Computers are electronic devices that process data to produce meaningful information. At their core, they consist of hardware (physical components like the processor, memory, and storage) and software (programs and operating systems that manage hardware and execute tasks). Understanding the basic structure and functionality of computers is crucial in the realm of cyber security, as threats often exploit vulnerabilities in these components.

In the context of cyber security, the key elements of a computer system—hardware, software, and networks—are potential targets for malicious activities. Hardware vulnerabilities, such as unprotected USB ports, can be exploited to introduce malware. Software vulnerabilities, including outdated operating systems or poorly coded applications, can create entry points for cyberattacks. Networks, which connect computers to one another and the internet, are a common avenue for cyber threats like phishing, ransomware, and Distributed Denial of Service (DDoS) attacks.

For instance, a compromised operating system could allow unauthorized access to…
