An IP address is a unique identifier for a device on a network, enabling communication over the internet.

• An IP address can be IPv4 (e.g., 192.168.1.1) or IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

• IPv4 addresses consist of four octets, while IPv6 addresses are longer and use hexadecimal notation.

• IP addresses can be static (fixed) or dynamic (assigned by a DHCP server).

• They are essential for routing data betwe...read more

The OSI model is a conceptual framework used to understand and implement network communication protocols in seven layers.

• Layer 1: Physical - Deals with the physical connection (e.g., cables, switches).

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

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

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

• Layer 5: Session...read more

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

• 1. Physical Layer: Deals with the physical connection (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.,...read more

A Machine Learning pipeline is a structured process for developing and deploying ML models efficiently.

• Data Collection: Gather relevant data from various sources, e.g., databases, APIs, or web scraping.

• Data Preprocessing: Clean and prepare data by handling missing values, normalization, and encoding categorical variables.

• Feature Engineering: Select and create features that improve model performance, such as polynomial ...read more

Self-attention is a mechanism that allows models to weigh the importance of different input elements dynamically.

• Self-attention computes a weighted representation of input sequences, focusing on relevant parts.

• It uses three vectors: Query, Key, and Value to determine the importance of each input element.

• Example: In a sentence, 'The cat sat on the mat', self-attention helps the model understand the relationship between ...read more

DHCP is a network management protocol that automatically assigns IP addresses to devices on a network, simplifying network configuration.

• Dynamic IP Address Assignment: DHCP dynamically assigns IP addresses to devices, reducing the need for manual configuration.

• DHCP Server Configuration: A DHCP server can be configured using a GUI or command line, specifying IP address ranges and lease times.

• Example Configuration: In a ...read more

Active Directory is a directory service by Microsoft for managing users, computers, and resources in a networked environment.

• Centralized user management: Allows administrators to manage user accounts and permissions from a single location.

• Authentication and authorization: Verifies user identities and grants access to resources based on permissions.

• Group Policy management: Enables administrators to enforce security sett...read more
