Getting to Know the Types of Computer Network
Computer network is a system which consists of a group of computers connected one another to share information and power. The types of computer network are divided into three parts. They are:
1. Based on the location width
a. LAN (Local Area Network)
This is a local computer network which has very limited area scope. It uses UTP cable or the wireless one. It is usually used in schools, offices, or houses. The advantages of LAN are:
– Parallel use of equipments, such as printer and CPU.
– Easy to share data
– Easier maintenance if the client-server for data management is arranged centered.
b. MAN (Metropolitan Area Network)
This is several LANs which are connected altogether. Media used are wireless and optic fiber. The range scope is around 50 km, depends on what media is used.
c. WAN (Wide Area Network)
This is a group of LAN and MAN which are integrated each other. WAN leads to high-speed data transfer so that it is possible to have faster and more exact communication and data sharing. The association of WAN leads to internet working, which we usually call ‘internet’.
2. Based on the configuration
a. Peer-to-Peer (P2P)
In P2P, each computer has the same position and it does not need a centered system. The advantages are the configuration is easy to make, server computer is not needed, cheap installation budget, and does not need technician with such specific ability. On the contrary, it has lower data security, limited computers, and longer maintenance process.
b. Client/server
It requires a computer which becomes the server to control the network. It has higher data security, unlimited computer quantity, and easier maintenance process. Meanwhile, it also has difficult configuration, expensive installation budget, and needs technician with a specialty.
3. Based on the used media
a. Cable
This is used if the are scope is not too broad. The types of cable used are UTP, optic fiber, and Coaxial.
b. Nircable or wireless
It really assists if it is used in the limited for cables. The media are wireless LAN, infrared, cellphones, satellite, and bluetooth for instance.

Engineering Services For Mass Production
Business people often rely on the expertise of engineers and technicians that could turn ideas into reality. Product concepts can’t become a reality without the technical skills of experts in manufacturing. Therefore, engineering services must be hired by any business that wants to mass produce items for the consumer market. First of all, digital blueprints for a product idea must be carefully reviewed and evaluated. Engineers can make some modifications to the original plans for a product design. For example, some features of an item may not be easily manufactured. At the end of the day, business people and scientists must compromise on the most realistic product concept.
Before an item can be mass produced, protocol models must be created. The purpose of manufacturing samples it to get an idea of how items actually look, feel and operate. A protocol may be made from actual materials that are specified in the product design plans. The sample models must be extensively tested for quality control. For example, safety tests are applied to make sure that products do not pose any hazards as specified by government regulations.
Engineering services can also optimize a manufacturing process for a particular product line. The automated assembly lines and robotic operations may have to be adjusted accordingly. Business can learn more about the various types of manufacturing options that are available for mass producing particular items for the consumer market. Decisions on the types of materials must be made in order to stay within a budget.
