Class is a blueprint or template for creating objects that define their properties and behaviors.

• Classes are used in object-oriented programming.

• They define the attributes and methods of an object.

• Objects are instances of a class.

• Classes can inherit properties and methods from other classes.

• Examples of classes include Person, Car, and Animal.

Class is a non-primitive data type used in object-oriented programming.

• A class is a blueprint for creating objects that have similar properties and methods.

• It can contain variables, methods, constructors, and other classes.

• Examples of classes include String, Integer, and ArrayList in Java.

A network is a collection of interconnected devices that communicate and share resources.

• Networks can be wired (e.g., Ethernet) or wireless (e.g., Wi-Fi).

• They enable data sharing between devices like computers, printers, and servers.

• Common types include LAN (Local Area Network) and WAN (Wide Area Network).

• Protocols like TCP/IP govern how data is transmitted over networks.

• Examples include home networks connecting device...read more

LAN (Local Area Network) connects devices in a limited area, while WAN (Wide Area Network) connects devices over larger distances.

• LAN typically covers a small geographic area, like a home, office, or campus.

• WAN spans larger distances, connecting multiple LANs, often across cities or countries.

• LANs use Ethernet or Wi-Fi technologies, while WANs may use leased lines, satellite links, or VPNs.

• Examples of LAN: a home netwo...read more

The OSI model has seven layers that standardize network communication protocols.

• 1. Physical Layer: Deals with hardware transmission (e.g., cables, switches).

• 2. Data Link Layer: Manages node-to-node data transfer (e.g., Ethernet).

• 3. Network Layer: Handles routing of data packets (e.g., IP).

• 4. Transport Layer: Ensures reliable data transfer (e.g., TCP, UDP).

• 5. Session Layer: Manages sessions between applications (e.g., A...read more

Sharing of recourse information from one divice to another device And Types Communication Simplex. One way communication Half duplex. Two way communication but not simultaneously Full duplex. Two way communication simultaneously

Various types of attacks in a network include DDoS, phishing, malware, man-in-the-middle, and SQL injection.

• DDoS (Distributed Denial of Service) attack overwhelms a network with traffic.

• Phishing attack tricks users into revealing sensitive information.

• Malware attack involves malicious software infecting a network.

• Man-in-the-middle attack intercepts communication between two parties.

• SQL injection attack exploits vulnera...read more

DDOS, Virus, and Worm are types of cyber threats that can harm computer systems and networks.

• DDOS stands for Distributed Denial of Service, where multiple compromised systems attack a target, causing a denial of service for users.

• A virus is a malicious software program that replicates itself by inserting copies into other programs or documents.

• A worm is a self-replicating malware that spreads across networks without ne...read more
