PC – Personal computer
Stands for “Personal computer“And it was one of the symbols of the computer revolution, milestone in the democratization of computer technology. Born to be accessible, economic And easy to usebrought the computer out of the offices and inside the houses; It was developed to be small enough, cheap and simple to use for the average consumer, facilitating the transition from technical complexity to the mass market. The term began to shoot in the 70s, when computers really began to be within everyone’s reach.
Cd – compact disc
The “compact disc“, introduced in the early 80s by Sony and Philips, two giants in the sector, revolutionized the music Thanks to its ability to archive digital audio. The CD in fact quickly replaced cassettes and vinyl records thanks to the higher audio quality and the longer duration of the support, becoming the dominant standard for music distribution and then for software and video games.
HD – Hard Disk
In Italian also called “hard disk“, It is the fundamental component for thedata storage In computers. Invented by IBM in 1956, the HD allowed to store enormous quantities of data compared to previous methods, becoming fundamental on computers for decades, until today, where we often see it replaced by SSD (Solid State Drive), remains a historical piece of tech evolution.
USB – Universal Serial Bus
This connection system was born in 1996 to simplify the connection of peripherals such as mouse, keyboards, printers. In the form of what we commonly call “sticks” also serves to transfer data. The USB interface is also used to load devices, and has played a crucial role in supporting data transmission and power supply.
RAM – Random Access Memory
The RAM, or the “Random access memory“, It is a volatile memory that allows the computer to process data quickly during operation. Being volatile, the data are lost when the diet is off.
CPU – Central Processing Unit
It is the “brain” of the computer. He carries out most of the calculations and elaborations, said “Central processing unit“, but also known as”processor“, He is responsible for the execution of the software instructions given by the programs and the operating system.
GPS – Global Positioning System
It is a global positioning system based on satellites, created in the 70s for military purposes, today it is essential for navigation by car, boats and planes, and is also used widely in common applications such as smartphones, fitness trackers and geographical mapping.
Wi-Fi-Wireless Fidelity
Wi-Fi means a wireless communication technology that allows the Internet connection of electronic devices via radio waves. It was officially introduced in 1999 and radically transformed the accessibility and convenience of use of the Internet, allowing the elimination of cables and providing a much greater freedom of movement both in domestic and public environments.
SSD – Solid State Drive
It is a “solid state unit” for the storage of data that uses the flash memory instead of traditional magnetic rotating discs. SSDs are faster, silent, impact resistant and reliable than traditional HDs. They have become the favorite standard especially for laptops and portable devices thanks to their characteristics of high performance and low energy consumption
LAN – Local Area Network
It is a local network which connects more devices within one limited area like a building or campus. It allows quick and safe communication between computers, facilitating the sharing of resources such as printers, files and Internet connection.
