SIWES Project in Computer Science Essay

1.1 Overview of SIWESSIWES refers to the employment of students nearing on a lower floor-graduation in firms or organizations, which operate on activities associate to the respective students major subjects.The course, CSC 3299 as offered in Ajayi Crowther University is a compulsory subject offered by every computer science student in the 2nd semester of the third academic year with the prey of enabling students to come into contact with real life applications regarding the k like a shotledge and skills gained in both hypothetical and interoperable courses of the university.The core courses of Computer Science offered by ACU are both theory and laboratory practical -based and instigate in providing a theoretical concept or base to the students so that they are equipped with ample knowledge for joining the work force after completion of under-graduation. SIWES on the other hand helps the students inform themselves with the experience of being employed in their field and effect ively learning and applying the knowledge required by harbouring out their activities in the offices and fields.1.2 Objectives of SIWESThe general objectives if SIWES are outlined as followsHelping students break free from the theoretical world of ****books and class courses and leap into the real world of applications of knowledge.Enabling the students to effectively interact in a work environment within 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 communicate and operate under pressure, if required.To help students enhance their creativity and efficiency in dealing with projects colligate to their field of study.To enable students to pick up skills from the experience and projects of other employees to apply in their own tasks.To enable the student r ealize their relative strength in a field with many practical applications and help students come out with final year projects that model real life perseverance challenges.2.0 Origin of the ReportThis report has been prepared as a requirement of the internship program. The report was based upon the ICT plane section of the organization Nigerian civil melodic phrase authority (NCAA).2.1 ORGANISATION BRIEFS AND STRUCTURE OF NCAABrief Nigerian Civil Aviation Authority is the regulatory body for aviation in Nigeria. It became autonomous with the passing into law of nature of the Civil Aviation consummation 2006 by the National Assembly and assent of the President, Federal Republic of Nigeria. The Act not only empowers the Authority to regulate Aviation Safety without political interference, but overly to carry out Oversight functions of breedports, Airspace, Meteorological Services, etc as well as economic regulations of the industry.Nigeria has just successfully passed through with(predicate) the ICAO Security follow-upAudit of May 2006 and the ICAO Universal Safety Oversight Audit in November 2006. Nigeria is now preparing for the American FAA IASA Category1 Certification.With over 25 Airports, 30 Airlines, 590 Pilots, 19 Flight Engineers, 258 Air duty Controllers(ATC), 677 Aircraft Maintenance Engineers, 1103 Cabin Crew and 4 Aircraft Dis goers, Nigeria now boasts of improved aviation infrastructural facilities at the Airports, state of the cheat navigational aids, modern weather forecasting equipment and highly skilled manpower to ensure safety and ottoman of the flying public. Airlines have started bringing in brand new aircraft to the industry 737-700 new generation, Regional rave CRJ 400/900, 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 theatre director 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 domain and the other data traffic.. Anyone in a domain can communicate with each other and out bound, however PCs not defined in the domain can not communicate with those in the domain. Basically t he network starts from when the broadcast in space sends radio signals down to the satellite dish telephone receiver (ku-band, ka-band, c-band e.t.c). This satellite dish receiver is connected 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 gateway 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 excessively 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 updates and downloading of update for all workstation in the domain with a specific antivir us used for the network installed on them. The ISA server is also connected to a 24 port switch which is connected to the different switch storage locker in each directorate of office buildings (since it is a 24 port switch it take a level best of 23 directorates, another switch can be connected to the first switch in guinea pig of more buildings). Ever building has a cabinet where LAN (local area network) connections are distributed to different offices. The cabinet comprises of switches and patch impanels.The patch panel is a device 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 intimate 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.
