Principles of Good Wiring

Cable is the foundation of any computer network. Without planning and installation are eligible, problems can arise from things that are not unexpected. In a certain scale, to address the issues of this kind may be needed efforts take time and exhausting, and this often means a network that forced non-active for long periods of hard to predict.For critical networks (critical systems) in an organization that puts the network activity as one of the business requirements, problems that lead to network downtime can not be tolerated. Therefore a comprehensive design, planning, measurable, and installation is a series of structured processes that need to be pursued seriously. The following are the principles that need to be considered in a structured network cabling (Structured cabling Systems-):
• The network has never been smaller or less complexity.
• Build a cabling system that is able to accommodate the needs for voice and data transmission.
• Always install the cable in excess of current needs. Extra cable is not needed now will be useful someday.
• Adhere to the standards set forth in the structured-cabling Standards when building a new cabling system. Avoid using proprietary tech cable.
• Use the cables and components are of high quality. Failure to turn off cable's most sophisticated applications. Quality does not always correlate with the price. Use the cable on the basis of reference, which has proven performance, and reputation of the manufacturer of quality cable.
• Install properly. Even with the best quality cables will not be meaningful without good workmanship.
• Plan for future needs. Just because Ethernet 1000BaseT impressed not too useful at this time, does not mean there will be an absolute need for the next 5 years.
• Documentation, documentation, documentation.

IEEE 802.3

IEEE 802.3 is a frame format which is the result of a merger of the specification IEEE 802.2 and IEEE 802.3, and consists of an IEEE 802.3 header and trailer and a header which the IEEE 802.3 IEEE 802.2 defines the physical layer and media access control sublayer of the data-link layer of the Ethernet standard wired
Here are some examples of standard IEEE 802.3 (Ethernet):
• Speed ​​10Base2 10Mbps, baseband technology, cable lengths up to 185 meters.Known as thinnet and can support up to 3 hosts in a single cable segment. Using a bus topology, both physically and logically with AUI connectors. Number 10 means 10 Mbps, base means using baseband technology, and the number 2 means the maximum distance of 200 meters before requiring a repeater. Network cards (NICs) using 10Base2 BNC connector (British Naval Connector / Bayonet Nut Connector / Bayonet Neill Concelman), and T-connector for connection to the network.
• Speed ​​10Base5 10Mbps, baseband technology, cable lengths up to approximately 500 meters. Known as Thicknet, using the topology of physical and logical bus with AUI connectors. Can reach 2500 meters with several repeaters and able to handle 1024 users for all segments.
• 10BaseT speed of 10Mbps, baseband technology, cable lengths up to 100 meters, using UTP cable category 3 (Cat 3). Unlike the 10Base2 and 10Base5, 10BaseT every device on the network must be connected through a hub or switch, and allowed only one Hub / Switch on each segment of cable. Using the RJ-45 connectors (8-pin modular connector) with a physical star topology and logical bus topology.
• 100BaseTX Speed ​​100Mbps, baseband technology, cable length 100 meters.Using 2 pairs of UTP cable with category 5, 5e or 6. There is only one host in a single cable segment, use an RJ-45 with a star topology (Star) physical and logical bus topology.
• Using 100BaseFX multimode fiber optic cable 62.5/125 micron size with a length of up to 412 meters. Using the ST or SC connectors with the topology of point-to-point.
• 1000BaseT speed of 1Gbps, using Category 5 UTP cable (Cat 5 and Cat 5E) 4 pair, with cable lengths up to 500 meters.
• Represents 1000BaseLX Singlemode fiber optic with a size of 9 microns and the signal emitted by laser 1300 nanometers. Can work with a distance of 30-10 kilometers.

WiBro

WiBro (Wireless Broadband) is a portable Internet service (can be used anywhere)are emitted at a frequency of 2.3 gigahertz (GHz). WiBro enables broadband Internetaccess to a variety of devices including mobile phones, computers, notebooks,PDAs, and others. In terms of mobility, WiBro also considered more efficient andeffective than the now standard WiFi wireless internet. WiFi coverage is still limited toroughly within a radius of up to 100 meters, while Wibro claimed to be accessible to within 1 kilometer from the transmitter station. It is remarkable advances in technologythis time?
Access is also called WiBro is still acceptable in the vehicle speed 60 kilometers perhour. WiBro was developed by a large company named Samsung along withElectronics and Technology Research Institute (ETRI) and has received certificationfrom the WiMAX Forum. This technology is capable of transmitting data at speeds up to 50 Mbps. Data transfer speeds are able to surpass the speed of HSDPA data transfer platform that has the ability to send data to 14 Mbps.
WiBro is a further development of Korean-made technology standard calledhigh-speed portable internet (HPI). The developers include Corps KT, SK Telecom,and Electronic & Telecommunications Research Institute. Now HPI technologystandards are deemed to include one of the global technical standards given the HPIuses 802.16e standard from the Institute of Electrical and Electronics Engineers(IEEE).

Web OS

Web Operating System is an equation of the operating system, but with the capabilityprovided in the programming model Asynchronus JavaScript and XML data (AJAX)allows us to create a web application where the web is capable of processing only certain objects and let objects do not participate in the process into the web process(such as regular web). In this case that is described is a web operating system calledGlide Web Operating System which is made ​​by a developer named Transmedia. This service can be accessed by other computers (either notebook or PC), we also can access via mobile phones such as iPhones and PDAs that use a web browserapplication. This service has a Glide Write for word processing. In making the presentation, this service has a Glide Presenter. This service also provides a GlideWeb Publishing, which serves to create a web page. In this service facilities to editpictures online using PhotoEdit. And many other interesting applications.

TCP/IP

Transmission Control Protocol / Internetworking Protocol (TCP / IP) is a protocol that describes how all the transmissions that can be done via the Internet.

The basic concept addressing format of TCP / IP using a protocol called IP which has a length of 32 characters which are divided into 2 fields, namely netid and hostid;where netid is the network where the host is connected and the hostid is a uniqueidentifier for each host on a network. IP addresses are written as 4 where thenumerical value in a single numerical value, there are 8-bit binary number.

In the IP addressing class, divided into five classes where the class A of 0.0.0.0 - 127 255 255 255; Class B between 128.0.0.0 - 191 255 255 255; Class C between192.0.0.0 - 223 255 255 255; Class D between 224.0.0.0 - 239 255 255 255; Class Ebetween 240.0.0.0 - 255 255 255 255; To get the address previously used in thecalculation of binary numbers. For more details can be seen below table:

So little that I can share with and hopefully can be useful for friends as well. If there is a problem please share so that the problem can be solved together.

Compression

compression aims to condense data so that data obtained will be smaller than its capacity so it does not need to require a large storage space. Lots of data can becompressed, such as images, documents, videos, and others. From the material Ilearned there are two kinds of compression techniques, the lossless compression andlossy compression.

1. Lossless compression

The original data obtained from lossless compression cans be recovered from itscompressed data

e.g. Huffman Coding

2. Lossy compression

Compressed data of lossy compression can not be recovered to the original data.

e.g. JPEG (still images), MPEG (video / motion image)

ASCII Code

ASCII is a continuation of the American Standard Code for Information Interchange isan international standard that consists of letters and symbols such as hexadecimalnumbers and ASCII unicode but more universal. ASCII code used in computers in particular, so that each translation language requiring translation into ASCII numbers in advance and then change again to form another. ASCII code is actually a binary number consisting of 8 bits which started from 0000 0000 to 1111 1111 where forbinary numbers consisting only of numbers 0 and 1. Usually we are not able tomemorize the ASCII code of the need to write or scribble in order to be translated. So that we can interpret quickly the need for assistance in the form of an ASCII table.Therefore, I will share with the ASCII table to you all so friends can use it either to studyor to work.

Using the Auto Lock RFID Card

RFID (Radio Frequency Identification) is a tool used to store or receive data at acertain distance using a device called RFID tags or transponders. RFID tags containantennas that enable the tag to receive and respond to a query that is emitted by anRFID transceiver.

Today, RFID applications are very attractive and corpulent developed. One is theapplication of RFID in the door lock automatically. Connections that use RFID readerusing air or wireless media where the RFID reader used to read the card ID that is used in EM 4100. RFID reader does not require great resources, it is proven that it works at 5 V DC voltage with a frequency of 125 KHz. RFID reader is equipped withauto-tuning and DSP (Digital Signal Processing) to improve the reading range and toreduce unwanted vibration and interference. When brought near the RFID tag with an RFID reader, the reader will read the ID contained in the card. Output reader is aninput to the microcontroller AT89C51 where output has been spending a format that isABA Track2 10 decimal. Input data from the RFID reader will read is then stored and compared. The output of the microcontroller is connected to the PNP transistor 9012is used as a switch connected to the relay to move the key. Initial state relay and the transistor is normally closed and cut off, and work in the flip-flop in accordance with the input of the microcontroller that is connected with a DC motor that will move thegear to open and close the door.
