How To Manage A Computer Network

Today it is almost inconceivable for a company that do not have computers or a building or a high-tech company. If a company more than one computer, usually are linked in a LAN. These networks may be more or less sophisticated and cheaper or more expensive. Companies invest a lot (both in terms of time and money) on a local network, as there are many benefits that a local network, a business meeting and how it should be administered.

Some companies use a local network, so they depend heavily on the job forever. If the failure of the corporate network, you can see all the people talking in the hallways because they cannot do their job. This means that large losses for the company and creates risks to workers. All companies should consider their local networks, an important advantage and downtime must be avoided. This places high demands on the network of staff in these networks of approximately 100% of the clock is ticking.

The benefits of network management software
An important advantage of the installation and maintenance of LANs is the opportunity to improve communication and collaboration between employees and customers to create.

Security considerations: security of local area network can be an obstacle for aid and suffer. global security is an advantage, as it provides a central strategy for improving access and the safe handling and disaster. All information will be protected in the design and implementation of network security solution. In addition, networks of computers in the network create a security risk, and that makes it technically possible for someone too many computers on the network once access.

Economic considerations: the installation of a LAN is a relatively expensive project. Servers, cabling, switches, routers and software can be expensive and cannot be purchased without professional advice. Continued use of the secure network, and resource intensive and can be expensive.

Surprisingly, a LAN has a number of cost savings. Share resources avoid the need to buy for each device. Even more important is the security offered by the Internet. Data loss can be costly for society and in some cases, the chief of the cases to a complete stop. Network Equipment Administration should require a consistent routine data backup with regular checks on the quality of data – a practice that company huge sums of money in case of failure will save.

Computer network management: preliminary analysis of phase
The first phase of the computer network management is the source of the problem of identification (a preliminary study various options for different sizes can be considered useful) and the definition of the requirements. Examples of what is necessary to assess other network operating systems, messaging systems and other applications. The choice of hardware should also be considered. This is usually to define what the system should do, not what we should aspire to.

Computer network management: Design

The design objective is to determine how the requirements of the specification requirements. The current approach is too large and complex projects, which is broken into smaller, more manageable subprojects.

Computer network management: The Implementation phase

This phase includes the physical installation of the LAN. The cable is passed, it installs the software and computers and other equipment are created.

Network Computer Management: Integration and System Test

In this phase, the implementation of the network starts and routines adapted to the users and operators. The system should be tested, both to ensure the system meets the requirements of the specification and sufficiently stable for the central role of the organization.

Network Computer Management: Operation and Maintenance

Local networks are complex operating system routines. That is because it can have serious consequences in case of malfunction or unauthorized access of people to the system. Many companies have the care of employees is dedicated exclusively to the implementation and maintenance of computer networks, to drink.

Network Computer Management: Tools
Although the organization cannot be managers must also monitor the network for more than eight hours a day. In fact, some of the worst problems that can occur with nets during the night, when nobody can do in the network. With network management tools of quality, the organization can be sure that problems will be given to prevention and clean – and your network administrator for a moment the notice shall be served as an extraordinary error.

Computer Recycling Why You Shouldn’t Just Throw It Away

Computers are made up of a number of small and large components. Most of these components are made of materials that can pollute the environment. It is not possible to build computers without these materials, as they are the heart and soul of a computer, defining its performance and efficiency. These materials are safely contained within a computer and hence, as long as the computers are being used in homes and other places, they pose no problem. However, when they are thrown away with the other waste, they may prove toxic and poisonous, affecting the environment at different levels. Computer recycling is therefore necessary to avoid such harmful effects on the environment.

Computers are complex machines and are made up of a number of chemicals and materials, quite a few of which can be toxic. This directly affects the environment where these chemicals might be released. If computers are simply thrown away, they sit in the landfills along with all the other trash and slowly begin to disintegrate. In this process, all the chemicals leak into the environment, polluting the surroundings. The land is the first casualty of this pollution. However, these chemicals can have a surprisingly long life and can seep into the ground water as well. Poisonous metals like lead, cadmium and mercury from computers are one of the most common pollutants and these are well known to cause many health problems in people. Therefore the pollution arising from improper disposal of computers can be quite serious to the environment and can directly affect our health. This is why computer recycling is the need of the hour to avoid any potential hazards in the future.

If old computers are simply thrown away in the trash, they will be taken along with all the other garbage to the landfills where they will simply be dumped. As these chemicals don’t really degrade, they will slowly enter into the environment. The first damage they do is to the land – these toxic chemicals seep into the land, rendering it useless to grow crops. However, this is just the beginning. These can be washed down to other areas through rain water and can easily seep into the ground, contaminating ground water. There are hundreds of toxins out there in your computer, so you can imagine the level of pollution they can cause. Once water and land are contaminated, these chemicals easily find their way into our food chains. Thus computer recycling is necessary in order to avoid such a catastrophic scenario.

Recycling also helps reduce the overall greenhouse gas emission from computer manufacturing, thus helping the industry become more sustainable. As a consumer, you can significantly reduce your carbon footprint by recycling your old computer instead of throwing it away. This is true even for the industry as a whole and companies can be greener if they recycle.

Computer recycling is the only way in which the problem can be tackled. As newer and improved computers enter the market, the problem of e-waste is going to be really huge. People need to get rid of their computers and buy newer ones. However, do not forget to be environmentally responsible in the process. Only through a collective effort can the catastrophic effects of toxins on our health be averted.

How Computer Glasses Differ From Regular Eyeglasses

Computer Glasses

Dependency on computers is increasing with time, in fact today a large number of people spend long hours on computers. This increased usage of computer makes it mandatory to take some precautions and one such important precaution is wearing Computer Glasses.

What are Computer Glasses?

Computer Glasses are eyewear that have anti-reflective lenses. These lenses block harmful radiations and reduce glare thereby enhancing vision and focus while working on a computer.

These glasses are also prescribed to reduce the symptoms of Computer Vision Syndrome (CVS).

What is Computer Vision Syndrome (CVS)?

CVS describes a group of symptoms like eye strain, dry eyes, headache, blurred vision caused by prolonged computer use. These symptoms appear because the eyes and brain react differently to words on a computer screen than they do to printed text.

Whereas, if the person is over the age of 40, the problem may be due to onset of Presbyopia- a vision disorder in which the eye loses its ability to focus on nearby objects.

The question that comes to mind is, how are these computer glasses different from regular eyeglasses?

Difference between computer glasses and regular eyeglasses:

Regular eyeglasses are prescription glasses designed to improve vision. They make things, text and images appear clearer. These glasses are generally not coated with anti-reflective coating and therefore they do not protect eyes from harmful radiations caused by computers.

Computer glasses on the other hand come with anti-reflective lenses and therefore they reduce radiations coming from gadgets like computers. These glasses also alleviate CVS symptoms and protect eyestrain and headache caused due to prolonged working on computers.

These glasses can be worn by anyone belonging to any age group and do not have any side-effects on the eyes. Those with corrective vision can ask their optician for anti-reflective coating on their lenses.

Apart from radiations from computers, these glasses also eliminate glare/reflection caused from water, snow and other flat surfaces. By reducing these glares, they enhance driving, biking and other outdoor experiences. So those with perfect vision who prefer outdoor activities more than computers or any gadgets can also opt for these glasses.

These glasses are available in various styles, ranging from vintage to modern, from rimless to full rimmed, etc. Wearer can also choose material of glasses from plastic, metal, or ultra-light titanium.

The brand conscious need not worry as they can turn their branded pair into computer glasses by changing lenses or by adding anti-reflective coating to the lenses.

Computer is unavoidable, but its effect on eyes and CVS symptoms can be avoided by wearing Computer Glasses. Make wearing computer glasses a must to enhance visual experience.

Bypass Proxy Server And Get Around Blocked Websites The Simple Way

Intoduction on How To Get around blocked Sites And Circumvent Internet Censorship

Blocked websites are a result of various blocking applications set up on client computers or the organizations’ web proxies. In this case the companies’ or schools’ administrators enforce such restrictions using a firewall to filter specific websites companies or schools deemed not suitable to be accessed inside their institutions.

Firewall and web blocking application are similarly enforced by such countries as China, Iran Islamic Republic, UEA etc in order to filter particular contents these goverment consider not acceptable to be viewed by their respective citizens.

Most people identifies these computer programs as internet filters. Censorship opponents got a different term for them: Censorware. Whilst there are some noisy proponents and opponents of Internet censorship, it’s not always simple to carve up everyone into one side or another.

Circumventors are all applications, computer software, or techniques used to get around blocked sites, or bypass Internet filtering. These ranges from advanced computer software to quite simple manual steps, such as accessing a censored website storedon a search engine’s cache, instead of trying to access it directly.

Circumvention providers install software on a server in a non-blocked location and connects to this computer accessible to those accessing the Internet from a censored location. Circumvention providers varies from large business-oriented organisations offering circumvention services for different fees to individuals offering circumvention services for free.

There are a lot of circumvention techniques which could be applied under a number of different instances by different users. Not a single method fits all of the different users and the circumstances within which they find themselves. The grounds for internet censorship vary from justified desires to protect minors from inappropriate contents to undemocratic to control people access to information. Regardless of the censors’ reasons are, the consequence is the same: They limit access to the web pages they deem unacceptable.

There are a lot of software on the market that could restrict or bar access to particular Web sites. Despite the fact that it can be fairly hassle-free to install internet filtering software and block sites, unblocking sites and circumvent the filtering application can sometimes be a challenging job to execute.

There several methods to get around web restrictions , one of the popular ways to achieve this is to connect to Virtual Private Network (VPN). This is one of the easiest yet effective means to circumvent the filtering software, allowing you to gain access to virtually all if not all blacklisted web site.

Get around internet filters with Virtual Private Network

A virtual private network (VPN) is virtual connection made over the Internet or other public networks, allowing remote offices or individual to establish a encrypted link involving different locations with their organization’s network.

A VPN works by utilizing shared public infrastructure whilst protecting internet privacy by means of security procedures and tunneling protocols such as the Layer Two Tunneling Protocol (L2TP. Public Proxy Server

Another Alternative to connect to blocked site is to use external public servers. Proxy servers are computer hosts dedicated to get around web blocking software placed on on the computer and the firewall which can be accessed through the internet. Your computer or laptop connects to a proxy server and the proxy server is the one which establishes the connection with the blocked web site. The proxy server subsequently shows you the contents of the page. You could view the site and communicate with the web site via the proxy server- even though it is blocked by your computer or firewall.

This is accomplished simply because it is actually not your computer interacting with the web sites, but a third party – the proxy server that creates the connection with the blocked site directly

NOTE: Though some public proxy servers may promote themselves as “anonymous” several web-based circumvention are not. Some may not even be encrypted.

Please remember that encrypted websites begin with ” https” and are signified by the open lock icon in your internet browser shifting to the locked position. When you send your internet requests unencrypted, they can be easily intercepted in any step on the way of transmission, from your home or office router to your internet service provider.

One thing to take into account is that since the web addresses of public circumventors are easily identified, many Internet filters applications already have these services on their block lists, just as many governments that enforce internet censorship at the national level. Browser-based circumvention could be a great alternative for users to bypass internet restrictions , if their services haven’t yet blocked

SSH Connection

Secure Shell or SSH is a network protocol that lets data to be exchanged using secure channel between two networked devices. Other Tunneling/ Unblocking Services There are a lot of of tunneling services and software you can use to gain access to blocked internet sites or applications. Essentially by using their services your online connections are rerouted to their servers with no limitations. Some are completely free to use, some are free with reasonably limited time usage and bandwith cap.

Top Five Jobs For Felons

Finding employment after being released from prison can be one of the most difficult tasks a felon faces. No one wants to hire you but parole terms require you to have a job or go back to jail. Even if you do not have parole requirements, you have to support yourself and face the question on every job applicatrion:

Have you ever been convicted of a felony?

Over 80% of all employers use some form of background check today which greatly limits the job paths available to convicted felons and even those convicted of misdemeanors.

Here are some jobs that are available:

#3 Start your own business

This is one of the best options for ex-cons because you never have to go through a background check and never have to worry about being fired. The best businesses are low cost start-ups. Look for something you can do at home, on your computer, or something where people want to pay you to come to them. This avoids renting a storefront or office.
Some examples

Windshield repair – People pay you to come to their house and repair dings in their windshield. You can purchase a kit, practice on windshields in a junkyard until you are good enough, then offer your services through your local free newspaper.
Locksmith There are many places where you can train to be a locksmith, even home study courses.

The big advantage of starting your own business is that there are no background checks. I recommend you buy some books on starting your business and a book on creating a business plan. Some books on marketing your business and the difference between a sole-proprietorship and a corporation would also be a good idea. This is a huge topic and much too complicated to go into here but you must do some research and understand at least something about running a business before jumping in. The important thing to do is research and study business books first. Most businesses fail because the person who starts it knows nothing about business. They hope to hang out their sign and the money will come in. It never happens that way. You will need a plan and you should start small.

#2 Medical Tests

It may not sound glamorous, maybe even scary, but it pays real money and they do not ask any questions other than health related ones. There are many medical studies going on around the country. These are not all for cancer or heard disease either. Somewhere a company has a new product that heals scars. They want people with scars who will try their product and let them photograph the results.

Some company has a new tattoo removal system and they need people to test it on. Some of these jobs are outpatient type jobs where they pay you a few hundred dollars a month. Others are in-patient where you are kept in a hospital and monitored. These pay the most and may involve testing new drugs, anti depressants, or they may simply want to see how a healthy person reacts to an anti-inflammatory drug. You may even be one of the people who receive the placebo drug that does nothing and not the real drug. Check the Internet or if you have a local teaching hospital or research center they may be able to help too.

#1 Recommended Job – Online Freelance Work

This is the best job for a felon because it requires no background check, no drug tests, no psychological tests, no certifications or anything else. You are hired based on what you can do and nothing else matters.

I am talking about remote, work at home type jobs. Not the fake jobs you see on the Internet like those assemble-junk-at-home jobs or copying names from the phone book type jobs, or stuffing envelope jobs, those are all scams. There are no such jobs in existence. There are however many legitimate work at home opportunities where small companies hire you online and pay up-front. These jobs may last a day, a week, or a month. You can work multiple jobs at once if you want or you can take a break or vacation anytime you feel like it. If you only want to work one day a week, you can do it. You have complete control over how much you make and when you work and you never have to go to a job interview again.

If you are good with computers that helps but it is not necessary. These jobs vary depending on what the company needs. You work for one company of a few days then work for the next company. The jobs range from computer programming, to data entry, webpage design, editing and proofreading, recording voicemail welcome messages, editing video, doing web research, forum marketing, writing sales letters, and anything else that can be done remotely. These jobs are posted on special Hire-Me Network sites by companies. You look through the listings and pick a job you want, then tell the company what you want to be paid and when you can complete the job.

Some other options are

#5 Delivery Driver

Many companies are willing to hire felons as delivery people as long as you have a clean driving record and no DUI’s. UPS has been known to hire felons.

#4 Join the Army

You can find a link to the US Army policy on hiring felons below.

#7 Telephone Customer Service

Many companies are willing to hire felons to handle phone based customer service.

#6 Temp Agency

Temp agencies are a good option. You will have to explain what your conviction was for and convince them it will not affect your work. Many companies that would never consider hiring a felon full time, will hire people from a Temp Agency or even short term contract people without a background check.

#5 Family Business

You may be able to work in a family or friend’s business.

#3 Truck Driver

It is a myth that all trucking companies are willing to hire felons. It is also difficult because special licensing is required for larger trucks. If you are on parole this kind of work may not be possible because the job will likely require you to go out of state. If you are not on parole then this would not be a problem. Truck driving jobs are not a sure thing and if you lack experience it is unlikely you will be able to drive an 18 wheeler, maybe smaller trucks.

This is a small section taken from the book Jobs For Felons which is available at Amazon for $6.95 but you can also download a free copy on the web. These are the top 10 jobs but there are many more and the book also explains more about the #1 recommendation, freelance work. This is only a few of the listings available plus you can find many agencies that specialize in helping felons find jobs, how to answer the question “Have you ever been convicted of a felone?” during an interview so that you are not immediately out of consideration and much more.

It’s Very Hard To Imagine A World Without Computers!

It’s very hard to imagine a world without computers! Everywhere you look computers are at work attempting to provide one service or another and make our lives easier. Computers, in one form or another can be found in vehicles, from cars, trucks and motorcycles to larger scale methods of transportation such as airplanes and trains. They are in your television set, your VCR, your toaster oven, etc. But when we conjure up the image of a computer usually our first thought is of a PC, otherwise known as a personal computer.

Personal computers can be purchased either as desktops or laptops and have so many different uses. Most of us would be lost without one at home or work or both! Many public libraries provide computers for the use of patrons, as it is a service that is invaluable to every one of us. E-mail or electronic mail is the quickest way to communicate with one another.

With one click on the “send” button a message is sent through cyberspace and arrives at the recipient’s in box in a matter of seconds. Students of all ages reap the benefits of the Internet when it comes time to look up information for school papers.

And very few people would disagree that typing papers and reports on a computer is far superior to typing on those old rickety typewriters of yester years! And computers carry the added advantage of being able to save work for future use, which cuts down on a lot of headaches.

Computers process information and in some ways are very complex while in other ways are very simple to understand. To describe how they do this in brief, as a person types a series of words into the computer by way of the keyboard and with help from the mouse, they are able to view what they’re typing on the computer monitor (or computer screen) in front of them.

What could be simpler? In the meantime the inside of the computer is very busy going through the information that is being entered into it and organizing it in a fashion that will be understandable to the computer user. The individual busy typing away has the opportunity to save the work they are doing in two ways, by way of saving it to the hard disk or drive or by saving it to a floppy disk or CD. Some people choose to do both, which is often wise to do.

All computers are made with certain pieces of machinery that enable it to do its job. Describing it in a general way, every computer comes complete with its brain, or central processing unit (CPU), the memory bank (which is self explanatory, think of your own memory), the main circuit board (often referred to as a motherboard), the power supply which takes care of all electrical functions, the hard drive which is the permanent storage unit of the computer, the standard software (otherwise known as the operating system), the IDE (integrated drive electronics controller), the PCI (or peripheral component interconnect bus), the SCSI, pronounced oddly enough as “skuzzy” which is the small computer system from which scanners or printers can be plugged into, and the graphic card and sound card which takes care of visual information and aural data respectively. In order to utilize a graphics card one needs an AGP (or accelerated graphics port) in the computer.

Computer Networking – A Brief Introduction

Data communications and computer networking is a very significant part of data technology. Today, all businesses in the world desires a computer communications mesh works well, very fast and flexible get access to to data. Imagine no connection scheme at universities, clinics, informative organisations and multinational associations, the dispute is to broadcast with each other. In this item you will discover the straightforward recount of a computer network. The reason of this item is persons who desire the connection mesh of information, measures and networks.

Connecting to the mesh gear and components. For exchange of data and assets between two or more computers in the mesh is known. There are distinct kinds of computer systems for example LAN, MAN, WAN and wireless networks. The major flats are engaged, the infrastructure of a computer center, swap, router and modem, get access to issue and mesh business card and mesh cable.

LAN entails localized locality mesh and a mesh in a room in a construction or on a mesh of a little locality called “LAN. Man is for the Metropolitan Area Network and encompasses the mesh between two agencies in the city. WAN Network wide locality and manage not realise the attachment between two computers or more between the two towns and two nations and continents.

There are distinct topologies of computer networks. A personal topology characterises conceive or the conceive of a network. These topologies are celebrity topology, coach topology, mesh topology, celebrity topology, coach, etc. attached in a celebrity topology, each computer exactly into a mesh to a centered hub or swap, as we understand it. If all the computers in a celebrity topology is not awkward leverage on other computers on a network.

There are distinct measures and apparatus on your network. The most widespread benchmark for Ethernet LAN. key apparatus in a computer mesh is a hub, swap, router, modem and get access to issue, router, etc. These are two distinct mesh attachments, ordered and physical. All communications on the Internet is founded on the router. Hub / swap to the computers on the mesh can use.
