We use fixed partitioning for a main memory (M) of size 1GiB. Each same sized partition is of the same size 256KiB. The machine is a 32-bit architecture.1. How many partitions do we have for M? 2. A logical address is thus split into a partition number and partition offset within that partition. How many bit for the partition number ? 3. A logical address is thus split into a partition number and partition offset within that partition. How many bit for the partition offset ?

We use fixed partitioning for a main memory (M) of size 1GiB. Each same sized partition is of the same size 256KiB. The machine is a 32-bit architecture.1. How many partitions do we have for  M? 2. A logical address is thus split into a partition number and partition offset within that partition. How many bit for the partition number ? 3. A logical address is thus split into a partition number and partition offset within that partition. How many bit for the partition offset ?  4. We store the information related to the partitions in a table PaT. PaT has one entry per partition. Thus PaT[ i ] shows the PID of the process occupying that partition. PID are linux PIDs and we provided some information about them in Subject 3 when we discussed the Process List. A PID consists of a number of bit that is a power of two multiple of the number of bit of a byte i.e. 8bit, 16bit, 32bit, etc. What is the length of the  PaT table/array ?  5.
