    Router R1 is a one-armed router carrying out inter-VLAN routing. A router on a stick, also known as a one-armed router, [1] [2] is a router that has a single physical or logical connection to a network. It is a method of inter-VLAN routing where one router is connected to a switch via a single cable. The router has physical connections to the ...

    Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS).

  6. Calculator input methods - Wikipedia

    en.wikipedia.org/wiki/Calculator_input_methods

    The simplest example given by Thimbleby of a possible problem when using an immediate-execution calculator is 4 × (−5). As a written formula the value of this is −20 because the minus sign is intended to indicate a negative number, rather than a subtraction, and this is the way that it would be interpreted by a formula calculator.

  7. AutoNumber - Wikipedia

    This is the size used for start+increment and random AutoNumbers. For replication ID AutoNumbers, the FieldSize property of the field is changed from long integer to Replication ID. [2] If an AutoNumber is a long integer, the NewValues property determines whether it is of the start+increment or random form. The values that this property can ...

    The finite field with p n elements is denoted GF(p n) and is also called the Galois field of order p n, in honor of the founder of finite field theory, Évariste Galois. GF( p ), where p is a prime number, is simply the ring of integers modulo p .
