$1$ True$/$False $(10)$

$1\mathrm{.}1(,)$ Hardware means program and data

$1\mathrm{.}2(,)$ The analogy information is broken down into pieces, and each piece is represented separately

$1\mathrm{.}3(,)$ Main memory is nonvolatile $-$ stored information will be not lost if the electric power is removed

$1\mathrm{.}4(,)$ CPU continuously follows the decode$-$fetch$-$execute cycle

$1\mathrm{.}5(,)$ Sampling records discrete values of the analog representation

$1\mathrm{.}6(,)$ The digital information is represented and stored in memory using the binary number system

$1\mathrm{.}7(,)$ Main memory stores the instructions and data that are currently used by CPU

$1\mathrm{.}8(,)$ Main memory and disks are direct access devices $-$ information can be reached directly

$1\mathrm{.}9(,)$ Each computer has its own network address, which uniquely identifies it among the others

$)$ Java is an object$-$oriented programming language
