Pretend you have a mountain of dirty clothes. You want to see the difference between washing dark and light colored clothing with warm and cold water. You need a sample because washing all of them takes too long.
Stratifying means you separate the clothes into dark and light colors and you pick a simple random sample from EACH color pile (this ensures you have the same number of clothes for both colors). Then you combine them into a miniature sample and you use RANDOM ASSIGNMENT to assign the clothes in the sample to either cold or warm water treatment.
Blocking also means that you separate the clothes into dark and light colors and you pick a simple random sample from each color pile. However, instead of combining it to make a miniature sample, you keep them separate and use random assignment WITHIN these blocks. Eg. for the dark color pile, you use random assignment to assign half to cold, half to warm water washing, and you repeat the same process for the light color pile, keeping them separate the entire time.

What is the difference between you are in the way and you are on the way?
in the way- you are blocking someone from getting to something or some other person. on the way- you are going someplace and will be there soon.
What is the difference between busy waiting and blocking process?
Busy waiting vs. Blocking Busy waiting is preferable when: Scheduling overhead is larger than expected wait time. Process resources are not needed for another tasks Schedule -based blocking is inappropriate (e.g in OS kernel)
What is the difference between blocking and building and accepting?
Blocking is where you ignore that fact that you are losing the argument against your friend, building is where you build together to find a way to sort things out and accepting is where accept that fact that you are losing that argument against your friend.

What is the difference between 1n4004 diode and 1n4007 diode?
The main difference between a 1n4004 and a 1n4007 are in the maximum RMS voltage, the maximum DC blocking voltage and the maximum repetitive peak reverse voltage. These are 280 and 700, 400 and 1000, and 400 and 1000 volts respectively.
What is the difference between blocking send and non-blocking send?
One of the first issues that you'll encounter when developing your Windows Sockets applications is the difference between blocking and non-blocking sockets. Whenever you perform some operation on a socket, it may not be able to complete immediately and return control back to your program. For example, a read on a socket cannot complete until some data has been sent by the remote host. If there is no data waiting to be read, one of two things can happen: the function can wait until some data has been written on the socket, or it can return immediately with an error that indicates that there is no data to be read.
How can I effectively implement horizontal blocking between studs in my construction project?
To effectively implement horizontal blocking between studs in your construction project, measure and cut the blocking to fit snugly between the studs. Secure the blocking in place using nails or screws, ensuring it is level and flush with the studs. This will provide additional support and stability to the structure.

Difference between shadow and reflection?
A shadow is the absence of light, a reflection is just that, the reflection of light. So a shadow comes from blocking a light source, a reflection comes from the bouncing of light of one source and on to another
