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

Answers

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.

What are the advantages and disadvantages of top-down and bottom-up programming? How would you decide which one to use? Do you approach problems in your real life from a bottom-up or top-down approach?

Answers

Answer:

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.

Kayla wants to know whether she should set her network up as a WAN or a LAN. What are the three questions you would ask her, and how would those questions affect your recommendation?

Answers

Due to it's typically massive size, WAN's are almost always slower then a LAN. The further the distance, the slower the network. One of the big disadvantages to having a WAN is the cost it can incur. Having a private WAN can be expensive.

Answer:

I would ask her: One, how large will the business be? Two, how secure she wants/needs the connection to be. And three, how much money she is willing to spend to install and/or maintain her network.

Since Kayla is just starting her business, my recommendation would be to set up her network as a LAN. A LAN is a group of computers and network devices connected together, and most often reside in one building. Kayla's business will start small, so it is not needed to set up her network as a WAN. WAN's are usually not restricted to a geographical location, and can be expanded to cover a whole country, or even a planet. A LAN would make sense in the coverage aspect, since Kayla's business has not expanded yet.

Depending on how secure she wants her network to be, she can choose whether or not she uses WAN or LAN. WAN is less secure, as it covers a large geographical area, while LAN is more secure. LAN is more secure because it covers a smaller area. I would recommend using LAN as it is better to have a secure network as a business.  

Finally, Kayla needs to address the cost of setting up and maintaining a LAN or WAN. I would recommend that Kayla uses a LAN because as a starting business, it is important to allocate money properly. LAN's usually cost less to install and maintain due to it's smaller geographical radius, so it would be best to choose to set up her network as a LAN.

Answers

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.

Search instead for are Infra-red signals are suitable for long distance data communication..

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
