Computer mounting multiple modules facilitating opening/expansion control process with connectors

A computer comprising each having a first order of lanes:

• a plurality of first modules;
• a plurality of second modules, each having a second order of lanes reverse to the first order of lanes, configured to expand a function for each of the plurality of first modules;
• a plurality of first connectors, each having a first order of lanes and each connectible to each of the plurality of first modules;
• a plurality of second connectors, each having a second order of lanes and each connectible to either the first module or the second module;
• and
• a plurality of data transmission lines configured to connect the plurality of first connectors to the plurality of second connectors via a plurality of lanes,
• wherein the plurality of first connectors and the plurality of second connectors are alternately aligned in a first direction and connected together via the plurality of data transmission lines,
• wherein the plurality of first connectors or the plurality of second connectors are aligned in a second direction perpendicular to the first direction, and
• wherein the first module connected to the first connector recognizes the second module through the data transmission line only when the second module is connected to the second connector, thus expanding the function of the first module using the second module.

A connector set detachably attached to either a first module having a first order of lanes or a second module having a second order of lanes reverse to the first order of lanes and configured to expand a function of the first module, comprising:

• a first connector having the first order of lanes and connectible to the first module;
• a second connector having the second order of lanes and connectible to either the first module or the second module;
• and
• a data transmission line configured to connect the first connector to the second connector via a plurality of lanes,
• wherein the first module connected to the first connector recognizes the second module through the data transmission line only when the second module is connected to the second connector, thus expanding the function of the first module using the second module.
