Addressable Screen
Addressable may refer to an address. Alternatively it could refer to one of the following: * Addressability, the ability of a digital device to individually respond to a message sent to many similar devices * Content-addressable memory, a special type of computer memory used in certain very-high-speed searching applications * Total addressable market, used to reference the revenue opportunity available for a product or service {{disambiguation ...

Address
An address is a collection of information, presented in a mostly fixed format, used to give the location of a building, apartment, or other structure or a plot of land, generally using political boundaries and street names as references, along with other identifiers such as house or apartment numbers and organization name. Some addresses also contain special codes, such as a postal code, to make identification easier and aid in the routing of mail. Addresses provide a means of physically locating a building. They are used in identifying buildings as the end points of a postal system and as parameters in statistics collection, especially in census-taking and the insurance industry. Address formats are different in different places, and unlike latitude and longitude coordinates, there is no simple mapping from an address to a location. History Until the 18th and 19th centuries, most houses and buildings were not numbered. Street naming and numbering began under the age of Enl ...

Addressability
Addressability is the ability of a digital device to individually respond to a message sent to many similar devices. Examples include pagers, mobile phones and set-top boxes for pay TV. Computer networks are also addressable, such as via the MAC address on Ethernet network cards, and similar networking protocols like Bluetooth. This allows data to be sent in cases where it is impractical (or impossible, such as with wireless devices) to control exactly where or to which devices the message is physically sent. In the case of simple hardware devices like the pager, the address is simply the electronic serial number (and later IMEI/MEID) in its firmware, or physically manufactured into its circuitry. In the case of GSM mobile phones, it also includes the subscriber identity module, which is also present as a smart card on satellite TV receivers, or a different PCMCIA CableCARD for cable TV. Addressing and encryption are used together for conditional access to different TV chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Content-addressable Memory
Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory or associative storage and compares input search data against a table of stored data, and returns the address of matching data. CAM is frequently used in networking devices where it speeds up forwarding information base and routing table operations. This kind of associative memory is also used in cache memory. In associative cache memory, both address and content is stored side by side. When the address matches, the corresponding content is fetched from cache memory. History Dudley Allen Buck invented the concept of content-addressable memory in 1955. Buck is credited with the idea of ''recognition unit''. Hardware associative array Unlike standard computer memory, random-access memory (RAM), in which the user supplies a memory address and the RAM returns the data word stored at that address, a CAM is designed such ...
