Kinds Computer Operating System

Various Kinds Computer Operating Systemcomputer will only work if your computer has installed the operating system, we probably only heard of 2 or 3 major OS in the world such as Windows, Linux and Mac OS in fact there are several more that we do not know might never even tried it. Kerana so far we only recognize the Windows operating system with its windows series

I explained the following types of computer operating systems, including:
- WINDOWS (MICROSOFT WINDOWS)
Mircorost Windows or the computer operating system developed by Microsoft Corporation that uses an interface with berbasikan GUI (Graphical User Interface) or bergrafis interface. when first introduced, the Windows operating system became the first graphics-based computer that Microsoft created and successfully took the hearts of computer users in the 80's
- UNIX
UNIX is a computer operating system created by Ken Thompson and Dennis Ritchie, developed by AT & T Bell Labs. UNIX is a computer operating system that initiated the emergence of Linux dipentas operaso system. The creation of UNIX began when in 1965 the experts Labolatoris Bell Telephone (Bell Labs) belonging to AT & tT in collaboration with General Electric and the Mac Project of MIT to make the operating system called Multics.
- LINUX
Linux was originally just a kernel or heart of a computer operating system created by Linus Torvalds in 1991, initially just a terminal emulation required to access the UNIX servers at the university. Linux is the cloning of MINIX (One variant of UNIX), system tools and libraries usually come from the GNU Operating System
- IBM OS / 2
computer operating system IBM OS / 2 was created jointly by the International Bussiness Machines Corporation and Microsoft Corporation, for the purpose of use on IBM computers as a replacement for the DOS operating system. Said OS / 2 is the acronym for Operating System / 2, the operating system is designed to be fully capable of using Intel 80286 microprocessor, including the Protected Mode (Protected Mode), able to perform tasks simultaneously, and supports Virtual Memory, while maintaining compatibility with many MS-DOS software in circulation at that time
- FreeBSD
FreeBSD is a UNIX-type operating system computer-derived free UNIX AT & T. T through the branches of the Berkeley Software Distribution (BSD) is 386BSD and 4.4BSD operating system, FreeBSD running on Intel x86 systems. FreeBSD itself first appeared in 1993 by David Greenman. The goal of the FreeBSD is to provide software that can be used for various purposes. FreeBSD 386BSD itself was developed from a development project in BSD OS that runs on Intel chips
- SOLARIS
Solaris computer operating system is a computer operating system based on UNIX system that allowed by Sun Microsystems in 1992 as a supporter oada SunOS. Solaris is famous for its stability, especially on the system SPARC (Scalable Processor Architecture).
- CHROME OS
Google Chrome OS is a computer operating system designed by Google Inc.., Working exclusively with web applications. Google Chrome OS announced on July 7, 2009, and the stable version of Chrome was launched mid-year 2010.Google OS based on Linux and will only run on the hardware that is specially designed.

Signs in a state machine overheat and how to prevent it

Engine is the cornerstone of every type of vehicle, including motorcycles. If your engine quickly overheated as soon looking for the cause, because if it can not be your motor can not walk anymore.
Signs in a state machine Overheat : 

- Appears smell burnt or rice pest in the engine

- Motor loses power 

- In recent years motor output, there are indicators of the machine, if the engine is too hot indicator lights up.

Here's How to Prevent Heat Machine Racing
1. Change oil regularlyajin and discipline replacing engine oil. The reason, besides the oil serves to lubricate the engine components are also cool the components when they rub against one another.
2. Use the right oilUse the oil that is consistent with the specifications and your driving style. Some sources mangatakan that with 10w40 viscosity oil is relatively more rapid heat release when compared with oil with SAE 20w50.
3. Check the distribution of oilOil serves to lubricate eleman element that is in the machine, make sure your motor oil can be distributed properly.
4. Make sure the Piston Position Not Too MeetingThe position of the piston (located in the cylinder liner) that is too tightly will cause the piston and the piston could not freely stir aka jam. Not only will it make your bike fast heat machinery but also will damage the piston or engine block.
5. Replace the coolant fluid regularlyIf the bike uses a liquid cooling system, then replace the coolant fluid regularly. Minimum of once a year.
6. Routine Cleaning the RadiatorIf your motor is a motor that uses air cooling system, so be diligent to clean the radiator.
7. Make sure the fins and the Cylinder Head CleanerMake sure no dirt on the cylinder and cylinder head fins that can inhibit the release of heat engines.
8. Add Heatsink With FanWhen the motor has reached the age of five years, so it's good add to the radiator with a fan. Placement can be in front or behind the radiator.
9. Use Cold type Spark plugThere are so many brands on the market that type of cold plugs. Also called normal or racing spark plugs. Prices vary, usually priced above Rp.50ribu.
10. Open leg-shield (gaiters)If your bike has a leg-shield (gaiters) as at Satri FU then better off. With the opening leg-shield, was allegedly going to launch air flow in the engine. So the machine easier to remove the heat.

TORQUE AND POWER

Torque Components

Torque is the force press play on the rotating part. Motorcycle driven by a torque generated crutch. Torque can be calculated through the formula

T = Force x Distance

If the force F (kg) employed to rotate the object along the R (m), to tighten the bolt mass, then the torque used is FR (Kg m), as changes in torque from the primary reduction between the crankshaft primary gear with the clutch teeth secondary house, channeled to primary teeth on the gear transmission of secondary transmission, then connected to the primary tooth final gear forwarded through the chain on the final secondary gear teeth to be able memutra rear wheels.If a torque F works on gears A with radius r, associated with the gears B with radius 2r, the torque on gears B despite the greater the rotational speed is reduced into half.

In the machine!

The length of the piston step is twice the distance of the center of the crankshaft to the big end (crank pin), explosion produces compressive force the piston to push the piston down until then rotate the crankshaft. Therefore the engine torque will change according to the magnitude of the force generated (F) for a fixed distance. The size of the force F is changed according to engine speed, this means influenced by the efficiency of combustion, it helped change the amount of torque.

Digital Torque Meter

In fact the performance of any engine has a saturation point, at a specific velocity, peak torque (maximum torque). But kenanikan next engine speed will not increase the torque.When the motor operates at maximum torque round the rear wheel force also the maximum spin. How to increase the torque, there are two ways: increase the resulting explosion pushing the piston engine to be able to more quickly, or extend the pistons move.

Power

Average performance is measured by time. Crankshaft torque drive a motorcycle, but this is only the force to drive the speed of the motorcycle was not taken into account. Power is work which can lead to speed.

Power = Work / Time. Kg, m / sec

Unit of power expressed in PS (Pferd Starke-GERMANY) or 75 kg.m / sec, meaning that these workers were able to move objeck weighing 75 kg with a mass of 1 meter in one second, the greater the engine's ability to move objects in a unit time, it means the the greater the power output. The more the total weight of the vehicle and rider, it also requires more power to achieve the same speed.

Generating a large torquePower at crankshaft can be measured with the formula,

Q = 0.0014 NT

 
Where N, is the engine rpm, and T is Torque. Engine power output will vary depending on the torque generated by the engine speed, the higher the engine speed, the greater the power. Therefore at a certain speed, the torque starts to decrease.When the energy reaches maximum, this is called "Maximum Power" and at some point will reach the peak point of exhaustion until engine speed is no longer able to raise power.

Selecting and Using Appropriate HID Light

What never occurred to you to replace the lights on your bike or car with the lights brighter? If yes, then the HID lamp can be one answer. High Intensity Discharge Lamps (HID) or commonly called Xenon lamp is currently a trend, both in four and two wheeled vehicles. Understandably, with bright lighting power and high durability, the lamp was chosen automotive manufacturers.

HID LIGHT

But to use it needs some consideration. Aki is overdrawn or electrical system problems can be a big problem. Also worth considering is the presence of light that sometimes inviting danger to other motorists or themselves. Therefore, light emitted from the light cause glare that are too large. Therefore before you use it, you also must consider the factors of functional or usability of the lamp itself.

This article will provide tips on how to choose and correctly install the HID lights?

1. Be sure to choose the right type
Currently on the market has been sold to the quality of the types and brands of HID lamps. Therefore, please choose carefully before you insert it in the vehicle. Several types of HID lamps on the market, including H1, H3, H4, H7, H8, H11, HB3, and HB4. Differ from one another on the bulb holder.

2. Make sure the type and strength of the light produced

After selecting the type that has the same seat with a light bulb factory default on your bike, then choose the type of light emitted. The size of the resulting light levels specified in units of Kelvin.
One thing worth noting, the higher the Kelvin the brighter the lights anyway. "However, the brighter the light, instead of making things look more clearly at night,"
Therefore, consult a mechanic at the garage or in a store where you purchased the lamp. Usually, the type that has been chosen is a bluish-white or yellowish white.

Light from HID lamps

3. Make sure the battery and electrical system motor is not problematic

Another thing you should also take into account before installing the HID lights is the electrical system of your motor. Check back starting from the battery, motor battery charging system, and how much electrical current is needed.
Because at first HID lamp is switched on, requiring a large stun currents. After that, the new standard with a constant magnitude. "When the battery is worn out or old age, then chances are very high drop battery," So in addition to potentially faulty lights, motorcycle batteries and electrical system was problematic. In order to balance the electrical current which sucked the light is not a problem, do not forget to choose the HID lamp ballasts are fitted.

4. Make sure the house lights and reflectors in accordance with the type of lamp

When the electrical system is no problem and is ready to accept the presence of HID lamps, the next step is to ascertain whether the house lights, including the bulb holder and reflector are not problematic. Because the HID bulb has a greater heat flow than ordinary bulb.

HID lamps

That way, not infrequently bike reflector lamp that uses this type of lamp melted from the heat, at least the lights will be dim. As a result, the use of HID lamps were no different from ordinary light.

Car Engine Overheat

Have you ever experienced a fast machine heat on your car? Keep in mind that if the car is already very high temperature, immediately turn off the engine, because if the machine is 'forced' to live, would be fatal consequences. Ideally, the engine temperature is 80-90 Celsius. However, you do not need to measure it, you just see it easily through the existing temperature indicator on your car. The temperature of a hot car engine due to several factors, one of which is from the radiator .. Here are tips to overcome the causes of car engine temperature rises due to the cooling function can not work normally:

Radiator

1. Check the radiator. Open the radiator cap and see if the water in full condition. If less immediately added. Do not forget to check the cap, the radiator grille. See also whether the radiator is leaking or not.








Radiator hoses

2. Check Radiator Hoses. Check the radiator hose from the possibility of rupture, clamps are less tight because it will cause the temperature gets hot.

Radiator tank

3. Check the Radiator Tank. Check the radiator water reserves in reservoirs. If less water added to the upper limit if the water is too dirty and immediately replace it with clean water and added Long Life Cooland.

Water Pump

4. Check for Water Pump. Do check water pump with a view of the underside of the vehicle or if possible Raise the vehicle and look at the water pump there is a vent below. Check if there is water coming out of the hole. If there is immediately to the garage to do a new water pump replacement.
