 Port (computing) - Wikipedia, the free encyclopedia
In computing, a port (derived from seaport) is a connection through which data is sent and received.
Intel microprocessors generally allow one octet (8-bit byte or word) to be sent or received during each instruction.
A hardware port is an electrically wired outlet on a piece of equipment into which a plug or cable connects.

 UUID Generation and registration as OID
UUIDs forming a component of an OID are represented in ASN.1 value notation as the decimal representation of their integer value, but for all other display purposes it is more usual to represent them with hexadecimal digits with a hyphen separating the different fields within the 16-octet UUID.
UUIDs were originally used in the Network Computing System ( NCS) and later in the Open Software Foundation's Distributed Computing Environment ( DCE).
UUIDs are an octet string of 16 octets (128 bits).

 SI prefix - Wikipedia, the free encyclopedia
This article was originally based on material from the Free On-line Dictionary of Computing, which is licensed under the GFDL.
French-speaking countries often use "o" for "octet", nowadays a synonym for byte, but this is unacceptable in SI because of the risk of confusion with the zero.
The prefixes K and greater are common in computing, where they are applied to information and storage units like the bit and the byte.

 XML-Signature Syntax and Processing
If the data object is an octet stream and the next transform requires a node-set, the signature application MUST attempt to parse the octets yielding the required node-set via [XML] well-formed processing.
If the data object is a node-set and the next transform requires octets, the signature application MUST attempt to convert the node-set to an octet stream using Canonical XML [XML-C14N].
The digest algorithm is applied to the data octets of the resulting octet stream.

 NIBBLE FACTS AND INFORMATION
A nibble (or less commonly, nybble) is the computing term for the aggregation of four bits, or half an octet (an octet being an 8-bit byte).
The nibble is often called a semioctet in a networking or telecommunication context.
The term "nibble" originates from the fact that the term "byte" is a pun on the English word "bite".

is the octet string representation specified in ANSI X9.62 and IEEE P1363 of the point on the curve chosen by taking the randomly chosen secret Ka and computing Ka*P, where * is the repetition of the group addition and double operations.

(It may also be desirable to represent points in the form specified in IEEE [P1363] and ANSI [X9.62, X9.63] in the key exchange payload instead of sending only the x-coordinate as currently specified in [RFC2409].

 UUID Generation and registration as OID
UUIDs were originally used in the Network Computing System (NCS) and later in the Open Software Foundation's Distributed Computing Environment (DCE).
UUIDs are an octet string of 16 octets (128 bits).
A UUID (Universally Unique Identifier) can be used for multiple purposes, from tagging objects with an extremely short lifetime, to reliably identifying very persistent objects across a network, particularly (but not necessarily) as part of an ASN.1 object identifier (OID) value, or in a Uniform Resource Name (URN).

 255 (number) - TheBestLinks.com - Bit, Byte, Central processing unit, Color, ...
This is the maximum value representable by an eight-digit binary number, and therefore the maximum representable by an unsigned 8-bit byte (the most common size of byte, also called octet), the smallest common variable size used in high level programming languages (bit being smaller, but rarely used for value storage).
Other common numbers in computing include 127, 32767, 65535, 2147483647 and 4294967295—all of which are 2 raised to a power, minus 1.
255 is a special number in some tasks having to do with computing.

In computing, Unicode is the international standard whose goal is to provide the means to encode the text of every document people want to store in computers.
Code page is the traditional IBM term used for a specific character encoding table: a mapping in which a sequence of bits, usually a single octet representing integer values 0 through 255, is associated with a specific character.

 RFC 1771 (rfc1771) - A Border Gateway Protocol 4 (BGP-4)
BGP Identifier: This 4-octet unsigned integer indicates the BGP Identifier of the sender.
Whenever an authentication mechanism is specified for use within BGP, three things must be included in the specification: - the value of the Authentication Code which indicates use of the mechanism, - the form and meaning of the Authentication Data, and - the algorithm for computing values of Marker fields.
Note that quite often BGP, as specified in RFC 1105, is referred to as BGP-1, BGP, as specified in RFC 1163, is referred to as BGP-2, BGP, as specified in RFC1267 is referred to as BGP-3, and BGP, as specified in this document is referred to as BGP-4.

 RFC 944
The only change noted for the UDP specification is a minor clarification that if in computing the checksum a padding octet is used for the computation it is not transmitted or counted in the length.
While the issues discussed may not be directly relevant to the research problems of the DARPA community, they may be interesting to a number of researchers and implementors.

 RFC 792 (rfc792) - Internet Control Message Protocol
The first octet of the data portion of the datagram is a ICMP type field; the value of this field determines the format of the remaining data.
For computing the checksum, the checksum field should be zero.
ICMP messages are sent in several situations: for example, when a datagram cannot reach its destination, when the gateway does not have the buffering capacity to forward a datagram, and when the gateway can direct the host to send traffic on a shorter route.

 SI prefix - Wikipedia, the free encyclopedia
The prefixes K and greater are common in computing, where they are applied to information and storage units like the bit and the byte.
French-speaking countries often use "o" for "octet", nowadays a synonym for byte, but this is unacceptable in SI because of the risk of confusion with the zero.
Thus the SI prefixes provide steps of a factor one million instead of one thousand in the case of an exponent 2, of a billion in the case of an exponent 3, etc. As a result large numbers may be needed, even if the prefixes are fully used.

This is the maximum value representable by an eight-digit binary number, and therefore the maximum representable by an unsigned 8-bit byte (the most common size of byte, also called octet), the smallest common variable size used in high level programming languages (bit being smaller, but rarely used for value storage).

This number could be interpreted by a computer as -1 if a programmer is not careful about which 8-bit values are signed and unsigned, and the two's complement representation of -1 in a signed byte is equal to that of 255 in an unsigned byte.

 Integral data type - Wikipedia
The integral data types (so called because they are most frequently used to represent integers) of computing generally consist of some number of bits (usually a power of two) treated as a unit of storage or manipulation.
A byte, usually called an octet in a networking context, is used to specify the size or amount of computer memory or storage, regardless of the type of data represented.
Additional data types, such as bit-fields and extended-precision integers, found in high level programming languages are not discussed here.

 RFC 1051 - Standard for the transmission of IP datagrams and ARP packets over ARCNET networks. P.A. Prindeville.
As required by Datapoint Corporation, the first octet of the data field is reserved for the network layer protocol identification (the "system code" in Datapoint nomenclature), and must contain the value 240 (F0 hex) for IP or 241 (F1 hex) for ARP.
Acknowledgements The author wishes to express thanks to Robert Craig of the McGill University Computing Centre and Bruce Hughes of Datapoint Corporation for their generous support of facilities and information.
