what do you know about Computer Output Units
what do you know about Computer Output Units
Hello my friends we meet together again with another lesson (computer output units).If you see the last lesson it was about (computer input units) and we explain in it all computer input units .Today we will explain every thing about computer output units .Dont worry my friends you will be professional very soon. We start from begging .Lets see our lesson.
Computer Output Units
Today we will start to talk about computer output units .We will talk in details about that in this lesson .Those units responsible for all operations and extraction results, which was implemented by the computer according to the instructions issued by the user .Computer output units is the devices that we connect it to computer and take the output from it like speakers or data like printers or picture like monitor .Computer output units divided to:
- Monitors
- Speakers
- Printers
We will take about every device in details .Lets see
Monitors
Is one of the most important units Computer output so that the screen shows what is entered for computer of letters and numbers and photos etc.. As the screen displays the data previously recorded on the computer.
Speakers
Headphones & speakers are units of data output from the computer. And used in the output of sounds, songs and music. And you can control the degree of high and low sound.
Printers
It is also a unit of output data from the computer. And used in the output data and information (letters - numbers - Photos) printed on the papers.
There is another type of printers called PLOTTERS
PLOTTERS
It is also a unit of output data from the computer. And used in the output graphs and engineering high volumes printed on.
We finish the lesson now .I hope all my friends understand this lesson very well .The next lesson well be about CPU .Thanks my friends....

do you know any thing about computer software
do you know any thing about computer software
Hello again my dear friends in allover the world .We finish explaining computer hardware part. I hope you understand the last part because we will explain the second part .Today we will explain computer software and you will be able to deal with all software on the internet .Lets start..............
Computer Software
Computer programs can be divided into two types of software programs used by computer programs called the system, and programs used by the user and the called application software.
Operation System
Is a system that contains all the commands that enable the computer to function like the start up process and Show on the screen and the use of solid roller (Hard Disk) and floppy disc (floppy disk) to store information. The operating system (operating system) management software such as a word processor, games and a web browser. It receives commands from these programs and passes it to the processor, (processor) and regulates the on-screen display. And takes the results of the wizard, and then sends it to the store on the hard disc or for printing on the typewriter. Drivers are always present in the computer and begin to work automatically when it runs. The computer is turned on the engine system for both cars can not do without.
The most famous operation system:
- Dos
- Windows XP 98
- Windows XP 2000
- Windows XP NT
- Windows 7
- Windows Vista
- Linux
- Unix
- Mac
Now we finish the lesson .Next lesson we will explain different types of software .Please if you want to ask me please feel free.

Do you know the difference between software application types
Do you know the difference between software application types
Hello my friends, last lesson we explain the first part of computer software and we explain operation systems. Today will explain the second part of software .It will be about software application systems and its types and function of every application .Lets start now
Software application
There are five types of software application like:
- System Software
- Commercial Ware
- Shareware
- Free Ware
- Public Ware
We will explain each type in details
System Software
Programs are present on the computer and previously stored on the disc hard when you buy it. When you use the computer for the first time may be needed to enter some information to composition. This is like that we define the type of computer printer connected to it, and if there is a link to the Internet and the like. Some tasks can be added to the system software whenever the need arises. For example, if you change the printer, we need to download additional software for a computer to deal with the new printer.
Commercial Ware
Programs are offered for sale commercial programs, as a group office programs (Microsoft office). For example, Commercial programs are available for thousands of uses, such as drawing, accounting and business management and editing movies. And commercial software is often licensed to the user rather than just selling the customary way, with surrounding different conditions associated with their use, as described earlier.
Shareware
Many programmers and hobbyists no programs that are available for free. And distribution of these programs may be via the Internet or distributed with cylinder magazines. These programs are usually available for some time before buying. Pay for these programs depend on trust and honor. If the user wants to continue to use the software after the trial period, he must pay fees to the author
Free Ware
Be similar to programs without participation fees are distributed free of charge and is not expected to pay for them and some authors are responsible for the quality of the program. As is the case in the programs available, they also come under some conditions developers may distribute copies initial free so that users feel the usefulness of the program. And often keeps the authors of these programs with all legal rights to their programs. May not be copied or distributed to these programs.
Public Ware
These programs are available for public use it is available for free and can be copied and modified, there is no fee to use it.
Now we finish the lesson .Next lesson will be about the difference between programs and application .To be continued
