Details are provided and csv file uploaded below; - Refer to the documents in the dataset area in Brightspace for the list of dataset columns to use, note that all listed columns need to be used, and need to be present within your source code to verify you are using the dataset provided. The first record in the data set may contain the column names, if so you may skip over this record when reading in and parsing the data set data. You may use your previous work in this course as a reference / starting-point but I expect modifications, i.e. passing in older work again with none to very small changes will not earn marks. Tasks - a project, in your language of study that meets the following requirements: a record object (also known as entity object, data-transfer object) that uses the column names from the dataset as part of the source code, e.g. variable names, accessors/mutators names, or constants. Use File-IO on startup to open and read the dataset, initializing a few record objects with data parsed from the first few records in the csv file. The record objects should be stored in a simple data structure (array or a list), use exception handling in case the file is missing or not available. Loop over the data structure, and output the record data on screen. TLBs and caches are examples of content-addressable memories (CAMs). (a) What is the principal difference between a CAM and a RAM? [4 marks] (b) What is the difference between fully associative, set associative and direct mapped lookup? [6 marks] (c) Why are TLBs always much smaller than caches?

For each of(a) Describe how the Lempel Ziv text compression algorithm works, illustrating your answer by deriving the sequence of numbers and corresponding bit patterns it would generate when applied to a string starting with the following 24 characters: ABCDABCDABCDABCDABCDABCD ... You may assume that the initial table is of size 256 (containing bytes 0 to 2255) and that Computer Graphics and Image Processing Given a sequence of points (Vi) n i=0 on a plane, consider the problem of interpolating a smooth curve through all of the points in order by constructing a sequence of polynomial parametric functions, one for each interval [Vi , Vi+1] n21 i2=0 . (a) What is meant by Ck continuity at the junction between two curve segments? (b) Explain how the degree of the polynomial function for a curve segment constrains the continuity at its two ends. What continuity can be achieved at each end of a cubic segment Given m ' 0 , Modern work area and server processors support concurrent multithreading (additionally called hyperthreading). At the point when will there be an exhibition benefit inhow many significant decimal digits of w can be relied on? [3 marks] on of a Turing machine that is specified by a quintuplet description. [4 marks] (c) Define the configuration of a Turing machine at step t, and establish equations that specify the configuration of a k-symbol Turing machine at step (t + 212) in terms of the configuration at the previous step t. [6 marks] (d) Explain how you would use your equations to simulate a specific Turing machine by a register machine whose program encodes the quintuplet description. for disseminating this data across the organization. It would be ideal for you to determine the configuration of your messages and the size of any message fields This question connects with double requirement fulfillment issues (CS2Ps). A CSP has a set. It will contain the precomputed values for this inquiry. InTo what extent does this support Turing's Thesis? [Explicit program for a register machine is not required.] [8 marks] 8 Computer Graphics and Image Processing Describe an algorithm for performing scan conversion of a set of 3D polygons, including details of clipping, projection, and the underlying 2D polygon scan conversion algorithm. You may assume that you are given the colour of each polygon and that no lighting calculations are required. Please state any additional assumptions that you need to make. Ray tracing is not an acceptable answer to this question.

[5 marks] (c) Consider the standard POSIX file-system access control mechanism: (i) Under which conditions can files and subdirectories be removed from a parent directory? [2 marks] (ii) Many Unix variants implement an extension known as the "sticky bit". What is its function?
