(IP SECurity) A security protocol from the IETF that provides authentication and encryption over the Internet. Unlike SSL, which provides services at layer 4 and secures two applications, IPsec works at layer 3 and secures everything in the network. Also unlike SSL, which is typically built into the Web browser, IPsec requires a client installation. IPsec can access both Web and non-Web applications, whereas SSL requires workarounds for non-Web access such as file sharing and backup. IPsec is supported by IPv6. Since IPsec was designed for the IP protocol, it has wide industry support and is expected to become the standard for virtual private networks (VPNs) on the Internet.
Types of network marketing compensation?
I am in a 4x5 forced matrix, It has 4 people under each person and is 5 levels deep. it has the highest return per-capita of any network out there.
Level 1; Commission = 10%; People 4; Commission $48
Level 2; Commission = 10%; People 16; Commission $192
Level 3; Commission = 10%; People 64; Commission $786
Level 4; Commission = 30%; People 256; Commission $9,216
Level 5; Commission = 10%; People 1024; Commission $12,288
Total; 1364 People; Monthly commission $22,530 on a full matrix based on the company average of $120 per month. There are many bonuses and other rewards and no penalties. See my bio page for more info.
What part of the mac address is reserved for the vendor code?
The first six digits (first three pairs) of a MAC address identify the card vendor.

Which three labels correctly identify the network types for the network segments that are shown?
Network B -- WAN
Network C -- LAN
Network A -- LAN
What cable UTP or STP is preferred by the industry?
The UTP (Unshielded twisted pair) cable is preferred; it's far less expensive to install in large amounts.
What is the requirement of class b structural back fill?
1)90% of maximum dry density should be achieved on each test.
2)Frequency of tests is one test per 845 square meter.
3)You could test the 1st layer and the layer in case of multi-layers.
Overloading a network to keep users out is considered what?
A denial of service attack. (DoS)
This type of attack includes a variety of methods for denying legitimate users access to a network.
A Distributed Denial of Service attack (DDos) is more specific type of DoS attack which includes many, mostly infected, devices sending traffic towards a single source to overload the target and prevent normal access.
What are the well-known port numbers for the SFTP?
Like SCP, SFTP also piggybacks on SSH and utilizes tcp port 22 as its standard port.
It is Used for bit torrent P2P File Sharing, Bit torrent uses Ports
6902 - 6968 For File Data Transfer.
How many reams of paper 1 packet?
A standard packet of paper typically contains 500 sheets, which is equivalent to about 1 ream. Therefore, when referring to a packet of paper, it usually means you are getting 1 ream. However, the term "packet" can sometimes refer to different packaging configurations, so it's always good to check the specifics.
Explain the term mulitplexing and diffreitiate between fdm and tdm?
TDM (Time Division Multiplexing) and FDM (Frequency Division Multiplexing) are two methods of multiplexing multiple signals into a single carrier.
The advantage of FDM over TDM is in latency. Latency is the time it takes for the data to reach its destination. As TDM allocates time periods, only one channel can transmit at a given time, and some data would often be delayed, though it's often only in milliseconds. Since channels in FDM can transmit at any time, their latencies would be much lower compared to TDM. FDM is often used in applications where latency is of utmost priority, such as those that require real-time information.
FDM and TDM are often used in tandem, to create even more channels in a given frequency range. The common practice is to divide the channel with FDM, so that you have a dedicated channel with a smaller frequency range. Each of the FDM channels is then occupied by multiple channels that are multiplexed using TDM. This is what telecoms do to allow a huge number of users to use a certain frequency band.
Summary:
1. FDM divides the channel into multiple, but smaller frequency ranges to accommodate more users, while TDM divides a channel by allocating a time period for each channel.
2. TDM provides much better flexibility compared to FDM.
3. FDM proves much better latency compared to TDM.
4. TDM and FDM can be used in tandem.
FDM is used in 1st generation analog system whereas TDM is used in
2nd generation analog system.
don't do anything except look at it ok got it thank you
How you can shere data from two different computer?
The answer to this question requires more information. There are several people on here (myself included) who have the knowledge to help, but we would need more specifics. Consder reformatting your question.
Example:
"How can I share music files from one Windows XP machine to Windows Vista machine?"
OR
"How can I share word documents from my Mac to my Windows machine?"
Cheers

What is the purpose of a tftp server?
A TFTP (Trivial File Transfer Protocol) server is used to transfer files between different computer network within a network. This type of server is meant for use with a local area network (also known as a LAN). The purpose is of TFTP is to allow people to share information between computers in a closed system environment (such as an office or school).
