Computer network LAN

In general, a computer network can be divided into three types, namely LAN (Local Area Network), MAN (Metropolitan Area Network), and the latter is a WAN (Wide Area Network). But we shall see this time is a computer network that has the smallest range among three, namely LAN (Local Area Network). Computer Network LAN is a computer network that consists of a few things to computers that have a limited range in a relatively narrow area. LAN network example that we often encounter is the LAN network in the cafe, library, Lab School, and others. LAN computer networks in general are mutually network used to connect multiple computers into a single entity in order to share data and resources such as a printer, scanner, modem at the same time. Network LAN LAN is also divided into traditional and modern LAN. The most fundamental difference in this network is in terms of speed of operation. Traditional LAN networks have a level of operating speeds range from 10 up to 100 Mbps (megabytes / second). While modern LAN network have an average speed that far surpasses it, which can reach speeds of up to hundreds of Mbps.

How to Make a Computer Network LAN

To be able to connect between computers, usually using a LAN network cable media. If the LAN network only consists of two computers we will only need a UTP cable by the connector at both ends.Connector we can get in a computer store, while a good idea to adjust the cable length distance between the location of one computer to another computer. Meanwhile, if we connect the computer to be in excess of two, then we will need an additional device that is often called Switch or HUB. And to make computers can communicate with each other.Then each computer must be given the IP address of each. To verify whether the LAN computer networking is successful, then we must examine one per satau to the entire computer. LAN computer network created not without purpose, but as a medium for the exchange of data / information, using resources at the same time within a computer network, as well as communication between computer users, and share the Internet connection that can be done easily and quickly. So what can we learn this time, a short, compact, and definitely not? Hopefully this brief discourse can make us understand more about the computer network LAN. For added insight, see also the information on the computer network equipment and functions, may be useful.

Getting in on the definition of Computer Operating Systems

Almost every computer user has to know what is meant by the operating system (operating system or OS). But some are already old 'friends' with the computer but do not understand exactly what it is meant by the operating system.The operating system in English is the operating system or abbreviated to OS, is a kind of software (software) which has the task to carry out the management and control of the hardware and basic operating system.Included are running software applications such as multimedia programs, data processing programs, word processing programs, and so on which can facilitate the work of man.Computer operating system software is contained on the first layer located on the computer hardware and the operating system will automatically run instantly when the computer is turned on. Whereas other software will be able to walk after the existing operating system on the computer has been running.

Definition Definition Operating System On Your Computer

And in general the operating system is a system that is tasked to serve these softwares. The common core services may include memory management, access to the disk, task scheduling, and others who generally have to dilakuka solely by software.

But with the computer's operating system on each software do not need to do complicated things such as resolved by the operating system. To perform tasks common core and is carried by a code that is often referred to as "Karnel" a computer's operating system.

One other functions of the operating system is a software layer anatara liaison with the hardware layer. In addition, a variety of important commands contained on the computer have also been performed by the operating system, as well as ensuring a variety of multifunction applications can continue to run smoothly and without a hitch despite the run concurrently.

If there are several applications that can run simultaneously, then the task of the next operating system is set up an appropriate schedule, so that the whole process memunginkan contained on the computer can run a considerable time without disturbing other devices.

As an example of the operating system on the computer are:

  - Windows 7
  - MacOS
  - Windows Vista
  - Ubuntu


How? Through this brief description has definitely made kitalebih know about the operating system on the computer instead? It is decomposed here is simply understanding the operating system on the computer in the course outline.

Types of Computer Based Data Processed

This type of computer that exist during this time are extremely diverse. Both in terms of design, features and technology. Modification of computer devices also started to appear. For example, it has been widely spread practical computer device is a laptop, notebook, netbook, and so on. However, if the review of the data processed, the computer simply be divided into three parts. Want to know what these parts? Check out his review below.

a. Analog computer
Analog computer or in English is called analog computer is a computer that operates in parallel / analog to process programs and data that are continuous, quantitative data in the form (temperature, air pressure, electrical current, etc.). Computers of this type are often used in the control of chemical-based industries, oil refineries, power plants and parts of the hospital which is to monitor the patient's heart rate.

The advantages of analog computer:

    - Fast data processing
    - Can automatically controlling industrial processes
    - The results of accurate measurement data
    - Known as a computer with special-purpose label
    - Can do a representation of the quantity that will be or have been processed with a range of values ​​which have been adapted to the value of the amount
Disadvantages of analog computers:

    - While doing sometimes less precise processing
    - Unstructured and lacking multifunction thus limited to a specific user
    - Can only be used to solve a specific problem (specifically)
    - Less accurate to process data or programs that in fact is the numbers
    - Has components that pretty much so inefficient

b. Digital computer
Digital computer or digital computer is a computer that operates based on the count. As its main function is to arithmetic operations, this kind of computer has a variable form of numbers. Settlement problems in digital computers are using a quantitative process and process logic or arithmetic. Computer digital type is typically used for business applications as well as use in terms of technique.
The advantages of digital computer:
     - The accuracy of the process data is greater than the analog computer
     - Can perform the activity logic operation by comparing two values and determine the outcome
     - Can perform data storage
     - Can do editing the data that has been entered
     - The data generated from this computer can contain letters, numbers, graphs and figures

 c. Hybrid computer
Computers hybrid or hybrid computer is a computer that operates quantitatively and qualitatively. This hybrid type of computer is a form of a combination of analog and digital computers. This computer works qualitatively and quantitatively because basically carries two roles at once represented from each of the analog and digital computer functions.
The advantages of the hybrid computer:
     - Process data faster than a digital computer
     - More precisely in the processing of data than analog computer

Getting to know some of the components Computer

In a sense, the computer is a series, thousands, even millions of connected components and can cooperate with each other. So, what are the component in question? a series of these components would have not become alien to us sikarang. In general, pda computer components can be divided into three categories, namely input, process and output.

The components are included in the category of component inputs (input) is as follows:
Mouse and keyboard
The keyboard is a tool that serves to entering the command in the form of characters, figures and text. While the mouse is a device that serves to move the object and give commands into a computer.
Now it has provided various forms, types, and sizes of the two tools, but in general the same function that is only a tool to enter a command.
Scanner is a device that we use to scan or make a duplicate image that we enter into the computer system in digital form.
Etc.

The component that serves as Process (Processing) such as:

Random Access Memory / RAMA 
place to store the data in the short term or temporary. RAM will make the software that is being run and then keep it for a while, so when the computer running the duty he did not need to dance to data from the hard drive to get the data we need. Large or small amount of RAM will mempengruhi krcrpstsn computer. Ram larger number will speed up computer performance. 
Read Only Memory (ROM) 
Read Only Memory is a data storage medium that is contained inside the computer that is useful for storing information such as data in the long-term or permanent. So if the data has been stored in the ROM so it will not change, break or disappear after a power cut. 
Accelerated Graphics Port (APG) / Video Graphics Array (VGA) 
VGA or APG is a device that serves to support the power of the graphics contained on the computer by means of visual displays on the computer. 
Processor 
The processor is also dubbed as the brains of a computer. Because the processor has a duty as regulator or controller computer that is supported by component - other kompoen. The processor is an IC that serves to control the overall performance of the computer. 
Hard Disk
This one device is a device that has particularly function as a secondary data storage in a computer. 
CD-ROM / DVD-ROM
Is a piece of computer hardware that has an assignment to read as the data contained in the chip CD-R / DVD-R.

While included into component output (output) include: 
Speaker 
Speaker has a function as output or sound output that has been generated from the process if it were a computer. In addition to the speakers, sound output tool are also often encountered in the form of a headset / earphone that is frequently used by many people. 
Printer
 Is a tool that serves to print computer processed into paper media, either in the form of text, numbers and graphics that have been processed on a computer.
Monitor 
Also referred to as a screen, the display also. Seara physically resemble the shape of the television monitor. Monitor hardware is outside the computer case that serves to display an image, video, or graphical information generated from the processing tool in the form of a graphics card or VGA Card.In addition to a variety of hardware devices that have been clearly described above, is certainly not limited to that, and there are still many other devices that are included in the various categories of computer components, but what that has unraveled above are the most common devices and must belong to everyone who have a computer.
