Computer Security System

It has become an open secret, that the computer is a set of systems that greatly assist us as human performance. But if not protected properly, the computer can also be dangerous, such as viruses, spam, or even fraud under the guise of cyber crime.To prevent this occurrence we do not want that, then emerged a term that often we recognize as a computer security system. So what is a computer security system?Computer security system is a shield designed to protect from attacks that certainly is not our desire. The proliferation of computer users at this time, we as computer users whose name is in need of computer security systems. 
Moreover, coupled with the mutual connection of the user which one user to another which has now spread to all corners of the world via the Internet, of course we do not want when somebody does something we do not want to us. 
Computer security systems are closely related to the name of preservation and self-defense from attacks, harassment, and threats. For most ordinary people, this defense system is often also referred to as antivirus.Although the security system is very meaningful for us to computer criminals hard to disturb us, but this does not guarantee that we are safe that completely. But at least this program has been to minimize the disruption that threatens us all the time. 
Critical Aspects of Computer Security System 

In the computer security system there are some important aspects that we need to consider, include: 
Privacy

Privacy is the most important aspect that needs to be protected in a computer. It smelled of personal secrets do not want to be a time when terbeberkan by people who are not responsible. 
Confidentiality 

This aspect is also personal, it's just to keep spreading even though we have already secured. Which is classified in this aspect include personal biographical data such as full name, home address, and so on. Of course there are other objectives that one why privacy is disseminated. 
Integrity 

This aspect is more emphasis on an information that is confidential and modified by other parties. In most cases that often arises is the tapping of e-mail being sent. The possibility that there is the content of an e-mail will change when read by the recipient. 
Autentication 

This aspect concerns about the authenticity of the data entered when we access on a system. For example, we need a data and password are correct - it is valid for entry into a system.
Anticipation 

One way to support and implement security on the computer is to conduct defense, surveillance, and not carelessly do things that may harm. This can be done by installing a variety of antivirus, antimalware, firewall, and a variety of other software.

Another way is to restrict the movement of, for example do not stick any flash, not carelessly download files over the internet that obviously can harm your computer.Overall, the computer security system is required by all computer users. Another function is to protect the computer from harmful attacks such as malware, viruses and comrades.

History of Computer from the Start Up Now

Computer history begins with the discovery of Charles Babbage important form of calculators. Thanks to his discovery, he was known as the most influential scientists in the development of computers. Then, calculators were developed more gradually until now created a sophisticated device called a computer.

Stages in the development of so-called next-generation computers. There are five generations of computers, each of which has its own story. Thanks to the reliable hands of scientists and engineers at the time, the development of generation to generation seems so easy and organized.

Computers continue to be developed by the insertion of the latest innovations. Up to now, several leading companies working on high-tech computer with the computer name of the future.

History of Computers
Intelligent innovations have been taking part in the development of computer technology is so rapid. The development of computer innovation is divided into five generations. Here is a review of the history of computer development from the beginning until now, from generation to generation:
First Generation Computers
The device was first developed computer is the computer to design airplanes and missiles. Scientists who carried out the development concept was Konrad Zuse, a German engineer. Then, in the mid-1940s, the computer is experiencing further development conducted by John von Neuman.
The main characteristic of first-generation computer is the CPU. Yes, "central processing unit" contained in the first generation of computers was the first machine that is used to operate the entire system in a computer. While the main program contained in the first generation of computers is the "machine language".
Second Generation Computers
An important discovery has occurred in this second generation. Is a transistor, a powerful tool that can maximize computer performance with a very small size. The discovery of these tools affect the development of computers in the second generation. In the 1960s, scientists tried to work on the second generation of computers.
Some companies, universities, and the government has been to leverage the power of second generation computers. The essence of the invention are the second generation of transistors, which made the second generation is smaller than the first generation.
Third Generation Computers
In use, the transistors make computer faster heat. Thus, the second generation of computers becoming obsolete. Then a scientist named Jack Billy tried to do some research. Then in 1958, he created the components are more sophisticated than the transistors that make fast computer last summer. Namely IC, or integrated circuit tiny chip that can accommodate many components into one.
By doing so, the size of computers become smaller. Also, the third-generation sector is also faster operating system and capable of running multiple programs simultaneously.
Fourth Generation Computers
In this generation, which uses computer chip IC later developed. Very Large Scale Integration company trying to do the development in the 1980s. As a result, a single chip can hold thousands of components.
From here, the term "personal computer" or PC appears. That is, the computer began to be marketed to individual sectors. Do not stop there, there arose a computer device that is easy to carry anywhere, the Laptop.
Fifth Generation Computer
Fifth generation computers are currently being carried out by various vendors electronically. Yes, the fifth generation computer is often referred to as the next generation computer. Some small evidence is the emergence of smartphones, tablets, phablet, netbook, ultrabook, and lots more.

The next development is a computer tool that can be run without having to use physical contact (touching), but use your brain. Then, will the fifth generation computer is realized? Only time that can answer.

So a bit of information about a brief history of the computer and its development from generation to generation. May be useful.

Getting in History of Computer Network in the World

The history of the world computer network begins with research US Department of Defense, the Defense Advanced Research Project Agency (DARPA), the research that is often identified as the ARPANET in 1969 on how to be able to connect a computer to other computers in order to form an organic network. As a result, DARPA successfully connecting more than 10 computers that form a network and can communicate with each other.

History of Computer Networking Year 1972-1979

The success of the ARPANET research was also marked by the success of a communication program which we now know as e-mail in 1972. Roy Tomlinson is the originator of the e-mail program that he created for ARPANET.The ease of use of e-mail have made it so popular in his time. And in 1972 was also an icon @ claimed to be so important symbol meaning "at" in Indonesian which means "on".In 1973, ARPAET computer networks are widely popular outside the United States. History shows that the first computer to be a member of the ARPANET network outside the United States is a computer University College in London.And in the same year was presented was an idea that underlies thought the International Network by two people hostage in order in the computer field named Vinton Cerf and Bob Khan at the University of Sussex. Day that will always be remembered history was when the Queen of England managed to send an e-mail from the Royal Signals and Radar Establishment in Malvern. Over a year later, forming a network consisting of more than 100 computers that have joined the ARPANET.The next historic year occurred in 1979, when three people namely Jil Ellis, Tom Truscott and Steve Bellovin, managed to create USENET newsgroup which is the first in the world.Two years later, in 1981, France Telecom succeeded in shocking the world by launching the world's first television phone that allows people can call while associated with the video link.In 1982 formed the Transmission Control Protocol or what we now know with TCP and IP. This is due to the growing number of computers that form a network, it needed a formal protocol that can be recognized by all network users.Meanwhile, the Europeans did not want to lose, then comes a computer network that is predicted as a rival ARPANET network known as Eunet, which provides computer network services in various countries such as Sweden, the UK, the Netherlands, and Denmark.Eunet also provide USENET newsgroups and e-mail. Then in 1984 introduced was the Domain Name System (DNS) that is used to homogenize the address on the computer network.
History has recorded a surge in the number of computers that join a network that is as much as 10-fold to 10,000 more previously only 1,000 more in 1987.

History of Computer Networking Year 1988-1994 

Further history occurred in 1988, when the introduction of a communication program called the Internet Relay Chat (IRC) by Oikarinen of Finlad. A year later an explosion of the number of computers that are shaping the network, more than 100,000 computers have formed a network at that time.Then the invention of Tim Bernes Lee called www or World Wide Web is a program editor and browser that allows the exploration of data from one computer to another has made in 1990 to be the year's most historic, complementing a computer network history.Not to long ago, namely in 1992 a computer that is mutually connected into a network form not less than one million computers. And in the same year and then comes a surfing term that means browsing or surfing.And in 1994, no fewer than 3000 addresses the virtual world sites have sprung up each other. In the same year stood Yahoo, which is also the history of the birth of Netscape Navigator 1.0.

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
