Neco 2025 Computer Studies Question 7
Practice objective / multiple choice question 7 from the 2025 Neco Computer Studies examination.
An 11‑bit sequence is transmitted as follows: the first 8 bits are data, bit 9 is an even‑parity bit for the data, and bits 10‑11 form a 2‑bit checksum equal to the sum (mod 4) of the decimal values of the first two 4‑bit nibbles. The received sequence is \(10110011001\). Determine whether a transmission error occurred and, if so, identify the erroneous bit position (counting from the left, 1‑indexed).
