What is cloud computing?

Many might ask, what is cloud computing? It is actually a general term for any application that distributes hosted services all around the internet with services such as Infrastructure-as-a-Service, Platform-as-a-Service and Software-as-a-Service. To further illustrate what is cloud computing, three significant features had to be pinpointed. Firstly, it is highly in demand, thus selling every […]

Comparing IEEE 802.16e and IEEE 802.20

At first, the IEEE 802.16e and IEEE 802.20 standards may appear to be very similar. Both standards were developed to specify an air interface for providing broadband access to mobile users. Both standards will have low latency and will utilize packet architecture. However, other than the resemblances of their aims, there are few other parallels. […]

Building a security roadmap

Introduction to building a security roadmap Securing a system against attack is an important responsibility of a system administrator. As a system administrator, you can address this security issue by creating a roadmap that outlines your plans for the system’s security requirements. This roadmap details what information is required to allow you to attain your […]

FIFO and WFQ

Overview of FIFO and WFQ First-in-first-out (FIFO) and weighted fair queuing (WFQ) are the two primary default queuing mechanisms that are implemented on Cisco routers. Despite a number of drawbacks, FIFO is the most-used queuing mechanism and it is supported in all versions of Cisco IOS. WFQ, which dynamically divides available bandwidth by a calculation […]

Asynchronous Transfer Mode (ATM) standards

Do you aware how many ATM standards bodies? Four main standards bodies are associated with ATM standards. The international bodies are the Asynchronous Transfer Mode (ATM) Forum and the United Nations agency, the International Telecommunications Union, Telecommunications Standardization Sector (ITU-T). The regional bodies are the American National Standards Institute (ANSI) and the European Telecommunications Standards […]

History of wireless networks

Wireless networks are communication that is done without the use of cables. Its use dates back several centuries. In the 1820’s, Hans Christian Oersted and Andre-Marie Ampere discovered electromagnetism, which is a manifestation of both the electric and magnetic fields. Then, in 1832, Joseph Henry and Samuel F.B. Morse had demonstrated how electrical telegraphy works, […]

Electronic payment methods

Smart cards A smart card is similar to a magnetic stripe card but contains a microprocessor chip. The first smart cards were prepaid telephone cards, which operated on stored prepaid values. They have moved on from this to be used for things such as library cards, credit cards, student cards, and electronic purses. Today, there […]

Security considerations on Mobile IP networks

Because of this, more efficient services and applications are available to mobile users. In business, key employees can be kept up to date with critical information, which results in […]

Enhancing Mobile IP

Mobile IP is a standard communications protocol, developed by the Internet Engineering Task Force (IETF) and designed to allow mobile-device users to move from one network to another while maintaining their permanent IP address. Mobile IP is an enhancement of the Internet Protocol (IP). It allows for Internet traffic to be forwarded to mobile devices, […]

Bandwidth on Internet Connectivity

After getting know the router on internet connectivity, there are another┬áCommunication technologies that we need to understand was bandwidth. In analog systems, bandwidth is the difference between the highest-frequency and the lowest-frequency signal components of a transmission channel. Frequency is measured as the number of cycles per second, or Hertz (Hz). In digital systems, bandwidth […]

Computer Networks

One of the primary purposes of a network is to increase productivity by linking computers and computer networks, so that people have easy access to information regardless of differences in time, place, or type of computer system. Components of a network Because companies have adopted networks as part of their business strategy, they typically subdivide […]
