Doctroid Healthcare Interview Questions and Answers

A scheduler is a function that manages the execution of tasks or processes.

• Inputs: tasks or processes to be scheduled, priority or order of execution

• Output: schedule or order in which tasks or processes will be executed

• Functioning: determines the order of execution based on predefined criteria or algorithms

CQI plays a crucial role in downlink MCS selection.

• CQI stands for Channel Quality Indicator.

• It is a measurement of the quality of the wireless channel between the base station and the user equipment.

• Based on the CQI, the base station determines the appropriate modulation and coding scheme (MCS) for downlink transmission.

• Higher CQI values indicate better channel conditions and allow for higher MCS with higher data rates.

• Lower CQI values indicate poorer channel conditions and r...read more

SPS stands for Scheduling Policy Subsystem. It is responsible for managing the scheduling of processes in an operating system.

• SPS is a component of the operating system that handles process scheduling.

• It determines the order in which processes are executed on the CPU.

• SPS uses various scheduling algorithms to make decisions.

• Some common scheduling algorithms include First-Come, First-Served (FCFS), Round Robin, and Priority Scheduling.

• The scheduling mechanism of SPS involves ma...read more

Structs store data in a contiguous block of memory, while pointers store memory addresses.

• Structs store data in a sequential manner in memory

• Pointers store memory addresses of variables

• Example: struct Person { char name[20]; int age; }; Person p; int *ptr = &p.age;

The Ue attach procedure is a process in cellular networks where a user equipment (UE) establishes a connection with the network.

• The UE sends an attach request to the network.

• The network validates the request and assigns a temporary identifier to the UE.

• The network updates its location information for the UE.

• The network sends an attach accept message to the UE.

• The UE acknowledges the attach accept message.

• The network updates the UE's status as attached.

• The UE can now access ne...read more

Structure padding is the insertion of empty bytes between structure members to ensure proper alignment.

• Padding is added to align data types on memory boundaries for efficiency.

• It helps in optimizing memory access and improving performance.

• For example, a structure with int, char, and double members may have padding to align them properly.

RAT1 allocation is a process of assigning resources to a specific RAT1 (Radio Access Technology 1) network.

• RAT1 allocation involves assigning resources such as frequency bands, time slots, and channel codes to a specific RAT1 network.

• It is used in cellular networks to manage the allocation of resources for different radio access technologies.

• For example, in a LTE (Long-Term Evolution) network, RAT1 allocation determines how the available spectrum is divided between LTE and ot...read more
