1. Paging is a memory management technique used by operating systems to manage memory allocation for processes.
Paging divides memory into fixed-size pages and allocates them to processes as needed.
It allows for efficient use of memory and prevents fragmentation.
Page tables are used to keep track of which pages are allocated to which processes.
When a process needs to access a page that is not currently in memory, a page...

Example: @Repository interface UserRepository extends JpaRepository
A hash map is a data structure that uses a hash function to map keys to values in constant time.
Hash map uses an array to store key-value pairs
The hash function is used to convert the key into an index of the array
Collisions occur when two keys map to the same index, which is resolved using chaining or open addressing
Retrieving a value from a hash map involves computing the hash of the key and then looking up the corre...
Comparable is an interface used for natural ordering while Comparator is an interface used for custom ordering.
Comparable is implemented by the class itself while Comparator is implemented by a separate class.
Comparable provides a single method compareTo() while Comparator provides a single method compare().
Comparable is used for sorting elements in a collection while Comparator is used for custom sorting.
Example: Stri...
Concurrent Hash Map is a thread-safe implementation of a hash map.
It allows multiple threads to access and modify the map concurrently.
It uses a technique called lock striping to achieve high concurrency.
It is part of the java.util.concurrent package in Java.
Example: ConcurrentHashMap in Java.
I applied via Campus Placement and was interviewed in Jul 2024. There were 2 interview rounds.
They asked to find the elements which are present more than once. I solved it using map in c++
My favorite algorithm is Dijkstra's algorithm for finding the shortest path in a graph.
Dijkstra's algorithm is a greedy algorithm that finds the shortest path between nodes in a graph.
It works by maintaining a priority queue of nodes to visit next, updating the shortest distance to each node as it explores the graph.
The algorithm is commonly used in routing and network optimization.
Example: Finding the shortest route b
Deadlocks occur when two or more processes are unable to proceed because each is waiting for the other to release a resource.
Resource deadlocks: Processes hold resources and wait for others to release resources. Example: Process A holds resource X and waits for resource Y, while Process B holds resource Y and waits for resource X.
Communication deadlocks: Processes wait for messages from each other indefinitely. Example...

L2 and L3 switches are network devices used for packet switching. L2 operates at the data link layer and L3 at the network layer.
L2 switch operates at the data link layer and forwards packets based on MAC addresses
L3 switch operates at the network layer and forwards packets based on IP addresses
L2 switch is used for LAN networks while L3 switch is used for both LAN and WAN networks
L2 switch is faster than L3 switch as ...
MPLS is a protocol used for efficient packet forwarding in a network. It is used in WANs and service provider networks.
MPLS stands for Multiprotocol Label Switching
It is used to improve the speed and efficiency of network traffic routing
MPLS uses labels to identify the path that packets should take through the network
It is commonly used in WANs and service provider networks to provide Quality of Service (QoS) and traff...
VLANs are virtual LANs that allow network administrators to group devices together based on their functions or departments.
VLANs are used to segment a network into smaller, more manageable groups.
They can be created using network switches or routers.
Each VLAN has its own broadcast domain and can be configured with its own security policies.
VLANs can be created based on different criteria such as department, location, o...
