Different about Microcontroller and Single Board Computer

Learning embedded systems is a good way to learn more about computer architecture. In the PC / Tablet / Smartphone, there are so many "layers" which complicates our understanding of the hardware, but in embedded systems, we can directly interact with the hardware, even without using the operating system at all.

There are currently two popular paths for learning embedded systems: use a single board computer (eg: Raspberry Pi, BeagleBoard, BeagleBone Black, Cubie Board, RadXa, etc.), or using a single-board microcontroller (eg: different versions of Arduino, Parallax Propeller, LaunchPad MSP430, etc). Abbreviations SBC single board computer for commonly used, but single-board microcontroller usually not abbreviated, but that this quick article, I will briefly as SBM.

Single Board Computer

As the name implies, single board microcomputer is a computer within a board.This means that anything that can be done by a computer can be done by SBC.SBC currently has a large memory (128 MB-2 GB, even some have more), have an external storage (SD Card / USB disk), and has a processor speed in the hundreds of megahertz to gigahertz, some even quad core.

An SBC typically have an operating system (usually Linux, FreeBSD, or another open source OS), and we can run the program in any language in situ (eg: C, Python, Lisp or even the prologue). Although usually have the operating system, we could have been programmed without an operating system.

Single Board Microcontroller

A microcontroller is a computer as well, in an existing microcontroller chip processor cores, memory, and input / output system. Usually RAM in microcontroller is very small compared with the SBC (hundreds of kilobytes, up to several megabytes), storage is also limited (hundreds of kilobytes, except when related to the external storage, such as SD Card), speed is also limited (usually less than 100 Mhz).

A microcontroller typically programmed directly without operating system.Although there are several OS for microcontrollers, his ability is very different from the OS to the computer. The language used to program the microcontroller is actually varied, but usually people choose to use assembly or C / C ++. Single-board microcontroller which is most famous today (Arduino) using the Wiring language is actually a subset of C ++.

A Single Board Computer(SBC) is a printed circuit board (PCB) with a microcontroller and all components needed to make it function as a small computer. A microcontroller is just the processor of the SBC.

Secret of Single Board Computer

SINGLE BOARD COMPUTER

A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output and other features required of a functional computer. Single-board computers were made as demonstration or development systems, for educational systems, or for use as embedded computer controllers. SBC computers typically provide a fanless, low-power computing solution and a low profile architecture. (wiki)

What Single Board Computer can do?

1. As a SMS Gateway

An SMS gateway allows a computer to send or receive Short Message Service Short Message Service (SMS) transmissions to or from a telecommunications network.

2. As a File Server
We can share files, documents, music, photos with other fellow users at home or in the office as though we had server itself.

3. As an Access Point

By installing a wifi adapter, we can change the SBC as an Access Point.

4. As a Multimedia Player

We can make an old TV become a smart TV by using SBC.

Example of Single Board Computer :

Membongkar Seluk Beluk Rahasia Monitor

Kata - kata "Monitor" sudah tidak asing lagi bagi kita. Monitor adalah sebuah layar yang berguna untuk menampilkan gambar hasil dari proses yang bekerja didalam CPU. Setiap Monitor pun berbeda - beda. "Kenapa sih berbeda - beda? Toh cuma untuk menghasilkan gambar saja". Ya, walaupun hanya untuk menghasilkan gambar, tentu kualitas gambar juga di pertimbangkan. "Jadi, apa aja sih yang perlu di pertimbangkan saat membeli Monitor?"

Yang Pertama, Ukuran Monitor

Ukuran Monitor berbeda - beda, ada yang besar, ada juga yang kecil. "Tapi saya maunya yang sedang - sedang saja". Ada juga kok yang berukuran sedang. Saya jelaskan ya..

Untuk ukuran monitor, setiap jenis berbeda - beda, untuk LCD itu ukurannya sekitar 12 inci - 40 inci (1 inci = 2,54 sentimeter). Ya tentu saja semakin besar semakin mahal, tetapi semakin bagus pula kualitas Monitor tersebut. "Gimana sih cara ngukur Monitor itu?" Untuk mengukur Monitor itu adalah menghitung panjang diagonal layar Monitor tersebut. Lebih jelasnya lihat gambar di bawah.

"Terus LCD itu apa sih?" LCD itu adalah salah satu jenis Monitor. LCD adalah singkatan dari Liquid Crystal Display. Layar Monitor LCD adalah layar yang paling banyak digunakan sekarang. Bentuknya ramping, tidak seperti Layar Monitor CRT (Chatode Ray Tube) yang memiliki bentuk gendut seperti tabung / kotak. Sedangkan plasma bentuknya mirip dengan LCD, tetapi cara kerjanya berbeda. Plasma menggunakan gas mulia, Neon/Xenon untuk memunculkan gambar. Plasma mempunyai gambar yang lebih jernih dan tajam
