i$)$ A General Purpose Computer can be used for a specific purpose by using software that is custom$-$developed for a specific application$/$purpose$.$

ii$)$ A memory unit whose locations can be identified using a $\text{'}k\text{'}-$bit address has an address$-$space of $\text{'}k\text{'}.$

iii$)$ The PC$-$Relative addressing mode offers more flexibility that the Base$+$Offset addressing mode in its ability to reference, any memory location as part of an instruction.

iv$)$ In LC$-3$ ISA, the Store instructions $($ST$/$STISTR$)$ do not have any impact to the condition code registers $($N$.$ Z$,$ P$).$

v$)$ Both DMA$-$based and Interrupt$-$driven IO techniques rely on the Interruptmechanism provided by the computer.
