BlueTooth Technology by Jith Crs
Bluetooth is the name given to a new technology standard using short-range radio links, intended to replace the cable(s) connecting portable and fixed electronic devices. The standard defines a uniform structure for a wide range of devices to communicate with each other. ... Telephony and Cable Replacement Protocol: Telephony Control protocol: Binary (TCS Binary or TCS BIN), a bit oriented protocol, defines the call control signaling for the establishment of speech and data calls between Bluetooth devices.

File Transfer Protocols by Alison Cole
File Transfer Protocol is a protocol that is used for exchanging files within a network that supports the transmission control protocol/Internet protocol (TCIP/IP)—protocol or protocols used in the Internet and Intranet. In a file transfer, two computers are involved; the first computer is an... This is accomplished when a program is written by a supplier company that automatically transfers data from his computer to the computers of his partners every time there is movement in his stocks to keep his inventory up to date.

Introduction Of Computer by Lalit Bansal
Internet and Networks Computer network is a group of computers linked together, so that they can share information and resources. Internet is “network of networks”. It can also be described as information highway. It is the world’s largest network of computers. ... TCP/IP: TCP (Transmission Control Protocol) and IP (Internet Protocol) are the two types of protocol. ... The first one TCP (Transmission Control Protocol) is a reliable, connection –oriented protocol that allows stream of bytes from the sender to be delivered to the receiver without error.

Back To The Basics: Communication Devices by Deb Jensen
Since today's communication technology can be confusing for many people, Genesis Global, Inc. wants to go back to the basics and take a brief look at the various types of communication channels available. This article addresses eight basic factors which affect data transmission: "transmission... That is, a "start" bit represents the beginning of a character, and a "stop" bit represents its end." Synchronous: (timed transmission) "Instead of using start and stop bits, synchronous transmission sends data in blocks.

High Speed Downlink Packet Access by Riktesh Srivastava
The Technology As we saw, the 3.5 G standard used in HSDPA is an improvement upon the 3G protocol used in W-CDMA technology. With HADPA, the data transfer rate improves over W-CDMA by a factor of at least five. Theoretically speaking, it is possible to reach data transmission speeds of 8-10... Here, the retransmissions have different codes of the data against the codes of the original transmission. ... In other words, the data received at the base station is ‘processed’ to manage any corruption the data may have gone through at the time of the original transmission.

OSI Layers Model by Kashif Raza
Introduction During the early years of our modern computer era, very few standards and protocols existed between various manufacturers. However, as time went on and computer technology continued to improve and become more widespread, it became apparent that standards would be necessary to... An example protocol at this layer is the Transmission Control Protocol (TCP). ... The data link layer consists of two sub layers; the logical link control (LLC) and the media access control (MAC), which provide reliable communications by ensuring the data link is not broken and also by examining...

History of the Computer - Data Handling Peripherals; Part 3 of 3 by Tony Stockill
TELETYPE MACHINES Developed for telegraph 'hard copy' communication over the telephone network, a teletype machine was suited to adoption by the rapidly expanding computer market, with its demand for hardware and technology to run it. A ready-made printer and keyboard communication device, it... Ethernet also increased from 10 to 100 to gigabit transmission rates. ... Others incorporate all functions in one control, with auxiliary stations in the print room, network console, etc. ... (you still can't get away with anything!)

The Evolution of CCTV Technology by John Beagle
Each camera had its own monitor. CCTV systems were introduced progressively throughout the 1960s and 70s. New applications of camera security systems included underground trains and stations, football stadium, retail stores, shopping centers, public housing, community parks, garages and parking... With such flexible access, the modern generation of CCTV cameras may be operated remotely from a control center or, in fact anywhere with internet access. ... Using DVRs using IP (Internet Protocol) technology, allow cameras to be controlled over a local area network (LAN), a wide area network...

Internet Privacy by Greg Johnston
The World Wide Web, aka the Internet, consists of interconnected computer systems and networks. These systems and networks communicate via Transmission Control Protocol / Internet Protocol, referred to as TCP/IP, in order to transfer data and process information. ... Lock up by taking security measures both online and off. ... Password Protection Roboform Password Agent So arm your equipment, yourself and your family. ... If you need help with all the online tools out there today, start by checking to see what’s available already on your computer and with your Internet service provider,...

Wireless Network Encryption Standards by Eric Meyer
WEP – Is the first and lowest standard for wireless security. You will hear security experts say that WEP can be cracked in 5 minutes; this is true, only once you have sniffed enough network traffic for weak IV’s. Collecting enough wireless traffic will take at least a couple hours under... If you are using a RAIDUS server you have complete control over who enters your wireless network. ... If your PSK is leaked to the wrong person or stolen somehow, you don’t have any control of who is accessing your network.
