grep -ow 'lm' /proc/cpuinfo | sort -u

NOTE: 64-bit is not necessarily better (it's a matter of context).

What is the output of:-
df -h

What is the output of:-

What is the output of:-
du -h /var/cache/apt/archives

What is the output of:-
cat /etc/apt/sources.list{,.d/*}|grep '^[^$\|^#\|^\s*\#]'|sed 's/^ deb/deb/'

What is the output of:-
for i in /etc/apt/preferences{,.d/*};do echo $i;cat $i;echo " ";done

Kind regards
