Different Types Of Data Communication Media

April 23, 2017

The process in which data is transferred from one computer to another is known as communication media. Data communication involves transmission of digital of information to different electronic devices through wireless or cabled connections. The two commonly used computer communication media used are bounded and unbounded media.A. Bound MediaData transfer through physical connections is referred to as bounded media in that signals are sent to other external devices from one computer in a network. Computers can be interconnected to share files and devices in a network by means of cabling which facilitates faster communication of information. Bounded media is a faster data communication that provides high speed transfer of signals over long distances and is the most reliable media for message sending.Bounded media is categorized into three types of data communication which enables connection of different types of network. These cables include:

1. Coaxial cableThis is most common bounded media that is many electronics to transfer data and it is designed with two parallel copper conductors. It has a solid central copper conductor that transmits signal and is coated with a protective cover to reduce electromagnetic interference. Coaxial cable is found in different gauges at affordable prices and is easier to work with. They are easy to install and can support up to 10Mps capacity with medium attenuation. Despite its popularity, the only serious drawback it has is that the entire network is always affected with a single cable failure.2. Twisted pair cableTwisted pair cables are found in two types and these include unshielded and shielded twisted pair cables. It is commonly used because it is lighter and inexpensive. They are made up of twisted solid copper wires which help to reduce vulnerability to EMI and cross talk effects. This type of cables is cheaper and can support up to 100mps speed capacity.3. Fiber opticUnlike other types of cables, fiber optic uses electrical signals for communication and is made up of reflective cladding that prevents loss of light in the glass core. Although it very expensive and hard to install, optic cables can support at least 2gbps and are not vulnerable to EMI interference. It has got also very fast data transmission and very low attenuation compared to other data cables.B. Unbounded mediaThis type of data communication media involves networking of multiple computers through a wireless connection. Creating a wireless connection is much easier since no physical connection is required and can connect multiple computers in a room. Unbounded media uses space or air as the transmission medium for electronic waves. Some of the unbounded media are the satellites, radio, Bluetooth and Wi-Fi among others. Installation of wireless network is much easier and faster compared to the bounded media which require an expert to do the configuration. Through wireless settings, you can also transfer huge files of data to any networked computer since the unbounded media supports very high bandwidths just like the cabled network.

Generally, in order to transmit data over networked computers, you will have to use either bounded or unbounded types of media. Depending on the type of network you want to create, convenient type of media is required to enable consisted and proper data communication.

Five Similarities Between Religion and Spirituality

April 23, 2017

When we were children we were asked, Which came first, the chicken or the egg? If we based our answer on the creation story in the Bible, we would answer, Chicken. But if we based our answer on our experience in raising chickens, our answer would be, Egg.The same can be said of the answer to the question, Which came first, Religion or Spirituality?In terms of our experience with religious books and discussions, religion came first. It is only now that more and more people are talking about spirituality and writing about it. In terms of the origin of the reality behind those words or in terms of the object of our understanding, spirituality came first. The spirit was there before there was any religion. God was there before there was anybody to worship him.We can even say that spirituality is an offshoot of religion. For many centuries people professed religion. Some of them fiercely opposed religions other their own. Christians for many centuries opposed paganism, Islam, Hinduism, Buddhism, and any other religion. This has happened also with paganism, Islam, and the rest with respect to the other religions. They too opposed other religions.

But more and more people discover that mere religion cannot answer their deeper yearning for a better experience of life. So, they turned to something deeper and better than religion. They found this in spirituality.Because spirituality in a sense is an offshoot of religion, there is bound to be some similarity between them, just like the similarity between the egg and the chicken.First, both believe in a higher power of some kind. Religion believes in God the Father or Jesus, or Allah, or Brahman, or Tao. Spirituality believes also in this God or it may conceive of God as a universal or primal energy. Both believe that such being possesses power higher and greater than what we have.Secondly, both religion and spirituality desire to have a relationship with this higher power. Although the nature of the relationship is different in religion than in spirituality, the desire for this relationship is there. Religion connects with this higher power with fear and trembling. Spirituality connects with this higher power with love and affection.Thirdly, both religion and spirituality have rituals and practices which deepen one’s religiosity or spirituality. Religion usually has sacred rites or sacraments. Spirituality has meditation or yoga sessions.

Fourthly, both have respect for the sacred, the other worldly. This is not just respect for God. This is respect for the reality that is beyond our senses and reason. When religion pushes this respect to its extreme, it becomes superstition. When spirituality pushes this respect to its extreme, it becomes religious spirituality.Fifthly, both have fear of failure. In religion this failure is punished by hell fire or repetition of existence or some other worse fate. In spirituality this failure is the inability to realize one’s true worth or value and the destiny of a life of meaninglessness. Hell, repetition of existence, non-existence, meaninglessness are forms of punishment for failure, either in religion or in spirituality.
