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.

Why do you need to keep your computer plugged when replacing a CPU?
You don't. Actually it is imperative that you UNPLUG your computer before trying to change your CPU. In addition, you need to make certain that you are grounded before you attempt to replace the CPU to avoid static discharge.
Continuing on this from Original poster:
I have been told by guides and other sources that you do keep the computer plugged in.
How compare instruction is used in 8085?
The compare and subtract instructions in the 8085 both subtract one operand from another, and set flags accordingly. The subtract instruction stores the result in the accumulator, while the compare instruction does not - except for the flags, the compare instruction "throws" the result away.
This is the the thing for micro controller . Normally in microcontroller operation we used to give the clock pulse to connected circut chips .One chip requires 4 clock pulse .then the second, third vise versa . By which the pulse starts from 4 is for first chip, 8 is for second chip(4+4), 16(4+8+4) is for thir.............Like that depending upon the requirement of the clock signal for chips we used to tell 16 bit counter , 32 bit counter ect.
There are 1024 kilobytes in a megabyte. Assuming you aren't worried about being exact just divide by 1000.
So you are looking at around 56 MB.
There are actually 2 answers to this question.
In the decimal system (often used in networking and storage such as HDD) 1 MB = 1000KB. So 1,000,000 KB = 1,000 MB = 1 GB.
In the binary system (mostly used in RAM memory) 1MB = 1024 MB. So 1,000,000 = 976.5625 MB = 0.95367431640625 GB
Answer you are looking for: 1000000 kilobyte = 976.5625 megabyte
What is the difference between a multichip microcomputer and single chip microcomputer?
the IC that is organized as a single-chip microprocessor contains only CPU without the other peripherals like ROM, RAM, and I/O ports that comprise a microcomputer, while the single-chip microcomputer is the chip that contains all the components that give the capabilities of the microcomputer.
What is the basic construction of microprocessor?
1)address lines to refer to the address of a block
2)data lines for data transfer
3)IC chips 4 processing data
A control unit in general is a central (or sometimes distributed but clearly distinguishable) part of whatsoever machinery that controls its operation, provided that a piece of machinery is complex and organized enough to contain any such unit. ...All steering devices with connections to the parent device and which can steer, direct, or change its operational parameters. This can be done by automatic, semi-automatic or manually operated commands.

How do you perform multiplication of two numbers without using the multiplication operator?
By using repeated addition. Consider two numbers a and b. If you want to find a*b then you can add the numbers repeatedly in a loop to get the product. Eg:
product = a;
for( i=1; i<=b; i++)
product+= a;
What are the Modern usage of microprocessor?
Microprocessor is nothing but the Integrated Circuits (ICs), are found in many applications from household - Microwave Ovens, Refrigerators etc. to time critical and the mission critical applications such as Nuclear Power Reactors, Aerospace vehicles and even could found in our digital computers.
Microprocessor's components include the storage devices such as the registers, the devices to perform the arithmetic and logic operations and control devices which control the flow of information through the Microprocessor.

Is it possible to upgrade a processor without reinstalling the OS?
1) you can install a new processor if a) your motherboard will support it b) it is the right type of socket or slot
2)you do not need to re-install anything for a new processor.. the only time you need to re-install is when changing hard drives
3)a faster CPU may help, depending on to what type it is, and sometimes more ram does the trick also..
Yes, it may give you a message when you boot into Windows after the installation of the new hardware saying, "Change in Hardware, please reactivate Windows," and all you have to do is give Microsoft a call and they'll activate it for you.
CISC stands for Complex Instruction Set Computer. CISC chips are relatively slow per instruction,but use little instructions RISC stands for Reduced Instruction Set Computer. A fewer, simpler and faster instructions would be better, than the large, complex and slower CISC instructions. However, more instructions are needed to accomplish a task. It's easier to write powerful optimised compilers, since fewer instructions exist.
Discuss the concept and importance of semaphores?
n programming, especially in Unix systems, semaphores are a technique for coordinating or synchronizing activities in which multiple processes compete for the same operating system resources. A semaphore is a value in a designated place in operating system (or kernel) storage that each process can check and then change. Depending on the value that is found, the process can use the resource or will find that it is already in use and must wait for some period before trying again. Semaphores can be binary (0 or 1) or can have additional values. Typically, a process using semaphores checks the value and then, if it using the resource, changes the value to reflect this so that subsequent semaphore users will know to wait.
Semaphores are commonly use for two purposes: to share a common memory space and to share access to files. Semaphores are one of the techniques for inter-process communication (IPC). The C programming language provides a set of interfaces or "functions" for managing semaphores.
In a byte MSB is the bit that represents value 2^7, LSB is the bit that represents value 2^0.
What processors are used with Socket AM3 Connector?
The Socket AM3 Connector is compatible with the AM3 and AM3+ processors, but not AM2 or AM2+ processors, which have 940 pins instead of the 941 pins of the AM3/AM3+.
