The Von Neumann Architecture<\/p><\/div>\n

The first computers had fixed programs and changing a computer program required physically rewiring or redesigning the machine. This meant that re-repurposing an computer was a difficult, expensive and time-consuming process.<\/p>\n

The Mathematician John Von-Neuman designed the specification for the first programmable computer in 1954, where the programs themselves could be stored in memory, not just data.<\/p>\n

Instructions are stored in memory and are retrieved and processed by the Central Processing Unit one by one. This blueprint is known as the Von-Neumann Architecture.<\/p>\n

The Von-Neuman Architecture is based on the principle of:<\/p>\n
