When a router converts the client’s private IP address into a valid public address

A secure tunnel through a public network that connects two ends of a private network

The protocol that delivers status and error messages at the network layer

What is the main challenge with not having a BYOD (Bring Your Own Device) program at a place of employment?

Device types

Firmware Updates

Application Installations

Security Management

Security management is a growing concern for organizations that do not have a BYOD (Bring your Own Device) program in place. As more and more personal mobile devices have made their way into the workplace, making sure that security management is in place is important. A BYOD program can address what is or isn’t allowed regarding personal mobile devices and the organizations data and network use. Without a BYOD program in place, company data may be at risk.

The physical cabling is bad.

ICMP is being blocked by a firewall.

There is no routing information.

“Destination unreachable” means there is no routing information (that is, the local computer or an intermediate router does not know how to get to that IP address).

An active stylus includes electronics within the stylus that enable features, such as menu options via buttons on the stylus, and touch sensitivity. A tablet would need to support an active stylus in order for one to be used with it.

What is the drawback of only testing connections to servers by trying to use them?

It measures the RTT for latency.

It is only dependent on a working link and IP configuration.

It cannot conclude whether a problem is with an application or if it is a network fault.

It uses ICMP to requests to find out the status of hosts on the network.

It cannot conclude whether a problem is with an application or if it is a network fault.

One drawback of connections to servers simply by trying to use them is that there could be some sort of application fault rather than a network fault.

Mid tower case

Slim line case

Full tower case

Mini tower case

Mid tower case

Mid tower cases are used for high-end user PCs. These PCs do require extra devices and adapter cards, but not as many as a server. A tower case is designed to sit vertically on a surface, so that it is taller than it is wide.
