Network nowadays in essential in many aspects of business, social and educational. The Network is so called connection, between men, between machine nor computer. By creating a network, someone or something will be far more productive rather than single, standalone object.
Today, we talked about computer network. Same as before, a connection between 2 or more object to achieve multiple objective. This "object" refers to computers. Computer alone can do many things but it is depends on how the user uses it. But by network, some aspect in computer a far more fascinating that those simple painting.
Every thing needs a plan. there is no excluding in computer network. When there is plan, there is architecture.
Architecture
To create an architecture of computer network, someone needs to calculate several things before move the environment to the desired architecture.
First of all, Scalability issue. From time to time the company will expand and we need to add new nodes. The problem is reside in the hardware. How many port/patch panel/modular jack needed to complete this task?
"scalability is the ability of a system, network, or process, to handle a growing amount of work in a capable manner or its ability to be enlarged to accommodate that growth. - wikipedia"
Lets say, the company have 5 computer right now. But the business is expanding. They need to use accountant department and centralize server. If you only buy hardware that only support 5 computers. The company surely have a hard time in budgeting the company revenue.
Why It Counts?
Based on the number of nodes and analytically increment over years, the major problem about connection between nodes is Reliability of the network itself. Reliability here means the connection are stable and smooth.
Reliability is a protocol to ensure the network stable and ready to use to send data over the network. For example, data request when certain packet are drop or damage due to the transmission over the line. Other than that, it also describe as reduce down time network which is mean that the network never disconnect its own client to satisfy other priority.
"Realibility of a network often been tested by data transmitting. the way their doing the test is to stress the network with high volume of data transmitting until it fail."
Work Load
When things became real demanding and real-time, the workload will become very important. The workload in network is how many concurrent connection made by end user to server. What the server serve to satisfying user needs? how big the data that being transmitted throughout the line?
At the end, workload depends on how users utilize that network. if the network is use for p2p downloading, the traffic will be sky high because the line receive larger data volume simultaneously. If in the network have high users traffic, i mean u need to change several things to be automaton, for example a server. a server can serve up to 300 users in one SME company.
Thats all for today. see ya. if any question, pls comment below.
