Networks and Distributed Processing
Vincent Walsh · 1985
In the early days of computing, when mainframes were the sole computer class and batch processing was the dominant use of the computer, separate data processing departments were formed around the computer hardware and programmers, systems analysts and other data processing specialists were employed. Under this system, work was given to the professionals by each department. The arrangement was, consequently, highly centralised with the hardware and the professional team as the focus and centre of all computing activities. This system used both centralised processing and a centralised organisational structure.
