Answer:

Interrupts.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.

The four (4) input-output (I/O) software layers includes the following;

I. User level software: it provides user programs with a simple user interface to perform input and output functions.

II. Device drivers: it controls the input-output (I/O) devices that are connected to a computer system through a wired or wireless connection.

III. Device-independent OS software: it allows for uniform interfacing and buffering for device drivers.

IV. Interrupt drivers (handlers): it is responsible for handling interruptions that occur while using a software on a computer system.

An interrupt is a signal from a program or device connected to a computer and it's typically designed to instruct the operating system (OS) that an event has occurred and requires an attention such as stopping its current activities or processes.

In conclusion, the computer term that Selma is describing is interrupts.

What is the preferred procedure for putting customers on hold​
vesna_86 [32]

Answer/Explanation:

Explain the reason you need to put the caller on hold.

Ask for the person's phone number, in case the conversation is cut off.

Promise to return in a minute—or your best estimate of how long the hold will last. If you think the delay will be longer than a couple of minutes, ask for a number and a time when you can call back.

If, despite your best efforts, the delay is taking longer than anticipated, check in with the caller so that he doesn't feel abandoned. Again, offer to call back, "rather than keep you holding."

When you return to the phone, apologize for the inconvenience and thank the caller for his patience.

Use the caller's name frequently to add a sense of connection.

The first step you can take when putting a caller on hold and making it a satisfying experience is a systematic one. When a caller is on hold, 60 seconds seems like an eternity, so see if you can program the phone system to play music (calming classical or jaunty jazz is best) to break this perception of an interminable wait. Aside from that, however, putting someone on hold in a professional way depends on your behavior. The golden rule to keep in mind is as follows: how would you like to be treated if you were on the other end of the line?

marshall27 [118]

Answer:

a. 6 bits

b. 1

Explanation:

Ans (a)

40 Characters need to be represent by binary coded Zebronian (BCZ) , So You will need 6 bits.

5 bits wold only give you 32 = 2 x 2 x 2 x 2 x 2 unique characters.

So 6 bits would allow you to represent 64 characters.

Ans(b)

BCD = Binrary Coded Decimal is very common in electronics, particularly it displays numerical data.

BCD Encodes each digit of a decimal number into 4 digit binary form.

Each decimal digit is indiviidually converted to oits binary equivalent

For Example : 146 , the decimal degits are replaced by 0001 , 0100 and 0110 respectively

Addition

1 0 = 10 is binary value of 2 2

+1 1 = 11 is binary value of 3 + 3

---------- -----------

1 0 1 5 Ans

Subtraction

1 1= binary value of 3 3
