Carbon Copy (software)
Carbon Copy was "a remote control/communications program" with for-its-day advanced features for remote screen sharing, background file transfer, and "movable chat windows". Overview The ''New York Times'' described it thus: "you can sit at the console of either machine and call up the programs and files stored on the other". ''Computerworld'' called it "a package that mirrors every action a user takes on two connected PCs". Part of its user base was acquired via inclusion as bonus software for a modem that could communicate at "300, 1200 and 2400 baud." Carbon Copy's vendor, Meridian Technology, was acquired by Microcom in early 1988, and accepted tax credits to move software duplication and packaging of ''Carbon Copy'' to Puerto Rico. Meridian had a British subsidiary, also acquired by Microcom. History ''Computerworld'' covered the flow of features and newer releases: 3.0 (1986), 1987, 1989. By 1991, although Version 5.2.2 was still actively marketed, Version 6.0 was release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File Transfer
File transfer is the transmission of a computer file through a communication channel from one computer system to another. Typically, file transfer is mediated by a communications protocol. In the history of computing, numerous file transfer protocols have been designed for different contexts. Protocols A file transfer protocol is a convention that describes how to transfer files between two computing endpoints. As well as the stream of bits from a file stored as a single unit in a file system, some may also send relevant metadata such as the filename, file size and timestamp - and even file system permissions and file attributes. Some examples: * FTP is an older cross-platform file transfer protocol * SSH File Transfer Protocol a file transfer protocol secured by the Secure Shell (SSH) protocol * Secure copy (''scp'') is based on the Secure Shell (SSH) protocol * HTTP can support file transfer * Bittorrent, Gnutella and other distributed file transfers systems use peer-to-peer * ...

Computerworld
''Computerworld'' (abbreviated as CW) is an ongoing decades old professional publication which in 2014 "went digital." Its audience is information technology (IT) and business technology professionals, and is available via a publication website and as a digital magazine. As a printed weekly during the 1970s and into the 1980s, ''Computerworld'' was the leading trade publication in the data processing industry. Indeed, based on circulation and revenue it was one of the most successful trade publications in any industry. Later in the 1980s it began to lose its dominant position. It is published in many countries around the world under the same or similar names. Each country's version of ''Computerworld'' includes original content and is managed independently. The parent company of Computerworld US is IDG Communications. History The first issue was published in 1967.

Modem
A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by Modulation#Digital modulation methods, modulating one or more carrier wave signals to encode digital information, while the receiver Demodulation, demodulates the signal to recreate the original digital information. The goal is to produce a Signal (electronics), signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio. Early modems were devices that used audible sounds suitable for transmission over traditional telephone systems and leased lines. These generally operated at 110 or 300 bits per second (bit/s), and the connection between devices was normally manual, using an attached telephone handset. By the 1970s, higher speeds of 1,200 and 2,400 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
300 Baud
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. The distinction can be arbitrary between a ''computer bus'', often closer in space, and larger telecommunications networks. Many device interfaces or protocols (e.g., SATA, USB, SAS, PCIe) are used both inside many-device boxes, such as a PC, and one-device-boxes, such as a hard drive enclosure. Accordingly, this page lists both the internal ribbon and external communications cable standards together in one sortable table. Factors limiting actual performance, criteria for real decisions Most of the listed rates are theoretical maximum throughput measures; in practice, the actual effective throughput is almost inevitably lower in proportion to the load from other devices (network/bus contention), physical or temporal distances, and other overhead in data li ...

Hewlett-Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components, as well as software and related services to consumers, small and medium-sized businesses ( SMBs), and large enterprises, including customers in the government, health, and education sectors. The company was founded in a one-car garage in Palo Alto by Bill Hewlett and David Packard in 1939, and initially produced a line of electronic test and measurement equipment. The HP Garage at 367 Addison Avenue is now designated an official California Historical Landmark, and is marked with a plaque calling it the "Birthplace of 'Silicon Valley'". The company won its first big contract in 1938 to provide test and measurement instruments for Walt Disney's production of the animated film ''Fantasia'', which allowed Hewlett and Packard to formally esta ...

Microcom
Microcom, Inc., was a major modem vendor during the 1980s, although never as popular as the "big three", Hayes, U.S. Robotics (USR) and Telebit. Nevertheless, Microcom holds an important place in modem history for introducing the MNP error-correction and compression protocols, which were widely used under license by most modem manufacturers in the 1990s. The company went public in 1987. Compaq purchased publicly outstanding shares of the company in 1997. History and products Microcom was founded in 1980 by James M. Dow from Data General. In the mid-1980s several companies introduced new modems with various "high-speed" features in order to differentiate themselves from the growing legion of Hayes 1200 bit/s clones that were flooding into the market. Developing such a protocol was not all that easy, and generally required a fairly powerful and expensive microcontroller to handle the modulation. For companies with limited resources, entering this market was difficult. Micr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BLAST (protocol)
BLAST (BLocked ASynchronous Transmission), like XMODEM and Kermit, is a communications protocol designed for file transfer over asynchronous communication ports and dial-up modems that achieved a significant degree of popularity during the 1980s. Reflecting its status as a de facto standard for such transfers, BLAST, along with XMODEM, was briefly under official consideration by ANSI in the mid-80s as part of that organization's ultimately futile attempt to establish a single de jure standard. Overview BLAST grew out of the mission-critical experience of providing air pollution telemetry within the dial-up communications environment of the petroleum belt of southern Louisiana and Texas, with not only noisy telephone lines but also unexpected satellite hops to remote locations.Smith, G.

Kermit (protocol)
Kermit is a computer file transfer/management protocol and a set of communications software tools primarily used in the early years of personal computing in the 1980s. It provides a consistent approach to file transfer, terminal emulation, script programming, and character set conversion across many different computer hardware and operating system platforms. Technical The Kermit protocol supports text and binary file transfers on both full-duplex and half-duplex 8-bit and 7-bit serial connections in a system- and medium-independent fashion, and is implemented on hundreds of different computer and operating system platforms. On full-duplex connections, a sliding window protocol is used with selective retransmission which provides excellent performance and error recovery characteristics. On 7-bit connections, locking shifts provide efficient transfer of 8-bit data. When properly implemented, as in the Columbia University Kermit Software collection, its authors claim performance i ...

History Of Software
Software is a set of programmed instructions stored in the memory of stored-program digital computers for execution by the processor. Software is a recent development in human history, and it is fundamental to the Information Age. Ada Lovelace's programs for Charles Babbage's Analytical Engine in the 19th century is often considered the founder of the discipline, though the mathematician's efforts remained theoretical only, as the technology of Lovelace and Babbage's day proved insufficient to build his computer. Alan Turing is credited with being the first person to come up with a theory for software in 1935, which led to the two academic fields of computer science and software engineering. The first generation of software for early stored-program digital computers in the late 1940s had its instructions written directly in binary code, generally written for mainframe computers. Later, the development of modern programming languages alongside the advancement of the home compute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
