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.

In computer networks, failover support is a method for protecting availability of a computer resource. For failover support to work, a component must have a redundant or alternate and there must be an ability to detect the failure of the primary component and switch to the alternate. As an example, a company web site may be hosted at one location but have an alternate hosted at a different location. If the primary site goes down, traffic directed to the primary site is redirected to the alternate site in a manner that is transparent to the outside user.
The functions of an interface is to connect two different items together and make them work. The most common interfaces are Parallel, Serial, USB, Infrared and PS/2.

For a stable processor, usually the boutiques advertise around 4.0 to 5.0GHz, usually a Extreme Intel chip or at least an E8400-8500 Core2Duo which is well know to hit 4.0GHz using the factory Intel heatsink without problems in most cases.
Why would a computer's processing speed fluctuate from 1.99 GHz to 256 MHz Randomly?
Many processors are designed to automatically reduce their speed when not in use in order to conserve power.
Will a faster CPU make startup programs load faster?
A faster CPU will speed startup ONLY if you have enough RAM; adding RAM is generally a cheaper speed upgrade if your motherboard & OS can support it.
You should also make sure all your start up programs and device drivers are up to date, as newer programs and drivers are often faster.
Does the Intel Core i3-3220 3.3GHz Dual-Core Processor CPU have an inbuilt graphics card?
Yes, the Intel Core i3 3220 3,3 GHZ does have an inbuilt graphics card and namely the Intel HD 2500 graphics version.
If you have its ip address you could give it to the police and track it but if its in your own home u might have trouble since it will only indicate the house its in
Which registers are changed by the cmp instruction?
MP Compares the first source operand with the second source operand and sets the status flags in the EFLAGS register according to the results. The comparison is performed by subtracting the second operand from the first operand and then setting the status flags in the same manner as the SUB instruction. When an immediate value is used as an operand, it is sign-extended to the length of the first operand.
So, only the flags are affected.
Operation:
temp = Source1 - SignExtend(Source2);
ModifyStatusFlags(); //Modify status flags in the same manner as the SUB instruction
Flags affected:
The CF, OF, SF, ZF, AF, and PF flags are set according to the result.
CPU is neither an input device nor an output device. It is the central processing unit. Unit which takes inputs from input devices like keyboard, mouse, sound input etc. does the processing as per the application running on the machine and gives an output to output devices like screen display, a printer or sound output.
I'm not sure What you mean exactly ? Another name for the Microprocessor? That is known as (CPU) Which is the heart of a Computer. Which Controls Logic, and Control Operations, Reads, Writes, Executes Bits Bytes Data, and is the Primary Control for Processing Data (Centeral Processing Unit) MicroProcessor,''Single circuit Chip''
Your Pentium d processor speed is 2.8 Ghz does that mean you have 2 cores each of 1.4 ghz?
No. Each core runs at 2.8 GHz. Threads can be run on each of the processors at the same time, drastically improving performance in certain situations. It does not mean that the computer is linearly twice as fast though.
A personal area network or PAN consists of personal devices at close range such as a cell phone, PDA, and notebook computer in communication. This computer network is used to transmit data among devices.
Does a printer have a processor of its own?
Yes it does. This processor is used to render the image that is to be printed. This is why the computer must only send text with some formatting data to the printer instead of a rendered image, which would require much more bandwidth.
Does a msi G31tm p21 LGA 775 Intel g31 micro atx Intel motherboard have a CPU built in?
Modern PC motherboards do not typically come with a CPU "built-in." You have not provided enough information to determine whether or not the vendor you are purchasing the board from may be bundling a processor with it.
What is the difference between Mac OS X PowerPC and Mac OS X Universal?
In reference to installation CDs or binaries, Universal refers to its ability to run on both PowerPC and Intel-based Macs. PowerPC binaries can only be run on Intel Macs via emulation, which can be quite slow.
F Explain the concept of 2 way set associative Cache memory with the help of an example?
Which memory locations can be cached by which cache locations
The replacement policy decides where in the cache a copy of a particular entry of main memory will go. If the replacement policy is free to choose any entry in the cache to hold the copy, the cache is called fully associative. At the other extreme, if each entry in main memory can go in just one place in the cache, the cache is direct mapped. Many caches implement a compromise in which each entry in main memory can go to any one of N places in the cache, and are described as N-way set associative. For example, the level-1 data cache in an AMD Athlon is 2-way set associative, which means that any particular location in main memory can be cached in either of 2 locations in the level-1 data cache. Associativity is a trade-off. If there are ten places the replacement policy can put a new cache entry, then when the cache is checked for a hit, all ten places must be searched. Checking more places takes more power, chip area, and potentially time. On the other hand, caches with more associativity suffer fewer misses (see conflict misses, below), so that the CPU spends less time servicing those misses. The rule of thumb is that doubling the associativity, from direct mapped to 2-way, or from 2-way to 4-way, has about the same effect on hit rate as doubling the cache size. Associativity increases beyond 4-way have much less effect on the hit rate, and are generally done for other reasons (see virtual aliasing, below). In order of increasing (worse) hit times and decreasing (better) miss rates, * direct mapped cache -- the best (fastest) hit times, and so the best tradeoff for "large" caches * 2-way set associative cache * 2-way skewed associative cache -- "the best tradeoff for .... caches whose sizes are in the range 4K-8K bytes" -- André Seznec[3] * 4-way set associative cache * fully associative cache -- the best (lowest) miss rates, and so the best tradeoff when the miss penalty is very high
Give you 5 examples of microprocessors?
This term stands for a general purpose digital computer consisting of the CPU (Central Processing Unit). A microprocessor usually contains an ALU (Arithmetic Logical Unit.
In the CPU , majority of the operations and tasks assigned to the microprocessor are completed. In the ALU , only arithmetic ( addition , subtraction etc.) and logical ( And, Or , Not etc.) are taken care of.
The prime use of a microprocessor is to read data, perform extensive calculations on that data and store those calculations in a mass storage device or display the results for human eye. This sits on the motherboard of each PC ( Personal Computer). The motherboard stands for the card in the PC that controls almost all the other peripherals. Examples of microprocessors are the Intel 8085 ( one of the first microprocessors), P1 family, P2 and now the P3 family from Intel Inc.
Is sending an Email a function of the CPU?
No. It is a function of an application (SMTP is an e-mail sending protocol within these applications).
