Hardware and Software HW

1. It stores and represents information by using two digits, 0 and 1. It is extremely simple, and can represent

multiple things, such as photos, colors, text, and music.

2. Binary is much simpler, less ambiguous, and perfect copies of the binary can be produced. Analog signals can

consistently change in volume, and noise can impact the signals.

. !rocessors run software and applications. "hey decode information, so that it can be understood by the

 processor. "hey execute information, doing what the commands state and running the software. "hey store the

information for future use, and fetch information.

#. $ain memory contains data being used by the computer. It allows for the current programs and applications to

 be loaded and used.

%. $ain memory is needed, because without it, the data and programs currently being used by the computer coul

not be loaded.

&. 'econdary memory is used for storing data and programs on the long term. It can be in the computer, or can be

external storage, such as ()s or flash drives.

*. $ain memory contains the data and programs currently being used by the computer. $ain memory is lost whe

the computer is turned off. 'econdary memory is for storage, and only erased if the user deletes it.

+. "he language used for programming that the micro processor understands and is able to decode and execute.

. -o, because different processors have different machine languages that they understand.

10. $emory is stored in bits, which are stored in bytes, which can be stored in megabytes, etc. Bits are small unit

information that contains memory and information for programs, systems, applications, etc.

11. $achine language is written as numbers, and is much simpler than human language. It is less flexible and mor

constricted than human language.

12. ardware is the physical components that ma/e up the computer, and the software is the collection of program

applications, etc. "he software tells the hardware what to do and how to operate. "he hardware is useless

without the software to instruct it, and the software is useless without the hardware to carry out the programs.

1. !rogramming language can use words, while machine language only has numbers as commands. igh level

 programming is also used for more complex operations.
