An accumulator machine, also called a single accumulator organisation , or a CPU with accumulator-based architecture, is a kind of CPU where, although it may have several registers, the CPU mostly stores the results of calculations in one special register, typically called "the accumulator". Historically almost all early computers were accumulator machines; and many microcontrollers still popular as of 2010

[1] the accumulator is meant to be an operand. so there is no requirement for the operand address field for one operand in the instruction. this results in short of CPU supports zero address instructions. Normally CPUs have two types of instructions:1)zero address2)single addressthe single address instruction have one operand in main memory and the other in accumulator.[2] instruction cycle takes less time. it saves time in instruction fetching due to the absence of operand fetching due to the absence of operand fetch.
a stack can be considered as a storage method in which then items are stored in consecutive memory loacations and the last element stored is the first element retrived ,also calles LIFO(last in First Out)list. you can visulise a stack as the number of plates placed one avove the other,when you want to place a new plate.you will place on the top of the reamining plates,when you want to withdraw a plate,you will out of the topmost plate first,that is the plate last kept is the first taken out or last in first out ,
8085 is a 8 bit microprocessor and so A register which is also known as accumulator is also 8 bit.

No you literally can not multitask with a single CPU, since one CPU can only process one task at a time, because with your 32-bit and 64-bit OS the OS allots CPU time to the application for a specific time then the OS preempts the processing to give the CPU to another application, the programs may appear to be multitasking but they are not, that is called preemptive multitasking.
It should be self-evident. It's a motherboard capable of supporting a single CPU.
In computers an accumulator is a dedicated single purpose register in which arithmetic operations are performed. They cannot be used for addressing memory or any other purpose than arithmetic. Different computers have different quantities of accumulators, from none to a few dozen depending on the architecture.
