives in early personal computers held 5MB, and RAM was 64K. See Eight Bits Make Up One Byte There are eight binary digits (bits) in a byte, but there can also be nine bits per byte in RAM cells that include error correction (see The Bytes Got Really Small! In 1991, this hard drive held 670 megabytes. By 2018, the...

Data In The Computer Data In The Computer Representing Data We have all seen computers do seemingly miraculous things with all kinds of sounds, pictures, graphics, numbers, and text. It seems that we can build a replica of parts of our world inside the computer. You might think that this amazing machine is also amazingly complicated - it really is not. In fact, all of the wonderful multi-media that we see on modern computers is all constructed from simple ON/OFF switches - millions of them - but really nothing much more complicated than a switch. The trick is to take all of the real-world sound, picture, number etc data that we want in the computer and convert it into the kind of data that can be represented in switches, as shown in Figure 1. Figure 1: Representing Real-World Data In The Computer Computers Are Electronic Machines. The computer uses electricity, not mechanical parts, for its data processing and storage. Electricity is plentiful, moves very fast through wires, and electrical parts fail much less frequently than mechanical parts. The computer does have some mechanical parts, like its disk drive (which are often the sources for computer failures), but the internal data processing and storage is electronic, which is fast and reliable (as long as the computer is plugged in). Electricity can flow through switches: if the switch is closed, the electricity flows; if the switch is open, the electricity does not flow. To process real-world data in the computer, we ne...
