Doubt
Consider a system having 4K entries. LA = 29 bits. Calculate page size(PS)? Solution: I know that , PS = LAS/No. of pages ...............so, PS = 2^29 (bits)/2^12 = 2^17 KB How it comes as KB. I guess it should be 2^14 KB( dividing by 8 to convert it in bytes) Please tell me whether conversion is required or not. In some places i see the conversion and some places no conversion.
