Pengertian Komputer

Di kutip dari Wikipedia, Komputer adalah alat yang dipakai untuk mengolah data menurut prosedur yang telah dirumuskan. Kata computer pada awalnya dipergunakan untuk menggambarkan orang yang perkerjaannya melakukan perhitungan aritmetika, dengan atau tanpa alat bantu, tetapi arti kata ini kemudian dipindahkan kepada mesin itu sendiri. Asal mulanya, pengolahan informasi hampir eksklusif berhubungan dengan masalah aritmetika, tetapi komputer modern dipakai untuk banyak tugas yang tidak berhubungan dengan matematika.

Dalam arti seperti itu terdapat alat seperti slide rule, jenis kalkulator mekanik mulai dari abakus dan seterusnya, sampai semua komputer elektronik yang kontemporer. Istilah lebih baik yang cocok untuk arti luas seperti "komputer" adalah "yang mengolah informasi" atau "sistem pengolah informasi." Selama bertahun-tahun sudah ada beberapa arti yang berbeda dalam kata "komputer", dan beberapa kata yang berbeda tersebut sekarang disebut sebagai komputer.

Kata computer secara umum pernah dipergunakan untuk mendefiniskan orang yang melakukan perhitungan aritmetika, dengan atau tanpa mesin pembantu. Menurut Barnhart Concise Dictionary of Etymology, kata tersebut digunakan dalam bahasa Inggris pada tahun 1646 sebagai kata untuk "orang yang menghitung" kemudian menjelang 1897 juga digunakan sebagai "alat hitung mekanis". Selama Perang Dunia II kata tersebut menunjuk kepada para pekerja wanita Amerika Serikat dan Inggris yang pekerjaannya menghitung jalan artileri perang dengan mesin hitung.

Charles Babbage mendesain salah satu mesin hitung pertama yang disebut mesin analitikal. Selain itu, berbagai alat mesin sederhana seperti slide rule juga sudah dapat dikatakan sebagai komputer

Rapid Prototyping, 3D printing , FDM

Rapid Prototyping is the process to build the physical parts directly from the data the Computer Aided Design (CAD). This process is based on additive manufacturing technique, is a 3d object is created by bonding thin slices of material layer by layer. 3D printing is a generic term used primarily for additive manufacturing, where the object is constructed layer by layer. There are a number of technologies 3DP, borrowed from the large RP systems, the main difference is the choice of material, build speed and accuracy of parts. NC stands for Computer Numerical Control, refers to a computer "controller", that drives the machine. CNC machining is one of our most used services, suitable for functional, smooth and precise machined part directly from the engineering plastics or metals. Please check our CNC reserved for extensive information. FDM is also known as the Fused deposition modeling is layered additive manufacturing system. FDM offers functional and durable prototypes in...

Rapid prototyping

Rapid prototyping is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data.[1][2] Construction of the part or assembly is usually done using 3D printing or "additive layer manufacturing" technology.[3] The first methods for rapid prototyping became available in the late 1980s and were used to produce models and prototype parts. Today, they are used for a wide range of applications[4] and are used to manufacture production-quality parts in relatively small numbers if desired without the typical unfavorable short-run economics. This economy has encouraged online service bureaus. Historical surveys of RP technology[2] start with discussions of simulacra production techniques used by 19th-century sculptors. Some modern sculptors use the progeny technology to produce exhibitions.[5] The ability to reproduce designs from a dataset has given rise to issues of rights, as it is now possib...
