It is the competition which uses the opposition type video game where high-level technical skill becomes necessary in operation. It is the electronic game as one kind of sport competition.

In type of game which is used for e-Sports, FPS (First Person Shooting: First person shooting) and RTS (Real Time Strategy: The real time strategic game) there is a sport game of other things and the tennis etc. Although with these games the reflected nerve and accuracy of operation and the judgment etc whose circumstance is fast are required, rival technical skill as a competition, it has happened to have the sufficient element.

The competition meeting of e-Sports is opened and the prize is applied and circumstances of the conference are offered by the audience with the various media to rivaling partly due, in the same way as professional sport it can enjoy as the entertainment have become something which.

ESSID

Reading: [iesuesuaidei]
Full spelling: Extended Service Set Identifier
Field:
LAN > Wireless LAN > ESSID

At one of the identifiers of the network in the wireless LAN of the IEEE 802.11 series, those like the network name which is attached in order to avoid the radio interference. The alphanumeric to maximum of 32 letters can be set optionally. SSID which is the identifier of access point, in order to be able to use even with the network which installs plural access points those which are expanded. Presently when the language, SSID in the sense of ESSID is used is many.

The wireless LAN using radio wave, in order to communicate, plural networks and becomes communication possible different from wire LAN, there is a possibility “radio interference” state occurring. Because of this, it is possible in access point of the wireless LAN, and each terminal to set ESSID, it is possible to try to communicate with only the terminal where ESSID agrees. You can connect to every access point there is special ESSID, “ANY”, but considering in security depending upon the product, there are also some which had the function which denies the connection from the terminal “of ANY” setting.

ESS-ID stealth

Security > network > ESS-ID stealth

At security functional one of wireless LAN access points, stop the beacon signal which informs about itself ESS-ID around.

In access point of the wireless LAN, ESS-ID which is the identifier of network as the function which is decided with IEEE 802.11, is dispatched around is “a beacon signal” function in every fixed time. In order for the equipment which we would like to connect to be able to search network easily, but the function which is prepared, also the user other than the proper user discovering network easily, because connection can the fact that is tried, it can become the weak point with respect to security.

If ESS-ID stealth is used, it can stop the beacon signal, in order existence of network not to be inspected around easily, it is possible to use. It is necessary for the proper user to procure ESS-ID of the network with expedient other than the wireless LAN, to set to the computer. However, because as for the packet itself of the network sky it is flying about, it is necessary not to become with fundamental security measure, to jointly use encoding and the like.

e-Tax National tax electronic declaration tax payment system

Field:
IT and society > administration/policy > e-Tax

The system which can declare national tax via Internet, the net banking and they can pay tax with ATM and the like. It does not go to the tax office and declaration of income tax and income tax and consumer tax etc can do also the [te], opening agency overtime of the tax office and procedure is possible even with holiday.

e-Tax is utilized, it is necessary to install the private software where it submits the specified application book, acquires the electronic certificate for electronic signature, is mailed with CD-ROM to the personal computer. As for the electronic certificate IC card and the like of the public private certification service where Ku municipalities issue being available, in case of IC card the card reader which corresponds becomes necessary.

e-Tax was started in 2004, but procedure to start of utilization being troublesome, spread is not advanced from the fact that time is required.

ETC Automatic fee taking in receiving system

Reading: [iteishi]
Full spelling: Electronic Toll Collection
Field:
IT and society > ITS/[teremateikusu] > ETC

The terminal which is loaded onto the antenna and the automobile which are installed in the fee place and the like of the toll road (the ETC load vessel) with it communicates, to stops the automobile the system which processes the fee payment and the like of the toll road.

ETC reduced the cost which is necessary for the collection of fee, was developed with the purpose which eases the procrastination which occurs frequently at the fee place. Approximately, it is utilized in 20 countries, but individual system is adopted every country, (there is also a country where plural systems have coexisted) for the sake of, in the country you cannot use the ETC load vessel which is distributed in the foreign country. However, in the Japanese country standard of the ETC-related equipment is standardized.

Concerning the method of deciding the payment person, system and the ID card etc which lock the payment person in every ETC load vessel there is a system which designates the owner of inserting and the ID card as the payment person in the ETC load vessel, in Japan latter is adopted. In Japan the contact type IC card which the credit card company issues is adopted as is suitable to this ID card. The case where the fee place is passed this IC card is inserted in the ETC load vessel, fee the future credit card company by way of, has become the mechanism which is claimed.

Ethernet

The Xerox corporation and the DEC corporation (presently one section of Hewlett Packard corporation) the LAN standard which is devised. Ethernet was standardized by IEEE 802.3 commission. CSMA/CD is adopted to access control. Presently, excluding special use, most LAN are Ethernet.

Bus type and the concentrator which share 1 these circuits with the plural equipment (the hub) through, there are 2 types of star type which connects each equipment in the connected form of Ethernet. In addition, with maximum transmission distance and transmission speed etc it divides into several types.

The thin coaxial cable (Thin coax) it utilized 10BASE-2 in the cable, transmission speed 10Mbps, maximum transmission distance 185m, maximum connection equipment several 30 bus types LAN. The thick coaxial cable (Thick coax) it utilized 10BASE-5, transmission speed 10Mbps, maximum transmission distance 500m, maximum connection equipment several hundred bus types LAN. As for 10BASE-T which is utilized most widely, from twisted pair line (UTP) the transmission speed 10Mbps which is utilized, star type LAN to of maximum transmission distance 100m. Multi-stage connection of the hub is to 3 stages.
