  3. Java bytecode - Wikipedia

    en.wikipedia.org/wiki/Java_bytecode

    Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte , hence the name bytecode , making it a compact form of data .

  4. List of IP protocol numbers - Wikipedia

    en.wikipedia.org/wiki/List_of_IP_protocol_numbers

    This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.

  5. Binary translation - Wikipedia

    en.wikipedia.org/wiki/Binary_translation

    Binary translation is motivated by a lack of a binary for a target platform, the lack of source code to compile for the target platform, or otherwise difficulty in compiling the source for the target platform. Statically recompiled binaries run potentially faster than their respective emulated binaries, as the emulation overhead is removed.

  6. Code conversion - Wikipedia

    en.wikipedia.org/wiki/Code_conversion

    Conversion of signals, or groups of signals, in one code into corresponding signals, or groups of signals, in another code. 2. A process for converting a code of some predetermined bit structure, such as 5, 7, or 14 bits per character interval, to another code with the same or a different number of bits per character interval.

  7. Source-to-source compiler - Wikipedia

    en.wikipedia.org/wiki/Source-to-source_compiler

    The Runtime Converter is an automatic tool which converts PHP source code into Java source code. There is a Java runtime library for certain features of the PHP language, as well as the ability to call into the PHP binary itself using JNI for PHP standard library and extension function calls.

  8. IP address - Wikipedia

    en.wikipedia.org/wiki/IP_address

    The term subnet mask is only used within IPv4. Both IP versions however use the CIDR concept and notation. In this, the IP address is followed by a slash and the number (in decimal) of bits used for the network part, also called the routing prefix. For example, an IPv4 address and its subnet mask may be 192.0.2.1 and 255.255.255.0, respectively.

  9. Internet checksum - Wikipedia

    en.wikipedia.org/wiki/Internet_checksum

    The Internet checksum, [1] [2] also called the IPv4 header checksum is a checksum used in version 4 of the Internet Protocol (IPv4) to detect corruption in the header of IPv4 packets. It is carried in the IPv4 packet header, and represents the 16-bit result of the summation of the header words. [3] The IPv6 protocol does not use header checksums.
