Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.

LANs systems can be defined and connected in many different ways. This is the reason for the standardization for every one can have a common ground to start from. “The LANs described Herein are distinguished from other types of data networks in that they are optimized for a moderate size geographic area such as a single office building, warehouse, or a campus. The IEEE 802 LAN is a shared medium peer-to-peer communications network that broadcasts information for all stations to receive. As a consequence, it does not inherently provide privacy. The LAN enables stations to communicate directly using a common physical medium on a point-to-point basis without any intermediate switching node being required. There is always need for an access sublayer in order to arbitrate to access to the shared medium. The network is generally owned, used, and operated by a single organization. This is in contrast to Wide Area Networks (WANs) that interconnect communication facilities in different parts of a country or are used as a public utility. These LANs are also different from networks, such as backplane buses, that are optimized for the interconnection of devices on a desk top or components within a single piece of equipment.”(IEEE 802 Standard 1990) That is the standard definition for LANs by Institute of Electrical and Electronics Engineer committee 802. They are the committee used to set the standard in workmanship and operations for technicians that set-up and perform maintenance on LANs systems. And through all the technical words what they are trying to say is a LAN is a small area network that distributes information among computer in a small work environment unlike WANs that distribute information across global areas. “It is usually the case that LAN is owned by the same organization that owns the attached devices. For WANs, this is less often the case, or at least a significant fraction of the network assets are not owned. This has two implications. First, care must be taken in the choice of LAN, since there may be substantial capital investment (compared to dial-up or leased charges for wide-area networks) for both purchase and maintenance. Second, the network management responsibility for a local network falls solely on the user”. (Local and metropolitan area networks 1997).

The question now is you have a standard and you have a connection now how do you manage the system to run flawlessly?” Networks use protocols, or rules, to exchange information though a single shared connection. These protocols prevent collisions of data caused by simultaneous transmission between two or more computers. Computers on most LANs use protocols known as Ethernet or Token Ring. An Ethernet-linked computer checks if a shared connection is used. If not, the computer transmits data. Since computer can sense an idle connection and send data at the same time, transmitting computers continue to monitor their shared connection and stop transmitting if a collision occurs. Token Ring protocols pass a special message called a token through the network. A computer that receives the token is given permission to send a packet of information or, if the computer has no packet to send, it passed the token to the next computer.”(Local Area Network Microsoft 2000) I know that it is complicated to understand, but for the actual user the software takes care of most all of the management for you.

There are seven things that a LANs can do that you cannot with ease do with non-networked stand-alone systems. First sharing files ” A LAN enables many user to share a single copy of a file stored on a central file server computer.”(Introduction to Networking 1992) Transferring files “A LAN enables you to copy files from machine to machine without having to exchange floppy disks.”(Understanding Data Communications 1993) Access information and files “A LAN enables anyone to run the accounting software, for example, or other application software from any of the workstations”(Introduction to Networking 1992) Share applications “A LAN enables two people to use the same copy of the Microsoft Word word processing program simultaneously”(Introduction to Networking 1992) Simultaneously key data into an application. Printer sharing and electronic mail with in the system.

In conclusion the LAN has become essential in the modern work environment. The ever-growing need for advancement has become a very profitable industry in its self and it will continue to grow for a long time to come. For now we are barely skimming the possibilities and uses for this new networking technology.

You have no doubt experienced the aggravation that goes along with a PC that is running slow, locking up, or otherwise misbehaving. It seems to happen only when you have an important task at hand or are in a big hurry. Fixing slow computer issues normally should fall only to the experts, but with the right advice and a little software, you can do it yourself without making things worse.

The number one reason computers run slow is a corrupted registry database. This is a complex, hidden database that in part of your computer’s operating system. It stores virtually all of the information about your computer’s configuration for both hardware and software. When you install lots of programs, get a virus, or have other disk issues, your registry can get errors or corrupted.

The result of this corruption is a slow computer. My advice if you want to go about fixing slow computer issues is to get a good registry cleaning software program. With these small utilities, it makes fixing slow computer issues a snap. You don’t have to be an expert- the software does all the work by scanning your hard drive and then automatically fixing the errors that it finds.

Find a highly-rated registry cleaning utility and keep it handy at all times. Scan your computer once a month for registry errors – you will find that your machine will run faster, better and with less lockups and reboots. A clean registry database is the key for a healthy computer. It’s cheap insurance for when disaster strikes.

Computers have continued to evolve since their inception decades ago and today we can definitely proclaim that we are living in a computer age. There are few facets of our lives that remain untouched by computers today and the technology continues to develop all the time. What is needed as a result are skilled professionals who are trained in designing, adapting, maintaining and implementing these new technologies and making our lives more productive as a result.

Computer training can be divided into a number of sub-specialties that include computer hardware, computer networking, computer software, and Web development. For those students who have an interest in math and science and show an aptitude for problem solving and analytical skills, a career in computers might be the right one for you. Working towards a career in computers can be done in several ways. You can opt for Associate, Bachelor’s, or Master’s degree programs and / or complete various certifications and certificate programs. Some employers require specific certifications in addition to your degree while others may need only a certification or two. It is therefore sensible to research the jobs that you are interested in and find out what exactly is demanded from a potential job applicant. In general, there are three main fields of study that you can choose from – a computer science degree, a computer networking and technology degree, and a computer programming degree.

Computer Science Degrees – Students interested in computer science degrees might be surprised to discover that the curriculum is barely about computers. Computer science degrees aim to prepare students to understand the technology behind computers and to analyze and solve problems and develop new technologies. There is a strong focus on mathematical computing and data analysis making computer sciences an extremely math-oriented program. As a graduate with a computer science degree, you can expect to spend a large part of your education and career in research. Colleges offer a wide range of computer science degrees from Associate’s to Masters but the minimum requirement for most employers is normally a four-year Bachelor’s degree. Many schools also offer a computer science degree program in tandem with another specialization such as engineering or information sciences for those students who want to diversify into more specific fields after they graduate. Employment opportunities are assured to computer science students as companies are always in need of professionals to develop and maintain their software and hardware. If you want the upper hand in the competitive IT market, a computer science degree would be very useful.

Computer Programming Degrees – Computer programming as a career looks to be stable over the next few years. As long as students are prepared to be up-to-date with the current advancements and technological certifications, there should be no dearth of job opportunities for graduates with a computer programming degree. Computer programmers are those professionals who develop, test and maintain the programs that determine a computer’s functions. Programmers create new computer languages and tools to make computers do specific tasks. Top employers of computer programmers include software development companies who create packaged and specialized software. These could range from general use software, games, educational packages and the like. Programmers with a strong technical base and skills to understand a client’s requirements are always in demand. Web-based organizations, multimedia companies, wireless applications, cyber security are all up and coming new arenas that programming graduates can look forward to as challenging job prospects.

Computer Technology and Networking Degree – A degree in networking and technology will introduce you to the latest theories and practices in computer networking and technology. Students will learn about operating systems of computer networks and will be trained in installing and maintaining the various structures and components of these networks. Job possibilities include becoming a network administrator, computer support specialist or a network systems analyst. Statistics indicate that as industries and businesses rely more and more heavily on the Internet and computer technology, the demand for such jobs will only increase.

Computer technology and network connections have grown to become central in our lives today. With the increased usage and dependability on computers, the crimes associated with them have risen in popularity to match this growth in usage. As a result, hacking has become a prevalent issue, and most of the time the consequences of a hack can have adverse results to the victim of an infected website.

Years ago, no one had to worry about hackers breaking into their website and installing Trojan viruses, or using your website to send attacks against others. Now that things have changed, people need to be aware of how to protect their website from harmful intrusions and how to stop hackers. Hacking has evolved quite a bit over the years. Why do they hack websites? The most common reason is to steal money. Some times hacking is for blackmail. Sometimes hacking is for revenge, or stalking or fame.

One of the basic fears for the minority of website owners is being the victim of a vicious hack attack. However, the majority of website owners are confident that their system will not be broken into because there is nothing in the site that could be of interest to the hacker. Nothing can be farther from the truth. The internet is prevalent with countless possibilities. Your website can be a launching point for other attacks. Hackers could use your system as a staging-off point to carry out attacks to other computers. This is a regular occurrence on the net. Many Denial of Service (DoS) attacks are executed in this manner.

Everyone needs to worry about hackers. Hackers do not discriminate when it comes to whose website they hack. In fact, smaller websites tend to get hacked more than larger websites. With so much of the world dependent on computers, hackers have become a powerful force and everyone must be aware of this or suffer the consequences of a hacked website.

If you have ever had your website hacked then you are all too familiar with that sickening feeling in your stomach caused by mixed feelings including violated, vulnerable, helpless, confused, angry and disgusted. If you have had your website hacked then you are not alone. There are a countless number of hacked websites, many of which do not even know that they are a website infected by a malicious hacker. According to the 2009 Security Threat Report from Sophos, one new infected Web page is discovered every 4.5 seconds.

Why then are there so many hacked and infected websites? Many website owners do not see the need for preventative measures – until their website has been infected. Most website owners spend most of their time, money and effort in building traffic to their website. There are often hundreds, perhaps even thousands of businesses offering the same or similar products and services so they put most of their efforts into the necessary steps to stay ahead of the competition. Adding website protection and security is very often put on the back burner.

You can spend time, money and effort in building traffic to your website, but you can’t even calculate the amount of trust lost if your site has been trying to infect all your visitors. If Google finds your site suspicious, they’ll add “This site may harm your computer” on all your Google search engine result pages (SERPs). How do you think this will affect your online marketing plans? Who knows how many of your customers will stop buying from you.

Hackers don’t leave traces of their attack on the outside. Your site may appear working normally on the surface but underneath, your system data might have been trashed, altered, copied or, at worse, deleted. Valuable data can be up for grab to the highest bidder. Not only can your data be sold online; enterprising hackers can also sell your security leaks to other hackers, spies and cyberterrorists.

It is considerably more expensive and more time-consuming to recover from a security incident than to take preventative measures ahead of time.

It is a more worthwhile use of your time to do everything you can to protect your site from all hackers, regardless of who they are, and understand that there will be a constant flood of attacks against your site. The more difficult you make it for someone to attack your website, the less likely they will even try.

Most people who have websites do not realize that it requires only a few simple steps to ensure some degree of security for your website at absolutely no cost to you. These steps take only minutes to do and no special software or programming knowledge is required. Granted, these basic security steps may not give you the full protection you need, but it will put you ahead of those who do not have any website protection and security at all.

If you have decided to go in for a brand new computer, this might be a daunting task. There are so many things that need to be considered. If you a new entrant into the world of computers, this could be even more daunting. Apart from choosing the best configuration, you are also faced with the task of ensuring that your computer does not start giving you a headache as soon as you bring it home.

When you plan to go in for a new computer, you will need a good checklist so that you get it right. The following are some good buying computer tips.

1. Define your budget and plan how much you are going to spend. When you set a budget, prepare for flexibility, since there might be marginal differences between what you plan for and what you actually get.

2. Decide the uses of the computer. Once you are clear about what you are going to use it for, you will be able to get a better idea of what components you will need to get fitted in. You do not need to go in for every component in the market and make a hole in your savings, just under the tag of “latest configuration”.

3. Plan for the future is one among the top buying computer tips. Remember that technology is ever changing. Therefore, you might need to upgrade your computer as time goes by. Ensure that when you get your computer, it allows you to upgrade it.

4. Balance out the performance of the machine. This is often overlooked when a person buys a new computer. Quite often, people are so obsessed with the latest processor, that they forget to check on how much memory they need to get that processor performing perfectly. This will, in turn, lead to major headaches later on in time.

5. One of the most important buying computer tips is to get the proper software bundled into the computer and good post sales support. This is especially useful if you are not tech savvy. In these instances, all major software will come pre-installed with your machine, and you will just need to switch it on to use. In the even if your having any issues, there will always be support available to resolve your issues.

6. Ensure that the components you get are of good quality. There are many people who have their own local makes of hardware. While these come at a lower price, they prove to be costlier in the long run. Therefore, go in for quality components as this will save money for you as well as reduce the chances of your computer crashing.

7. Maintain a backup of your computer in the case of any crashes. This can be done if you have a disk drive. You can also get a backup disk at the point of purchase of your computer.

8. Shop around for the best deals. It is unwise to step into a shop and try to buy the best that they have. Remember that not all computers cost the same in all places. Therefore, try to get a better bargain and a better offer before you settle on just one.

Computer Graphics is the life line of today’s computer technology. Starting from small wall Posters to huge animations, CG is being used. system generated imagery is used on televisions, Mobile Phones, Newspaper etc.

We can classify the CG as 2D, 3D, 5D and Animated Graphics. With the improvement in the technology 3D graphics have become common, but 2D graphics are also widely used.

2D Graphics

These are the computer based digital image generation in a plane. Texts, Images etc are the examples of 2D Computer Graphics. 2D CG is widely used in the field of News Papers, Printed Advertising etc.

As the technology has improved, New software came to the computer field to lessen the efforts in making a computer graphics. Microsoft Paint is a simple example of 2D Computer Graphics software. Other software like Adobe Photoshop, Macromedia Flash, Corel Draw, PageMaker etc is also widely used in the 2D CG field.

3D Graphics

3D graphics are the representation of Objects with reference to 3 Co-Ordinates. 3D graphics become much popular now with the coming of new technologies and software. Major software used in 3D Computer Graphics includes, Autodesk 3D Max, Autodesk Maya, Cinema 4D etc.

Technologies in 3D graphics are developing lightning fast.

Animations

Animation is a sequence of graphics arranged together so that graphics are showed as a moving film. There are 2D as well as 3D Animation. Major Animation software include Macromedia Flash, Autodesk 3D Max, Maya etc.

Revolutionary technologies are expected in the coming years. Movies like Avtar, Alice in wonderland, Cats and Dogs etc are the examples of present day technologies

The field of computer technology is always changing fast. Whether you are a student, an employee, or a business owner, it is important to stay current to any technological changes the computer industry might implement by updating your computer skills regularly. A good way to do this is by taking computer training courses. With internet and the availability of online courses, it is very convenient to do so. Below are five reasons why computer training should be integrated into your education and skills set:

1) Students need to be proficient in using writing, slide presentation and spreadsheet software for their school assignments and projects. When they graduate, they will be ready to use these skills in the workplace.

2) With the recession still being felt, computer skills are always essential in the marketplace and will make you stand out against your competitors when applying for a job.

3) Performing more tasks accurately and efficiently for your employer can save them time and money. An example is learning how to build simple macros to speed up the work process. By demonstrating these skills and taking initiative, your employer may keep you longer.

4) Your updated computer skills will be useful if you are new to a company and are learning their system. Also, if a company changes their systems, you will have an easier transition and less technology anxiety, especially for the older workers.

5) In a competitive job market with time and budget constraints, computer training for managers and business owners are essential skills that should be upgraded and possibly certified to compete with the global marketplace.

I hope these reasons will give you the enthusiasm to continue learning about the changes and upgrading your computer skills. It will give you an edge over your competitors as computer training continues to be an important part of your ongoing education.
