Question
Define the term:
i. “Data Transmission”. (2 Marks)
ii. “Data warehouse”. (2 Marks)
iii. Explain the term “Error Detection” in relation to data transmission and list four error detection algorithms. (6 Marks)
Answer
i. Data Transmission:
Data transmission is the process of sending and receiving data or information from one point to another through a communication channel such as a wired or wireless medium.
ii. Data Warehouse:
A data warehouse is a centralized repository for storing large volumes of structured and organized data, typically used for analysis and reporting purposes.
iii. Error Detection:
Error detection refers to the process of identifying errors in data transmission to ensure that the data received is accurate and free from corruption. It is crucial in maintaining data integrity during communication.
Error Detection Algorithms:
-
- Parity Check
- Checksum
- Cyclic Redundancy Check (CRC)
- Hamming Code
