BWP part concept refers to the concept of breaking down a software system into smaller, more manageable parts.

• BWP stands for Break-When-Problematic

• It helps in identifying and isolating issues in the system

• Each part should have a clear responsibility and interface with other parts

Corset is a tight-fitting undergarment worn to shape and support the torso.

• Corsets were popular in the Victorian era.

• They were worn by women to achieve an hourglass figure.

• Modern corsets are often used as fashion statements or for waist training.

• Corsets can be made of various materials such as satin, leather, or lace.

• They can be fastened with laces, hooks, or zippers.

UE attach procedure is a process in LTE network where a UE establishes a connection with the network.

• UE sends RRC Connection Request message to eNodeB

• eNodeB sends RRC Connection Setup message to UE

• UE sends RRC Connection Setup Complete message to eNodeB

• eNodeB sends RRC Connection Reconfiguration message to UE

• UE sends RRC Connection Reconfiguration Complete message to eNodeB

• UE is now attached to the network

I am not using any numerology in my work as a Senior Software Engineer.

• I do not believe in numerology and do not use it in my work.

• My focus is on writing efficient and effective code.

• Numerology has no place in software engineering.

RB's bandwidth usage depends on the specific product and its features.

• RB's have different bandwidth usage depending on the product

• The bandwidth usage also depends on the features of the product

• Examples of RB's with different bandwidth usage are RB750Gr3 and RB4011iGS+RM

CCE stands for Continuous and Comprehensive Evaluation.

• CCE is a system of evaluation in education that assesses students' progress continuously throughout the year.

• It is a comprehensive approach that takes into account various aspects of a student's development, including academic, social, and emotional.

• CCE aims to reduce the emphasis on rote learning and promote a more holistic approach to education.

To find a loop in a linked list, use Floyd's cycle-finding algorithm.

• Use two pointers, one moving at a rate of one node per iteration and the other moving at a rate of two nodes per iteration.

• If there is a loop, the two pointers will eventually meet at the same node.

• If there is no loop, the faster pointer will reach the end of the list.

• Time complexity: O(n), Space complexity: O(1)

WAP set bit or reset bit is a programming concept used to manipulate individual bits in a binary number.

• Setting a bit involves changing its value from 0 to 1.

• Resetting a bit involves changing its value from 1 to 0.

• This concept is commonly used in low-level programming and hardware manipulation.

• Example: Setting the 3rd bit of a binary number 1010 would result in 1110.

• Example: Resetting the 2nd bit of a binary number 110...read more

Semaphore is a synchronization object used to control access to a shared resource.

• Semaphore is a signaling mechanism used to control access to a shared resource

• It maintains a count of available resources and blocks the thread if the count is zero

• Semaphore can be used to implement critical sections, mutexes, and barriers

• Examples include controlling access to a database or limiting the number of concurrent connections

Arrays are faster for random access, while linked lists are better for frequent insertions and deletions.

• Arrays have a fixed size, while linked lists can grow dynamically.

• Arrays are stored in contiguous memory, while linked lists use pointers to connect nodes.

• Accessing an element in an array is O(1), while in a linked list it is O(n).

• Inserting or deleting an element in an array is O(n), while in a linked list it is O(1...read more

The command used for taking Wireshark logs is 'tcpdump'.

• Wireshark is a network protocol analyzer tool

• Tcpdump is a command-line tool used to capture network traffic

• Tcpdump can be used to capture packets and save them as a file for analysis in Wireshark

• Example command: tcpdump -i eth0 -w capture.pcap

Use command line tools like 'ps' or 'top' to find the number of running processes on a server.

• Use 'ps aux' command to list all running processes and count the number of lines

• Use 'top' command and look for the 'Tasks' section which shows the number of running processes

• Use 'htop' command which provides a more interactive and detailed view of running processes
