A computer is a computer even if it's not connected to anything. But it's usually referred to a "Stand-Alone" device. Additionally, if a computer is NOT part of any particular domain, it's default "domain" (at least for windows) is WORKGROUP.
A computer that is not connected to a network is called a standalone computer.

A network ready device is a device that has the potential to connect to a network, natively it isn't connected to a network, nor is it a network, but with the appropriate configuration and possibly with the addition of components could be connected.
The network is fine, but the computer(s) connected are not, the virus may attempt to hi-jack your internet and prevent you from going to any sites for aid.
A secure computer network is one that not connected to any other network.That may sound simplistic and trite, but it is the truth. In this day and age of super sophisticated decryption algorithms, it is the only way.
'Yellow' is descriptive but does not identify the cable. A description of the ends of the cable would be helpful. However, if your computer is connected to the network then the yellow cable is unnecessary. It may be a management cable or an alternative connection. If your computer is not connected to the network then it is likely that the yellow cable is the rj-45 connection and that you need to install a network card for your computer.
RAM buffering is extra RAM available to your computer which may or may not involve being connected to a network. Server Software is the programs or software that is run on the part of the network that controls the network
It is called a network. If there are computers are connected to each other in the same building or immediate area, then they are considered to be part of a Local Area Network (LAN). If they are connected to other LANs around the world, then they are part of a Wide-Area Network (WAN). A famous WAN many are familiar with is the Internet.

There is a big difference between a personal computer and a mainframe. A personal computer is what you're probably use to; a computer that lets you access the internet, run programs, edit documents, etc. A mainframe, on the other hand, is a much more powerful computer that is usually connected to a network. This kind of computer provides services for other computers on the network. It may store files, manage access to network resources like printers, or perform heavy-duty computational tasks. Since mainframes are usually accessed over a network, they do not usually need a keyboard, mouse, or screen of their own.
This is known as a Network. Depending on the type of network is may also be called a Topology, Beowulf Cluster, Intranet, Internet, LAN, WAN, WLAN, or more.
All computer parts are connected by a large array of cables, however the central component is the motherboard. All components connect to the motherboard. Which gives the parts power and allows them to connect to each other. New components may need drivers to be able to communicate with the computer, these drivers can come with the new hardware, or may need to be downloaded.
There are many reasons why communication may fail. For example (assuming a cabled network), there may be no connected cable, the network card may be damaged, or there may be a communication problem at higher levels. First, check to see whether the computer detects the cable. Then you might try a PING command, to see whether low-level communication works.
