Answer:
System software is software designed to operate the computer hardware and to provide a platform for running application software. There are two types of system software: Operating System Software – Manages the computer hardware and software. Utility Software - Tools designed to help the user manage the computer system.
There are two things that make up a computer system - the physical parts of the machine (the hardware) and the programs that make them run (the software). Without either of these, the device would simply not be a computer.
The most important piece of hardware in a computer is the CPU (Central Processing Unit) which acts as the brain of the computer. The other core pieces of a computer are the power supply, motherboard (which sends signals around the computer) and the computer case. Technically, all other parts of a computer are referred to as peripheral devices - that is devices that can be connected to a computer but is not part of the core architecture.
The answer is a Mesh topology. This method connects every device to each other device in the network. A wired full-mesh topology is not as common as it is impractical and highly expensive. A partial mesh topology offers redundancy if one of the connections goes down and usually uses a connecting medium such as a router to eliminate cables and expensive PCI NIC's.

A PCM system consists of a PCM encoder (transmitter) and a PCM decoder (receiver). The essential operations in the PCM transmitter are sampling, quantizing and encoding. All the operations are usually performed in the same circuit called as analog-to digital convert Early electrical communications started to sample signals in order to multiplex samples from multiple telegraphy sources and to convey them over a single telegraph cable. The American inventor Moses G. Farmer conveyed telegraph time-division multiplexing (TDM) as early as 1853. Electrical engineer W. M. Miner, in 1903, used an electro-mechanical commutator for time-division multiplexing multiple telegraph signals; he also applied this technology to telephony.
<span>The statement that the order or sequence of rules in a Prolog program is usually critical. is false. </span>Prolog programs are simply
knowledge bases. And knowledge bases are collections of facts and rules which describe some collection of relationships that we find interesting.
