Answer:

Scanner.

Explanation:

Scanner refers to an input device which transfers information and images from physical documents to computer files. It is simply an electronic device that is used to digitally scan or copy data (informations) from a hardcopy document such as photographs, paper files, printed texts etc and then converted to a digital computer file in formats such as png, or jpeg. The scanner is a device which avail users the ability and opportunity to view, edit and transfer hardcopy document on a computer system in soft-copy.

Majority of the scanners used around the world are flatbed scanners and as such have a flat glass surface for scanning documents. Basically, all scanners are to be used with a device driver software pre-installed on the computer before the configuration of the scanner.

<em>Other types of scanners are drum scanners, contact image sensor (CIS) scanner, CCD scanner, planetary scanner, 3D scanner, Roller scanner etc</em>.

STatiana [176]

Answer:

Check the explanation

Explanation:

Consider the following data

Let S represent the average number of segments

Let H represent the average number of holes

The probability that there is a hole immediately after the segment is 0,

So, when there are s segments in memory, there must be

$s X 0.5 or \frac{s}{2}$

Best-fit: this analyses the entire memory partitions available

a. you’ll have to selects the least one which is capable of handling the process exec.. Memo, space wastage .n be reduced In some cases, there will be no memory wastage

The average length a search is $\frac{s}{2}$

First-fit: This technique assigns Me the first hole that is big enough.

Searching Marts at the starting of Me set of holes.

The searching will be closed immediately a user gets a free hole that is big enough.

On an average it searches half of the set of holes.

The average length of search is Y2

$\frac{s/2}{2} = \frac{s}{4}$

What two units are used to measure the frequency and amplitude of a sound wave?

Lerok [7]

Answer:

A. Hertz ----f amplitude.

Explanation:

The rules of physics confirm that frequency is measured in HERTZ and the amplitude is measured in Decibel. And hence, the correct option here is certainly the first option as it states that the frequency is measured in HERTZ and the amplitude is measured in Decibel. Hence, the first one is the correct choice for this question.

What variation of a dictionary attack involves a dictionary attack combined with a brute force attack, and will slightly alter d

Galina-37 [17]

Answer:

D) Hybrid Attack

Explanation:

This type of attack is a blend of both a dictionary and brute force attack. The meaning of this is, while a dictionary attack method would capture a wordlist of passwords, the brute-force attack would be applied to each of password captured.

Given the statement: int list[25]; The index can go from 0 to 25 inclusive withoutgoing beyond the end of the array.true or fals

k0ka [10]

Answer:

False.

Explanation:

When we create an array of size n, then it's index will starts from 0 to n-1. Array index starts with 0 because the first element of the array holds the memory location that refers to 0 element away.Similarly 2nd element of array is 1 distance away from that location. That is why index starts with 0 and goes to n-1 if the size is n.

In the question question, int list[25] is given. So the index will be from 0

to 25-1 only.If index will goes to 25 then it will go beyond the array.
