The IBM 305 RAMAC, publicly announced on September 13, 1956, was the first commercial computer that used a moving head hard disk drive magnetic disk storage for secondary storage. RAMAC stood for 'Random Access Method of Accounting and Control'. Its design was motivated by the need for real time accounting in business. The first RAMAC to be used in the US auto industry was installed at Chrysler's MOPAR Division in 1957. It replaced a huge tub file which was part of MOPAR's parts inventory control and order processing system. The 305 was one of the last vacuum tube computers that IBM built. The IBM 350 disk system stored 5 million 8-bit 7-bits plus 1 odd parity bit characters. It had fifty 24-inch diameter disks. Two independent access arms moved up and down to select a disk, and in and out to select a recording track, all under servo control. Average time to locate a single record was 600 milliseconds. Several improved models were added in the 1950s. The IBM RAMAC 305 system with 350 disk storage leased for $3,200 per month in 1957 dollars, equivalent to a purchase price of about $160,000. More than 1000 systems were built.…

Drum memory is a magnetic data storage device and was an early form of computer memory widely used in the 1950s and into the 1960s, invented by Gustav Tauschek in 1932 in Austria. For many machines, a drum formed the main working memory of the machine, with data and programs being loaded on to or off the drum using media such as paper tape or punched cards. Drums were so commonly used for the main working memory that these computers were often referred to as drum machines. Drums were later replaced as the main working memory by memory such as core memory and a variety of other systems which were faster as they had no moving parts, and which lasted until semiconductor memory entered the scene.…

A memory-mapped file is a segment of virtual memory which has been assigned a direct byte-for-byte correlation with some portion of a file or file-like resource. This resource is typically a file that is physically present on-disk, but can also be a device, shared memory object, or other resource that the operating system can reference through a file descriptor. Once present, this correlation between the file and the memory space permits applications to treat the mapped portion as if it were primary memory. The primary benefit of memory mapping a file is increasing I/O performance, especially when used on small files. Accessing memory mapped files is faster than using direct read and write operations for two reasons. Firstly, a system call is orders of magnitude slower than a simple change to a program's local memory. Secondly, in most operating systems the memory region mapped actually is the kernel's page cache, meaning that no copies need to be created in user space.…

A live CD, liveDVD, or live disc is a CD or DVD containing a bootable computeroperating system. Live CDs are unique in that they have the ability torun a complete, modern operating system on a computer lacking mutablesecondary storage, such as a hard disk drive. Live USB flash drives aresimilar to live CDs, but often have the added functionality ofautomatically and transparently writing changes back to their bootablemedium.…

Brk and sbrk werememory management subroutines/system calls in older versions of the Unixoperating system. They operate at a lower level than the standard mallocfamily of memory management routines, by changing data segment spaceallocation. The brk and sbrk subroutines dynamically change the amountof space allocated for the data segment of the calling process. (Forinformation about segments, see the exec subroutine. For informationabout the maximum amount of space that can be allocated, see the ulimitand getrlimit subroutines.) The change is made by resetting the breakvalue of the process, which determines the maximum space that can beallocated. The break value is the address of the first location beyondthe current end of the data region. The amount of available spaceincreases as the break value increases. The available space isinitialized to a value of 0 at the time it is used. The break value canbe automatically rounded up to a size appropriate for the memorymanagement architecture.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - High Quality Content by WIKIPEDIA articles! Replication is the process of sharing information so as to ensure consistency between redundant resources, such as software or hardware components, to improve reliability, fault-tolerance, or accessibility. It could be data replication if the same data is stored on multiple storage devices, or computation replication if the same computing task is executed many times. A computational task is typically replicated in space, executed on separate devices, or it could be replicated in time, if it is executed repeatedly on a single device. The access to a replicated entity is typically uniform with access to a single, non-replicated entity. The replication itself should be transparent to an external user. Also, in a failure scenario, a failover of replicas is hidden as much as possible.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.Virtual memory is a computer system technique which gives an application program the impression that it has contiguous working memory, while in fact it may be physically fragmented and may even overflow on to disk storage. Systems that use this technique make programming of large applications easier and use real physical memory more efficiently than those without virtual memory. Virtual memory differs significantly from memory virtualization in that virtual memory allows resources to be virtualized as memory for a specific system, as opposed to a large pool of memory being virtualized as smaller pools for many different systems.…

In computing, symmetric multiprocessing or SMP involves a multiprocessor computer architecture where two or more identical processors can connect to a single shared main memory. Most common multiprocessor systems today use an SMP architecture. In the case of multi-core processors, the SMP architecture applies to the cores, treating them as separate processors. SMP systems allow any processor to work on any task no matter where the data for that task are located in memory; with proper operating system support, SMP systems can easily move tasks between processors to balance the workload efficiently.…

Error-correcting code memory is a type of computer data storage that can detect and correct the more common kinds of internal data corruption. ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing and as servers. ECC memory maintains a memory system effectively free from single-bit errors: the data read from each word is always the same as the data that had been written to it, even if a single bit actually stored, or more in some cases, has been flipped to the wrong state. Some non-ECC memory with parity support allows errors to be detected, but not corrected; otherwise errors that may occur are not detected.…

In computing andtelecommunications, a unit of information is the capacity of somestandard data storage system or communication channel, used to measurethe capacities of other systems and channels. In information theoryunits of information are also used to measure the information contentsor entropy of random variables.The most common units are the bit, whichis the capacity of a system that can be in only two states, and the byteor octet which is equivalent to eight bits. Multiples of these units canbe formed from these with the SI prefixes (power-of-ten prefixes) or thenewer IEC binary prefixes (binary power prefixes). Information capacityis a dimensionless quantity, because it refers to a count of binarysymbols.…
