An Overview Of The Types Of Garage Doors Available

Although there are only three standard types of garage doors, there are several variations that can be found. Many are available only as custom options. The three types most often used for basic doors are the tilt-up, the sectional, and the swing or side hung. Which you select depends on the climate in which you live, the architecture of your home, and how much you wish to spend. With some styles, how long your driveway is can also enter into the decision.

The sectional style is comprised of strips, usually four that fold up as the door is opened. This is the most popular style for use with an automatic garage door opener. It takes up less space on the garage ceiling, and less driveway space to open or close. This means that the car may be parked within inches of the door. Also, in climates where winter may bring snow and ice, these doors do not need drifts to be cleared to operate.

A tilt-up door is made of one panel. It must first swing out before going up. It must have clearance in front of it, requiring much more room to operate than a sectional style. If the driveway is short or snow will drift in front of it, these are usually not the optimal choice. However, they are much less expensive than a sectional style and cost twenty-five to thirty-five percent less.

A side hung or swing hung door works like a standard door. When it is open, it does not nestle into the garage ceiling but instead stands along the side. It requires quite a lot of space, not only in front but all along the trajectory of its arc. In areas that receive much snow, this means the entire path may have to be cleared. Also, this style is not conducive to the use of automatic door openers.

All basic door types are offered in wood, steel, or plastic. Wooden ones are more expensive, both in terms of initial cost and maintenance. They must be repainted frequently and rot is a common problem, particularly at the bottom. Steel takes paint well, and fronts are normally embossed to simulate a wood grain. Plastic offers quiet operation and light weight, but some cannot be painted.

Garage doors in all materials and types are available with or without windows. Windows will increase the cost of the door, but can add a charming architectural touch to the home. For those who spend a lot of time in the garage, such as hobbyists, the additional light can be very welcome.

Doors can also be insulated to various levels. Many in colder regions consider insulation a necessity, but it can also be valuable even in more moderate climates. If there is a room over the garage, or if it is attached to the house, utility bills and comfort level can be affected.

There are many types of garage doors available. The styles, materials, and options will allow any homeowner to find one that will add functionality and beauty to the home.

Frame Relay Overview

We hope you found this Cisco certification article helpful. We pride ourselves on not only providing top notch Cisco CCNA exam information, but also providing you with the real world Cisco CCNA skills to advance in your networking career.

Frame Relay Overview

In preparation of our CCNA exam, we want to make sure we cover the various concepts that we could see on our Cisco CCNA exam. So to assist you, below we will discuss Frame Relay Overview.

Frame Relay is a connection-oriented Layer 2 protocol that allows several data connections(called virtual circuits) to be multiplexed onto a single physical link. Frame Relay relies on upper-layer protocols for error correction. Frame Relay specifies only the connection between a router and a service provider’s local access switching equipment. The data transmission within the service provider’s Frame Relay cloud is not specified. A connection identifier is used to map packets to outbound ports on the service provider’s switch. When the switch receives a frame, a lookup table is used to map the frame to the correct outbound port. The entire path to the destination is determined before the frame is sent.

Frame Relay Stack

Most Frame Relay functions exist at the lower two layers of the OSI Reference Model. Frame Relay is supported on the same physical serial connections that support point-to-point connections. Cisco routers support the following serial connections: EIA/TIA-232, EIA/TIA-449, V.35, X.21, EIA/TIA-530. Upper-layer information (such as IP data) is encapsulated by Frame Relay and is transmitted over the link.

Frame Relay Terms

BECN (Backward Explicit Congestion Notification)-A message sent to a source router when a Frame Relay switch recognizes congestion in the network. A BECN message requests a reduced data transmission rate.

CIR (Committed Information Rate)-The minimum guaranteed data transfer rate agreed to by the Frame Relay switch.

DLCI (Data Link Connection Identifier)-Identifies the logical circuit between the router and the Frame Relay switch.

FECN (Forward Explicit Congestion Notification)-A message sent to a destination device when a Frame Relay switch senses congestion in the network.

Inverse ARP-Routers use Inverse ARP to discover the network address of a device associated with a VC.

LMI (Local Management Interface)-A signaling standard used to manage the connection between the router and the Frame Relay switch. LMIs track and manage keepalive mechanisms, multicast messages, and status. LMI can be configured (in Cisco IOS 11.2 and later), but routers can autosense LMI types by sending a status request to the Frame Relay switch. The router configures itself to match the LMI type response. The three types of LMIs supported by Cisco Frame Relay switches are Cisco (developed by Cisco, StrataCom, Northern Telecom, and DEC), ansi Annex D (ANSI standard T1.617), and q933a (ITU-T Q.933 Annex A).

VC (virtual circuit)-A logical circuit between two network devices. A VC can be permanent (PVC) or switched (SVC). PVCs save bandwidth (there is no circuit establishment or teardown) but can be expensive. SVCs are established on-demand and are torn down when transmission is complete. VC status can be active, inactive, or deleted.

Dynamic Mapping with Inverse ARP

To correctly route packets, each DLCI must be mapped to a nexthop address. These addresses can be dynamically mapped using Inverse ARP or can be manually configured. After the address is mapped, it is stored in the router’s Frame Relay map table.

LMI Signaling Process 1 The router connects to a Frame Relay switch through a channel service unit/data service unit (CSU/DSU). 2 The router sends a VC status inquiry to the Frame Relay switch. 3 The switch responds with a status message that includes the DLCI’s information for the usable PVCs. 4 The router advertises itself by sending an Inverse ARP to each active DLCI. 5 The routers create map entries with the local DLCI and network-layer address of the remote routers. Static maps must be configured if Inverse ARP is not supported. 6 Inverse ARP messages are sent every 60 seconds. 7 LMI information is exchanged every 10 seconds.

Frame Relay Overview Summary

Frame Relay is a connection-oriented Layer 2 protocol that allows several data connections (VCs) to be multiplexed onto a single physical link.

Cisco routers support Frame Relay on the following types of serial connections: EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA/TIA-530.

Local DLCI addresses can be dynamically mapped using Inverse ARP or manually configured using static Frame Relay maps.

Local Management Interface (LMI) signaling is used by Frame Relay switches to manage connections and maintain status between the devices. The supported LMI types are cisco, ansi, and q933a.

Kindle Review: Some Facts About This Modern Technology

Ever since the launch of the Kindle, the device has sparked all kinds of mixed feelings among book lovers. Often, when you read a Kindle review, you may hear the reviewer expressive fear about the demise of print books. Many people have passionate sentimental ties to books as printed objects, and the idea of switching to ebooks turns a lot of people off. Some people fear that books as printed media will disappear. They don’t want to lose the experience of browsing in a bookstore and searching for a favorite title.

The Kindle was first introduced in 2007, having been developed by a subsidiary company of Amazon.com. Two updated version have appeared since its launch, along with an application that allows it to work on an iPhone. The device is lauded as the technology of the future. For this reason, it is often assumed that the Kindle has been primarily embraced by young people who have grown up with electronic media. However, interestingly, statistics indicate differently. 70% of Kindle users are above the age of 40, showing that this technology does not only appeal to younger generations.

If you are considering getting a Kindle, but not sure whether you want to, here are a few reasons why people have been satisfied with the device:

It is Portable

The Kindle is small and compact, and ideal for travel. When going on vacation, taking more than one book in your luggage or carry-on becomes heavy, awkward and tedious. But the Kindle allows you to bring an entire library with you wherever you go.

Titles Available

There are many, many books available in ebook form, which can be purchased and transferred to a Kindle for a very small fee. This saves the time it would take to search bookstores, and the money it would take to have physical copies shipped.

It is Durable

Physical books can easily become worn. Dust jackets tear, and pages become torn or stained. A Kindle can be taken to the pool or to a beach without the same fear of water damage that you would have with a hardcover or paperback.

Ecologically Sound

The Kindle is good for preserving trees, as it does not require paper the way that paperbacks and hardcovers do.

Here, however, are some cons cited by users of the Kindle:

A printed book will never run out of battery power, but the Kindle, like an iPod, will. To use it for long periods of time, you must carry your charger and find places to plug it in.

There are not many technical or reference books available for the Kindle, so it does not lend itself to research.

Since it is an electronic device, the Kindle, like a Cd player or laptop computer, will need to be powered down during the beginning and end of airplane flights.

While the Kindle will not sustain the same damage as print books, it is not the strongest of devices. It must be handled more gingerly than a book would need to be handled. If you break your Kindle, it’s like losing several books at once.

Fears that the Kindle will kill off print media seem unfounded at this point. However, it is definitely a technology that will stay around and grow, and can work along with printed books to provide readers with many options.
