Data type:
is a classification of the type of data that a variableor objectcan hold in computer programming. Data types are an important factor in virtually all computer programming languages, including C#, C++, JavaScript, and Visual Basic.
Examples of data types
Boolean(e.g., True or False)
Character(e.g., a)
Date (e.g., 03/01/2016)
Floating-point number(e.g., 1.234)
Integer(e.g., 1234)
String(e.g., abcd)

First Generation Computers
(1940-1956) yThe first computers used vacuum tubes(a sealed glass tube containing a near-vacuum which allows the free passage of electric current.)for circuitry and magnetic drumsformemory. yThey were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat. yExample: Electronic Numerical Integrator andComputer (ENIAC) .

First Generation Computers
Advantages :
It was only electronic device
Disadvantages :
large in sizeVacuum tubes burn frequently
Maintenance problems
13Ass. Lec. Tamara A. Anai
SecondGeneration Computers
(1956-1963) Transistors replaced vacuum tubes and ushered in the second generation of computers. Second-generation computers moved from binarymachine language to symbolic. High-level programming languageswere also being developed at this time, such as early versions ofCOBOL andFORTRAN.Example : IBM 1401

(1964-1971)The development of theIntegrated Circuit(IC).
Allowed the device to run many differentapplicationsat one time.Example: IBM System/360
Advantages :
ICs are very small in size
Improved performance
Production cost cheap

FourthGeneration Computers
(1971-present) Themicroprocessorbrought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. From thecentral processing unitand memory to input/output controlson a single chip. . Fourth generation computers also saw the development ofGUIs, themouseand otherdevices.Example: Macintosh 128k

Features of a Computer
High speed, accuracy large storage capacity, high reliability and versatility are some of the important features of computers.
SPEED: In general, no human being can compete to solving the complex computation, faster than computer.
ACCURACY: Since Computer is programmed, so what ever input we give it gives result with accurately. STORAGE: Computer can store mass storage of data with appropriate format. POWER OF REMEMBERING: It can remember data for us. Computer can work for hours without any break and creating error. We can use computer to perform completely different type of work at the same time. 19Dentistry College -University of Tikrit

Types of Computers
1. Analog Computers
Analog computers are used to process continuous data. Analog computers represent variables by physical quantities. Thus any computer which solve problem by translating physical conditions such as temperature, pressure, or voltage into related mechanical or electrical related circuits as an analog for the physical phenomenonbeing investigated in general it is a computer which uses an analog quantity and produces analog values as output. Analog computers are very much speedy. They produce their results very fast. But their results are approximately correct. All the analog computers are special purpose computers.Dentistry College -University of Tikrit

Digital computer represents physical quantities with the help of digits or numbers. These numbers are used to perform Arithmetic calculations and also make logical decision to reach a conclusion, depending on, the data they receive from the user.Ass. Lec. Tamara A. Anai25
3. Hybrid Computers
Various specifically designed computers are with both digital and analog characteristics combining the advantages of analog and digital computers when working as a system. Hybrid computers are being used extensively in process control system where it is necessary to have a close representation with the physical world.Ass. Lec. Tamara A. Anai26

Computer Classification
Personal computer(PCs): a small, single-user computer based on a microprocessor. In addition to the microprocessor, a personal computer has a keyboard for entering data, a monitor for displaying information, and a storage device for saving data. Workstation: a powerful, single-user computer. A workstation is like a personal computer, but it has a more powerful microprocessor and a higher-quality monitor. 28Ass. Lec. Tamara A. Anai
Computer Classification
Minicomputer: multi-user computer capable of
supporting from 10 to hundreds of users simultaneously. Mainframe: powerful multi-user computer capable of supporting many hundreds or thousands of users simultaneously. Supercomputer: an extremely fast computer that can perform hundreds of millions of instructions per second. 29Ass. Lec. Tamara A. Anai
