Answer:
integrated
Explanation:
Due to this compatibility, we describe database data as integrated. This is because data integration refers to the process of combining data from different sources into a single, and unified view/database. This creates a large gathering of various information that can all be interswapped and used with the same software as one another.
You are an ISP. For the Address Block 195.200.0.0/16 a. If you have 320 Customers that need 128 addresses/customer - will there be enough addresses to satisfy them? and explain why? b. Say the first block of 64 customers want 128 addresses/customer - what would the address space look like?
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 "

hard disk drive has 16 platters, 8192 cylinders, and 256 4KB sectors per track. The storage capacity of this disk drive is at most Select one: a. 32 GB. b. 128 GB. c. 128 TB. d. 32 TB.
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
Constructing a concurrent server by spawning a process has some advantages and disadvantages compared to multithreaded servers. Discuss a few.
Answer:
The advantage and the disadvantage of the relevant query are illustrated in the explanation in the paragraph below.
Explanation:
Advantage:
The benefit of creating a simultaneous server through spawning a mechanism seems to be that alternative methods are shielded against everyone else, which would be very necessary whenever the extremely database manages communication services entirely.Disadvantage:
The downside about creating a concurrent system through spawning a methodology seems to be that this process seems to be very expensive but using multicore processing systems should save this expense. It is also easier when using threads again for the aim of communicating between two or even more participants although we stop the kernel executing the correspondence.Select the correct answer.

Write a statement that uses the decrement operator, in prefix mode, to decrease the value of the variable time.
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.
Suppose you are provided with 2 strings to your program. Your task is to join the strings together so you get a single string with a space between the 2 original strings. This is a common case is coding and you will need to create your output by joining the inputs and adding the space in the middle.
# Input from the command line
import sys
string1 = sys.argv[1]
string2 = sys.argv[2]
Answer:
public class TestImport{
public static void main(String[] args) {
String string1 = args[1];
String string2 = args[2];
System.out.println(string1 +" " +string2);
}
}
Explanation:
The solution here is to use string concatenation as has been used in this statement System.out.println(string1 +" " +string2);
When this code is run from the command line and passed atleast three command line arguments for index 0,1,2 respectively, the print statment will return the second string (that is index1) and the third argument(that is index2) with a space in-between the two string.

A. A maximum MTTR of 30 minutes
B. A maximum MTBF of 30 minutes
C. A maximum RTO of 60 minutes
D. An SLA guarantee of 60 minutes
Answer:
D. A maximum RPO of 60 minutes
Explanation:
Note that an option is not included in this list of options.
The complete list of options is:
A. A maximum MTTR of 30 minutes
B. A maximum MTBF of 30 minutes
C. A maximum RTO of 60 minutes
D. A maximum RPO of 60 minutes
E. An SLA guarantee of 60 minutes
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

The attack in which the attacker sends a fragmented message that the victim cannot reconstruct is a(n) ________ attack.
Answer:A teardrop attack
Explanation:
A teardrop attack also called denial-of-service attack is one which an attacker, usually a hacker sends many fragmented bug data messages to a victim's machine causing a crash in the device. This is because data moves in small data packets of whose transmission should follow layers according to the model of the devise be it OSI or TCP/IP model. Now when a hacker continually sends huge amounts of packets of bug data, the process of data transmission fails and packet data becomes overlapped, making the victim 's device machine in disarray and difficult to reconstruct while trying to rearrange them. When the hacker continually sends in more bug data packets to the already confused machine, The machine system crashes.
For the Address Block 195.200.0.0/16 a. If you have 320 Customers that need 128 addresses/customer - will there be enough addresses to satisfy them? and explain why? b. Say the first block of 64 customers want 128 addresses/customer - what would the address space look like?
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

1. Supply chain planning system.
2. Supply chain execution system.
In this case, supply chain execution system manages the flow of products through distribution centers and warehouses to ensure that products are delivered to the right locations in the most efficient manner. There are various types of supply chain execution systems, these include;
1. Order fulfillment management system software.
2. Transport management system software.
3. Global trade management system software.
4. Warehouse management system software.
Hence, a supply chain execution system if effectively and efficiently used can be used to enhance final production, reverse distribution, distribution management, commitments, and replenishment.
What are the differences between editing manually and editing digitally? What tools are used for each?
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.

B | 11 | 1011
C | 12 | 1100
D | 13 | 1101
E | 14 | 1110
F | 15 | 1111
Now, from the table;
0 = 0000
0 = 0000
F = 1111
F = 1111
0 = 0000
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

What is the difference between requirements and controls in the security process? Give examples of each.
Answer:
Security controls are those measures taken to prevent, identify, counteract, and reduce security risks to computer systems, whereas, Security Requirements are guidelines or frameworks that stipulates measures to ensure security control.
Explanation:
Security controls encompass all the proactive measures taken to prevent a breach of the computer system by attackers. Security requirements are those security principles that need to be attained by a system before it can be certified as safe to use.
Security controls are of three types namely, management, operational, and technical controls. Examples of technical controls are firewalls and user authentication systems. A statement like 'The system shall apply load balancing', is a security requirement with an emphasis on availability.
The common channel signaling (CCS) system provides a separate network dedicated to control and signaling over the PSTN. This enables subscribers to establish calls on an on-demand basis.
A. True
B. False
Common Channel Signaling (CCS) is a type of signaling used in multichannel communications systems to control, account for, and manage traffic on all the channels of a link. User information is not sent over the common-channel signaling channel.
What CCS system provides a separate network?Digital communication signaling takes the form of channel-associated signaling (CAS), often referred to as per-trunk signaling (PTS).
It uses routing information, like the majority of telecommunication signaling techniques, to send the voice or data payload to the intended recipient.
The SMS effectively serves as the CAS's administration hub. It is a hardware and software combination that is integrated with the CAS server. Each subscriber's information, including the TV stations they have chosen to subscribe to, is stored and managed via SMS.
Therefore, it is true that (CCS) is a type of signaling where a collection of speech and data channels share an exclusive channel for control signals.

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

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.
Problem You Need to Solve for This Lab:
You are asked to write an app to keep track of a relatively small music library. The app should load song information from a data file once the app is started. It should allow user to view, add, remove, and search for songs. The app should save the data back to the same data file when the program exits.
What Your Program Should Do:
Write an interactive text based menu interface (using a loop) that will allow the user to
ï‚· Enter information for a new song
ï‚· Display information for all the songs in the database with index for each song
ï‚· Remove a song by index
ï‚· Search for songs by a certain artist
ï‚· Search for songs by a certain album
ï‚· Quit
For each song, you need to keep track of:
title
artist
duration
album
Allow the program to keep looping until user wants to quit. When the program starts, it should load the tasks from external file ("songs.txt") into memory. When user enters information about the new song, the program needs to read them in, save them in memory and eventually write them to the external data file ("songs.txt"). The file format could look like:
Stereo Hearts;Gym Class Heroes;3;34;The Papercut Chronicles II
Counting Stars;OneRepulic;4;17;Native
The ';' is used as a delimiter or field separator. Each record ends with a new line character.
Some Implementation Requirements:
Write at least four functions WITH arguments for this assignment.
Use struct named Song to model each song
Use array of structs to model the collection of songs.
Hint: In this assignment, some data fields may have multiple words in it. Therefore,
you now SHOULD read using the 3 argument version of get.
Watch out. When using the 3 argument version of get you need to make sure to
remove the delimiter or newline. Therefore, anytime you read (even a confirmation
message), make sure to eat the newline using cin.ignore(...)!
Make sure to have a delimiter written between each item in the file – like a newline.
This will be important when you read the information back from the file.
For submission, your data file should contain a sufficient set of test data. It should have test cases for same artist with multiple songs and same album with multiple songs in it.
Do-Not List:
No Global Variables (you can have global constants)
Do not use Classes or Linked Lists
You must use cstring and char arrays. (do not use )
No use of the stdio library (use iostream and fstream)
Instead of the string class, you will be using arrays of characters and the cstring library
No STL containers such as vector. You must implement your own array for this class.
