Computer store digital data, while telephone lines can only transfer analog data. If a computer is to be connected to internet through telephone, then it must convert digital data to analog data before transmitting the computer signals.
Converting one signal form to another form is called modulation and reconverting it to original form is called as demodulation.
Modern is modulator/demodulator. Modem is used to connect computer to internet. Modems convert digital data to analog data and vice-a-versa.

What do you mean by looping? Explain different types of loop in PHP

Posted by Aryan Kanwar 4 years, 3 months ago

CBSE > Class 12 > Computer Science

1 answers

Yogita Ingle 4 years, 3 months ago

A loop is a statement that repeats over and over, while a certain condition is true. Or, to state it another way, it runs until a condition is false. A condition is the value or state you are testing. For example, if you want to repeat the same math program 50,000 times, you can write a loop that runs until it has processed 50,000 times.

Loops in PHP are used to execute the same block of code a specified number of times. PHP supports following four loop types.

for − loops through a block of code a specified number of times.
while − loops through a block of code if and as long as a specified condition is true.
do...while − loops through a block of code once, and then repeats the loop as long as a special condition is true.
foreach − loops through a block of code for each element in an array.

In computer science, a library is a collection of non-volatile resources used by computer programs, often for software development. These may include configuration data, documentation, help data, message templates, pre-written code and subroutines, classes, values or type specifications.

In computer programming, a library refers to a collection of files, programs, routines, scripts, or functions that can be referenced in the programming code.

What are rhe four data type in python

Posted by Rahul Saini 4 years, 3 months ago

CBSE > Class 12 > Computer Science

1 answers

Gaurav Seth 4 years, 3 months ago

Python has the following standard or built-in data types:

Numeric

A numeric value is any representation of data which has a numeric value. Python identifies three types of numbers:

Integer: Positive or negative whole numbers (without a fractional part)
Float: Any real number with a floating point representation in which a fractional component is denoted by a decimal symbol or scientific notation
Complex number: A number with a real and imaginary component represented as x+yj. x and y are floats and j is -1(square root of -1 called an imaginary number)

Boolean

Data with one of two built-in values <code>True</code> or <code>False</code>. Notice that 'T' and 'F' are capital. <code>true</code> and <code>false</code> are not valid booleans and Python will throw an error for them.

Sequence Type

A sequence is an ordered collection of similar or different data types. Python has the following built-in sequence data types:

String: A string value is a collection of one or more characters put in single, double or triple quotes.
List : A list object is an ordered collection of one or more data items, not necessarily of the same type, put in square brackets.
Tuple: A Tuple object is an ordered collection of one or more data items, not necessarily of the same type, put in parentheses.

Dictionary

A dictionary object is an unordered collection of data in a key:value pair form. A collection of such pairs is enclosed in curly brackets. For example: <code>{1:"Steve", 2:"Bill", 3:"Ram", 4: "Farha"}</code>

type() function

Python has an in-built function type() to ascertain the data type of a certain value. For example, enter <code>type(1234)</code> in Python shell and it will return <code><class 'int'></code>, which means 1234 is an integer value. Try and verify the data type of different values in Python shell, as shown below.
