Q. Explain about Cathode Ray Tubes?
Cathode ray tube is the major technology on that televisions and monitors have been based. CRT is a partially evacuated glass tube which is filled with inert gas at low pressure. A specially designed Cathode (negatively charged electrode) shoots beams of electrons at high speed in the direction of an anode (positively charged electrode) which imposes on screen that is coated with small phosphor coated dots of the three primary colours. This cathode is also known as an Electron Gun. Actually there can be three separate guns for three colours (Red, Green and Blue) or one gun for all three.
Describe queue? Ans: It is a type of data structure in which the data are stored in and retrieved on a First in first out (FIFO) basis. It grows in the direction of increasin
Unification - Artificial intelligence: We have said that the laws of inference for propositional logic detailed in the previous lecture can also be used in first-order logic.
Arterial puncture - Specimen collection: Arterial puncture: this requires special skill and usually performed only by physician. The preferred site is radial arter
Associativity of Connectives : Here brackets are very important in order to tell us where to perform calculations in arithmetic and logic. By using these brackets we evaluate
Define underflow and overflow. Underflow: If the result the arithmetic operation including n-bit numbers is too small to show by n-bits, underflow is said to occur. Overflow
A device that forwards data packet from one network to another is known as a Switch device.
How many address bits are required to represent 4K memory ? Ans. 12 address bits are required for representing 4K memory, as 4K = 2 2 x 2 10 = 2 12 Therefore 1K = 1024
RAW and WAW - Data hazards: RAW (read after write) - j tries to read a source before i writes it, hence j wrongly gets the old value .This is the most usual type of
We have determined the general architecture and register set of MIPS microprocessor. Our subsequent task is to look at functionality of ALU, the CU and how an instruction is execut
The output of SR flip flop when S=1, R=0 is ? Ans. When for the SR flip-flop S=set i/p R=reset i/p, as S=1, R=0, Flip-flop will be set means output will be one.
