Advanced security mechanism helps cost-effectively prevent theft of equipment and general damage in open-access areas

CHISAGO CITY, Minn. -- Kendall Howard today announced the launch of its Anti-Theft PC Security Stand, the industry's most advanced method for keeping PC hardware safe from theft and general damage.

"Organizations everywhere are seeking to protect their computer equipment and the intellectual property they store," said Randy Herreid, president and CEO, Kendall Howard. "Our new Anti-Theft PC Security Stand gives IT managers in corporate organizations a powerful, cost-effective deterrent while still allowing access to key technology resources." Unlike existing systems designed with plastic interlocks or cables that are quickly bypassed, the Kendall Howard stand is constructed with heavy-duty steel brackets that can be securely screwed to a desktop. The unit secures a small form factor PC and a 15-inch to 22-inch LCD monitor without limiting usage, such as the ability to tilt a computer screen up and down.

"The stand also prevents unauthorized access to the computer's hard drive," said Herreid. "This preventive measure has proven to significantly reduce the loss of equipment and, more importantly, of data held in the computers - the value of which is often in the hundreds of thousands of dollars."

There are many other computer theft and data recovery statistics that suggest preventive measures are vital to a corporation's bottom line, including:

* Eighty-five percent of organizations report that they have had a data breach event.

Scott and Scott LLP and Ponemon Institute LLC, May 15, 2007

* Only 35 percent of IT professionals in midmarket companies say they are equipped to deal with lost corporate or personal data.

King Research survey of IT professionals sponsored by KACE, March 2007

Computers often break down at the worst of all times. These problems can be averted, or at least minimized with preventive maintenance. Several methods of keeping computer hardware in good working order deal with the external components of the computer, such as the keyboard and monitor. For example, it is important to keep the processor away from excess heat and moisture. There are also computer hardware preventive maintenance software programs that can help with the upkeep of other internal aspects of a computer.

While it is rare to find a CMMS that works on all of a computer’s hardware, many different programs can be utilized simultaneously. Some computers have periodic automatic updates available that can be downloaded and used to improve the computer’s performance. Other software programs, known as disk defragmenters, manage hard drive space so that software programs take less time to access. Programs known as hardware diagnostic utilities can check the computer’s hardware components and alert the user about any potential failures. Since some new hardware will not always work on all computers and could cause existing hardware to malfunction, it is important to have a CMMS program to ensure that the new hardware is compatible with existing hardware.

Antivirus programs are another important component of computer hardware preventive maintenance software. Computer viruses have become increasingly common in recent years and can render a good computer useless. While computer viruses mainly attack software programs, they can ruin hardware as well. Several manufacturers make reliable antivirus software. A couple of well-known companies are Norton and McAfee. As with much preventive maintenance software, these programs are usually available for a free trial period before the user must pay a subscription fee.

Computer hardware preventive maintenance software is necessary to keep computers in good working order. This software manages aspects of computer hardware that would be difficult and time-consuming for even the most computer savvy users.

Preventive Maintenance Software Info features detailed information on preventive maintenance software for health care and correctional institutions, computer hardware, and personal assets, as well as reviews of preventive maintenance software companies. Preventive Maintenance Software Info is the sister site of Fleet Maintenance Software Web.

Cabinet hardware is an important detail to complete the beauty of your home. There are many varieties of cabinet hardware available on the market, and you can choose whatever fits your taste and style. Antique cabinet hardware is very popular, but is usually expensive. However, a collection of antique pieces would give your kitchen a certain artistic flair.

There are two basic aspects to a cabinet style: the structure and the look of the hardware used to compliment the cabinet. For example, if you have a cabinet of antique design and style then you can choose brushed-finish hardware.

A common antique style of cabinet can have a face frame with a brushed or a polished brass finish, and hardware complimenting the same. Antique copper, polished chrome, polished sterling, nickel, or aged bronze are some finishes used to complete a traditional and antique piece.

From the wide range of antique hardware available in the market, you can choose a decorative cast-iron vernacular cabinet latch, or slide-style cabinet latch. These are made of solid brass and are among the most decorative features of vintage furniture. They add a classic look to the furniture.

Suppliers of antique hardware boast of the uniqueness of the pieces they carry. They pick up these pieces from various places and try to collect a genuine antique piece. They hunt for genuine antiques from auctions, demolitions, and the like and, since these pieces are rare and much in demand, the prices are kept high.

Since an original antique piece is expensive, these suppliers sometimes make and sell reproductions. These kinds of piece are available in market and are bought by many people as the prices are much lower than the original piece. However, when purchasing an antique piece, one should make sure it is authentic.

The systems model of management demonstrates that communication is what is needed for executing managerial functions and for integrating the organization with the outside world. Point of sale hardware exactly performs this function with the help of Management Information System (MIS).

MIS can be defined as a formal system of gathering, integrating, comparing, analyzing and dispersing information internal and external to the enterprise in a timely, effective and efficient manner. MIS has to be tailored to specific needs and may include routine information, such as monthly reports, information that points out exceptions, especially at critical points and information necessary to predict the future.

Electronic equipment allows speedy and inexpensive crunching of gigantic quantities of data. The computer can, with proper programming, process data toward logical conclusions, classify them and make them readily available for a manager’s use. In fact, data do not become information until they are processed into a usable form that informs.

Information needs differ at various organizational levels. Therefore, the impact of point of sale hardware will also be different. At the supervisory level activities are usually highly programmable and repetitive. Consequently, the use of hardware is widespread at this level. Scheduling, daily planning and controlling of the operation are just a few examples.

Middle level managers, such as department heads are usually responsible for administration and coordination. But much of the information important to them is now also available to top management if the company has a comprehensive information system. For this reason, some people think that the computer will reduce the need for middle level managers. Others predict that their roles may be expanded and changed.

Top level managers are responsible for the strategy and overall policy of the organization. In addition to determining the general direction of the company, they have to do whole lot of other things. Hence, it is not easily programmable. Yet they can use the point of sale hardware to retrieve information from a database that facilitates the application of decision models.

Dozens new computer games are released by amateur and professional game developers every day. Some games remain in the player's mind for their complexity, challenge and fun experience, while others attending a temporary demand before falling into limbo of forgetfulness. Regardless the types of the games - action games, board games, puzzles or riddles, there’re common ingredients that make a great computer games.

Match the Complexity of the Game with Players’ Skill Level - A large number of the most memorable and great computer games include a selectable skill level to achieve the different challenges a player might want to take. A beginner may start with a low level portion of the game yet still enjoy the fun. As the player gets used to the game, he may demand more challenge and move to next level of the game. The harder the game the more rewarding the experience is.

Easy to Learn the Rules of the Gamers - The players come to a PC game for fun. They won’t spend hours to learn the rules of a new games before having fun. A game has to be simple from the playable perspective. A game too hard to understand may discourage the player no matter how good it may look. It is interesting to note how many old PC games based on text adventures without fancy graphics still remain popular. Riddle, a form of word puzzles and an ancient word game, have made its into computer games too. Some computer games have incorporated role-play, graphics and sound into riddles to make the experience of solving puzzles more fun and rewarding.

Role Play - For role play games, players want to have fun living the role of the chosen character so he or she needs to feel that it is the player who can control the outcome of the games. The idea of role-play has been widely used in other types of PC games to make a simple game more fun and interesting. Role-play could transform trivia to non-trivial.

Technology suits the current PC hardware and software - The average hardware and software capacity should be carefully assessed before developing a game. The experience of PC games are often limited by the player's computer hardware, software and system resources. Users with a powerful computer may find a game worthless if the story is great but the graphics are poor. Others may be frustrated with games with the look and feel of those belonging to the early day of computerized games. Configurability satisfies both types of players. A good computer game can automatically configure itself according to the hardware and system specs. It performs well on an average computer with the possibilities to improve the gaming experience in equipment with a higher capacity.

Save Time and Money with Training: Computer, Projector, and Sound System Equipment Rentals

Even if you own all the equipment you need for a computer training session you will save money by using the installation services of a computer rental company. Computer rental companies coordinate everything technical so you can concentrate on the execution of your computer training program.

Trainers can become technicians very quickly when training computer equipment doesn't work properly.

Training directors know how difficult it can be to 'work out all the bugs' before, during and after each training program.

Execution is the key to training results and efficiencies. If 20% of the computers don't work, you can have a training disaster on your hands.

Add up all the costs and distractions from your computer training goals. Put a value on your time, say $100 per hour. Now multiply the time you and your staff spent on hardware setup, delivery, installation, maintenance and removal. Keep in mind that all computers need to have the same configuration to maximize productivity.

Here is a quick checklist of common tasks that need to be accomplished on every computer training session.

1. Install same versions of operating systems and training software

2. Install sound system, projectors, printers

3. Run network cables

4. Tape down all wires

5. Connect to network services

6. Test each computer

7. Troubleshoot installation problems

8. Diagnose and fix all problems

9. Service equipment during training sessions including having spare equipment available.

10. At the end of the computer training, disconnect, pickup and return all the equipment to various locations in your company.

How many man-hours would it take for you and your company's staff to accomplish the classroom training setup, service and teardown?

Here are some things to find out if you use a computer rental company for computer training sessions:

Find out if the computer rental company has any experience with the classroom training hardware and software you need. If they do often they can remember all the pieces and parts that easily get overlooked by a non-experienced rental company.

Some rental companies will install software or 'image load' all rental computers prior to delivery.

For example, you can have your training program software and the OS of your choice installed on all desktop or laptop computers!

Have the computer rental technicians test each application by following your testing directions. This ensures that your training software will work as planned.

Make sure delivery, setup is planned well in advance of computer training sessions.

Make sure you are covered with an on-site service program! Ask for extra, spare equipment can even be included for your computer training class! Often you can get a spare unit for free!

Focus on your core competency...your computer training session. Don't be distracted by hardware and software problems. Let the experts focus on their core competency.. your computer training hardware installation and management!
