Advantages of Antispyware Programs

Much like the antivirus programs, now a days anti spyware programs also is a must if you are browsing the net. Most of the antivirus programs provide a good job by taking care of the computer viruses. However, many of them fail to detect the spyware which gets installed onto the PC when connected to the internet. This is where Anti spyware programs comes to help. They do a good job by protecting our computers by identifying the spyware and promptly remove them.

There are so many antispyware programs are available in the market. Both in the Online as well as near to your computer retail showroom. However, you have to ensure that you buy a good Anti spyware program which fulfills the requirements what it promises. Also, make sure to check that the software works on your Operating System. Most of them work on Windows Operating system; however, there is no harm in double checking the same.

Some of the characteristics of a good antispyware program is as below.

Real time scanning

Real time scanning is the heart of these type of programs. The program once installed should reside on your system tray and should be able to do a real time scan in the background. This way it should be able to identify all kinds of threats like Adware, spyware, Trojans and the harmful key loggers.

Automatic Updates

There is no point in having an Antispyware software program which does not update the spyware definitions automatically and at periodic intervals.

Customer Support

Most of the time you will not be require to call up their helpdesk as the software will work automatically provided if the operating system is compatible and all the installation prerequisites are met. However, if you run across any installation problems or some kind of bugs customer service comes in handy.

What Is The Difference Between ERP And Enterprise System?

Enterprise system and Enterprise Resource Planning System terms are similar but there is difference between an enterprise system and an ERP system. An ES or enterprise system is a large scale system which includes packages like ERP and CRM. ERP is a subset of Enterprise System or it can be said that ES is a superset of ERP. It contains a variety of solutions. ES contains applications and packaged solutions which can be directly used in an enterprise. On the other hand ERP system is the automation of the business processes and the solutions are in the form of modules which are designed according to the client’s requirements.

The functions are customized according to the client’s business environment. Enterprise system does not include architecture of other solutions whereas an ERP implementation automates systems using technical aspects. ERP system includes architectures and databases and is client server architecture. The system is server based therefore the consultant needs to be aware of the technical aspect too.

Another difference between an ES and an ERP system is that the ERP is aimed at improving the functionalities of the organization whereas the ES helps to improve the overall maintenance and accuracy. It provides for better solutions and aids in decision making. ES is difficult to implement compared to Enterprise resource planning and even the timeframe needed for implementation maybe more. The overall impact is high but so are the risks involved. If the ES is not implemented in the right manner, it can cause business failure and if implemented properly it can increase the efficiency and profits of the business organization. It is normally required when there is a big drawback in the current procedures and methodologies in the organization and need to be corrected. The company going in for enterprise system needs to be careful while choosing the software and the vendors due to the risk of failure involved.

The difference between an enterprise system and an ERP system is that ERP is mostly used for medium scale companies to big companies and ES is restricted to the big companies. There are many complex functions involved in big companies which cannot be provided solutions for alone by ERP. The role of ERP is restricted when compared to enterprise system because it does not include customer relationship or vendor management.

These applications are needed when the business process is complex and on a big scale. Therefore bigger organizations need to go with ES instead of enterprise resource planning alone. ERP is also an important system to streamline the internal processes but it does not provide for taking care of the external processes. Enterprise system takes care of the end to end business process of organization since it involves other applications also like SCM and CRM. There is quite a lot of difference between an enterprise system and an ERP and it depends on the company whether it wants to go with an ES to streamline the entire process starting from supplying, production and customer or whether he wants to go with an ERP system to streamline the internal process.

How Useful is CAD Software to Engineers and Architects?

The emergence of advanced technology has made people today dependent on machines. Using computers and software, for example, is a very common illustration of this. Computer experts are coming up with more and more software to make more and more jobs easier.

A more specific illustration of this can be found in the modern approach towards engineering and architecture. These days, professionals in these fields use CAD computer software which is a program that allows them to create designs faster, easier and with more accurate measurements. Aside from the convenience that CAD software brings, it also helps put architects and engineers ahead of their competitors. CAD, which can render designs that are two-dimensional or three dimensional, stands for Computer Aided Design and has been in use since 1982.

So how does CAD computer software work? And what does it do exactly to help engineers and architects? The program is actually multifaceted in the sense that there are many ways it can help. To make CAD work will require, however, a careful study of its features and the many ways it can be used. It is rather a complex yet flexible and highly functional program.

This article will not be enough to discuss the various ways that CAD works but pinpointing its advantages could give some very good ideas. One great advantage of CAD computer software is its easy-to-use tools in the creation and alteration of designs. Obviously, this is so much better than the old fashioned way of using a pencil and eraser directly on paper. This method of designing is obviously so much easier and engineers and architects simply have more time to finish other tasks. In other words, high productivity is going to be the main end result of using CAD.

Before the design is actually printed on paper, CAD also allows both the design professional and the client to preview what has been finished so far. Any alterations can be made simply by manipulating the drawing through the use of the software. With CAD, it is so much easier to spot errors because the designs can be rendered exactly as they would be in reality. Hence, modifications can be done even before printing, thus, allowing one to save.

With the tough competition that everyone has to face these days, it is wise to take advantage of new technologies that can help put them ahead in the race. While traditional methods hold a significant part in the history of design, advanced tools such as CAD software should only be welcomed as man’s way of furthering development in a field of expertise that he himself has created long ago.

Why Architectural Drafting Is Common in Architectural Design

For architectural design projects, while there is the emphasis on using 3D models and architectural BIM modeling, the time-tested practice of using architectural drafting and 2D technical drawings is still commonplace in the AEC industry. Architectural drafting has evolved from the drawing board to computer-aided design and drafting (CAD) software programs. Drafting practices help to provide architectural construction drawings that include the technical details of architectural, structural and electrical elements required for the construction of a building. To understand the stage at which architectural drafting takes place, the workflow of a building design lifecycle must be considered.

The basic workflow of an architectural design project starts with the architect creating a conceptual plan which is usually modelled into architectural 3D models and rendered as photorealistic images for marketing and presentation to clients and customers.

Once the conceptual design is approved by the client, the design is then progressed into more detail and shared with other parties such as structural and MEP engineers. The way in which the design is progressed for the ‘design development’ phase by an architect lends itself to two options, either to develop a 3D model with more detail and then create subsequent sheets and details using a 3D tool such as Revit or AutoCAD, or as is still commonplace, to develop the concept design in 2D using more traditional methods. From the conceptual plans provided by architects and engineers, a drafter can convert these designs using CAD software programs to create technical drawings.

Architectural drafting is the process of creating technical drawings which include the floor plan, sections, elevations, detailed drawings and other documents in a construction drawing set (CD Set), which are typically required for the construction of a building.

The difference between Architectural Drafting and Modelling

Architectural drafting refers to creating 2D technical drawings and architectural construction drawings which are mainly used by contractors and consultants on site. Architectural 3D modelling refers to creating 3D models and renders of photorealistic images which are mainly used to present the architectural design for marketing purposes and then progressed from there to create the 2D technical drawings, in effect feeling like an extra stage (the 3D modelling element). The main software used for drafting, to create 2D technical drawings is AutoCAD while modellers use Revit and ArchiCAD to create 3D models and rendered images. Architectural draftsmen need to have basic 2D and 3D software knowledge such as AutoCAD and knowledge of technical codes and drafting guidelines specified by organisations such as American National Standards Institute (ANSI), American Society of Mechanical Engineers (ASME), American Design Drafting Association (ADDA), Public Works Government Services Canada (PWGSC), National Institute of Building Sciences (NIBS), BSI British Standards Institute and Standards Australia Code AS1100. Architectural modellers need to have a deeper understanding of architectural, building and construction concepts and experience with 3D software programs such as Revit and ArchiCAD.

Why Architectural Drafting is still Common in Architectural Design Practices

Architectural 3D models are preferred by architects and designers because they provide a 3D perspective of the conceptual plan of the building; it makes management of project data easier and allows for design changes on the go. However, construction companies that require technical specifications of the architectural project prefer 2D technical drawings and architectural construction drawings because they provide accurate details required for construction, most of the resources involved in construction understand 2D drawings, there are no issues with compatibility of software as compared to when using 3D models and it is a suitable solution to meet the budgetary requirements of a construction project. Some of the reasons why architectural drafting is preferable by several construction companies include:

• Suitable as per construction requirements – In some building projects, 2D technical drawings or architectural CAD drawings are sufficient to complete construction, where additional information that 3D models provide is not required. A construction drawing set (CD set) includes all the floor plans, elevations, sections and detailed drawings required for construction. Technical codes, symbols and other additional information such as the type of material are provided in technical drawings. Therefore, construction companies find 2D technical drawings sufficient to successfully complete construction.

• Availability of technical resources – Not all companies have technical resources to deliver 3D models. While drafting teams are qualified to work on AutoCAD to deliver 2D technical drawings, they may not be qualified to work on Revit to deliver 3D models. In the construction industry, the availability of drafting teams who can provide 2D technical drawings is ample compared to companies that provide 3D modelling services.

• Availability of software – The adoption of new software and practices is gradual and slow in the construction industry. The software used in building projects varies from country to country. Some countries use ArchiCAD and AutoCAD Architecture instead of Revit, therefore leading to the incompatibility of project data. 2D technical drawings in AutoCAD are widely used and compatible making it a preferred option to Revit 3D models.

• Suitable as per cost and budgetary requirements – In most cases, construction companies do not find the need to invest more in 3D models, when drafting solutions provide detailed technical drawings which are sufficient and relevant enough for construction. There is also the added investment in resources that are competent enough to understand and implement architectural 3d models on-site.

While architectural 3D modelling and BIM modelling provide design-related information typically required for architects and designers in the design stage of the building project lifecycle, architectural drafting provides technical drawings that are not just about aesthetics but about high-performance detailing of construction elements. Architectural CAD drawings specifically communicate the design intent and help in the construction of buildings which companies find relevantly sufficient over 3D models. Even as construction companies will need to eventually evolve to combining the use of 2D technical drawings and architectural 3D models until then, the time-tested practice of using architectural drafting and drawing solutions in construction is here to stay.

Wide Area Network (WAN)

Types and Characteristics of WANs

What is a WAN?

There are two prevailing definitions of a Wide Area Network (WAN). The book definition of a WAN is a network that spans large geographical locations, typically to interconnect multiple Local Area Networks (LANs). The practical definition of a WAN is a network that traverses a public network or commercial carrier, using one of several WAN technologies

What are its Main Components?

The main components for a WAN are routers, switches and modems. These components are described below in the hardware section.

CPE – Devices on the subscriber contracts are called customer premises equipment (CPE).
The subscriber owns the CPE or leases the CPE from the service provider. A copper or fiber cable connects the CPE to the service provider's nearest exchange or central office. This cabling is often called the local loop, or "last-mile".

DTE / DCE – Devices that put data on the local loop are called data circuit-terminating equipment, or data communications equipment (DCE). The customer devices that pass the data to the DCE are called data terminal equipment (DTE). The DCE primarily provides an interface for the DTE into the communication link on the WAN cloud.

Hardware

In a WAN you will need various types of hardware components for it to function. The typical items of hardware that you will need in a WAN are:

Router – An electronic device that connects a local area network (LAN) to a wide area network (WAN) and handles the task of routing messages between the two networks. Operates at layer 3, and makes decisions using IP addresses.

Switch – A switch is a network device that selects a path or circuit for sending a unit of data to its next destination. Operates at layer 2, and uses MAC addresses to send data to correct destination.

Modem – Short for modulator / demodulator, a modem that enables a computer to communicate with other computers over telephone lines. Operates at layer 1, where signals are converted from digital to analogue and vice versa for transmission and receiving.

Wan Standards

WANs operate within the OSI model using layer 1 and layer 2 levels. The data link layer and the physical layer. The physical layer protocols describe how to provide electrical, mechanical and functional connections to the services provided by the ISP. The data link layer defines how data is encapsulated for transmission to remote sites.

Encapsulation

Encapsulation is the wrapping of data in a particular protocol header. Remember that WANs operate at the physical layer and the data link layer of the osi model and that higher layer protocols such as IP are encapsulated when sent across the WAN link. Serial interfaces support a wide range of WAN encapsulation types, which must be manually specified. These types include SDLC, PPP, Frame delay etc. Regardless of WAN encapsulation used it must be identical on both sides of the point to point link.

Packet and Circuit Switching

Circuit switching and packet switching are both used in high-capacity networks.
The majority of switched networks today get data across the network
Through packet switching.

Circuit-switching is more reliable than packet-switching. Circuit switching is old and expensive, packet switching is more modern.

General Routing Issues

What is a Routing Protocol?

A routing protocol is a protocol that specifies how routers communicate and exchange information on a network. Each router has prior knowledge of its immediate neighbors and knows the structure of the network topology. The routers know this because the routing protocol shares this information.

Protocol

RIP (Routing Information Protocol) was one of the most commonly used protocols on internal networks. Routers use RIP to dynamically adapt changes to the network connections and communicate information about which networks routers can reach and the distance between them. RIP is sometimes said to stand for Rest in Pieces in reference to the reputation that RIP has for breaking unexpectedly and rendering a network unable to function.

Routing Algorithms

Distance Vector

This type of routing protocol requires that each router simply inform its neighbors of its routing table. The distance vector protocol is also known as the bellman-ford algorithm.

Link State

This type of routing protocol requires that each router maintain a partial map of the network. The link state algorithm is also know as Dijkstra's algorithm.

IGRP

IGRP is a type of distance vector routing protocol invented by cisco used to exchange routing data in a autonomous system. Distance vector protocols measure distances and compare routes. Routers that use distance vector must send all or a portion of their routing table in a routing update message at regular intervals to each neighbor router.

Addressing and Routing

What does routing mean?

Routing is the process of deciding how to move packets from one network to another.
The directions also known as routes can be learned by a router using a routing protocol then the information is passed from router to router along the route of the destination.

IP Address's

Every machine connected to the internet is assigned an IP address. An example of an IP address would be 192.168.0.1. IP addresses are displayed in decimal format to make it easier for humans to understand but computers communicate in binary form. The four numbers that separate an IP address are called Octets. Each position consists of eight bits. When added to together you get 32 ​​bit address. The purpose of each octet in an IP address is to create classes of IP addresses that can be assigned within a network. There are three main classes that we deal with Class A, B and C. The octets of an IP address are split into two parts Network and Host. In a class A address the first octet is the network portion, this determinates which network the computer belongs to, the last octets of the address are the hosts that belong to the network.

Sub netting

Sub netting allows you to create multiple networks within a class A, B or C address. The subnet address is the address used by your LAN. In a Class C network address you would have a subnet mask of 255.255.255.0. A subnet mask identifies which portion is network and which is host. For example 192.168.6.15 the first octet three octets are the Network address and the last octet being the host (Workstation). It is important to subnet a network because gateways need to forward packets to other LANS. By giving each NIC on the gateway an IP address and a Subnet mask it allows the gateways to route packets from LAN to LAN. Once the packet arrives at its destination, the gateway then uses the bits of the subnet portion of the IP address to decide which LAN to send the packets.

Circuit Switched Leased Lines

A circuit switched network is one that establishes a dedicated circuit (or channel) between nodes and terminals before the users may communicate. Here are some terminologies associated with a Circuit switched network.

Frame relay is a telecommunication service designed for cost-efficient data transmission between local area networks (LANs)

Basic rate interference is a service used by small business for internet connectivity. An ISDN BRI provides two 64 Kbps digital channels to the user.
Primary rate interface (PRI) is a telecommunications standard for carrying voice and data transmissions between two locations
All data and voice channels are ISDN and operate at 64kbit / s

Packet Switching

Http://www.raduniversity.com/networks/2004/PacketSwitching/main.htm – _Toc80455261

Packet switching refers to protocols in which messages are broken up into small packets before they are sent. Each packet is then transmitted over the Internet. At the destination the packages are reassembled into the original message. Packet switching main difference from Circuit Switching is that that the communication lines are not dedicated to passing messages from the source to the destination. In Packet Switching, different messages can use the same network resources within the same time period.

Http://en.wikipedia.org/wiki/Asynchronous_Transfer_Mode

Asynchronous Transfer Mode (ATM) is a cell relay, packet switching network and protocolwhich encodes data into small fixed-sized cells.

ISDN is used to carry voice, data, video and images across a telephone network. ISDN stands for integrated services Digital Network. Isdn also provides users with a 128kbps bandwidth. This is done through frame relay. Frame relay complements and provides a service between ISDN, which offers bandwidth at 128 Kbps and Asynchronous Transfer Mode which operates in somewhat similar fashion to frame relay but at speeds from 155.520 Mbps or 622.080 Mbps. Frame relay is based on the older X.25 packet switching technology and is used to transmit analogue signals such as telephone conversations.

PSDN stands for packet switched data network and is a data communication network. Packet switched networks do not establish a physical communication signal like the public telephone circuit (circuit switched network) Packets are sent on a fixed length basis and assigned with a source and a destination address. The packages then explicitly on the routers to read the address and route the packets through the network.

Mobile and Broadband Services

Digital Subscriber Line (DSL) is mainly used to bring high bandwidth connections to homes and small business's over a copper wire telephone line. This is can only be achieved if you stay within the range of the telephone exchange. DSL offers download rates of up to 6mbps allowing continuous transmission of video, audio and 3D effects. DSL is set to replace ISDN and compete with the cable modem in providing multimedia to homes. DSL works by connecting your telephone line to the telephone office over copper wires that are twisted together.

Asymmetric Digital Subscribers Line is most commonly used for home users. It provides a high download speed but a lower upload speed. Using ADSL, up to 6.1 megabits per second of data can be sent downstream and up to 640 Kbps upstream.

Http://en.wikipedia.org/wiki/Symmetric_Digital_Subscriber_Line

Symmetric Digital Subscriber Line is a digital subcriber line which runs over one pair of copper wires. The main difference between ADSL and SDSL is the difference in upload and download speeds. SDSL allows the same upstream data rate and downstream data rate as ADSL upstream can be very slow.

[Http://searchnetworking.techtarget.com/sDefinition/0],,sid7_gci558545,00.html

HDSL High bit-rate Digital Subscriber Line, one of the earliest forms of DSL, is used for wideband digital transmission within a corporate site and between the telephone company and a customer. The main characteristic of HDSL is that that provides equal bandwidth in both directions.

IDSL is a system in which data is transmitted at 128 Kbps on a regular copper telephone line from a user to a destination using digital transmission.

The Local Loop enables operators to connect directly to the consumer via copper local loops and then add their own equipment to offer broadband and other services. This process involves operators accessing local exchange buildings to connect to a network of copper lines which connect them to homes and businesses. BT is an Example of a Local Exchange. The local loop connecting the telephone exchange to most subscribers is capable of carrying frequencies well beyond the 3.4 kHz upper limit.

Benefits of using DSL

DSL can provide a virtual instantaneous transmission of voice, data and video over ordinary copper phone lines. A DSL connection can eliminate delays while waiting to download information and graphics from the Internet. It provides users with a cost effective high speed Internet connection. Another benefit is that a DSL connection is always on-line (like a LAN connection) with no waiting time for dialing or connecting.

There are now more than 10 million broadband connections in the UK. By December 2005 there were 9.792 million broadband connections in the UK and the average broadband take up rate during the three months to December was more than 70,000 per week.

What is the Purpose of ERP Software?

Enterprise Resource Planning (ERP) software can be described as a complete business software solution. It is aimed at the integration of all business processes and sub-processes into a single unified system. This system is formulated and implemented in an organization to effectively and efficiently achieve the business goals of the organization.

ERP packages are implemented to manage the existing and prospective business plans and policies in an efficient manner under strict deadlines. It can be referred to as the ultimate business solution package that is predominantly concerned with making sure that the available resources of the organization are utilized in the best possible manner and coordinated with the business objectives of the organization.

It is crucial that modern day business organizations have a single unified system, which aims at harmonizing its business efforts. This can prove to be a crucial determinant in deciding the scope, area and net results of the organization as a whole, rather than running many different systems that don’t work well together. What makes ERP different from any other business solution package is the presence of a single and unified database system.

ERP software is as essential to the needs of a business today as food is for living. Businesses cannot run competitively in the absence of properly drafted and formulated ERP software. The more effective implementation and follow-up, the better are the results. ERP software is needed by all modern-day organizations, irrespective of the size, area of operations and business objectives.

Nowadays there are many ERP packages available in the global market, including SAP, PeopleSoft, Oracle, J D Edwards, and BAAN.

The selection of an ERP software package is dependent on many factors: previous software implementation, nature and size of operations, recommendations of consultants, and management decisions.

Before installing specialized software, a detailed study must be made and reviewed to match the business requirements with the available packages. This must be taken as a serious study as any mistake in selection or its effective implementation can prove disastrous to the organizational objectives and prospects.
