How do you identify pin connections on AND gate IC chips?

User Avatar

Asked by Wiki User

To identify pin connections on an AND gate IC chip, refer to the datasheet provided by the manufacturer. The datasheet will have a pinout diagram showing the location and function of each pin on the chip. Additionally, you can use a multimeter to test for continuity between pins to confirm their connections.

Explain how the properties of life emerge from complex organization?

User Avatar

Asked by Wiki User

The properties of life, such as growth, reproduction, and adaptation, emerge from complex organization because living organisms have highly organized structures and processes at various levels, from cells to organ systems. This organization allows for the coordination of activities necessary for life, such as metabolism and responding to stimuli. Through intricate interactions and feedback mechanisms, complex organization enables living beings to exhibit the characteristics and behaviors associated with life.

Asked by Wiki User

Yes, spaces count as bytes in emails because they are characters that are included in the overall size of the email message. Each character, including spaces, adds to the byte count of the email.

What is the difference between the Intel 8085 and the Intel 8086?

User Avatar

Asked by Wiki User

The Intel 8085 is an 8 bit microprocessor created in 1977.

The Intel 8086 is a 16 bit microprocessor created in 1978. The 8086 was the first chip to start the x86 architecture family.

8085 contains 16-bit address bus and 8-bit data bus

8086 contains 20-bit address bus and 16-bit data bus..

In 8085 the clock speed is 3MHZ

where as in 8086 the clock speed is 5MHZ.
there are two differences btw 8085&8086

1. 8086 has 6 byte queue but 8085 has 4 byte queue

2. 8086 has 16 bit data bus where as 8085 has 8 bit data bus

Why is it if MARIE has 4k words of main memory and addresses must have 12 bits?

Asked by Wiki User

4K (4096) of addressable space is defined by 12 bits of address space, because 212 = 4096.

How general purpose registers increases speed of operation?

User Avatar

Asked by Wiki User

I am not quite sure how significant this is. The reason, however, is that accessing a register, which is part of the CPU, is faster than accessing RAM memory, which is located on a separate chip.

What is the difference between 32 bit microprocessor and 64 bit microprocessor?

User Avatar

Asked by Wiki User

The fundamental difference between a 32-bit and 64-bit microprocessor is what their names suggest: the size of the basic integer operations, also called the 'native' size of a CPU's calculations. The native size of a CPU determines a whole bunch of related characteristics.

For instance, all integer calculations are done using the native size; this matters in terms of performance for several reasons:

  • if you add two integers smaller than the native size, it requires only a single operation.
  • if you add two integers larger than the native size, you must perform 3 operations (add the upper values, add the lower values, then combine).

For instance, if you wanted to add two 20-bit numbers, on both the 32-bit CPU and 64-bit CPU it would require a single operation. However, if you wanted to add two 40-bit numbers, it would require only 1 operation on a 64-bit CPU, but 3 operations on a 32-bit CPU.

The native size of a CPU also determines things like the maximum addressable memory - thus, a 32-bit CPU can address up to 2^32 = 4GB of memory, while a 64-bit system can address up to 16 Exabytes. It also determines the minimum size of information that has to be processed - when fetching information from caches and memory, no operation can be done with information less than the native size. Thus, 64-bit CPUs are more demanding on memory subsystems, as they need to process information in 64-bit chunks, rather than 32-bit ones.

Which protocol is used to convert logical IP addresses to physical MAC addresses?

Address Resolution Protocol (ARP)

ARP is primarily used to translate IP Addresses to Ethernet MAC Addresses.

What is the difference between minimum mode and maximum mode?

User Avatar

Asked by Wiki User

Minimum mode in the 8086/8088 provides the functionality of the 8288 bus controller, which means that functions like HOLD, HLDA, WR-, M/IO-, DT/R-, DEN-, ALE, and INTA- come off of the 8086/8088.

Maximum mode means that these functions come off of the 8288, in somewhat enhanced form, and the pins are replaced with new meanings like RQ-/GT0-, RG-/GT1-, LOCK-, S2-, S1-, S0-, QS2, and S21, giving the processor extra capabilities.

Explain about segment registers in 8086MP?

User Avatar

Asked by Wiki User

There are four segment registers in the 8086/8088 processor, CS, DS, ES, and SS, also known as Code Segment, Data Segment, Extra Segment, and Stack Segment. Any time an address is generated by the processor, it is added to the value of one of the segment registers, after that segment register is effectively multiplied by 16, or left shifted four bits, in order to generate the physical address that accesses memory. This gives an effective address range of 20 bits, or 1mb, but note that only 64kb is addressable through any segment register at one time, unless you stop to change the contents of that segment register. This is known as a segmented architecture. By default, the CS register is used when fetching instructions, the DS register is used when accessing data, the SS register is used when accessing the stack, and the ES register is used during certain string type instructions. If desired, an instruction prefix can be used to override, such as forcing use of CS instead of DS when using a table contained within opcode space.
