All Internet service providers must retain the following data for six months: type of the connections (telephone, xDSL, Cable, permanent line etc.) and if known login data, address information of the origin (MAC address, telephone number), name, address and occupation of the user and duration of the connection from beginning to end
The external memory on the right is unbounded. External memory algorithms are analyzed in an idealized model of computation called the external memory model (or I/O model, or disk access model). The external memory model is an abstract machine similar to the RAM machine model, but with a cache in addition to main memory.
Digital computers, in particular, make use of two forms of memory known as RAM or ROM and although the most common form today is RAM, designed to retain data while the computer is powered on, this was not always the case. Nor is active memory the only form used; passive memory devices are now in common use in digital cameras.
The algorithm is suitable for network cache applications such as information-centric networking (ICN), content delivery networks (CDNs) and distributed networks in general. TLRU introduces a term: TTU (time to use), a timestamp of content (or a page) which stipulates the usability time for the content based on its locality and the content ...
In computing, interleaved memory is a design which compensates for the relatively slow speed of dynamic random-access memory (DRAM) or core memory, by spreading memory addresses evenly across memory banks. That way, contiguous memory reads and writes use each memory bank in turn, resulting in higher memory throughput due to reduced waiting for ...
Memory organization is an aspect of computer architecture that is concerned with the storage and transfer of data and programs [1]. There are several ways to organise memories with respect to the way they are connected to the cache: one-word-wide memory organisation; wide memory organisation; interleaved memory organisation; independent memory ...
Uniform memory access (UMA) is a shared memory architecture used in parallel computers.All the processors in the UMA model share the physical memory uniformly. In an UMA architecture, access time to a memory location is independent of which processor makes the request or which memory chip contains the transferred data.
Although dynamic memory is only specified and guaranteed to retain its contents when supplied with power and refreshed every short period of time (often 64 ms), the memory cell capacitors often retain their values for significantly longer time, particularly at low temperatures. [54]
