DNS, or Domain Name System, serves as the internet’s phone book, translating domain names into IP addresses that computers use to identify each other. It operates through a distributed database system, hierarchically organized, with DNS servers worldwide. These servers store domain name records and respond to queries from client devices, facilitating efficient internet communication. DNS … Read more

Wi-Fi security provides several benefits, including protecting sensitive information from unauthorized access and interception. By implementing encryption protocols such as WPA2 or WPA3, Wi-Fi networks ensure that data transmitted between devices and the access point is encrypted, reducing the risk of eavesdropping and data theft. This encryption helps maintain the confidentiality and integrity of data … Read more

SMTP (Simple Mail Transfer Protocol) offers several advantages in the realm of email communication. Its primary advantage lies in its efficiency and reliability for sending outgoing emails from a client device to a mail server and subsequently to recipients. SMTP ensures that emails are transmitted securely and promptly, facilitating quick delivery and enabling seamless communication … Read more

Network security involves protecting networks from unauthorized access, misuse, modification, or denial of service. It ensures data confidentiality, integrity, and availability within computer networks, including local area networks (LANs), wide area networks (WANs), and the internet. Network security measures include firewalls, encryption, intrusion detection systems, and VPNs to safeguard sensitive information and maintain network reliability. … Read more

The five types of network security include: Access Control: Regulates who can access the network and its resources, using authentication mechanisms like passwords, biometrics, and access control lists (ACLs). Firewalls: Acts as a barrier between a trusted internal network and untrusted external networks, filtering incoming and outgoing traffic based on predefined security rules. Encryption: Protects … Read more
