Microprocessors

the different operating modes of 8255 are as follows

1)bsr mode

2)i/o mode

-bsr mode can only program using port c and is used when d7=0 in control word

-i/o mode can be used for all ports a,b,c(upp),c(low) respectively and is used when d7=1

1 More the RAM more the computer speed

The instruction 20H is RIM (Read Interrupt Mask). The instruction 57H is MOV D,A. The contents of PC after these two instruction will be 2 greater than it was before starting.

As the name suggests... four. Two on each of two dies.

A minimum mode of 8086 configuration depicts a stand alone system of computer where no other processor is connected. This is similar to 8085 block diagram with the following difference. The Data transceiver block which helps the signals traveling a longer distance to get boosted up. Two control signals data transmit/ receive are connected to the direction input of transceiver (Transmitter/Receiver) and DEN* signal works as enable for this block. This is the same as Read cycle Timing Diagram except that the DT/R* line goes high indicating it is a Data Transmission operation for the processor to memory / peripheral. Again DEN* line goes low to validate data and WR* line goes low, indicating a Write operation In the maximum mode of operation of 8086, wherein either a numeric coprocessor of the type 8087 or another processor is interfaced with 8086. The Memory, Address Bus, Data Buses are shared resources between the two processors. The control signals for Maximum mode of operation are generated by the Bus Controller chip 8788. The three status outputs S0*, S1*, S2* from the processor are input to 8788. The outputs of the bus controller are the Control Signals, namely DEN, DT/R*, IORC*, IOWTC*, MWTC*, MRDC*, ALE etc. These control signals perform the same task as the minimum mode operation. However the DEN is an active HIGH signal which has to be converted to active LOW by means of an inverter.

Check the motherboard, see if the CPU is installed correctly

Each assembly/machine instruction has a unique value which indicates what operation is to be performed, what addressing mode, etc. Typically one of these codes or bit(s) within the code would indicate if this were a 16 bit code. In this way, if the CPU received an 8 bit code with no extension for 16 bit mode, it would run the 8 bit code (assuming that when 8 bits instructions were written it didn't have to be future/forward compatible).

I assume you mean a 32-bit processor. In either case, this depends on the software. Typically secondary programs (Word processors, games, etc) have a 32-bit build included with them / hard coded into their actual 64-bit compile, and will typically work in both environments. This isn't something that will always be the case, it is sort of a fail-safe since so many people haven't made the 64 bit jump yet.

Operating systems, hardware drivers, and primary programs (Integrated OS programs such as Windows Media Player and Windows Installer) are incompatible with a 32-bit processor if they are compiled in a 64-bit environment.

This means do NOT get a 64-bit operating system if you still have a 32-bit processor. Some things may or may not work, but it will be more trouble than its worth either way.

This is not true in reverse: A 64-bit processor will have no issues running 32-bit programs, operating systems, or drivers.

Core 2 Duo is FASTER. Pentium M is based on OLD technology and run on a SINGLE PROCESSING CORE whereas the CORE 2 DUO has 2 PROCESSING CORES. It has higher CLOCK SPEED, FSB, CACHE. Simple!

Socket 478 is a processor socket used by certain versions of the Intel Pentium 4 and their Celeron counterparts. It consists of 478 contacts (pin holes) in a FC-PGA configuration. The Socket 478 format was replaced by the Socket 775 format.

Oh, yeah. Buy a cooling tray.

i dnt know

what was the operating temperature of the cpu for the intel celeron g540

This all depends. It is possible that the "broken" pin was removed at the factory. Some of the 486 CPUs were like that. The SX chips likely were missing a few pins. Or, you might be lucky and the pin could be a redundant ground or not connected internally. However, more than likely, it just won't work or you will be missing some functionality.

Q6600 is a 64 bit processor, but it can execute in 16 and 32 bit modes.

The CPU (central processing unit) chip today includes one or more ALUs, one or more AGUs, and one or more FPUs. The ALU is the Arithmetic and Logic Unit, and that is used for common tasks. It might also be known as the Execution Unit. The AGU is the Address Generation Unit, and it is used for addressing memory. The FPU is the floating point unit, and that is for working with complex numbers. Modern CPUs also include a memory controller.

Then there is the GPU, or Graphics Processing Unit. That is what renders the graphics and outputs a display. It also addresses the video memory and also performs graphics-related tasks so the CPU doesn't have to, thus speeding up graphics.

There is the Northbridge chip. That is part of the chipset and includes tasks such as being the memory controller, providing a graphics bus (AGP controller on somewhat older PCs), and providing a bus for the Southbridge which controls the rest of the computer past that point. Most of these functions are now integrated into the CPU.

There is also a Southbridge chip. It is the circuitry which ties to the peripheral devices, the peripheral bus, the USB controller, the hard drive controller, the floppy controller (if the system has one), integrated sound, the mouse, the keyboard, and the ROM BIOS.

There is the memory, it is what holds the operating system and programs while they are in use.

There are the storage devices. The hard drive is the most common device in this class, and there are also CD/DVD devices.

There are input devices. These are your mouse, keyboard, any tablets you might have, or similar.

There are output devices. These would include the video card, the monitor, and any printers and plotters.

There are networking devices. These include network and WI-FI cards and are used to connect your PC with other PCs.

There is the ROM BIOS which is a chip containing the code used to bring up the PC. That is what initializes the computer, brings up the CPU, provides basic functionality for devices, and loads the operating system. Once the OS is loaded, it takes over most of the functions that the BIOS provides.

CPU = central processing unit

The term "microprocessor" and CPU are roughly equivalent, although the purists out there will probably say that CPUs are for larger machines and microprocessors are for embedded system or PC class machines.

The answers: these are basically synonymous terms for all intensive purposes.
