natta225 [31]

Hello,

Well my advice for Sara when using the web would be 3 things.

1: Never tell anyone where you live,Your name, Or any other personal information.

This is important as it will keep you safe and others that are in your family.

2: Get anti virus hardware on your devise.

This will help to stop bad people, and bugs/glitches,this will also protect you from information thieves.

3: Make sure to keep your passwords saved on paper.

I know a lot of people use, google(ect.) to save there passwords to make everything easy, but a good way to never loss them is to wright them down.

Have a great day!

What is an 8086 microprocessor used for
Liula [17]
A sixteen bit microprocessor chip used in early IBM PCs. The Intel 8088 was a version with an eight-bit externaldata bus.

The Intel 8086 was based on the design of the Intel 8080 <span>and </span>Intel 8085 (it was source compatible with the 8080)with a similar register set, but was expanded to 16 bits. The Bus Interface Unit fed the instruction stream to theExecution Unit through a 6 byte prefetch queue, so fetch and execution were concurrent - a primitive form ofpipelining (8086 instructions varied from 1 to 4 bytes).

It featured four 16-bit general registers, which could also be accessed as eight 8-bit registers, and four 16-bit indexregisters (including the stack pointer). The data registers were often used implicitly by instructions, complicatingregister allocation for temporary values. It featured 64K 8-bit I/O (or 32K 16 bit) ports and fixed vectored interrupts.There were also four segment registers that could be set from index registers.

The segment registers allowed the CPU to access 1 meg of memory in an odd way. Rather than just supplyingmissing bytes, as most segmented processors, the 8086 actually shifted the segment registers left 4 bits and addedit to the address. As a result, segments overlapped, and it was possible to have two pointers with the same valuepoint to two different memory locations, or two pointers with different values pointing to the same location. Mostpeople consider this a brain damaged design.

Although this was largely acceptable for assembly language, where control of the segments was complete (it couldeven be useful then), in higher level languages it caused constant confusion (e.g. near/far pointers). Even worse, thismade expanding the address space to more than 1 meg difficult. A later version, the Intel 80386, expanded thedesign to 32 bits, and "fixed" the segmentation, but required extra modes (suppressing the new features) forcompatibility, and retains the awkward architecture. In fact, with the right assembler, code written for the 8008 canstill be run on the most <span>recent </span>Intel 486.

The Intel 80386 added new op codes in a kludgy fashion similar to the Zilog Z80 and Zilog Z280. The Intel 486added full pipelines, and clock doubling (like <span>the </span>Zilog Z280).

So why did IBM chose the 8086 series when most of the alternatives were so much better? Apparently IBM's own engineers wanted to use the Motorola 68000, and it was used later in the forgotten IBM Instruments 9000 Laboratory Computer, but IBM already had rights to manufacture the 8086, in exchange for giving Intel the rights to its bubble memory<span> designs.</span> Apparently IBM was using 8086s in the IBM Displaywriter word processor.

Other factors were the 8-bit Intel 8088 version, which could use existing Intel 8085-type components, and allowed the computer to be based on a modified 8085 design. 68000 components were not widely available, though it could useMotorola 6800 components to an <span>extent.

Write a statement that compares the values of score1 and score2 and takes the following actions. When score1 exceeds score2, the
vaieri [72.5K]

Answer:

player1Wins = player1Losses = player2Wins = player2Losses = tieCount = 0

score1 = 10

score2 = 10

if score1>score2:

   player1Wins=player1Wins+1

   player2Losses=player2Losses+1

   print("player1 wins")

elif score2>score1:

   player2Wins=player2Wins+1

   player1Losses=player1Losses+1

   print("player2 wins")

else:

   tieCount=tieCount+1

   print("tie")

Explanation:

Since your indentation can not be understand what you give us, please try to do it as you see in the answer part.

Although it seems that this is a part of the code, it is normal that you get errors. However, since you keep track of the variables, it is better to initialize the variables that will keep the counts. Since initially, they are 0, you may set them as 0. Also, if you assign the values to the scores, probably you would not get any error. This way, you may test your code as I did.

Other than these, in the else part you do not need to write "score1=score2", because if score1 is not greater than score2 and if score2 is not greater than score1, this already implies that they are equal

What is an undirected graph?
ella [17]

Answer: An undirected graph is the graph that has the connection of the objects in the form of bidirectional edges.This graph is formed for by the attachment of the collection of the objects which get displayed in the form of network and thus, also known as the undirected graph.

The graph is formed by the nodes or objects getting connected and form edges or link(which is typically in the form of line).
