Q. Define about Hyper-threading technology?
Hyper-threading technology enables a single microprocessor to behave as two separate threaded processors to operating system and application program which use it.
Hyper-threading requires software that has multiple threads and optimizes speed of execution. A threaded program executes rapidly on hyper threaded machine. Though it must be noted that not every program can be threaded.
The other architecture that has gained popularity over last decade is power PC family. These machines are called as Reduced set instruction computer (RISC) based technologies. RISC technologies are finding their application because of simplicity of Instructions. The IBM made an alliance with Apple and Motorola who has used Motorola 68000 chips in their Macintosh computer to make POWER PC architecture. A number of the processors in this family are:
