can any one explain the following things?

Question

A machine has a 32-bit architecture, with 1-word long instructions. It has 64 registers, each of which is 32 bits long.

Answer 1

Machine has 32-bit architecture means machine can process maximum 32-bits data at a time.

here specified 1-word long instruction means size of instruction is 1-word i.e. 32-bits ( if there is no any specification then it will be a byte addressable by default.)

64 registers, each of which 32 bit long means in memory there are total 64 addresses and there cell size is 32-bits.

explain this more buddy
64 registers, each of which 32 bit long means in memory there are total 64 addresses and there cell size is 32-bits.?

(As per my knowledge it is 32 bit machine there is 2^32 memory address space .)

no 32 bit machine means it will process 32 bit data at a time

here no any relation with main memory address it may be byte addressable or word addressable according to memory design...
