History of the Internet

History of the Internet - Most citizens of the world today use the Internet, even able to say almost all people, especially in urban areas have experienced internet access. But it was not the least is still a wide variety of people in different parts of the world, even including in Indonesia who still has not been able to enjoy access to the internet, which passes penyebabanya not least, among others, because that area is exceeded by far for the network to reach the Internet, the lack of attention from the local government , and still not a little longer. Do You Know? Internet history begins with the creation of a network technology pc against th 1960. What is a computer network? Computer network that many pc that access each other together in one room using a cable that has a reciprocal interaction, for example, in an office or building. pengertian internet secara singkat

History of the development of the Internet world

Developments that when this happened really fast internet world. How not, who was only able to enjoy some particular person and function is also limited, this time entirely of people can use it not only shared with no access to news that is much broader and more functions that various kinds. Aspect was certainly ditennggarai the great discoveries that are on the Internet itself. Just can only rural population in Indonesia alone who are not internet access, because the construction of the Internet network in Indonesia is uneven.

We are an internet consumers in this sophisticated era which certainly can be very useful when digging knowledge about the history of the Internet, as a token of gratitude the internet because this time we can change the world civilization. Because we think probably not a few people who is very highly dependent on the internet in daily life, ranging from the use of social facilities of the entertainment or business, read an interesting article on the web, through chat activity closest colleagues. Please see more details of its history through the explanation of Espilen Blog below.

History of the Internet

History begins to date in August 1962 and the creation of the Internet prime time stated by a named JCR Licklider of MIT Massachutts Institute of Technology. The initial plan called "Galactic Network" by him. He expressed concerns in any manner that allows a global network of people able to connect the data and events from anywhere. To October 1962 he headed the computer research program at ARPA which is the field of defense Departmenet United States.

History of the Internet and the proliferation of the Internet Complete

Of the ARPANET project is to draft a form of network, reliability, and how much information to be transferred, that the results are entirely standard ensures that they can be the origin of the construction of new protocols that now we know along the term TCP / IP (Transmission Control Protocol / Internet Protocol).

The early history of the construction project is For military purposes. At that time the US Department of Defense (US Department of Defense) creates a system of computer networks that spread with connecting computers in areas vital to suppress the problem in case of a nuclear attack and to avoid the occurrence of a centralized news, that if the war lasts will be easily destroyed.

Against yr 1966 Larry Roberts developed the idea of ​​a computer network. Afterwards he planned jaringa who called ARPANET which was published on th, 1967. In the year 1969 the ARPANET already involves four pc that is connected.

The history of the Internet and computer premiere was started together at the University of California Los Angelos, two computers to be in the Stanford Research Institute, 3rd computer located at the University of California Barbara & koputer to emat located at the University of Utah. Against the yr 1971, the number of pc which opens to the ARPANET reached 14 pieces. For this reason yr Telnet and FTP protocols successfully constructed. To yr 1972 Larry Roberts and Bob Kahn introduces the ARPANET to the ICCC conference which was held in Washignton.

History In the year 1972 the historical development of the Internet exposes Ray Tomliinson post events that allow electronic mail sent to the network ARPNET. It was he who made the conversion design "user @ host." To th is also ARPANET NCP For menstransfer use of data. The same th ARPA are changed his name to DARPA. Adding the letter D is derived from the Defense. Against this th international connections ARPANET do germinal with the University College of London and the Royal Establishment in Norway.

History of the yr 1978 to Unix Copy Protocol is found in Bell Laboratory. This event is beneficial to implement file transfer. To the news in 1979 that the group given the name USENET operates with basic UUCP. Its creator is Tom Truscott and Jim Ellis (2nd student at Duke University) and Steven Bellovin (from Campus North Carolina).

Users of the whole world to join this discussion group to discuss networking, politics, religion and other diverse topics. Internet history, against the yr 1982 DCA or the Defense Communications Agency and DARPA print protocol which is called TCP / IP For the ARPANET. Afterwards, the US Defense Department calls the TCP / IP protocol as a fruit sntadar. Dikala that defined the internet which is a set of network who access that use TCP / IP as well as the protocol.

History of the Internet to the yr 1983 John Postel and Paul Mockapetris and Craig Partidge develop the Domain Name System (DNS) and mengusulka user@host.cdomain shaped observation system. Against yr 1984 was introduced in the Internet DNS along mention names such as domain categories. .gov, .mil, .org, .net dan.com.

The yr 1986 TCP / IP from the start ready to workstaiton & Computers. Yr is also a National Science Foundation funded NSFNET backbone which is a capacity of 56 kbps and just as were intended to regulate the internet and government research needs that are not commercial.

Advantages of Linux Operating System

Operating System (OS) Linux and Windows have their advantages and disadvantages of each ,. The ease and convenience of using the OS usually influenced habit of using it. People who are accustomed to using Windows would consider using them more comfortable, as well as Linux users will feel comfortable if frequent use.

advantages and disadvantages of ubuntu linux linux linux mint debian linux fedora linux redhat linux suse slackware linux centos

Advantages of Linux Operating System

In the case of the Linux OS has some advantages and disadvantages, keunnggulan linux diataranya as follows.

a. Requires more hardware resources tiny fraction compared to using Windows, Linux computer to run just simply use the equivalent Intel Pentium 100 processor (Pentium Classic) with 32 MB of memory.

b. Higher security level. Linux has the permissions that can be set by the administrator of Linux TSB. So the existing data on linux PC can be kept out of the hands of ignorant who want to see our data. Besides linux requires login first if you want to get into the system. Unlike the Windows 9.x / Me that allow anyone into the fungsi sistem operasi.

c. Relatively thick against viruses. Perhaps this is favored by the users of linux. Unix-based systems have been known to computer viruses. Except this time there has been a virus capable of destroying it. if there is a virus that has been programmed to damage the windows system this can not be done in linux because they both have a different kernel.

d.Tampilan desktop varied. If you are using Linux, you can make the desktop becomes more varied that hard to do in the windows. Another advantage which we can modify the menu and access to the file to rejuvenate your work. Besides, ordinary users who want to tinker with linux at best only be stunned to see the desktop of our design, because it does not know what to do with such a desktop display.

e. Cheap price. You can copy the linux installation CD borrowed from a friend. when compared with windows that cost $ 100 this is certainly the best option is linux.

f. Stable. Possess a stable Linux kernel, he can run 24 hours a day 7 days seminggun without having to be restarted. and this makes linux be superior when compared to windows.

g. Minimum Hardware. Linux does not so require large hardware capacity.

h. Shared Liblaries. Not damaging other systems if diinsatall with other versions and systems used to run as usual.

i. Multitasking, which allows access to programs or data simultaneously without any hang on the computer.

j. Linux comes with a local proxy server used by ISPs and college campuses around the world.

Weakness OS Linux

Above are some of the advantages of the Linux OS. However, as we have mentioned above that Linux also has shortcomings that you should know before you use it. And Cons Linux OS are as follows:

a. Operating system used is very different from Windows, so you have to relearn to menggunkannyaa, and need time to get to know more in linux. And this is something quite disturbing for those users who want to switch to linux.

b. Use of WYSYWYG (What You See is What You Get) There thoroughly and so needed trk own for how to use it.

c. Found loopholes Linux is a weakness in the Wifi driver used for a computer with a Linux OS, Through these loopholes attacker may be able to control a computer or even a laptop is not currently active on the network hotspot.

Domain names

Domain names - Every existing sites the internet has to address. The website address called URL stands for Uniform Resource Locator. site address usually have a relationship with the agency or organization that site owner. For example http://www.itb.ac.id owned Bandung Institute of Technology, Http://www.klikbca.ac.id owned BCA and others. Most name of the site is named in conformity with the purpose of our site or the information displayed, for example http://www.lyrics.com sites that store liriklirik song, Http://www.haznacomputer.blogspot.com which provide information about the Computer Engineering and Networks and so forth.

A website address is a combination of the protocol used (see also: definition of protocol) host name, and domain name. The domain name itself can consist of the company or the name of the site along with a code that describes the origin country code and forms of organization of the site owner.

Name domain name throughout the country

To make it easier to recognize the address of the site, naming the website address given domain name, the domain is the alphabet that were added after the name of the site. The domain name can be a state agency or organization.

Domain dot com, dot net and dot org are some of the domain names are commonly used universally throughout the world. In addition to the universal domains, there is a domain name that is specific to a state, eg dot id (Indonesia), dot jp (Japan, dot us (USA), etc. The domains are above named with the main domain. In addition to the main domain there are also the so-called sub-domains, namely an additional front of the main domain name, for example: .co.id, .co.cc, .wordpress.com.

Here is the domain name is Universal.

Understanding of computer networks

Understanding of computer networks - in the current information age, the need for information is very important, especially in a business, therefore the people working in a TEAM, working together to exchange information and various sumberdaya.Untuk supports the exchange of data and information as well as various resources then we need a computer network, on this occasion we will discuss the definition of computer networks, and will be forwarded to the benefits of computer networks and types of computer networks to network devices komputer.maka of it let's follow up to finish this post.

computer network

The role of computers in their daily lives more and more important. Various activities in various fields of business and industry is done by using komputer.Oleh because it needs the data and information data processing, for smooth and efficiency for data processing an information dar one computer to another, then the computer is a computer that is connected to each other, a collection computers connected to one another is called the computer network.

In an existing computer network called the server computer and multiple client computers. as the name suggests, a computer server serves to meelayani shipment and delivery of data from computers on the network. In other words, the server computer is used to regulate the flow of data in the network. In addition, the computer server also serves to resource providers required by the client computers.

If the computer network connected to the Internet, a computer server can also serve as a gateway, referred to as the gateway for the server computer is a gateway or track diguanakan by client computers to access the internet.

In addition, the server computer may also act sebgai web server that serves to store pages webdari page of a website, as well as mail servers or computers that provide mail service.

The function of a computer operating system

The function of a computer operating system - After we discuss the notion of the operating system then we will discuss the complete functionality of the operating system. The operating system has two main functions: managing all sources of resources contained in the computer system, see the definition of a computer system, in addition to the functions of a computer system is a set of service provider to the user so that the user easier and more convenient to use or exploit the resources of computer systems which is often referred to as system calls.

The computer system resources are all components disistem computer that can benefit, these resources consist of physical resources just as a keyboard, and mouse reader, and abstract resources such as data and programs. As we discussed in terms of a computer system that the computer system is a set of power to move, store and process data and others. the operating system responsible for managing the resources so that users of the resource users can use it correctly and efficiently, while the operating system tasks such as the following:

a. Perform memory management

b. Providing management processor that can manage the computers to be used by multiple users. see also understanding the processor and how to choose the right processor. as well as other types of processor

c. Menyadiakan management of equipment (device management)

d. Providing management information

While it is called by the computer user is anyone who wants in work completed by a computer system.

and so many of us, on the functions of the computer's operating system may be useful.
