On-Site Repair Service

• A computer repair technician is a person who repairs and maintains computers and servers. The technician's responsibilities may extend to include building or configuring new hardware, installing and updating software packages, and creating and maintaining computer networks. Computer repair technicians work in a variety of settings, encompassing both the public and private sectors. Because of the relatively brief existence of the profession, institutions offer certificate and degree programs designed to prepare new technicians, but computer repairs are frequently performed by experienced and certified technicians who have little formal training in the field.

Customer Service

• The importance of customer service may vary by product or service, industry and customer. The perception of success of such interactions will be dependent on employees "who can adjust themselves to the personality of the guest, according to Micah Solomon. From the point of view of an overall sales process engineering effort, customer service plays an important role in an organization's ability to generate income and revenue.

Warranty

• Although warranties are used in many contractual circumstances, they are a common feature in consumer law for automobiles or real estate purchases. For example, new car sales typically include a factory warranty which guarantees against the malfunction of the car for a certain time period. In real estate transactions, a general warranty deed may promise good title to a parcel of land while a limited warranty provides a limited guarantee of good title.

Fast and Reliable Delivery• In computer networking, a reliable protocol is one that provides

reliability properties with respect to the delivery of data to the intended recipient(s), as opposed to an unreliable protocol, which does not provide notifications to the sender as to the delivery of transmitted data.

• A reliable multicast protocol may ensure reliability on a per-recipient basis, as well as provide properties that relate the delivery of data to different recipients, such as e.g. total order, atomicity, or virtual synchrony.

• Reliable protocols typically incur more overhead than unreliable protocols, and as a result, are slower and less scalable. This often is not an issue for unicast protocols, but it may be a problem for multicast protocols.
