A cargo hub is a transshipment or transfer point that provides cargo transfer and handling services. Services can include packaging, warehousing, sorting, and trade services. Cargo hubs usually involve a major facility such as an airport or seaport.

You need to install all updates for your OS, and check the latest version of drivers for your network adapter. Also make sure that you do not have trojans, viruses and so on.

-They let two network segments appear as one network to connected workstations.

-Their primary function is to keep traffic for one segment away from the other segment.

CDMA technology uses spread spectrum concept thereby giving users unique code to de-spread the information being sent to them. so CDMA is secure and occupies a large bandwidth of information compared to GSM technology.

They check packets by source address

They check packets by destination address

Each IP packet has information about the destination, and the origin. "Reply IP address" probably refers to the origin; it is to the origin that any reply will have to be sent.

The session layer is meant to store states between two connections, like what we use cookies for when working with web programming.

The presentation layer is meant to convert between different formats. This was simpler when the only format that was worried about was character encoding, ie ASCII and EBCDIC. When you consider all of the different formats that we have today(Quicktime, Flash, Pdf) centralizing this layer is out of the question.

TCP/IP doesn't make any allocation to these layers, since they are really out of the scope of a networking protocol. It's up to the applications that take advantage of the stack to implement these.

Yes, in fact, that is a common way to set up a network.

Wireless communication refers to ANY communication done with radio-waves instead of wires. Mobile computing simply means using a laptop on it's own imternal battery.

DoS

The difference between a router and a switch has to do with the layers of the OSI model that they reside in. A switch is a layer 2 device, which means it relies on the MAC (physical) address for switching packets. A router is a layer 3 device, using the network (logical) address.

A router also can forward packets to another network; a switch does not do that. In addition, a switch forwards all broadcast packets whereas a router does not forward broadcast packets.

A hub creates the most traffic collisions.

The three factors determining which network an organization should use is the cost, the type of network, and the size of the network.

Optimum should be able to be used wireless as wired

Good luck!

The Internet relies on primarily the TCP/IP protocol suite.

A clock-rate is the speed at which the Serial connection sends data to another router and each connection must match the others clock-speed or a speed mismatch error will occur. For packet tracer, the clock-rate has no effect.

Wireshark is a perfectly legal network troubleshooting tool. However it is possible to use it in illegal ways, like many other tools.

4. Set the switch priority to a smaller value than that of the other switches in the network.

A dedicated host server is a server operating system for which a client pays to use its infrastructure, power system, support and bandwith. There are managed, unmanaged and semi-manages servers for different levels of service.
