<span>"rws" means that the user has permissions to read, write and setuid. "r" means the user can read the file and "w" means that the user can write to the file. "s" stands for "setuid" (set user id) is a permission bit that allows the users to execute a program with the permissions of its owner. The "s" can also mean "setgid" (set group id) is a bit that allows the user to execute a program with the permissions of the group owner.</span>

Outline the steps necessary to prepare a storage device for storing files. Identify and briefly describe the tools used to prepa
Fantom [35]

Answer:

Outline the steps necessary to prepare a storage device for storing files.

  1. Link the storage unit to a network, whether it be a laptop computer or a mobile device.
  2. Firewall it with sufficient anti-virus so that it also does not affect the linked system.
  3. The program must auto-install the storage device on the network after quarantine, and authorize it.
  4. Test the file that requires to be moved to the storage device, then upload it to the storage device after anti virus is safe.
  5. Should not directly pull the storage device out of the network, select the exit device option correctly and only then remove the device after it has been accepted.

Identify and briefly describe the tools used to prepare a storage device for storing files.

<em>EFSDump -</em> Users can share encrypted files by carrying certificates by using EFSDump. It is usually very time consuming to audit the users who have privileges. But it is very simple to list users who have access to encrypted files using EFSDump.

<em>SDelete -</em> Suppose Windows operating system eliminates the index and prevents access when we delete a file. All the same, attackers can still recover the contents of the file. Files that are encrypted by EFS leave the file behind on the disk. Using the SDelete tool we can modify free space to prevent the recovery of deleted files.

Explain why file systems are critical components of an operating system. What is their purpose?

Hypothetically defining file system is nothing more than the way files are called and logically organized for storage.

Ex: DOS, Windows, and Unix-based operating systems all contain various file systems where data is organized in tree structure.

Usually defines the naming of files, how long the suffix can be. The file system often includes a format indicating the access to a file.

Specify the file system or file systems that would be available with that operating system.

A file system controls the mechanism by which data is stored and accessed on a disk. This deals mainly with internal disk operations such as naming files, records, directories, documentation, storage management, and other protocol accesses.

  1. FAT (File Allocation Table)
  2. NTFS (New Technology File System)

Describe from an administrator perspective what is necessary to prepare a storage device for access by a user.

Connection to the storage unit is equipment-oriented. The Windows Explorer summary contains optical drives, USB keys and hard drives as separate devices, making it much easier to navigate a new computer.

To connect a Linux computer you must mount the drive by connecting it to a directory.

Usually mounting a device is a manual operation, since only the administrator determines which directory the system attaches to.

Graphical interfaces are seldom seen on Linux servers. When you plug a storage device into a USB port on your computer, nothing can happen.

Usually the mount command looks like mount/dev / sdb1/mnt, where /dev / sdb1 is the system and /mnt is the directory you want to mount it.

List a few ways that a user can utilize a file system.

System output can be improved not only by choosing the most appropriate file system(s) but also by using the various choices available for most file systems.

There are variations in the number of options depending on the specific file system, and some options can only be set at the time of development of the filesystem, even though it can be modified afterwards.

Which of the following expressions yields an integer between 0 and 100, inclusive? Question 5 options: (int)(Math.random() * 100
Alex17521 [72]

Answer:

(b) (int)(Math.random() * 101)

Explanation:

Given

min = 0 --- minimum

max =100 --- maximum

Required

Java expression to generate random integer between the above interval

The syntax to do this is:

(int)(Math.random((max - min) + 1) + min)

Substitute the values of max and min

(int)(Math.random((100 - 0) + 1) + 0)

Simplify the expression

(int)(Math.random(100 + 1) + 0)

(int)(Math.random(101) + 0)

(int)(Math.random(101))

Hence, the right option is:

(b) (int)(Math.random() * 101)

MakcuM [25]

A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment

Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :

EMI

RFI

Explanation:

  • EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
  • During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
  • EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
  • Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
  • The internal circuits of personal computers generate EM fields in the RF range.

How does a router handle a packet destined for a network that is not listed in the routing table?
kogti [31]
The packet is dropped or discarded. By default, a router will send packets to a network that has been listed in the routing table. If it happens that the network is not listed, the packet will be discarded or dropped. Packets that do not have a default route or gateway of last resort are dropped.
