The Instruction set refers to the commands that a CPU knows how to complete?
Yes, Instruction Set is the list of OPCODES that CPU (Processor) understands & performs on those instructions (i.e. enables devices to communicate, process received instructions & directing towards the right output devices).

The microprocessor control unit of a modern washing machine is not a microcomputer why is this?
Because the microprocessor of a washing machine is a dedicated computer while a microcomputer is general computer that performs a variety of tasks.
What is the vhdl code for 8253 microprocessor?
VHDL code for 8253 need to be written in structural modeling of VHDL. It will be a bunch of programs related to each and every component or functionality we use in 8253 and need to be combined. It is not a single program. It is a combination of several programs.
The Intel Itaniums use a new instruction set called?
The instruction set is usually called IA-64. This is not to be confused with EM64T, a 64-bit instruction set used in mainstream desktop processors. The answer your looking for is (EPIC)Explicitly Parallel Instruction Computing Chicagocubano strikes again
Who makes the CPU for the emachines?
Well it varies from lots of different categories. To a gaming machine and a regular PC. but according to me mine was made by ASROCK motherboards incorporated. Does that answer your question? If it doesn't contact me for any other questions about PC's. John-Waldron@hotmail.com
What are the different brands of CPU?
The two major brands of personal computer CPUs are AMD and Intel. A distant second runner up is Via, which makes CPUs for netbooks and other low-power applications. These all manufacture CPUs using the x86 and x86-64 instruction set.
Why the twisted pair cable gets heated while transferring the data in a LAN?
Data travels through cable in the same way that electricity travels through wires. There is a very small amount of power used and the cable, although made of highly conductive material, has some resistance. This resistance causes heating. This heating would not normally be noticable, even under conditions of very high data transfer. If you are noticing a significant amount of heating, it's possible that electricity is finding it's way into the cable from another source.
Are you using PoE (power over ethernet) devices on this Cat5 cabling ? If several of these cables are using PoE and are bound together tightly there may be an increase in temperature. Do not use ty wraps, use velcro instead, and don't bind them too tightly.
What is the size of the instruction queue in 8086?
In 8086 the instruction queue is 6 byte long. This is because even the longest 8086 instruction is 6 byte long. Thus it is possible to prefetch even the longest instruction in the instruction set.
What are the function and duties of a computer microprocessor?
The main function of this part of the computer is to read scripts and process computer programs.
Why was the first Intel Celeron processor not as popular as expected?
The original Intel Celeron processor was not as popular as expected because it lacked the level 2 cache to help reduce the price of the processor. With no level 2 cache, the processor acted much slower than the competitor processors.
What is the main difference between RISC and CISC in computer architecture?
Reduced Instruction Set Computer (RISC) vs. Complex Instruction Set Computer (CISC).
(1) CISC computers typically require more than one clock cycle to execute a given instruction
(2) RISC computers typically require only one clock cycle to execute a given instruction
That said, a CISC "opcode" can often perform more than a RISC "opcode". This results in much shorter code for CISC machines which is much easier to read and maintain. That said, CISC computers often have "dead cycles" in which the processor isn't doing anything useful, or is performing a redundant command.
As an example, if one tries to do a MULT memoryLoc1, memoryLoc2, register followed by an ADD memoryLoc1, memoryLoc2, anotherRegister, then a CISC machine must access main memory (or cache) 4 times and perform 2 computations and two moves from the ALU to a register. A RISC machine (while requiring more, but simpler, instructions) would never need to go out to memory for the additional 2 times since the information was already retrieved. Memory access can be a very time expensive operation.
All in all, RISC code is much more optimize-able and significant performance improvements can be realized over CISC.
What type of memory is fastest and used for the CPU cache?
SRAM or Static RAM is the fastest, and most expensive type of RAM available in computers. it is used in the L1, L2, L3, and L4 cache on your processor and chip-set (or however many L-caches your system has). it is the fastest type of RAM because it does not have to be refreshed as frequently as DRAM.
no of registers of each window = l + g + 2c... where l = local register, g = global registers, c = registers which are common
no of registers in processor are (l + c)w + g... w = no of registers in windows

What is the difference between a Solid-state Drive and a computer processor?
one is a hard drive and one is the cpu.......ssd=storage.......processor(cpu)=crunches the data.....
Can a bad power supply cause a CPU to overheat?
Yes, if your fan stops working because your power supply went bad, the CPU could overheat very easily and shut down or even crash resulting in loss of data.
Why is the processor required?
A processor is the thinking mechanism of the computer. While a Hard Drive/Disk holds the data of a computer, the processor is what 'thinks' and determines how to run whatever files are on your computer, as well as keeps them updated. Basically, if you have no processor, your computer will sit with a load of data and take no commands, do no thinking or display information. in simpler words it is the heart of the mahine without it you can't do anything.
What is the difference between P and T processor?
The T-series has a "Thermal Design Power" (TDP) of 35W, while the P-series has a TDP of 25W. TDP represents a maximum amount of cooling that a computer manufacturer must design the laptop's cooling system to dissipate X amount of heat. Therefore, a laptop with P-series of processor can - in theory - be designed to dissipate 10 less watt. What does that mean to the end user? The manufacturer can use a smaller, quieter fan/heatsink, yet the laptop's CPU can still operate within specification. I want to emphasis "in theory" is because Intel defines that TDP as "The maximum amount of heat which ...processor will operate under normal operating conditions." Which means at the CPU is running at 100% constantly, the CPU will likely output an amount of heat higher than TDP. So the computer manufacturers may not want to cheapen out their heatsinks/fans even if they are using a "P" rather than a "T". (On the other hand, AMD defines TDP to be the maximum power a CPU will draw [under standard clock rate, of course], so for an AMD CPU, it won't draw any higher than the listed TDP at the rated clock. )
its a technology which reduces noise and heat and increases energy efficiency

What is the advantages of multicore processor over single core processor?
Hyperthreading is cheaper, and will produce less heat. Overall though, dual-cores are better.
