A Pentium 4 contains 42 million transistors. Forty-two million transistors isn't very many--the highest-end Itaniums and Xeons have nearly two BILLION transistors.
What is multithreading microprocessor?
If this is a homework assignment, please consider trying to answer it yourself first, otherwise the value of the reinforcement of the lesson offered by the assignment will be lost on you.
Multithreading is an operating system concept, not a microprocessor concept. Multithreading allows you to create a process with more than one concurrent execution path. This gives the impression, or the reality, of being able to do more than one thing at a time.
Microprocessors with multiple cores enhance multithreading, by allowing the operating system to dispatch more than one thread simultaneously, as opposed to concurrently.
89S52 has ISP
so S stands for : Serial in System programmable.
WHAT part of the processor is responsible for directing actions performed by the processor?
When an instruction reaches a microprocessor it arrives at an internal block known as a "microcode sequencer" which is present in CISC architectures. This microcode sequencer then steps through a series of locations in the microcode ROM and issues control signals to the various registers, multiplexers, ALU, etc in the microprocessor.
RISC architectures lack this microcode sequencer, but have a similar construct known as a microcode translator or interpreter. Because RISC machines must complete execution in a single clock cycle, there aren't any "steps" to cycle through. Remember that RISC instructions are inherently more simple than CISC instructions.
the six are CPU, memory, power supply, input devices, output devices, & storage devices
These are notes my teacher gave to me-
1. INPUT- sends data to the main memory
2. PROCESSOR- processes or manipulates data into information. This is done through the CPU- Central Processing Unit- this is made up of the control unit & arithmetic/logic unit.
3. MEMORY- electronic components that temporarily store instructions waiting to be executed by the processor.
4. OUTPUT- displays or present information- is made up of printers & display panels.
5. STORAGE- stores the information for future use when not being used in the memory.
6. COMMUNICATION DEVICES- a hardware component that enables a computer to send (transmit) & receive data, instructions, & information to & from one or more computers. ex: telephone lines, cables, cellular radio networks, & satellites. Some media is wireless- no physical lines or wires needed.
• What is the maximum directly addressable memory capacity (in bytes)? 2(32-8) = 16,777,216 bytes = 16 MB • Discuss the impact on the system speed if the microprocessor data bus has • a 32-bit local address bus and a 16-bit local data bus. Instruction and data transfers would take three bus cycles each - one for the address and two for the data. • a 16-bit local address bus and a 16-bit local data bus. Instruction and data transfers would take four bus cycles each - two for the address and two for the data. • How many bits are needed for the program counter and the instruction register? 24 bits for the PC (24-bit addresses), 32 bits for the IR (32-bit addresses)
inter integrated circuits its a master protocol and uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock (SCL), pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems with other voltages are permitted

Why we use computer why computer is usefull what are the benefits of computer?
They operate with amazing speed, reliability, consistency, and accuracy
Spellcheck is great too. Ahem.
Hmmm... another homework question. It never ceases to amaze me how many kids don't want to do their homework so they just ask the questions here.
Depends on the benchmark used to measure:
- KOPS or KIPS - measure of instructions executed per second
- MFLOPS - measure of floating point operations per second
- Whetstones - measure of overall floating point performance
- Drystones - measure of overall integer performance.
- Livermore loops - measure of computing and looping performance
- etc. etc.
Never measure CPU speed by the clock speed. Different architectures and implementations of the same architecture can give dramatically different speeds on real applications even with the CPUs running on the same clock.
One example of this occurred when Apple first started making Macs using the PowerPC. Power Macs could run in software emulation of the Intel Pentium Windows applications much faster than the existing PCs, even though the PCs operated on faster clock speeds and were running the code native.
Which memory module has a front side bus speed of 200 MHz?
If you are referring to standard RAM modules for a computer I believe you're looking for "PC1600" DDR ram. Not DDR2 or 3, just plain DDR ram.
Hope this helps!
What is the difference between Branch Save address Branch unconditional?
Branch Save Address saves the current program counter, usually in the first memory location of the subroutine that you are branching to so that the main routine can be later resumed at the exact spot that you branched from.
Branch unconditional on the other hand does not save the program counter, and therefore provides no way to return to your previous location.
What is the difference between 2.66 dual core and 64bit dual core?
The difference between 2.66 dual core processor, and 64-bit dual core processor, is really two different processor specifications. 2.66 is actually 2.66Ghz, which is the clock speed of the processor. The clock speed tells you how many times the processor can execute instructions per second. A dual core processor is a processor with two cores on one die. This can be thought of as having two processors in one. The bit specification of a processor tells you how many binary instructions a processor can execute per clock cycle. Most processors today are 32-bit (32 binary instructions per clock cycle) or 64-bit (64 binary instructions per clock cycle). More RAM can be used with a 64-bit processor. A 32-bit processor is limited to addressing 4 Gigabytes of RAM, while a 64-bit process can address (theoretically) 16 Exabytes of RAM.
Which uses more power a desktop or laptop of the same processor speed?
The desktop would, I would think, as it is bigger and has more space for that kind of power.
This is correct but not for that reason (desktops are mostly empty space). Laptops are designed to use low power and be portable so they uses more expensive parts that use less power.
What allows the processor to communicate with peripherals?
The key for any hardware piece to work with others is the SOFTWARE. That is why anything you buy for your computer (graphics cards, hard drives, etc.) it comes with software (or the driver) to help the computer recognize it and use it for the function its meant to be used for. I hope this is what you were looking for.
What is an explanation of in brief microcomputer?
A microcomputer is a complete computer on a smaller scale and is generally a synonym for the more common term, personal computer or PC , a computer designed for an individual. A microcomputer contains a microprocessor (a central processing unit on a microchip ), memory in the form of read-only memory and random access memory , I/O ports and a bus or system of interconnecting wires, housed in a unit that is usually called a motherboard .

In an ascending hierarchy of general computer sizes, we find:
- An embedded systems programming computer, which is embedded in something and doesn't support direct human interaction but nevertheless meets all the other criteria of a microcomputer
- Microcomputer
- workstation , as used to mean a more powerful personal computer for special applications
- minicomputer , now restyled a "mid-range server"
- mainframe or mainframe computer, which is now usually referred to by its manufacturers as a "large server"
- Supercomputer, formerly almost a synonym for "Cray supercomputer" but now meaning a very large server and sometimes including a system of computers using parallel processing
- A parallel processing system is a system of interconnected computers that work on the same application together, sharing tasks that can be performed concurrently
What is the need of microprocessor in electronics?
because with the help of microprocessors we need not to solve large no. of equations every rime as we do with gates..
How do you find out what kind of CPU you have ie make and speed?
