MVVM (Model-View-ViewModel) is a design pattern used in Swift to separate the user interface logic from the business logic.
MVVM divides the code into three main components: Model, View, and ViewModel.
Model represents the data and business logic of the application.
View displays the data and interacts with the user.
ViewModel acts as a mediator between the Model and View, handling the logic for the View.
MVVM helps in maki...
Multithreading is the ability of a CPU to execute multiple threads concurrently, allowing for improved performance and responsiveness in applications.
Multithreading allows multiple tasks to be executed simultaneously on a single CPU core.
It can improve performance by utilizing idle CPU time for other tasks.
Examples include running background tasks while the main thread handles user interactions in an iOS app.
I was interviewed before Mar 2021.

Ensure to consider the constraints on the length of the string and the
A deadlock is a situation in which two or more processes are unable to proceed because each is waiting for the other to release a resource.
Occurs in multitasking environments where processes compete for limited resources
Can be resolved using techniques like deadlock prevention, deadlock avoidance, and deadlock detection
Example: Process A holds Resource X and waits for Resource Y, while Process B holds Resource Y and wa
A thread is a lightweight sub-process that allows concurrent execution within a single process.
Threads share the same memory space within a process.
Threads are used to achieve parallelism and improve performance.
Examples of threads include the main thread in a program and worker threads in a multi-threaded application.
Multiprocessing involves multiple processors executing multiple tasks simultaneously, while multiprogramming involves multiple programs sharing a single processor by switching between them.
Multiprocessing utilizes multiple processors to execute multiple tasks concurrently.

Process life cycle in an operating system involves creation, execution, termination, and resource management.
Creation: When a process is created, it is assigned a unique process ID and allocated necessary resources.
Execution: The process is then scheduled by the operating system to run on the CPU.
Termination: Once the process completes its task or is terminated by the user, it is removed from memory.
Resource Management...

Technical round with questions on DBMS and Networking mainly.
RDBMS is a type of DBMS that stores data in a structured format with relationships between tables.
RDBMS enforces referential integrity and allows for normalization of data.
DBMS is a general term for any system that manages databases, while RDBMS specifically refers to relational databases.
Examples of RDBMS include MySQL, Oracle, and SQL Server.
Examples of DBMS include MongoDB and Redis.
An Object-Oriented Database Management System (OODBMS) is a type of database management system that supports the creation and management of objects in a database.
OODBMS stores data in the form of objects, which can contain attributes and methods.
It allows for complex data structures and relationships to be represented more easily.
Examples of OODBMS include db4o, ObjectDB, and ObjectStore.
Use the COUNT DISTINCT function in SQL to find the number of unique values in a database.
Use the COUNT DISTINCT function along with the column name to count the number of unique values in that column.
For example, SELECT COUNT(DISTINCT column_name) FROM table_name;
You can also use GROUP BY to find the number of unique values for multiple columns.
A hub operates at the physical layer and broadcasts data to all devices on the network, while a switch operates at the data link layer and forwards data only to the intended recipient.

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven different layers.
Physical Layer: Deals with the physical connection between devices. Example: Ethernet cables.
Data Link Layer: Responsible for node-to-node communication. Example: MAC addresses.
Network Layer: Manages routing of data packets. Example: IP addresses.

Different protocols supported at each OSI layer
Layer 1 (Physical): Ethernet, Wi-Fi, Bluetooth
Layer 2 (Data Link): MAC, PPP, HDLC
Layer 3 (Network): IP, ICMP, ARP
Layer 4 (Transport): TCP, UDP, SCTP
Layer 5 (Session): NetBIOS, PPTP
