Assignment Task:
Instruction: The important process in software development lifecycle. However, a lot of software developer/house tends to ignore the process. Therefore, provide and explain 2 motivations on software design
Then: Two major activities of the software design process include Software Architecture and Detailed Design. Demonstrate on how these two activities being executed? (1) Do you design software when you "write" a program? What makes software design different from coding?
Think about the accompanying punctuation for articulations (where Id is a terminal image addressing an identifier coming about because of lexical examination): Expr ::= 13 | 32 | Id | Expr + Expr | Expr/Expr | Expr ^ Expr | (Expr)
Software Design #1: Costs $902,000, and will facilitate profits of $8,000/year
Give a brief and rudimentary clarification of the standards of how the language coming about because of part may be utilized to make a sentence structure analyser taking a token stream as information and giving as result an theoretical language structure tree relating to part. Notice both transcribed also, consequently created grammar analysers.Y our partner needs to recruit two additional human annotators to re-mark your preparing information. For what reason could this be really smart, how might you measure arrangement in this undertaking.
Also, Summarize any issues connected with left-or right-cooperative administrators in the two methods (in executing the parser and in developing the apparatus) you illustrated to some degree (e). You work at a virtual entertainment organization, and your assignment is to recognize cyberbullying messages in view of the message they contain. You approach an enormous number of messages
(i) What scheduling problem could arise here?
(ii) How could this problem be overcome?
(d) The designer also wishes the real-time system to use demand paged virtual memory for efficiency. What problems could arise here, and how could they be overcome?
6 Numerical Analysis I
(a) For Single Precision in the IEEE binary floating-point standard (IEEE 754) the precision is defined as 24, and the exponent requires 8 bits of storage. With reference to IEEE Single Precision, explain the terms exponent, significand, precision, sign bit, normalised number, denormal number.
(b) Explain the term hidden bit. What are the values of the hidden bit for normalised and denormal numbers? How is the exponent stored and why? How are the exponent, significand and sign bit arranged in memory?
(c) Let x ∗ denote the floating-point representation of a number x. Define the terms absolute error (εx) and relative error (δx) in representing x. How are εx and δx related?
