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 the difference between CPLD and microcontroller?
Complex programmable logic device (CPLD) are programmable digital logic devices which are simpler and lesser capacity than FPGA (Field Programmable Gate Arrays) devices. CPLDs have a non-volatile memory (i.e. turning off the power does not require reprogramming of CPLD)
Microcontrollers (uP or MCU) are small and cost effective but self contained computer chips (compared to general purpose processor chips used in personal computers) used for embedded applications in industrial, consumer electronics products and automobiles. Microcontrollers may or may not have inbuilt memory.
CPLDs are used for implementing logic but they do not have a embedded processor like in microcontrollers.

All micro-controllers are going to be difficult to use, because you build your circuits around them, not vice versa. From a programmer perspective, the BASIC Stamp uses PBasic which is very easy to use and understand. The PIC16F84 Micro series uses assembly, but only has 30 commands and is much more powerful IMHO.
Bit addressable registers in 8051?
just a note: Clarify your question
Bit-addressable registers are registers that its bits can be modified individually. that means if you have register named "ACC" that is bit addressable , you can change its bits (D0 -D7) individually by special instructions SETB and CLR.
ex: SETB ACC.3 ; will set bit number 4 (remember bit 0) in the register
in 8051 there are many bit-addressable registers such as A (ACC), B, SCON, PCON, TCON, p0,p1,p2,p3 .
best wishes,

Where can one find best processors?
There are a lot of great sites that give great electronic deals. Definitely check out Amazon and their Deals of the Day. You may also want to check out, Brandsmart USA, Best Buy, Newegg, and Microcenter.
How long does it take to load 15 MB at 40 kb a second?
6m 24s
You Have 1024 Kb's In A Mb. So Take 1024 x 15, Since The File Is 15 Mb, Instead Of 1 Mb. You Will Get 15,360. Then You Take That Divided By 40 To See How Many Seconds It Will Take To Download The File, Which Will Give You 384. 384s In Turn Is 6m 24s For The File To Download.
Additional time required because of a miss it is generally the 30~40 cycles for Main Memory.
What are the all parts and all function of a central processing unit?
Two typical components of a CPU are:
The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
Why 8051 microcontroller called so?
Because it is 8- 8-bit controller (8000 series)
5- It has 5 interrupts
1- It has only one serial communication port
6 Fetching and decoding of any instruction takes three clock cycles How?
Incorrect. Fetching and decoding of any instruction takes a minimum of four clock cycles in the 8085.
T1 = ALE and address emission
T2 = Read initiation
T3 = Read completion
T4 = Opcode decode
T1, T2, and T3 are repeated for each additional byte of the instruction. In all cases, Twait, if indicated by not READY, is inserted between T2 and T3.
Can you run Windows 98 on an Intel Pentium 4?
Yes. A Pentium 4 would more than meet the minimum requirements. Some of the last low-end computers with Pentium 4s were sold with Windows Vista. If you are performing an upgrade on an older computer, you will also want to consider things like RAM and your graphics card in your decision.
Thermal design power (TDP), sometimes called thermal design point, represents the maximum amount of power the cooling system in a computer is required to dissipate.
1MB is 1024KB, 10240KB is 1024KB multiplied by 10, so its 10MB
What is the size of L1 and L2 cache?
Usually the size of the L2 cache will be larger than the L1 cache so that if data hit in L 1 cache occurs, it can look for it in L 2 cache.. If data is not in both of the caches, then it goes to the main memory...
Any of the major manufacturers; AMD processors such as a Sempron of the Athlon. Intel Pentium 4 etc..
The performance of any computer and hence it's software, benefit from having adequate memory installed. This is almost as important as the processor that's used.
Go for at least 512MB of memory. Most motherboards these days only support DDR memory, which is fast than SD RAM.
i think stick with p4 for that one because amd works allot better with games than large programs like image editing and mp3 encoding and do't listen to the rumours that the p4 fans die out all fans die out eventually

AMD Athlon 64. Go for 2+gHz, x2 (dual core). AMD processors are cheaper but just as good if not better than Intel. You just pay for the cheap 1 cent Intel sticker if you go for Intel. If you want Intel, that's okay too.
FAN IT TO THE MAX!!! Fans are cheap! Buy them!
I would suggest the Intel core 2 duo, comes cheap and delivers what you expect!!!!Frankly, I would go for one of the pentiums, maybe the Pentium 4 CPU. It's cheap, you can get 20 on eBay for $50 dollars, it's common, so you can just find a cheap motherboard that has a 775 socket. It's not as bad as Celeron or Atom, and it's not as expensive or ultra-powerful as the i3/i5/i7 CPUs. But, if you want one that is also cheap, but is more in the 64-bit range, go for a cheap 604 socket Xeon. SeanHolshouser
How do you connect an RCA output signal to the input on a VGA monitor?
via something like this: Composite and Y/C (S-Video) to VGA Monitor Converter

Can you use a Slot 1 CPU with a socket type motherboard?
No. Slot 1 cartridges were extremely complex. In addition to likely not fitting correctly in most, the connector would be extremely fragile, holding a large and bulky cartridge by a few fragile pins. No adapter was ever created for this reason. However, there are adapters to use Socket 370 processors on a Slot 1 motherboard. This is possible because Socket 370 processors are much smaller than Slot 1.
