Child Care. What age to put your child into daycare is a personal decision and may depend on many factors. Such factors include: the length of your maternity leave; your partner's ability to take time off from work; your financial responsibilities; and whether you have other available childcare options, such as relatives.
Volatile memory is computer memory that requires power to maintain the stored information. Most modern semiconductor volatile memory is either static RAM (SRAM) or dynamic RAM (DRAM). SRAM retains its contents as long as the power is connected and is easy for interfacing, but uses six transistors per bit.
RAM is slower than even the slowest CPU cache, but it has much much more capacity (commonly 4GB to 16, or 32 or even 64 GB in commodity PCs). Upto this point in the memory hierarchy, the memory is volatile, meaning that if you switch off your computer you lose all the data.
