Recognize the Laptop's Hardware


1. Wifi / WLAN & Bluetooth
 Almost all laptop brands now apply a combo module for wifi and bluetooth devices, it means that the two devices are combined in one device. Wifi function to exchange information via hotspot network, while Bluetooth is used to exchange information with other bluetooth devices.

2. Motherboard
Often referred to as the Mainboard. A motherboard or main circuit inside the laptop. In motherboard planted a wide variety of main constituent components that can be turned with a normal laptop. The components include: Processor, Chipset, VGA, Bios, etc. The motherboard is the main engine in the computer.

3. Thermal Module
 Most refer to as a fan or a fan. In general, thermal module is divided into two parts, namely: a metal conductor of heat is often called the heatsink or also called heatpipe. While the second part is a fan or a fan that serves to remove the heat out of the laptop.

4. Speaker
 Surely already know if that is, that as the audio output on the computer.

5. Hardisk
 As a computer user data storage media.

6. Baterai
 As a backup power for laptops, so the laptop can be turned without having to connect to the source of electric current.

7. Hinge
 If the previously mentioned hinge picture, it was just casing that covers it. The original form of the laptop hinge is as shown above.

8. Memory 
If the previously mentioned hinge picture, it was just casing that covers it. The original form of the laptop hinge is as shown above.

PC Development

Computer users has grown in recent years. In fact, the number of computers currently estimated to have penetrated a 1 billion units.
Calculated according to Gartner analyst institutions. Each year, Gartner predicts the development of the number of PCs in the world reached about 12 percent.
And if these numbers continue, then in the year 2014 the number of PCs is estimated to be spread jumped to 2 billion units. It was a fantastic amount.
Luis Anavitarte, vice president of Gartner said, developing countries will take more roles in the surge of this PC.
electronic devices"Moreover, governments in many developing countries have committed to minimize the digital divide by promoting more use of PCs to their people, including the layer of lower-class society," he added.
On the one hand, increase in the number of circulating PC can indeed be a positive means of equitable use of technology, but on the other side to consider is the balance of the amount of recycled PCs. Because, if only a waste, electronic equipment is feared will be a waste even be harmful to the environment.
Gartner's own estimates that more than 180 million PCs will be 'removed' owner to be replaced with new ones this year. So you can imagine how much electronic waste that would result if the device is not recycled.

Electronic Computer

Guiyu cities in mainland China is home to a cottage industry of 5500 to process the parts of the electronics used, known as e-waste (electronic waste). Based on data from local sites, the region annually process around 1.5 million pounds of waste consisting of waste computers, mobile phones and other electronic devices. The industry became a lucrative job opportunities for people in Guiyu.


Most mobile phones and old computer equipment can be dismantled and the metal components in it is recycled, but the running of this recycling process is safe requires a very long time.
Therefore many electronics manufacturers are sending out electronic former country, where These tools were burned regardless of Environmental and human health in the vicinity.


Almost 80% of discarded electronic equipment is processed comes from outside China, particularly fromAmerica, the only industrial country that refused to sign the Basel treaty designed to regulate hazardous waste exports to developing countries for recycling.

They chose an electronic trash in Guiyu and other similar places in India and the region Africa, because the cost is cheaper and easier mechanism, where the company is not bound recycling regulations are strict. Of electronic waste processing business, the site Guiyu reported annual revenue of about 75 million dollars.


They are processing electronic waste by separating each section and group them, then
retrieve content of tin, gold, copper and other metals from circuit boards, cables, chips and Another part of the electronic device. In the photo on a worker was heating board computers on the metal layer to strip tin solderan of computer chips.


This small industry employing 10,000 people mostly under-age. Imaginable
result of electronic components that contain mercury and toxins harmful to them.
Medical reports from the area mentioned Guiyu many children who suffer because of the high levels of environmental pollution due to lead. Later reports from Shantou University, Guiyu have high levels of cancer patients caused by the dioxins highest in the world and the increase in cases of miscarriage in pregnant women.


These industries produce a lot of environmental pollution because of waste processed, especially dust from burning coal is directly discharged into rivers and sewers of the city, causing pollution of water wells and ground water.

Seeing the pictures above we may be more sensible and wise in buying and using electronics products, buy that suit their needs and also consider the age of use, which can reduce the volume of waste generated. Purchased products only from manufacturers that produce environmentally friendly products

Electronic Circuit For printed circuit board definition

A rigid, flat board that holds chips and other electronic components. The board is made of layers, typically two to 10, that interconnect components via copper pathways. The main printed circuit board (PCB) in a system is called a "system board" or "motherboard," while smaller ones that plug into the slots in the main board are called "boards" or "cards." See flexible circuit.

Etched Circuits
The "printed" circuit is an etched circuit. A copper foil is placed over a fiberglass or plastic base of each layer and covered with a photoresist. Light is beamed through a negative image of the circuit paths onto the photoresist, hardening the areas that will remain after etching. When passed through an acid bath, the unhardened areas are washed away. The finished layers are then glued together. A similar process creates the microminiaturized circuits on a chip (see chip).

Starting in the 1940s
Printed circuits were first used in the 1940s to connect discrete components together. By the 1960s, PCBs were widely used in all electronic systems, but still mostly connecting discrete components. Integrated circuits (chip) were emerging and added to the boards, and by the 1980s, PCBs were holding large quantities of chips. Today, printed circuit boards typically connect mostly chips with only a few discrete components, each chip containing from a few thousand up to hundreds of millions of transistors. See surface mount, via, discrete component, chip, card and motherboard.


The motherboard is the primary printed circuit board in a computer. The drawing at the top shows a Baby AT style motherboard in a PC. The adapter cards plug into the expansion slots on the motherboard.

Computer

Computer is a tool that is used to process documents according to procedures that have been formulated. The word computer is used to describe people who work to do arithmetic calculations, with or without hearing aids, but the meaning of these words and then moved to the machine itself. First origin, processing information almost exclusively related to the arithmetic problem, but modern computers are used for many tasks not related to mathematics.

In such definition, there are tools like a slide rule, the type of mechanical calculator, to which all contemporary electronic computers. Term better suited to a broad sense such as "computer" is "to process the information" or "information processing system.
