There is nothing about the IBM symbol, for example, that suggests computers, except what the viewer reads into it. Stripes are now associated with computers because the initials of a great computer company happen to be striped.
I hate to disagree with legends of their fields, but the IBM logo did make people think computers because the stripes looked like things that were familiar from computers of the era.
For example, it was common for computer displays at the time to have space between the character lines. If you tried to create the letters IBM in a very large size on an early computer terminal, you would get lines between them because room was left for character descenders.
I had relatives who worked for IBM in upstate New York in the 60's through the 80's, and they identified the stripes as being reminiscent of the green bar printer/ teletype/ terminal paper that was commonly used.
