Answer:
b. In HTTP tunneling, some protocols travel inside HTTP traffic.
Explanation:
a. HTTP is not a stateful protocol. It is a stateless protocol since the receiver is not allowed to store the state from previous requests. In other words, there is no need to keep track of the session information or status. Other examples of stateless protocol are UDP (User Datagram Protocol) and DNS (Domain Name System).
b. In HTTP tunneling, some protocols travel inside HTTP traffic. HTTP tunneling allows two devices to be connected together using network link with or without restrictions such as firewalls and access control lists. One way of implementing this HTTP tunneling is by using the regular HTTP methods such as POST, GET, PUT and DELETE.
In other words, HTTP tunneling allows certain protocols travel inside HTTP traffic.
c. HTTP has not been replaced with IPV6. They are different protocols performing different functions. IPV6 is an internet protocol addressing scheme invented to replace its predecessor IPV4.
d. HTTP was not developed by AI Gore. It was developed by Tim Berners-Lee and his team.

(d) convert(37)₁₀= ( )₂ ?
Answer:(a) (101011)₂ = ( 43)₁₀
(b) (596)₁₀= ( 254)₁₆
(c) ( 101011101)₂ = ( 15D)₁₆
(d) (37)₁₀= ( 100101)₂
Explanation:(a) convert (101011)₂ = ( )₁₀
This means that (101011)₂ be converted to base 10 (decimal).
To convert from binary to decimal, find the sum of the binary digits times their power of 2. i.e
(101011)₂ = 1 x 2⁵ + 0 x 2⁴ + 1 x 2³ + 0 x 2² + 1 x 2¹ + 1 x 2⁰
(101011)₂ = 1 x 32 + 0 x 16 + 1 x 8 + 0 x 4 + 1 x 2 + 1 x 1
(101011)₂ = 32 + 0 + 8 + 0 + 2 + 1
(101011)₂ = 43₁₀
Therefore, (101011)₂ = ( 43)₁₀
(b) convert(596)₁₀= ( )₁₆
This means that (596)₁₀ be converted to base 16 (hexadecimal).
To convert from decimal to hexadecimal,
i. start by dividing the decimal number by 16 taking note of the result and the remainder.
ii. divide the result obtained in (i) by 16 and take note of the new result and the remainder.
iii. repeat steps i and ii until the result is 0.
iv. the result is a combination of the remainders starting from the last.
16 | 596
16 | 37 r 4
16 | 2 r 5
| 0 r 2
Now combine the remainders starting from the bottom up. i.e
254₁₆
Therefore, (596)₁₀= ( 254)₁₆
(c) convert ( 101011101)₂ = ( )₁₆
This means that (101011101)₂ be converted to base 16 (hexadecimal).
To convert from binary to hexadecimal,
i. starting from the rightmost bit, group the binary digits into a group of 4 bits as follows
101011101 => 1 0101 1101
ii. the group that does not contain 4 bits is padded with 0s
101011101 => 0001 0101 1101
iii. using the hexadecimal table, convert each group to hexadecimal as follows.
0001 = 1
0101 = 5
1101 = D
iv. combine the result
15D
Therefore, ( 101011101)₂ = ( 15D)₁₆
(d) convert(37)₁₀= ( )₂
This means that (37)₁₀ be converted to base 2 (binary).
To convert from decimal to binary,
i. start by dividing the decimal number by 2 taking note of the result and the remainder.
ii. divide the result obtained in (i) by 2 and take note of the new result and the remainder.
iii. repeat steps i and ii until the result is 0.
iv. the result is a combination of the remainders starting from the last.
2 | 37
2 | 18 r 1
2 | 9 r 0
2 | 4 r 1
2 | 2 r 0
2 | 1 r 0
| 0 r 1
Now combine the remainders starting from the bottom up. i.e
100101₂
Therefore, (37)₁₀= ( 100101)₂

Select statements about Multiprocessors that are FALSE. a. Asymmetric multiprocessors are a popular form of tightly coupled architecture b. Symmetric multiprocessors are a popular form of tightly coupled architecture c. Tightly coupled multiprocessors share a single centralized memory, which requires an operating system to synchronize processes carefully to ensure protection d. Loosely coupled multiprocessors have a physically distributed memory and are also known as distributed systems
Answer:
The statement about Multiprocessors that is FALSE is:
a. Asymmetric multiprocessors are a popular form of tightly coupled architecture
Explanation:
Symmetric multiprocessors house two or more identical processors sharing a single main memory. The multiprocessors are tightly coupled, and all of them can access all the connected devices without any preferential treatment of one over the others. This is unlike asymmetric multiprocessors that do not share a single main memory. Instead, they have distributed memories.

Software that enables the organization to centralize data is called A. Data Repository B. Data Base Management System C. Data Warehouse D. Data Mart E. Data File
Answer:
B. Data Base Management System
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Hence, a software that enables the organization to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data, is called a Data Base Management System (DBMS).

A major university develops an assessment that is meant to provide data on whether potential students will be successful at the university level. If there is a relationship between the results of the assessment and student success, that will best indicate that the assessment has:___.
Answer:
Predictive validity.
Explanation:
A correlation can be defined as a numerical measure of the relationship existing between two variables (x and y).
In Mathematics and Statistics, a group of data can either be negatively correlated, positively correlated or not correlated at all.
1. For a negative correlation: a set of values in a data increases, when the other set begins to decrease. Here, the correlation coefficient is less than zero (0).
2. For a positive correlation: a set of values in a data increases, when the other set also increases. Here, the correlation coefficient is greater than zero (0).
3. For no or zero correlation: a set of values in a data has no effect on the other set. Here, the correlation coefficient is equal to zero (0).
A predictive validity can be defined as a measure of the extent to which a test score on a scale is able to predict scores based on certain criteria. Thus, it's a measure of the degree to which a certain criteria can predict future behavior or performance.
One of the most common area in which predictive validity is used is in university or college admissions such as in how scores on an assessment or test are related to performance based on a standard or criterion.
In this scenario, there exists a statistical relationship between the results of the assessment conducted and number of students who were successful. Thus, this will best indicate that the assessment has predictive validity.

Explanation:
Suppose a class Car and its subclass Honda both have a method called speed as part of the class definition. rentalH refers to an object of the type Honda and the following statements are found in the code: rentalh.cost(); super.speed(); what will the first statement do?
A. Nothing will be called since the code will not compile as a result of multiple definitions of speed.
B. The cost method in Car will be called.
C. The cost method in Honda will be called.
D. Overloading will be used to determine which cost method to use.
Answer:
C. The cost method in Honda will be called.
Explanation:
The first statement will cause the cost method in Honda to be called. This is because rentalh is a object of the subclass Honda. Therefore, any method that is called using this object variable will target the elements within the Honda subclass. In this case, the cost() method is being called using the rentalh variable which will look for the cost() method within the scope of the Honda subclass. In order to target the parent class Car it would need to be called using the super variable as in statement 2.

Produce a program using a loop that requests for 8 floating point numbers from a user.once provided the program should calculate the average of all numbers that are less than 10.5
Answer:
The program in Python is as follows:
total = 0
count = 0
for i in range(8):
num = float(input())
if num < 10.5:
total+=num
count+=1
print("Average: ",total/count)
Explanation:
This initializes the total to 0
total = 0
This initializes the count to 0
count = 0
This loop is executed 8 times
for i in range(8):
This request for float number
num = float(input())
If input is less than 10.5
if num < 10.5:
The sum is taken
total+=num
And count is incremented by 1
count+=1
The loop ends here
This calculates and prints the average
print("Average: ",total/count)
What security weaknesses/vulnerabilities exist in Wireless local area network device hardware and software?
Answer:
Explanation:
There are many weaknesses/vulnerabilities, some of which are the following...
Default Network Hardware, many individuals will go out and buy a new router and install it in their home. These devices come with a preset configuration including a preset security password which is many times a default password used for every router of the same model. This can be easily obtained by anyone who can then access the network.
Access Point hacking, an experienced individual can use a packet sniffer to detect the SSID that is frequently sent from the router in order to create an access point to be able to access the network.
WEP encryption is another vulnerability. These are very low security passwords that can be cracked using different software in a short period of time.
These are some of many vulnerabilities that wireless local networks have, but there are also many precautions and security measures that can be taken to prevent them.

Answer:
Cognitive loadLanguageWatchEditIn cognitive psychology, cognitive load refers to the used amount of working memory resources. There are three types of cognitive load: intrinsic cognitive load is the effort associated with a specific topic; extraneous cognitive load refers to the way information or tasks are presented to a learner; and germane cognitive load refers to the work put into creating a permanent store of knowledge (a schema).Cognitive load theory was developed in the late 1980s out of a study of problem solving by John Sweller.[1] Sweller argued that instructional design can be used to reduce cognitive load in learners. Much later, other researchers developed a way to measure perceived mental effort which is indicative of cognitive load.[2][3] Task-invoked pupillary response is a reliable and sensitive measurement of cognitive load that is directly related to working memory.[4] Information may only be stored in long term memory after first being attended to, and processed by, working memory. Working memory, however, is extremely limited in both capacity and duration. These limitations will, under some conditions, impede learning. Heavy cognitive load can have negative effects on task completion, and it is important to note that the experience of cognitive load is not the same in everyone. The elderly, students, and children experience different, and more often higher, amounts of cognitive load.The fundamental tenet of cognitive load theory is that the quality of instructional design will be raised if greater consideration is given to the role and limitations of working memory. With increased distractions, particularly from cell phone use, students are more prone to experiencing high cognitive load which can reduce academic success.[5]Explanation:

If an audio signal is to be coded, either for compression or for digital transmission, it must undergo some form of quantization. Most often, a general technique known as vector quantization is employed for this task, but this technique must be tailored to the specific application so it will not be addressed here. In this assignment, we will observe the effect of uniformly quantizing the samples of two audio signals.
a) Record your voice for 4 seconds and play it again using predefined MATLAB audio functions.
b) Use your Uquant function to quantize each of these signals to 7, 4, 2 and 1 bits/sample.
c) Listen to the original and quantized signals and answer the following questions using the comments in the same MATLAB file:
1- For each signal, describe the change in quality as the number of b/sample is reduced?
2- For each signal, is there a point at which the signal quality deteriorates drastically?
3- At what point (if any) does it become incomprehensible?
4- Which signal's quality deteriorates faster as the number of levels decreases?
