Computer Network Basics

What is a Computer Network?
Computer networks can be interpreted as 2 or more autonomous computers that are connected to one another through network communication media, to share information, data and also existing resources.

The main purpose of a computer network is sharing resources (read: resources), where a computer can utilize the resources owned by other computers that are in the same network.
The development of computer data and network communication technology today is no longer limited to computers. Various communication technology devices that are present are currently developing in line with the development of computer technology, many of which integrate computer devices such as microprocessors, memory displays, storage, and communication technology into them even though this technology was developed for computers that we can currently use in technology computer network.

A computer network consists of:

– minimum of two computers
– network card (network interface card / NIC) on each computer
-medium connection, which connects one computer’s network card to another computer, commonly referred to as a data transmission medium, can be either wired or wireless or wireless (wireless such as radio, microwave, satellite, etc.).
– Network operating system software (NOSS) which functions to manage network systems, for example: Microsoft Windows 2000 server, Microsoft Windows NT, Novell Netware, Linux, and so on.
– interconnection equipment such as Hubs, Bridges, Switches, Routers, Gateways, if the network is formed the wider the range

• Source. This device has the duty to generate or determine the data to be transmitted; for example a telephone or personal computer.
• Transmitter. Usually, data is generated by the source system and is not directly transmitted directly in the form as the data was created. A transmitter will transform and encode the information in the form of electromagnetic signals that can be propagated on the transmission system. For example, a modem takes a bit stream from a computer and transforms it into analog signals that can be propagated on the telephone network.
• Transmission System. This can be in the form of transmission media or communication lines or a complex network that connects source and destination.
• Receiver. The receiver receives signals from the transmission system and converts them into a form recognized by the destination device. For example, a modem will receive analog signals coming from a network or transmission line and convert them into digital streams.
• Destination. Is the final goal of sending data that receives data from the receiver.

How is the Data Communicated?

The picture above is another perspective of the data communication model (figure a). To facilitate understanding, we take the example of sending electronic mail.
Suppose the input and transmitter devices are components of a personal computer (PC). A user on a PC will send a message to another user. This user will activate the electronic mail package on the PC and type messages through the keyboard (input device). The character string created will be stored in the main memory buffer. This PC is connected to a transmission medium,

The Importance Of Learning Information Technology


Learning Information Technology in this day and age is very important, because nowadays most of them use information technology tools. Learning information technology is very beneficial, where we can use it in everything. With Information Technology we can know a lot of things that we don’t know. Technology develops very fast. One area that has a significant impact on technological developments is in the field of education.

During the three semesters, I got a lot of knowledge. began to study networks, databases to get to know the Website to operate it. Now I am getting used to information technology tools.
Now I know that everything can be done with internet networks. For example Facebook. I often use Facebook, because there I can communicate with friends, family, teachers and lecturers. In addition to communication, I can use the internet network to look for sources, and other things. Lots of people who use internet networks.


Using the internet network nowadays can be done anywhere, because there is already a hotspot, in addition to internet network hotspots can also be obtained by using a modem.
Apart from the above, I also learned about the history of computers, the internet and other things. That is very important, because besides just using it, I also have to know its history. Besides Facebook, I also learned about blogspot. Blogs are an easy way to recognize someone’s Blogger personality. In the blog I can write about what I want, because on blogs also reveal about a person’s personality.


Before creating facebook and blog, the first condition is that we must have e-mail. E-mail is very important, because by e-mail I can do many things, such as creating facebook, and many other things that use e-mail.
In addition to the internet, I can also find out about the media that are currently being used by the public. Laptops and notebooks are one example that is currently being used by many people. Laptops and notebooks are very practical, so they can be taken anywhere. Besides laptops and notebooks, the contents are complete.


Actually we have used information technology since ancient times, only the forms and methods are different, while the intent and purpose are the same. Maybe in the past it wasn’t so sophisticated, so there were limitations. Everyone must know about information technology.
The things above are some of my knowledge after learning information technology. Learning information technology is very fun and easy to understand, so I can quickly understand and immediately practice it.

Journal Of Drug Delivery Science And Expertise

science and technologySince its involvement in promoting international reflection on the ethics of life sciences within the Nineteen Seventies, UNESCO continues to construct and reinforce linkages amongst ethicists, scientists, coverage-makers, judges, journalists, and civil society to help Member States in enacting sound and reasoned policies on moral issues in science and expertise. Please word that all new submissions to Measurement Science and Know-how require an announcement (in below 100 phrases) detailing the novelty, significance and broader relevance of your work in a measurement context. You observe the teacher coaching programme at a higher tutorial degree at the Saxion College of Applied Sciences and the Grasp’s programme Academic Science and Expertise at the University of Twente.

Also contributing to the intensification of the competition is world climate change (about which extra will be stated below), which is sharply increasing the demand for both biofuels and carbon sequestration in intact forests ( 15 ) similtaneously it stresses farms and forests in lots of parts of the world with increased warmth, drought, and wildfires ( 16 ).

An author order form for reprints, additional journal copies or a pdf file will likely be despatched to you along with the pdf proof. British photographers Fiona Rogers and Anup Shah captured apes in Indonesia and Borneo – and highlighted how human our evolutionary cousins are. Advances in know-how help meet primary human wants and drive financial growth via increased productivity, diminished costs, diminished useful resource use and environmental affect, and new or improved services. The United States Observe & Field and Cross Nation Coaches Association ranked A&T men’s monitor and area workforce among the many prime-25 in program history. It covers all aspects of the idea, follow and application of measurement, instrumentation and sensing throughout science and engineering.

Personal-sector investments in ERD&D are much more difficult to estimate; but, if following the final sample within the United States they’re assumed to be twice authorities investments, then the general public/non-public total for the world is in the vary of $35 billion to $50 billion per yr, which is equal to at most 1{a6333948396c60ea226bcf4d62ea2c1776162caffcbc12ef4a2c4883cd483011} of what’s spent on vitality itself.

The endeavor related to the establishment and the growth of the journal is predicted to lend support to the renaissance of nuclear technology on the earth and particularly in these international locations where nuclear packages have not but been developed. The Academic Science and Technology programme focuses on the design and evaluation of instructing and learning programmes in colleges and organizations.

Know-how Sector

definition of technologyThe definition of expertise is science or knowledge put into sensible use to solve issues or invent helpful instruments. On this info age, it is rather necessary to manage data systems to ensure accuracy and effectivity. Know-how is used to construct theaters, it is used to create video video games, to develop musical programs and so much extra. There could be no efficient persuasion or ideology with out success in definition first. Through a concept known as adequacy ( Garson 2013 ) we might obtain our definition. After shopping for and integrating technology in enterprise, you will have to pay another value of maintaining that expertise, monthly maintenance is recommended and this can be expensive. To view samples of technology training course constructions, see the record of related hyperlinks below.

Increases manufacturing: Expertise helps companies automate most duties and this course of outcomes into increased production and effectivity. Conversely, for completeness, it should be shown that valid instances of expertise are those for which we may provide proof.

Information workers in group use information technology to complete varied duties and these can embrace; transferring of information which facilitates choice making with in an organization, enhance customer service, and a lot more. It was for that reason that I completely understood the remarks in the literature by those that expressed a way of pessimism concerning the process of definition with respect to know-how particularly, or the method as a complete on the whole. They also offer a Hybrid Course Growth Institute for college trying to replace some face-to-face instruction with increased online educating. As you may see within the picture above, if technology is well carried out it may be of great use to humanity, but it may also cause hurt. That however, as our values remodel, so does our perception of the technology that led to the change.

In conclusion, judging from the four steps of fixing a problem utilizing technology, you will notice that the technology we’re utilizing began with an idea of solving an issue or meeting an opportunity. Volti’s definition does not permit for such examples of technology to be considered, nor do any of these we thought-about from the literature. As an example, Pitt ( 2000 ) outlined technology simply as humanity at work,” whereas Johnson ( 2006 ) has argued what Anderson and Anderson ( 2011 ) have equally echoed: expertise is the thought of things which can be created or human-made. A dedication of dimensions comprising know-how was made by critiquing historic and modern examples of definition by Bigelow and Volti. Definitions, uses, and understanding of expertise have diversified tremendously since Jacob Bigelow’s Elements of Expertise in 1829. Beneath I’ve detailed factors on the advantage and disadvantage of technology in business, classroom or education.

Taken collectively, both soundness and completeness comprise the notion of adequacy, which as a condition is happy, when the definition, as a check, appropriately identifies expertise, if, and provided that, that technology is a sound example. Definitions counting on an … Read More
