Introduction In the Graduate Institution of Education they use various sorts of computers for many different things. A lot of staff uses their personal computers for keying in long paperwork or words; others may use them for creating PowerPoint demonstrations for lectures. In most organisations people will use their computer systems for similar things, although this isn’t the case in a university.
Machine Hardware There are a number of computers, and these all do different jobs. Every server is allocated a name, which is unique above the whole campus. Most of the main file computers are kept within the laptop centre. This enables them to rectify any conditions that may come up if a hardware fails. All the main computers work on dual hardware, and are hot swappable.
This means that in the event one cpu fails, or perhaps if one particular Random Get Memory position fails, they can replace it, with no down time. The only time the server would venture down would be in the case of a Power Supply Device failing, which is fixed within minutes. Inside the computer middle all the personal computers are attached to a UPS and spike protection, as sockets surrounding the centre. The surge security will stop computer components getting damaged because of a surge on the nationwide grid, as well as the UPS will need over if you have a electricity cut. The UPS provides power to the servers inside the computer center for a considerable amount of time.
The smaller servers almost all have a tiny UPS, and these are designed to shut the server down if the electrical power is off for almost any longer than 10 minutes. This means that all unsaved files happen to be saved towards the hard disk. Inside the Graduate University of Education there are 5 small computers, and these all do distinct jobs. There are 2 site controllers.
The primary one is known as Charlie as well as the backup is referred to as Bravo. In addition there are 2 Macs database machines. One is a Mac G3 and the various other is a PowerMac.
In the main computer system centre you will find too many machines to mention right here, and they are not every related to the Graduate School of Education. The ones they will use will be the Student record server as well as the Library hardware. Both of these servers run on a telnet hardware (on port 23), which allows safeguarded access to all of them from inside the grounds. Domain Controllers All departments in the university or college have their individual domain remotes.
Domain remotes are usually rented or let to people by simply domain name hosting companies. This sometimes has an advantage, if anything goes wrong, their very own technical support personnel will correct the problem, in a university or college there are plenty of competent people that can function with domain name controllers. Mainly because all the site controllers will be kept on grounds, if JANET was to go down for some reason, for instance , the cable television was dug up; all of the university fields would nonetheless work. Therefore , a clumsy honnetete person will not check that the location they will be digging in is apparent of cables, and they begin work.
They hit the fibre optic cable as well as the university’s Web connection goes down. They may still be able to head to any of the college or university domains, for example , http://www.edu.qub.ac.uk or http://www.qub.ac.uk. The university network is fairly home reliant in this way. A domain controller does not must be a very quickly or powerful machine, but it is usually just a normal machine. Here is a rough idea of the hardware and price employed in the domain controller: Components Name Cost Full Description File Server Case ï¿½125.

Data source Servers The database machines hold information concerning different things in the department.
The graduate university of education use them pertaining to holding information on students and staff, like addresses and telephone quantities. It is a lot more effective than using newspaper to hold data. The databases servers happen to be Macintosh. They are usually seen as high-priced, useless equipment, but the Macintosh computers are more powerful than the usual conventional PERSONAL COMPUTER, and their primary drawback is that it is difficult to have software for them, and no personal computer software is appropriate for them.
Network The school network is fairly a big program, and could probably be described as a large Area Network, because of its size, although it is very just a substantial Local Area Network. Here is a little network picture showing how a Queens’ Network works. Hopefully from this quite simple diagram you can view how big the university or college really is, and how much it costs for electricity alone every year. Between all the colleges in the United Kingdom we have a shared Web connection.
This is a fibre optic system. There is a slight difference between utilizing a fibre and using copper cables. One particular small dietary fibre can carry up to 1, nine hundred phone calls. This is quite a big big difference compared to 40 over a single copper cable. This means that the computer users in the University will have very fast Internet access, and between other schools, it can be likely to down load a full CD’s worth of data (700MB) in around 10 seconds, and this isn’t with just one user using the network at that time.
The speed of JESSE is quite hard to measure with full accuracy, in fact it is changing in speed every day. Between departments there are also nutritional fibre optic wires, as this allows more data to be transmitted. Once you get into a department the fibre is definitely brought into a hub, and from the link to each computer system you have a copper cable television.
This is maybe not the most efficient approach, but it is significantly cheaper than having a nutritional fibre optic system the whole method around the office. Looking at the diagram above you will see that the Graduate School of Education is a little part of the college or university network. This is the slightly more thorough diagram in the network with this particular section: The network is too significant to show in much more details than demonstrated above. You will discover roughly a hundred and fifty computers from this one office alone, and across grounds there is anything between 2000-6000 computers connected to the network.
They are all connected centrally at the primary Queens’ hub, so coming from anywhere upon campus you could find a route to anywhere else. As well, if for whatever reason the main hub failed, departments would still be able to send data to each other, provided that it would not need to keep the section. Workstations and Software Because the department is usually large, it might be difficult to find two computers which might be the same in hardware specs. Generally all of them are normal, household computers, even though the computer laboratory has desktop cases instead of ATX, This does not really have an effect on how they job. Data can be shared between all the pcs using the public directories, although only employees have access to these types of.
All personal computers are connected to the network using 3Com network cards, working on 10 Mega bits / second. This is the main speed limitation of the network. All work stations have the Microsoft Office Collection which is portion of the Microsoft Office Campus Arrangement, and FrontPage and Publisher have a different license for many departments, as these are not section of the campus contract as a whole. There is also a copy of Symantec Anti-virus, which is up to date through the Symantec server, and this provides up to date virus safety.
Staff have access to Adobe PageMaker 6. your five and Macromedia Dreamweaver. Application Specification This is the more detailed go through the different computer software that the Institution of Education use. * Microsoft Expression – It has many uses. Some personnel may use that to type letters and notices; a lot of may use that for keying in assignments or taking mins from a meeting; students may use it for its desktop submitting ability or for typing up coursework/essays. * Microsoft company Excel – This is Microsoft’s spreadsheet software and is found in many ways also.
Some personnel may use this to keep track of students’ progress; several may use this to keep track of outgoing and inbound money; learners may use that to create graphs. * Microsoft company PowerPoint – This can be utilized for many things too. Some lecturers would utilize it for creating transparencies for lectures, but in this kind of high-tech age it would be more likely for them to put it to use in conjunction with searching for projector. There are numerous of these open to staff in the daytime. Students may sometimes use it for revision purposes, or perhaps for glide shows in class participation exercises. * Microsoft company Publisher – This is utilized for desktop submitting and creating transparencies pertaining to lectures.
2. Microsoft FrontPage – This is Microsoft’s web design software program. It is often used by lots of professional designers, but will not really have a use in the training department. * Microsoft Access – This is Microsoft’s database package, in fact it is very versatile. It can be used to develop macros in order that on a click of a button you can enter in large amounts of data into a database or delete old documents. The macros are easy to software using Ms Visual FUNDAMENTAL. * Macromedia Dreamweaver – This is specialist web design software used by many top end professionals. It includes the capability to write many different programming languages suited for web web servers.
It may cost countless numbers to acquire that kind of software created. They often use many different programming languages, generally C++, which can be very advanced and can take several years to learn. Since the university does not have many departments which often exactly the same point, database software designed exclusively for the university or college would cost too much, and probably push student costs up a significant considerable amount. Frequently Microsoft Get is more than enough to fulfil the needs of the departments needing databases. Different Hardware There are numerous hardware equipment in the school.
The most expensive could possibly be the digital cameras and projectors, and these might take some time to replace if they are ruined. The cheaper devices just like mice, input keys and drive drives are often replaced, and there are many extras in the college or university. There are many different types of computer printers available, usually mono colour laser printers and shade ink aircraft, but there are some colour lazer printers obtainable. Printer ink cartridges are replaced when needed, and therefore are purchased with discount, as they are in huge numbers.
Code readers are available in laptop rooms for student work with.
