The cuurent technologies of computers in the world markets

According to change in time and technology there is a large variation among the past,present and future as well. We should know what is inside the computer? When the service technician was installing somethings for you may be peeked. A computer is a large threatening machine when you look inside the CPU of computer at first time in your life. But when you see a parts of the computer once you know about the different parts of that make up complete computer it gets a lot easier to know. At present day computer have at least eight components but the advance computer have more then eight components. What are the main components and how they are use for? We are started with beginning to know you.
The Power Supply: The power supply is the process of supplying electricity to all of the components in your computer. It is positioned in one of the corners of the computer in a rectangular box. To find the power of the computer you should look where the power cable plugs the computer and then you find the power supply. Power supplies are calculated in Wattage and come 50 watt increments(500 watt,550,600, etc)
Motherboard: motherboard is the main components of the computer system. All the components are connected into the main components called motherboard. It is not said to be a brain of the computer system. But it holds the brain and helps it act together with all the other components of the machine.
Important components of the computer CPU: Central Processing Unit is know as the important components of the computer system. Because it is know as the brain of the computer system and nothing is going to happen without it. All the computer calculation, processing as well as performed by a computer are carried out inside its CPU. It is responsible for activating and controlling the operation of other units or the system. It is measured in gigahertz(Ghz) and ti is faster then 3.8Ghz at present.
Random Access Memory: Random Access Memory is used as temporary working storage for the computer.RAM have different types with their speed, but it should match with your motherboard. It can work properly. If you have more RAM in your computer it works as better as those computer who have less RAM in computer hardware.
Hard Drive: It is a storage device for every things.In the hard drive operating system(Windows XP, etc) are includes,games,and different types of software etc are also available. The capacity of the hard drive is being continuously increasing according to change in time and technology. In the interval of few years its capacity have gone from around 20 MB to over 500 GB and more. Because of storing device hard drive can store a lot of information, games, pictures, videos, application,and more.
Cooling fans: It is the main part of the computer system. Cooling fans is connected with the CPU to cool down the heating of components of the computer. It helps to cool down the heat generated by other components, such as power supply, the CPU, and some high-end videos cards. Cooling fans puts computer overheats and breaks, while most of the noise you hear coming from a computer can be credited to the cooling fans,it is the parts of computer.
The seventh and final components is the combination of different devices. They are; Cd-rom,DVD drives, Floppy disk and backup devices such as external hard drive.

What do you mean by operating systems of computers technology?

What is an operating system?

An operating system is a set of programs that manages the hardware and resources for the computer system. It also handles files, programs and deals with other requests. It controls over the Input and output devices. It plays the role of an interface between the users and the computer for interaction between them. The computer is use less without operating system. The example of operating system are: Ms-DOS, Windows 95/98/xp, UNIX, LINUX etc. A set of programs that controls the entire operation of the computer such as handling Input/Output operation, user request, interrupts etc is known as operating system. Operating system manages the resources of a computer system and schedules its operation. It is a master supervisory program which provides a friendly interface for the user to interact with the computer and its peripherals and different application software as well as an environment for program to execute.
Operating System(OS) is a computer program (system Software) that act as an intermediate between the user and computer hardware. This is the first software we see when we turn on the computer and again the last software we see when the computer is turned off. As computer consists of various resources (or parts) like Memory,CPU, Disks etc. it's very difficult for the user of computer to understand how to operate them directly. So, OS becomes the interpreter between the computer hardware and user. It interprets the command of users to the hardware and presents the output to user in a suitable format produced bu hardware. For example, if we want to save our Bio-Data into the floppy disk, then we don't know "how to write" or "where to write" inside the floppy disk, but our duty is simple to give command to the operating system (i.e. Save into floppy) and now it's the job of operating system to tell the floppy drive what to do exactly. In short,OS acts as an interface and hides the every details of working principal of computer from the user, thus operating system can be regarded as resources manager.
Also operating System provides user a high level abstraction. Without knowing much more internal details of any devices the user can operate them through Operating system.

What are the Functions of an Operating System?
The main functions of an operating system are as follows:

• Memory Management: The basic function of an operating system is to manages the memory available to application programs in the computer. The operating system determine the amount of memory required for the programs instructions and for data. It allocates the amount of memory required and loads the program into RAM(Read Access memory).
• File Input/Output Management: One of the most important functions of an operating system is to manage the file input and the output. It manages the files stored on hard disk and other storage devices. It also provides the facilities such as to create the files, opening the files for read and writing trans fore the data and so on.
• Device Input/Output Management: The another important function on an operating system is to manage the input and output devices.It plays a role of an interpreter for various devices and language. It uses the specials program known as device drivers to translate the input/output request into commands to specified the hardware devices.
• CPU management: The operating system handles the processing jobs of the CPU. It helps the CPU to schedule its activities to meet the demand of the users and various parts of the CPU and the computer itself. The CPU gets the jobs from the keyboard or a storage medium , puts it into the memory , process the input and passes the results to the output devices.
• Operating in Batch Mode: Most of the operating system allows for operating in batch mode. In batch mode operating system user can instruct the operating system to execute a number of program one after another.
  

What are the main basic types of Operating System?
Operating System can be classified into following categories:

• Single-user operating system: In the operating system the single-user operating system can work at a time. I mean this operating system provides an environment where single-user can work at a time. It provides all the necessary resources to the user. The example of single-user operating system are Ms-Dos,Windows 95,98,XP,etc.
• Multi-user operating System: This is operating system allows more than one user to share and access the data and programs at a time. This operating system provides the total time into a number of time slices and schedule the task one after another in a given priority. The example of multi-user operating system are, UNIX,LINUX,Windows NT.
• Multi-tasking operating system: This operating system allows a PC(personal computer) to perform more than one task at a time.There are different types of multi-tasking operating system. Such as context switching, co-operative multi-tasking, Time-slice multi-tasking.
• Multi-processing operating system: In the operating system more than one processor are linked together in co-ordinate way. This processor share main memory and input/output devices.These processors can execute(run) different independent programs simultaneously. They can also execute the part of the same program. The example of multi-processing operating system are UNIX,LINUX,MVS etc.
• Real-time Operating System: This operating system is as online operating system that responds to input immediately. This operating system is designed for controlling and monitoring the external activities with time constrains. It is useful for controlling the external activities such as load shedding, traffic lights etc. The example of real time operating system are ccp, Bso,/RTOS.

How many types of software are there and diffination of them?

What do you mean by software?
Computer is a programmable machine that helps to process the undefined thing by using computer software. A software is a set of computer programs that we can operate in the computer. Generally, software is classified into two classes , they are , system software and application of software.They are explain below:

System Software:
System software is the software that is used to control and co-ordinate the hardware and the software. It manages the resources, memory, files, task etc.
Mainly there are following system of software:

• Language translator (processors) : The language translator are used to translate or convert the source code into the machine codes source code are written assembly or high level language. The example of language translator are, Assembler,interpreter, and compiler.
• Simulator: Simulator is the system software that is used to simulate the execution of the programs of the other computer. This types of software is used to learn the subjects of technology nature.
• Emulator: Emulator is a software that is used to mimics the function of other programs,computer,modem,printer etc. It is also used for converting the program written in one language into other language.
• Utility Software: It is a software that is related with the utilities of the computer system. Generally it is used in file management, memory management, disks repairing, virus scanning etc. The example of utility software are: Norton Utilities, PC Tools, Scan disk, defragmenter etc.
  

Application Software: It is a software that is used for specific purposes. It is needed for the user to run the program in the computer. Generally, this software are developed by using the high level language. The example of application software are: Word processing, Spread sheet, Data based management System(DBMS),Graphics etc.
Application software are mainly classified into two classes they are:

1. Packaged Software
2. Tailored Software

Packaged Software: It is readymade and advance and standered software use for sprcific purposes. It is developed in the big warehouse by the group of export software developers or programmes. For example the Microsoft co-operation,USA developeds the different types of packaged software. Such as microsoft offices packages, microsoft visual basis etc. This software are equppied with all the essential tools and technology to enhance(to expand) user poductivity. Examples of packaged software are word processing, Data base Management System(DBMS), Graphics, Animation softwares etc.

Tailored Software: Tailored software is the special types of software that is design or developed as a requirements of individuals to organization.It is a smalls moftware that is developed in high level language for specific small purpose, For example: Accounting Software, Payrool Software, Departments store Software, Software for Bank etc are the tailored software.

These software are developed for solving the specific problems of specific users or organization. Gernarlly, these software are developed using the high level languagesuch as COBOL,C.C++,Java etc.

What do you mean by computer hardwares and there types with example?

Computer is a devices made by the hardware or physical parts of the components which is made by the human beings. The physical parts of the computer is known as computer hardware. Hardware are the external and internal parts of the computer system. It is man made components of the computer as well as other man made components. It is a physical artifacts of the technology. Artifacts means the physical components or an objects that is produced by the human crafts, specially a tool, weapon of a historical interest. In the computer system CPU is the main hardware. In the CPU, Mother board, keyboard, mouse are the main parts of the computer hardware system. Hard drive is the storage of software of a skill or informational.

Computer hardware is the physical pats of the computer system. It is opposite to a software because software can be frequently changed,modified or erased on a computer but hardware is not frequently changed or modified like a software. So that hardware is opposite to the computer software. There are many ttypes of hardware they are:

Motherboard: It is the main processor of the computer hardware system. It is the central or primary circuit board making of the computer.It is also known as the main board, logic board system board.
CPU(Central processing Unit): it is also the main components of the computer hardware. Because, it interprets the instructions and process them in the computer programs.
RAM(Read Access Memory): Read access Memory is a hardware that con be stored the program to accesses the min the computer. It help to displaying and manipulating data where it is used.
Hard disk : it is also considered as a main parts of the computer system. Because it helps to stored data for future processing. It can stored data for permanently. It is said to be non-volatile .

What is computer? And there functions with example.

A computer is a electronic device that calculate the mathematical operation within the second. It is a device that receive the data from input devices and process them by processor and gives the output from out put devices. A computer consists of main processing unit called central processing unit(CPU) or microprocessor, input devices(normally keyboard,mouses), output devices(normally monitor, printer),main memory(RAM) and auxiliary memory(hard disk, floppy disk). There are five types of computer generation up to now. the first generation computer had big in size com pair the other generation computer. The computer had been discovered in the 20 century. At the first time in the history the computer had been discovered. The size of the computer was large in size. That covers a whole room. The users of computer was more then hundred. The main processor of that computer had been redistributed more then hundred terminators. The computer dose not have the permanent storage device. Now the technology has been totally modernized by the scientists. The present computers has small in size compare to the previous generation computer. Todays, the computer like Laptop, palmtop, etc. are available in the market. In the first generations computer consumed more electricity and produced more heat. But the presents computer have more reliable then the first generation computer. Personal Computer have a high integration power then the previous generation computer. It is a programmable machine because it process the programs in the computer. It only understand programmable language. In the present day computer has been develop in a good manner that it understand human language and think as well. Before the computer only understand machine language because the letter are write in the human understandable language are not understand by the computer. Computer is derived from Latin word "computare" which mean 'calculate'. Computer are use in wide and variety of fields e.g. homes, school, college, offices, industries, etc.
