1.      The only register which a process/ Programmer can read but not directly write to is the – instruction register

2.      In a hardwired control unit ´, the control signals for other computer units (esp. ALU) are created by the – generator matrix

3.      Modern CPU’s feature an integrated MMU order to maintain the – generator matrix

4.      The main components inside a control unit are the instruction counter, instruction register and the – instruction decoder

-        With smaller blocksizes (and hence more blocks/files), Inode tables become larger

-        RAID systems typically suffer from smaller blocksizes, due to data being fragmented across multiple disks

-        Larger logical blocksizes lead to lower IOPS rates

-        While on FAT each file-system object requires its own “directory enty”, on Ext2 each object requires an Inode

DARM:

·        Requires “voltage read” and “voltage write” units

·        Typically used for L3 caches

·        Leads to a “destructive read” if accessed

SRAM:

·        Is significantly faster and more expensive

·        Requires only a single flip-flop circuit

Uses row and column address decoder units
