ï»¿Check Download.com for the Best Free Security Software Around With viruses, spyware, adware and hackers threatening on every corner of the internet, it is essential that especially internet users protect their PCs as best as they can to not loose their files or even their whole PC. Buying security software at a local computer store can be very expensive, but protecting the PC does not necessarily have to cost private persons anything at all. Just by checking what for example download.com has available, computer users might be able to save as much as 50-100 Dollars and still be able to protect their PCs adequately. One part of the web page called antivirus, firewall and spyware offers different links to downloads from companies that help protect PCs from any harm. Most of the programs offered on the web page are free for download. Some of the programs are antivirus software, which generally will scan the PC according to your settings for example once a day. When the software finds a virus in any of the files on the PC it will put out a virus alarm in form of a message box. The PC users then have to decide in which way the PC should be cleaned. Some antivirus software will offer to delete the file, others save it in what is called a virus vault, where the virus cannot attack other files on the PC, while others clean the file if it is cleanable. Other programs offered on the page are firewalls. Firewalls protect the Pc from any attacks form the internet, such as hackers hacking into your PC, Trojan horses, viruses and more entering the PC is not possible, when a firewall is used and set to the proper security setting. Using a firewall is a good idea for any PC, but it is important to know that the way the firewall works it might also cause a few problems with software on the Pc that enters the Internet. Therefore firewalls need to be configured right to have a smooth running and protected PC. Many of the firewalls offered on this page are free for download, but generally most PCs have a built in firewall in their operating system that just needs to be activated or configured. The third major kind of protection software one can download form this website is spy or ad-aware detection. Spy and ad-aware are programs that are malicious for the PC user. These kind of malicious little programs are installed without the users proper knowledge and intercept or partially take control of the interactions of the PC with the internet without the users consent. Spywares do not just monitor the internet interactions, as the name suggests, it also collects personal information, can install additional software that will take over the control of the browser activity, accessing websites that will allow for example viruses to enter the PC. Spyware is also often called privacy-invasive software and something a PC as well as a user needs to be protected from. The download page does not only offer many of these programs for free, it will also offer patches and update files for these programs. Even though many of the companies offer the continuous automatic update to protect a PC from new viruses and other malware, some PC users prefer not to have an automatic update and download their own updates whenever they deem necessary. Whichever way one likes to update the PC, it is most important of all to know that PCs need to be protected and users do not need to spend tons of money in order to do so. Free programs available for download on download.com will give a PC similar protection and keep files and identity safe.

ï»¿The History of Writing (history of writing) Writing is commonly used by billions of people each day. However, many of us donâ€™t know the history of writing, and some of us would rather not ponder it for fear of getting a headache. Written communication is much needed today, and many societies could not survive without writing. Writing has a history like everything that is in existence today. The exact history of this form of communication may be clouded and even over exaggerated at times, but there are two known facts, writing has been used for a very long time and writing will be used for a very long time. The true beginning of writing is unknown, but it does have a comprehensive history. The first artistic paintings and writings were said to be done in the form of naturalistic paintings of animals and people in caves. The pictures were known as attempts to appease the spirits of animals that were needed to kill in the hunt. In ancient times pictures were also done of human beings. These pictures of humans were typically done in series, with a figure appearing in different physical positions progressively, which represented positions a ceremonial dance performed by ancient people. Progressively, the early societies began to stylize their messages, which were similar to using symbols to represent restrooms, handicap-accessible places, and international road signs. These stylized symbols are known a petroglyphs and hieroglyphs. The most famous system of hieroglyphs belonged to the ancient Egyptians who had hieroglyphics that were partially representational pictures that were stylized. Petrogylphs were often used by Native Americans as messages along trade routes, ritual information, and various other things. However, they were not as sophisticated as hieroglyphs. During this ancient period, Europeans preserved esoteric knowledge in runes and in an alphabetic writing system known as ogham. The Chinese culture also has a place in the history of writing. The culture began by writing like many others by using pictures then slowly moving to stylized pictures. However, over time the pictures became less representational and more abstract. Today, Chinese, Japanese, Korean, and other Asian languages are written with the use of ideeographs. An ideeograph is used to represent an idea instead of a word. Around 1700 B.C. a new form of writing appeared in the Middle Eastern cultures. During this time, the Phoenicians created an alphabet. This development was different from all others because the symbols represented sounds, not pictures or ideas. The combinations of sounds made up the words of the language, which was crucial in the history of writing. The alphabet developed by the Phoenicians spread to Northern Africa and became the system of the Arabs, and spread northwest to Greece. The Greek developed their own letters, which were modified even more to become the Cyrillic alphabets of Russia, the Balkans and the Romans. The Romans modified the alphabet and made it the alphabet that is recognized today. The history of writing developed even further into the 20th century. Following World War II, the Japanese and Chinese began to use the alphabet to represent the sounds of their languages. For these Asian cultures, the alphabetic system was easier to write by hand and to print economically, so it made life far simpler for those cultures. The artistic form of writing used by these Asian cultures will likely never die, but there are many advantages to using an alphabetic system, and many modern people of these cultures benefit handsomely from learning to read and write using the current alphabet. The history of writing is long and sometimes vague, but it can be seen as a necessary teaching that will help modern societies understand the importance of written communication, and understand how the world would be forever changed without it.

Web Hosting - Bandwidth and Server Load, What's That? Two key performance metrics will impact every web site owner sooner or later: bandwidth and server load. Bandwidth is the amount of network capacity available, and the term actually covers two different aspects. 'Bandwidth' can mean the measure of network capacity for web traffic back and forth at a given time. Or, it sometimes is used to mean the amount that is allowed for some interval, such as one month. Both are important. As files are transferred, emails sent and received, and web pages accessed, network bandwidth is being used. If you want to send water through a pipe, you have to have a pipe. Those pipes can vary in size and the amount of water going through them at any time can also vary. Total monthly bandwidth is a cap that hosting companies place on sites in order to share fairly a limited resource. Companies monitor sites in order to keep one site from accidentally or deliberately consuming all the network capacity. Similar considerations apply to instantaneous bandwidth, though companies usually have such large network 'pipes' that it's much less common for heavy use by one user to be a problem. Server load is a more generic concept. It often refers, in more technical discussions, solely to CPU utilization. The CPU (central processing unit) is the component in a computer that processes instructions from programs, ordering memory to be used a certain way, moving files from one place to the next and more. Every function you perform consumes some CPU and its role is so central (hence the name) that it has come to be used as a synonym for the computer itself. People point to their case and say 'That is the CPU'. But, the computer actually has memory, disk drive(s) and several other features required in order to do its job. Server load refers, in more general circumstances, to the amount of use of each of those other components in total. Disk drives can be busy fetching files which they do in pieces, which are then assembled in memory and presented on the monitor, all controlled by instructions managed by the CPU. Memory capacity is limited. It's often the case that not all programs can use as much as they need at the same time. Special operating system routines control who gets how much, when and for how long, sharing the total 'pool' among competing processes. So, how 'loaded' the server is at any given time or over time is a matter of how heavily used any one, or all, of these components are. Why should you care? Because every web site owner will want to understand why a server becomes slow or unresponsive, and be able to optimize their use of it. When you share a server with other sites, which is extremely common, the traffic other sites receive creates load on the server that can affect your site. There's a limited amount you can do to influence that situation. But if you're aware of it, you can request the company move you to a less heavily loaded server. Or, if the other site (which you generally have no visibility to) is misbehaving, it's possible to get them moved or banned. But when you have a dedicated server, you have much more control over load issues. You can optimize your own site's HTML pages and programs, tune a database and carry out other activities that maximize throughput. Your users will see that as quicker page accesses and a more enjoyable user experience.
