Business Importance of Computer and Network Infrastructure

Computers can lower the costs of products or services by automating business transactions, shortening order cycle times, and providing data for better operational decision making. Since the 80s, a flood of IT innovations have led to efficiency gains in manufacturing firms alone-such as shortening the time to develop new products with computer aided design tools; optimizing a plant floor process with software that implements a human expert’s decision rules; and speedily changing a production line with computerized planning systems based on sales information.

IT has also been used by companies to differentiate their products or services from those of competitors. IT applications can provide sales personnel with information to help them better service a specific customer; just in time replenishments of supplies for business customers based on inventory levels rather than manually initiated purchasing orders; and decision support applications with embedded industry knowledge, such as best practices for first responders to treat a heart attack or stroke patient.

The introduction of a Web browser in the mid-1990s that used an Internet communications standard (TCP/IP) to link companies and individuals to the Internet has been described as a “killer application” due to its widespread global impact. Demands for high-speed Internet access have spurred investments by government and the private sector to install fiber-optic (high-bandwidth) lines. Today, many households in developed countries pay a monthly fee for cable, satellite, or a telephone utility for integrated data, voice, and perhaps television services in their homes. New investments by Western countries in high-bandwidth lines to their own rural areas as well as to emerging nations in Africa are also being announced to boost the global infrastructure.

Network infrastructures are being broader via Satellite and cellular technologies, now link remote workers to central support centers, travelers to travel services, and delivery personnel to transportation schedulers. Investments in wireless connectivity to better support mobile workers inside an organization’s walls have also recently increased. For example, doctors and nurses with computer and communications devices have increased their productivity and service quality by communicating more easily with clinicians on other hospital floors or at other worksites as well as by accessing electronic patient records and test results at the patient’s bedside.

Another growing trend has been the usage of the Internet to obtain remote “hosting” or other IT capabilities from “the cloud”. In Software As- a-Service (SaaS) models, third-party service providers deploy, manage, and remotely host software applications on a rental or lease agreement. This is an especially attractive option for small organizations, but industry pioneers also provide 24*7 access to distributed organizations and remote workers for Fortune 1000 companies. Other vendors offer computer infrastructure services (IaaS) via the Internet, such as computer server processing and data storage, which enable organizations to more effectively handle peak processing loads.

Computers and communication networks enable companies to compete in two primary ways:

• Low Cost-competing with other businesses by being a low-cost producer of a good or a service.

• Differentiation-competing with other businesses by offering products or services that customers prefer due to a superiority in characteristics such as product innovativeness or image, product quality, or customer service.

Next-Generation Internet And Network Security Tips

Internet and network security has become the need of the hour. For both individuals and businesses, it is very important to protect information and data. There are plenty of threats flying on the web and without proper security measures you can never fight against them. In this article we will give you important internet and network security tips prevention methods.

A computer network can be attacked in different ways like virus attacks, unauthorized access, cryptography attacks and many others. And to protect the network, there should be an updated antivirus program. In addition, you should also deploy the missing security patches in all the network computers. If you are facing difficulties for home network setup, consult a remote computer support provider.

When it comes to security threats, there are plenty of them. Denial of service, distributed denial of service, viruses as well as Trojan horses, spywares, malwares as well as unauthorized access to the network resources and data, etc. Let’s start the discussion with virus. You might know that a computer virus is a small program or an executable code. Whenever it is executed and replicated, it performs various unwanted and harmful functions for a computer and a network. Your hard disks and processors might also be destroyed by viruses. The only way to prevent viruses and other malicious objects is to install an antivirus program and update its virus database regularly.

To protect your computer and network, you should also install email scanning and monitoring program. This is because email is a big source of a viruses and malicious codes. In many cases, it is seen that hackers send mails comprising attachment which is actually a virus. If you unknowingly download this, malicious code will get installed on your computer. Apart from installing an email scanning and monitoring program on your computer, you should also have a tight security policy at your proxy server. It is also necessary block the unnecessary ports and web applications.

You should block unauthorized access to the network. In fact, you should share the network resources and data to the authorized persons. All the shared folder and resources in the network needs accessed only by the authorized persons.

To protect your network there must have a good network monitoring tool. It will help you to detect different suspicious things as well as monitor different activities in your network. These include network traffic, open ports, and useless shared folders, etc. In this context GFI LanGuard Network security scanner is a good scanning and monitoring tool. The tool is very useful to check for all the possible methods that today’s hackers employ.

What Keeps Computer And Network Consultants Up At Night?

Deciding to enter the world of consulting can be exhilarating. It can also keep you up at night worrying about whole multitude of thing. Some of the thing that computer consultants tell me keep them up counting sheep:

1. How can I get enough clients?

2. How should I deal with too much work?

3. Am I protected well enough by my contracts?

4. Are my rates too high?

5. Do I need (or want) a broker?

6. Should I grow my business or not?

7. How should I market my practice?

You probably noted that some of these contradicted others. The fact is that there
are as many ideas about computer consulting as there are consultants. As the person who owns and runs a technology consulting practice, You are unique. This is the good news and the bad news.

You may also have noticed that none of these reflect client issues. One of the misconceptions people have about consulting is that you spend all your time on client problems. It would be more accurate to say that you earn the right to spend time on client issues by handling these other issues well.

Each of the issues in this list represents a real challenge to your practice. If you can deal with them, you have an excellent chance of becoming self-fulfilled and well compensated. This book will show you ways to deal with each question, and to sleep a title more soundly at night.

The Future of Computing and Networks: Living on Cloud 9

What is Cloud Computing

In recent years, there has been a lot of “buzz” about so-called Cloud Computing. But what is it exactly? In this entry we will try to answer this question, peer into the future of Cloud Computing, as well as explain why it is so attractive to business owners.

You might hear the term “Horizontally Scalable” a lot from now on. If a network architecture is “Horizontally Scalable” this means that is easy to increase the capacity (performance, ram, speed, etc.) simply by adding on a new “node” (for example, a new physical server). The new node increases the power of the existing architecture in a seamless way. It is as if it has merged with the existing system. As an example, imagine that your employee base has rocketed from 50 employees to 1000 employees because you are getting so many new clients and work (a great problem to have!), instead of investing in new expensive servers and infrastructure to replace your current systems, you would simply add nodes. Instead of exponentially increasing costs, your costs increase at a far lower rate than your technological capacity. Cloud Computing embraces this principle.

Another key concept in Cloud Computing is “Software as a Service”, or (SaaS). The idea behind this concept is that software, and data are “Served” to the client (the machine and user requesting it) from your central technology infrastructure (Your Cloud), and are not explicitly installed or ran from the client machine. This provides many benefits in maintaining and upgrading your Information Technology infrastructure.

Why Businesses are Using Cloud Computing

As alluded to above, in the traditional model, often times network infrastructures are not designed to be horizontally scalable. Because of this, increasing capacity often involves replacing existing hardware, or adding new hardware that does not integrate with the existing system in a seamless way. Because of the ad-hoc nature of this approach, costs can rise exponentially as an increase in technological capacity is needed. Businesses clearly want to spend as little as possible on their network while maintaining the highest standards of performance and reliability. Cloud Computing addresses these needs head-on.

In addition to the obvious savings, there are also hidden savings. With cloud computing, the way in which your employees work does not change when new “nodes” are added. When new hardware and software are added under the traditional model, this is not always the case. Significant changes may need to be made to the daily work-flow. This obviously is a huge cost due to the time it takes to adjust to a new way of doing things, and to fix mistakes made in the process.

Summary

Cloud computing offers businesses the ability to grow without incurring exponentially increasing IT costs. The majority of computing operations will be done in the cloud in a few short years according to expert. In fact, much of it already is – the web browser, when accessing sites with rich functionality (like Facebook) can be thought of as a Cloud Computing access device in it’s own right. One day, however, most everything will be done in this fashion, on both large and small scales.

There are many benefits to Cloud Computing. However, deciding on a proper implementation requires expert guidance and help. Hopefully, you will now know what questions to ask if you choose to get a consultation.

How Does Computer and Network Virtualization Work?

Virtualization can be used for many technology areas. Some examples are, network virtualization, microprocessor virtualization, file virtualization and storage virtualization. Virtualization can be utilized in following ways,

1. Multiple logical representation of a single resource

• In this pattern, multiple logical resources will point to a single physical resource. This technique is used for Virtual Machines (VM). Software products such as VMWare, Microsoft Virtual Server and Xen are examples of VMs. The process of creating VMs is also known as Platform Virtualization. The advantage of this method is the resource will appear isolated, even though it is physically shared among other users. This will allow a reduction of physical hardware requirements.

2. Single logical representation of multiple resources

• In this pattern, multiple physical resources are represented in a single logical resource. Storage virtualization is an example of this method. In storage virtualization, data can be replicated easily. Since all the disks are managed from a single point, it will give easier management and scalability options. Even the virtual disk sizes can be increased or decreased according to organizational needs. Another common area of this pattern is server clustering. This type of aggregation, spanning or concentration of resources is also known as Resource Virtualization.

3. Single logical representation among multiple resources

• In this method, a single logical resource will be mapped to a single physical resource. The physical resource will be selected from an available pool or resources based on a predefined criteria. An example is virtual load balancers.

4. Single logical representation of a single resource

• This pattern is similar to the above. However, instead selecting a physical resource, the logical resource always maps to a given resource. This will help to preserve the original functionality of the back-end application.

5. Composite or layered virtualization

• This is a combination of two or more of the previous patterns. Processes are grouped as layers and each layer functions as an interface for upper layers. As a result, upper layers will get more complex and advanced functionality. An example for this is information virtualization, where advanced virtualization is generated via existing IT infrastructure.

Tips for Protecting Your Computer and Network System From Viruses

If you’ve ever had to deal with the aftermath of having a particularly nasty computer virus, you know that it’s a good idea to try and prevent any further infiltrations of your system. At the very best, computer viruses can be annoying and can cause you some difficult in accessing files on your computer. At the very worst, computer viruses can hack into your system and steal your identity, or cause a complete crash of your computer system.

While almost no system is completely foolproof when it comes to avoiding computer viruses, there are things that you can do on your home system or your office system to help make sure that you greatly reduce the risk of picking up a computer virus.

· The first rule of making sure that your computer remains as virus-free as possible is finding a good anti-virus software. Many types of anti-virus software update automatically and can be downloaded for free for your home system. For office computer systems, you may need to upgrade to the professional version of the software that you choose. You can easily research the different types of anti-virus software downloads online, so it’s a good idea to make sure that you find a program that is going to meet your needs. A good anti-virus software will be able to be updated to keep up with new viruses that are out there, and won’t use too much of your computer’s memory to run.

· If you don’t recognize the sender of an email, don’t open the email. Email is one of the easiest methods of transmitting computer viruses. Even if you do recognize the sender of the email, if it isn’t very specifically personalized and just shows a link, don’t open the link. Sometimes email boxes can be hacked to send out spam emails that transmit viruses or spyware to other systems. If you get a suspicious email from someone that you know, make sure that you check it out before you open the attachment, and that you let your contact know that they are inadvertently sending out emails.

· Consider adding filters in your internet browser that can help to filter out harmful sites or sites that have a bad reputation. Filters and ad blocks can also help to make sure that you don’t get constantly harassed by pop up ads or other types of ads.
