Give difference between top down parsing and bottom up parsing.
Top down parsing: Specified an input string, top down parsing tries to derive a string identical to this by successive application of grammar rules to the grammar's distinguished symbol. While such a string is acquired, a tree showing its derivation would be the syntax tree for an input string. Therefore if ? is input-string, a top-down parse finds a derivation sequence.
Bottom up parsing: This parse attempts to increase syntax tree for an input string by a sequence of reduction. If the input string can be decreased to the distinguished symbol, the string is valid. If string is not valid, error would be noticed and indicated during the process of reduction itself.

I think yes...so if 8259 gives interrupt then it will be serviced instantly but since into pin is left hanging the insr bit will never be set...and so whenever any interrupt occurs
Read in integers until a zero is read in. Keep a total of both the quantity and the sum of the negative integers and the positive integers. Once a zero is read in (signifying the
Clocked SR flip flop A clock pulse is a sequence of logic 0, logic 1, and logic 0 occuring on the CLK input. Time t n occurs before the clock pulse and time t n+1
Consider a collection class that is similar to the ArrayList class, except that elements are sorted in a certain order. We will call this class SortedArrayList. This c
How does CPU know that an interrupt has taken place? There needs to be a line or a register or status word in CPU which can be increased on occurrence of interrupt situation.
