NAT stands for Network Address Translation. It is a process of translating IP addresses between different networks.

• NAT allows multiple devices in a private network to share a single public IP address.

• It provides security by hiding the internal IP addresses from external networks.

• NAT enables the conservation of public IP addresses by allowing multiple devices to use a single IP.

• It facilitates the routing of traffic betw...read more

VLAN stands for Virtual Local Area Network. It is a technology that allows the creation of multiple virtual networks within a single physical network.

• They enable easier network management and troubleshooting.

• VLANs are commonl...read more

Client and server establish communication through sockets. Creating a socket involves several steps.

• Client and server each create a socket object.

• Server socket binds to a specific port number on the server machine.

• Server socket listens for incoming client connections.

• Client socket connects to the server socket using the server's IP address and port number.

• Once the connection is established, client and server can exchan

A socket buffer is a data structure used by the operating system to store data being sent or received over a network socket.

• Socket buffers are typically implemented as circular buffers.

• They are used to temporarily hold data until it can be processed by the application.

• Socket buffers have a fixed size and can be filled or emptied by the operating system or the application.

• They help in managing the flow of data between t...read more

A bridge is a structure that connects two separate areas, allowing for the passage of people, vehicles, or other forms of transportation.

• Bridges provide a means of crossing obstacles such as rivers, valleys, or roads.

• They facilitate the movement of people, vehicles, and goods from one place to another.

• Bridges can be made of various materials such as concrete, steel, or wood.

• They can be designed in different styles and ...read more

IPC is a mechanism for communication between processes, while ITC is for communication between threads within a process.

• IPC allows processes to exchange data and synchronize their actions.

• ITC allows threads to share data and coordinate their activities.

• IPC can be implemented using various techniques such as pipes, sockets, shared memory, and message queues.

• ITC can be achieved through shared variables, message passing, ...read more

I come from a diverse family background and have achieved success in my career through hard work and dedication.

• I come from a family with a mix of different cultures and traditions.

• I have excelled in my career by consistently delivering results and taking on new challenges.

Linking is the process of connecting different web pages or resources together through hyperlinks.

• Linking is an essential aspect of the World Wide Web.

• It allows users to navigate between different web pages by clicking on hyperlinks.

• Hyperlinks can be text, images, or other elements that when clicked, direct the user to another web page or resource.

• Linking helps in organizing and structuring information on the web.

• It en...read more

Little endian and big endian are byte ordering formats. Little endian stores the least significant byte first, while big endian stores the most significant byte first.

• Little endian and big endian refer to the order in which bytes are stored in memory.

• In little endian, the least significant byte is stored first, followed by the more significant bytes.

• In big endian, the most significant byte is stored first, followed by ...read more

Different types of memory segments include code segment, data segment, stack segment, and heap segment.

• Code segment stores the executable code of the program.

• Data segment stores global and static variables.

• Stack segment stores local variables and function call information.

• Heap segment stores dynamically allocated memory.

• Example: In C programming, global variables are stored in the data segment.

Zombie, daemon, and orphan processes are different types of processes in operating systems.

• Zombie processes are dead processes that have completed execution but still have an entry in the process table.

• Daemon processes are background processes that run continuously and perform specific tasks.

• Orphan processes are child processes that continue to run even after their parent process has terminated.

• Zombie processes consume...read more

To create parent and child processes, use fork() system call. To create threads, use pthread_create() function.

• To create a child process, use fork() system call. The child process is an exact copy of the parent process.

• To create threads, use pthread_create() function from pthread library.

• Parent and child processes can communicate using inter-process communication mechanisms like pipes or shared memory.

• Threads share the...read more

The common segments used by parent and child processes are code segment, data segment, and stack segment.

• Code segment: Contains the executable code of the program.

• Data segment: Stores global and static variables.

• Stack segment: Used for local variables and function calls.

The common segments used by threads are code segment, data segment, and stack segment.

• Code segment: Contains the executable code of the program.

• Data segment: Stores global and static variables.

• Stack segment: Used for local variables and function call information.

A symbol table is a data structure used by compilers and interpreters to store information about the variables, functions, and other symbols in a program.

• It maps each symbol to its attributes, such as its data type, memory location, and scope.

• Symbol tables are used during the compilation or interpretation process to resolve references to symbols and perform semantic analysis.

• They enable efficient lookup and retrieval o...read more

gcc is a command-line compiler used to compile programs written in C or C++.

• To compile a program using gcc, use the command 'gcc -o '.

• The '-o' option is used to specify the name of the output file.

• By default, gcc compiles C programs. To compile C++ programs, use the '-x' option followed by 'c++'.

• To enable warnings during compilation, use the '-Wall' option.

• To optimize the compiled code, use the '-O' opt...read more
