1.1 Overview of SIWESSIWES refers to the transaction of assimilators nearing chthonic-graduation in firms or sensibleations, which work on activities related to the respective students major unfasteneds.The course, CSC 3299 as offered in Ajayi Crowther University is a compulsory subject offered by every computer science student in the second semester of the third academic year with the objective of enabling students to come into refer with real tone applications regarding the friendship and skills gained in both theoretical and applicatory courses of the university.The core courses of Computer Science offered by ACU ar both theory and laboratory practical -based and aid in providing a theoretical model or base to the students so that they are equipped with sufficient knowledge for joining the work force after completion of under-graduation. SIWES on the new(prenominal)wise hand serve wellheads the students familiarize themselves with the experience of being employ ed in their dramatic finesse and effectively learning and applying the knowledge required by carrying out their activities in the offices and fields.1.2 Objectives of SIWESThe general objectives if SIWES are outlined as followsHelping students break complete from the theoretical world of ****books and class courses and leap into the real world of applications of knowledge.enable the students to effectively interact in a work environment at heart a hierarchy of employees. The efficiency in working in groups and under higher authorities is tested during this course.Helping students to express dependability, initiative, resourcefulness and professionalism in the tasks they are assigned.To evaluate the persons ability to progress and operate under pressure, if required.To help students enhance their creativity and efficiency in relations with projects related to their field of study.To enable students to pick up skills from the experience and projects of other employees to apply i n their own tasks.To enable the student realize their recounting strength in a field with many practical applications and help students come out with final year projects that model real life industry challenges.2.0 Origin of the Re interfaceThis report has been prepared as a requirement of the internship program. The report was based upon the ICT department of the organization Nigerian cultured aviation authority (NCAA).2.1 ORGANISATION BRIEFS AND body structure OF NCAABrief Nigerian Civil Aviation Authority is the regulatory body for aviation in Nigeria. It became autonomous with the passing into law of the Civil Aviation Act 2006 by the National Assembly and assent of the President, Federal Republic of Nigeria. The Act non only empowers the Authority to regulate Aviation Safety without political interference, only also to carry out Oversight functions of Airports, Airspace, Meteorological Services, etc as well as economic regulations of the industry.Nigeria has just successful ly passed through the ICAO Security revaluationAudit of May 2006 and the ICAO Universal Safety Oversight Audit in November 2006. Nigeria is now preparing for the Ameri dissolve FAA IASA Category1 Certification.With over 25 Airports, 30 Airlines, 590 Pilots, 19 Flight Engineers, 258 Air Traffic Controllers(ATC), 677 Aircraft Maintenance Engineers, 1103 Cabin pack and 4 Aircraft Dis topographic pointers, Nigeria now boasts of improved aviation infrastructural facilities at the Airports, state of the art navigational aids, modern weather forecasting equipment and highly skilled hands to ensure safety and comfort of the flying public. Airlines have started bringing in brand new aircraft to the industry 737-700 new generation, Regional Jet CRJ cd/900, Dash 8-400Q, Business Jet/Turboprop, Helicopters, B777, Dreamliner B787, Jumbo Jet Boeing 747-400 series as well as brand new Regional Jet Embraer.3.0 NCAA STRUCTURESenior Management handler General Dr. H.O.

Domains are groups of PCs on the same network and are a method to isolate communications between the members in the land of a function and the other data traffic.. Anyone in a domain poop communicate with each other and out bound, however PCs not defined in the domain can not communicate with those in the domain. Basicall y the network starts from when the satellite in space sends radio signals down to the satellite spectator receiver (ku-band, ka-band, c-band e.t.c). This satellite dish receiver is attached to the private port of the internet modem then the public port of the modem is connected to the ISA server which acts as the gate appearance to internet access. The ISA server is connected to a domain controller which controls the domain environment by granting anyone who has a registered account on the domain access to the internet recourse. I.e. anyone who does not have an account or valid log on credentials cannot use the internet.Domain controller can also be used to control the network environment by restricting the rights to chance setting on the workstation so that only administrative rights can alter settings. The ISA server is also connected to an antivirus server which monitors the automatic rifle updates and downloading of update for all workstation in the domain with a specific an tivirus used for the network installed on them. The ISA server is also connected to a 24 port renewal which is connected to the different switch cabinet in each directorate of office buildings (since it is a 24 port switch it take a maximum of 23 directorates, another switch can be connected to the first switch in case of more(prenominal) buildings). Ever building has a cabinet where LAN (local area network) connections are distributed to different offices. The cabinet comprises of switches and patch panels.The patch panel is a catch that is used as a repeater so that signals dont get loss over a long cable. One of the cables that comes from the main 24 port switch goes to the patch panel then a RJ-45 cable is connected from the patch panel to the switch (mostly a 24-port switch) in the cabinet (in case of two switcheswe have two patch panels.). The patch panel then distributes the connection in the office or to other offices in the building as LAN port where workstations can be connected to by the use of RJ-45 cable (workstations can also be connected directly to the switch). As for wireless connection, a wireless router or access point is placed at every passage way in each building. The wireless access point is either connected to one of the switches in the cabinet or the main 24-port switch.
