If one developer writes code for the client program and another developer writes code for the server program, and both developers carefully follow the rules of the RFC, then the two programs will be able to interoperate. The lasting romance remains, alas, just a dream. His latest obsession is a toasted sandwich-maker called SN0008011555811. In order to win her affections he plans to buy her a chocolate muffin from her favourite shopFat Finbar's World of Cakebefore stealing a bunch of flowers from the local cemetery, giftwrapping the presents, and presenting both gifts to her. They are covered in more detail in Chapter 5.) We introduce UDP and TCP socket programming by way of a simple UDP application and a simple TCP application. We present the simple UDP and TCP applications in Python. We could have written the code in Java, C, or C++, but we chose Python mostly because Python clearly exposes the key socket concepts. The central behaviour of programs in a programming language can be defined in terms of a formal logical system, in which each sentence . Start with 3 goats in your trip (use a constant for this). Assume a processor has two symmetric groups that contain both utilitarian units and an issue cradle. In this processor, directions should be controlled to a specific, Have your loop conduct at least 10 goatdates (use a constant for this). "Possibly you settle your assessments, or you will be placed in prison." "I cover my charges, so then, at that point, I can't be placed in prison." (be certain that both the subject and predicate are plainly stated as classes of things) (a) If Reach is NP-finished then P=NP. (b) If Reach is NP-finished then NP6=PSPACE.If Sat is PSPACE-finished then NP=PSPACE. [3 marks]. For every one of the accompanying matches, state whether they are semantically same; on the off chance that not, express a nontrivial condition on the subexpressions e,e1, e2, e3 that makes them in this way, and make sense of casually why it suces. (c) l := 3;e Put every one of the accompanying assertions into standard structure as all out recommendations and distinguish them as A, E, I or Opropositional structures. In view of the propositional structure given, decide the [indicated proposition] and decide if it is comparable to the first.

In schema normalisation, is Boyce-Codd Normal Form (BCNF) always to be preferred over 3rd Normal Form (4NF)? Explain your answer.

[4 marks] (b) Describe an algorithm (other than thresholding) which will convert a greyscale image (8 bits per pixel) to a bi-level black and white image (1 bit per pixel), with the same number of pixels, while retaining as much detail as possible. [8 marks] (c) Explain what specular and diffuse reflection are in the real world. State and explain equations for calculating approximations to both in a computer.

[2 marks] (b) Java is sometimes said to be "dynamically typed" in that a variable whose type is (class) C can be assigned a value of (class) D provided that D extends C; conversely a variable of type D can be assigned a value of type C using a cast. By considering storage layouts, explain why the former assignment is always valid and the latter sometimes invalid. [4 marks] (c) A new programming language has the notion of "statically scoped exceptions" in which the program exception foo; void f() { try { void g() { raise foo; } try { g(); } except (foo) { C2 } } except (foo) { C1 } } would execute C1 rather than C2 as the former was in scope at the raise point. By analogy with statically scoped variables, or otherwise, explain how such exceptions might be implemented on a stack. [10 marks] 6 CST.2004.13.7 7 Artificial Intelligence In the following, N is a feedforward neural network architecture taking a vector of n inputs. Consider different versions of an optimising compiler, each of which uses IEEE standard representation for all variables. Give two reasons why they might compile a floating-point program into code that, when run, produces differing results. [2 marks] 6 CST.2016.1.7 6 Numerical Methods A picnicker brings hot black coffee and cold milk in two identical insulated flasks and then mixes them for his drink. His friend claims that the drink would have ended up the same temperature if he had mixed the two at home and brought one flask. Note: The temperature of an object is the heat energy within it divided by its heat capacity. The rate of heat energy flow from a hotter to a cooler object is their temperature difference divided by their insulation resistance. When two fluids are mixed the resultant temperature is the sum of their initial temperatures weighted by their proportions. (a) Give a suitable state vector for a simple, finite-difference, time domain simulation of the drink system. [3 marks] (b) List the initial values and any other parameters that are needed for the simulation.

CST.2004.7.4 8 With Python there are fewer lines of code, and each line can be explained to the novice programmer without difficulty. But there's no need to be frightened if you are not familiar with Python. Describe two quantitative and two qualitative techniques for analysing the usability of a software product.

Suppose R is a rule that integrates constants exactly over [1, 1], and that f(x) is bounded and Riemann-integrable over [a, b].
