1 You are connected to the SOHO network with three devices computer A and a laptop. Both devices are connected to an integrated router. he laptop connects wirelessly to the IR Computer A is connected via an Ethernet cable Computer A want to send a message to the laptop. lowever it replies with an error message notifying that it cannot send the message. Elaborate on the necessary troubleshooting steps to use \( t \) larrow down the problem and resolve the error message with the aid of a ticket report (25)

2. Изобразнте систему координат в пространстве и \( \mathrm{A}(1 ;-2 ; 4) \). Найдите длину \( \overrightarrow{\mathrm{a}}=2 \overrightarrow{\mathrm{i}}-4 \overrightarrow{\mathrm{k}}+\overrightarrow{\mathrm{j}} \). Найдите координаты \( 2 \overrightarrow{\mathrm{a}}+3 \overrightarrow{\mathrm{~b}} \), если \( \overrightarrow{\mathrm{a}}\{2 ; 0 ;-3\}, \overrightarrow{\mathrm{b}}\{5 ;-1 ; 2\} \).
