Sample Paper Computer and Information Technology(CSIT113) BCA 1st Sem. [Max Marks: 70] Note: Attempt Questions from all sections as directed. Section A - Attempt any Two questions out of Four. Each question carries 7.50 marks. [15 Marks] Question No: 1 Explain the different types of memory with example. Question No: 2 Define operating system and various OS services in detail. Question No: 3 Evaluate 11001 – 11100 with 2’s compliment and convert 63.48 to decimal number. Question No: 4 What is the difference between Flowchart and algorithm? Explain the advantages and disadvantages of flowchart. Section B - Compulsory Questions. Each question carries 7.50 marks. [15 Marks] A waiter takes an order at a table, and then enters it online via one of the six terminals located in the restaurant dining room. The order is routed to a printer in the appropriate preparation area: the cold item printer if it is a salad, the hot-item printer if it is a hot sandwich or the bar printer if it is a drink. A customer’s meal check-listing (bill) the items ordered and the respective prices are automatically generated. This ordering system eliminates the old three-carbon-copy guest check system as well as any problems caused by a waiter’s handwriting. When the kitchen runs out of a food item, the cooks send out an ‘out of stock’ message, which will be displayed on the dining room terminals when waiters try to order that item. This gives the waiters faster feedback, enabling them to give better service to the customers. Other system features aid management in the planning and control of their restaurant business. The system provides up-to-the-minute information on the food items ordered and breaks out percentages showing sales of each item versus total sales. This helps management plan menus according to customers’ tastes. The system also compares the weekly sales totals versus food costs, allowing planning for tighter cost controls. In addition, whenever an order is voided, the reasons for the void are keyed in. This may help later in management decisions, especially if the voids consistently related to food or service. Acceptance of the system by the users is exceptionally high since the waiters and waitresses were involved in the selection and design process. All potential users were asked to give their impressions and ideas about the various systems available before one was chosen. Question No: 1 Discuss the information system and various levels of IS in detail. Question No: 2 Explain how information has been stored in the system and accessed at various stages.
