Answer: In fact, the say block itself is like an algorithm, where we provided an input of hello, world and it produced the output of Scratch (the cat) saying that phrase: The ask block, too, takes in an input (the question we want to ask), and produces the output of the answer block: We can then use the answer block along with our own text, hello, , as two inputs to the join algorithm . UNIT IVComputer Arithmetic: Introduction, Addition and Subtraction, Multiplication Algorithms, DivisionAlgorithms, Floating point Arithmetic operations.Input-Output Organization: Peripheral Devices, Input-Output Interface, Asynchronous data transfer,Modes of Transfer, Priority Interrupt, Direct memory Access, Input Output Processor (IOP),Intel 8089IOP. For example, we know the following represents one hundred and twenty-three. We can also drag in the ask and wait block, with a question like Whats your name?, and combine it with a say block for the answer: But we didnt wait after we said Hello with the first block, so we can use the say () for () seconds block: We can use the join block to combine two phrases so Scratch can say hello, David: Notice that we can nest instructions and variables. x[Ms8{=X$p2[&Ta3/@XrvclS9%!=~jl -(.

Modern electronic components have long lives. What a computer system architecture entails is the design of the computer system and how it functions with the various categories that are microarchitecture, instruction set architecture and system design, all these categories are what constitute the basic CPUs architecture, and it is the key in the function of the computer as a whole. Now that we know the characteristics of computers, we can see the advantages that computers offer. Sorry, preview is currently unavailable.
