What a ride it has been! In the beginning, we had Motorola’s DynaTAC, which was launched back in 1983 and weighed almost three pounds. Today, we carry miniature portable computers in our pockets, and they’re packed with fantastic technologies. Let’s explore the main components under their hoods.

The ‘heart’ of each smartphone is its CPU, a super-fast processor that can perform trillions of operations per second. The faster the CPU, the snappier the phone.

There are two types of memory inside your phone. Random Access Memory, aka RAM, is the short-term memory used to store things the CPU is currently working with; it’s erased if you restart the phone, for example. The second memory type is called storage memory; it is used to keep your data, apps, photos, videos, music, etc. for the long term.

The display consists of a high-resolution matrix of individual pixels that are controlled using a variety of technologies. Most phones use the OLED display technology these days.

The battery gives your phone the energy it needs to keep things running. It’s an accumulator that can be recharged 500 to 1,000 times before losing most of its capacity.

These key technologies work in harmony due to highly optimized software, turning smartphones into powerful tools for communication, work, and entertainment.
