high costsgovernment A supercomputer is a computer at the frontline of current processing capacity, particularly speed of calculation. http://en.wikipedia.org/wiki/Supercomputer

Computer people refer to these 0s and 1s as bits.Converting data to these 0s and 1s is called digital data representation.

Calculated in B, KB, MB, GB, TB, PB, EB, and other possiblities.

Computers can play multimedia via binary-based code

the main circuit board for a computer. it controls the CPU

CPU is responsible for controlling the speed of the computer and it deals with many processing operations.CPU chips differ in many respects, such as what types of computer the CPU is designed for, its clock speed, and word size

i2 and i4. the higher, the better

refers to chip-based storage. it contains 3 main things

Read only memory. a type of nonvolative memory that stores nonerasable programs.

twp types of Random Acess Memory, which is repsonsible for running programs temporarily

controls programs temporarily

still under development

memory built into the CPU chip to hold data before or during processing.

into which users can insertexpansion cards to give the computer added functionality.

used to add functionality to the computer

electronic path along which bits are transmitted.

moves data between the CPU and RAM

connects the CPU tothe I/O bridge, which connects the CPU and memory to the rest of the bus architecture.

include PCI, PCI Express (PCIe) bus, Universal SerialBus (USB), and FireWire

used to connect peripheral devices to the computers

floating point unitperforms decimal arithmetic

arithmetic/logic unitwhich performs integer arithmetic and logical operations on data

directs the flow of electronictraffic between memory and the ALU/FPU and also between the CPU and inputand output devices.

requests data and instructions before or as they are needed

decodes the instructions input into the CPU,internal cache stores frequently used instructions and data

allows the various parts of the CPU to communicate with each other.

The CPU processes instructions in a sequence called a machine cycle, consisting offour basic steps.

synchronizes all of the computer’s activities.

Scientists work on many new stratigies to develop the computers, such as pipelining, multiprocessing, parallel processing.ways to develop is upgrading internet connection, using seconnd hard drive, etc....

focuses on building computer components at the individual atomic and molecular levels.
