The engine of the car can be too warm in all weather conditions and temperature. Changes chemical energy into fuel to heat energy by combustion of fuel needed to run the car. If this process is not monitored and controlled, then overheating may occur.
High temperatures can damage and burn a hole in the part, damage to the rings, pistons or rod bearings or head gasket blows. Unfortunately, some machines are made with aluminum heads or other parts that may be sensitive to higher temperatures than normal. Contrary to popular belief, refrigeration does not always save your engine if overheating occurs. If the coolant in your car starts to cook the old radiator hose or maybe burst, the piston can swell and intervene in a boring or your exhaust valve stems may be connected or abrasions on their guidance.
Some of the main causes of overheating include:
* Low coolant or coolant leakage
* Poor heat conduction in the engine deposits caused by water jackets
* Poor flow of air through the radiator
* A fan clutch slip
* Non-electric fan
* A broken radiator hose
* A loose or eroded impeller of the pump
* Dragging brakes
It is important to immediately cool down after your car and you see the temperature or light indicates that your vehicle is hot let. If you do not, you run the risk of blowing your engine. It may take more time to sit and wait fot the cold, but will more than likely significantly reduce the cost of repairs.
It’s also a wise idea to the heater at full speed, because most heat from the engine. In addition, you can try putting the car in neutral and rev the engine at idle speed. If this action does not help cool the engine, there is probably a bigger problem than a simple overtime and you should consult a professional.
As a technology, analog is the process of taking an audio or video signal (human voice), and translated into electronic impulses. Violation of the second digital signal into a binary format where the audio or video data represents a series of “1” s and “0” s. Quite simply, if the device is an analog or digital telephone, fax, modem, or wise, that not all the converting for you.
Digital vs analog indicate that the method of input, data storage and transfer operation of the internal device, and the nature of the display. The word comes from the same source as the word and the number DIGITUS.
The digital technology breaks your voice (or television) signal is a series of binary 1 and 0 at the other side, where another device (phone, modem or TV) takes all the numbers and putting them in the original signal. The beauty of digital that he knows what must be, if at the end of your transmission. Thus, if a fault occurred in the data transfer. What does this mean for you? Clarity. In most cases you’ll get distortion-free conversations and clearer television images. The nature of digital technology makes it possible to cram together many of those 1 and 0 in the same space an analog signal. As a button-rich phone at work or in the 200-plus digital cable service, means that multiple functions crammed into a digital signal. Digital offers better clarity, but analog gives a richer quality. Like a digital VCR or CD is the cost of everything from cell phones coming out and the satellite dishes.
The digital telephone lines are big business. Though digital lines carry lower voltages than analog lines, still pose a risk to the analog equipment.
The analog lines are also known as POTS (Plain Old Telephone Service), support standard phones, fax machines and modems. These lines, which are characteristic of your home or small office
There are digital-analog adapters that not only allows you to use the analog devices in the digital environment, but also protection against frying the internal circuits of the telephone, fax, modem or laptop.
The nature of digital technology, breaking the mark of a binary code and recreating the host endgives it clean, distortion-free wireless calls.
Cordless phones, digital technology is able to encrypt every 1 and 0 during the transfer, so the conversations secure from eavesdropping. Plus, more power can be applied to digital signals, so you will have a wider range of wireless phone conversations to enjoy.
The advantage of the analog cordless products? Well, they are a bit cheaper. And the sound quality is richer. So, if the digital security, why not save a few bucks and go with an analog phone line? Indeed, in the home or small office environments where you may be the only wireless user, you will not be disturbed.
Keep in mind when talking about the digital and analog cordless phones, talking about the transmission of signals between the handset and the base. The phones themselves are analog devices, which are exclusively on analog lines. The range of analog or digital wireless phone is always willing to depend on the environment.
Perhaps the most effective against the analogue to digital technology in the growing mobile market. Activate the new phone is growing exponentially, quickly realized the limits of the analog.
Digital cellular lets significantly more people use their phones to a coverage area. Further information is transmitted and received simultaneously on all telephone users. Plus, transmissions are more resistant to static and signal fade. And the all-in-one nowphone phones, pagers, voice mail, internet access, digital phones with more features than the analog predecessors.
The analog sound quality, some users still superioras dual transfer switch in the right-hand phones with analog sound, when not busy with a full coverage areabut digital is quickly becoming the standard in the mobile market.
Digital provides better sound quality. Supporters of digital claimed too that because digital scrambled up the signal bursts, it is more secure than analog and can help to thwart “cloning” an act of grabbing phone account information over the air, and then copy the sales data for the purposes of piracy. Some industry estimates, nearly $ 650 million in wireless services to their large ears coveted criminals, adding that the bottom line of the operating costs are eventually transferred to the buyer. Digital battery is stronger than analogue, and most, better, more advanced phone services.
The energy that we often use more and more reduced or depleted. Because of the wide use of uncontrolled, giving rise to the scarcity or even die out. For that now needs to consider the alternative energy instead of energy which is usually often used. The following are the various alternative energy sources that can be utilized, in addition will help the air to be clean, the savings also will be done.
Wind. Kinetic wind power is now already widely used as a wind player using wind turbines for home or for business purposes. Just one turbine can support up to thirty houses, but because the wind is always blowing, backup power must always remain available.
Sun. Sun-rich tropical countries seem to be very suitable to use this resource. Try using a roof made of solar systems are called photovoltaic cells.
Biodiesel. The basic ingredients of this fuel made from plants like soy, coconut and the like, biodiesel is non-toxic fuel that can be blended with regular diesel or used as is to reduce emissions.
Nuclear. With uranium fuel, metals found in rocks, and processed in a nuclear reactor, the heat energy will be used as an ingredient to turn turbines that exist. These energy sources do not release greenhouse gas emissions. 20% of the power source in the U.S. have nuclear fuel.
Hydrogen. How do you create a resource that did not remove anything but clean water? The answer is hydrogen fuel cells. The problem now is to separate hydrogen from a composition, such as carbon chain or water, means using other resources. Storage of hydrogen is also not easy, because its density is very low, it is very difficult to put hydrogen in large quantities in a narrow room. Hence, although many vehicles began using hydrogen as fuel, it is still difficult to set up hydrogen filling stations.
BANDUNG, KOMPAS.com – It was a chance the developer Indonesia to host the applications market is huge. Nineteen mobile game applications generated from the workshop for two weeks by people who are still studying the technique of making such applications.
According to a press release received from Agate Kompas.com Studio, the 19 th of the application is made by novice developers who participated in workshops (workshops) making a game that made Nokia and Agate Studios in Bandung.

Computer networking is a system which consists of computer and other network devices that work together to achieve a similar goal. They formed a communication between the computer to:
a. Using of data, resources and others
c. Access information, etc
To achieve the goal of computer network services, there is the request service (client) and service provider (server). This system is called client-server network.
Computer network be formed by connecting the computer using the cable media (cabling) is arranged such that a form of architecture / model relationship between the computer is called topology. The type of network topology is as follows:
computer servers and workstations connected in sequence via a single cable. This topology is simple and easy to develop, but when one workstation experiencing problems then the other will be affected.
This topology is similar to the bus topology, ring topology difference between each other as if the end form a circle ring. On this topology data flow direction, that means all of the computers in the network will participate in the process through which information, so that when one is broken it will affect the entire network.
In this topology, each computer is connected directly through intermediaries such as media hub / switch. In practice, development of a network does not usually use only one topology, but some combination of the existing topology.
Relationship between devices where each device is connected directly to another device on the network. As a result, in a mesh topology each device can communicate directly with the destination device.
Like the star topology, the device (node, devices) in the tree topology is also connected to a central control (central hub) is working to set up traffic in the network. However, not all devices in the topology tree is connected directly to the central hub. Some devices are connected directly to the central hub, but the other is connected through a secondary hub.
After reading the above description, try to answer some questions below:
1. Search information about the shortage and surplus if using the mesh and tree topology
2. Eearch information about the cabling techniques in star and tree topology
