There are many specific duties that will vary widely depending on what type of activity the manager is responsible for. But in general terms, managers are usually responsible to ensure that the people assigned to them are doing their tasks correctly. The definition of “correctly” is where there is a good degree of variation from job to job, but it usually involves managing a budget for the people assigned to the manager, ensuring that the tasks of those people are completed on whatever schedule has been established, working through personnel issues like training if necessary, salary issues, bad performance, etc.
Four activities managers perform to coordinate resources are planning, organizing, leading, and controlling.
A content management system (CMS) is an information system that is a combination of databases, software, and procedures that organizes and allows access to various forms of documents and other files, including images and multimedia content.
They are based on the user’s actions, the content management system processes content, categorizes the content, indexes the content so that it later can be searched, and stores the content.
Two types of virtualization.
1) Server virtualization provides the capability to divide a physical server logically into many virtual servers.
2) Storage virtualization provides the capability to create a single logical storage device from many physical storage devices.
Grid computing is where more than one computer coordinates to solve a problem together. Often used for problems involving a lot of number crunching, which can be easily parallelisable.
Cloud computing is where an application doesn’t access resources it requires directly, rather it accesses them through something like a service. So instead of talking to a specific hard drive for storage, and a specific CPU for computation, etc. it talks to some service that provides these resources. The service then maps any requests for resources to its physical resources, in order to provide for the application. Usually the service has access to a large amount of physical resources, and can dynamically allocate them as they are needed.
As the demand for computing resources increases, companies may find that using outside computing resources is more economical than building new computing capacity internally. Cloud and grid com puting are two new technologies that provide flexible and massive online computing power.
Five types of e-commerce are Business to Business, Business to Consumer, Consumer to Business, Consumer to Consumer, and Mobile E-commerce
Business to Business
Business to business, or B2B, e-commerce consists of online transactions between companies, with no involvement of either company’s retail consumers. For example, an automobile manufacturer that requires 50,000 lug nuts orders them through the vendor’s website. Both the automobile manufacturer and the lug nut manufacturer sell their products to individual consumers through other outlets, but the automobile manufacturer’s order excludes both companies’ retail consumers. B2B e-commerce reduces errors while enhancing efficiency.
Business to Consumer
The type of e-commerce most easily recognized by most people, business to consumer (B2C) e-commerce consists of online transactions between consumers and online retailers or service providers. B2C typically operates in one of two ways. In one approach, the company operates a website where customers can buy the products or services directly from the company. The other model consists of a company maintaining a website that third-party companies use to sell products or services.
Consumer to Business
A classic example of consumer to business (C2B) e-commerce is a person taking bids from different construction companies to build a home. The Internet opens the door for a much wider variety of C2B transactions. C2B e-commerce typically means that a person needs a professional to accomplish a task. The consumer posts a job description to a forum or website dedicated to C2B transactions, and solicits bids from businesses. After selecting a bidder, the consumer typically pays the business through an electronic medium. Websites that cater to C2B transactions frequently offer or require the consumer to use the site’s secure financial services.
The location of backup data, supplies, and equipment, The personnel responsible for gathering backup resources and transporting them to the alternate computer facility, and a schedule indicating the order in which, and approximate time by which, each application should be up and running.
For a backup plan to be successful, the organization must back up all critical resources. Also, additional people, including possibly nonemployees, must be trained in the backup and recovery procedures because organization personnel could be injured in a disaster.
