Assembly value objdump -d

I am trying to understand what all the elements of this objdump -d mean.

for example me:

08048b50 <phase_1>:
8048b50:    83 ec 1c                sub    $0x1c,%esp
 8048b53:   c7 44 24 04 68 a2 04    movl   $0x804a268,0x4(%esp)
 8048b5a:   08 
 8048b5b:   8b 44 24 20             mov    0x20(%esp),%eax
 8048b5f:   89 04 24                mov    %eax,(%esp)
 8048b62:   e8 63 04 00 00          call   8048fca <strings_not_equal>
 8048b67:   85 c0                   test   %eax,%eax
 8048b69:   74 05                   je     8048b70 <phase_1+0x20>
 8048b6b:   e8 f5 06 00 00          call   8049265 <explode_bomb>
 8048b70:   83 c4 1c                add    $0x1c,%esp
 8048b73:   c3                      ret

In particular, I'm not sure what the 1st and center speakers are telling me

The first column shows the memory addresses where the code will be located at runtime.

The second column has a hexadecimal version of the executable command.

The third (and fourth) columns have a disassembled version of the second column. i.e. operation code and operands.
