NETWORK ARCHITECTURE

WHAT IS NETWORK ARCHITECTURE?

The configurations of computer, devices, and media on a network.Network architecture is the logical and structural layout of the network, consisting of transmission equipment, software and communication protocols, and infrastructure (i.e. wired or wireless) transmission of data and connectivity between components. There are 4 different network topologies: star network, a bus or line network, a loop or ring network, and a mesh network.The different topologies can be arranged in different ways, described as LAN (Local Area Network), MAN (Metropolitan Area Network), and WAN (Wide Area Network), where the network extends over a local area (<1 km), metropolitan (<100 km), and long distance area, respectively.

CATEGORIES OF A NETWORK ARCHITECTURE 

Client/server architecture is a computing model in which the server hosts, delivers and manages most of the resources and services to be consumed by the client. This type of architecture has one or more client computers connected to a central server over a network or Internet connection. This system shares computing resources.Client/server architecture may also be referred to as a networking computing model because all the requests and services are delivered over a network.

Client/server architecture is a producer-consumer computing architecture where the server acts as the producer and the client as a consumer. The server houses and provides high-end, computing-intensive services to the client on demand. These services can include applications access, storage, file sharing, printer access and/or direct access to the server’s raw computing power.

  Client/server architecture works when the client computer sends a resource or process request to the server over the network connection, which is then processed and delivered to the client. A server computer can manage several clients simultaneously, whereas one client can be connected to several servers at a time, each providing a different set of services. In its simplest form, the Internet is also based on client/server architecture where the Web server serves many simultaneous users with Web page and or website data.




Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes.


Peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts.] Peers are both suppliers and consumers of resources, in contrast to the traditional client-server model in which the consumption and supply of resources is divided. Emerging collaborative P2P systems are going beyond the era of peers doing similar things while sharing resources, and are looking for diverse peers that can bring in unique resources and capabilities to a virtual community thereby empowering it to engage in greater tasks beyond those that can be accomplished by individual peers, yet that are beneficial to all the peers.


While P2P systems had previously been used in many application domains, the architecture was popularized by the file sharing system Napster, originally released in 1999. The concept has inspired new structures and philosophies in many areas of human interaction. In such social contexts, peer-to-peer as a meme refers to the egalitarian social networking that has emerged throughout society, enabled by Internet technologies in general.

ALL ABOUT ME!

Hi guys! Since this is my first writing this blog. So, let me intro little bit about my family and also my life.

Let’s start with my queen which is my lovely mom. I have a gorgeous mom ever! I’m pretty sure that she is the prettiest. She is a kind person that I want to be. Full of confidence, full of patient. And the most importantly is she know what is the best for me. She also have a very high maternal instinct. Seriously, I don’t know how to describe her, but she just perfect for me.

My hero? hmm.. Of course my dad. I cannot move on with his jokes. Very spontaneous. He’s know everthing about current issues that sometimes I don’t know. Like seriously. You know everything dad. I’m so proud of you. I wish that we can share our brain together. So that I can think better. How lucky I am to have a perfect parents like both of you.

Next, I actually have two sisters which is very beautiful and cute. They always made my day. My second sister is one of the k-pop fan girl. K-pop all the time. Yes she is! With her phone and earphone listen to the k-pop songs and watch Korean drama. Guess what guys? Sometimes her dress up just look like Korean people. With her skinny jeans and I don’t know how to describe her dress up. I’m so falling in love with my younger sister. I called her “littlesaraakhan”. She’s so cute and naughty at the same time.

So, guys I’m done intro little bit about my family. So, it’s time to intro about myself. My name is Nurul Atiqah Binti Syafizan. I’m officially 18 years old. I’m studying at Pahang Matriculation College. Basically, I learned four subject here which is Physics, Chemistry, Mathematics and also Computer Science. I’m so falling in love with Physics subject and I also want to be Physics lecturer (InsyaAllah). But, the more I study Physics, the more I don’t know Physics. Hehe. I realized that Physics is a hard subject. When you study 

Physics keep it in your mind to ask ‘why’ so that you can solve the question better. There is a few things that people don’t know about me. I loved rainbow since I was child. I also like to watch National Geographic and horror movie. I’m very scared with spider especially Brazilian Wandering Spider. I’m so afraid when I think about that spider. Sometimes I think that snake is better than spider. Because spider is too small to see. So, ya thats all. Okay bye!

DIFFERENT BETWEEN CLIENT-SERVER AND PEER-TO-PEER

Client-server	Peer-to-peer
For medium and large network	For small network fewer than 10 computer
Needs training	Does not needs training
More difficult to set up	Easy to set up
More expensive to install	Less expensive to install

What is network?

A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data. An excellent example of a network is the internet, which connects millions of people all over the world. Below is an example image of a home network with multiple computers and other network devices all connected to each other and the Internet

A computer network, or data network, is a digital telecommunications network which allows nodes to share resources. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media.

Network computer devices that originate, route and terminate the data are called network nodes.Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. In most cases, application-specific communications protocols are layered (i.e. carried as payload) over other more general communications protocols. This formidable collection of information technology requires skilled network management to keep it all running reliably.

Computer networks support an enormous number of applications and services such as access to the World Wide Web, digital video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications as well as many others. Computer networks differ in the transmission medium used to carry their signals, communications protocols to organize network traffic, the network's size, topology and organizational intent. The best-known computer network is the Internet.
