Its binary! In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" (zero) and "1" (one).
Answer: ensuring that a system is not changed by a subject that is not authorized to do so
Explanation: Access control refers to pribcues which are employed in the bid thlo ensure the security of data and information. It provides the ability to authenticate and authorize access to information and data thereby preventing unwarranted access and tampering of the information. Integrity in terms of data security and access control is is concerned with modification to an existing or original data by unauthorized sources. When unauthorized addition or subtraction occurs on a data, the integrity of such data has been compromised. Therefore, authorization is required whenever a source is about to access certain information whereby only those with the right authorization code will be allowed, Inputting an incorrect pass code after a certain number of tries may result in system lock down as access control detects a a possible intrusion
Answer:
Link
Explanation:
A Link is a term often used in computer application, data, or file management, that allows a user to carry out the operation of transferring data or information from one file to another often referred to as a target.
There are two types of major links, these include Symbolic links and Hard links.
Hence, in this case, A connection between files that allows data to be transferred from one file to another is a LINK
Answer:
Following are the code to this question:
userVal = input()#defining a variable userVal for input the value
x= 0#defining variable x that holds a value 0
for j in userVal:#defining for loop to count input value in number
if not(j in " .,"):#defining if block that checks there is no spaces,periods,and commas in the value
x += 1#increment the value of x by 1
print(x)#Print x variable value
Output:
Hello, My name is Alex.
17
Explanation:
In the above-given code, a variable "userVal" is defined that uses the input method for input the value from the user end, in the next line, an integer variable "x" is defined, hold value, that is 0, in this variable, we count all values.
- In the next line, for loop is defined that counts string value in number and inside the loop an if block is defined, that uses the not method to remove spaces, periods, and commas from the value and increment the value of x by 1.
- In the last step, the print method is used, which prints the calculated value of the "x" variable.
5(3x - 7)
distribute the 5 to both 3x and -7
15x - 35 is equivalent
hope this helps
