What is Single accumulator CPU organization?
An accumulator machine, also called a single accumulator organisation , or a CPU with accumulator-based architecture, is a kind of CPU where, although it may have several registers, the CPU mostly stores the results of calculations in one special register, typically called "the accumulator". Historically almost all early computers were accumulator machines; and many microcontrollers still popular as of 2010

What is fetching in microprocessor?
1) Fetch is the first of two stages involved in computer processing. The processor operates by processing instructions in what is called the "fetch/execute cycle." The processor fetches (reads from memory) an instruction and then, depending on the instruction, executes it (takes some further action with it, such as shifting bits to the right or left). Then it fetches the next instruction, and so forth.
Is it better to have a 1.5 GHz dual core processor or a 3.0 GHz?
the 1.5 dual core can handle 2 threads at the same time and 3.0 single core can only handle 1 thread both of them switch threads rapidly if you have CPU-z you will find that the only difference in number of threads (the number of cores in single core is 2)
short answer : the dual core is faster in multitasks
the single core is faster in single task (like most of games)
What is the role of CPU in the computer's functioning?
The CPU is the 'brain' of the computer. It is where all the searching, sorting, calculating and decision making takes place. The CPU contains a tiny quartz clock. Each time this clock 'ticks', one instruction can be dealt with by the CPU. So the more times this clock ticks per second, the more instructions the CPU can carry out and the faster things get done.
The speed of the CPU is measured in either Megaherts (MHz) or more commonly now in Gigahertz (GHz). A 1 MHz CPU can carry out one million instructions per second. A 1 GHz CPU can carry out 1 billion instructions per second!
A typical CPU installed in a computer today would run at around 3 GHz.
What is the difference between normal system and server?
While a server and desktop system are similar, servers typically have higher-capacity and faster hard drives, faster processors, more RAM, and better networking capabilities than a desktop system. This is like asking "what's the difference between a personal auto and a taxi or a police car?" At one level, it's how they're used. If you license a personal car to carry passengers and use it that way, it's a taxi. If you paint it blue, put a light bar on the roof and then police officers drive it on the job, it's a police car. However, if you know up front that a vehicle will be used as a taxi or a police car, you get it with upgraded or specialized equipment. Those aren't required in principle, but they make a huge difference in practice. It's the same with servers. You can use just about anything as a server, but for serious use you need upgraded components in several areas. These ain't cheap, but they're worth it. Some computer manufacturers sell servers through different channels that most of us buy our PCs, too. These channels typically provide a higher level of support, geared to the technically competent user, but again it ain't free. Is this required in order to call something a server? Not at all. Do most people who buy servers find it worthwhile? You betcha.
What function does the CPU perform in a personal computer?
CPU stands for central processing unit. Overall a personal computer can be divided into the following major parts from point of view of functions performed:
1. Input devices (keyboard, mouse)
2. Output devices (monitor which displays the output or results of work being done on the computer)
3. CPU (central processing unit, which is the brain of the computer which does all the processing and calculations on data inputs and provides output on screen or printer)
4. Storage devices (memories, hard disk which store data).
Many times in common language the CPU term is used for the computer box unit which contains motherboard, processor, hard disk, CD/DVD and floppy drives. This is the box to which we connect monitor, keyboard, mouse and printer through cables. In technical terms the term CPU is used only for the processor, which fits on the motherboard.
Central Processing Unit (CPU), in computer science, microscopic circuitry that serves as the main information processor in a computer. A CPU is generally a single microprocessor made from a wafer of semiconducting material, usually silicon, with millions of electrical components on its surface. On a higher level, the CPU is actually a number of interconnected processing units that are each responsible for one aspect of the CPU's function. Standard CPUs contain processing units that interpret and implement software instructions, perform calculations and comparisons, make logical decisions (determining if a statement is true or false based on the rules of Boolean algebra), temporarily store information for use by another of the CPU's processing units, keep track of the current step in the execution of the program, and allow the CPU to communicate with the rest of the computer.
A CPU is similar to a calculator, only much more powerful. The main function of the CPU is to perform arithmetic and logical operations on data taken from memory or on information entered through some device, such as a keyboard, scanner, or joystick. The CPU is controlled by a list of software instructions, called a computer program. Software instructions entering the CPU originate in some form of memory storage device such as a hard disk, floppy disk, CD-ROM, or magnetic tape. These instructions then pass into the computer's main random access memory (RAM), where each instruction is given a unique address, or memory location. The CPU can access specific pieces of data in RAM by specifying the address of the data that it wants.
As a program is executed, data flow from RAM through an interface unit of wires called the bus, which connects the CPU to RAM. The data are then decoded by a processing unit called the instruction decoder that interprets and implements software instructions. From the instruction decoder the data pass to the arithmetic/logic unit (ALU), which performs calculations and comparisons. Data may be stored by the ALU in temporary memory locations called registers where it may be retrieved quickly. The ALU performs specific operations such as addition, multiplication, and conditional tests on the data in its registers, sending the resulting data back to RAM or storing it in another register for further use. During this process, a unit called the program counter keeps track of each successive instruction to make sure that the program instructions are followed by the CPU in the correct order.
Most common and slowest expansion bus?
As of right now, the fastest expansion bus found in a standard PC is a PCI-E or often seen as PCIe (PCI-E or PCIe stands for Peripheral Component Interconnect Express)
Installing a PCIe card into your PC may be done only if the motherboards expansion slot will fit it. PCIe cards can fit into larger slots, but not smaller slots (obviously).
What is faster Intel core 2 duo processor T6500 or Intel Pentium processor T4200?
Not exactly. The T2330 is almost the same as the T5250 except for a few things. The T2330 has only 1mb of L2 cache(as opposed to 2mb on the T5250), and actually has a higher clock speed at 1.6ghz(the T5250 is 1.5ghz). The T2330 can actually perform a bit faster than the T5250 in certain processes, but for the most part should perform about equal to the T5250. The lack of cache isn't noticeable in everyday usage and only really shows if you have multiple(more than 5) programs open and going at full load, or are running very demanding games. Even then, the difference isn't on a large scale. For comparison's sake, the T5250 has a 667mhz Front Side Bus and a 9x multiplier while the T2330 has a 533mhz FSB and a 12x multiplier. Both have a TDP of 35 watts, are built on 65 nanometer process, and are Merom cores(Merom-2M cores, specifically). They are actually made from the from the same silicon imprint, but after manufacturing are differentiated by either defects in cache or some other problem causing them to not express full capability, which would be a T7250. "Pentium dual core" has become Intel's economy line name, however it's every bit as much a Core 2 Duo as an officially labelled C2D, except for half the cache.
What is the size of the accumulator of a 64bit processor?
The size of the accumulator is the same,means 64bit.
Why you call microprocessor as a microprocessor?
The emitter of a transistor was placed a micrometer distance between two, so it was called a microprocessor. Technology advanced, and the distance was improved to nano meter. Still, they call it micro.
What is an example of a bottleneck effect?
A road with a lot of traffic on such as a motorway and that has four lanes has two lanes closed and thus the traffic piles up as there are four lanes of traffic trying to fit through two lanes. Like pouring water out of a bottle. When you tip it upside down the water sloshes over to the neck of the bottle but piles up and takes time to drain from the bottle rather than a bucket where the water is drained instantaneously.
What goes between a CPU and heat sink?
Heatsink compount or special heat pad. The reason for this is to form a tight thermal bond between the processor (CPU = Central Processing Unit) and heatsink for the best transfer of heat away from the CPU.
The virtual memory addressing capability of 80386 is?
NONE! The 80186 was an advanced version of the 8086 but did not include support for virtual memory. It had a 64K physical address space. The 80286 was the first Intel CPU to support virtual memory but it's capabilities were limited.
Which item help maintain even contact and heat distribution between the CPU and the heat sink?
A good heat sink compound, often known as thermal grease, will provide an inexpensived, readily available, and reliable solution to both the need to maintain even, overall contact between the CPU device's heat-radiating surface and the heat sink itself as well ensuring proper transfer of the heat generated by the device's operation. Typical heat sink compounds are formulated from silicone and are the type most-often recommended by manufacturers and maintenance organizations (primarily due to superior performance and operational life), but there are a variety of types available, produced from petroleum derivatives as well as other substances. Any of the types available for public use tend to be a bit "messy" to work with, at least for the novice; it is for this reason that handy "syringe-style" applicators are popular sellers. A thin coating should be applied to the CPU device's heat-radiating surface (some authorities maintain that it is best to apply thermal grease BOTH there as well as to the heat-sink contact area); any excessive amount that becomes extruded out beyond the contact areas of device and heat sink once the two are firmly attached by the latching device employed in a given configuration will fail to enhance the desired effect of heat transfer, and upon occasion can actually cause problems due a tendency to decompose---and even lose the property of electrical inertness inherent to these products---under such variables as ambient temperature & other environmental conditions, and the user should exercise caution in both the amount of compound used and the areas with which it is allowed to contact. The user should be aware that the properties of thermal greases will degrade over time and require re-application of a new layer; old, broken-down heat sink compound should always be thoroughly removed first by cleaning both surfaces with alcohol or an adequate solvent (carefully-applied acetone---often available amongst everyday household products in the form of fingernail-polish remover---is a favorite product of choice for many experienced technicians
What is a processor clock speed?
Here is a short explanation.
Clock rate or clock speed is the speed at which a microprocessor (CPU) executes instructions. Clock speeds are typically expressed in megahertz (MHz) or gigahertz ((GHz). A single clock cycle (usually shorter than a nanosecond in modern non-embedded microprocessors) toggles between a logical zero and a logical one state.

1156 - for coewi3 nad core i5
1366 - for flagship i7
there are others for the xeon server chips (i think) but that's business and enterprise not consumer
What is better an Intel Pentium III or an Intel Celeron?
Celeron doesn't refer to any particular processor series. Celerons were cost-reduced versions of their Pentium equivalents. The Celeron in question could be based on a Pentium 2, Pentium 3, Pentium 4, Pentium D, or Core 2 Duo. In which case the answers would be "Pentium 3, Usually Pentium 3, Celeron, Celeron, and Celeron", respectively.
Ability to perform certain logic operation?
The Logical operator has the ability to perform certain logic operations on its input. This is used in Boolean algebra.
When the microprocessor receives an Interrupt Service Request (ISR) on the interrupt line it must determine which of the devices connected to that input sent the request.
Software Polling is one method by which it can do so.
In Software Polling:
A software routine is used to identify the device requesting service. It does so by checking each device to see if it was the one needing service.
Difference between direct addressing mode and indirect addressing mode in detail?
Direct addressing mode means the operand address is contained in the instruction. In the 8085, an example is LDA 1234H, which loads the accumulator with the contents of memory location 1234H. In the 8086/8088, an example is MOV AL,[1234H], which accomplishes nearly the same thing.
Indirect addressing mode means the operand address is contained in a register. In the 8085, an example is LDAX B, which loads the accumulator with the contents of the memory location specified in register BC. In the 8086/8088, an example is MOV AL,[BX], which accomplishes nearly the same thing.
