Foxconn Interview Questions and Answers
Q1. What is multicollinearity and what are its effects?
Multicollinearity is a phenomenon where two or more independent variables in a regression model are highly correlated.
It can lead to unstable and unreliable estimates of regression coefficients.
It can make it difficult to determine the individual effect of each independent variable on the dependent variable.
It can also result in inflated standard errors and p-values, making it difficult to identify statistically significant variables.
It can be detected using methods such as c...read more
Q2. Which language understand the computer?
Computers understand machine language, which is a set of binary codes representing instructions that the computer can execute.
Computers understand machine language, which consists of binary code representing instructions.
High-level programming languages like Python, Java, C++ are used to write code that is then translated into machine language.
Compilers and interpreters are used to convert high-level code into machine language for the computer to understand.
Q3. What is the advantage or lstm over rnn.
LSTM has better memory retention than RNN.
LSTM can remember long-term dependencies better than RNN.
LSTM has a gating mechanism that controls the flow of information.
LSTM can handle vanishing gradient problem better than RNN.
LSTM is more suitable for tasks that require long-term memory, such as speech recognition and language translation.
Q4. What does BIOS works for?
BIOS works as a firmware that initializes hardware components during the boot process of a computer.
BIOS stands for Basic Input/Output System
It is responsible for initializing and testing hardware components like the CPU, memory, and storage devices
BIOS also provides the necessary instructions for the operating system to boot up
It is stored on a ROM chip on the motherboard
Q5. What is the machine language?
Machine language is the lowest-level programming language that directly corresponds to instructions executed by a computer's CPU.
Machine language consists of binary code representing instructions that can be executed by a computer's central processing unit (CPU)
It is the lowest-level programming language and is specific to the type of CPU being used
Machine language is difficult for humans to read and write, as it is composed of strings of 0s and 1s

Q6. What is Ram? What is Rom?
RAM stands for Random Access Memory, a type of computer memory that can be accessed randomly. ROM stands for Read-Only Memory, a type of memory that stores data permanently.
RAM is volatile memory used by the computer to store data and program instructions temporarily.
ROM is non-volatile memory that stores firmware and cannot be easily modified or deleted.
RAM is faster but loses data when power is turned off, while ROM is slower but retains data even when power is off.
Q7. what is indexing
Indexing is a technique used to optimize the performance of databases by creating a data structure that allows for quick retrieval of data.
Indexing involves creating a data structure that maps the values of a particular column in a database table to their physical storage locations on disk.
It helps in speeding up data retrieval operations by allowing the database to quickly locate the rows that satisfy a certain condition without having to scan the entire table.
