Computers and Technology

1 answer:

V125BC [204]3 years ago

6 0

Answer:

Assuming that's in python, the answer would be 4

Explanation:

The ** operator is for raising a number to a power.

The // operator returns the number of times the right number can fit into the left (i.e round division).

So the answer would be three squared over two rounded down, or 4.

Describe the functions of ALU, resisters, CU, BIU, Cache and FPU.

stich3 [128]

Answer:

ALU :An arithmetic logic unit (ALU) is a digital circuit used to perform calculations and logic operations

Registers:register holds the address of memory where CPU wants to read or write data.

CU:The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor.

BIU:BIU takes care of all data and addresses transfers on the buses for the EU like sending addresses, fetching instructions from the memory, reading data from the ports and the memory as well as writing data to the ports and the memory.

Cache:Cache is used to temporarily hold instructions and data that the CPU is likely to reuse.

FPU:A floating-point unit (FPU, colloquially a math coprocessor) is a part of a computer system specially designed to carry out operations on floating-point numbers.

Suppose that the first goal in a GP problem is to make 3 X1 + 4 X2 approximately equal to 36. Using the deviational variables d1

Scrat [10]

Answer:

d. d1− = 10, d1+ = 0

Explanation:

Given

3X1 + 4X2 +d1− − d1+ = 36

X1 = 6

X2 = 2

Required

Possible values of d1- and d1+

We have:

3X1 + 4X2 +d1− − d1+ = 36

Substitute values for X1 and X2

3 *6 + 4 * 2 + d1- - d1+ = 36

18 + 8 + d1- - d1+ = 36

Collect like terms

d1- - d1+ = 36 - 18 - 8

d1- - d1+ = 10

For the above equation to be true, the following inequality must be true

d1- > d1+

Hence,

(d) is correct

Because:

10 > 0

Describe 6 difference of the types of computer<br>

Trava [24]

Answer:

<h3>1. Supercomputer</h3>

One of types of computers is supercomputer. It is a computer that is at the front-line of current processing capacity, particularly speed of calculation. It is usually used to do tasks involving intense numerical calculations such as weather forecasting, fluid dynamics, nuclear simulations, theoretical astrophysics, and complex scientific computations

<h3>2. Mainframe Computer</h3>

Another computer type is mainframe computer. It is a computer that is capable of handling and processing very large amounts of data quickly. Its calculation speed can reach millions to tens of millions instructions per second (MIPS) and it can respond to hundreds of millions of users at a time.

This computer type is mainly used in large institutions such as government, banks and large corporations.

<h3>3. Minicomputer (Mid-Range Computer)</h3>

Minicomputers are a class of multi-user computers that lie in the middle range of the computing spectrum, in between the smallest mainframe computers and the largest single-user systems (microcomputers or personal computers).

Minicomputers are usually small in scale, simple in structure, easy to maintain, and low in cost. Therefore, they are often used in universities, scientific research institutions and industrial control fields.

<h3>4. Microcomputer (Personal Computer)</h3>

The term “microcomputer” was introduced with the advent of systems based on single chip microprocessors. In the early days, the microcomputers would still have been too expensive to be owned by a single individual. But in the late 20th century, microcomputers became the most common type of computer.

Therefore, the term "microcomputer" has practically become an anachronism and has been replaced the term "personal computer (PC)".

Personal computer has developed rapidly because of its small size, convenient use, low production cost, and low price. PC computing speed can reach hundreds of thousands to millions instructions per second, which can meet the requirements of data processing and scientific computing in production, scientific research, and life.

<h3>5. Workstation Computer</h3>

A workstation computer is a high-end personal computer between microcomputers and minicomputers. It is usually equipped with large-capacity memory, external storage, and large-screen displays. Therefore, it has strong data processing capabilities and graphics processing capabilities.

Workstation computers are designed and developed mainly for professional application fields like engineering design, animation production, scientific research, software development, financial management, information services, analog simulation, etc.

<h3>6. Server Computer</h3>

A server refers to a high-performance computer that provides shared information resources and various services for many users on the network at the same time in a network environment.

A server is expected to be capable of high-speed computing, long-term reliable operation (it features error-correction of RAM; redundant cooling; self-monitoring, RAID), and powerful external data throughput.

The structure of the server is similar to that of an ordinary computer. Many smaller servers are actually personal computers that have been dedicated to provide services for other computers. But they are very different in terms of processing power, stability, reliability, security, scalability, and manageability.

According to the services provided, server computers can be subdivided into database server, file server, Web server, FTP server, etc.

A slide in Blake's presentation contained the following information:

deff fn [24]

Answer:

consistent phrasing is missing

Explanation:

If you will note carefully, the bullets are not in correct format. The model is missing. The correct one is as below.

Risks

The correct form of presentation is as below:

1. Risks

a. employees

a. physical illness

b. mental illness

c. death

2. Customers

a. complaints

b. downtime

3. Benefits

However, the content seems to be complete now, and hence not anything else is required. And since its not something very tough to decide to go with, bite the bullet is certainly not an issue.

A perfect binary tree is a complete binary tree with all levels fully filled. Add a method in the BST class to return true if th

algol [13]

Answer:

class BST {

static class Node

{

int val;

Node left, right;

}

static boolean checkPerfectBT(Node node, int h, int d)

{

if (node == null)

return true;

if (node.left == null && node.right == null)

{

if(h==d+1)

return true;

else

return false;

}

if (node.left == null || node.right== null)

return false;

return checkPerfectBT(node.left, h, d+1) && checkPerfectBT(node.right, h, d+1);

}

static int height(Node node)

{

int dep = 0;

while (node != null)

{

node = node.right;

dep=dep+1;

}

return dep;

}

static boolean isPerfectBT(Node node)

{

int h = height(node);

return checkPerfectBT(node, h, 0);

}

static Node addNode(int x)

{

Node node = new Node();

node.val= x;

node.right = null;

node.left = null;

return node;

}

public static void main(String args[])

{

int i,j,k;

Node node= null;

node = addNode(34);

node.left = addNode(2);

node.right = addNode(322);

node.left.left = addNode(21);

node.left.right = addNode(23);

node.right.left = addNode(37);

node.right.right = addNode(54);

if (isPerfectBT(node) == true)

System.out.println("This is a Perfect Binary tree");

else

System.out.println("This is Not a perfect Binary Tree");

}

Explanation:

Calculate the depth of BST by using a while loop until it reaches a null value.
In the addNode method, make an object of Node class.
In the main method, pass the values to addNode method.
Finally display the relevant message to show if it's Perfect or not.
