Neco 2025 Data Processing Question 25
Practice objective / multiple choice question 25 from the 2025 Neco Data Processing examination.
A data transmission uses 7‑bit ASCII characters with an added even‑parity bit, forming an 8‑bit byte. The character ‘I' (ASCII 73) is transmitted. Its correct 8‑bit code with even parity is therefore sent. During transmission a single‑bit error occurs and the receiver obtains the byte 01001001. Assuming at most one bit is wrong, identify the position (1 = leftmost) of the erroneous bit.
