When talking about comptia a+ 1001 and 1002 it is important to know there are a lot of acronyms. In any industry there is host of terms that are used. In test and in the field these acronyms will be all the time. In this article we will go through some the acronyms that will be seen on exam. In the end there will be practice exam to review these acronyms.
AC Alternating current
Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction.
ACL Access Control list
An access–control list (ACL), with respect to a computer file system, is a list of permissions attached to an object. An ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects. Each entry in a typical ACL specifies a subject and an operation.
ACPI Advanced Configuration Power Interface
ACPI (Advanced Configuration and Power Interface) is an industry specification for the efficient handling of power consumption in desktop and mobile computers. ACPI specifies how a computer’s basic input/output system, operating system, and peripheral devices communicate with each other about power usage.
ADF Automatic Document Feeder
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.
ADSL Asymmetrical Digital Subscriber line
Asymmetric digital subscriber line is a type of digital subscriber line technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL differs from the less common symmetric digital subscriber line.
AES Advanced Encryption Standard
The Advanced Encryption Standard, also known by its original name Rijndael, is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology in 2001
AHCI Advanced Host Controller Interface
Advanced Host Controller Interface, or AHCI, is a technical standard for an interface that enables software to communicate with Serial ATA (SATA) devices. These peripheral component interconnect (PCI)-class devices move data between system memory and SATA storage media.
AP Access Point
In computer networking, a wireless access point, or more generally just access point, is a networking hardware device that allows other Wi-Fi devices to connect to a wired network. The AP usually connects to a router as a standalone device, but it can also be an integral component of the router itself.
APIPA Automatic Private Internet Protocol Addressing
Automatic Private IP Addressing (APIPA) is a feature of Windows-based operating systems (included in Windows 98, ME, 2000, and XP) that enables a computer to automatically assign itself an IP address when there is no Dynamic Host Configuration Protocol (DHCP) server available to perform that function.
APM Advance Power Management
Advanced Power Management (APM) is an application programming interface (API) developed jointly by Microsoft
and Intel. It allows an operating system to communicate with the computer’s BIOS in order to achieve efficient power management.
ARP Adress Resolution Protocol
The address resolution protocol (arp) is a protocol used by the Internet Protocol (IP) [RFC826], specifically IPv4, to map IP network addresses to the hardware addresses used by a data link protocol. The protocol operates below the network layer as a part of the interface between the OSI network and OSI link layer.
ASR Automated System Recovery
Automated system recovery (ASR) is a feature of the Windows XP operating system that can be used to simplify recovery of a computer’s system or boot volumes. ASR consists of two parts: an automated backup, and an automated restore. The backup portion can be accessed in the Backup utility under System Tools.
ATA Advanced Technology Attachment
Advanced Technology Attachment (ATA) is a standard physical interface for connecting storage devices within a computer. ATA allows hard disks and CD-ROMs to be internally connected to the motherboard and perform basic input/output functions.
ATAPI Advanced Technology Attachment Interface
ATAPI, Advanced Technology Attachment with Packet Interface is the standard interface (type of connection) used to connect hard drives, CD-ROM drives and other components like RAM, motherboard inside the CPUs of personal computers.
ATM Asynchronous Transfer Mode
Asynchronous transfer mode (ATM) is a switching technique used by telecommunication networks that uses asynchronous time-division multiplexing to encode data into small, fixed-sized cells. This is different from Ethernet or internet, which use variable packet sizes for data or frames.
ATX Advanced technology Extended
ATX is a motherboard and power supply configuration specification developed by Intel in 1995 to improve on previous de facto standards like the AT design.
AUP Acceptable Use Policy
An acceptable use policy, acceptable usage policy or fair use policy, is a set of rules applied by the owner, creator or administrator of a network, website, or service, that restrict the ways in which the network, website or system may be used and sets guidelines as to how it should be used.
A/V Audio Video
Audio Video (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services and live theater productions.
BD-R Blu-ray Disc Recordable
Blu-ray or Blu-ray Disc is a digital optical disc data storage format. It was designed to supersede the DVD format, and is capable of storing several hours of video in high-definition and ultra high-definition resolution.
Now that we have an introduction to some acronyms we will see on day to day basis. We cannot just look at the words and expect to know them by heart now can we. We need to practice these words and drill them till we are comfortable.
