Microprocessors
A microprocessor is the heart of any computer, whether it is a server, a desktop machine, or a laptop. This single chip contains the arithmetic, control, and logic circuitry necessary to interpret and execute computer programs.

What is an alternative for a CPU?
There is no alternative for a CPU - Central Processing Unit. It's the brains of the computer. Without it, there's no control point on the motherboard.
What is the difference between microprocessors and CPUs?
Another Answer
The CPU (Central Processing Unit) is the core of any computer, while the microprocessor refers to the whole functional chip that is inserted into a motherboard. The CPU is the sub architecture of the microprocessor that interprets the program instructions and cascade triggers the sub-functions of each instruction.
Are Intel microprocessors compatible with windows 7 eg Intel R Pentium R M processor 1.73GHz?
It would run Windows 7 just fine as long as you have more than 1GB or RAM
Set up of multiple monitor in one CPU?
If you have multiple monitor ports the set up is easy, just plug in the other one. Without alternate ports you would probably need to have some sort of splitter set up for the monitor port or find another connection for the monitor, like USB.
What is machine cycle and the steps to draw timing diagram?
A machine cycle is three or more T cycles used to perform a memory / IO read or write, or an interrupt acknowedge
- Draw a square clock oscillator waveform of at least 3 cycles, more if you want to show READY timing.
- Each T cycle starts at the falling edge of clock, with the first T cycle starting with ALE.
- Draw an ALE pulse, one half clock cycle, inverted and slightly delayed from clock.
- Approximately 1/3 into ALE, draw the IO/M-, S0, S1, and A8-A15 lines becoming valid. They stay valid for the duration of the cycle.
- Approximately 1/3 into ALE, draw the AD0-AD7 lines becoming valid as A0-A7. Note that external logic must strobe these lines on the falling edge of ALE. The AD0-AD7 lines remain valid for about 1 clock cycle.
- On the second T cycle, draw the RD-, WR-, or INTA- lines becoming valid. The determination is known in advance if one looks at IO/M-, S0, and S1. They are valid for 1.5 clock cycles, except see READY logic below.
- Show the READY line being sampled in the rising edge of clock after ALE falls. If READY is false at that point, T2 will be repeated until READY is sampled true.
- As noted AD0-AD7 float 1/2 clock cycle after ALE. 1/2 clock cycle later, they become D0-D7, and drive for WR- or stay floating for RD- or INTA-.
- External logic is expected to strobe D0-D7 data at the rising edge of WR-. D0-D7 will remain valid for 1/2 clock beyond WR-.
- External logic is expected to drive D0-D7 during RD- or INTA-. The processor will strobe D0-D7 1/2 clock cycle before the rising edge of RD- or INTA-.
- Note: Address to read data valid timing is 2 clock cycles, and address to write data valid timing is 2.5 clock cycles. The difference is due to who controls the AD0-AD7 bus, and when it gets strobed.
- 1/2 clock cycle after RD-, WR-, or INTA-, at the rising edge of clock, the machine cycle ends. Depending on whether or not internal processing must be done, ALE may or may not be emitted, starting another machine cycle.
- HOLD is sampled on the falling edge of clock in the third T cycle. If recognized, HLDA is asserted 1/2 clock cycle later, 1/2 clock cycle later, the whole control bus floats so another bus master can take over.
What hardware component of a computer should you upgrade to increase its CPU capacity?
the answer to that one is prob. in your textbook
How do you determine if CPU or GPU separated from the PS3 motherboard?
You will get the Yellow Light of Death. Usually the best way to tell if the RSX is separated from the board is when you turn on your PS3 the machine will make a "humm" noise as it shuts down to the red blinking light. If it YLODS without the humming noise then it is definitely a bad power supply but 90% of the time a YLOD is caused by the RSX separated from the board.
Which Microsoft operating system support 16-bit device drivers or 32-bit device drivers?
Windows 95 & Windows 98
What was the platform of the AMD K6 MMX processor?
That would go on a socket-7 motherboard. Socket-7 is the same platform as what was used for the original Pentium processor. That was out around the time that Windows 95 and Windows 98 were popular.
A microprocessor is the main part of a computer. It is the engine of a computer that has been created on only one chip. It stores data, moves data from one memory location to another, communicates with other parts of the computer, can do computations, and is controlled by assembly language instructions, that it fetches from some memory.
How many processors does the 80486 CPU have?
It was only when Intel developed the Core Duo that they had more than one core or processor per chip
IMPROVED:
The 486 CPU was the first CPU Intel made which utilized a single processor chip for all functions. Before it, processors such as the 286 and 386 utilized two processors (an ALU and a math coprocessor) to perform tasks, as they could not fit both functions onto one.
Now, all processors have a built-in ALU and math-coprocessor. As of the Intel Core Duo they contained two separate cores in a single processor. It is still, however, a single processor! It just has two cores and thus can function as two separate CPUs. This trend continued in the Core 2 Duo line.
How does the operating system share the CPU in a multitasking system?
There are two basic ways of establishing a multitasking environment; timeslice and priority based.
In a a timeslice multitasking environment each application is given a set amount of time (250 milliseconds, 100 milliseconds, etc) to run then the scheduler turns over execution to some other process. In such an environment each READY application takes turns, allowing them to effectively share the CPU.
In a priority based environment each application is assigned a priority and the process with the highest priority will be allowed to execute as long as it is "ready", meaning that it will run until it needs to wait for some kind of resource such as operator input, disk access or communication. Once a higher priority process is no longer "ready", the next higher process will begin execution until it is no longer "ready" or until the higher priority process takes the processor back.
Most real-time operating systems in use today tend to be some kind of combination of the two.
What is the chip that wakes up the computer?
See the Intel reference specifically regarding WAIT states.
The 16 bit microprocessor means that it has?
8 bit ALU and most of data processing registers will be 8 bit
currently they are all made of electronic components. some used to be made of magnetic components. in the 1960s there was some work on making them of miniaturized hydraulic (fluidics) components because they would not be sensitive to radiation from nuclear bomb blasts. in the early 1940s some were mechanical. just about any technology can be used.
Arithmetic Average Roughness Height. It's unit is in microns.

mov r1r2 is invalid instruction because of there is no communication with ALU in its operation;
