what is the difference between a ram jet and a turbofan?
341437
A ramjet does not have any blades (or any other moving parts for that matter)\n\nIt works by air entering it at high speed (ramming it in!) and igniting it.

turbos are driven by the exhaust gasses, superchargers are driven off the crank. turbos have higher power potental but they have to spool up, so there is some lag in the low end, commenly called turbo lag. superchargers are always on and have exellent low rpm responce but they don't have the peak power potential of a turbo or the high end power. niether one causes damage (to the car, if thats what you mean) if the proper measures are taken.

If the 370hp Ram is rated at 370 at the motor and not the wheels then yes, if the hp is rated at the wheels then again it's gonna be close, as both trucks are heavy anyway.\n\nWhere are you at, I know of a certain 2002 Chevy that would put some $$$$ on the line, it's just a lil' ol' VORTEC; ) surely no match for the big bad HEMI.  If you're close to Ark. give me a holler, it can be arranged.

Do not confuse the term DDR or DDR2 with DUAL CHANNEL.\nThe 2 are unrelated.\nIt's not the RAM which is dual channel...dual channel is a mode the motherboard operates in to increase ram speed.\nA dual channel "kit" of ram simply ensures that the 2 sticks of ram in the kit have been tested to be of identical speed so as to guarantee proper operation on a dual channel mode board.\nGenerally, any 2 sticks of ram of the same size and speed should run in dual channel mode, but because ram speeds can differ slightly between say 2 different batches or "runs" of say PC3200, occasionally you may run into timing issues with modules that were not specifically matched to each other.

Turboprop Engine Glenn\nResearch\nCenter \n\n\n       \n\nTo move an airplane through the air, thrust is generated with some kind of propulsion system. Many low speed transport aircraft and small commuter aircraft use turboprop propulsion. On this page we will discuss some of the fundamentals of turboprop engines. The turboprop uses a gas turbine core to turn a propeller. As mentioned on a previous page, propeller engines develop thrust by moving a large mass of air through a small change in velocity. Propellers are very efficient and can use nearly any kind of engine to turn the prop (including humans!). In the turboprop, a gas turbine core is used. How does a turboprop engine work?\n\nThere are two main parts to a turboprop propulsion system, the core engine and the propeller. The core is very similar to a basic turbojet except that instead of expanding all the hot exhaust through the nozzle to produce thrust, most of the energy of the exhaust is used to turn the turbine. There may be an additional turbine stage present, as shown in green on the diagram, which is connected to a drive shaft. The drive shaft, also shown in green, is connected to a gear box. The gear box is then connected to a propeller that produces most of the thrust. The exhaust velocity of a turboprop is low and contributes little thrust because most of the energy of the core exhaust has gone into turning the drive shaft.\n\nBecause propellers become less efficient as the speed of the aircraft increases, turboprops are used only for low speed aircraft like cargo planes. High speed transports usually use high bypass turbofans because of the high fuel efficiency and high speed capability of turbofans. A variation of the turboprop engine is the turboshaft engine. In a turboshaft engine, the gear box is not connected to a propeller but to some other drive device. Turboshaft engines are used in many helicopters, as well as tanks, boats, and even race cars in the late 1960's.

they are basically the same\n\nits what aftermarket parts that you put, that really matters.

well first of all RAM is random access memory so it can access data randomly not sequentially like in hdd that's y it works fast.\n  second property of RAM is that it is voletile that mean all the data will b removed from it as soon as u will put off the power supply so u can use a 4erased for fast data access but ur data will be stored till power supply is on , as soon as u will put off the power data will be earased

Normally when car manufacturers are talking about just HP, they are talking about the horsepower the engine makes at the flywheel. Wheel HP on the other hand is the measurement of horsepower at the wheels. Between the flywheel and the drive wheels, horsepower is lost in components such as the transmission and the differential. So the HP an engine makes at the flywheel is always going to be higher than the horsepower reading at the wheels.\nAnd when it all comes down to it, the horsepower made at the wheels is what really moves the car.

If you want to install RAM into your computer more is better. RAM chips are available in sizes up to 2GB. Size is only one feature of RAM though. Next is RAM speed. RAM that comes in the same size comes in a variety of speeds. RAM speeds are based on MHz. The higher the MHz the faster the RAM. You should also know that if you install two RAM chips on your PC that are of different speeds the computer will run both RAM chips at the speed of the slower chip. \n\nOther considerations are new RAM technologies. There are three types of RAM chips. SDR SDRAM (Single Data Rate Synchronized Data Random Access Memory - Slow RAM), DDR SDRAM (Double Data Rate Synchronized Data Random Access Memory - Medium Speed RAM), and DDR2 SDRAM (Double Data Rate 2 Synchronized Data Rate Ram - High Speed RAM). Dual Channel RAM is also available. Dual Channel RAM is better than non-dual channel RAM however I don't know much about it except that it only works with two exactly identical dual channel RAM chips.\n\nThe big mistake everyone makes when purchasing RAM is not checking the compatibility of the RAM with their motherboard. Certain motherboards can only handle certain types of RAM. Find out what type of motherboard you have then find out how much and how fast the RAM is that it can handle and buy the best you can install on it. Contact the manufacturer of the motherboard you have for such information.\n\nPS: Please select my answer as the best answer. Thank You.

Corsair is very high quality ram. I use it in my own computers.\n\nCorsair makes both DDR and DDR2. Either should serve you well. Technically speaking, DDR2 (currently on the intel side) is a little better than DDR (AMD or Intel). But the AMD procs are much better.\n\nBottom line? Pretty much any corsair ram is good for gaming, but for hardcore gaming just get some of the Corsair XMS series.

NO! they are different.\nthe motherborad is more like a 'circuit holder'\nhowever the processor, which is fitted into the motherboard, is the 'brain' of the computer. It takes care of all teh timing requirement, memory management, and various other operations crucial to the working of the comp.

Usually if you take the RAM out of the computer, there is a sticker on it that will list the specs of the RAM.\n\nIf you are not comfortable opening the case, you have a program called "MSINFO" on most computers.  Go to C:&#92;Windows&#92;msapps&#92;msinfo" and run the MSINFO program.  This will give you many stats about your computer, including the RAM speed and type.

DIMM's are dual in-line memory module. SIMM's are single in-line memory modules.\n\nThe main difference between SIMMs and DIMMs is that SIMMs have a 32-bit data path, while DIMMs have a 64-bit data path. Since Intel's Pentium has a 64-bit bus width, it required SIMMs installed in matched pairs in order to use them. The processor would then access the two SIMMs simultaneously. DIMMs were introduced to eliminate this inefficiency. Another difference is that DIMMs have separate electrical contacts on each side of the module, while the contacts on SIMMs on both sides are redundant.\n\nRIMM's are Direct Rambus DRAM or DRDRAM (sometimes just called Rambus DRAM or RDRAM) is a type of synchronous dynamic RAM, created by the Rambus Corporation. They're the same thing as DIMM's, except they're faster, and have built in error checking. They were very expensive at first, and no major computer manufacturer uses RIMM's.

A turbojet engine is the simplest type of jet engine. It uses the high velocity of the exaust gases to generate thrust\n\nSites regardin Turbojet enhines and their working:\n\nhttp://en.wikipedia.org/wiki/Turbojet\n\nhttp://www.grc.nasa.gov/WWW/K-12//airplane/aturbj.html\n\nA TurboFan engine is the modified form of the turbojet engine. It has a fan in the front which is rotated with the help of a turbine connected to it. The hot exaust gases rotates the turbine which in turn rotates the Fan. The fan in turn pushes the air backwards and generates the major thrust. These type of engines are preffered in high speed passenger aircrafts as they can perform well in high altitudes and are quieter compared to turbojet aircrafts. They are also more fuel efficient than Turbojet aircrafts.\n\nSite regardin Turbofan Engine:\n\nhttp://www.grc.nasa.gov/WWW/K-12/airplane/Animation/turbtyp/etfr.html\n\nThe followin site contains description of diff types of jet engines:\n\nhttp://inventors.about.com/library/inventors/bljetenginetypes.htm\n\nHope this helps
