You saved the document to your “Documents” folder. Let’s say, for example, that you’ve been typing a document on Microsoft Word. All the bytes that make up your computer files live in storage. Storage is a very important neighborhood. Let’s talk about that suburban neighborhood on the outskirts of town: storage.

Serial communication allows the storage drive to queue incoming data.The cables are built with “dividers” that prevent magnetic field interference.The cables are smaller, which gives computer manufacturers greater flexibility when designing the computer’s architecture.Serial communication remedies these problems: This causes the data to be communicated more slowly, or not at all sometimes. When two cables run parallel to each other, their magnetic fields disrupt each other’s data transmissions. Electric currents create small magnetic fields. Multiple cables took up a lot of space inside the computer.The nice thing about parallel communication was that each highway had a large number of lanes and could handle more traffic at once. Imagine having 2 highways, one with only northbound lanes, and the other with only southbound lanes, with the highways located a mile apart from one another. In the days of parallel communication, incoming data and outgoing data were transmitted through separate cables. Serial communication replaced parallel communication, which is now obsolete in most computers. Data can be transferred from storage to the motherboard.Data can be transmitted from the motherboard to storage.Serial communication means that the highway has both northbound and southbound (or, eastbound and westbound) lanes: īoth SAS and SATA utilize serial communication. But each is built a little differently, and so the speed of traffic is different on each one.

SAS and SATA are both highways in our analogy. One of these highways in your computer connects the motherboard with storage. More lanes equal a better flow of traffic. The best highways have a large number of lanes.

The pulse reflects whatever the file’s binary code is.Ī computer bus is a superhighway that connects different parts of the city. Whenever data is relayed around the computer, your computer sends a flickering electrical pulse along the copper wires (connectors) that connect different hardware units.

Computer files are made from thousands - or hundreds of thousands, or millions - of bytes.

When there’s no electric current, you get a 0.

When there’s an electric current flowing, you get a 1.Everything on your computer - again, documents, photos, videos, software, web browsers, visuals - are composed of bytes.Ī byte is really nothing more than an electric pulse: Each individual person is called a “byte.” A byte is data. Let’s talk about the people who live in the city. Everything on your computer - documents, photos, videos, software, web browsers, visuals - is composed of a unique combination of 0s and 1s. It’s a simple language that’s composed of only 2 numbers: 0s and 1s. Likewise, electricity travels smoothly on metal surfaces.īinary code is the language that’s spoken in St. In a computer, the roads are made of metal, like copper wire. In the real world, roads are usually made from concrete or asphalt. They link all the neighborhoods together. It’s called “storage.” Like real-life suburbs, storage is where lots of people settle down and live the quiet life.Ĭonnectors are the roads in St. A large suburb is located on the outskirts of the motherboard.
