Data classification important practices

Some data classification best practices include first identifying the source of data and types of the same across the organization. This helps decide which data to retain, store or delete. It also gives an insight to the access patterns of the data. Another aspect is to establish categorization of data before making any decision that is technological. Sort records depending on their category. It is also important to identify and specify access methods as well as authentication methods to the same data (Mark, 2008).

NETWORK TERMINOLOGIES

1. Impact of network congestion on productivity
Network congestion occurs when a link or a node carries too much data that its normal capacity thus making its efficiency to be reduced. Some of the effects of network congestion include: queuing delays, blocking of new connections and packet losses in the network. (Floyd & Fall, 2009) Network congestion leads to an overall reduction in the network’s throughput. Network congestion usually affects the productivity of the network in the following Continue reading...

The future of data security and information assurance is aimed at providing quality services to the right people and at the right time. In recent times, data security and information assurance aims to improve its services to the immediate consumer in the world of business which is currently adapting the internet-centric environment. This means that the internal enterprise is operating with the external enterprise in its service provision- management of its operation and application (Whitman & Mattord, 2011, p. 98). This internet centric environment is advantageous in that it is able to cover a larger system rather than monitoring a Continue reading...

Ethernet and token ring protocols are the common wan technologies in use today. Ethernet employs Bus technology where all machines are connected on a backbone. Any data sent from any machine can be transmitted through the network with the condition that the network is free of any other traffic. If the destination of the send packet is not found it is eliminated otherwise it is received at the destined node (Stallings, 2007). Token Ring protocol though has a different approach. Computer systems are interconnected in a loop. There is a monitoring node that controls the movement of data in Continue reading...

During the practicum, I felt myself not only learning as a teacher but also as an individual too. I mean this in the sense that before I began the practicum, I was less organised and much less confident but, as a result of this course, I now feel as though I am a lot more gregarious, prepared and generally more ‘together’ than I was before. Having spoken to a number of teachers now, it seems that all teaching practicums are intense and hard work – demonstrating the challenge of the job Continue reading...

Data signal is a light of frequency or that of electricity, which represents data as they go through a network or a computer channel or through a wireless network. Data signals are the electrical signals that are used to carry information in terms of data. Data from the computer are converted to electrical signals. On the other hand, voice signals are the electrical signals that are used to transfer voice from one point to another. A typical voice signal has a bandwidth of approximately 3 kHz. A video signal is a signal that transmits pictures and graphics from one Continue reading...

The open system interconnection model (OSI) is based on the open system interconnection. The communication system is sub divided into layers with each layer providing services to the other layers (Behrouz, 2006, p. 17). This model is composed of seven layers arranged logically in order from the physical layer to the application layer.
The physical layer performs majorly electrical and mechanical aspects of the network. These includes the establishment and termination of connection to a physical medium and conveying bit streams in form of electrical impulse, light or radio signal. The physical layer protocols are the ATM, RS232 and Continue reading...

Packet switching vs. circuit switching

Packet switching is a form of transmission technology that allows the transmission of data in small separate groupings or blocks basically known as packets (Rosner, 1982). Each packet contains the destination address, therefore seeking its own path. Circuit switching on the other part employs a technology whereby a destination path (dedicated path) has to be established in order for data to be transmitted. The dedicated path remains in use for the entire period of transmission and is only released after completion of transmission (Dhotre, 2006). It differs from packet switching in that, in circuit Continue reading...

Comparing and Contrasting 3G and 4G Networks

Introduction

The evolution of cellular mobile communication networks in the last twenty years has been so quick, leading to a situation whereby the technology is evolving so quickly. In the early ages of mobile communication, data communications were in forms of dial up connection, which were totally unpredictable and slow. With time, wireless access protocol (WAP) was superseded by the general packet radio services (GPRS), which provided improved speeds and functions. With time, developers were able to develop an enhanced form of GPRS known as EDGE in 2. Continue reading...

Answer the following activity questions below:

1. In terms of collisions and speed, what are the differences between hubs and switches?

Switches transmit data at a faster speed as compared to hubs. There are no collisions when using switches whereas when using hubs you are likely encounter collisions. This is because only one data packet can pass through a hub at any particular time. Therefore when a computer tries to send a data packet to the hub while it is broadcasting, then a collision will occur. (Tanenbaum, 2003)

2. How do switches solve network congestion problems on Continue reading...

Wireless LAN has various advantages including cost advantage, convenience and productivity. However, the radio waves subject the network to various risks which can lead to hacking. The three main security issues considered before implementing a Wireless LAN are highlighted hereunder.

Denial of Service

Here, the network intruder floods messages, either valid or invalid, into the network. These messages affect the availability of the resources of the network. WLAN are highly vulnerable against this kind of attack. WLAN has relatively low bit rates which can easily get overwhelmed, exposing them to denial of service attacks. During the implementation of a Continue reading...

Static or dynamic IP routing

IP routing is described as the task of sending data packets via the router from a host to a destined remotely available host on another network (Osterloh, 2001). In order to deliver its data, routers maintain a path which is defined in the routing table.
There are two types of routing, dynamic and the static routing techniques. As the names suggest, dynamic routing protocol uses a dynamic table while the static uses static tables for path determination. Maintaining of static tables is done manually by the systems or network administrator while dynamic tables are Continue reading...

Introduction

Over the years the growth and development of the internet has brought many opportunities for businesses and individuals to gather personal information about other users and to direct their advertising at these people. However, the means by which these things are done give rise to many ethical issues. For one thing, there is the question of whether an individual’s browser history is his or her private property, or is it something which others should be allowed to share? Another issue is at what point are companies being simply unethical? At what point are they breaking Continue reading...

During classifications, entities are to use inputs for measuring fair value according to the three level hierarchies. We start from the highest then moving to the next until we get one which is available. The three levels used are:

Level 1: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2: Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs Continue reading...

Software that meets its functionality requirements coupled with tight and impenetrable security features and controls is desired software by all organizations and individuals. In as much as there has been advancement in security implementation in software, vulnerabilities have always been seen in them. Some of the security risks are associated with poor development of the software while some are due to poor policy framework and software usage. In the past, there has been software security breaches that ended up causing undesired effects Continue reading...

The practice of outsourcing has increased tremendously in the business sector due to the numerous benefits that accrue from outsourcing. Outsourcing improves efficiency and reduces operational costs. However, businesses cannot outsource all of their functions. Below are examples of functions in an airline operation that are most and least amenable to be outsourced.

Customer service is one of the functions that is most amenable to be outsourced. Instead of the airline hiring numerous individual operators, it can contract a single call centre to handle customer calls. It is inefficient for the airline to handle its own call centre Continue reading...

General Questions

According to Hamblen and Lawson (2008), the switch in question offers the ability to transfer huge amounts of data in a short time. In their analysis, the switch could provide the initial ability of transferring more than 8Tbit/sec and later 15Tbit/sec. The switch also offers the ability of partitioning allowing different users to run separate processed while utilizing the same computational and power mechanism.
Virtualization of data centers would be realized based on the switch potential to be divided logically while offering high speed connections. It would allow sharing of resources while having logical divisions that can Continue reading...

Information life-cycle management (ILM) is a concept, which emerged in response to the growing amount of information and relatively high storage costs. In the core of this activity is determining information needs of a company, and evaluating the appropriate level of expenditures on its storage. It is based on the assumption that information follows a particular life-cycle, from capturing to an eventual decline. At each stage, information has different value for the company, therefore requiring different measures to insure its safety.

One of the most common approaches to ILM is assessing cost structure, which is usually represented by the Continue reading...
