The black screen of death refers to a computer or device screen that remains black and unresponsive.
It is similar to the blue screen of death (BSOD) in Windows systems.
It can occur due to various reasons such as hardware or software issues.
Common causes include graphics card problems, driver conflicts, or system crashes.
It can be resolved by troubleshooting hardware components, updating drivers, or performing system re...

Update drivers and operating system
Scan for malware or viruses
Check hardware components for issues
Perform system restore or reinstall operating system if necessary
Booting is the process of starting a computer system and loading the operating system into its memory.
Booting is the initial process that occurs when a computer is turned on or restarted.
During booting, the computer's hardware is initialized, and the operating system is loaded into the computer's memory.
There are two types of booting: cold booting (starting from a completely powered-off state) and warm booting (restart...

Technical interview round with questions based on DSA and OOPS.
Use double pointer to dynamically allocate memory for array of strings in C.
Declare a double pointer to hold the 2D array of strings.
Allocate memory for the rows first using malloc.
Then allocate memory for each string in the row using malloc.
Assign values to the strings in the array.
Example: char **array = malloc(rows * sizeof(char *));
Example: array[i] = malloc(strlen(str) + 1); strcpy(array[i], str);
Virtual functions in C++ are functions that can be overridden in derived classes, allowing for polymorphic behavior.
Virtual functions are declared using the 'virtual' keyword in the base class.
They are used to achieve runtime polymorphism in C++.
Derived classes can override the virtual functions defined in the base class.
Example: class Base { public: virtual void display() { cout << 'Base class dis...
Virtual base classes are classes that are inherited virtually to avoid multiple instances of the same base class in a derived class hierarchy.
Virtual base classes are used in multiple inheritance to prevent the Diamond Problem.
They are declared with the 'virtual' keyword in the base class.
When a class inherits a virtual base class, the most derived class is responsible for initializing the virtual base class.
Example: c...

Technical interview round with questions based on OS/Networking etc.
The system call that creates a separate connection is fork()
fork() is a system call in Unix-like operating systems that creates a new process by duplicating the existing process
The new process created by fork() is called the child process, while the original process is called the parent process
fork() is commonly used in network programming to create separate connections for handling multiple clients
epoll_wait() system call waits for events on an epoll instance
Used in Linux for I/O event notification
Blocks until one or more file descriptors become ready
Returns the number of file descriptors ready for I/O operations
Different protocols used in the transport layer include TCP, UDP, SCTP, and DCCP.
TCP (Transmission Control Protocol) - reliable, connection-oriented protocol used for most internet communication
UDP (User Datagram Protocol) - connectionless protocol used for applications where speed is more important than reliability
SCTP (Stream Control Transmission Protocol) - supports multiple streams of data, used for telecommunicati...
TCP is a connection-oriented protocol that ensures reliable data delivery, while UDP is a connectionless protocol that focuses on speed.
TCP is reliable and ensures data delivery by establishing a connection before sending data.
UDP is faster but less reliable as it does not establish a connection before sending data.
TCP is used for applications that require high reliability and error correction, such as web browsing and...

ICMP is a protocol used for error reporting, diagnostics, and network management in IP networks.
ICMP is used to report errors in packet delivery
It is used for network diagnostics and troubleshooting
ICMP messages are encapsulated within IP packets
Examples include ping (echo request/reply) and traceroute
TCP supports four types of connection release: active close, passive close, simultaneous close, and abortive close.
Active close: Client initiates the connection release process by sending a FIN packet.
Passive close: Server initiates the connection release process by sending a FIN packet.
Simultaneous close: Both client and server send FIN packets to each other simultaneously.
Abortive close: Connection is terminated abru...
The MAC layer uses protocols like CSMA/CA, CSMA/CD, and TDMA to manage access to the network.
CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) is used in wireless networks to avoid collisions.
CSMA/CD (Carrier Sense Multiple Access with Collision Detection) is used in wired networks to detect and handle collisions.
TDMA (Time Division Multiple Access) is used in networks where devices are assigned specific
ARP (Address Resolution Protocol) is a protocol used to map an IP address to a MAC address in a local network.
ARP is used to resolve IP addresses to MAC addresses in a local network.
It operates at the data link layer of the OSI model.
ARP requests are broadcasted to all devices on the network.
Example: When a device wants to communicate with another device on the same network, it uses ARP to find the MAC address correspo
