“In its most basic form, a computer is a collection of powered ... “Computers add numbers together using logic gates built out of transistors. But they don’t have to be!

Logic gates are the bricks and mortar ... As with relays, all kinds of logic circuits were made using vacuum tubes. There were 17,468 of them in the ENIAC computer. Tube circuits were bulkier ...

I’ll start with logic symbols, alternate symbols, small Boolean truth tables and some oddball things that we can do with basic logic ... also such as the NAND gate shown here.

Now it is actually possible to use transistors ... three basic boolean gates. We know we have two inputs again -- A and B -- and one output. Let's start with an OR gate, since the logic table ...

To use logic gates ... in a computer's memory, NOR gates are used to store data in a form known as complementary metal-oxide-semiconductor (CMOS). The AND Gate is another basic logic gate that ...

A long-cherished dream is to develop logic gates in which signal transmission takes place using photons instead ... Pankaj Dharpure have demonstrated the basics for the purely optical processing ...

While previous research had already proven biological logic gates could be ... XNOR), which play a basic role in the design of computer chips, can be implemented by using a combination of NAND ...

The same basic tools that allow computers to function ... has created artificial proteins that function as molecular logic gates. These tools, like their electronic counterparts, can be used ...

Networks programmed directly into computer chip hardware can identify images faster, and use much less ... networks composed of logic gates, which are some of the basic building blocks of computer ...
