What is Cyber Attack?
Cyber Attack is any intentional effort to steal, expose, alter, disable, or destroy data, applications or other assets through unauthorized access to a network, computer system or digital device.
Threat actors launch cyber attacks for all sorts of reasons, from petty theft to acts of war. They use a variety of tactics, like malware attacks, social engineering scams, and password theft, to gain unauthorized access to their target systems.

What is a computer network and explain the different type of network?

A computer network is a collection of interconnected computers and other devices that are capable of sharing data and resources with each other. These networks can vary in size and complexity, from small local networks within a home or office to vast global networks like the internet. Computer networks allow users to communicate, share files, access resources, and collaborate on various tasks. They are essential for modern communication and information sharing.

Below are few types of networks:

Local Area Network (LAN):LANs are typically confined to a small geographic area, such as a single building or a campus. They provide high-speed data transfer rates and are used for connecting devices within a home, office, or organization. Ethernet and Wi-Fi are common technologies used in LANs.

Wide Area Network (WAN): WANs cover a broader geographic area, often connecting LANs across different cities or even countries. They rely on various technologies, including leased lines, satellite links, and the internet, to connect distant networks. WANs enable global communication and data sharing.

Metropolitan Area Network (MAN): MANs have a size and coverage between LANs and WANs, typically serving a city or a large campus. They are used to interconnect multiple LANs within a metropolitan area. Fiber optics and wireless technologies are often employed in MANs.

Wireless Local Area Network (WLAN): WLANs use wireless technology (Wi-Fi) to connect devices within a limited area, such as a home, office, or public hotspot. They provide flexibility and mobility as devices can connect without physical cables.

Personal Area Network (PAN): PANs are small, short-range networks designed for personal devices like smartphones, tablets, and laptops. Bluetooth is a common technology used for PAN connections.

Virtual Private Network (VPN): VPNs create secure, encrypted connections over public networks like the internet. They are used to ensure privacy and security when transmitting data over potentially insecure channels.

Intranet: An intranet is a private network that uses internet technologies and protocols to share information within an organization. It is used for internal communication, document sharing, and collaboration.

Extranet: An extranet is an extension of an intranet that allows limited external access to certain parts of an organization's network. It’s often used for collaboration with external partners or suppliers.

Client-Server Network: In a client-server network, one or more powerful servers provide services or resources to client devices. Common in business environments, where servers store data and manage user access.

Peer-to-Peer Network (P2P): P2P networks distribute the workload evenly among connected devices, allowing them to act as both clients and servers. Often used for file sharing, instant messaging, and distributed computing.
