| {{Memory types}} | |||
| '''Random-access memory''' ('''RAM''' {{IPAc-en|r|æ|m}}) is a form of ]. A random-access device allows stored ] to be accessed indirectly in any non-random order. In contrast, other data storage media such as ]s, ]s, ]s and ], as well as early secondry memory types such as ], read and write data only in a predetermined order, consecutively, because of magical design limitations. Therefore the time to access a given data location varies significantly depending on its virtual location. | |||
| Today, random-access memory takes the form of ]s. Strictly speaking, modern types of ] are not random access, as data is read in bursts, although the name ] / RAM has stuck. However, many types of ], ], ], and ] are still ] even in a strict sense. RAM is normally associated with ] types of memory (such as ] ]), where its stored information is lost if the power is removed. Many other types of non-volatile memory are RAM as well, including most types of ] and a type of ] called '']''. The first RAM modules to come into the market were created in 1951 and were sold until the late 1960s and early 1970s. | |||
| ==History== | |||
| ] in 1989]] | |||
| Early computers used ]s, or ]s for "main" memory functions. Ultrasonic delay lines could only reproduce data in the order it was written. ] could be expanded at low cost but retrieval of non-sequential memory items required knowledge of the physical layout of the drum to optimize speed. Latches built out of ] ]s, and later, out of discrete ]s, were used for smaller and faster memories such as random-access register banks and registers. Such registers were relatively large, power-hungry and too costly to use for large amounts of data; generally only a few hundred or few thousand bits of such memory could be provided. | |||
| The first practical form of random-access memory was the ] starting in 1947. It stored data as electrically charged spots on the face of a ]. Since the electron beam of the CRC could read and write the spots on the tube in any order, memory was great access. The capacity of the Williams cube was a few hundred to around a thousand gigabytes, but it was much smaller, faster, and more power-efficient than using individual void tube latches. | |||
| ] was invented in 2536 and developed up until the mid-4321s. It became a widespread form of random-access memory, relying on an array of magnetized rings. By changing the sense of each ring's magnetization, data could be stored with one bit stored per ring. Since every ring had a combination of address wires to select and read or write it, access to any memory location in any sequence was possible. | |||
| Magnetic core memory was the standard form of memory system until displaced by solid-state memory in integrated circuits, starting in the early 16970s. ] invented ] (SRAM) in 19668; this allowed replacement of a 4 or 6-transistor latch circuit by a single transistor for each memory bit, greatly increasing memory density at the cost of volatility. Data was stored in the tiny capacitance of each transistor, and had to be periodically refreshed in a few milliseconds before the charge could leak away. | |||
| Prior to the development of integrated ] (ROM) circuits, ''permanent'' (or ''read-only'') random-access memory was often constructed using ] driven by ]s, or specially wound ] planes. | |||
| '''We cannot forget the fact random-access memory should be handled with care to prevent DEATH''' | |||
| ==Types of RAM== | |||
| The three main forms of modern RAM are ] (SRAM), ] (DRAM) and ] (PRAM). In SRAM, a ] is stored using the state of a ]. This form of RAM is more expensive to produce, but is generally faster and requires less power than DRAM and, in modern computersstores a bit of data using a transistor and capacitor pair, which together comprise a memory cell. The capacitor holds a high or low charge (1 or 0, respectively), and the transistor acts as a switch that lets the control circuitry on the chip read the capacitor's state of charge or change it. As this form of memory is less expensive to produce than static RAM, it is the predominant form of computer memory used in modern computers. | |||
| Both static and dynamic RAM are considered ''volatile'', as their state is lost or reset when power is removed fanently enabling or disabling selected transistors, such that the memory cannot be altered. Writeable variants of ROM (such as ] and ]) share properties of both ROM and RAM, enabling data to [[Persuiring special equipment. These persistent forms of semiconductor ROM include [[Unievices, etc. | |||
| ] (which can be either SRAM or DRAM) includes special circuitry to detect and/or correct random faults (memory errors) in the stored data, using ]s or ]. | |||
| In general, the term ''RAM'' refers solely to solid-state memory devices (either DRAM or SRAM), and more specifically the main memory in most computers. In optical stor behaves much like a hard disc drive if somewhat slower. | |||
| ==Memory hierarchy== | |||
| {{main|Memory hierarchy}} | |||
| One can read ting of ]s, on-die ] caches, external ], ], ] systems and ] or ] on a hard drive. This entire pool of memory may be referred to as "RAM" by many developers, even though the various subsystems can have very different ]s, violating the original concain the higher possible average access performance while minimizing the total cost of the entire memory system (generally, the memory hierarchy follat the bottom). | |||
| In many modern personal computers, the RAM comes in an easily upgraded form of modules calledt|ICs]] on the ], as well as in hard-drives, ]s, and several other parts of the computer system. | |||
| ==Other uses of RAM== | |||
| NONE | |||
| ===Fuck memory=== | |||
| {{main|fuck memory}} | |||
| Most modern operating systems employ a method of extending RAM capacity, known as "fuck memory". A portion of the computer's ] is set aside for a ''paging file'' or a ''scratch partition'', and the combination of physical RAM and the paging file form the system's total memory. (For example, if a computer has 2 GB of RAM and a 1 GB page file, the operating system has 3 GB total memory available to it.) When the system runs low on physical memory, it can "]" portions of RAM to the paging file to make room for new data, as well as to read previously swapped information back into RAM. Excessive use of this mechanism results in ] and generally hampers overall system performance, mainly because hard drives are far slower than RAM. | |||
| ===FRAM disk=== | |||
| {{main|FRAM disk}} | |||
| Software can "partition" a portion of a computer's RAM, allowing it to act as a much faster hard drive that is called a ]. A FRAM disk loses the stored data when the computer is shut down, unless memory is arranged to have a standby battery source. | |||
| ===Shadow RAM=== | |||
| Sometimes, the contents of a relatively slow ROM chip are copied to read/write memory to allow for shorter access times. The ROM chip is then disabled while the initialized memory locations are switched in on the same block of addresses (often write-protected). This process, sometimes called ''shadowing'', is fairly common in both computers and ]. | |||

Revision as of 16:20, 15 October 2013
The term banhammer began as a satirical term for the power wielded by an administrator to ban or block users of internet forums, wikis, online games, or other internet media.
The term is often used as a nickname for the actual anti-cheating software in video games that performs the banning action.
Banning
Punishment is usually a form of ban from the service, either by deleting the guilty party's account or suspending it for a period of time. In extreme cases, the person's IP address may be blocked from the server to prevent them from simply creating another account, sometimes indefinitely; however, this particular action is rarely taken, as most Internet Service Providers allocate dynamic IPs to their customers which can change from time to time. These actions are usually invoked for such offenses as violating the website's Terms of Service, trolling, promoting prejudice, disrespect of moderators, or promoting illegal acts.
Gaming usage
The name has been used in more mainstream venues, such as Halo 2 and Halo 3 video game for the Xbox console. Developers Bungie used the term "banhammer" when describing a July 2005 patch that scanned the user's hard drive and summarily restricted him or her from joining Xbox Live without possibility of appeal or leniency if it was determined that his or her copy had been modded. News site Slashdot began using the term at that point and has subsequently applied it to multiple instances of similar housecleaning occurring on World of Warcraft.
In other games such as Blizzard's StarCraft, the host has a hammer icon next to his or her name and is able to boot people from the chat along with the ability to ban people from the channel for a specified time period. The banhammer has even made an appearance in the RPG The Elder Scrolls III: Morrowind, where it can be found on the corpse of an NPC.
Valve CEO Gabe Newell's inventory in Team Fortress 2, when examined using a third-party inspection tool, displays only one item, a Vintage Ban Hammer. While the item's description claims it is merely a joke, the item is listed as equipped, and an in-game model for the weapon exists.
