Get to know the Internet Network
This computer network is actually building communication between computers to be able to exchange with each other.
In addition, the purpose of this computer network is to be able to achieve goals, and each computer can provide and request services.
Definition of Computer Networks
The definition of a computer network is a system consisting of several computers designed to be able to share information, resources, communicate, and be able to access information together.
History of Computer Networks
The history of computer networks itself originally emerged because of the idea of using one computer together.
The project was run by a group of researchers headed by Howard Aiken of Harvard University’s Bell Laboratory.
In 1950 the first super computer was created, that’s when the TSS system or time sharing system was also found.
At this moment is one of the important history where the network was first applied.
In 1982 the first TCP protocol was created then DNS was also found which of course was born computer network. Then in 1990 the WWW or World Wide Web program was created which made computer networks grow.
Types of Computer Networks Based on Scale
Of course, the advantages of computer networks depend on what type of network is used based on the scale.
Local Area Networks (LANs)
LAN networks have the function of connecting network devices in conditions of small coverage. For example, this LAN is for school, office, home and company networks.
Metropolitan Area Network (MAN)
MAN is a network that connects one computer to another within the scope of the City with the same network. This type of network is much larger than a LAN.
Wide Area Network (WAN)
WAN is a collection of LANs that are geographically dispersed. WAN is almost similar to MAN but with a longer distance that is commonly used in ATM networks.
Person Area Network (Pan)
This network is the smallest network among other networks. Usually used only for internet purposes or to share printer devices.
Virtual Private Networks (VPNs)
VPN or virtual private network is a type of network to make internet connection more secure. This VPN is provided by VPN providers with varying prices.
This VPN is also a solution for users who want to access websites that are blocked by ISPs.
The Internet is the most extensive and largest network. The internet covers almost the entire world with broad access to various sources of information on various computer devices such as PCs, smartphones, laptops, TVs, tablets, and so on.
This internet can be accessed anywhere and anytime by users who want to find information easily and quickly.
Types of Computer Networks Based on Their Functions
After that there are also types of networks based on their functions which of course have different network advantages. The following are types of network types based on their function:
Peer To Peer
This type of computer network is where a computer network can be both a server and a client. Each computer can receive and provide access from other computers and computers.
Client server is a network where one computer functions as a server. Such as server computers in companies that provide web access, e-mail, and many intranet applications that are accessed by clients via a browser.
Network Types Based on Transmission Media
There are also networks based on the transmission media, among others.
A computer network that uses cables as a transmission medium. In a computer network, of course, the transmission media has a very important role in transmitting information or data to be transported through the transmission media. Cable types include coaxial cable, twisted pair cable and fiber optic cable.
Wireless is a transmission medium that uses data transmission media without using cables. This type of wireless can use radio waves, infrared, Bluetooth, and WiFi networks.
Computer Network Topology
This commuter network topology is a network. There are two kinds of topologies, namely logical topology and physical topology.
In general, there are five physical topology models namely bus, ring, star, extended star, and mesh. The following are some types of topologies in general:
This bus topology is a type of topology that uses a single backbone cable to connect between nodes in a network.
Ring Topology (Ring)
The ring topology connects nodes with each other, the last connected to the first node so that the nodes are connected in a network similar to a ring.
Star Topology (Star)
This star topology connects all nodes to one central mode. These nodes are usually hubs or switches.
Tree Topology (Tree)
Tre topology is a combination of bus topology and star topology. This tree topology is similar in shape to the root of a tree in that you can say that only hub devices are connected directly to the tree bus. And each hub functions as the root of this tree topology.
This mesh topology is indeed most often used when a condition where there is no absolute disconnection of communication links between nodes in a computer network. These devices are connected directly as long as they are in the same network.
And the last topology is a logical topology, this logical topology consists of two types, including:
In this topology, all hosts can send data to all devices on the transmission medium with the principle of first come first serve.
This token passing topology is able to control network access by passing electronic tokens on each host in turn. When this host receives the token, the host can send data. If not, then the data sent by the token is passed to the next host and this process will continue to be repeated.
Some Computer Network Devices
There are several kinds of computer network devices so that they can help and optimize the work of the network system. Here are some devices that you can find on the market, including:
Server is a computer that is used as a client server and a place to store various sources of information, as well as manage computer networks.
NIC(Network Interface Card)
NIC or its familiar name is a LAN card expansion board that is used so that computers can connect to the network. Ethernet itself is divided into four types, namely Ethernet 10 Mbit/second, Fast Ethernet 100 Mbit/second, Gigabit Ethernet 1000 Mbit/second, and Tengig 10000 Mbit/second.
Cable is a medium to connect one device to another. Several types of cables for the manufacture of network channels. Cable types include coaxial, fiber optic, and twisted pair.
Hubs and Switches
Switch is a computer network device that functions to connect several computers. The shape of the hub and switch is similar but has a different logic. There are two types of switches, namely unmanaged switches and managed switches.
Router is a type of device that functions to connect LAN networks to WAN networks, and manage networks.
Bridge is a device that is used to forward resources between network segments based on information to a data link.
Bridge also has a function in dividing a large network into several small networks.
Modem is a type of device used to connect a computer with an internet service provider or ISP.
A repeater is a device that functions as a booster and regenerates incoming networks and signals. This repeater can extend the signal from the router and amplify the signal. The downside of the repeater itself is that it cannot filter traffic within the network.
Wireless card is a must-use device for those of you who want to connect your computer to a wireless network. Generally, the latest types of computers already use devices that support wireless cards. But there are also wireless card devices that you can add yourself to a computer that doesn’t have a wireless card in it yet.
Some Advantages of Computer Networks
So, earlier we have discussed several definitions of computer networks, their purpose, to the types of computer networks from various categories. In discussing the advantages of the computer network itself, it may be seen from various sides, including network sharing that is worldwide, because the purpose of the internet itself is a collection of computers with a very large number and are connected to each other, which evolve and develop over time so that can form a complex network as we feel now.
Other network advantages that can be seen from the internet network side are:
Advantages Network can share resources (data, programs, computer peripherals)
The main advantage of the network is to share resources and be able to use resources simultaneously. For example, users who are far away or in different countries from data have no difficulty using this data, as if they could access it from their own personal computer. It is also often interpreted that computer networks overcome distance problems.
Advantages Effective communication media network and multimedia
The next advantage of the network is to create effective communication and multimedia where users can easily access media content such as images, video, sound and text easily using the internet network. Not only that, users can also use the network as a means of communication that is efficient and also fast.
Advantage Network enables more efficient resource management.
With the network provides advantages in more efficient resource management. By using the network, the resources on the server can be easily accessed by client computers and used for various needs.
Advantages Network allows for more unified delivery.
Broadcast is one of the most important network advantages. Where there is one computer that wants to serve many computers at once without the need to distribute resources one by one.
Advantages Networks allow work groups to communicate more efficiently.
This network advantage can enable workgroups to communicate more efficiently. Where currently there are still many companies implementing WFH or work from home where inevitably everything is done online using the internet network.
Therefore, workers who are at home can still access information resources on company servers using the internet easily and quickly. Not only that, workers can also conduct online meetings by utilizing video conferencing facilities where everyone can still discuss with each other via a simultaneous and integrated video call connection.
The advantage of the network is that it can maintain data security (access rights).
The network advantage can keep data security more secure in terms of access rights. Yes, this network can provide more secure data security if you want to access data from servers within the company’s internal network more safely.
Advantages The network saves development and maintenance costs.
Network advantages save on development and maintenance costs. In fact, computer networks continue to grow and require regular maintenance so that they can be used continuously. However the cost of using a computer is usually quite high without using a network. Because with a computer network we can save development costs in communicating, sending files, and so on.
Advantages Network helps to keep information reliable and up to date.
With the latter network advantage is in helping to maintain information so that it remains reliable and up to date. The point is that the network can help maintain data so that it is continuously updated and users will still be able to access information more freely without worrying about running out of the latest information.
From some of our discussions above, the point is that we discuss what are the advantages of networking in our lives.
As previously said, the network itself was created to help connect several computers so that they can exchange information with each other.
In addition, this computer network can help us in terms of long-distance communication. Imagine if we didn’t have a network such as a telephone, video call, or e-mail, we would still use mail to find out news from someone who is very far away.
This will certainly make it easier for us to communicate remotely without the need to meet face to face with each other.
Another advantage of the network is that it saves on expenses for sending documentation and telecommunication. In ancient times, before the existence of the internet, we communicated using the telephone, of course, it would be very expensive, especially if the one we contact was in a place that was very far away, even abroad.
Just imagine if we call one minute can spend a lot of money. Now by using the internet network, we can make telephone calls using the VOIP system or certain applications that help us in telecommunications such as WhatsApp, Facebook, Twitter, Instagram, and so on.
From a company perspective, using a network is a huge advantage, especially if the company often uses computers for work. So that by using the network, the data in the company can be accessed by workers from anywhere and at any time in terms of more secure and efficient security.
