What Is Computer History ? Its Types Of Software?

Computer :

Computer word is Discovered by a English word “Compute” ,which means to “calculation”. it is used for calculation , but now ; it is used in many fields. so , computer is a electronic device which make our work easier and faster. it gave over all Information about instruction . it means , it doesn’t used as a calculator also it is used in many works of technology.

development of computer :

(i) In,1642 Blaise Pascal make world first ” mechanical calculator ” .
(ii) In,1833 British scientist ” Charles Babbage” modified the calculator as a computer. after 40 years hardworking he don’t make this. but he is become a ” father of Modern computer” .

note:

for extra Information
but , to make the computer program . it is do by his student “Ada Augsta Lovelace” . because of this the computer programs name” Ada”.

development of computer is in five steps . due to this reason the computer is divide into five generation.
The five generation of computer is the following :
generation :
first generation :
Is, 1940-52 ; its electronic features : electronic (vacuum tub)
second generation :
Is, 1952-64 ; its electronic features : transistor
third generation :
Is, 1964-71 ; its electronic features : (IC)
forth generation :
Is, 1971- and now ; its electronic features :(LSI)
fifth generation :
Is, optical fiber

computer software :
it is a program of computer in which it have many application software. for example ; word process (which make user for working ).
it have system software , example ; operating system (which make the hardware and others software for using ).

practice computer system is divide into three parts –

(i) system software
(ii) application software
(iii) programming software

system software:
it is used for working computer hardware and computer system. In this operating system, device drivers, dignostic tools, servers, window system ect. system software, server user, application software, and computer hardware accessry device like, cominication, printers, readers
, displays, key- board in between them make for using.

application software :

it is used for user one and more non- computing work . In this application office automation, business software, education software, medical software, database, and computer games are evolve this. business house application software is very big user. but in many man (human) movements application software is used for any forms, for that works, it is used.

program software:

it is used as a simple and more special for using program language. in the tools text editor, compiler, linkers, dangers and many tools are evolve. it is used following functions. it is a specific part of computer software.

system software:

it have operating system and utility program of two types of system software. in this paragraph it has more information about personal computer and operating system.

( OP) – operating system :

operating system is a set of programs, in which between computer hardware all movement of coordination have instruction. for example; operating system, key- board, mouse, micro-phone and pc camera like, input devices is for input to display output at monitor it coordinate , gave instruction to gave information is print and manage the data in memory, instruction and information store by disk. computer for to gave hardware function graphical user interface and for doing work it is need of operating system. operating system are many types. more-ever , it have one type od functions , in them start computer, to gave interface user, to manage the program, manage memory, to schedule job’s , to monitor performance , to gave housekeeping services are evolve.

“it is very high-lighted and very deep introduction of operating system in very easy way and in very easy language”
