A computer system can be divided into 5 components:
In studying Computer Systems' Architecture, only the first 3 of these are of direct interest.
HardwareIn general, digital computers (the only type considered in this course) represent values as patterns of "off" and "on" signals. Each value requires a different pattern (or, at least, a pattern which is different from any other value of the same type). Different types of values generally are represented using different "encoding schemes". An "encoding scheme" specifies how many "off" and "on" signals are required for each value, and provides a unique pattern of signals for each possible value.
Data vs. InformationTwo terms common in any discussion of computer systems are "data" and "information". The difference in meaning between these two terms is based on the concept that "information" is "data" which has "meaning" to someone (or something) outside of the computer system."Information" is "data" which has meaning. The most common task of a computer system (especially when the input source and the output destination are the same) is to transform data into information. In fact, this is sometimes used as the basis for alternative definitions of a computer system .
The concept of "meaning" can be difficult. Generally, we think of "meaning" as implying that something with intelligence exists for which the "data" has meaning. When the output of a computer system is the automated control of some other system (as in CAD, Computer Aided Manufacturing), we end up debating, the unresolved question of what is meant by "intelligence".
1. The IPO(S) ModelA computer system can be thought of as a collection of components which together are capable of 3 operations: Input, Processing, and Output. A fourth operation, Storage, is also required for practical computer systems.Note that the IPO(S), Input-Process-Output(-Storage), model is applied to at least two different areas:
Power or energy sources required to enable operation of the computer system are not "inputs".
Processing:A computer system must include the ability to change or "transform" data which has been input. These "transformations" typically include (but are not limited to)For the purposes of this course memory (or "storage") will be considered to be an essential element of any computer system.

Computer hardware is the components that make up a computer. Computer architecture is the model used to combine the Hardware into a working unit.
It is fairly simple to find the router's model via the computer. Just right click on 'computer,' and go into Device Manager. From there, simply select the router and click 'properties.' This will display the router's model and any other pertinent information.
