Hey It'z — ready when you are. Here are the answers to your Computer Studies questions: 8. a) The formula D10E12 was initially stored in cell F10. When copied from F10 to M20: Column shift: F to M is 7 columns to the right. Row shift: 10 to 20 is 10 rows down. Applying this shift to D10: Column D + 7 columns = K Row 10 + 10 rows = 20 So, D10 becomes K20. Applying this shift to E12: Column E + 7 columns = L Row 12 + 10 rows = 22 So, E12 becomes L22. The formula in cell M20 will be: =K20*L22 b)* To display the positive adjusted marks for mathematics using the value in cell B6 (which is "FACTOR" and appears to be 20% or 0.2), and assuming the mathematics mark for the first student is in B2, the formula in cell E2 should reference B2 relatively and B6 absolutely. The adjustment is likely Mark (1 + Factor). Mathematics mark for the first student is in B2. The factor is in B6, which should remain constant when copied, so it needs absolute referencing (B6). The formula in cell E2 would be: =B2*(1+\B\6) 9. a)* The operating system handles errors in a computer by: Detecting and reporting errors*: It identifies hardware or software malfunctions and notifies the user or logs the event. Attempting recovery*: It may try to resolve the error, for example, by closing a non-responsive program or restarting a faulty driver, to prevent system crashes. 10. a)* A candidate key* is any attribute or set of attributes that can uniquely identify a record in a table. A table can have multiple candidate keys. A primary key* is a candidate key that is specifically chosen by the database designer to uniquely identify each record in a table. A table can only have one primary key. b)* Two functions of a query are: To retrieve specific data* from one or more tables based on defined criteria. To perform calculations* on data, such as summing values, counting records, or finding averages. 12. The function of cache memory is to store frequently accessed data and instructions from the main memory (RAM) in a small, very fast memory. This reduces the time the CPU spends waiting for data, thereby speeding up data retrieval and improving overall system performance. 13. A selection control structure (IF-THEN-ELSE) allows a program to execute different blocks of code based on whether a condition is true or false. Here is a description of a flowchart for a selection control structure: Start/End Symbol (Oval): Marks the beginning of the process. Flow Line (Arrow): Connects the Start symbol to the Decision symbol. Decision Symbol (Diamond): Contains a condition (e.g., "Is Condition True?"). It has two exit paths: one for "True" and one for "False". Flow Line (Arrow): From the "True" path of the Decision symbol to a Process symbol. Process Symbol (Rectangle): Represents an action or set of actions to be performed if the condition is true (e.g., "Execute True Block"). Flow Line (Arrow): From the "False" path of the Decision symbol to another Process symbol. Process Symbol (Rectangle): Represents an action or set of actions to be performed if the condition is false (e.g., "Execute False Block"). Flow Lines (Arrows): From both Process symbols (True Block and False Block) to a common point. Flow Line (Arrow): From the common point to the End symbol. End Symbol (Oval): Marks the end of the process. Send me the next one 📸
