Researchers at the University of California, Berkley, have developed a way to grow nanolasers on a piece of silicon which is believes to pave the way for new generation of laser processors.

In fact the silicon is bad at generating light. Scientists had previously tried to develop chips made of silicon and so-called III-V (three-five) semiconductor materials, but this approach has problems of its own.

Lead researcher and UC Berkeley grad student Roger Chen said in a press release: Growing III-V semiconductor films on silicon is like f ....etc

1.Microprocessors, Microcomputers, andAssembly Language


The microprocessor is a programmable integrated device that has computing and
Decision- making capability similar to that of the central processing unit (CPU) of a computer.
The microprocessor can b embedded in a larger system, can be a stand alone unit controlling processes, or it can function as the CPU of a computer called a microcomputer.
It is difficult for huma ....etc

Pin configuration of 8085 and 8086 Microprocessors


8085 PIN DESCRIPTION
Some important pins are :
• AD0-AD7: Multiplexed Address and data lines.
• A8-A15: Tri-stated higher order address lines.
• ALE: Address latch enable is an output signal. It goes high when operation is started by processor .
• S0,S1: These are the status signals used to indicate type of operation.
• RD¯: Read is active low input signal used to read data from I/O device or ....etc
