What are the elements of a computer system? |
Hardware, CPU , Main memory, Secondary storage, Input/output devices, software. |
|
|
What are some categories of computers? |
Mainframe computers, midsize computers, and microcomputers(personal computers) |
|
|
What is the hardware of a computer? |
CPU, Main memory: RAM, Input/output devices, Secondary storage. |
|
|
What is the central processing unit? |
This is the brain of the computer. It's the most expensive piece of hardware that carries out arithmetic and logical operations. |
|
|
What is random access memory? |
This is directly connected to the CPU. All programs must be loaded into main memory before executed. All data must be brought into the main memory before it's manipulated. When the computer power is turned off, everything in memory is lost. |
|
|
What is the main memory? |
It's the ordered sequence of memory cells. |
|
|
Each cell of main memory has what? |
Each cell has a unique location in main memory. Each cell contains programming instruction or data. |
|
|
What are the two popular programming methodologies? |
-Structured -Object Oriented. |
|
|
Structured design is what? |
Dividing a problem into smaller sub problems. |
|
|
What is structured programming? |
It means to implement a structured design. |
|
|
The structured design is also called what? |
1.) Top down(bottom up) design. 2.) Stepwise refinement. 3.) Modular programming. |
|
|
Objected oriented design is what? |
It identifies components called objects. It determines how objects interact with each other. Object oriented design specifies relevant data and possible operations to be performed on that data. |
|
|
An object combines data and operations on data into what? |
A single unit. |
|
|
If you want to learn OOD, what must you learn to do? |
You must learn how to represent data in computer memory, how to manipulate data, and how to implement operations. |
|
|
C++ evolved from what? |
The C language. |
|
|
C++ was designed by who? |
Bjarne Stroustrup at Bell Laboratories in 1980. |
|
|
True or false? The primary storage is volatile. |
True. |
|
|
True or false, the secondary storage is volatile. |
False, permanent. |
|
|
The compiler does what? |
It translates high level language into machine code. |
|
|
Object Oriented design is what? |
The program is a collection of interacting objects. |
