Across: 1 - The system bus can be lopically divided into a data bus, address bus. control bus and bus. 2 - In interrupt handling this is the process of copying CPU register CPU register values to the top of a stack. 4 - Magnetic is the tendency of magnetically charged particles to lose their charge over time. 7 - There are 2 basic RAM types: SRAM and DRAM. The "D" in DRAM stands for? 8- A reserved area of primary storage accessed on a last-in, first-out (LIFO) basis; this mechanism enables a program suspended by an interrupt to resume execution in exactly the same state as before an interruption. 10 - A processor that regulates the physical actions of storage and I/O devices; connects these devices to the system bus or a subsidiary bus. 12 - One bus protocol approach to avoid collisions is a_ -_- bus, in which any device can assume control of the bus or act as bus master for transfers to any other device. 15 - A small reserved area of main memory (usually DRAM or SRAM) that holds data in transit from one device to another and is used to resolve differences in data transfer unit size. 16 - A compact disc bit values are represented as flat areas called lands and concave dents called on a reflective layer. 17 - The capacity to accept and hold a magnetic charge Down: interrupt handling this is the process of removing register values from the top of stack and loading them back into the correct CPU registers. 3 - There are 2 basic RAM types: SRAM and DRAM. The "S" In SRAM stands for? 5 - A storage device that mimics the behavior of a magnetic disk drive but uses flash RAM or other NVM (nonvolatile memory) devices as the storage medium and read/write mechanism. 6 - A signal sent to the CPU over the control bus that some event requires it to execute a specific program or process; used to prevent inefficiency caused by I/O wait states. 8 - The bus is an internal communication channel connecting all hardware devices, including the CPU, memory, storage and i/o devices. 9 - A cache controller guesses what data will be requested in the near future and loads this data from the storage device to cache before it is actually requested. Guessing methods can be simple or complex. When a read operation accesses data contained in cache (put there through the guess), it is called a cache_ 11 - Multicore and multi-processor architectures are examples of scaling which is a term to describe approaches to increasing processing and other computer system power by using larger and more powerful computers. 13 - DRAM uses a _ _cycle, because the capacitors lose electrical charge quickly and require a new infusion of power thousands of times per second. Across: Down: 19 - Characteristics which can vary among storage devices include: speed, volatility, 14 - Multi- architecture is a more access method, portability, traditional approach to multiprocessing that and uses two or more capability. s on a single motherboard or set of interconnected 21 - A cache controller guesses what data will motherboards; slower than multicore be requested in the near future and loads this architecture. data from the storage device to cache before 16 - _access is an access method it is actually requested. Guessing methods that can access multiple storage locations can be simple or complex. When the data in a simultaneously; can also be achieved by read operation is not in the cache (put there subdividing data items and storing the through the guess), it is called a cache component pieces on multiple storage 22 - Three access methods for storage devices devices. include: random and parallel. 18 - There are 4 subsidiary busses: memory, 24 - A device attached to a bus that can storage and external 1/0. initiate a data transfer operation or send a 20 - Magnetic is the reduction in command to another device; it controls all strength of a stored magnetic charge because access to the bus. of interference from adjacent magnetic charges of opposite polarity. 26 - An area of high-speed memory (usually RAM) for storage device accesses that 23 - Clusters and grids are examples of scaling improves the performance of read and write which is a term to describe operations. Characteristics are: Used for partitioning processing and other tasks bidirectional data transfer, used only on among multiple computer systems. storage devices accesses and data content is 25 - Magnetic disk media are flat, circular not automatically removed as it is used. platters with metallic coatings that are 27 - A microprocessor architecture that rotated beneath read/write heads. A embeds multiple CPUs and cache memory on one concentric circle of a platter, or the a single chip. surface area that passes under a read/write head when its position is fixed
