A web _____________ is software that finds websites, webpages, images, videos, news, maps and other information related to a specific topic.

Answer:

a. The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.

b. 195.200.0.0/22

Explanation:

195.200.0.0/16

The number of bits to give 512 is 9

2^9=512

2^8=256 which is not up to our expected 320 customers that requires a network ip

Note we have to use a bit number that is equal or higher than our required number of networks.

The number of host per each subnet of the network (195.200.0.0/25) is (2^7)-2= 128-2=126

The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.

b. 64 customers requires  6 bits to be taken from the host bit to the network bit

i.e 2^6 = 64

195.200.0.0/22

The number of host per each subnet of the network (195.200.0.0/22) is (2^10)-2=1024 - 2 = 1022 hosts per subnet

This network meet the requirement " 64 customers want 128 addresses/customer "

Answer:

no events will be returned

Explanation:

Answer:

public class Main

{

public static void main(String[] args) {

    int time = 60;

    --time;

    System.out.println(time);

}

}

Explanation:

*The code is in Java.

Initialize an integer called time and set it to some value, in this case 60

To use the decrement operator in prefix mode, you need to write the decrement operator, --, before the variable time. The decrement operator decreases the variable value by one first and then gives back the new value. In our example the output will be 59.

3 = 0011

B = 1011

E = 1110

8 = 1000

C = 1100

D = 1101

A = 1010

Put together, 00-FF-03-BE-8C-DA becomes;

00000000 11111111 00000011 10111110 10001100 11011010

Answer:

According to section 40-15-102(18) of the Colorado Revised Statutes (CRS), a residential “Residential subscriber” is an individual who has elected to receive residential telephone service with a local exchange provider. The definition of “Person” here is extended to include any other persons living or residing with the residential subscriber.

A rate center is a geographical area used to define and organise the perimeter for local calling, for billing, and for assigning specific phone numbers, which can include multiple area codes.

The rate center boundaries are determined by Local Exchange Carriers (LEC)

LEC is just a regulatory jargon in the telecoms sector for the local telephone company.

A wire center is the actual physical telephone exchange building.

A rate center, on the other hand, is a regulatory concept designed with the primary goal to make billing administration within the local telephone serving area easy.

The Recovery Point Objective tells how old a backup file must be before it can be  recovered by a system after failure.

Since the data in the failover systems described in this question must be backup and recovered after the failure, it will be important to include the Recovery Point Objective (RPO) in the Business Continuity Plan.

Since the failover systems must use back up data that is no older than one hour, the backup of the system data must be done at intervals of 60 minutes or less. Meaning that the maximum RPO is 60 minutes.

Note that RPO is more critical than RTO in data backup

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

Answer / Explanation:

195.200.0.0/16

Note: Class C address can not be assigned a subnet mask of /16 because class c address has 24 bits assigned for network part.

2ⁿ = number of subnets

where n is additional bits borrowed from the host portion.

2ˣ - 2 = number of hosts

where x represent bits for the host portion.

Assuming we have 195.200.0.0/25

In the last octet, we have one bit for the network

number of subnets  = 2¹  =2 network addresses  

number of host = 2⁷ - 2= 126 network addresses per subnets

Answer:

B

Explanation:

Here, we want to calculate the storage capacity of the disk drive.

We proceed as follows;

Per track capacity = 4 * 256 KB = 1024 KB = 1 MB

per platter capacity = 1 MB * 8192 = 8192 MB

total capacity = 16 * 8192 MB = 131072 MB

converting total capacity to GB,

1024 MB = 1 GB

thus, 131,072 MB to GB would be;

total capacity =131072/1024 = 128GB

Regression test

Explanation:

There are different types of testing in software development. Some of them are;

i. Smoke test

ii. Interface test

iii. Alpha test

iv. Beta/Acceptance test

v. Regression test

vi. System test

While all of these have their individual meanings and purposes, the regression test seeks to confirm that a recent update, modification or change in the underlying program code of the application (software) has not affected the existing features. This test ensures that a change to a software has not introduced new bugs or vulnerabilities to the state of the software before the change was made.

Regression test is actually done when;

i. there is a change in requirements of the software and thus the code is modified.

ii. a new feature is added to the software.

Answer:

I am writing a Python program:

import re

def NonOverlapping():

   string = input("Enter a string: ")

   substring = input("Enter a substring to find its non-overlapping occurances in " + string +": ")

   occurrences=len(re.findall(substring,string))

   return occurrences

print("The number of non-overlapping occurrences: " , NonOverlapping())

Explanation:

I will explain the program line by line.

import re  this is the module for performing regular expressions matching operations in Python.

def NonOverlapping(): this is the function definition. The function name is NonOverlapping and this function returns the number of non-overlapping occurrences of a substring in a string.

string = input("Enter a string: ")

substring = input("Enter a substring to find its non-overlapping occurances in " + string +": ")

The above two statement ares used to take input from the user. First the user is prompted to enter a string and the string is stored in string variable. Next user is asked to input the substring and its stored in susbtring variable.

occurrences=len(re.findall(substring,string)) This is the main line of the function. It has two methods i.e. len() and re.findall().

The re.findall() method returns all non-overlapping matches of substring in string. The string is checked for the given substring from left to right and all the non-overlapping occurrences of the substring are found and a list of matches is returned. len() method is used to return the length of the string but here it is used to count the number of non-overlapping occurrences substring in a string which are returned by re.findall() method. The whole result of these two methods is stored in occurrences.

return occurrences  This statement returns the number of non-overlapping occurrences of a substring in a string computed in the above statement.

print("The number of non-overlapping occurrences: " , NonOverlapping())

This statement displays the result by calling NonOveralling() method.

Answer:

Both manual and digital editing are concepts used in proofreading.

Manual editing is also called "hard proofreading" (or "hard proofing" for short). It is the process of proofreading, modifying or revising printed documents. In this type of proofreading, one would normally manually mark parts of the printed documents with editing materials such as ink, pen, marker e.t.c

Digital editing is also called "soft proofing". In contrast to manual editing, this type is done on digital documents. These documents include, but not limited to, DOC, txt, PDF, image, audio and video files.

Tools for editing manually are;

i. pen

ii. ink

iii. tipex

Tools for editing digitally are;

i. Photoshop application

ii. Text editors such as notepad++, Microsoft word

Proofreading has evolved in recent times as a result of advancements in technology. Now, manual proofreading has paved way for digital proofreading, which allows revising of PDF and  DOC files. The difference in both forms is as follows:

Manual Editing: In the process of revising or proofing printed documents, one would manually apply standard proofreading marks. Manual editing is also known as "Hard proofing", as the process requires proofreaders to mark the hard copies.

Digital Editing: In the process of revising or proofing digital documents i.e. PDF and DOC files, one would digitally apply the proofreading marks. Thus, corrections and edits are transferred electronically among authors, proofreaders. Digital editing is also known as "Soft proofing", as the process requires proofreaders to mark the soft copies i.e. without using any paper or pen.

There are a number of electronic tools and marks available for both techniques of

proofreading. Some tools used for manual proofreading include- deletion, capitalization, and  insertion, close-up, transpose.

Tools used in digital proofreading include- spell check, readability levels, trite expressions,  and comment, track changes.
