Complete Question:
A system has defined specifications that describe how signals are sent over connections. Which layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model provides this function?
Group of answer choices.
A. Transport
B. Network
C. Data link
D. Physical
Answer:
A. Transport
Explanation:
Transmission Control Protocol/Internet Protocol (TCP/IP) model is a standard communication protocol used for interconnecting network devices such as routers, switches, host computers and access points over the internet.
A system has defined specifications that describe how signals are sent over connections. The layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model that provides these functions is the transport layer.
The transport layer comprises of two (2) standard protocols and these are TCP and UDP.
TCP is an acronym for Transmission Control Protocol and it is one of the essential and important protocol of the internet protocol network. This simply means that, it is an essential part of the TCP/IP network. The TCP has a wide range of applications in the following areas, file transfers, world wide web, remote administration, e-mail, etc.
The TCP connection are mainly established in the network using the three-way handshake.
UDP is an acronym for user datagram protocol and it enables the transfer or exchange of data between network devices.
Answer: binary
Explanation:
Conceptual design refers to the early phase of the design process, whereby the outlines of function are articulated. The conceptual design consist of the design of processes, interactions, and strategies. It is the first stage in the database design process.
The output of the conceptual design process describes the main data entities, and constraints of a particular problem domain. To simplify the conceptual design, most higher-order relationships are decomposed into appropriate equivalent binary relationships whenever possible.
Answer:
1. - Observer
2. - iterator
3. - strategy
4. - composite
5. - decorator
Explanation:
An object contains other objects (elements) and must give access to them for clients, without exposing its internal structure. This is an observation.
The subject-object can generate events as an iterable (iterator) and could use different strategic algorithms to achieve a task. Class objects can be used to aggregate other class objects.
In python, the decorator function mimics the outer function of a nested function, but still maintains the functionality of the second function
Answer:
Storage Spaces Direct feature implements software-defined storage and is intended to make storage more versatile by making it easier to add storage, access storage, and use new storage capabilities
Explanation:
Storage Spaces Direct feature appeared in Windows Server 2016 and it is a <em>distributed data storage technology. </em>
Storage Spaces Direct enables local drives of several servers into a fault-tolerant, scalable storage secured from problems of both separate disks and entire servers. Using this feature, one can create virtual volumes on local drives and use them as common clusters to store virtual machine files.
