Before a packet is sent across the network, it must be told the IP address of where it's going, and the IP address of where it's come from.There are presently two standards of IP address: the IPv4 and the IPv6. The details are beyond the scope of this module, ...
Network bandwidth is a measurement indicating the maximum capacity of a wired or wireless communications link to transmit data over a network connection in a given amount of time. Typically, bandwidth is represented in the number of bits, kilobits, megabits or gigabits that can be transmitted in ...
Networks enable the transfer of information between two systems, including between two computers or applications. The Open Systems Interconnection (OSI) Model breaks down several functions that computer systems rely on to send and receive data. In order for data to be sent across a network, it wi...
The data might travel a completely different path to get back to you. This flexible approach to data transfer is part of what makes the Internet such a powerful tool. Let's take a closer look at how information travels across the Internet. Packet, Packet, Who's Got the Packet? The ...
Your computer is connected to the Internet. Briefly explain how information is sent across the Internet. Be sure to discuss TCP/IP and packets. Internet: It is a global computer network providing a variety of information and communication facilities, consisting of ...

Defines how to send raw data across a physical medium, such as Ethernet or a modem. This is sometimes called the link layer or host-to-network layer. o 物理层。定义如何通过物理介质发送原始数据,例如以太网或调制解调器。 有时也称为链路层或主机到网络层。 It’s important to understand the ...
Network Traffic Definition Network traffic is the amount of data moving across a computer network at any given time. Network traffic, also called data traffic, is broken down into data packets and sent over a network before being reassembled by the receiving device or computer. ...
Encryption:IPsec encrypts the payloads within each packet and each packet's IP header (unless transport mode is used instead of tunnel mode — see below). This keeps data sent over IPsec secure and private. Transmission:Encrypted IPsec packets travel across one or more networks to their destina...
