A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone. This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc. Server administration can usually be provided by the hosting company as an add-on service. In some cases a dedicated server can offer less overhead and a larger return on investment. Dedicated servers are most often housed in data centers, similar to colocation facilities, providing redundant power sources and HVAC systems. In contrast to collocation, the server hardware is owned by the provider and in some cases they will provide support for your operating system or applications.

Availability, price and employee familiarity often determines which operating systems are offered on dedicated servers. Variations of Linux (open source operating systems) are often included at no charge to the customer. Commercial operating systems include Microsoft Windows Server, provided through a special program called Microsoft SPLA. Red Hat Enterprise is a commercial version of Linux offered to hosting providers on a monthly fee basis. The monthly fee provides OS updates through the Red Hat Network using an application called up2date. Other operating systems are available from the open source community at no charge. These include CentOS, Fedora Core, Debian, and many other Linux distributions or BSD systems FreeBSD, NetBSD, OpenBSD.

Support for any of these operating systems typically depends on the level of management offered with a particular dedicated server plan. Operating system support may include updates to the core system in order to acquire the latest security fixes, patches, and system-wide vulnerability resolutions. Updates to core operating systems include kernel upgrades, service packs, application updates, and security patches that keep server secure and safe. Operating system updates and support relieves the burden of server management from the dedicated server owner.

The indigenous inhabitants of the islands of the Caribbean Sea, Mexico, and Mesoamerica have smoked cigars since as early as the 10th century, as evidenced by the discovery of a ceramic vessel at a Mayan archaeological site in Uaxactún, Guatemala. The vessel was decorated with the painted figure of a man smoking a primitive cigar.^{[citation needed]}

Explorer Christopher Columbus is generally credited with the introduction of tobacco to Europe. Two of Columbus's crewmen during his 1492 journey, Rodrigo de Jerez and Luis de Torres, are said to have encountered tobacco for the first time on the island of San Salvador in the Bahamas, when natives presented them with dry leaves that spread a peculiar fragrance. Tobacco was widely diffused among all of the islands of the Caribbean and therefore they again encountered it in Cuba, where Columbus and his men had settled.

Around 1592, the Spanish galleon San Clemente brought 50 kilograms (110 lb) of tobacco seed to the Philippines over the Acapulco-Manila trade route. The seed was then distributed among the Roman Catholic missions, where the clerics found excellent climates and soils for growing high-quality tobacco on Philippine soil.

In the 19th century, cigar smoking was common, while cigarettes were still comparatively rare. The cigar business was an important industry, and factories employed many people before mechanized manufacturing of cigars became practical. Many modern cigars, as a matter of prestige and quality, are still rolled by hand, most especially in Central America and Cuba: some boxes bear the phrase totalmente a mano (totally by hand) or hecho a mano (made by hand).

Tobacco leaves are harvested and aged using a process that combines use of heat and shade to reduce sugar and water content without causing the large leaves to rot. This first part of the process, called curing, takes between 25 and 45 days and varies substantially based upon climatic conditions as well as the construction of sheds or barns used to store harvested tobacco. The curing process is manipulated based upon the type of tobacco, and the desired color of the leaf. The second part of the process, called fermentation, is carried out under conditions designed to help the leaf die slowly. Temperature and humidity are controlled to ensure that the leaf continues to ferment, without rotting or disintegrating. This is where the flavor, burning, and aroma characteristics are primarily brought out in the leaf.

Once the leaves have aged properly, they are sorted for use as filler or wrapper based upon their appearance and overall quality. During this process, the leaves are continually moistened and handled carefully to ensure each leaf is best used according to its individual qualities. The leaf will continue to be baled, inspected, unbaled, reinspected, and baled again repeatedly as it continues its aging cycle. When the leaf has matured according to the manufacturer's specifications, it will be used in the production of a cigar.

Quality cigars are still hand-made. An experienced cigar-roller can produce hundreds of very good, nearly identical, cigars per day. The rollers keep the tobacco moist—especially the wrapper—and use specially designed crescent-shaped knives, called chavetas, to form the filler and wrapper leaves quickly and accurately. Once rolled, the cigars are stored in wooden forms as they dry, in which their uncapped ends are cut to a uniform size. From this stage, the cigar is a complete product that can be "laid down" and aged for decades if kept as close to 21°C (70°F), and 70% relative humidity, as the environment will allow. Once cigars have been purchased, proper storage is usually accomplished by keeping the cigars in a specialized wooden box, or humidor, where conditions can be carefully controlled for long periods of time. Even if a cigar becomes dry, it can be successfully re-humidified so long as it has not been handled carelessly.

Some cigars, especially premium brands, use different varieties of tobacco for the filler and the wrapper. "Long filler cigars" are a far higher quality of cigar, using long leaves throughout. These cigars also use a third variety of tobacco leaf, a "binder", between the filler and the outer wrapper. This permits the makers to use more delicate and attractive leaves as a wrapper. These high-quality cigars almost always blend varieties of tobacco. Even Cuban long-filler cigars will combine tobaccos from different parts of the island to incorporate several different flavors.

In low-grade and machine-made cigars, chopped up tobacco leaves are used for the filler, and long leaves or even a type of "paper" made from tobacco pulp is used for the wrapper which binds the cigar together. This alters the burning characteristics of the cigar, causing hand-made cigars to be sought-after.

Historically, a lector or reader was always employed to entertain the cigar factory workers. This practice became obsolete once audio books for portable music players became available, but it is still practiced in some Cuban factories. The name for the Montecristo cigar brand may have arisen from this practice.

Backpacking is a term that has historically been used to denote a form of low-cost, independent international travel. Terms such as independent travel and/or budget travel are often used interchangeably with backpacking. The factors that traditionally differentiate backpacking from other forms of tourism include but are not limited to the following: use of public transport as a means of travel, preference of youth hostels to traditional hotels, length of the trip vs. conventional vacations, use of a backpack, an interest in meeting the locals as well as seeing the sights.

The definition of a backpacker has evolved as travelers from different cultures and regions participate and will continue to do so, preventing an air-tight definition. Recent research has found that, “...backpackers constituted a heterogeneous group with respect to the diversity of rationales and meanings attached to their travel experiences. ...They also displayed a common commitment to a non-institutionalised form of travel, which was central to their self-identification as backpackers” ^[1] Backpacking as a lifestyle and as a business has grown considerably in the 2000s^[2] as the commonplace of low-cost airlines,^[3] hostels or budget accommodation in many parts of the world, and digital communication and resources make planning, executing, and continuing a long-term backpacking trip easier than ever before.

While there is no definitive answer as to the precise origin of backpacking, its roots can be traced, at least partially, to the Hippie trail of the 1960s and 70s^[4], which in turn followed sections of the old Silk Road. In fact, some backpackers today seek to re-create that journey, albeit in a more comfortable manner, while capitalizing on the current popularity of the green movement ^[5]. Looking further into history, Giovanni Francesco Gemelli Careri has been cited by some^[6] as one of the world's first backpackers.

While travel along the old Hippie Trail has been rendered complicated since the early 80s due to unrest in Afghanistan, Iraq and Iran that continues today, backpacking has expanded to most regions of the world. In recent years, the increase of budget airlines and low-cost flights has contributed to this expansion. ^[7] At present, new "hippie trails" are being formed towards Northern Africa in places such as Morocco and Tunisia and other destinations being reached by low-cost airlines. ^[8]

Technological changes and improvements have also contributed to changes in backpacking. Traditionally backpackers did not travel with expensive electronic equipment such as laptop computers, digital cameras and PDAs due to concerns about theft, damage, and additional luggage weight. However, the desire to stay connected coupled with trends in lightweight electronics have given rise to the flashpacking trend, which has been in a state of continuous evolution in recent years ^[9]. Simultaneous with a change in “what” they’re carrying, backpacking is also becoming less and less reliant on the physical backpack in its initial form^[10] although the backpack can still be considered the primary luggage of backpackers.

Satellites used for television signals are generally in either naturally highly elliptical (with inclination of +/-63.4 degrees and orbital period of about 12 hours, also known as Molniya orbit) or geostationary orbit 37,000 km (22,300 miles) above the earth’s equator.

Satellite television, like other communications relayed by satellite, starts with a transmitting antenna located at an uplink facility. Uplink satellite dishes are very large, as much as 9 to 12 meters (30 to 40 feet) in diameter. The increased diameter results in more accurate aiming and increased signal strength at the satellite. The uplink dish is pointed toward a specific satellite and the uplinked signals are transmitted within a specific frequency range, so as to be received by one of the transponders tuned to that frequency range aboard that satellite. The transponder 'retransmits' the signals back to Earth but at a different frequency band (a process known as translation, used to avoid interference with the uplink signal), typically in the C-band (4–8 GHz) or K_u-band (12–18 GHz) or both. The leg of the signal path from the satellite to the receiving Earth station is called the downlink.

A typical satellite has up to 32 transponders for Ku-band and up to 24 for a C-band only satellite, or more for hybrid satellites. Typical transponders each have a bandwidth between 27 MHz and 50 MHz. Each geo-stationary C-band satellite needs to be spaced 2 degrees from the next satellite (to avoid interference). For K_u the spacing can be 1 degree. This means that there is an upper limit of 360/2 = 180 geostationary C-band satellites and 360/1 = 360 geostationary K_u-band satellites. C-band transmission is susceptible to terrestrial interference while K_u-band transmission is affected by rain (as water is an excellent absorber of microwaves at this particular frequency).

The downlinked satellite signal, quite weak after traveling the great distance (see inverse-square law), is collected by a parabolic receiving dish, which reflects the weak signal to the dish’s focal point. Mounted on brackets at the dish's focal point is a device called a feedhorn. This feedhorn is essentially the flared front-end of a section of waveguide that gathers the signals at or near the focal point and 'conducts' them to a probe or pickup connected to a low-noise block downconverter or LNB. The LNB amplifies the relatively weak signals, filters the block of frequencies in which the satellite TV signals are transmitted, and converts the block of frequencies to a lower frequency range in the L-band range. The evolution of LNBs was one of necessity and invention.

The original C-Band satellite TV systems used a Low Noise Amplifier connected to the feedhorn at the focal point of the dish. The amplified signal was then fed via very expensive 50 Ohm impedance coaxial cable to an indoor receiver or in other designs fed to a downconverter (a mixer and a voltage tuned oscillator with some filter circuitry) for downconversion to an intermediate frequency. The channel selection was controlled, typically by a voltage tuned oscillator with the tuning voltage being fed via a separate cable to the headend. But this simple design evolved.

Designs for microstrip based converters for Amateur Radio frequencies were adapted for the 4 GHz C-Band. Central to these designs was concept of block downconversion of a range of frequencies to a lower, and technologically more easily handled block of frequencies (intermediate frequency).

The advantages of using an LNB are that cheaper cable could be used to connect the indoor receiver with the satellite TV dish and LNB, and that the technology for handling the signal at L-Band and UHF was far cheaper than that for handling the signal at C-Band frequencies. The shift to cheaper technology from the 50 Ohm impedance cable and N-Connectors of the early C-Band systems to the cheaper 75 Ohm technology and F-Connectors allowed the early satellite TV receivers to use, what were in reality, modified UHF TV tuners which selected the satellite television channel for down conversion to another lower intermediate frequency centered on 70 MHz where it was demodulated. This shift allowed the satellite television DTH industry to change from being a largely hobbyist one where receivers were built in low numbers and complete systems were expensive (costing thousands of Dollars) to a far more commercial one of mass production.

Direct broadcast satellite dishes are fitted with an LNBF, which integrates the feedhorn with the LNB.

The satellite receiver demodulates and converts the signals to the desired form (outputs for television, audio, data, etc.). Sometimes, the receiver includes the capability to unscramble or decrypt; the receiver is then called an Integrated receiver/decoder or IRD. The cable connecting the receiver to the LNBF or LNB must be of the low loss type RG-6, quad shield RG-6 or RG-11, etc. It cannot be standard RG-59.
