OSI and TCP/IP models are networking models that define how data is transmitted over a network.
OSI model has 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, Application
TCP/IP model has 4 layers: Network Interface, Internet, Transport, Application
OSI model is theoretical while TCP/IP model is practical and widely used
OSI model helps in understanding how data flows in a network, while TCP/IP mod
DHCP stands for Dynamic Host Configuration Protocol. It is a network protocol that automatically assigns IP addresses to devices on a network.
DHCP assigns IP addresses to devices on a network
It helps in managing and organizing IP addresses efficiently
DHCP reduces the need for manual configuration of network devices
DHCP lease time determines how long an IP address is assigned to a device
Example: When a new device connec...
VLAN, STP, VTP, and EtherChannel are networking concepts used to manage and optimize network traffic.
VLAN (Virtual Local Area Network) divides a physical network into multiple virtual networks to improve performance and security.
STP (Spanning Tree Protocol) prevents loops in Ethernet networks by blocking redundant paths.
VTP (VLAN Trunking Protocol) manages VLAN configurations across a network to ensure consistency.
Ethe...
IP addressing is a method used to assign unique numerical labels to devices on a network, while subnetting involves dividing a network into smaller subnetworks.
IP addressing is used to uniquely identify devices on a network using a series of numbers separated by periods (e.g. 192.168.1.1).
Subnetting involves dividing a larger network into smaller subnetworks to improve performance and security.
Subnet masks are used to ...
DNS stands for Domain Name System, which translates domain names to IP addresses.
DNS is like a phone book for the internet, translating human-readable domain names (like google.com) to IP addresses (like 172.217.3.206).
It helps users access websites and other online services by resolving domain names to their corresponding IP addresses.
DNS also helps in email delivery, ensuring that emails are sent to the correct mail ...
Routing is the process of selecting the best path for network traffic to reach its destination.
Routing involves determining the optimal path for data packets to travel from the source to the destination.
Routers use routing tables to make decisions on how to forward packets.
Routing protocols like OSPF and BGP are used to exchange routing information between routers.
Examples of routing devices include routers and layer 3
A switch is a networking device that connects devices within a local area network (LAN) and forwards data packets between them.
Switch operates at the data link layer of the OSI model
It uses MAC addresses to forward data to the correct destination
Switches improve network performance by reducing collisions and segmenting traffic
Examples: Cisco Catalyst switches, Juniper EX Series switches

The new operator is used to dynamically allocate memory for an object at runtime.
It returns a pointer to the newly allocated memory.
It can be used to allocate memory for built-in types, user-defined types, and arrays.
The syntax is: new type;
Example: int *ptr = new int;
Example: MyClass *obj = new MyClass();
