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:
import os, sys, stat
from stat import *
command = 'find ' + sys.argv[1] + ' -name *' + sys.argv[2] + '*'
print(command)
totalFiles = os.popen(command).read()
totalFiles = totalFiles.split()
totalSize = 0
for line in totalFiles:
statinfo = os.stat(line)
if stat.S_ISREG(statinfo.st_mode):
print(line, statinfo.st_size, 'bytes')
totalSize += statinfo.st_size
else:
print(line, '...')
print('Total file size:', totalSize, 'bytes')
Explanation:
- According to command line arguments, build the find command.
- Store the product by executing the command.
- Loop through all files in the output list using the for loop.
- Display the file name and size, If the file is regular otherwise just display the file name.
Answer:
Variables. Variables are used to store items in a database so that humans and the computer can better understand the program, and use later on for referencing.
Answer:
A hard drive disk for computer storage!
Explanation:
Answer:
In computing, extract, transform, load (ETL) is the general procedure of copying data from one or more sources into a destination system which represents the data differently from the source(s) or in a different context than the source(s).
Data extraction involves extracting data from homogeneous or heterogeneous sources; data transformation processes data by data cleansing and transforming them into a proper storage format/structure for the purposes of querying and analysis; finally, data loading describes the insertion of data into the final target database such as an operational data store, a data mart, data lake or a data warehouse. Hope this helps! PLEASE GIVEE ME BRAINLIST!!! =)
