Propositional truth tables:
There {X\t} is a substitution that replaces all occurances of variable X with a term representing an object t as:
By repeating this for all the quantifiers than we get a set of ground formulae in which we have to check that if the original sentence is true or false. But unfortunately, we don't have specified there that our domain Δ is finite - like in example we see that it may contain the natural numbers - but there may be a infinite number of sentences to check for a given model! So there may be also be an infinite number of models. And although we have a proper definition of model hence a proper semantics for first-order logic and we can't rely on having a finite number of models like we did where drawing propositional truth tables.
Describe the concept of pipelining. Ans: Pipelining is the means of executing machine instructions concurrently. This is the effective way of organizing concurrent activity in
There are various approaches to the classification of Computer Networks. One such classification is based on distance approach. Networks can be classified into LAN, WAN and MAN net
Explain at least one modulation technique used for high speed modems. FSK - Frequency Shift Keying: In such technique the frequency of the carrier signal is changed as per to
Explain FIFO Page replacement algorithm. FIFO policy: This policy only removes pages in the order they entered in the main memory. By using this policy we simply eliminate a
The NAND gate. The NAND gate is equivalent to an AND gate followed by a NOT gate so that the output is 0 when all of the inputs are high, otherwise the output is 1. There may
