Information Technology - Assignment Example

They are only sent by the agent to the manager entity. It is also in the unconfirmed class whereby operations are not acknowledged (Mauro, 2005). 3. It does not have a presentation layer (Goshima, 2011). Machine architecture simply means modes by which data and information is stored and represented in computers, circuits and the CPU. Bits, which are binary digit, are the basic unit for storage and presentation of information in the machine. They operate in two ways, either false or true, which are in the form of 0s or 1s.

Characters and integers representation in computers are all represented by a sequence of binary digits. The presentation layer is used to compress, translate, and encrypt data to the required form, so it is responsible for data displaying and managing how data is presented to the application level from the lower levels. In the internet, data sources through the application layer, are represented by unique numeric number called internet protocol addresses. Each machine or computer connected to the internet, is assigned its own IP address to use in a computer network, therefore, forming a sharing ability of available resources and information.

When one of the computers needs to access some information, the user will enter the documents name, but the machine will automatically convert it into an address that will enable the machine to identify the document. This way of representing data creates web pages, location of files and authentic sources, sending of emails and proxy availability (lammle, 2011). 4.
