Explain the statement what if your PC is stoned on computer?
Stoned is the name of a boot sector computer virus created in 1987.
Notable for being an early boot sector virus, it was thought to have been written by a university student in Wellington, New Zealand[1][2] - and by 1989 it had spread widely in New Zealand and Australia.[3] It was one of the very first viruses, and was, along with its many variants, very common and widespread in the early 1990s.[4]
When an infected computer started, there was a one in eight probability[5][6] that the screen would declare:
Your PC is now Stoned!
The phrase is found in infected boot sectors of infected floppy disks and master boot records of infected hard disks along with the phrase "Legalise Marijuana".

Remote Supervisor Adapter
PCI adapter which simplifies remote system management by providing around-the-clock remote access to the server. The RSA monitors the server and sends out alerts to designated recipients via LAN, pager, email or SNMP if a failure is detected.

Peers are those people, who have not yet finished downloading and are downloading and uploading at the same time. If you have got choice, it's almost always better to pick a torrent with the most seeders.
It is the loss of data from the coaxial cable during transmission .
What decisions do routers make as a packet enters an interface?
It determines which local IP on a given Router Table, be it DHCP or static, that packet is assigned to.
Peers
A peer IP is used by a server to communicate directly with other server(s). Meaning, two servers use peer IP addresses so nothing has to go through a third party server in between. This is needed to speedup the data transfer between two servers. An example of this would be online gaming or file sharing...
Someone that you may know that can help you with a conflict or an issue that you are dealing with.
What are two functions of the data link layer?
What are two functions of the data link layer? (Choose two.)
It segments and reorders the data.
It exchanges data between programs that are running on the source and destination hosts.
***It controls how data is placed onto the media.
It generates signals to represent the bits in each frame.
***It encapsulates each packet with a header and a trailer to transfer it across the local media.
============================
1. Data Link layer do not reorder data - this is the job of Transport Layer
2. Programs are at Aplication Layer
4. Physical Layer generate signals
What is the maximum data rate for ISDN BRI?
ISDN BRI is a Basic Rate Interface for ISDN networks (Intergrated Services Device Network). It consists of 2 Channels: B+D. B channel is used for data and voice and consists of two 64Kbps channels=128Kbps. D channel is used for the signal and control of the interface and is 16Kbps. Together the B+D chanels are refered to as 2B+D. The maximum data rate on a BRI is therefore 128Kbps.
NOTE:PRI is Primary rate Interface which uses 23x64Kbps B channel and 1x64Kbps D channel (T-1)

What information about a peer would need to establish a VPN?
Peer IP address
Encryption and Algorithms
Pre-Shared Key
mode(agressive/main)
DH-Group
local ip address (other site of VPN)
that is the conbfiguartion details needed..
#Configure terminal for configuration mode #exit for previous mode #ctrl+z for set up mode

If the propagation delay is very long, as in the case of a space probe on or near Mars or Venus, forward error correction is indicated. It is also appropriate, in a military situation in which the receiver does not want to disclose his location by transmitting. If the error rate is low enough that an errorcorrecting code is good enough, it may also be simpler. Finally, real-time systems cannot tolerate waiting for retransmissions.
