The Difference Between

Decoder convert an input binary code into a corresponding single active output.

you can think of a Multiplexer (switch) as your home systems-it connects data from one of n sources to its output.when you want play movie you select movie on your home system then it switch it to movie..

Internal cache is stored in a reserved area of the RAM of your computer. External cache is also called secondary cache or level 2 cache memory. It is external to the microprocessor and is stored on a separate chip.

In the simple triangular roof truss the load of the pitched roof is supported partly by the sustaining walls and partly by the pull of the horizontal element between the two walls. In the fan truss shown, the same priciple of dividing loads into thrusting and pulling elements is used in order to give better distributionof thrust over the supported area Reduction of the weights and forces on individual members, that cause distortion and deformation can permit the use of less expensive or thinner materials reducing costs.

A welding rectifier is a m/c which converts A.C. supply to D.C.supply. Rectifiers are used for heavy welding work. An invertor is a welding m/c which converts A.C. supply to D.C.supply and then again converts D.C. to A.C. The wt. of invertor welding m/c is less than a welding transformer.

why don't you give us some information

SD Ram is actually SDR SDRAM, and DD Ram is actually DDR SDRAM, though the former does not usually have the SDR in front of it. The letters SDR and DDR stand for Single Data Rate and Double Data Rate, and the letters SDRAM stand for Synchronous Dynamic Random Access Memory. The main difference between SDR and DDR memory is speed. There are a lot of little differences, but the main one (IMHO) that affects the user is speed: DDR can transfer data at roughly twice the speed of SDR. More speedy data rates = better performance. Just remember, the motherboard you are using must include the appropriate chipset to support the different RAM types. They are not interchangeable. SDR SDRAM comes in three main flavors: PC66, PC100 and PC133. Each successive number refers to the bus speed of the RAM in MHz, thus PC66 runs at 66 MHz, PC100 runs at 100 MHz, etc. SDR SDRAM has 168 pins at the connector.

DDR SDRAM has 184 pins at the connector, which is one reason you can't just use DDR instead of SDR, and comes in many different flavors; PC2100 which runs at 266 MHz, PC2700 which runs at 333 MHz, PC3200 which runs at 400 MHz, etc. While the numbers on SDR SDRAM referred to clock speeds, the DDR SDRAM numbers come from the theoretical maximum bandwidth in Megabytes per second (MB/s). Thus, PC2100 has a theoretical maximum bandwidth of 2100 MB/s, but runs at 133 MHz. DDR SDRAM modules are now available from PC1600 all the way up to PC4400, which has a bandwidth of 4400 MB/s and runs at 550 MHz. In order to know which type of RAM you need, you must know what your motherboard supports. I recommend searching the motherboard manufacturer's website for this info, or review sites like tomshardware.com or sharkyextreme.com. Good luck!

For NRZ we require large bandwidth,because transition will not occur in middle of bit.whereas in Manhaster encoding transition will occur middle of the bit so Data rate = Modulation rate/2 Regards, Dilip Prajapati

A new television is not a nondurable, but a durable good. It is a durable good because it has a usable lifespan of more than three years.

duration of iconic memory for about less than one second whereas duration of Echoic memory for about Three to four second- Nilesh Gunjal ( M.A. Psychology)

Man can think and process data himself, while a computer can only process what man programs it to process.

An echocardiogram gives a visual picture of the heart muscle and chambers.

An electrocardiogram (EKG) produces a graph showing the electrical impulses of the heart's contractions. It shows various wave forms of the electrical strength and pattern.

LED tube T8 is much coarser than the LED tube T5

T8 is about 3 cm in diameter ,the diameter of T5 is about 1.5 cm.

LED tube T8 Power : 36W (120 centimeters ) 30W (100 centimeters ) 18W (60 centimeters )

LED tube T5 Power : 28W (110 centimeters ) 21w (88 centimeters ) 14W (55 centimeters ) 8W (30 centimeters )

The distinction between T8 and T5 LED tube lamps, and their advantages and disadvantages :

The difference between T8 and T5 is the thickness , T8 circumference is 8 cm , T5 circumference is 5 cm .

The LED tube T5 has less light decay, longer life, but the lower electro-optic efficiency (the emitted light consuming 1W power ).

The LED tube T8 has the more light fades , shorter life, but the higher electro-optic efficiency (the emitted light consuming 1W power).

The diameter of LED tube T8 is 24MM

LED tube T5 is 16MM in diameter

Regular LED tube T8 diameter is 1 inch , 1 inch = 25.4mm, 25.4mm multiply 3.14 = 80mm = 8cm, ie 8 cm .LED tube T5 is 5cm

To be precise all dialog boxes are windows, but, a dialog is one that requires input from the user such as the Print dialogue and remains in front of the application window until cancelled or completed unlike a new email window which can be minimised. In addition to this, The basic difference between a dialog box and a window is: 1. A dialog box expects immediate response from the user. However, a window does not expect immediate reponse. Moreover, a dialog box closes to process user reponse. This is not the case with a window. 2. A window consists of minimize, maximize, and close buttons on the right end of the title bar.

On the other hand, a dialog box only consists of help and close buttons on it title bar. 3. A dialog box consists of OK and Cancel buttons on the lower right corner.

A window, on the other hand, does not consist of such buttons.

You are preparing for an outbreak of 'salmonella food poisoning'. Devise an outline policy, a procedure and a protocol that you would find useful in this situation. What are the main differences between them

LGA : Land Grid Array <== pins are in the socket, no pins are attached on the CPU, only pads.

PGA: Pin Grid Array <== pins are attached on to the socket, the socket has some sort of "holes" that hold the processor

A microphone translates a sound wave into an electrical impulse, and a speaker translates an electrical impulse into a sound wave.

The difference between a backlit keyboard and a regular keyboard is that backlit keyboards, are able to be used in pitch darkness because it lights up from behind the keys. On regular keyboards the characters attributed to each key are simply printed on and do not light up. This makes backlit keyboards the ultimate in versatility.

There isn't really a difference but you can also do reg calls on skype

Telecommunications is a word for all communications over a distance by cable, telephone, telegraph or broadcasting. Teleprocessing is computer service in which terminals are connected to a central computer.

An embedded system has a self-contained operating system on a "chip" thus embedded into the system and does not rely on having a hard disk with the operating system on it. Not to mention that is will be much faster because the access time of the OS on a chip.

More specifically...

An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software.

A PC is designed to be a general purpose computing environment.

Many of today's embedded systems are looking more like PCs with user interfaces, touchscreens, displays, keypads and more. Still, these are not general function systems but are designed to perform very specific functions.

The ALU (Arithmetic-Logic Unit) is generally a subsection of the CPU (Central Processing Unit). While the CPU is the master driver of a computer, the ALU is a processing area optimized to handle mathematical computations and logic comparisons. The processor controller passes operation codes and operands to the ALU, which performs the requested operation on the supplied data and passes back the results.

broadcasting is the process of sending information (ex:video signals or tv programs) to distant places is called broadcasting

but where as telecasting refers to broadcast (ex:tv programs) the programs on television i.e. the broadcasted information.
