Introduction to Computer

Computers are the machines that can perform tasks or calculations according to set of instructions or programs. The term computer is derived from the word compute which means to calculate. Computer is an electronic device that can perform arithmetic and logical calculations faster. The first fully electronic computers, introduced in 1940s, were huge machines that required teams of people to operate. Compared to those early machines, today's computers are not only thousand times faster, they can fit on your desk, lap and even pocket. You must appreciate the impact of computer in our day-to-day life. The computer has been useful in reservation of tickets in Airlines and Railways, payment of telephone and electricity bills, deposits etc.

Advantages of computer

Computers are very fast due to which thousands of job can be performed within a short period of time.

Complex mathematical problems and logical operations can be solved by using this computer.

As computer is a versatile device, multiple task like communication, graphics, documentation can be done.

A huge amount of data can be stored and retrieved as it has high storage capacity.

Disadvantages of computer

Computers are machine hence, they have no brain so they work according to the program instructions set inside it.

It is an electronic device and it uses electrical sources to work, so it is very risky to store data and information on the computer independently because some electrical and electronic damages may damage the data. So we have to make regular backup of the data.

Since computers are very expensive device, it becomes beyond the capacity of general user. But now a day its price is going down than past.

Computers require dustless and temperature maintained environment for best performance

Write a function silence (typecode, length) that returns a new data array containing all zeros of the given type code and length

lions [1.4K]

Answer:

Following are the code to this question:

import array as a#import package array

def silence(typecode, length):#defining method silence that accepts two parameters

Val= a.array(typecode, [0]*length)#defining Val variable that stores zeros of the given type code and length

return Val# use return keyword for return Val variable value

typecode = input('Enter typecode value: ')#use input method for input

length = int(input('Enter length value: '))#defining length variable that input integer value

print(*(silence(typecode, length)))#use print method to call silence method

Output:

Enter typecode value: b

Enter length value: 10

0 0 0 0 0 0 0 0 0 0

Explanation:

description of the code:

In the above-given Python code, Firstly we import a package that is the array, after that a method "silence" is defined that accepts two variables in its parameter that is "typecode and length".
Inside the method, the "Val" variable is declared, which is used to calculate and store all zeros of the typecode and length variable.
Outside the method, "typecode and length variable" is used for input the value from the user end-use the print method to call the function "silence" with an asterisk.

What is the output of this code sequence? (Be exact in your answer with spacing) double [] a = {12.5, 48.3, 65.0}; System.out.pr

kolbaska11 [484]

Answer:

48.3

Explanation:

double [] a = {12.5, 48.3, 65.0}; This line creates the array a, which has three values, those three values can be accesed with the index operator, [].

System.out.println(a[1]); This line prints in the console the value in the array a in the second position, in Java the index inside arrays starts from zero, then puts a new line.
