1. Understanding Computers
Here are some computer terms
1. Computers are a series of electronic machines or a group that consists of thousands and even millions of components that can cooperate with each other, and formed a working system neat and meticulous. This system can then be used to carry out a series of jobs automatically, based on the order of instructions or programs provided to him.
2. Computers are the result of the progress of electronics and informatics technology that serves as a tool for writing, drawing, editing pictures or photos, create animation, scientific analysis program operates, simulation and for control equipment.
3. Computers are a tool to ease the job supporting the human in the process of solving various problems, because these devices have the operational speed, the ability to save memory, reliable, and cost saving. source: TIK Class XI book published Widya Utama
2. Characterization Computers
Computers can be classified based on the processed data, computer skills, capacity and size, and the problem area.
2.1. Based on the data being processed, the computer classified into three, namely:
1. Analog computer
Is a type of computer that can be used to process qualitative data. The data is not a symbol, but still a state. Like for example: state of the air temperature or humidity, altitude or speed is a condition defined by the computer then that becomes a measure.
Analog widely used dipabrik-tujuannnya plant to control or produce a product. The definition is closer to analog computer with a robotic or automated machinery.
2. Digital computer
Is a type of computer that can be used to process data that is quantitatively (very many in number). Data from a digital computer is usually a symbol that has a specific meaning, for example: aphabetis symbols depicted with the letters A s / d Z, or as / dz, a numerical symbol represented by numbers 0 to 9, or special symbols, such as: ? / + * &!.
3. Hybrid computer
Is a type of computer that can be used to process data and quantitative or qualitative. Hybrid computer can also be said as a combination of analog and digital computers. This kind of computer system used by the various hospitals which used to examine the circumstances of the patient's body, which in turn, can release a variety of computer analysis presented in the form of images, graphics or text.
2.2. Based on ability, computers classified into three, namely:
1. Small scale computer
This kind of computer system has a capacity of 64 Mb to 8 Mb and can handle dozens of separate computer terminals of the computer center.
2. Medium scale computer
This kind of computer system has a capacity of between 512 Kb to 8 Mb and can handle hundreds of separate computer terminals of the computer center.
3. Large scale computer
This kind of computer system has a capacity of between 512 Kb to 8 Mb, but this computer has a higher speed.
2.3. Based on the capacity and size, computers are classified into three, namely:
1. Microcomputer (Personal Computer / PC)
At first, this kind of computer system created to meet the needs of the individual (personal). Individual needs in terms of storing or processing data, certainly not as much need for a company. Because of this, capabilities and technologies owned by the Personal Computer in the beginning was very limited.
With the benefits of relatively cheap price, small form-owned technology bet is already sufficient, then the personal computer became so popular so quickly. Personal computers are now not only used by individuals but in the end is widely used by companies to solve various problems diperusahaan.
a. Notebook / Laptop
Is the type of PC that can carry and can be used anywhere because it is equipped with a portable battery-power, so that without any electric-note-book can still be operated
b. PDA / Pocket Computer
Is a kind of pocket-sized PC that can be taken anywhere.
2. Midrange computer or mini computer
Mini computer has the capability of times greater when compared with the personal computer. This is caused by micro-pocessor used to process the data does have the ability far superior when compared with that used in micropocessor personal computers. Pisiknya size can for a small cupboard.
Mini computer in general can be used to serve more than one user (multi user). In this multiuser system, in the end personal computers are widely used as a terminal that serves to enter data. Example Minicomputer: IBM AS-400
3. Mainframe computer or mini computer
The main characteristic that distinguishes the notion of mini-computers to mainframes is, the mainframe has more than one processor. Thus, in terms of speed mainframe process much faster when compared with mini-computers.
Mainframe generally requires a special room where the environmental factors of temperature, humidity or smoke problems it can be monitored. This is because the value of the computer and the value of information stored in it is very expensive. The room is usually equipped with various electronic security systems.
4. Super Computer
As the name implies, the super computer has characteristics, namely high-speed process and have the ability to store data much larger when compared with the main-frame. The price is very large super computer and expensive. Satau One example is the super computer Cray-2. Super computer users are the countries that have developed or companies that are large, such as IPTN aircraft industry.
Due to the ability extraordinary and include the ability to read / tap various data from the satellite, then to purchase a super computer to get approval directly from the president. Indonesia has rejected a request by the American president when Nurtantio want to buy a super computer from the United
2.4. Based on the problem area, computers are classified into two, namely:
1. Special purpose computers
This kind of computer system can only solve one problem only, so only certain programs are intended in this computer. For example, computers used in oil refineries.
2. General-purpose computer
This kind of computer system can solve many problems. Computers are included in this type, ie digital and analog computers, but is commonly used digital computer. For example, computers and computer education for business. Canon PIXMA MX860 Wireless All-In-One office Printer
