    en.wikipedia.org/wiki/Rama

    Balak Ram, the 5-year-old form of Rama, is the principal deity of the Ram Mandir in Ram Janmabhoomi The ancient epic Ramayana states in the Balakanda that Rama and his brothers were born to Kaushalya and Dasharatha in Ayodhya , a city on the banks of Sarayu River .

  3. Real RAM - Wikipedia

    en.wikipedia.org/wiki/Real_RAM

    The "RAM" part of the real RAM model name stands for "random-access machine". This is a model of computing that resembles a simplified version of a standard computer architecture. It consists of a stored program, a computer memory unit consisting of an array of cells, and a central processing unit with a bounded number of registers. Each memory ...

    en.wikipedia.org/wiki/Computer_hardware

    Computer architecture requires prioritizing between different goals, such as cost, speed, availability, and energy efficiency. The designer must have a good grasp of the hardware requirements and many different aspects of computing, from compilers to integrated circuit design. [ 14 ]

  5. Memory management unit - Wikipedia

    en.wikipedia.org/wiki/Memory_management_unit

    A 68451 MMU, which could be used with the Motorola 68010. A memory management unit (MMU), sometimes called paged memory management unit (PMMU), [1] is a computer hardware unit that examines all memory references on the memory bus, translating these requests, known as virtual memory addresses, into physical addresses in main memory.

  6. Computer memory - Wikipedia

    en.wikipedia.org/wiki/Computer_memory

    The operating system will place actively used data in RAM, which is much faster than hard disks. When the amount of RAM is not sufficient to run all the current programs, it can result in a situation where the computer spends more time moving data from RAM to disk and back than it does accomplishing tasks; this is known as thrashing.

  7. Synchronous dynamic random-access memory - Wikipedia

    en.wikipedia.org/wiki/Synchronous_dynamic_random...

    DDR SDRAM employs prefetch architecture to allow quick and easy access to multiple data words located on a common physical row in the memory. The prefetch architecture takes advantage of the specific characteristics of memory accesses to DRAM. Typical DRAM memory operations involve three phases: bitline precharge, row access, column access. Row ...

  8. Computer architecture - Wikipedia

    en.wikipedia.org/wiki/Computer_architecture

    The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.

  9. 128-bit computing - Wikipedia

    en.wikipedia.org/wiki/128-bit_computing

    IPv6 routes computer network traffic amongst a 128-bit range of addresses. ZFS is a 128-bit file system. 128 bits is a common key size for symmetric ciphers and a common block size for block ciphers in cryptography. The IBM i Machine Interface defines all pointers as 128-bit. The Machine Interface instructions are translated to the hardware's ...
