Neco 2019 Data Processing Question 24
Practice objective / multiple choice question 24 from the 2019 Neco Data Processing examination.
A storage system records the time taken for a data‑access operation. A sequential access to the next block takes 5 ms. A random access consists of an unknown seek time \(S\) (ms) plus an unknown rotational latency \(R\) (ms). 70 % of accesses are sequential and 30 % are random. The measured average access time is 9 ms. Find the sum \(S+R\) (in milliseconds) of the unknown times.
