Acceptance sampling is used by industries worldwide for assuring the quality of incoming and outgoing goods. Acceptance sampling plans determine the sample size and criteria for accepting or rejecting a batch based on the quality of a sample, using statistical principles. Many organizations require the use of ISO standards (or their ANSI/ASQC/BS/Military Standards or other counterparts) for purposes of certification. Below are online versions of Military Standard Tables (equivalent to the civilian ISO/ANSI/ASQC/BS standards), which greatly simplify the process of determining sampling plans. You can find out how many items to sample and inspect, and how to decide whether the entire batch should be accepted or rejected.
A process control is a popular statistical tool for monitoring the quality of goods and services, and for detecting when the process goes "out of control" as early as possible. Samples from the process are taken every time interval, and their quality measured. Control charts are used to track the sample quality over time and detect any unusual behavior. Below are calculators that help you to easily obtain the control chart limits for different types of measurements.

I believe that servo is motorized and solenoid is magnetically activated.

There is no difference between PCC ( Power Control Centre) and PDB (Power Distribution Board). Although they have different names, but their functions are same i.e. controlling power feeders.
In in- bandsignalling , the control and management signals travles along with the data signals where as in out of band signalling the data and control signals travels in different channels
Sampling plans are hypothesis tests regarding product that has been submitted for an appraisal and subsequent acceptance or rejection. A control chart is used to track a process with time to determine if the problems are sporadic or chronic.
The main difference between the quota and stratified sampling is that in the stratified sampling the researcher can not select the individuals to be included in the sample (he doesn't have control over who will be in the simple), but in the quota sampling the researcher has control over who will be in the sample (he can contact certain people and include them in the sample).
Difference between restricted sampling and unresticted sampling
Random sampling is the sample group of subjects that are selected by chance, without bias. Random assignment is when each subject of the sample has an equal chance of being in either the experimental or control group of an experiment.
difference between feedback and control
The objective of acceptance sampling is to determine whether a batch of products meets predetermined quality standards without inspecting every individual item. By assessing a representative sample, it allows for efficient quality control while minimizing inspection costs and time. This method helps organizations make informed decisions about accepting or rejecting entire lots based on the observed quality of the sample. Ultimately, acceptance sampling aims to balance the risks of accepting defective products and rejecting acceptable ones.
Difference between control process and process control is that system control process is typically the large scale version of where process control is used.
Their is no Difference
The four types often named are Acceptance Sampling, Statistical Process Control, Process Audits, and Product Inspection. You check batches, watch performance data, review steps, and inspect finished products to catch or prevent issues.
