At present the school has only 3 office computers for Administration work, and 30 computers each in the IT rooms. They have also decided that the entire school should be connected to the internet by making it a HOT SPOT. The school governing body approached a company to provide a quotation showing possible costing. Study the diagram of the Company’s recommendations and help the school to: streamline the features so that they purchase the best setup at the most reasonable price. -—-—-.-.-.. ### Page 3 Le oo Downloaded from hlayiso.com Page 3 of 7 a a « REPEATER IT ROOM LIBRARY ud SERVER <> ITROOM 4 2 dg i<—>} LocaTED 30 PC's 30 PC’s e HERE Ethernet Topology for both IT rooms Fibre opti Will be Ring Topology with CSMA/CD Cables used to connect 10 4S computers, Wireless Access point utd for Internet Lib ~ uses Token Ring QUESTION TWO_ [NETWORK AND COMMUNICATIONS TECHNOLOGIES] Due to the high cost of upgrading for the future, the Principal and the governing body have many questions.

You, as an IT learner, are required to assist in developing software to run the school. 4.1. The Sports department wants your assistance to develop an algorithm that uses the full name (Surname Firstname/s) of a participating athlete, to generate a Registration Number. This number is used to identify the athlete by making tags with the number printed on it. This registration number contains alphanumeric characters. Your task is to examine the already written code and give input by answering the questions: 1. procedure TForm1.Button1Click(Sender: TObject); 2. Var fName, cde : String; 3. len, mid, f,s : integer; 4. begin 5. fName := InputBox('Enter Name','Surname then firstname’,"); 6. len := Length(fName); 7. mid := len div 2; 8. if odd(len) then 9. begin 10. mid := mid + 4; 11. cde := copy(fName,1,1) + copy(fName,mid,1) + copy(fName,len-2); 12. end 13. else 14. cde := copy(fName,mid,1) + copy(fName,mid+1,1) + copy(fName,len-1); 15. f:=len div 10; 16. s:=len mod 10; 17. cde := IntToStr(f) + cde + IntToStr(s); 18, RichEdit1.Lines.Add(cde); 19. end; 4.1.1. Trace the code to determine the registration number formed when the input is: (N.B. No trace table is required as marks will only be awarded for output) a) Jonathan Francis (2) b) Hlakanipho Duma (2) c) Tony Cho (2) 4.1.2. Describe in not more than SEVEN steps exactly what is being done with the input to obtain the desired registration code. (7) 4.1.3, You need to modify the program so that it removes spaces found in the reg no. formed. Write the Delphi statements to solve this problem. At which line would you insert the new statements. (6) ### Page 6 Downloaded from hlayiso.com: age 6 of 4.2. The Library needs to create a database in order to store the details of all members. Software developers have agreed on the details necessary to construct the respective record. Your task is to continue with the completion of the a software as specified by the questions that may follow: THE RECORD STRUCTURE Here is a list of fields that constitutes the record. The record represents the details of all library members. . 1. A Boolean variable (Learner) to represent whether a member is a learner or not. If not a learner, the member could be an educator or any other staff member in the school. 2. A string variable called RegNo that will store a code generated by the members full name. 3. A real variable called fines, that stores the total fines, if any, owed by the member. 4, A String variable, fName, that stores the full name of the member. 4.2.1, Declare the object type for the class variables above. To do this you must only write’ the segment of the code that defines the instance variables. The name of the object type is LibMem. : : (3) ( ) 4.3. Study the class diagram which represents the object class for the record structure above and answer the questions based on it.

Clearly distinguish between a class and an object. ‘ (2) 4.3.2. The class diagram has various methods. Identify the three different types of methods from the class and give an example of each from the diagram. (6) 4.3.3, From the class diagram identify the following: ~~ =~ ay The parametrised constructor, = eg b) A Mutator method (1) c) An Accessor method (1) ### Page 7 Downloaded from hlayiso.com Page 7 of 7 4.4, Discuss the prupose of accessors and mutators. (2) 4.5. How do procedures differ from functions? (2) 4.6, List the two auxillary methods methods from the class diagram. {2) 4.7. You need to redefine the auxillary method below : calcAmtOwing(amnt : real; days: integer; charge:real); So that the value of amnt changes in the calling statement of the method. (1) e 4.7.1, What kind of parameter have you transformed amt into in 4.7.? (1) 4.7.2. What is the name given to the parameters found in the: a) Method calling statement e.g. calcAmtOwing(a,d,c); (1) b) Method definition e.g. calcAmtOwing(Var amnt : real; days: integer; charge:real); (1) [43] FINAL TOTAL : 90 +3 x 2 = 60 ### Page 8 Downloaded from hlayiso.com ### Page 9 Downloaded from hlayiso.com “Seo|nap a], gow Wosy a|qyssod UOISIAE|} CE pue BUuj2UE/9JL09 OApIA ‘AL aljqow Us joD0}03d joqUOD JaysUeL “Eye jooojoud sasueN apis “Zy'S Jos0}0zd Jaysued xeyedAH ‘Ty's “Jouueyp uoReoIUNWUIOD e Jo Aysedeo Suyjpuey exep je03 Oy 0} s1BJa2 YIPIMpUR “YEE aremayos Suisnuenpe $i ae¢py “ECE “OIL B42 JO Jepuas By3 02 YOeq pus pue ,sIBSN Jo sjleJep pu sqUaA@ P10da/ 0} 2)Gz SI Jey? ‘Dy JO ysOMYaU e JO Eale a|qea}epuN Ue LI Pagpo} sj Jeu} aseMYJOS “Z"E"E Lua YUN! paUurjosun Tes ae auemids nuy ‘wedsnuy ‘ snuianuy ‘Z°€ ~s1ayjo arepiuiul Jo yoaads azey a,owosd 02 21 asn Aew ajdoag - om JueVOdUI pue sarINp Wey} 399/Fou pue y UO sun dow! puads 03 pual jim ajdoed — "T's BBYHL NOSSO “Aldi pue djo, ‘Sulpueqpeoig ajged oj aaewaye Ssaja4IM ‘AIANIBULOD PuegpeOIg aI!Gow SapIAosd pue 141 UL? ase JOpIM & $39A03 Y ~sp}e1 Jaysuen eep sey WO. apaoud AjUOWLUOD UD Yr14M PJEPUETS SUOEIIUNWWOD ssafaM & S!— XVIALM (2 UDP YSIy ‘soo1aras Sues ‘AuoYdaay g] Saye YyYpimpueg paads ysiy siys “sse2se JouSqW! pueg-peosg eQIN YM Sizsn @PIAOIE 31 “DE SMOHOS 2eYI PJepURyS SUOHeOIUNWWOD SsUOY alIqow Jo LOHeJEUaT YLNOY BUI SI OF (G “SUdd psoueyUz se UMoUy Osly¥ “ADojouUde} oIpes N¢E-aud @ polepisuod S| FOS "WSO 40 usIsUS}xe o1qneduloo-premnjoRg B Se Soyer UOISSIWUSUBI} EJP perosdu! sMO|TE yeuR ABojoUYoS} suoYd Syqow jeubip e si ~ UOAN|OAT NGS 10} sexe Byeg psoueYUS (e ‘OTT -Asng se uay03 243 SeW pue UaYO} BY} OF peppe ue sassauppe Janlades pue JApUAs ‘elep Sppe Ud}O} Sy?
