CLOUD COMPUTING

     

     

     CLOUD COMPUTING is the very latest technology enable people to access the data, which incorporates a combination of computer technology and cloud storage, both on hardwares and softwares.

     CLOUD COMPUTING can store various types of data that we have, such as documents, musics, videos, photos, and other. The data stored in it are permanently stored in the Internet server and can be accessed through a computer, tablet PCs and smartphones to edit, save, and delete. Existing data can be accessed at the same time with our friends, as long as it connected to the internet and log in to his ID, respectively.

CLOUD COMPUTING service models:

1. Infrastructure as a Service (IaaS).

     IaaS is a model of the most basic services, namely computer resource rent directly. These services are often encountered in cloud server web hosting as well as cloud VPS (Virtual Provider Server). The use of cloud technology allows users to create many virtual servers or adjust the level of resources in accordance with their wishes.

Examples of service provider is Linode, HP Cloud, Joyent, NaviSite, and other.

2. Platform as a Service (PaaS).

      In the PaaS services, cloud provider will usually provide a platform that includes the operating system, database, web server, and the programming language environment. Users can develop applications using the platform that has been provided. Users can also set the resource to fit their needs with ease.

Example of service provider is Jelastic, Heroku, Google App Engine, Windows Azure Cloud Service, and other.

3. Software as a Service (SaaS).

      SaaS is currently being fast-growing and often we meet in person. Here the cloud provider will provide software or application in the cloud that can be accessed by users via the internet. Users can not access the infrastructure or platform on which the application runs, they could only access, execute and take advantage of the application.

Examples of service provider is Microsoft Office 365, Google Apps, OnLive, Petrosoft, and other.

4. Network as a Service (NaaS).

      In Naas cloud service provider will provide network / connectivity. Users can use the network or connectivity in the cloud.

Example of service provider is VPN and bandwidth on demand.

WI-FI (WIRELESS FIDELITY)

Wi-Fi (Wireless Fidelity) is a wireless networking technology that uses radio waves to provide network connectivity and Internet high speed level.Wi -Fi Alliance, an organization that has Wi-Fi trademark term, specifically defines Wi-Fi as part of the product WLAN (Wireless Local Area Network) based on the standards of the Institute of Electrical and Electronics Engineers (IEEE) 802.11. Wi-Fi is easy it also means the IEEE 802.11x.

Initially, Wi-Fi is used only in the 2.4GHz 802.11b standard, but Wi-Fi Alliance has expanded its use of the term Wi-Fi to any type of network or WLAN products based on 802.11 standards, including 802.11b, 802.11a. dual-band, and others.

Wi-Fi to work without using a physical connection between sender and receiver cables, but with the technology of Radio Frequency (RF), a frequency within the electromagnetic spectrum associated with radio waves. When RF is supplied to an antenna, the electromagnetic, will be made and entered into a corner of a wireless network called an Access Point (AP). The main task is to spread AP (broadcast) wireless signal is detected on the computer and 'entry' into it. To connect to the AP and join the wireless network, computers and devices must be equipped with wireless network adapters.

Wi-Fi is available at: video game consoles, home networks, PDAs, mobile phones, operating systems, and other types of electronic products. Product that has been tested using a Wi-Fi will be labeled Wi-Fi Certified by the Wi-Fi Alliance.

GOOGLE CHROME FOR WINDOWS,MAC,AND LINUX

The world's largest search engine, which is headquartered in the U.S.A , Google, has launched the latest version of the browser, Google Chrome for Windows, Mac and Linux.Brian Rakowski, Google Chrome Product Manager explains "Since the end of December last, we have to test and build new features for Mac and Linux can work with Chrome like any version of Windows. And finally today we announced that for the Mac and Linux versions are available. ". Google itself says that the new version was launched it was included in the fastest version. "We've developed a Javascript performance between 213% and 305% with V8 and SunSpider benchmark since our first beta version of Chrome on the Cretaceous period in September 2008 who then" added Rakowski.

In addition to speed so fast, other features created by this new Chrome, among others, the ability to perform the sync browser (bookmarks, themes, settings and startup homepage, web content settings, preferred languages and the page zoom setting) at different types of computers, the ability to read HTML5 (Geolocation API, App Cache, Web sockets and files drag-and-drop), and the most recent bookmarks manager. According to Rakowski HTML5 features the ability to try, try browsing to a website that you built using platforms such as scribd.com HTML5, then try performance drag-and-drop in Gmail or enable Geolocation feature on Google Map. Google also plans to open the Chrome Web Store that will provide a gallery of web applications that not only work for Chrome.

Come immediately download and use the latest version of Google Chrome this!

BLUETOOTH

Wireless networking standard, which was launched in essence is to use short range radio link or a short-range radio link to exchange information, so that the relationship between the mob, mobile PCs, PDAs, and more can be done without a cable or wireless interference.

The purpose of this launch include bluetooth is to change the specification of the IrDA InfraRed on hp and other mobile devices.Bluetooth provides a 720 Kbps data transfer within the range of 40 feet. Bluetooth uses radio waves are omni directional and can pass through walls. This is different from that IrDa technology and the need to look each other in order to make contact.

Ericsson to give their contribution to radio technology, Toshiba and IBM to develop a specification for integrating Bluetooth technology) (mobile.Intel equipment into their expertise in chip and software, while Motorola contributed their expertise in radio technology and mobile handset software.

Many other companies are also invited to support the core technology that this technology is expected to be used in many devices. This radio will operate at 2:45 GHz ISM free band) (Industrial Scientific Medical), which allows international users with equipment that is equipped with Bluetooth can use their equipment anywhere throughout world.

The name Bluetooth comes from King Harald Bluetooth of the Danes. Ericsson (a Scandinavian company) is the first company to develop this specification.

INTERNET HISTORY

The Internet is a computer network established by the United States Department of Defense in 1969, through a project called ARPANET. ARPA (Advanced Research Project Agency Network), where they demonstrated how the hardware and software UNIX-based computers, we can make communication within the infinity through the phone line. ARPANET project designing their networks, reliability, how much information can be moved, and eventually all of the standards they set into the embryo development of new protocols now known as TCP /

IP (Transmission Control Protocol / Internet Protocol).

The initial purpose was the construction of the project for military purposes. At that time the United States Department of Defense (U.S. Department of Defense) create a computer network system that is spread by linking computers in areas vital to overcome the problem occurs when a nuclear attack and to avoid the occurrence of centralized information, which in the event of war can be easily destroyed.

At first ARPANET link is only just 4 sites of the Stanford Research Institute, University of California, Santa Barbara, University of Utah, where they form a single integrated network in 1969, and in general the ARPANET was introduced in October 1972. Not long after the project is growing rapidly in all regions, and all the universities in these countries want to join, thus making it difficult to arrange the ARPANET.

Therefore split ARPANET split in two, namely "MILNET" for military purposes and the "ARPANET" new smaller for non-military purposes such as, universities. Combined both networks eventually known as the DARPA Internet, which then reduces to the Internet.

TOUCH SCREEN

Touch screen can be defined as a computer display screen that is sensitive to human touch, so a person can interact with the computer by touching pictures or text posted on the computer screen.

In other countries like the United States, touch screens can be found at airports, hospitals, or in a bank ATM. However, we do not need all the way to America just to see the touch screen. In Indonesia too, we can see and use the touch screen in a variety of gadgets, such as Mobile, tablet PCs, PDAs, and so on.

One type of trusted touchscreen supreme until now is Capasitive touchscreen. Because this type of touch screen can only work if the touches aimed at him from conducting objects such as our fingers. Unlike other types of resistive or surface wave that can be touched with a finger or stylus, touch screen can only be operated by finger alone. With these properties, the touchscreen is not easily affected by interference from other objects on it such as dust or water.

Screen display is very clear than that of resistive touchscreen is ideal for use in a variety of purposes in the general public interaction such as in restaurants, electronic kiosks, Point of sales locations, and much more.

OPERATING SYSTEM (OS)

Operating System or OS is the system software responsible for the control and management of hardware and basic operations systems, including software applications running programs like word processors and web browsers.
In general, the Operating System software on the first layer is placed on the computer's memory when the computer boots. While other software is run after the operating system running, and OS will make public the core services for the software. Common core services such as access to the disk, memory management, skeduling task, and user interfaces. So that each software no longer need to perform the core duties of the public, because it can be served and performed by the operating system. Section of code that perform the core duties and the public is called the "kernel" of a Operating System
If the computer system divided into layers, then the Operating System is the liaison between the layers of hardware and software layers. Further than that, Operating System do all essential tasks in the computer, and ensure that applications can run different simultaneously smoothly. Operating System ensure other software applications can use the memory, perform input and output of other equipment, and have access to the file system. If several applications running simultaneously, then the operating system appropriate arrangements, so far as possible all the processes running to get enough time to use the processor (CPU) and do not interfere with each other.
In many cases, operating system provides a library of standard functions, which other applications can call functions, so that in every creation of new programs, no need to create these functions from scratch.
Operating systems generally consist of several parts: 1. Boot mechanism, which is putting the kernel into memory
2. Kernel, which is the core of an Operating System
3. Command interpreter or shell, which served to read input from the user
4. Library-library, which provides a collection of basic functions and standards that can be called by other applications
5. Drivers to interact with external hardware, as well as to control them
Some operating system only allows one application are running at one time (eg DOS), but most of the new operating system allows several applications running simultaneously at the same time. Operating systems like this is called the Multi-tasking Operating System (eg the UNIX operating system families). Some Operating Systems are very large and complex, and its inputs depending on the user input, while the other Operating Systems is very small and made with the assumption that work without human intervention at all. The first type is often referred to as a Desktop OS, while the second type is the Real-Time OS

ELECTROMAGNETIC RADIATION

Electromagnetic radiation is a combination of electric and magnetic fields that oscillate and propagate through space and carrying energy from one place to another. Visible light is one form of electromagnetic radiation. Theoretical studies of electromagnetic radiation called elektrodinamic, sub-field of electromagnetism. Electromagnetic waves discovered by Heinrich Hertz. Electromagnetic waves including transverse wave.

Any electric charge which has acceleration emit electromagnetic radiation. Left wire (or conductor as an antenna) conducts alternating current, electromagnetic radiation transmitted at the same frequency electrical current. Depending on the situation, electromagnetic waves can be like a wave or as particles. As a wave, characterized by the velocity (speed of light), wavelength, and frequency.

When considered as particles, they are known as photons, and each has the energy associated with the frequency indicated by the Planck relation E = H.ν, where E is the photon energy, H is Planck's constant - 6626 × 10 -34 J • s - and ν is the frequency of the wave. Einstein then update the formula becomes Ephoton = hν.

Which includes an electromagnetic wave:

Wave and wavelength( λ) :radio waves 1 mm, 10,000 km, Infrared 0,001-1 mm ,visible light 400-720 nm ,ultra violet 10-400nm, X rays 0,01-10 nm ,gamma rays 0,0001-0,1 nm ,cosmic rays do not include electromagnetic waves; smaller wavelength of 0.0001 nm. Light with large wavelength, the radio waves and infrared, has a frequency and level of lower energy. Beam with a wavelength smaller, ultra violet, x-rays or Roentgen rays, and gamma rays, has a frequency and energy level higher.

COMPUTER NETWORK

Computer network is a system consisting of computers and other network devices that work together to achieve a common goal. The purpose of the computer network are: 1.Share resources: for example, shared use of printers, CPUs, memory, hard drive 2.Communication: for example electronic mail, instant messaging, chat 3.Access to information: for example web browsing In order to achieve the same goal, each part of the computer network and provide service request (service). Party requesting the service is called a client (client) and that provide services called the servant (the server). This architecture is called client-server systems, and is used in almost all computer network applications. Classification Based on the scale: 1.Personal Area Network (PAN) 2.Campus Area Network (CAN) 3.Local Area Network (LAN): a computer network that connects a computer to another computer with a limited distance. 4.Metropolitant Area Network (MAN): principle the same as LAN, only the larger distance, ie 10-50 km. 5.Wide Area Network (WAN): the distance between cities, countries, and continents. This is the same with the Internet. 6.Global Area Network (GAN) Based on the function: Basically every computer network is functioning as a client and server. But there is a network that has a dedicated computer as a server and the other as a client. There is also a computer that has no special function as a server only. Therefore, based on their function there are two types of computer networks: 1.Client-server Network is the computer with a dedicated computer as a server. A service / service can be provided by a computer or more. An example is a domain like www.detik.com lots served by the web server computer. Or it could be a lot of service / services provided by a single computer. Examples are jtk.polban.ac.id server that is a multi-service computer with the mail servers, web servers, file servers, database servers and others. 2.Peer-to-peer Namely computer networks where each host can be a server and also a client simultaneously. For example in the file sharing between computers on the Windows Network Neighborhood Network have 5 computers (we give the name of A, B, C, D and E) that provide access rights to the files they have. At one point A to access the file share of B named data_score.xls and also gives access to the file problem_uas.doc C. When accessing a file from B then A serves as a client and as a give file access to C then A serves as a server. Both functions were performed by the same A network like this is called peer to peer. Based on network topology, computer networks can be divided into: 1.Topologi bus 2.Topologi stars 3.Topologi ring 4.Topologi mesh 5.Topologi tree 6.Topologi linear Based on the criteria, the computer network can be divided into 4, namely: 1. Based on the distribution of sources of information - This network centralized network consisting of Client and server computers which Client computer that serves as an intermediary to access sources of information / data derived from a single server computer - Network is a combination of several distributed centralized network so that there are several computer servers that are interconnected with the Client to form a specific network system. 2. Based on geographic coverage can be divided into: Network LAN is a network that connects 2 computers or more in coverage such as laboratories, offices, and in 1 cafe, MAN network is a network that includes a big city and its local area. Examples of local telephone networks, cellular telephone systems, as well as some ISPs relay network Internet, Network WAN is a network with coverage throughout the world. PT network example. Telkom, PT. Indosat, as well as GSM networks such as Cellular Satelindo, Telkomsel, and much more. 3. Based on the roles and relationships of each computer in the data processing. Network Client-Server In this network there are 1 or more server computers and client computers. Computers will be computers or servers to client computers and altered through the protocol software on the network. Client computer as an intermediary to be able to access data on a server computer and the server computer to provide information needed by the client computer. -Network Peer-to-peer in this network there are no client computer or server computer because all computers can make sending and receiving information so that all computers function as clients as well as a server. 4. Based on the data transmission media. Wired Network (Wired Network) In this network, to connect one computer to another computer in the form of necessary liaison network cable. Function in the network cable to send information in the form of electrical signals between the network computer,Wireless Network (Wireless Network) is a network with the medium of electromagnetic waves. In this network does not need a cable to connect between computers that use electromagnetic waves to send signals between the computer information network

COMPUTER HARDWARE

Hardware is all the physical parts of the computer, and are distinguished by the data in it or who operate in it, and are distinguished by the software (software) that provides instructions for the hardware to complete the task.
Boundary between hardware and software will be a little blurry when we speak about firmware, because this firmware is software that is "made" into the hardware. This firmware is the area of computer science and computer engineering, which is rarely known by the general user.
Computers in general is a personal computer (PC) in the form of a desktop or tower box consisting of the following sections:
1.Mother board which houses the CPU, memory and other parts, and has a slot for additional cards.
2.RAM where short-term data storage, so the computer does not need to always accesthe hard disk to find data. The number of larger RAM will help speed your PC Buses: PCI Bus ISA Bus USB AGP
3.ROM (Read Only Memory) in which the firmware is put
4.CPU (Central Processing Unit) as the main part of the brain and the computer
5.Power supply - a box which houses the transformer, voltage and fan control
6.Storage controller, the type of IDE, SCSI or something else, which controls the hard disk, floppy disk, CD-ROM and other drives; controller is located on the main board (on-board) or the additional card Controller video performance that produces output for computer displays

7.Computer bus controllers (parallel, serial, USB, Firewire) to connect the computer with other external additional equipment such as printers or scanners
8.Several types of computer storage: CD - the most common type of removable media, cheap but easily broken. CD-ROM , CD-RW , CD-R , DVD ,DVD-ROM , DVD-RW , DVD-R
9.Floppy disk Storage in - store data in a computer for long-term use.
10.Hard disk - for long-term data storage Disk array controller
11.Sound card - translates signals from the system board to the language that can be understood by speakers, and has terminals for the cable striking the earphone.
12.Computer network - to connect the computer to the Internet and / or other computers.

13.Modem - for dial-up connections.
14.Network card - for Internet DSL / cable, and / or connect to another computer.
In addition, hardware can include other external components. Below is a standard component or commonly used.
