A modem is a hardware device that converts data between transmission media so that it can be transmitted from computer to computer. The goal is to produce a signal that can be transmitted and decoded to reproduce the original digital data. Modems can be used with any means of transmitting analog signals from light-emitting diodes to radio. A common type of modem is one that turns the digital data of a computer into modulated electrical signal for transmission over telephone lines and demodulated by another modem at the receiver side to recover the digital data. Modems are classified by the maximum amount of data they can send in a given unit of time expressed in bits per second or bytes per second. Modems can be classified by their symbol rate, measured in baud; the baud unit denotes symbols per second, or the number of times per second the modem sends a new signal. For example, the ITU V.21 standard used audio frequency-shift keying with two possible frequencies, corresponding to two distinct symbols, to carry 300 bits per second using 300 baud.
By contrast, the original ITU V.22 standard, which could transmit and receive four distinct symbols, transmitted 1,200 bits by sending 600 symbols per second using phase-shift keying News wire services in the 1920s used multiplex devices that satisfied the definition of a modem. However, the modem function was incidental to the multiplexing function, so they are not included in the history of modems. Modems grew out of the need to connect teleprinters over ordinary phone lines instead of the more expensive leased lines, used for current loop–based teleprinters and automated telegraphs. In 1941, the Allies developed a voice encryption system called SIGSALY which used a vocoder to digitize speech encrypted the speech with one-time pad and encoded the digital data as tones using frequency shift keying. Mass-produced modems in the United States began as part of the SAGE air-defense system in 1958, connecting terminals at various airbases, radar sites, command-and-control centers to the SAGE director centers scattered around the United States and Canada.
SAGE modems were described by AT&T's Bell Labs as conforming to their newly published Bell 101 dataset standard. While they ran on dedicated telephone lines, the devices at each end were no different from commercial acoustically coupled Bell 101, 110 baud modems; the 201A and 201B Data-Phones were synchronous modems using two-bit-per-baud phase-shift keying. The 201A operated half-duplex at 2,000 bit/s over normal phone lines, while the 201B provided full duplex 2,400 bit/s service on four-wire leased lines, the send and receive channels each running on their own set of two wires; the famous Bell 103A dataset standard was introduced by AT&T in 1962. It provided full-duplex service at 300 bit/s over normal phone lines. Frequency-shift keying was used, with the call originator transmitting at 1,070 or 1,270 Hz and the answering modem transmitting at 2,025 or 2,225 Hz; the available 103A2 gave an important boost to the use of remote low-speed terminals such as the Teletype Model 33 ASR and KSR, the IBM 2741.
AT&T reduced modem costs by introducing the answer-only 113B/C modems. For many years, the Bell System maintained a monopoly on the use of its phone lines and what devices could be connected to them. However, the FCC's seminal Carterfone Decision of 1968, the FCC concluded that electronic devices could be connected to the telephone system as long as they used an acoustic coupler. Since most handsets were supplied by Western Electric and thus of a standard design, acoustic couplers were easy to build. Acoustically coupled Bell 103A-compatible 300 bit/s modems were common during the 1970s. Well-known models included the Novation CAT and the Anderson-Jacobson, the latter spun off from an in-house project at Stanford Research Institute. An lower-cost option was the Pennywhistle modem, designed to be built using parts from electronics scrap and surplus stores. In December 1972, Vadic introduced the VA3400, notable for full-duplex operation at 1,200 bit/s over the phone network. Like the 103A, it used different frequency bands for receive.
In November 1976, AT&T introduced the 212A modem to compete with Vadic. It used the lower frequency set for transmission. One could use the 212A with a 103A modem at 300 bit/s. According to Vadic, the change in frequency assignments made the 212 intentionally incompatible with acoustic coupling, thereby locking out many potential modem manufacturers. In 1977, Vadic responded with the VA3467 triple modem, an answer-only modem sold to computer center operators that supported Vadic's 1,200-bit/s mode, AT&T's 212A mode, 103A operation; the Hush-a-Phone decision applied only to mechanical connections, but the Carterfone decision of 1968, led to the FCC introducing a rule setting stringent AT&T-designed tests for electronically coupling a device to the phone lines. This opened the door to direct-connect modems that plugged directly into the phone line rather than via a handset. However, the cost of passing the tests was considerable, acoustically coupled modems remained common into the early 1980s.
The falling prices of electronics in the late 1970s led to an increasing number of direct-connect models around 1980. In spite of being directly connected, these modems were operated like their earlier acoustic versions – dialing and other phone-control operations were completed by hand, using an attached handset

Chicago metropolitan area
The Chicago metropolitan area, or Chicagoland, is the metropolitan area that includes the city of Chicago and its suburbs. With an estimated CSA population of 9.9 million people and an MSA population of 9.5 million people, it is the third largest metropolitan area in the United States. The Chicago metropolitan area is one of the world's largest and most diversified economies, with more than four million employees and generating an annual gross regional product of $680 billion in 2017; the region is home to more than 400 major corporate headquarters, including 31 in the Fortune 500. There are several definitions of the area, including the area defined by the United States Office of Management and Budget as the Chicago–Joliet–Naperville-Aurora, IL–IN–WI Metropolitan Statistical Area, the area under the jurisdiction of the Chicago Metropolitan Agency for Planning; the Chicago Metropolitan Statistical Area was designated by the United States Census Bureau in 1950. It comprised the Illinois counties of Cook, DuPage, Kane and Will, along with Lake County in Indiana.
As surrounding counties saw an increase in their population densities and the number of their residents employed within Cook County, they met Census criteria to be added to the MSA. The Chicago MSA, now defined as the Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Statistical Area, is the third largest MSA by population in the United States; the 2015 census estimate for the MSA was 9,532,569, a decline from 9,543,893 in the 2014 census estimate. This loss of population has been attributed to taxes, political issues and other factors; the Chicago MSA is further subdivided by state boundaries into the Chicago-Naperville-Joliet, IL Metropolitan Division, corresponding to the CMAP region. A breakdown of the 2009 estimated populations of the three Metropolitan Divisions of the MSA are as follows: The OMB defines a larger region as a Combined Statistical Area; the Chicago–Naperville, IL–IN–WI Combined Statistical Area combines the metropolitan areas of Chicago, Michigan City, Kankakee. This area represents the extent of the labor market pool for the entire region.
The CSA has a population of 9,928,312. The Chicago urban agglomeration, according to the United Nations World Urbanization Prospects report, lists a population of 9,545,000; the term "urban agglomeration" refers to the population contained within the contours of a contiguous territory inhabited at urban density levels. It incorporates the population in a city plus that in the surrounding area. Chicagoland is an informal name for the Chicago metropolitan area; the term Chicagoland has no official definition, the region is considered to include areas beyond the corresponding MSA, as well as portions of the greater CSA. Colonel Robert R. McCormick and publisher of the Chicago Tribune gets credit for placing the term in common use. McCormick's conception of Chicagoland stretched all the way to nearby parts of four states; the first usage was in the Tribune's July 27, 1926 front page headline, "Chicagoland's Shrines: A Tour of Discoveries", for an article by reporter James O'Donnell Bennett. He stated that Chicagoland comprised everything in a 200-mile radius in every direction and reported on many different places in the area.
The Tribune was the dominant newspaper in a vast area stretching to the west of the city, that hinterland was tied to the metropolis by rail lines and commercial links. Today, the Chicago Tribune's usage includes the city of Chicago, the rest of Cook County, eight nearby Illinois counties, the two Indiana counties of Lake and Porter. Illinois Department of Tourism literature uses Chicagoland for suburbs in Cook, Lake, DuPage and Will counties, treating the city separately; the Chicagoland Chamber of Commerce defines it as all of Cook, DuPage, Lake, McHenry, Will counties. In addition, company marketing programs such as Construction Data Company's "Chicago and Vicinity" region and the Chicago Automobile Trade Association's "Chicagoland and Northwest Indiana" advertising campaign are directed at the MSA itself, as well as LaSalle, Winnebago and Ogle counties in Illinois, in addition to Jasper, La Porte counties in Indiana and Kenosha and Walworth counties in Wisconsin, as far northeast as Berrien County, Michigan.
The region is part of the Great Lakes Megalopolis. Chicago Metropolitan Agency for Planning is an Illinois state agency responsible for transportation infrastructure, land use, long term economic development planning for the areas under its jurisdiction within Illinois; the planning area has a population of over 8 million, which includes the following locations in Illinois: The city of Chicago lies in the Chicago Plain, a flat and broad area characterized by little topographical relief. The few low hills are sand ridges. North of the Chicago Plain, steep bluffs and ravines run alongside Lake Michigan. Along the southern shore of the Chicago Plain, sand dunes run alongside the lake; the tallest dunes are found in Indiana Dunes National Park. Surrounding the low plain are bands of moraines in the south and west suburbs; these areas are hillier than the Chicago Plain. A continental divide, separating the Mississippi River watershed from that of
Palatine is a village in Cook County, United States. It is a northwestern residential suburb of Chicago; as of the 2000 census, the village had a total population of 65,479. In the 2010 census its population had risen to 68,557, making it the seventh-largest community in Cook County and the 18th-largest in the state of Illinois; the first European-American to settle in Palatine is thought to be George Ela, who built a log cabin in the area now called Deer Grove. Ela was one of the first of a wave of pioneers to migrate to northern Illinois following the Black Hawk War. A road which passes through the western edge of Palatine is called Ela Road in his honor; the Village of Palatine was founded in 1866. It was built around a station on the new North Western Railway. Joel Wood laid out the village, earning him the title of Palatine's founder. One of Palatine's original downtown streets is named after Wood. A shortline railroad, the Palatine, Lake Zurich and Wauconda Railroad, was built in 1911, began full passenger service to Wauconda, Illinois, in 1912.
The line was closed in 1924 after a series of financial misfortunes and the improvement of roads in the area. The PLZ&W provided transportation to Dr. Wilson's Deer Grove Park, just north of Dundee Road in Palatine. Palatine's first suburb-style subdivision was called Palanois Park, built shortly after World War II; the town has experienced rapid growth since part of Chicago's growing suburban sprawl. Palatine was home to the Cook County Fair from 1914 to 1931; the fairgrounds are now a subdivision with a name that pays tribute to Palatine's former fairgrounds. During the early 1990s, Palatine along with neighboring Rolling Meadows and far northern suburb Zion were sued by atheist activist Rob Sherman over its village seal and seal-defaced flag, which had a Christian cross, among other things, inside an outline of an eagle. A 1992 advisory referendum to keep the seal passed, but another referendum to use public funds to defend the seal failed, leading the village to drop the seal. While Rolling Meadows and Zion developed new seals with the crosses removed, Palatine has since been without an official seal or flag, is Illinois' largest city or village to be so.
The French tricolor reflecting the village's sister city relationship with Fontenay-le-Comte, has flown at times on the flagpole meant for the village flag outside the village hall. In 1993, a multiple homicide, the Brown's Chicken massacre, received national attention. Palatine has been in the process of revitalizing its downtown area since December 1999; this process has spawned a new passenger train station, a nearby parking garage, several new condominiums and commercial buildings. In 2008, Palatine made news by threatening to secede from Cook County over the latter's sales tax hike. In 2009, residents of Palatine Township overwhelmingly voted to pass an advisory referendum stating that they would like to secede from Cook County. According to the 2010 census, Palatine has a total area of 13.763 square miles, of which 13.62 square miles is land and 0.143 square miles is water. Palatine's shape resembles that of the head of an axe. Palatine is in a wooded marshland. Most of these streams meet up with Salt Creek.
The most notable exception is the northeast side, where its streams lie in the Buffalo Creek watershed. A small part of the east and southeast sides lies in the McDonald Creek watershed; as of the 2010 census, there were 68,557 people, 26,876 households, 17,646 families residing in the village. The racial makeup of the village was 76.9% White, 2.7% African American, 0.3% Native American, 10.3% Asian, 0.03% Pacific Islander, 7.4% some other race, 2.3% from two or more races. Hispanic or Latino of any race were 18.0% of the population. There were 26,876 households out of which 33.2% had any child under the age of 18 living with them, 52.8% were headed by husband-wife couples, 9.0% had a female householder with no husband present, 3.8% had a male householder with no wife present, 34.3% were non-families. 27.8% of all households were made up of individuals living alone, 7.5% were someone living alone, 65 years of age or older. The average household size was 2.54, the average family size was 3.16.
In the village, the population was spread out with 23.9% under the age of 18, 7.5% from 18 to 24, 30.6% from 25 to 44, 27.3% from 45 to 64, 10.5% who were 65 years of age or older. The median age was 36.8 years. Of the total population, 49.4% were male and 50.6% were female. According to the 2011 American Community Survey, the estimated median income for a household in the village was $63,756, the median income for a family was $74,915; the per capita income for the village was $30,049. About 8.2% of families and 9.9% of the population were below the poverty line, including 14.4% of those under age 18 and 4.3% of those age 65 or over. The village is home to a large Sikh gurdwara on its northwest side, visited by Sikhs from across the country. Palatine operates under the Council-manager form of local government. Six councilmen are elected from their respective districts, while the entire village elects the Village Clerk and the Mayor; the council hires a Village Manager to oversee the town's day-to-day operation.
The current mayor is Jim Schwantz. Weber-Stephen Products, manufacturer of the Weber grill, is headquartered in Palatine. According to Palatine's 2017 Comprehensive Annual Financial Report, the top employers in the city are: Palatine is part of Community Consolidated School District 15 f
Itasca is a village in DuPage County, United States. It is located 27 miles northwest of downtown Chicago, it is close to O'Hare International Airport, major expressways, rail transportation. The population was 8,649 at the 2010 census. In 2009, BusinessWeek rated Itasca as the'Best Affordable Suburb' in the state of Illinois. Itasca was first settled by Elijah Smith in 1841. Smith practiced medicine in Boston. In May 1841, at the advice of his colleagues he set out to find a suitable site for doctoring and raising a family, he headed toward DuPage County. His parchment government land title dated March 10, 1843, was signed by John Tyler, President of the United States; the document gave Smith title to the land, now bounded by the railroad tracks on the south, Maple Street on the west, Cherry Street on the east, Division Street on the north. The post office was established in 1846 and took on various names, such as Bremen and Sagon; the name Itasca comes from Lake Itasca. In the 1860s the first school was built.
It was a small wooden structure with one room. The building was located on a site near the present First Presbyterian Church. In 1873 Smith plotted eighty acres of his land into lots; the Chicago and Pacific Railroad was completed from Chicago to Elgin, with stations at Bensenville, Wood Dale and Itasca. Smith gave the right-of-way to encourage location of the tracks through the settlement, he donated $400 to help build a station. The Chicago and Pacific Railroad became "insolvent," as bankruptcy was termed. In 1880 the road went into the hands of the Chicago, Milwaukee, St. Paul and Pacific Railroad, a newly formed corporation combining several rail networks; the citizens of Itasca decided in 1890 to incorporate into a village. At a meeting at his mill, A. G. Chessman was elected the first Village President. Irving Park Road was first called the Elgin Road. At an 1891 Village Board meeting, the name was changed to Elgin Avenue; the 1900s The Village of Itasca created a Historical Commission in 1985 to retain the aesthetic beauty and historical integrity of the Village.
The Village of Itasca is committed to the preservation of its pre-1900 and early 1900 homes, buildings and places. In 1987, the Village adopted the Historic Preservation Ordinance which provides a mechanism to identify and preserve the special distinctive historic, architectural and/or landscaping characteristics of the Village's cultural, economic and architectural history; the Itasca Historical District includes the following area: Bounded on the north by North Street, on the south by Bloomingdale Road, east to Irving Park, Irving Park east to Rush Street. The Spire, Itasca's most familiar landmark, graces the top of what was the Lutheran Church of St. Luke; this edifice was erected in 1907 by builder Fred Westendorf. Pastor Frederick Zersen served the congregation for thirty-eight years. Church services were in German, it was not until 1926. German was taught in the church school; until 1916, there was no bank in Itasca. Herman H. Franzen took deposits for Village residents to the Roselle Bank each morning, making the trip on the 9:00 AM train.
In 1916, two banks opened within weeks of each other. The Itasca State Bank had as its president H. F. Lawrence; the cashier was Elmer H. Franzen; the second bank was called the Dairyman's Bank of Northern Illinois, was opened by F. N. Peck. Peck opened a total of four banks; the Franzen banks in Itasca and Fox Lake were sound throughout the hard times of the 1920s, emerged from the Depression. Telephone service had come to Itasca in 1899. Electricity was first installed in some homes in 1923; the bustling community soon gained another facility. The Itasca Country Club was opened in the spring of 1925; the rural village of the 1800s and early 1900s retained its atmosphere until the 1940s. A new word began to enter the American vocabulary: suburb; the influence of the city increased. Commuting daily to the Loop became the routine for many of the Village wage earners. By 1982, the population had grown to 7,192. Annexations had resulted in fifty miles of Village streets, more parks, two industrial areas to serve.
Providing safety and service as population increased required the establishment of departments of public works, of sewer and water, of building and police. A park district, a Village library, a fire district were formed. High school students from Itasca attended Bensenville's Fenton High School and Glenbard High School, a combined Glen Ellyn-Lombard school. A high school district, District 108, was organized in 1953. Lake Park High School, with students from Itasca, Medinah and Bloomingdale, opened in September 1956. Modern industry was foreign to Itasca until 1961 when Central Manufacturing District bought about 400 acres on the western edge of the village. An industrial park was established, such national companies as Continental Can and FMC soon moved in. In 1970, the Itasca Industrial Park was established to the east of the Village, attracted many more industries. Anvan Corporation built a Holiday Inn on Irving Park east of Route 53; the building was of modular construction, the first such hotel in the nation to be built in this manner.
In 1969, Carson Pirie Scott purchased Nordic Hills Country Club. Two 10-story tower hotel buil
