Computer security and locking refers to the measures and protocols put in place to protect a computer system and its data from unauthorized access, use, or modification. This can include using passwords, encryption, firewalls, and other security measures to prevent unauthorized users from gaining access to sensitive information. Locking refers to the act of securing a computer system or specific files and folders to prevent unauthorized access, often through the use of passwords or biometric authentication. These measures are essential for protecting sensitive information and maintaining the integrity and confidentiality of data. **

The storage space on your computer was likely increased by a technician or by yourself if you added a new hard drive or upgraded the existing one. Increasing storage space can also be done by adding an external hard drive or utilizing cloud storage services. It is important to ensure that the new storage space is properly installed and configured to work seamlessly with your computer. **

You can create an iPhone backup without a computer by using iCloud. To do this, go to your iPhone's settings, tap on your Apple ID at the top, then select iCloud.

Additionally, many web browsers also have a downloads history feature where users can manage and delete their downloaded files. Therefore, it is still possible and relatively easy to delete downloads on a computer. **

Studying computer science can definitely help individuals achieve IT security. By understanding the fundamentals of computer systems, networks, and programming, individuals can develop the necessary skills to identify vulnerabilities, implement security measures, and protect systems from cyber threats. However, achieving IT security also requires specialized knowledge in cybersecurity, which focuses specifically on protecting digital information and systems. Therefore, while studying computer science is a great foundation, individuals may need to further specialize in cybersecurity to fully ensure IT security. **

The biggest security risk in a computer network is often human error or negligence. This can include clicking on malicious links or attachments, using weak passwords, or falling victim to social engineering attacks. Additionally, outdated software and lack of regular security updates can leave vulnerabilities that hackers can exploit. It is crucial for organizations to educate their employees about cybersecurity best practices and implement robust security measures to mitigate these risks. **

It is possible that Norton Security Scan was pre-installed on your computer as part of a software bundle or as a trial version. Alternatively, it could have been downloaded and installed by someone with access to your computer. Norton Security Scan is a legitimate antivirus program that helps protect your computer from malware and other security threats. If you did not intentionally install it, it is important to verify its legitimacy and consider running a full system scan to ensure your computer is secure. **
