In both cases, the result is a large system. o A distributed system is a collection of independent computers that appear to the users of the system as a single coherent system. DISTRIBUTED SYSTEMS 5 TIP: USE CHECKSUMS FOR INTEGRITY Checksums are a commonly-used method to detect corruption quickly and effectively in modern systems. Because of this reason few firms had less number of computers and those systems were operated independently as there was a lack of knowledge to connect them. 7.
