Q. Explain Error Detection and Correction Codes?
Before we wind up data representation in reference of today's computers one should determine about code that helps in correction and recognition of errors. Computer is an electronic media hence there is a probability of errors at the time of data transmission. These kinds of errors can result from disturbances in transmission media or external environment. But what is an error in binary bit? An error bit alters from 0 to 1 or 1 to 0. One of simplest error detection codes is known as parity bit.
What is virtual memory? Method that automatically move program and datablocks into the physical main memory when they are needed for execution are known as virtual memory.
What are condition codes? In many processors, the condition code flags are kept in the processor status register. They are either set are cleared by lots of instructions, so th
Q. Explain about integrated circuit? An integrated circuit is created on a thin wafer of silicon that is splitted into a matrix of small areas (size of the order of a few m.m.

The 68HC11 series is based on the Motorola 6800/1 programming instruction set and hence is a fairly simple 8 bit microprocessor. The internal structure of the 6800/1 is shown below
Define bidirectional bus? A bidirectional bus is that which permits the transfer of data either from memory to CPU during a read operation or from CPU to memory during write op
