In movies and TV shows, hackers are often depicted as being able to directly call a victim’s phone using their computer. This is a popular trope in movies and TV shows, but it is not based on reality. In real life, a computer cannot make phone calls directly to a phone number, unless it is connected to a phone line, or it is running specific software that enables it to make phone calls over the internet, such as Voice over IP (VoIP) software.
Also, in some movies or TV shows, hackers are shown breaking into a target computer or phone to gain access to their personal information, or to install malicious software that allows them to remotely control the device. This is also not entirely accurate, these scenarios are often fictionalized to create a more interesting story, and to make it more accessible to the audience.
In reality, hacking is a complex process that involves a wide range of techniques and tools, and it is not possible to achieve all of the capabilities depicted in movies and TV shows with a single click of a button.
