A customized Server-Based Computing Solution can reduce the cost of desktop computing. A solution that should not be overlooked in your IT strategy is the Server Based Computing approach which delivers critical business applications to end-user devices through the use of Thin Client computing technology.
With this approach, it doesn’t matter if the client device is a full-featured PC, a Macintosh system, a UNIX workstation, or a true thin client device like a Windows-based terminal or hand-held (wireless) information appliance. With server based computing solutions, all of the applications and data reside and execute on the server.

Server Architecture
The cost of desktop computing can be reduced by this computing approach. Application installations, updates and additions are made only once on the server and after that, they are instantly available to all users anywhere, with exceptional performance. Applications can be managed by the IT professionals on the network from a single point and also provide enterprise-level security for data and applications.

Virtualization technology allows customers to run multiple operating systems concurrently on a single physical server, where each of the operating systems is running as a self-contained computer.
There are many situations whereby users have a legacy application which they want to move natively to Windows Server 2003 or plan to end-life that application which is running on old hardware.

If you want to upgrade that hardware to run Windows Server you can put a Virtual Server on it and run that legacy application on a legacy machine and have the flexibility of upgrading on your own schedule.

Usage Scenarios for Virtual Server is designed for running enterprise server operating systems and applications.

Some scenarios for using Virtual Server include the following:
Server Testing
Virtual Server can be used in situations that require rapid and frequent server reconfiguration. For instances, you can use it for development and testing, product demonstrations, or training.

A library of virtual machines can be created in different server configurations without the need to dedicate a physical computer to each configuration.

Your virtual machines can be easily deployed from this library with a few clicks of the mouse. Virtual machines can be set up to use undo disks as the changes can be discarded, or differencing disks can also be used to create a variety of configurations from one base disk. This is useful especially in situations where you have to test software or certain software configurations before you actually deploy them.

This approach is useful for you if you need to test the effect of a software update before deploying it to your organization. In addition, you can quickly create virtual networks that simulate physical networks. After that, you will be able to test real-world scenarios in your virtual network.

Server Consolidation
Many companies have departmental and branch office servers that are underutilized because different departmental or branch office applications were written for different operating systems or different versions of the same operating system.

You can migrate these applications and operating systems into virtual machines running under Virtual Server on a single physical server in order to reduce the number of physical servers you maintain.

Application Migration
Many companies have server applications that require an older operating system, such as Microsoft Windows NT® Server 4.0.

Upgrading to a newer, more resilient system would require rewriting the applications. However, this can be very costly. Moving older operating systems and server applications into virtual machines running under Virtual Server and a Microsoft Windows Server 2003 operating system would be a more cost-effective and manageable approach.

Basic File Architecture
 The same file types for configuration and resource files are being used by both virtual pc and virtual server. For example, virtual hard disk files are .vhd files, saved state files are .vsv files, and virtual machine configuration files are .vmc files . Virtual machines (within certain limitations) are allowed to be shared between Virtual PC and Virtual Server by this common file architecture .

Networking
Both virtual pc and virtual server allow networking between virtual machines and physical machines. With Virtual Server, however, virtual networks can be created and configured.

Virtual machine control options.
Both virtual pc and virtual server have the same options for controlling virtual machines, such as starting, stopping, shutting down, and saving state.

Disk features.
Undo and differencing disks are available in both Virtual PC and Virtual Server.

A local area network (LAN) is a group of computers and associated devices that share a common communication line and also the resources of a single processor or server within a small geographic area (for example, within an office building). The applications and data stored in the server are usually shared by multiple computer users.

A local area network may serve only two or three users (for example, in a home network) or as many as thousands of users (for example, in an fddi network).

The main local area network technologies are:
Ethernet
The most widely-installed local area network (LAN) technology is ethernet. Specified in a standard, IEEE 802.3, Ethernet was originally developed by Xerox before being developed further by Xerox, DEC, and Intel.

An ethernet LAN typically uses coaxial cable or special grades of twisted pair wires.
Ethernet is also used in wireless LANs. 10BASE-T are most commonly installed Ethernet systems and  transmission speeds of up to 10 Mbps are provided

Devices are connected to the cable and access is competed using a Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol.

With transmission speeds up to 100 megabits per second being provided, fast ethernet and 100BASE-T are typically used for LAN backbone systems, supporting workstations with 10BASE-T cards.
Gigabit ethernet provides an even higher level of backbone support at 1000 megabits per second (1 gigabit or 1 billion bits per second).10-gigabit ethernet provides up to 10 billion bits per second.

Token Ring
A token ring network is a local area network (LAN) in which the all computers are connected in a ring or star topology and a binary digit or token-passing scheme is used in so as to prevent the data between two computers that want to send messages at the same time from collision.

After ethernet, the token ring protocol is probably the second most widely-used protocol on local area networks . The IBM Token Ring protocol led to a standard version, specified as IEEE 802.5. Both protocols which are very similar are used.

The IEEE 802.5 token ring technology provides for data transfer rates of either 4 or 16 megabits per second.

Very briefly, here is how it works:
Empty information frames are continuously circulating on the ring. When a computer has a message to send, a token is inserted in an empty frame (this consist of simply changing a 0 to a 1 in the token bit part of the frame) and a message and a destination identifier is also inserted in the frame.

Each successive workstation then examined the frame.If the workstation is the destination for the message, the message from the frame is copied before changing the token back to 0.

Seeing that the token has been changed to 0 and that the message has been copied and received when the frame gets back to the originator, the message is then removed from the frame. The frame continues  circulating as an “empty” frame, ready to be taken by a workstation when it has a message to send.

The token scheme can also be used with bus topology LANs. The standard for the token ring protocol is Institute of electrical and electronics engineers (IEEE) 802.5. The Fibre Distributed-Data Interface (FDDI) also uses a token ring protocol.

Arcnet
ARCNET is a widely-installed local area network (Lan) technology which uses a token-bus scheme for managing line shared among the workstations and other devices that are connected on the lan.

The lan server circulates empty message frames on a bus continously (a line in which every message goes through every device on it and a device using only those with its address).

Whenever a device wants to send a message, it inserts a “token” (this can be as simple as setting a token bit to 1) in an empty frame in which the message is also inserted.

The token is reset to 0 when the destination device or lan server reads the message, so that other devices can reuse the frame again.

The scheme is especially efficient when traffic increases as all devices are afforded the same opportunity to use the shared network. ARCNET can use coaxial cable or fiber optic lines.

FDDI
FDDI (Fibre Distributed Data Interface) is a set of ANSI and ISO standards used for data transmission on fibre optic lines in a local area network (Lan) which can extend up to 200 km (124 miles) in range. The FDDI protocol is based on the token ring protocol.Besides being large geographically, an FDDI local area network is able to support thousands of users. FDDI is usually used as the backbone for a wide area network (WAN).

An FDDI network contains two token rings and in case the primary ring fails, the other can be used as a backup. The primary ring offers up to 100 Mbps capacity. If the secondary ring is not needed for backup, it can also carry data, extending capacity to 200 Mbps. The maximum distance can be extended by a single ring; a dual ring can extend 100 km (62 miles).

FDDI is a product of American National Standards Committee X3-T9 and conforms to the Open Systems Interconnection (OSI) model of functional layering.It can be used to interconnect lans using other protocols.

The capability to add circuit-switched service to the network so that voice signals can also be handled is added in FDDI-II, which is a version of FDDI.

A suite of application programs can be kept on the lan server and users who need an application frequently can download it once before running it from their local hard disk.

Through the applications running on the lan server, users can order printing and other services as needed. While a user can share files with other users at the lan server; the read and write access is maintained by a lan administrator.
A lan server can also be used as a Web server if there are safeguards taken to secure internal applications and data from outside access.

A wide area network (wan) is a group of devices located remotely and connected through some electronic means, i.e. telephone system, satellite link, etc.
What this actually means is a large group of computers linked together via hardware and software in an unlimited area.

This network may be across town, between cities or between continents. The network normally has one or more lans containing servers for file and print applications, printers for document output and a number of workstations for the end users.

All of these resources are normally physically connected  via some form of cables (i.e. coaxial, twisted pair, etc.) to a hub and/or router before being connected to a telephone system, satellite link or other form of electronic transmission. The key word is unlimited, the network becomes a lan when computers are connected locally.

Allowing an organization to share data and hardware throughout all its locations so as to maximize the company’s data processing investment is the purpose of a wan.

Ideally, the WAN should improve the following:
- Communications/Productivity of Employees
- Information management
- Reduction/control of costs
- Standardization of hardware/software usage
The WAN should be transparent to the user and also manageable by network professionals.

Nas servers eliminate server I/O (Input/Output) bottlenecks to enhance network performance. LAN clients access these devices over standard network protocols such as TCP/IP and files can be shared simultaneously across different protocols such as CIFS, NFS and HTTP, which means they are server and operating-system independent. This makes it easy for system administrators to add, maintain, and access large amounts of storage capacity.

Nas systems are not just limited to read/write disk systems, but also include optical media systems such as CD-ROM and DVD-ROM servers.

Besides the basic file service, NAS can also be used for specialised tasks such as e-commerce, web caching, local storage, remote storage or caching in a Hierarchical Storage Management (HSM) environment. NAS servers are engineered for high performance as they are designed from the ground up as storage devices.

An enclosure, power supplies, cooling fans, network connection(s), hard disk drives, a backup device and a scalable controller are included in a  basic disk-based read/write NAS system.

NAS systems can be designed around nearly any operating system, from embedded real-time operating systems to Linux or compact operating system kernels that are optimised for file serving.

The tasks include managing the network connections, accepting file requests, sending and receiving data from the disk drives, returning data to clients and monitoring the overall health of the system.

Key Benefits
NAS brings ease of use to shared networked storage. NAS devices are as easy to add to a LAN as a PC or a printer.

Storage can also be added when needed without disrupting the network, eliminating downtime associated with server-attached storage.

NAS devices are plug-and-play ‘appliances’. The Set-up only requires connecting to the network, applying power, and performing a few mouse clicks.

As the fully integrated hardware and software are provided by NAS configurations, they are less complex to use than typical general-purpose network servers.

Performance. NAS systems off-load data from the network backbone by providing storage to a workgroup or a department on an independent, but connected, subnet or network division.

NAS separates file-serving services from application processing which is unlike Server-Attached Storage(SAN). NAS servers are not burdened by application function overhead, which improves the overall effectiveness of both the NAS and the LAN.

The application server is faster and the likelihood of a system crash is also lessened. In order to  automate backup functions and eliminate LAN backup traffic, administrators can use NAS-integrated tape devices.

For software projects, according to the Standish Group, 31% of the projects are cancelled evn before the product is delivered to the customers, while 53% cost 189% or more of their original budgets. 40-60% of the software defects and failures are being attributed to poor requirements, thus reflecting the extent of the problem and the need to identify, communicate and manage software project requirements. That is why we at Networkz IT Solutions view the software requirement specification of any software project both large and small as a critical factor.

A software requirements specification is critical in order to understand the goals of the organisation and its customers and the transforming these goals into potential functions and constraints applicable to the development and evolution of products and services. Understanding the relationship between goals, functions and constraints in terms of the specification of products, including systems behaviour, and service definition are involved.

The motivation for programmes and projects are provided by the goals and they represent the ‘why’ and to a certain extent the ‘what’ in development terms. The specification provides the basis for requirements analysis, validating that they are indeed what your business stakeholders want, defining what needs to be delivered, and verifying the developed software product.

Establishing a common understanding between your business and Networkz is the aim of a software requirements specification so that all requirements can be addressed at an early stage in the project life-cycle and maintain control by establishing suitable base-lines for both development and management use. In short, a software requirements specification allows your business to know exactly what will be delivered, how it will be delivered and in what time frame.
