Practice Activity 1. Voice vs Data

Cell Phone: Today’s cell phones have capacity to transmit and receive data as well as voice
Landline Phones: As advanced as many technologies are today landline phones primary function is still to transmit and receive audio (voice) from one end to another.
SMS/Text Messaging: is used to transmit and receive data only.
Fax Machines: is used to transmit and receive data only.
Pagers: is used to transmit and receive data only.
VOIP Phones: uses both voice and data networks to send and receive data
Skype/Facetime: uses both voice and data networks to send and receive data

Practice Activity 2: Local Exchange:
When you start your PC and log into an online game your PC takes a long journey to the gaming center, your fellow players make the same journey to the same game server. The journey starts with your PC getting online through your LAN passing through your switch via CAT5 cable onto the WAN (wide area network) generally with Fiber Optic cable. It then passes through a Central Office with your ISP and onto the gaming center office where it enters through their switch onto their routers and servers. This happens on a broader spectrum connecting many “gamers” together to provide the online gaming experience.

Activity 1 Data and Fixed line VS Cellular debate

Fixed line networks can be more reliable than cellular. Disconnected cables can disable land lines, but these problems are easily remedied. On the other hand, cellular networks are plagued by several different issues because they rely on a network cellular towers and satellites. In some areas, cellular networks can be plagued by harsh weather conditions.
Because data is transmitted via a fixed medium, land line phones are more secure than cell phones. Cellular networks are more susceptible to hackers and viruses because users can bring in or download…...

...1. Introduction The telecommunications sector in Malaysia has undergone significant physical and structural transformation in the past fifteen years. Between 1985 and 2000, the country’s telephone penetration rate rose by 540 per cent. Equally importantly, privatization and liberalization of the sector in the 1980s ushered in an era of regulatory reforms and competition in the sector. The market structure as well as the regulatory framework and institutions for the telecommunications sector continue to evolve. The real challenge lies in what to do after that – putting in place adequate regulatory framework and institutions that will ensure industry growth as well as protect consumer welfare. The on-going micro-regulatory reforms in the sector seek to fine-tune the regulatory mechanisms in the sector. This paper reviews the recent history and development of the telecommunications sector in Malaysia. Section 2 provides a brief historical account of the sector and the current structure of the sector. This is followed by a discussion on regulatory reforms in Section 3. Section 4 examines the impact of reforms in the telecommunications sector. Section 5 concludes by discussing the future policy agenda for the sector. 2. EVOLUTION OF INDUSTRY STRUCTURE 2.1.

...TELECOMMUNICATIONS Telecommunication is communication at a distance by technological means, particularly through electrical signals or electromagnetic waves. Due to the many different technologies involved, the word is often used in a plural form, as telecommunications. Early telecommunication technologies included visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs. Other examples of pre-modern telecommunications include audio messages such as coded drumbeats, lung-blown horns, and loud whistles. Electrical and electromagnetic telecommunication technologies include telegraph, telephone, and teleprinter, networks, radio, microwave transmission, fiber optics, communications satellites and the Internet. A revolution in wireless telecommunications began in the 1900s with pioneering developments in radio communications by Guglielmo Marconi. Marconi won the Nobel Prize in Physics in 1909 for his efforts. Other highly notable pioneering inventors and developers in the field of electrical and electronic telecommunications include Charles Wheatstone and Samuel Morse (telegraph), Alexander Graham Bell (telephone), Edwin Armstrong, and Lee de Forest (radio), as well as John Logie Baird and Philo Farnsworth (television).

In order to get a background which will help when developing the new system, your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor , the Telecommunications Manager, within a week. 1. Describe a local land line phone system based on the following Landline Telephone Components: a. Local Loop a local loop is the wired connection from a telephone company's central office in a locality to its customers' telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL), the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only. b. Central Office In telephone communication in the United States, a central office (CO) is an office in a......

... ULTRASOUND TRANSMISSION AND NETWORKING SYSTEM IN A HOSPITAL NAME: INSTITUTION: Introduction Ultrasound is sound frequencies waves with which are normally higher than those audible to human beings; Ultrasound is used in navigational, electronic, industrial, and also security applications. It is also used in medicine to view internal part/organs of the body of a human being such as muscles, joints, tendons, vessels and internal organs. Its aim is often to exclude any pathology or to find a source of a disease. The practice of examining pregnant women using ultrasound is called obstetric ultrasound and is widely used. Ultrasound machines will differ basing on the features that they mainly offer, (Dion, et al 2002) . The features may comprise freezing an image, image storage, standby mode in saving battery power and ergonomic design, and also water and dust resistance, even oil resistance. There will also be a variety of weights and sizes, ease of use, workflow, durability and service. In the hospital setup, transmitting ultrasound images from the ICU to the main hospital, the outpatient and other relevant hospital departments will entirely depend on the size of the hospital/clinic, some technicians, quality, and versatility of images and videos and storage expected. High-quality ultrasound machines will, therefore, give quality images, videos and any scanned document hence making easing the work and offering quality services while meeting the hospital goals.
