Using A Virtual Private Network ( Vpn ) - 1141 Words

Section 1.0 The world is constantly changing especially in technology. Each day new software and hardware is created to accomplish tasks that were not possible before. These new software’s and hardware’s offers new problems to come with these new accomplishments. Businesses are constantly looking for ways to make their employees more efficient. Allowing employees to communicate not just in the office, but remotely is being a requirement at this day and time. This company could make use of a Virtual Private Network (VPN) that routes through the firewall. The VPN would allow easy access to the company network for authorized employees. A VPN would allow the company to have employees that telecommute, work from home, or remote employees. It would allow our employees that travel frequently – like salesmen – to connect from anywhere they may be. The VPN would allow for a more flexible work day, and help work get done when it needs to be done instead of during normal business hours. The VPN will run through the company firewall to help limit the traffic through to legitimate business traffic. The company must first be aware and understand the risks of a VPN and firewall. This knowledge will help the company make the right decision for this technology. A VPN and firewall solution is different for every network, and must be customized to this company’s network. There is also risks to not using these tools. It is important for the company to see this risks as well, soShow MoreRelatedVirtual Private Network vs. Dial-up Remote Access Solutions1420 Words   |  6 PagesMost companies need to be able to access their work from many locations, including home and while traveling. The solution that allows them to access the network is one of two ways to access their network. The first is through a VPN (virtual private network) that allows the user access to remotely log in easily and quickly. The other way is through a dial up remote connection; this way is a bit easier to set up but can become very costly in the long run.

Should cellphones be allowed to children of ages 6 to 12

There is a noticeable increment of cellphone usage between children of ages 6 to 12 in the last few years. The statistics show that â€Å"6 out of 10 children own a cellphones† (ConsumerReport.org). This report clearly shows that there are a large number of children who own a phone. Now, with the latest advanced technology we cannot do much to prevent minors from gaining access to this type of devices. However, what we need to concern about is the damage that phones can cause to children. Lately, there have been many cases of abduction of children by social networks, and also cases of theft of cell phones. Therefore, the debate regarding children using cellphones whether or not has created different types of concerns along parents and†¦show more content†¦Those important points made the affirmative side believe that cell phones are good for children because it provides them safeness and independence. On the article â€Å"Child Wants Cellphone; Reception Is Mixed† from New York Times, Lisa W. Foderaro says, that parents think that by giving their 6 or 8 year old children a phone they can approach them wherever they are located or cell phones are also as emergency backup system (Forderaro). On the same article Foderaro records that a mother Cindy O’Neill Vitale says, â€Å"I honestly believe that we live in a time now where it’s important to be able to have access for whatever reason† (Forderaro). On Pbs Children and Media Liz Perle, reports that parents are really concern about the safeness of their children. Therefore, they buy them a cell phone. Perle says, â€Å"My daughter got her first cell phone in 7th grade†¦because she took public transportation home from school, my husband and I decided it was a good idea from a safety standpoint† (Perle). People also believe that the missing rate has lowered because of the ownership of cell phones between children. According to David Finkelhor a writer for The Washington Post argues, cell phones are a key part of this explanation (Finkelhor). The author says, â€Å"that cellphones enable parents to figure out where their kids are when they don’t come home† (Filkelhor).

Name and briefly describe the three basic processes of respiration. Ans:1. Pulmonary ventilation is the movement of air in and out of the lungs due to contraction and relaxation of muscles that control the size of the thoracic cavity. 2. External respiration is the exchange of gases between the air in the alveoli and the blood in the pulmonary capillaries. 3. Internal respiration is the exchange of gases between the blood in the systemic capillaries and tissues. Link to: 22. 3 Inhalation and exhalation 58. Describe the inward forces of elastic recoil, and explain why the lungs do not normally collapse during expiration. Ans:Elastic recoil is the recoil of elastic fibers stretched during inspiration and the pull of the surface tension of alveolar fluid. Intrapleural pressure is always subatmospheric during normal breathing, which tends to pull lungs outward and to keep alveolar pressure from equalizing with atmospheric pressure. Surfactant in alveolar fluid decreases surface tension to help prevent collapse. Link to: 22. 3 Inhalation and exhalation Inhalation and exhalation, 22. 5: Oxygen and carbon and 22. 6: Respiration 59. In chronic emphysema, some alveoli merge together and some are replaced with fibrous connective tissue. In addition, the bronchioles are often inflamed, and expiratory volume is reduced. Using proper respiratory system terminology, explain at least four reasons why affected individuals will have problems with ventilation and external respiration. Ans:Answers could include: reduced compliance (reduces ability to increase thoracic volume); increased airway resistance (decreases tidal volume); decreased diffusion due to increased diffusion distance, decreased surface area, and changes in partial pressures of gases (altering gradients). Other answers may be acceptable.

Name and briefly describe the three basic processes of respiration. | Ans:|1. Pulmonary ventilation is the movement of air in and out of the lungs due to contraction and relaxation of muscles that control the size of the thoracic cavity. 2. External respiration is the exchange of gases between the air in the alveoli and the blood in the pulmonary capillaries. 3. Internal respiration is the exchange of gases between the blood in the systemic capillaries and tissues. | |Link to: 22. 3 Inhalation and exhalation| 58. |Describe the inward forces of elastic recoil, and explain why the lungs do not normally collapse during expiration. Ans:|Elastic recoil is the recoil of elastic fibers stretched during inspiration and the pull of the surface tension of alveolar fluid. Intrapleural pressure is always subatmospheric during normal breathing, which tends to pull lungs outward and to keep alveolar pressure from equalizing with atmospheric pressure. Surfactant in alveolar fluid decreases surface tension to help prevent collapse. | |Link to: 22. 3 Inhalation and exhalation Inhalation and exhalation, 22. 5: Oxygen and carbon and 22. 6: Respiration| 59. |In chronic emphysema, some alveoli merge together and some are replaced with fibrous connective tissue. In addition, the bronchioles are often inflamed, and expiratory volume is reduced. Using proper respiratory system terminology, explain at least four reasons why affected individuals will have problems with ventilation and external respiration. | Ans:|Answers could include: reduced compliance (reduces ability to increase thoracic volume); increased airway resistance (decreases tidal volume); decreased diffusion due to increased diffusion distance, decreased surface area, and changes in partial pressures of gases (altering gradients). Other answers may be acceptable. | How to cite Human aP Ch. 22 Respiratory System, Essay examples
