I would like to share some information about my early journey in software and its about
INPUT AND OUTPUT DEVICES
my name is HASHED MOQBEL ABDULLAH FAREA AL-NAEEM

WELL, I'm still a child as far as software is concerned
The comparison between INPUT and OUTPT DEVICES and discuss the process involved in putting data into the computer.
What INPUT and OUTPUT mean?
INPUT:
Devices which transfer data, program or signal into a computer system are called INPUT DEVICES . These devices are used to give raw data (input) to the computer to perform the specific tasks . Firstly,the data ,progress or signals are fed into the input devices in a suitable form,and are then converted by the device into electrical signals from human -readable format that are transmitted to the central processing unit of the computer.THE PICTURE shows a few of the important INPUT Devices which are used in a computer .
OUTPUT:
OUTPUT Devices are used to get the final result from the computer.
Firstly ,output is displayed on the monitor.Then we can printout these outputs on a paper with the help of a printer . The purpose of the output devices is to translate data and information from electrical impulses to human-readable format
What is the process of entering data into a computer?
DATA PROCESSING is broadly the collection and manipulation of items of data to produce meaningful information ,in this sense it can be considered a subset of information processing, the change processing of information in any manner detectable by an observer ,the term is often used more specifically in the context of a business or other organization to refer to the class of commercial data processing applications ,data
processing may involve various processes including validation ensuring that supply data is clean ,correct and useful ,sorting ,arranging item's in some sequence and or in different state ,s
summation reducing detailed data to it's main points aggregation combining multiple pieces of data ,analysis the collection organization ,analysis interpretation and presentation of data reporting list detail or summary date or computed information classification separates data into various categories although widespread use of the term data processing dates only from the 1950s data processing functions have been performed manually for millennia for example bookkeeping involves function such as posting transactions and producing reports like the balance sheet and the cash flow statement completely ,manual methods were augmented by the application of mechanical or electronic calculators.
Here create animated video to discuss the process involved in getting data processing cycle into the computer

Types of computers that comes in different sizes,larger to small and etc.
I am going to tell you that there are four types of computers
01-MICROCOMPUTER (PERSONAL COMPUTER )
It can be obviously seen that these Alva histories and usage etc this explanation about microcomputer became the most type of computer in the late 20th century .These computers include:
Desktop computers :
A case put under or an a desk. the display maybe optional , depending on use.The case size may vary ,depending on the required expansion slots.very small computers of this kind maybe integrated into the monitor .
Rackmount computer
The cases of these computer fit into 19-inch racks ,and maybe space-optimized and very flat .A dedicated display, keyboard ,and mouse may not exist, but a KVM switch or built -in remote control (via LAN or other means) can be used to gain console access
In-car computers (carputer)
Built into automobiles-for entertainment ,navigation ,etc.
game consoles-
fixed computers built specifically for entertainment purposes such as (video game)
MICROCOMPTER MODELS .
01-DESKTOP
02-LAPTOP
03-NOTEBOOK
04-SUB-NOTEBOOK
05-PALMTOP
ADVANTAGES
*SMALL SIZE
*LOW COST
*PORTABILITY
*LOW COMPUTER POWER
*COMMONLY USED FOR PERSONAL APPLICATION
DISADVANTAGES
*LOW PROCESSING SPEED
USES OF MICROCOMPUTERS
*WORD PROCESSING *PRINTING
*HOME ENTERTAINMENT *SURFING THE INTERNET
* HOME BANKING *ETC
MINICOMPUTERB
Medium sized computer also called the minis
*e.g.IBM36,HP9000,etc.
Computer power lies between microcomputer and mainframe computer
characteristics
*EXPENSIVE THAN PCs
*BIGGER SIZE THAN PCs
*MULTI -USER
*DIFFICULT TO USE
*MORE COMPUTING POWER THEN PCs
USED BY:
*MEDIUM SIZE BUSINESS ORGANIZATION
*COLLEGES
*LIBRARIES AND BANK
*USES OF MINICOMPUTER
*CONTROL of automated teller machine (ATMs)
*Hospital patients for supermarket
*INVENTORY claims processing
*small bank counting and customer details tracking
MAINFRAME COMPUTER:
KNOWN AS ENTERPRICE SERVERS
occupies entire rooms or floors
used for centralized computing
serve distributed users and small services in a computing network
LARGE, FAST AND EXPENSIVE COMPUTER
COST MILLIONS OF DOLLAR
e.g. IBM3091, ETC
AREA WHERE MAINFRAME ARE USED:
*airline reservation
*big bank with hundreds of branches located all over the world
*big universities with thousands of enrollment
*space vehicle control
some mainframe are designed to be extremely fast and called super computer .it is used for space launching, monitoring and controlling
