AC

Answer explanation

Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the

ACL

Answer explanation

· An access control list (ACL) contains rules that grant or deny access to certain digital environments. There are two types of ACL

ADF

Answer explanation

What does Automatic Document Feeder (ADF) mean? An automatic document feeder (ADF) is a feature in printers, photocopiers, fax machines or scanners wherein a stack of paper put into the machine and is then automatically fed through it, allowing the user to print, scan or copy without having to manually place each page into the machine.

AES

Answer explanation

The Advanced Encryption Standard (AES), also known by its original name Rijndael (Dutch pronunciation: [ˈrɛindaːl]),^[5] is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001.^[6]

AES is a variant of the Rijndael block cipher^[5] developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, who submitted a proposal^[7] to NIST during the AES selection process.^[8] Rijndael is a family of ciphers with different key and block sizes. For AES, NIST selected three members of the Rijndael family, each with a block size of 128 bits, but three different key lengths: 128, 192 and 256 bits.

AP

Answer explanation

In typical wireless networking implementations, an access point is a device connected to a wired network, such as an Ethernet network. The AP is a transceiver, transmitting and receiving signals using either direct sequencing or frequency hopping methods in spread spectrum communication technologies. It provides a point of access to the wired network for mobile computers.

APIPA

Answer explanation

APIPA stands for Automatic Private IP Addressing (APIPA). It is a feature or characteristic in operating systems (eg. Windows) which enables computers to self-configure an IP address and subnet mask automatically when their DHCP(Dynamic Host Configuration Protocol) server isn’t reachable. The IP address range for APIPA is (169.254.0.1 to 169.254.255.254) having 65, 534 usable IP addresses, with the subnet mask of 255.255.0.0.

ARP

Answer explanation

The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite. ARP was defined in 1982 by RFC 826,^[1] which is Internet Standard STD 37.

AUP

Answer explanation

An acceptable use policy (AUP), acceptable usage policy or fair use policy is a set of rules applied by the owner, creator or administrator of a computer network website, or service that restricts the ways in which the network, website or system may be used and sets guidelines as to how it should be used. AUP documents are written for corporations,^[1] businesses, universities,^[2] schools,^[3] internet service providers (ISPs),^[4] and website owners,^[5] often to reduce the potential for legal action that may be taken by a user, and often with little prospect of enforcement.

BIOS

Answer explanation

In computing, BIOS (/ˈbaɪɒs, -oʊs/, BY-oss, -⁠ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).^[1] The BIOS firmware comes pre-installed on an IBM PC or IBM PC compatible's system board and exists in some UEFI-based systems to maintain compatibility with operating systems that do not support UEFI native operation.^[2][3] The name originates from the Basic Input/Output System used in the CP/M operating system in 1975.^[4][5] The BIOS originally proprietary to the IBM PC has been reverse engineered by some companies (such as Phoenix Technologies) looking to create compatible systems. The interface of that original system serves as a de facto standard.

BSOD

Answer explanation

The Blue Screen of Death (BSoD), Blue screen error, Blue Screen, fatal error, or bugcheck, and officially known as a Stop error,^[1][2][3] is a critical error screen displayed by the Microsoft Windows or ReactOS operating systems in the event of a fatal system error.

The Blue Screen of Death indicates a system crash, in which the operating system has reached a critical condition where it can no longer operate safely. Possible issues include hardware failure, an issue with or without a device driver, or unexpected termination of a crucial process or thread.
