In computer security, an access-control list ( ACL) is a list of permissions [ a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [ 1] Each entry in a typical ACL specifies a subject and an operation.
Network topology is the arrangement of the elements ( links, nodes, etc.) of a communication network. [ 1][ 2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, [ 3] industrial fieldbusses and computer networks .
Local area network. A local area network ( LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. [ 1] By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication ...
A mesh basic service set ( MBSS) is a self-contained network of mesh stations that share a mesh profile, defined in 802.11s. [ 9] Each node may also be an access point hosting its own basic service set, for example using the mesh BSS to provide Internet access for local users. In such a system, the BSS created by the access point is distinct ...
Physical Address Extension. In computing, Physical Address Extension ( PAE ), sometimes referred to as Page Address Extension, [ 1] is a memory management feature for the x86 architecture. PAE was first introduced by Intel in the Pentium Pro, and later by AMD in the Athlon processor. [ 2] It defines a page table hierarchy of three levels ...
In today's technology, random-access memory takes the form of integrated circuit (IC) chips with MOS (metal–oxide–semiconductor) memory cells. RAM is normally associated with volatile types of memory where stored information is lost if power is removed. The two main types of volatile random-access semiconductor memory are static random ...
Wide area network. A wide area network ( WAN) is a telecommunications network that extends over a large geographic area. Wide area networks are often established with leased telecommunication circuits. [ 1] Businesses, as well as schools and government entities, use wide area networks to relay data to staff, students, clients, buyers and ...
exFAT ( Extensible File Allocation Table) is a file system introduced by Microsoft in 2006 and optimized for flash memory such as USB flash drives and SD cards. [ 6] exFAT was proprietary until 28 August 2019, when Microsoft published its specification. [ 7] Microsoft owns patents on several elements of its design.
