1.Internet Technology
The internet is an abbreviation of interconnected networking, which means computer connections of various types that form a network system that covers the whole world (global computer network) through telecommunications lines such as telephone, radio links, satellites and others. The term INTERNET comes from the Latin inter, which means "between". The Internet is a virtual world of computer networks (interconnections) which are made up of billions of computers in the world. The internet is a relationship between various types of computers and networks in the world with different operating systems and applications where the relationship utilizes the advancement of communication media (telephone and satellite) that use standard protocols to communicate.
The Internet is a computer network formed by the United States Department of Defense in 1969, through an ARPA project called the ARPANET (Advanced Research Project Agency Network), where they demonstrated how with UNIX-based computer hardware and software, we can communicate over long distances. infinity over the telephone line.
2.Devices/Equipment in Internet technology
KIND OF INFORMATION TECHNOLOGY DEVICES
A.Computer
A computer is a tool in the form of hardware and software that is used to assist in processing data into information and storing it for display at a later time. Computer-generated information can be in the form of text, images, sound, video, and animation.

(wireless; wireless).
3.Things Affecting the Quality/Speed of the Internet Network
I. INTERNAL FACTORS
1.User's computer.
a. Computer specifications, the faster the processor and the larger the memory / RAM can make the data accessed faster too,
b. The presence of a virus on a computer, a virus can take up internet bandwidth or a virus can make the computer seem busy running programs so that the computer load becomes heavy,
c. Anti virus is not updated, if there is a new virus can infect the data or computer system. A clean system will affect the speed of internet access.
d. Operating system used,
2. User behavior on the internet
a. How many website addresses do you access at the same time? The more web addresses that are accessed at the same time, the more data that must be downloaded with the same bandwidth capacity conditions.
b. The type of website accessed also affects the speed, a website that contains videos / images takes longer to appear than a website that only contains text
c. The use of applications (software) to speed up file downloads can cause activities such as browsing to be slow.
d. the number of applications opened, for example browsing while opening multimedia applications such as music, etc.
3. Location, Strong signal only gives you a connection that is rarely intermittent
II. EXTERNAL FACTOR
1. The amount of bandwidth from the ISP
2. Media liaison between the user and the ISP
· the capacity of the media must be greater than the capacity of the source provided by the ISP. The type of media used also affects the quality of the internet that is accessed, especially for the level of stability.
· Between devices must also be compatible, for example between switches or cables, one supports big data - the other supports small data, so the data access obtained will also follow the small one.
3. Condition of the destination website
· Websites that are crowded by visitors can cause restrictions on the maximum speed that can be accessed by users, this aims to reduce the server hardware workload from the server and several other non-technical reasons. Not all websites allow their users to access with maximum speed.
· the location where the website we want to access stores its files or the server that serves it. For example, international websites such as Yahoo America, of course the server is in America, there is a difference in access time between local websites and international websites.
4. Number of internet users in one local area network or LAN.
If there are too many users, it becomes crowded because they are fighting with each other to access certain files or sites.
Of these several factors, it has been identified that in the FK UII environment, the most factors that cause slow or slow internet access are users who download files that are too large just for entertainment such as comics, videos and games that are less educational. As a result, other users are hampered in accessing it, especially if the person concerned is in control of IT so that they can lock access for their own interests without any obstacles regardless of the bandwidth. Hopefully, at FK UII, everyone can be more trustworthy and wise in using internet facilities for academic purposes. Regards/SAA
4.Positive and Negative Impacts of Internet Technology
1. Facilitate Communication
One of the positive effects of the internet is the ease of communication.
Currently, there are quite a number of applications that use the internet as a medium for sending messages.
By using the internet, messages or telephone connections can be made easier and cheaper.
Not only that, the range of communication also tends to be wider without any boundaries.
The internet makes it possible for a person to send messages or make calls to other people in different countries without any major problems.

6.Internet as a Communication Media
The internet is a program based on a network or connection from a computer that is linked to each other to spread data using the TCP / IP protocol. One of these data is information or messages.
In this increasingly developing era, the internet is a medium used as a means of communication which has gradually gotten rid of communication media such as telephone or sms (short message send). This is because it has been proven that in everyday life today, humans are attached to a network.
Because basically, the internet has become a basic human need. This happens not only for online gamers, even businessmen, politicians, and students also experience the same thing, which cannot be far from the internet. As if the internet is part of their lives. Without internet, humans will die. So, actually the internet has a positive or negative impact.
In fact, the internet has also begun to be used in several other communication science studies. Such as, Mass Communication, Political Communication, Organizational Communication, Persuasive Communication and even Visual Communication. Internet in the current era of globalization is needed to achieve effective communication.
7.Internet Connection With Communication
In the study of communication, the internet has the meaning that it is a facility for interaction with a network that can be connected globally.
So that not a few people have used this communication facility as a means of conveying their messages, especially on social media. In fact, getting here, the development of the internet is getting more sophisticated. For example, people can earn money just by sitting looking at their computer screen. Or people just sit when he wants something or shopping. Without the need to walk, humans can do their activities.
It can be said that the increasing age, the higher civilization through the internet as a means of communication. Even the internet itself continues to innovate and experience very rapid development, when compared to other advances. Because the internet itself has provided several advantages that are getting better, including:
Wider sources of information or references.
Infinite reach (far closer).
Effectiveness and time efficiency in communicating.
Cheap facilities as a quality use.
Unlimited “Google All-Knowing” transparency.
As a sophisticated and growing means of information, the internet is also able to convey and assist as a medium in communicating with anyone, even in certain organizations. So the question arises, how big is the role of the internet in our lives?
Internet as Winner
It can be said that the internet is the winner of all civilizations in humans. It has been proven a phenomenon in the United States where it is known that sales of computers and internet data are higher than television or regular credit. Even computers are also able to take on the role of computers as a means of information. So the world will shift to the digital age. Where everyone and life will be digital. Or it can be said as the 'Cyber Age'. (Also read: Gender and Communication)
This internet network can be said, that this information facility has begun to become endemic and ingrained in the socializing community. With the nature of the internet that is easily accessible, it makes people more attached to the internet and even addicted to the internet. However, they argue that this internet has many positive impacts because they can get to know new people by anyone without age restrictions, and anywhere without limitations of location distance.
And keep in mind also that this means of information is actually able to make people communicate and think more broadly. They will try to move forward because their demands follow this digital civilization. Because communication is something very important as described in the previous article.
Thus, the internet as the best means of information, makes this internet a tool that is needed by humans in their lives. In business, education, to politics, we need a means of this information, namely the internet. Until humans feel they have to be able to connect to the internet in various ways that they have.
8.Impact of the Internet in Communication
no wonder if we look to the right and left, people begin to bow and focus on their respective cellphones. This is one of the negative impacts of the internet itself. Their social sense will decrease. any culture of reprimand will be increasingly extinct in society. From children to adults, everything is inherent in them with the internet. Thus, humans will consume more time on the internet (virtual world) compared to the world of society (the real world). Experiences that are considered historical also become state of affairs that are easily known by others who do not know the individual.
However, the positive impact of the internet in this communication itself is that by spreading a network, humans also find it easier to communicate with anyone and anywhere. Thus, time will feel more efficient and effective when humans want to carry out communication activities. Because the function of the internet itself does not limit all ages and location distances. So, humans can be able to communicate with anyone and anytime to wherever we are.
Don't be surprised if now many children are also starting to understand the internet, so they often go to internet cafes to play online games. In elementary school at this time, they have been given lessons about the world of the internet.
However, it all depends on the attitude of each individual in responding to this phenomenon. If we are able to use these facilities properly and correctly, then we will not get lost and get caught up in the modernization and even digitization of this civilization. We will not be consumed by this digital civilization. In addition, we will feel profit and win against civilizations that may be able to eat us and make humans experience setbacks because of this digital era.
With the virtual world that is increasing widespread, we must be good at using it properly and correctly. Some even have an opinion and ask, "If many people pray on social media, then I will look for God's account name?"
Let us be good at doing and using this facility as a medium of good and correct information and can be accounted for. Especially now that Indonesia's Law on IT is starting to appear. This will make Indonesians not careless in expressing their opinions on social media. Because, instead of the tongue sharper than a knife, it is now replaced by the term social media status is sharper than the tongue.
So we need a wise attitude in using social media and this information tool. This is what will make us as intelligent humans in digital civilization.
