Here’s how to set an out of office reply in Gmail on your computer. 

You can no longer see a contact's last seen or online in the chat window.

  You do not see updates to a contact's profile photo.

  Any messages sent to a contact who has blocked you will always show one check mark (message sent), and never show a second check mark (message delivered). 

Any attempt to place will not go through.

If you try adding that person in a WhatsApp group you will notice an error message.

If you see all of the indicators above for a contact, this could mean that the user is blocking you. However, there are other possibilities. WhatsApp has made this intentionally ambiguous in order to protect your privacy when you block someone.

Step 2: Hold down Ctrl key (Cmd on macOS) and highlight the ones you need.

Step 1: Open your document in Google Docs or create a new one.

Step 2: Click File from the menu.

Step 3: Go to Download and select Microsoft Word (.docx) Document in the pop-out menu.

DRAM is memory that uses capacitor to store data and these capacitors have to constantly and dynamically be refreshed often with electricity in order for them to store data but there is another type of memory that computer uses that doesn't constantly have to be refreshed and this memory is called SRAM or static RAM. 

SRAM is what is used in CPU Cache and because SRAM doesn't have to be constantly refreshed it is a lot faster then DRAM and it's also very expensive.

  The CPU Cache is CPU's internal memory. It's job is to store copy of data and instructions from RAM that's waiting to be used by the CPU. CPU Cache holds common data that it thinks CPU is going to access over and over again because when CPU needs to access certain data it always checks the faster memory first to see if the data it needs is there. And if not then the CPU would have to go back to the slower primary memory or RAM to get the data it needs so that's why cache memory is so important. Therefore, storing the commonly required data in the cache is beneficial to increase the computation speed.
