1. Introduction
Any Company Corporation is a small Corporation and it does not contain any IT Department. The systems are still running under Windows 7 Operating System (Microsoft.com, 2017) and there is a low capacity, monochromatic laser printer attached with each system which is not sufficient for video development. The two partners and the office manager all have older PC computers. These things will not support the video development and other interactive media. The office must be reorganized and additional resources must be added to enhance video development. The company should have employees from different fields to ensure best video development and marketing. Some of the additional employees to be added are:
a. Administrative manager
b. Film and Graphics Production Editor
c. Film Crew
Mobile workers are also equally important as they are easily accessible to the main workers. They work at various locations and they must be able to connect to the main works wirelessly to store files. A private colour laser printer must be installed in manager’s office and scanner should be there to establish communication between the employees of the organisation.
Any company Corporation is an advertising company. They are planning to improve their business. They are planning to update their IT infrastructure (Taylor, 2017). The existing IT infrastructure will be studied. Existing applications and their hardware requirements will be investigated. The customer requirements will be taken with the help of interviews with various application end users in the customer place. Their budget will be taken into account. The new computer systems will be found out from the market based on the technical requirements of the various end users. Suitable high speed printers will be identified based on the end user requirements and the available printers in the market. Various ISPs will be investigated and suitable ISP will be selected for the updated IT infrastructure. The internet connecting services will be identified. All the network planning will be done and will be documented as network planning form. It installation planning will be done. Suitable IT floor plan will be drawn with suitable network drawing software. Suitable network and file security plan will be drawn for the customer.
2. End User Requirements
End user requirements (Hassan, 2013) are taken first. There are eight employees in the office - two main workers and six mobile workers. Fred Michaels and Roberts are the workers who are available in regular hours. They can communicate with the mobile workers through email provided by ISP. The employees can share even from their home and they can send from a range of small to large size data files. The company also has six to eight temporary employees who work from their home and use their own computers. When the mobile workers are in office, they can make use of printers and scanners to get ready with the video.
First of all, it is mandatory for any organization to do the task with the specified budget. The organization has to exhibit different levels of project evaluation.
Some of them are:
1. Computer System Planning
It involves the cost of processor, memory, hard drive, video card, USB, DVD.
2. Select a high-resolution colour copier/printer.
3. Network layout must be chosen such as home network or small business network.
4. Planning the internet connectivity and ISP services. Select a local ISP for DNS and web mail. The ISP must provide 99.99% uptime access to the network.
5. Choose internal services and devices.
6. Various factors should be analysed like wired connections, wireless connections, ISP connectivity, modem, cable, battery backup.
7. It is a mandatory step in any organization. Installing the system at correct place, correct order matters a lot to the growth and efficiency of the company.
8. Physical layout must be presented
9. Addressing schemes must be provided so that all the hosts in a network gets a static address.
10. The most important step is to provide security to the files that are used in the network.
In order to make AnyCompany Corporation lucrative, the details given in the report should be followed for the successful future of the organization.
3. Project Proposal
System Requirements for a Small Office
A standout amongst the most imperative parts of any business nowadays is a PC arranges which permits client records, documents and other data to be shared effectively. Obviously, computerization of the workplace is just the same old thing new, yet in the web age it is near on fundamental that a system isn't useful for the workplace laborers who will utilize it, yet for clients who need to get to it, through web applications for example. Be that as it may they should do this while giving the correct level of security from digital dangers and from data being improperly gotten to. Despite the fact that a system is surely an empowering innovation so far the same number of little workplaces are worried, there are likewise entanglements to be evaded. Little office directors need to take these components into thought the same amount of as those running expansive ones do (Opsview.com, 2017).
A Single Small Office
For little and medium undertakings (SMEs), a system does not should be anything exceptionally fabulous. Most office specialists will require a PC and - in most set ups - it is least complex to outfit all the staff with either comparably indicated PCs or Macs. A run of the mill arrange that a SME will use, will have work stations for all staff to get to a focal database where records are hung on another machine - called the server. By utilizing the customer and server framework, records can be refreshed, perused and changed without causing potential issues caused by various clients getting to similar records in the meantime. The server takes control and will just enable one individual to roll out improvements, subsequently maintaining a strategic distance from clashes and information debasement (Opsview.com, 2017).
Ordinarily, a progression of PCs interfaces with a server over a neighborhood, or LAN. LANs are usually made with organized cabling associating every terminal to a switch or an exchanging switch. In basic terms, a change transmits information to and from servers and terminals by means of Ethernet link and just the PC that is asking for the data ought to get it. In any case, in little workplaces - where there are not that numerous PCs and where the requests of the measures of information being passed in reverse and advances are not that extraordinary - a remote LAN is likewise utilized. This implies marginally slower working, yet less cabling and startup costs. In some little workplaces a mix of a conventional Ethernet LAN and a Wi-Fi remote one is utilized. Remote LANs offer a lot of adaptability since cell phones - like tablets and portable PCs - can get to the system from anyplace in the workplace. This implies staff can move around starting with one work area space then onto the next.
Access to the outside world, by means of the web is another capacity of the system. A switch which can have numerous gadgets interface with it is known as an exchanging switch and these are normally utilized by SMEs to give web access and an unobtrusive system ability. Promote servers are required to run things like printing administrations and email conveyance, however these can generally be joined on a similar machine.
Little Branch Offices
Where a little office set up is a piece of a bigger association, the LAN may likewise need to interface with the principle organization's system, maybe in another area in the nation, or even abroad. Alongside the little LAN set up examined, this ordinarily implies a private system association with the primary servers somewhere else.
There are two guideline ways that little workplaces interface with their bigger, parent ones. Rented lines can be employed from a system administrator and they make a physical association between the two destinations. Frequently minimal more than advanced telephone lines these are leased and give a shut - or private - organize which is generally very secure.
Virtual private systems are the other choice. These utilization web conventions to impart information between destinations for all intents and purposes. Bundles of information are sent and got between servers at the two finishes of the system over the web - or cloud as some call it. This implies albeit private information is sent over an open system that it ought to stay secure, insofar as abnormal state of encryption is utilized.
Information Protection
Nowadays, even little workplaces need to consider information insurance issues important. Indeed, even the loss of little measures of information can arrive organizations stuck in an unfortunate situation and they can have a genuine effect on an organization's notoriety. Information encryption over the web ought to be taken care of by the gadgets that give these administrations, however very regularly office supervisors disregard the prerequisite of clients working at terminals to protect the information. This implies setting passwords and transforming them frequently. At times, where there is touchy information, some staff ought to have certain confinements put on what they can read from their work station. Alongside the innovation, office laborers require sufficient preparing with the goal that they know about the issues encompassing information insurance, such as locking their PC on the off chance that they step far from their work area.
1. Floor Plan
Floor plan can be drawn for existing office or new improved big office. The sample floor plan is given below. Entire office is divided into various departments and manager got separate room. Servers will be kept in servers room as the room temperature for keeping the servers will be around -9 degree Celsius. Each department can have separate rack in which the switches, hubs and other network devices can be installed. If that department got its own file server then that server too can be installed in the local rack.
