What is the function of a firewall?

It is commonly known that Firewall is an imperative protection provided to PCs. This application is between the system and other network which controls the outgoing and incoming network traffic. It would depend on the rules of firewall as to which traffic is allowed and which is not.

Most people use routers at home in order to share internet connection between several devices. A system that is connected directly to the internet would have a public IP. So any netizen can reach it. Any network services that are running on the computer like that which comes with Windows for printer sharing and file, remote desktop would be accessible by the netizen.

Microsoft had introduced Firewall in Windows XP Service Pack 2, and it finally enabled a by default firewall in Windows. A firewall would obviously drop all incoming connections unless it has been specifically configured to allow incoming connections.

This would not allow people on the Internet from connecting to local network services on your system. It even controls access to the network services from other computers on local network. This is why user is asked as to what type of network it is when connected to Windows. If connected to home network the firewall provides access to these services. If it is connected to public network, the access would be denied by the firewall.

In case a network service is configured that no net connection would be allowed, there is a possibility that the services has security lapse and customized request would allow the attacker to run some code on the system. This would be prevented by the firewall thereby preventing the incoming connections from reaching these susceptible services.

Firewalls sit between a network say the Internet and the computer but it is protecting. Its main purpose for home users is blocking unnecessary incoming network traffic. It can also analyze the traffic that leaves or reaches the network as well as decides what can be done with it. Say for instance, a firewall could b configured in order to block some types of outgoing or suspicious traffic or even all transfer.

A firewall does have certain rules which denies as well as allows certain types of traffic. Say for instance it could allow connections to the server from specific IP address thereby dropping all link requests from somewhere else for safety.

Firewalls run in the laptop. It can also be a out-and-out hardware used for a corporate network. Corporate firewalls could examine outgoing traffic thereby ensuring that no malware was communicating through the network or observe employee’s network use as well as filter traffic. One can configure a firewall to only allow web browsing traffic and other applications.

avoid online shopping

Customers usually fall for several tag lines like “Hurry 2more days to go for off season sale” and so much more. It is these that customers get to see always. They fall for this despite knowing that sales always come up. It has been instilled into our brains that sale should be taken advantage of incase if it does not come up again.

People are normally motivated by a lost than a gain. This is what retailers take advantage of. Say for instance, there are online retailers who offer a free trial period. The customer is induced to think whether they give back the item and get nothing or order one to gain something. Most of the users choose the latter option. The customer is actually not losing anything but made to feel so. This is a behavioral psychology which is cashed upon.

Normally if you are provided something by someone you are highly obliged and consciously or sub- consciously give in return something. A common example is that of customers being provided free sample of a product. After using free sample customers would buy the product.

Online when you would sign up for free newsletter, user gets free content. One would feel like to provide something in return to content provider. Human beings are usually consistent as far as achieving a goal is concerned. When a user searches for a product the first thing that they notice other than the picture is the user ratings.

As human beings do pay heed to what others say especially while making important decisions. As per a research several people also take help of social media prior to taking a decision. User is more likely to use the services of a website that has testimonials than the one which does not have. This is what sellers take advantage of.

Always make a close notice to pricing. If you get a good deal think about why are you getting it? Thereafter think minutely about the purchase made online. Do ask some questions to yourself.

Installing the fonts easily with intuitive interfaces. Protect the fonts against it being deleted accidentally. You would obviously not like to lose expensive fonts. The font would be organized depending on the font manager. You can also store them in several directories to maintain order veneer.

Fonts are dynamically loaded in order to reduce usage of system resources. This also depends on font manager, but some allow loading as well as unloading fonts instead of loading them into memory at start up.

If you want to install a font in Windows, just move or copy target font files into C:\Windows\Fonts folder. There is a shortcut where you would have to right click on font files and choose Install to let the operating system handle it for you. You can just go through Font folder as well as delete files manually.

Font Frenzy is a program which has several useful tools that comes with four useful tools. FrenzyMan helps to add as well as install one or several files. Defrenzy deletes all the font except the ones that are shipped with the system. FrenzySnap would help to take a backup of the Font folder and Refrenzy restores the fonts that were backed up by FrenzySnap.

You can download free fonts and manage them in Windows. AMP viewer offers several installed and no-installed fonts. The fonts can be installed temporarily in case you want to test them or it is needed for some time.

Nexus Font is a program which instead of installing fonts to the system; it can be installed into Nexus Font itself. All the font loads are loaded into the program that is available to the system. As the nexus one would be closed, fonts become unavailable. This saves memory and space.

Suitcase Fusion is expensive but it’s worth it. This powerful font manager is more than an organizational aid. In-built QuickComp feature allows mixing as well as match several font combinations for experimentation. Fontspiration is an amazing feature which helps to locate new as well as interesting fonts to enhance creativity. Again font can be enabled and disabled to save system resources.
