Compiler and Computer Labs
We will learn C++ using the Orwell Dev-C++ compiler under Windows
It is free compiler and you can download from
http://sourceforge.net/projects/orwelldevcpp/
Every week you should write a few programs yourself in the BIM lab (and more in your free time).
In the BIM Computer Labs your programs will be deleted when the computer restarted. So you need to save them on a flash drive or on the internet.
If you have a Smartphone, you can download and install
CppDroid from PlayStore. Then you can check your C++
program at anywhere you want.

The Computer
A computer is a machine that manipulates data according to
a set of instructions.
The first computers were developed in 1940–1945, they were very large in size!
Modern computers are based on integrated circuits making them very fast and small in size.

Parts of a Digital Computer
A computer can be divided into two main parts:
Hardware and Software.
Hardware (=Donanım)
See http://en.wikipedia.org/wiki/Hardware
Hardware is the electronic and
mechanical parts of the computer.
- Storage Units
- Input Units
- Output Units
- Process Units

Parts of a Digital Computer
Storage Units
These are used in both input and output of data:
HDD (“Hard Disk Drive”) SSD(“Solid State Disk”)
– high capacity – moderately high capacity
– relatively cheap – very expensive
– slow – very very fast
RAM (“Random Access Memory”)
– low capacity, expensive, but very fast.
Others:
Flash memory (memory cards, USB flash drives), CD, DVD...

HDD (“Hard Disk Drive”)
11
A hard disk drive is a device for storing and retrieving digital
information, primarily computer data.
It consists of one or more rigid (hence "hard") rapidly
rotating discs (platters) coated with magnetic material, and
with magnetic heads arranged to write data to the surfaces
and read it from them

RAM (“Random Access Memory”)
12
Random-Access Memory (RAM)
device allows stored data to be
accessed in very nearly the same
amount of time for any storage
location, so data can be accessed
quickly in any random order.
SDR-RAM DDR-RAM
DDR II-RAM
DDR III-RAM

Flash memory (memory cards, USB flash
drives), CD, DVD...
A USB flash drive is a data storage device that includes flash memory with an integrated Universal Serial Bus (USB) interface.
Secure Digital or (SD) is a non-volatile memory card format for use in portable devices.
The Compact Disc, or CD for short, is an optical disc used to store digital data.

Parts of a Digital Computer
Data is input from a keyboard(3) which is again stored in RAM(4).
The CPU operates on the program and data in RAM(5) and
outputs results to the HDD(6) as well as the monitor(7).
This is all controlled by the CPU requiring only basic
data flow instructions from the programmer.

Parts of a Digital Computer
Software (=Yazılım)
See http://en.wikipedia.org/wiki/Software
Software consists of programs loaded from storage units.
The programs execute on the computer hardware forming,
for example,
Operating System (OS)
Compilers
Application Programs

Operating System (OS)
The OS is a program written to interface between the computer and it’s user. All other software runs under the OS.
Examples are:
Miscrosoft Windows (XP, Vista, 7,8)
Linux (e.g. Redhat, Ubuntu, Pardus)
Mac OS X.

Compilers
Many programming languages require a
compiler to translate the statements of
program written in a high level language into
a low level language (machine code).
In this course we will use Dev C++ compiler
to obtain the executable forms of our
programs.
Ms. Visual Studio and Borland C++ can also
be used for compiling our C++ programs

Application Programs
These are (usually compiled) programs written to perform a specific task.
Examples are:
Microsoft Word
AutoCAD,
SolidWorks
Catia
ANSYS

An Engineer and Computers
Engineers use computers extensively
to produce and analyze designs;
to simulate and test how a machine, structure, or system operates;
to generate specifications for parts;
to monitor the quality of products; and
to control the efficiency of processes
