Study Notes

IP Addressing

IP addresses are numerical labels assigned to devices participating in a computer network that uses the Internet Protocol for communication.
IP addresses uniquely identify each device on the network.
There are two main versions of IP addresses: IPv4 and IPv6.
IPv4 addresses are 32-bit addresses, typically represented in dotted decimal notation (e.g., 192.168.1.1).
IPv6 addresses are 128-bit addresses, using a more complex hexadecimal representation (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
IP addresses are crucial for routing data packets across networks.
Subnetting divides large networks into smaller subnetworks, improving network management and security.
Static IP addresses are fixed addresses assigned to a device, while dynamic addresses are assigned temporarily.
Private IP addresses are used within a private network, not directly accessible from the internet.

Network Security

Network security involves protecting computer networks from unauthorized access, use, disclosure, disruption, modification, or destruction.
Firewalls control network traffic, blocking unwanted connections and protecting against malicious attacks.
Intrusion detection and prevention systems (IDS/IPS) monitor network traffic for malicious activity and take actions to block threats.
Network access control verifies the identity and authorization of users trying to access the network.
Encryption protects sensitive data transmitted over the network, ensuring confidentiality.
Secure protocols like HTTPS, SSH, and TLS protect communications between devices.
Data loss prevention (DLP) systems prevent sensitive data from leaving the network or being compromised.
Network segmentation isolates parts of a network to limit the impact of a security breach.
Authentication methods verify user identities to secure access to network resources.

Routing Protocols

Routing protocols enable routers to exchange information about network paths and determine the best paths for routing data packets.
Routing protocols allow routers to dynamically adjust routes based on network changes, ensuring efficient data transmission.
Examples of routing protocols include RIP (Routing Information Protocol), OSPF (Open Shortest Path First), BGP (Border Gateway Protocol), and EIGRP (Enhanced Interior Gateway Routing Protocol).
Different protocols have different characteristics and functionalities, each tailored to manage specific network requirements.
These protocols determine and maintain the routing tables within routers. Routing tables direct data packets to their intended destinations.

Virtualization Technologies

Virtualization technologies create virtual instances of computing resources, including servers, storage, and networks.
This allows running multiple virtual machines (VMs) on a single physical machine.
Hypervisors create and manage VMs, simulating hardware for each virtual environment.
Virtualization improves resource utilization, allows for workload consolidation, and facilitates disaster recovery.
Virtual networks allow creating virtual versions of physical networks, enabling isolation and security.
Virtual storage allows efficient use of storage resources and enhances data backup and recovery.
Increased scalability and agility, cost reductions, and improved security are key benefits of using virtualization technologies.

Network Troubleshooting

Network troubleshooting is the process of identifying and resolving problems with a computer network.
Starting with understanding the symptoms and what is not working, a systematic approach is key to identify source of the problem
Tools like network analyzers and packet sniffers can capture and examine network traffic to identify issues.
Protocol analyzers (like Wireshark) help to understand network communication details to identify errors in specific protocols.
Basic network configuration checks like IP addresses, DNS settings, and routing tables can be checked first.
Common network problems include connectivity issues, slow performance, and security breaches.
Troubleshooting steps often involve isolating the problem area, testing hypotheses, monitoring logs and analyzing results, and implementing corrective actions.
Maintaining accurate records of attempted solutions is crucial in ongoing problem-solving.
Network documentation, diagrams, and policies help to understand the configuration and processes more fully.
