Computer networks and the internet are two things that are interrelated and have various benefits for modern life in today’s digital era.
Basically, computer networks are the basis of the internet. The internet is a global computer network that connects millions of computers throughout the world.
Computer networks have experienced rapid development from initially being local networks (LAN) in buildings to global networks (WAN). The development of computer networks allows you to have high speed internet access.
By using the internet network, computers and other devices that are connected to each other can communicate with each other and share data. You can do activities such as streaming videos , playing online games , and working remotely more easily.
To better understand the uses of computer networks and the internet, you need to understand the types in the discussion below.
Types of Computer Networks and the Internet
The internet network is a computer network that connects computer devices throughout the world to communicate with each other and share data. Based on their reach, computer networks and the internet can be divided into several types, namely:
1. Local Area Network (LAN)
LAN is a computer network that connects computers in a limited area, such as in one building, office or campus. Generally, LAN computer networks still use cables to connect the computers.
LAN networks offer various advantages, such as high data transfer speeds, data security, and relatively low installation and maintenance costs. However, LANs have limited coverage areas and are susceptible to electromagnetic interference.
2. Metropolitan Area Network (MAN)
This second type of computer network connects computers in a wider area than a LAN, but is still smaller than a WAN network. MAN’s range usually ranges from 10-50 kilometers.
The main function of a MAN network is to connect various LANs in a city or metropolitan area. MAN networks can also be used to provide internet access to users in a city or metropolitan area.
3. Wide Area Network (WAN)
Next, there is a type of WAN network that connects computers in a very wide area, such as within one country or continent. WANs usually use telecommunications networks, such as telephone networks or satellite networks to connect computers.
4. Personal Area Network (PAN)
PAN is a computer network that connects computer devices within personal reach, such as computers, smartphones and printers. PAN networks usually use wireless technology , such as Bluetooth and WiFi.
Examples of using PAN computer and internet networks are to connect computers with printers, connect smartphones with audio devices, or connect gaming devices with display devices.
5. Wireless Local Area Network (WLAN)
A wireless local area network (WLAN) computer network is a wireless computer network that connects two or more devices in a limited area, such as a home, office, or school.
Compared to wired computer networks, WLAN offers various advantages such as flexibility and ease of installation.
Of the five types of computer and internet networks above, the types of networks most commonly used today are LAN and WAN. LAN is used to connect computer devices within an organization or company, while WAN is used to connect separate LAN networks.
Benefits of Computer Networks and the Internet
Computer networks and the internet have many benefits for human life, both in the fields of education, business and entertainment. Here are some of the benefits:
1. Improve communication
The main benefit of computer networks and the internet is for communication between users, both directly and indirectly. With a computer network, you can exchange information and communicate in real time through various media, such as email, instant messaging, video conferences and social media.
2. Increase productivity
With computer networks and the internet, you can increase productivity. Because computer networks and the internet allow you to access information and resources quickly and easily.
As a user, you can use computer networks and the internet to do assignments, study and produce work that can be accessed online .
3. Make it easier to access information
One of the main benefits of computer networks and the internet is to facilitate access to information from various sources, both local and global. You can access various information, such as news, articles, research and entertainment.
Computer networks and the internet allow information to be shared quickly and easily. This makes the information available always up-to-date .
4. Open business opportunities
The presence of computer networks and the internet also opened the door to e-commerce and online business . Currently there are many small businesses that use computer networks and the internet to sell products online .
