Answer:

The brain uses chemicals to transmit information; the computer uses electricity. Even though electrical signals travel at high speeds in the nervous system, they travel even faster through the wires in a computer. Both transmit information. A computer uses switches that are either on or off ("binary").

Is the wireless network you own as secure as it should be? Examine your wireless network or that of a friend or neighbor and det

AleksandrR [38]

Answer:

See explaination

Explanation:

Wireless Security:

In a bid to examine the network you can use ipconfig /all command in windows or in the event where you are a linux user type in ifconfig to view all the configuration details of your network such as

indows IP Configuration

Host Name . . . . . . . . . . . . : myvpc-hb

Primary Dns Suffix . . . . . . . : example.com

Node Type . . . . . . . . . . . . : Hybrid

IP Routing Enabled. . . . . . . : Yes

Ethernet adapter Local Area Connection:- - - - - -

Connection-specific DNS Suffix . :- - - - - -

Link-local IPv6 Address . . . . . : fe65::ab56:ccb9:320c:524d%8(Preferred)

IPv4 Address. . . . . . . . . . . : 192.168.45.111(Preferred)

Default Gateway . . . . . . . . . : 192.168.15.1

DHCP Server . . . . . . . . . . . : 192.168.15.1

DHCPv6 IAID . . . . . . . . . . . : 201327615

Note: If you want to deeply examine the your network and to find security model go with Wireshark application.It will help you to capture the data packets easily using GUI.Also it will provide other details like transmission control protocols,etc.

To take your network to highest level i.e. to make it more secure you can use:

1.Firewalls like application gateways,packet filtering,hybrid systems.

2.Crypto cable routers

3.Virtual private networks, etc.

Estimation of cost and the time to increase the level is solely depends on the type of the architecture you want to use for the network building structure.Also the size of the network will be responsible for the cost and time.

In case of any attack on your computer it depends on the size of the data on the computer disc and the bandwidth of the network to which your computer is connected to replace all data. The faster the bandwidth of the network,faster the data replacement rate.

In a folder hierarchy, the top level is referred to as which of the following?

Vesnalui [34]

Answer:

B. root

Explanation:

Every user in Linux is assigned a folder from which they can store their files. The interpreter allows you to abbreviate your route with the “~” symbol. The ls command without any additional data shows the files in the current directory, but if after the name of the command a path is written, it shows the files in that path. Therefore, the ls ~ command shows the files in the user's folder.

In addition to the folders and files created by the user or programs, every Linux folder has two subfolders defined by default:

“..”: It is the top level folder in the file hierarchy that contains it. This subfolder is also present in the root of the filesystem (the folder with absolute path “/”), but points to itself.

“.”: It is the folder itself that appears as if it were also a subfolder. It can be considered as a "self-reference" or pointer to itself.

These folders are normal folders in the system for all purposes; that is, they can be used on routes. For example, the path /dirA/dirB/dirC/../fichero2.txt refers to the file that is stored in the dirB folder, since from dirC, the folder .. points to its predecessor, dirB. The following figure shows the interpretation of this route as well as the equivalent of the “..” and “.” Folders.

riadik2000 [5.3K]

Answer:

A private IP address should be implemented but a PAT and a static NAT should be configured for the computers and the intermediate devices respectively.

Explanation:

There are two types of IP addresses, they are public and private addresses. The public address is an IP4 address routable on the internet while the private address is not routable.

Internet service providers do charge for the use of public IP addresses they render, which can be very costly. To reduce the company's expenses on the internet, the company is networked with private addresses and are mapped for network address translation ( NAT) which assigns a public global address to devices accessing the internet.
