A hard disk has four surfaces (that's top and bottom of two platters). Each track has 2,048 sectors and there are 131,072 (217)

tracks per surface. A block holds 512 bytes. The disk is not "zoned." What is the total capacity of this disk

Answer:

128 GB

Explanation:

Here, we are interested in calculating the total capacity of the disk.

From the question, we can identify the following;

Number of surfaces = 4

Tracks per surface = 131,072

Number of sectors = 2,048

Each Block size = 512 bytes

Mathematically;

Total data capacity of the disk = no of tracks * no of sectors * block size

= 131,072 * 2048 * 512 bytes

= 2^17 * 2^11 * 2^9 bytes = 2^37 bytes

1 GB = 2^30 bytes

So 2^37 = 2^7 * 2^30

= 128 GB

In which type of referencing do you get a warning message? Explain why.​
Art [367]

Answer:

These are the problems that are not severe enough to prevent processing. They mainly complain about the previous version of your document. In the case of command invalid, the latex gives a warning and henceforth it needs to be fixed.

Explanation:

There are some bugs in which they are not that severe that make the system not process.. but they are still mistakes in which might affect how the program run those parts.. like in JavaScript in the program i use, the minor bugs are like symbolized as yellow triangle and they are normally like signalizing a grammar error in the code and the app still runs but just that part of the code is invalid or reads wrong.. while big errors like codes that dont make sense, those make a red squareish that as soon as you try to run the program the debug console states in all red "Line 50(or whatever line) SyntaxError" or other things

Describe the third generation of computers​
djverab [1.8K]

Answer:

The period of third generation was from 1965-1971. The computers of third generation used Integrated Circuits (ICs) in place of transistors. A single IC has many transistors, resistors, and capacitors along with the associated circuitry.

The IC was invented by Jack Kilby. This development made computers smaller in size, reliable, and efficient. In this generation remote processing, time-sharing, multiprogramming operating system were used. High-level languages (FORTRAN-II TO IV, COBOL, PASCAL PL/1, BASIC, ALGOL-68 etc.) were used during this generation.

Third Generation

The main features of third generation are −

IC used

More reliable in comparison to previous two generations

Smaller size

Generated less heat

Faster

Lesser maintenance

Costly

AC required

Consumed lesser electricity

Supported high-level language

Some computers of this generation were −

IBM-360 series

Honeywell-6000 series

PDP (Personal Data Processor)

IBM-370/168

TDC-316

Analyze the following code. public class Test { public static void main(String[] args) { double radius; final double PI= 3.15169
sergiy2304 [10]

Answer:

The output of the given code as follows:

Output:

Area is: 12.60676

Explanation:

In the given code some information is missing so, the correct code to this question can be described as follows:

Program:

public class Test //defining class  

{

   public static void main(String[] args)//defining the main method

   {

       double radius= 2; //defining double variable radius

       final double PI= 3.15169; //defining double variable PI

       double area = radius * radius * PI; //defining double variable area that calculates values

       System.out.println("Area is: " + area); //print values

   }  

}

Explanation:

  • In the given java code a class "Test" is defined, in which a double variable "radius" is defined, which holds a value, that is 2.
  • In the next step, a double constant variable, that is PI is defined, that holds a value, that is "3.15169".
  • Then another double variable area is defined, that calculates the area value, and prints its value.
