I regret having to say this. I didn’t publish the post throughout the past few days. I’m occupied with work for my internship. I will make sure that won’t happen again.
Functions of Computer Networks
In the late 1950s, the first computer networks were developed for use in defense and military applications. They initially had limited commercial and scientific applications and were used to transport data via telephone lines. The development of internet technologies has made computer networks essential for businesses.
More than just connection is provided by contemporary network systems. They are essential to modern company performance and the digital transformation of industries. Network underpinnings now include more programmable, automated, and secure features.
Operate virtually
Several “overlay” networks can be created by conceptually partitioning the underlying physical network architecture. The nodes in an overlay computer network are virtually connected, and data may be sent between them via a number of different physical channels. For instance, the internet is used to overlay several business networks.
Integrate on a large scale
Computer networks that are physically separated are connected by modern networking services. By automation and monitoring, these services may enhance network operations and build a single, expansive, high-performance network. Depending on demand, network services can be scaled up or down.
Respond quickly to changing conditions
Many computer networks are defined by software. A digital interface can be used to centrally route and manage traffic. These computer networks allow for the administration of virtual traffic.
Provide data security
Access control and encryption are built-in security features in all networking technologies. To increase network security, third-party programmes like firewalls, anti malware, and antivirus software can be incorporated.
What are the types of computer network architecture?
Computer network design falls under two broad categories
- Client-server architecture
Nodes in this kind of computer network might be clients or servers. Client nodes receive resources from server nodes, such as memory, computing power, or data. Client node activity may also be controlled by server nodes. Although clients can interact with one another, they can not exchange resources.
For instance, some computers in business networks save information and setup preferences. The network’s servers are represented by these devices. Clients can request access to this data from the server computer.
2. Peer-to-peer architecture
The linked computers in a peer-to-peer (P2P) architecture share the same rights and privileges. No centralized server is present for coordination. Each computer network device has the option of serving or acting as a client.
A portion of each peer’s resources, such as memory and processing power, may be shared across the whole computer network. For instance, several businesses host memory-intensive programmes, including 3-D graphic rendering, across numerous digital devices using P2P architecture.
Different Types of Networks
Base on Transmission Medium
- Wired Connection (Fiber Optic cable,Co-oxial cable,Twisted pair cable )
- Wireless Connection (IEEE 802.11)
Base on Range
- PAN (Personal Area Network )
- MAN (Metropolitan Area Network )
- LAN (Local Area Network )
- GAN (Global Area Network )
In my following post on the medium, I will clarify them. see you guys shortly.Thank you For Reading my Post .Stay Update With me.
