Life in a modern technologhy requires skills in dealing with computers...CH 8
Network Management.

8.1 Network Documentation.
*Cut sheet diagrams.
The first and most critical component for a good network is documentation. Documentation is the most talked about and least performed task in a network.
diagrams that indicate the path of the physical wiring layout;
the type of cable;
the length of each cable;
the type of termination for the cable;
physical location of each wall plate or patch panel, and;
A labeling scheme for easy identification of each wire.

* MDF and IDF layouts
This is a Physical and logical layout of the Main Distribution Facility and all of the Intermediate Distribution Facilities in the network, layout of rack mounts, auxiliary equipment, and servers in the distribution facility, patch panel labels to identify cable terminations. Identification and configuration details of all equipment located in the distribution facility.
   
*Server and workstation configuration details
This is any physical detail of the computer, model and serial number, Physical location, user, and network identification.

*Software listings
Standard and special software used on each machine in the network.
This list includes operating system and application software.

*Maintenance records
It is also valuable to keep a list of all repairs that have been done to all equipment included in the network. This will help an administrator predict possible future problems with existing hardware and software.

*Security measures
Includes "soft" security, such as user rights, password definition, and firewall support, but also physical security. Physical or hard security includes things as simple as identifying how the MDF and IDF's are locked, who has access to these rooms and why, how the hosts are protected (security cables - alarms), and who has physical access to the system.


*User policies
They contain how the users can interact with the network. These policies include what is and what is not permissible on the network. It should also include what the consequences of violating user policies will be. Other aspects of user policies include what minimum user ID and password length should be, and rules for the content of passwords.


8.2 Network Security includes the following.

* Network access
It involves making the network as secure as possible against unauthorized access. This is done by establishing security policies, such as minimum password length, maximum password age, unique passwords (not allowing the same password repeated), and only allowing the user to logon to the network at particular times of the day or days of the week. Security also involves making sure that users are aware of the company's network policies and follow those policies.


*Data recovery.
The second part of network security involves protecting data from loss.
Three popular data protection methods are Tape Backup of data, fault tolerant disk configurations, and the use of uninterruptible power supplies

* Back up operations
1. Full backup: All files on the disk are stored to tape and the archive bit for all files is set to off.
2. Incremental backup: Backs up all the files that have been created or modified since the last full backup. It is important to remember two things about an incremental backup. One, that it only works in conjunction with a full backup and two, which any file created or modified has its archive bit turned back on so it will be saved to tape during the next incremental backup.
3. Differential backup: Backs up all the files that have been created or modified since the last full backup. This sounds the same as an incremental backup, but the difference is that even though the file is saved to tape, the archive bit is not reset. This means that each time a differential backup is done, all of the files modified or created since the last full backup will be stored again.
4. Copy backup: Backs up user selected files to tape. This backup also does not reset the archive bit to off.
5. Daily backup: Backs up only the files that are modified on the day of the backup. This backup also does not reset the archive bit to off.

*Redundancy techniques
There are other RAID levels but they are beyond what is needed for the level of understanding we need. In fact not all network operating systems support ... more

The society in which we live is complex and sophisticated.  As consumers we demand a variety of goods and services to enable us to maintain the quality of life we enjoy. In order to satisfy these demands, suppliers must produce the goods and services, which the consumer wants by combining factors of production such as land, labour and capital in the most efficient manner. To do this the hiring of workers, rent or purchase of the appropriate premises, and maybe, even investing in plant and machinery, as well as the raw materials needed to produce the final product.  These are just some of the factors that have to be considered before the final product is produced at a profit.  This is achieved under commercial organisations.  In short, an organisation is a group of people working together to achieve a goal of supplying a demand.  In Britain, the economy is made up of the Public Sector and the Private Sector.
The Public Sector Company provides goods and services through the state in much the same way as commercial organisations.  This sector also employs staff, occupy premises and raise capital. The public sector seeks to fulfil a service such as education, hospitals, police, etc.  These services are necessary to provide society with order, in which individuals are free to express their demands and producers are able to meet such wants.
The prime objective of the private sector is to make a profit.  These organisations are made up of several different sectors.  They are a mixture of large and small business.
Banks, Railtrack, Imperial Chemical Industries, Solicitors, Accountants.
Sole traders are normally owners of small businesses such as the newsagent or the local cafe.  The sole trader has unlimited liability and has a greater risk than a partnership. However, he has total control of his business and is alone in the making of all decisions relating to his business. The sole trader keeps all profits but in the majority of cases works very long hours, it is also very hard to find the time for things such as holidays.  
Partnerships has a minimum of two people and no more than twenty partners, who have made an agreement to work together and to provide capital for the benefit of the company. Their aim is to make a profit. These businesses are normally on a larger scale.  Sleeping partners in the business i.e. profit share partners do not play an active role in the organisation.  A Deed of Partnership is normally drawn up when setting up a partnership.  This sets out the terms and conditions such as the objectives, profits, transfer of ownership, individual salaries, decision-making, etc.  
Private Limited Companies have certain legal binding restrictions before it can trade, these are:
The Memorandum of Association            
This consists of the company relating to the outside world i.e.: name and rules, address of the business, the names of the directors and the purpose of the organisation.
This relates to the internal matters of the organisation. When the Article of Association form in completed it is then registered and permits the company to trade.
A Public Limited Company has similar rules to limited companies with the exceptions:
Shares can be openly bought and sold
A vast amount of capital can be made available through the issue of extra shares.
The minimum share capital required is 50,000.
No limits to the amount of shares a shareholder can have.
The functional areas of an organisation such as a music venue can be vast.  Therefore, the areas that will be dealt with will be limited.
The marketing department is responsible for all publicity that the organisation needs to make public awareness and the events available. They also can organise suppliers, as well as the delivery of these items.  This department is in charge of all venue publicity and public awareness.
The accounts department is responsible for the payment of all bills/invoices.  When an invoice is presented for payment, the manager concerned first checks it against the appropriate delivery note.  Only then, will this department approve payment automatic and regular payments such as, standing orders and direct debits are also done through this department.  These systems of payments are required to pay bills like gas, electric and other suppliers used on a regular ... more
