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.

Differences between microprocessor and microcontroller?
It's really a question of symantics. "Microprocessor" typically refers to a PC-style CPU, that is, an adaptable piece of silicon that can be instructed to perform most forms of tasks. "Microcontroller" typically means a CPU that is solely dedicated to one purpose.
In other words, a PC would have a microprocessor, while a microwave would have a microcontroller.
What should the technician use to clean the heat sinks?
The cleaning of heat pipes and sinks can be done with two different chemicals (among others). Highly purified Isopropyl alcohol and chemist grade acetone are two examples. That being said if the heat sinks and pipes are made of copper do not expose them to ammonia which can react.
Is there anyway to improve a computer processor speed without buying a new processor?
Usually, a computer is sold with the minimum amount of Random Access Memory installed for the computer to work properly. Increasing the amount of memory will usually result in much faster processing. If that is not sufficient, it may be possible to overclock the processor, but that is extremely dangerous, and can result in the processor burning up. Do not attempt this without skilled assistance.
logical cache is what computer companies call L1, L2, and L3 cache.
It is smart memory on the chip or processor that remembers what the processor has ask for the last 10 to 100 processes.
CPU - Central Processing Unit - is commonly mentioned in Computer Science books of Tamilnadu Govt. as "Maiya Kattuppaattu Seyalaham" (மைய கட்டுப்பாட்டு செயலகம்).
How many bits does WEP encryption use to scramble data packets?
the answer is 40 bits the other person oviously dident realize the difference between computer type and WEP encryption any enjoy the answer
Why Bicmos technology is not used in microprocessors?
Using BJT technology alone would not make a viable microprocessor, as power consumption and heat dissapation would become problematic. Mixed technology BiCMOS complicates the manufacturing process, increasing the shelf cost of the end product.
The six components of a computer are CPU input devices output devices communication devices storage?
I think that today's computers really have more than six components, although I guess this depends upon whether you are - in taxonomical language - a lumper or a splitter. For a start, I would not ignore the various data buses which create the connectivity between processor(s) and the memory chips, RAID arrays of SCISI/SATA drives, and lots of USB plugin sockets. Also, you will not get very far on your PC without an assortment of I/O devices to manage your mouse and keyboard and either a plugin or on-M/B graphics generator so you can see what you are doing (on the monitor or TV, depending), not to mention today's invaluable ethernet device so you can LAN and WAN and route away to your heart's content. Finally, do not forget the multi-voltage DC power supply, without which none of the aboce will even warm up let alone "glow" for you. I agree that simple is nice, and classification is always a boon to clearer understanding, but I don't think that your six components quite cover the ground, so to speak. Others may disagree, as is the way of the world!
What are the disadvantages of a microkernel?
suffer from performance decreases due
to increased system function overhead. Consider the history of Windows NT.
The first release had a layered microkernel organization. However, this version
delivered low performance compared with that of Windows 95. Windows NT
4.0 partially redressed the performance problem by moving layers from user
space to kernel space and integrating them more closely. By the time Windows
XP was designed, its architecture was more monolithic than microkernel.
Outline steps in CPU writing to memory?
1 The processor puts the required addresses on to the address bus
2 Any addresses that invoke chip select are decoded
3 Chip select is generated
4 The processor waits for memory to settle
5 The processor generates a memory write control bit (MEMW)
6 The processor puts the data on to the data bus
7 The contents are written to a specific location on memory.
PC CPU overheat temperature check?
Just shut your computer down for a few minutes and let it cool down, or not run a lot of programs at a time...
How do you use 8 bit register as 16 bit register?
8 bit registers cannot be used as 16 bit registers. The reverse works, however, as the 16 bit general purpose registers of the 8086 and 8088 can be used as pairs of 8 bit registers. AX is divided into AH (high 8 bits) and AL (low 8 bits), and BX, CX, and DX are similarly divided.
Operations on 16 bit and operations on 8 bit registers are similar. So you can do add ah, bl, just as you could do add ax, bx.
What is READ pin in 8085 in microprocessor?
The read pin (RD/) on the 8085 is pin 32. It indicates that external logic should drive the data bus with data during a read cycle. It goes true (low) one half clock cycle after the falling edge of ALE, at which point external hardware should have strobed the content of the data bus to record the low order address bus value. At the same time, READY (pin 35) is sampled. If READY is found to be false (low), the processor holds the state of all lines for one clock cycle and then repeats. One clock cycle after READY is true, the processor samples the data bus. One half clock cycle later, RD/ is set false (high), ending the read cycle, at which point the external hardware must stop driving the data bus. One half clock cycle later, a new machine cycle starts with the rising edge of ALE.
Can you upgrade the CPU or processor in the hp pavilion d1mz Laptop?
unlikely most laptops CPU are soldered to the board either get a new one or send it back for an upgrade
How can you adjust your computers CPU?
You can adjust a great number of things with a CPU. Core frequency, link / bridge / bus frequency, and voltage are just a few things you can change.
How do you solve when CPU is beeping?
How much, when, how long, when you are doing what? Please be more specific.
The advantages of downloading the main program into a microprocessor based system can be it can cause the system to run efficiently and the main program will be able to be easily accessed through the microprocessor system. Disadvantages can be due to errors they can happen due to system failure.
Is a 2.0 GHz P4 processor just as good as a 1.8 GHz processor?
If the amount of cores it has is the same 2.0 is better.
Additional: The above is 100% wrong. A 600Mhz single-core high IPC high bus-width old server processor will outperform a 2.0GHz P4 in all and any tests on the planet.
If the 1.8GHz processor isn't an incredibly poorly designed P4, then it is probably actually better than the P4. It takes a very, very high clock frequency to make a P4 contend with anything in today's world.
What is the difference between a computer with core duo to a computer without core duo?
Basically, core duo, is 2 CPU's running at the same time. Although there is still only the one in the PC. It allows you to multi-task far more easily, than a CPU on a single core.
Ie you could burn a DVD, watch a movie, and surf all at the same, time, with no real degredation to your performance.
Upgrade processor dell gx 280?
I was looking for the answer to this for myself and after scanning through Dell's forums it would seam that the Optiplex GX280 will support Pentium IV 5xx and 6xx CPUs. There are reports of people successfully using Pentium IV 640 and 650 processors. (3.2/3.4GHz, 800MHz FSB, 2MB Cache, 65nm "Cedermill") It seams they will not support any dual core CPUs, e.g. Pentium IV 8xx, 9xx or "Core" series.
GX280 SFF small form factor computer support 3.2/3.4 CPU on my computer....
What range do processor speeds achieve?
The processor speed depends on the specific processor. In general, most processors have a range of about 1 gigahertz on the lower end to about 3.6 gigahertz on the upper end.
