They differ in how data is sent over a communication medium, the frequency range they use, and their applications.Broadband systems use modulation techniques to reduce the effect of noise in the enviro
When Bluetooth headphones connect to a smartphone, this is done via a personal area network (PAN). PAN networks are used to connect small devices within a range that is close to the user, making them useful in everyday life. Find out when a PAN is used and what advantages this…
In addition, many offices only have one printer or a few printers that are shared by everyone. Without a network, the IT department would have to connect every single computer to the printer, which is difficult to implement from a technical standpoint.
There are several types of computer networks. Which network an organization uses depends on factors such as the number of devices, types of operating systems, transmission medium used, network topology, the distance between each device and their geographic scale.
Storage capacity. Most organizations scale over time and have an abundance of data that needs storage.

A metropolitan area network (MAN) connects individual computer resources in an area of up to 100 kilometers. Smaller 男同网 than a wide area network, it’s an efficient option for secure and stable data transfer within areas that are too large for a local area network. We’ll explain what…
Ensuring the security of a network is crucial to protect data and resources from unauthorized access and attacks. Key aspects of network security include:
Devices attached to a computer network use IP addresses that are resolved into hostnames through a domain name system server to communicate with each other over the Net and on other computer networks.
This internal IP address is used only for communication between the participants in the local network. For communication on the Internet, external IP addresses are used that are automatically assigned by the Net provider.
Star Topology: In star topology all devices are connected to a central node called hub or switch. The hub controls the flow of data between devices. If one device fails the rest of the network is unaffected. But, if the central hub fails the whole network stops working.
, or Equipment of a Data Terminal like connecting two computers or more. Link in Computer Networks can be defined as wires or cables or free space of wireless networks.
Understanding the basics of computer networking is essential in today’s interconnected world. Networks enable the seamless exchange of information, support countless applications, and underpin the functionality of the Net.
There are usually multiple network protocols that each perform a specific subtask and are hierarchically organized into layers.
