Vmware (virtual servers) - Assignment Example Question 25: The best disaster recovery for VMware is by making use of back-up process on the servers and replication of virtual machines in the network. This can be best deployed using storage where NAS is deployed for VMs and Servers in the network (Muller 123). Question 26: vMotion works by encapsulating VMs on shared storage and then the enclustered VMs allow multiple installations on an ESX server. The memory and execution state of the VMs is transferred to high speed network. This is done by copying memory and system states of the ESX server. To allow identity of the VMs, networks used by the VMs are also virtualized by the ESX server (Wolf 84). This transfer (vMotion) takes very few seconds. Question 27: A snapshot presents a complete copy of a virtual machine at any time and all the changes made. While a clone is the exact copy of the virtual machine during the cloning process. Any changes made on the parent of the clone are not reflected in the clone. Therefore using snapshots provide better functionality than clones. Question 28: Fault Tolerance in VMware works through the use of a technique known as Record/Reply. This technique provides continuous availability to the virtual machine in case the host fails.

Television Habits Essay Example | Topics and Well Written Essays - 750 words

Television Habits - Essay Example There are some advantages to allowing children to view television programming. Educational programming like Barney, Sesame Street, and Dora the Explorer are designed to promote growth and learning. Educational programming teaches valuable skills like spelling, reading, and math. Some programming teaches values, life lessons, and proper dietary habits. Commercials are beginning to educate children about the negative effects of drugs, alcohol and smoking encouraging families to spend time together. When viewed properly, television can be a strong educational tool and a means for families to spend some quality time with each other. Television viewing should lead to discussions to reinforce learning and to answer questions about the content of the program which was confusing or unclear. Although there are some advantages to allowing children to watch television, there are many more advantages to limiting television. Limiting television can create more time for family gathering and activities. Interaction with family provides opportunity for children to imitate and learn values and skills from parents. Children who are encouraged to play instead of watching television benefit from exercise and social interaction with adults and children and this helps develop appropriate social skills and healthy children. Television is not interactive and can only teach through devices like repetition and music, which does not reinforce learning. Teaching a child without the use of television or as a secondary educational source can provide reinforced learning. Hands-on activities and social interaction on topics related to the television learning will ensure that the children have learned necessary skills. Many television programs teach violence and sex while smoking, alcohol, or drugs are often depicted as fun party activities or cool to do with friends. Watching television for lengthy periods often leads to an inactive lifestyle creating obesity among children. Children become less responsive to surroundings when set in front of the television and attention spans become shorter. Watching educational programs can promote learning and if parents watch with children learning can be reinforced and questions can be answered. Viewing appropriate programming with children offers time for family and a better understanding of television content; however, lengthy viewing times are harmful for both parents and children. Television viewing can lead to long periods of inactivity and the lack of exercise can lead to obesity. Childhood obesity can lead to a negative impact on necessary social skills. "The most widespread consequences of childhood obesity are psychosocial. Obese children become targ ets of early and systematic discrimination and as they mature, the effects of discrimination become more culture-bound and insidious (Dietz, 1998, 518)." Childhood obesity can also lead to adulthood disease like diabetes, heart disease, and high blood pressure.

Quality family time away from the television should be reason enough to turn off the television. Healthy children who eat right and exercise will create a healthier and happier society. Children
