Memory device operating speed is measured in cycle time which is the amount of time required for memory to perform read and write operation and return to its original state ready for next operaiton.
Access time is another measure of memory speed which is only the time required for read operation or it is the time between data receiving (read operation) and the data becoming available at the memory output.
A user memory for an operating system are the devices in which data is stored. These devices can be built into the computer, such as the hard drive, or they can be an external device, such as a USB pen drive or external hard drive.
The term "nexus" typically refers to a central connection or link, but it is not commonly used to describe the core of an operating system. The core component of an operating system that manages memory and devices is usually called the kernel. The kernel is responsible for resource management, including memory allocation, device communication, and process scheduling, ensuring that hardware and software can interact efficiently.

so as to infom the processor of what it ought to do
what manages the computers hardware? THE TEXTBOOK ANSWER IS THE OPERATING SYSTEM
Generally it's called "booting up" the system. It's also how we got the term "Rebooting". It can also be called "mounting" however this term generally applies more to specific hardware devices.
The different resources of operating system are file system,input/output devices,memory unit,processor....
There are several components of the operating system which facilitate the proper functioning of a computer system. The main component if the kernel which is broken down into CPU, memory and other devices.
because it does simultaneous action for accessing the memory.
The operating system resides in secondary memory i.e., hard disk.when we boot our computer it is loaded into Primary memory i.e.,RAM and then loaded,this process is called booting
