Information Procesing Cycle (IPC) typically involves four main stage: i\. \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ ii\. \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ iii\. \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ iv\. \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ 2\. Draw a diagram for information processing cycle. -- -- **[Section B (PSPM)]** 1\. Analyse the use of IPC based on the given scenarios. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Jane logs into the ticket website. She selects "Despicable Me 4" for August 22 at 7.00 PM and buy 2 tickets. The system confirms seatare available. She pays RM 32.00 with her credit card. The system shows her digital tickets for seats A11 and A12 and sends a confirmation email. The transaction details are saved and backed up. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- **Stage** **Activities** ----------- ---------------- Input Process Output Storage 2. **[Number System and Representation]** **PSPM** 1. Convert the following storge capacity into its appropriate units. a. 8192 Bits = \_\_\_\_\_\_\_\_\_\_\_\_\_\_ Byte b. 1 Megabyte = \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ Bits c. 3 Gigabyte (GB) = \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ Kilobyte (KB) d. 1024 Kilobyte (KB) = \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ Bits 2. Convert between a. Binary and Hexadecimal i. 111011101010101~2~ ii. 011111101~2~ iii. 11110110~2~ b. Hexadecimal and decimal i. F1FA~16~ ii. 11A~16~ iii. 8CB~16~ 3. Box A consists of 11110~2~ pencils and Box B consists of few pencils. The total pencils for both box is 140~10~. Calculate how many pencils are there in Box B. Give your answers in binary form. 3. **[Information Coding Scheme]** 1\. Based on the given words determine bits and bytes using ASCII, EBCDIC and Unicode coding scheme. *Kolej Matrikulasi Kedah* **Coding Scheme** **ASCII** **EBCDIC** **Unicode** -------------------------- ----------- ------------ ------------- **Total number of bits** **Total number of byte** 4. **[Logic Gate and Simple Logic Circuit]** 1\. Identify **three (3)** basic logical operators i\. \_\_\_\_\_\_\_\_\_\_\_\_\_ ii\. \_\_\_\_\_\_\_\_\_\_\_\_ iii\. \_\_\_\_\_\_\_\_\_\_\_\_ 2\.
