Understanding Computer Networks
Definition and Definition of the Most Complete Network - The network (network) is an operating system consisting of a number of computers and other network devices that work together to achieve the same goal or a network that consists of points (nodes) connected to one interact with each other, with or without wires. Each of these nodes is useful as a workstations. One of the nodes is as a service media or server, it is the one that regulates certain functions of other nodes. Basically, computer network technology itself is a combination between computer technology and communication technology.
Definition and Understanding of Network
The purpose of computer networks:
Networks allow resource management to be more efficient. In addition, licenses from network software can be cheaper than separate stand-alone licenses for the same number of users, and share CPU, Memory and Hardisk usage.
The network also helps maintain information that is reliable and up-to-date. A well-managed centralized data storage system will allow many users to access data from a variety of different locations, and limit access to data while being processed.
The network also helps speed up the process of sharing data (data sharing). Data transfer on a network can always be faster than other means of sharing data that are not networked.
Networks also allow working groups to communicate more efficiently. Electronic mail and delivery are the substance of most network systems, in addition to scheduling systems, project monitoring, online conferencing and groupware, all of which help teams work more productively and quickly.
Networks also help businesses in serving their clients more effectively.
Network Benefits
The main benefit that can immediately be felt from network sharing is that the Internet is worldwide, because in essence the Internet is a series of computers connected to one another. It evolves and develops over time, so it can form a complex network as we feel now.
Another advantage seen from the side of the internal network is:
Resource Sharing is that it can use the available resources together.
High reliability with our computer network will get a high reliability by having an alternative source of inventory.
Hardware sharing is for sharing hardware on time together.
Security and data management is a computer in a business environment, with the existence of such a network will allow an administrator to organize all the most important office data.
Stability and improvement in computing performance is, under certain conditions, a network can be used to improve the overall performance of business applications,
Network Losses
Here are some of the disadvantages of implementing a network:
High costs then higher.
network development includes various aspects, namely:
hardware purchase,
software,
costs for network planning consulting, then
costs for network building services themselves.
This high infestation is certainly for large companies with high network needs. Whereas for home users this fee is relatively small and can be reduced.
Hardware Management and System Administration: in a company organization that already has a system, this administration will be felt to be a small thing, at least when compared to the large work costs and costs incurred at the implementation stage. However, this is the most important step because errors at this point can result in a review that will even experience network re-construction.
Sharing unwanted files: With the good comes the bad, this is always a common thing (ambiguous), the ease of sharing files into a network intended for use by certain people, often resulting in leakage of shared folders and can be read also by other people who have no right. This will always happen if it is not set by the network administrator.
Virus applications and hacking methods are things that are always a scary problem for everyone that can cause network down and work stopping.
