Explanation:

Answer: Devices connected in a Bluetooth network communicate with each other using ultra-high frequency (UHF) radio waves. These are electromagnetic waves with frequencies around 2.4 gigahertz (2.4 billion waves per second). UHF waves of different frequencies are used in microwave ovens, GPS systems and many other devices, White hat hackers employ the same methods of hacking as black hats, with one exception- they do it with permission from the owner of the system first, which makes the process completely legal. ... There are even courses, training, conferences and certifications for ethical hacking. A hub connects multiple computers together in a Local Area Network (LAN). All information sent to the hub is then sent through each port to every device in the network.

Hubs are unable to tell one computer from another, so they receive information on one port and then blindly forward it to all other ports — whether it was intended for those computers or not.

So even though you may only want to send information to one other computer, if you have five total computers on your network, then there will be four other computers receiving data that wasn’t intended for them.

Infrared laser systems can also be used for long-range communication (up to about 2.4 kilometres), with a maximum projected data rate of 16 Mbps. ... An infrared transmitting device, either a light-emitting diode (LED) or a laser diode, converts an electrical signal to an optical signal.

Web Browser is a software which is used to browse and display pages available over internet whereas web server is a software which provides these documents when requested by web browsers. ... Web browser sends an HTTP Request and gets a HTTP Response. Web server receives HTTP Request and sends a HTTP Response.

Simple LANs generally consist of cabling and one or more switches. A switch can be connected to a router, cable modem, or ADSL modem for Internet access. A LAN can include a wide variety of other network devices such as firewalls, load balancers, and network intrusion detection.

Coaxial cable, or coax (pronounced /ˈkoʊ. æks/) is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.

Terrestrial microwave- The most common type of microwave antenna is the parabolic “dish.”A typical size is about 3 m in diameter. The antenna is fixed rigidly and focuses a narrowbeam to achieve line-of-sight transmission to the receiving antenna. Microwave antennasare usually located at substantial heights above ground level to extend the range betweenantennas and to be able to transmit over intervening obstacles. To achieve long-distancetransmission, a series of microwave relay towers is used, and point-to-point microwave linksare strung together over the desired distance. Used in long haul telecommunicationsservice, as an alternative to coaxial cable or optical fiber.

You can implement a firewall in either hardware or software form, or a combination of both. Firewalls prevent unauthorized internet users from accessing private networks connected to the internet, especially intranets

There are billions of devices connected to the Internet, and hundreds of different kinds of devices: laptops, tablets, phones, refrigerators, handheld credit card readers, and so on. Protocols (standards) ensure that the variety of devices interact with each other smoothly.  There are a lot of protocols! The Internet was designed with several layers of abstraction that sort the protocols according to what part of the process they support.

Answer:

To ensue that data entering data is limited, Usually A dropdown list is used but here in the available option

Lookup list is correct.

Explanation:

Let explain why we have selected Lookup list

A lookup list is used to look for some value in a list.

For example in Excel we select a column for search which is basically limiting the value which we search.

Bound Value

we usually have 2 bounds ,

lower and upper bound

lower bound is the smallest value in a set while upper bound it the highest value in a set.

Short Text:

Short text is used to minimize the word.

For example instead of United States we simply write US

Date/Time are used for data/time value.

so the most appropriate answer is Lookup list.

Complete Question:

You are running an 802.11g wireless router in mixed mode. You have three 802.11g wireless NICs using the router. A new user connects using an 802.11b wireless NIC. What will happen?

Group of answer choices.

A. The user with 802.11b will access the network at 11Mbps while the users with 802.11g will access the network at 54 Mbps.

B. The user with 802.11b will not be able to communicate on the network.

C. The user with 802.11b will access the network at 11 Mbps. The users with 802.11g will access the network at 54 Mbps unless they are communicating with the 802.11b device,which will be at 11 Mbps.

D. All users will access the network at 11 Mbps.

Answer:

D. All users will access the network at 11 Mbps.

Explanation:

A 802.11g is one of the wireless network standards developed by the Institute of Electrical and Electronics Engineers (IEEE) which operates on a 2.4 GHz microwave bandwidth and as a result can only transmit over a short distance. The 802.11g has a data transfer rate or throughput of 54 megabits per seconds (Mbps).

Basically, the 802.11b is a similar standard to the 802.11g wireless standard that typically allows the transmission (transfer) of data for up to 11 megabits per seconds (Mbps).

In this scenario, you are running an 802.11g wireless router in mixed mode. You have three 802.11g wireless NICs using the router. A new user connects using an 802.11b wireless NIC.

Hence, what will happen is that, all the users will access the network at 11 Mbps.

convoy effect

Explanation:

The Convoy effect is an episode in Operating System, in which if the burst time of the first process is high among all the processes, then it effects the First-Come-First-Serve algorithm.

Just like in real incidents, when a convoy is heading first in the slows down the vehicles behind; same happens in the Operating System. If long CPU burst occupies first in the ready queue, then it slows, or even in some cases, block other low processes. This effect is also known as starvation.

Therefore, the correct answer is convoy effect.

Question: What are the advantages and disadvantages of top-down and bottom-up programming?

Answer:

Top-down programming is a process of writing programming codes that contain specific instructions for a computer to carry out the instructed task. Usually, Top-down programming comes as software that enables the division of problems that are initially complex into simpler parts. An example is a kind of software developed to give loans to worthy clients. The software may be broken down further to check the bank statements of the client, calculate the earning and spending capacity of the client, Amount paid on utilities.

Advantages of Top-down programming:

1. Top-down programming makes teamwork possible as a system is divided into sub-systems which individuals can handle separately before merging the sub-systems together.

2. Checks and testing become easy.

Disadvantages of Top-down programming:

1. Breaking systems into parts may be time-consuming as there is a need for more planning before working on individual sub-systems.

2. Error could be possible.

Bottom-up programming is a software of a method of design which is opposite to what the top-down programming does as the bottom-up programming works on the sub-systems first and then combine later into a bigger system. This makes use of the existing resources with the aim of generating a bigger result.

Advantages of Bottom-up programming:

1. Adaptability - Bottom-up programming makes adaptability easier.

2. When used in a company it gives all workers the room to make a contribution towards achieving bigger results, improving operations generally.

3. It makes one start a bigger project with the available resources.

Disadvantages of Bottom-up programming:

1. Result could be affected as some workers lack the needed experience to execute some tasks successfully.

2. Lack of desired unity among workers with differences in objectives resulting to endangering the result.

Question: How would you decide which one to use?

Answer:

It depends on the picture of how the result would look like, the goal of the organization employing it, the skill-set among workers available to do the task, the nature of the task. If a larger goal is to be achieved, smaller sub-systems could be used and joined at the end to get a system meaning bottom-up programming would be used. In cases for instance where output is to be determined for instance staff salaries, the output would be broken into simpler units to allow solutions for separate units then we could use top-down programming.

Question: Do you approach problems in your real life from a bottom-up or top-down approach?

Answer:

I approach problems from a top-down approach because it allows checks and testing easy, and the act of breaking systems into sub-systems makes it easy for me to approach each sub-system with a result-oriented plan.

Answer:

Some advantages of top-down are that you can start off from what you know and figure out what you need to complete it, the advantage to bottom-up is that you can make something new . if you are starting something from scratch and you don't know what the end goal might be you would use bottom-up but if you already have an idea or the final product of what you want you would go with the top-down approach.

The program is an illustration of lists and list manipulation

Lists are variables that are used to hold multiple values in one variable name

The program in Python, where comments are used to explain each line is as follows:

#This defines the swap function

def swap(arr, pos1, pos2):

    myList = arr[pos1]

    arr[pos1] = arr[pos2]

   arr[pos2] = myList    

#This initializes the list

terms = ["Bandwidth", "Hierarchy", "IPv6", "Software", "Firewall", "Cybersecurity", "Lists", "Program", "Logic", "Reliability"]

#This prints the list elements

print(terms)

#This swaps the second and the sixth list elements

swap(terms, 5, 1)

#This swaps the third and the fifth list elements

swap(terms, 2, 4)

#This swaps the fourth and the sixth list elements

swap(terms, 3, 5)

#This swaps the sixth and the seventh list elements

swap(terms, 5, 6)

#This swaps the seventh and the ninth list elements

swap(terms, 6, 8)

#This swaps the ninth and the tenth list elements

swap(terms, 8, 9)

#This prints the list elements

print(terms)
