HISTORY OF COMPUTER NETWORKS

    The concept of computer network born in the 1940s in America of a development project in the laboratory computer MODEL I Bell and Harvard University research group led by professor H. Aiken. At first the project was to utilize a computer device that must be used together. To do some of the process without much waste of time was made vacant succession process (batch processing), so some programs can run on a computer with the rules of the queue.

    Ditahun 1950s when the types of computers began to swell up to the creation of a super computer, a computer must serve several terminals (see Figure 1) For that discovered the concept of distribution of time-based process known as TSS (Time Sharing System), for the first time form network (network) computer application. In the TSS system several terminals connected in series to a host computer. In the process of TSS began to seem a mix of computer technology and telecommunication technology that was originally developed on their own.

    Entering the 1970s, after much work load increased and the price of computers began to seem very expensive, then start to use the concept of the distribution process (Distributed Processing). As in Figure 2, in this process some of the host computer to do a great job in parallel to serve several terminals are connected in series in each host computer. Dala distribution process is absolutely necessary in-depth blend of computer and telecommunications technology, because in addition to the process that must be distributed, all must serve the host computer terminals in a single command from the central computer.

    Furthermore, when the small computer prices have started to decline and the concept of the distribution process has matured, then the use of computers and networks have started a variety of start dealing with the process and communication between computers (Peer to Peer System) alone without going through a central computer. For that began developing the local network technology known as the LAN. Similarly, when the Internet was introduced, the majority of stand-alone LAN began an association and forming a giant network WAN.

Community College Education A good start

Many people seek and find they will attend the University after graduating from high school. Students look forward to their time at university while parents squeeze their hands hoping that their children choose to attend a university that is not only close to home but also within their budget constraints. worries parents when their child decides to attend college is whether or not that the university they attend will have a special service and individual children they were accustomed to receiving in high school. Larger universities tend to be impersonal when it comes to the education of their students. 

One answer to all concerns that more is to transition students from high school to college two years instead of throwing them into the university serigala.Banyak people found that two-year college could actually provide a superior education to four-year university for the first year or two basic-level college programs. You will not get certain special instructions or in a two-year colleges are available for upper level students at the university level, but most students find the first two years of college education they focused on getting the pre-program needs and requirements rather than specific programs within the field their study is intended. 

Many people also find that the first two years at a community transition from college-a small pond to a larger lake-are much easier to handle than going straight from high school to university-out of the pool and the sea. Universities often have a lower level classes as auditorium classes. These classes offer instruction individually small and often sink or swim kind of class. Those students who have special learning needs are often lost in the shuffle when entering the university. Community colleges offer smaller classes and extensive opportunities for tutoring and classes on how to learn to learn. 

Two-year colleges are also easier on the budget than most universities. Most people find that the college does not put nearly the financial burden on families where the university. Add to the fact that most community colleges offer very flexible scheduling classes and even some online courses and you will find that there are many reasons to consider a community college that will go beyond mere budgeting requirements. 

Another benefit for students who wish to enter the workforce sooner rather than later is that you really can get a degree or certification in a particular program from a two-year college. This means that you can actually graduate and start earning more quickly than if you attend four-year college to seek a degree. If you are not sure you want to invest four or five years ahead of your life in pursuit of a degree or you're just not ready to commit yourself to one line of work for the rest of your life it is a good idea to spend two years at a community college rather than make a direct leap entrance into the university setting. 

If you are considering whether a community college or two years of education is the best action for your specific needs, I highly recommend making a list of pros and cons of each and balance your budget to see where your needs are most likely to be fully met. Remember you can always transfer to a university after you've completed the two-year college education or education at any time during the entire time you meet university admission requirements. Good luck and remember that your college education is one of the biggest indicators of your future earning potential, so take it seriously.

However, if you make yourself available at all times, you have created your own nightmare. 

Cell phone etiquette is getting to be forgotten concept. You'll see people talking on the phone loudly and disturb people nearby in restaurants and even in offices.

This is because ringing cell phone is not only annoying when you pray you will also disturb others. You do not need to show off your expensive gadget in a place of worship. 

During the meeting, please turn off your cell phone, but rude to have your phone ringing while somebody speaks. Disturbance can cause problems especially when the meetings deal with issues that are very important. However, if you're waiting for the call is very important, you can use the vibrate mode on your phone to alert you when a call comes, to leave the meeting if you need to answer the call. You can also tell the caller might be that you are in a meeting and that you will not be disturbed.When traveling and if you're on-board the aircraft, you will be asked to turn off your phone. This is because electronic devices can interfere with aircraft avionics. So, it is a requirement to change your phone for security reasons. However, for very long flights, airline companies allow cell phone usage at a certain time, if you really need to make phone calls, use this time is given if necessary. 

Mobile phones have become a necessity today, which is why most people use it and cell phone manufacturers have continuously develop different usage and functions for this gadget is very small. Globally competitive, but you must understand that being rude is not part of modernity. Follow certain degree of etiquette, this will really help you and your business.
