'Sequential', 'System' and 'Structured' are not part of the name.

IoT stands for Internet of Things.

The Internet of Things is the network of everyday physical objects, such as lights, thermostats, door locks, cameras and appliances, fitted with sensors and connectivity so that they can collect and exchange data and be controlled over the internet. Smart homes are a common example.

'Integration' and 'Technologies' are not part of the term; the 'things' are the connected physical devices.

RAM means Random Access Memory: any memory location can be read or written directly, in about the same time, without going through the locations before it. It is volatile, losing its contents when the power is switched off.

'Read' belongs to ROM, Read Only Memory, which is non-volatile. 'Resource' and 'Retention' are not part of the term.

MSI stands for Medium Scale Integration.

Integrated circuits are classified by how many components (transistors or logic gates) are placed on one chip: SSI (small scale integration, up to about 10 gates), MSI (medium scale integration, roughly 10 to 100 gates), LSI (large scale), VLSI (very large scale) and beyond. MSI chips include counters, multiplexers and decoders.

'Medium Scale Integrated' uses the adjective instead of the noun; the I in SSI, MSI, LSI and VLSI is always integration. 'Micro-star Integrated' and 'Medium Scale Intelligent' are not terms used in electronics.
