A PDF must be put into an external program after being exported to be edited, you can't make direct changes to it. This eliminates answer choice A.

You can print documents with other extensions besides .pdf, such as those of Word documents and such, it doesn't have to be a .pdf. This eliminates answer choice B.

Since you can't directly edit a PDF, C is a possible answer.

Files don't have to be saved as a .pdf, especially just for the first time. Whenever you save a file, first time or not, you can save it as anything, and there's no reason to have to save it as a .pdf. This eliminates answer choice D.

So the answer is C. it contains material you don't want changed.

Hope this helps!

Give a regular expression for binary numbers. They can be integers or binary fractions. A leading - sign is always allowed. Lead
Dmitry_Shevchenko [17]

Solution :

We have to provide an expression for the binary numbers. There can be binary fractions or integers. Whenever there is leading 0, it is not allowed unless the integer part is a 0.

Thus the expression is :

$(-+ \in )$ $[(1+10+11+100+101+110+111)(,000+,001+,010+,011+,111+,100+,101+,110)^*$ $(\in +.(0+1)^*(0+1))+(0.(0+1)^*(0+1))]$

Some systems provide file sharing by maintaining a single copy of a file. Other systems maintain several copies, one for each of
Natalka [10]

Answer:

Explanation:

When you have a single copy, a large number of concurrent updates that are supposed to go to a file may result in the user obtaining incorrect information. This incorrect information obtained them leads to the file being left in an incorrect state. When you have a lot of or multiple copies, then storage waste exist and the various copies might happen not to be consistent with respect one other. In summary, what happens is that

a) Using one copy saves space, but also the change might have an effect on all the users.

b) Using multiple copies avoids eliminates the change problem, while creating its own problems, using more space.

If the floating-point number representation on a certain system has a sign bit, a 3-bit exponent, and a 4-bit significand. What
vekshin1

Answer:

Normalization of storage is a typical method of storing the floating point number by shifting the decimal after the first figure of the number such as 1101.101 is normalized to 1.101101x23.

If the number that is in hovering point representation has 1 sign bit, 3-bit exponent with a 4-bit significant:

whenever the storage is normalized, then the biggest positive floating spot number in 2`s and the complement notation is 0.11112 x 23 = 111.12 =7.5

If the storage is returned to normal, then the minimum positive floating point number is 0.12 x 2-4 =0.000012 =1/32 = 0.03125.

Explanation:

Whenever the floating figure is keyed into the computer memory, then the first bit will be the sign bit, the next 8 bits are for exponent and 23 bits are used for storing significand. The array of exponents is from -127 to 128. While Exponent 127 stands for 0 and positive figures can be represented by values bigger than 127. The biggest floating point number will be represented as 0.111111.... 1111x 211111111
