The evolution of logistics technology has been a journey marked by significant advancements, transforming the way goods are managed, transported, and delivered. 

Here's a brief overview:

(i) Manual Systems: A manual system, in the context of business operations or information processing, refers to a system where data is processed and tasks are completed without the use of automated tools or software. Instead, they are completed by individuals through manual labour.

(ii) Introduction of Railways and Steamships: The 19th century saw the rise of railways and steamships, revolutionising long-distance transportation and enabling faster movement of goods over land and sea.

(iii) Telecommunications: In the early days of telecom, analog technology was used to convert voice sounds into electrical signals. However, the advent of digital technology in the 1960s and 1970s transformed voice signals into digital data, resulting in improved sound quality and more efficient use of available bandwidth.The  telephones in the late 19th and early 20th centuries facilitated better coordination between different points in the supply chain, improving communication and efficiency.

(iv) Computerization: The earliest known tool used in computation was the Abacus and it is thought to have been invented in 2400 BC. A number of devices based on mechanical principles were invented to help in computing leading to even analog computers. Computational theories also evolved with the advent of logarithms etc. The latter half of the 20th century saw the rise of computers, which revolutionised logistics with capabilities like inventory management, route optimization, and automated tracking systems.
