Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [1] The technique was originally used to bypass the need to assign a new address to every host when a network was moved, or when ...
Port forwarding. In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall. This technique is most commonly used to ...
Program-specific information (PSI) is metadata about a program (channel) and part of an MPEG transport stream. The PSI data as defined by ISO/IEC 13818-1 (MPEG-2 Part 1: Systems) includes four tables: The MPEG-2 specification does not specify the format of the CAT and NIT. PSI is carried in the form of a table structure.
Linux kernel version history. This article documents the version history of the Linux kernel. Each major version – identified by the first two numbers of a release version – is designated one of the following levels of support: Supported till next stable version. Long-term support (LTS); maintained for a few years [1]
The page attribute table (PAT) is a processor supplementary capability extension to the page table format of certain x86 and x86-64 microprocessors. Like memory type range registers (MTRRs), they allow for fine-grained control over how areas of memory are cached , and are a companion feature to the MTRRs.
The Intel Performance Acceleration Technology (PAT) is technology built onto Intel i875 Canterwood mainboards and other Pentium 4 based motherboards that based on the Intel D875PBZ reference board. Performance Acceleration Technology delivers additional system-level performance by optimizing memory access between CPU and system memory, allowing ...
Personal access token. In computing, a personal access token (or PAT) is a string of characters that can be used to authenticate a user when accessing a computer system instead of the usual password. [1][2][3][4] Though associated with a single account, multiple PATs may be created, and can be manipulated independently of the password ...
Process analytical technology (PAT) has been defined by the United States Food and Drug Administration (FDA) as a mechanism to design, analyze, and control pharmaceutical manufacturing processes through the measurement of critical process parameters (CPP) which affect the critical quality attributes (CQA). The concept aims at understanding the ...
