Expressions provide an easy way to perform operations on data values to produce other data values, True.

<h3>What is an Expression? </h3>

An expression is a combination of one or more operands (Constant, Variable, Array element, Function), operators(Multiplication,Division, Subtraction etc) to be interpreted by a programming language following rules of precedence or association to produce other data values.

Three kinds of expressions includes:

An arithmetic expression

A character expression

A logical or relational expression

Therefore, it is true that Expressions provide an easy way to perform operations on data values to produce other data values.

OS(The Operating System) sends interrupts to the processor to stop whatever is being processing at that moment and computer architecture send data bus. This bus sends data between the processor,the memory and the input/output unit.

The operating system is a low-level software that supports a computer’s basic functions, such as scheduling tasks and controlling peripherals while the computer architecture has the address bus bar. This bus carries signals related to addresses between the processor and the memory.

The interface between a computer’s hardware and its software is its Architecture while An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.

Explanation:

In short explanation,the Computer Architecture specifically deals with whatever that's going on in the hardware part of the computer system while the Operating System is the computer program which has been program to execute at some instances depending on the programming instructions embedded in it. An example is the MS Office.

You trained a binary classifier model which gives very high accuracy on thetraining data, but much lower accuracy on validation

kompoz [17]

Answer:

a. This is an instance of overfitting.

Explanation:

In data modeling and machine learning practice, data modeling begins with model training whereby the training data is used to train and fit a prediction model. When a trained model performs well on training data and has low accuracy on the test data, then we say say the model is overfitting. This means that the model is memorizing rather Than learning and hence, model fits the data too well, hence, making the model unable to perform well on the test or validation set. A model which underfits will fail to perform well on both the training and validation set.
