How does Tech works?
Technology is everywhere in our lives these days, but few of us understand exactly how it works. Whether it’s the smart devices in our pocket, the connected gadgets in our homes, or the powerful computers at work, most of us take the wonders of tech for granted.
But how does this incredible technology really work and how did it come about? How does a computer calculate the data it receives so quickly? How does the internet transmit messages between devices, spanning the globe in just a few seconds?
One of the basic elements of tech is electricity, something that’s been around for centuries. Every device needs to be powered, either by a battery or a direct power supply. Inside each and every device are electrical circuits and chips, also known as integrated circuits.
These circuits use electric impulses, a type of energy, to complete tasks and process information. Every computer contains a Central Processing Unit, or CPU, which is responsible for most of the device’s calculations and processes. This is the “brain” of the computer, using a set of stored instructions or “software” to complete its tasks.
No machine works in isolation, however. All of our devices are connected, sending and receiving messages to transmit data across long distances. This is where the internet comes in.
The internet can be thought of as a gigantic spider web, with our devices connecting to larger devices like servers and routers. All data transmitted over the internet is processed through a series of networks, with each network acting like a bridge between our devices and the wider world.
These networks make use of a type of data transmission known as “packet switching” which splits messages into smaller pieces which are then sent independently to their destination. Network nodes then connect the pieces back together when the message is received.
The incredible speed and accuracy with which our devices transmit and receive data is possible mostly thanks to the development of faster and more powerful processors. Each new generation of processors is smaller, faster, and more efficient than the last, allowing our machines to tackle ever more complicated operations.
It’s clear that technology today is only as good as the engineers and developers that put it together. But even if we don’t understand the inner workings of our machines, it’s undeniable that without the hard work and dedication of those in the tech industry, the world of tomorrow wouldn’t be nearly as advanced or convenient as the one we live in today.
