Answer:
The port that should be set open to allow users to access this new server is:
TCP port.
Explanation:
Ports are openings or entrance doors through which data packages have access to a PC or server. TCP and UDP are transport protocols with port numbers. TCP means Transmission Control Protocol. They are used to connect two devices over the internet and other networks. UDP means User Datagram Protocol. They are used to connect applications and to speed the transfer of data. Comparatively, UDP is faster, simpler, and more efficient than TCP. TCP enables retransmission of lost data packets, which UDP cannot do.
Answer:
<u>D. In DMA, interrupt is sent when the task is completed</u>
Explanation:
Note, the term Direct Memory Access simply refers to a computer feature that allows hardware subsystems to directly access the main system memory of a computer, without any the aid of the central processing unit (CPU).
It is a fact that while the transfer process is ongoing, an interrupt (interrupt signal) is not sent until when the task is completed.
Answer: B) Install an addition memory card to the current drive
Explanation: Drive storage space is space that has particular capacity to store files and data. If the storage reaches the capacity,it turns out that more space is required for the data storage. The hard drive is a major storage space in a system with large capacity. So, if it gets full, there are various ways it could be increased such as replacing it with other internal hard drive, external hard drive etc.
But installation of the memory card is not the solution for increasing the space because they don't have very large space and can only support small devices.
Answer:
ethics

It is also the ethical ideas and standards that society accepts as right or good as opposed to immoral or undesirable.
The SOA is the specific record type found in every zone and contains information that identifies the sever primarily responsible for the zone as well as some operational properties for the zone.
Explanation:
The Start of Authority Records (SOA) has the following information they are
Serial Number: This number is used to find when zonal information should be replicated.
Responsible person: The Email address of a person is responsible for managing the zone.
Refresh Interval: It specifies how often a secondary DNS server tries to renew its zone information.
Retry Interval: It specifies the amount of time a secondary server waits before retrying the zone information has failed.
Expires After: IT specifies the amount of time before a secondary server considers its zone data if it can't contact with the primary server.
Minimum TTL: It specifies the default TTL value for a zone data when a TTL is not supplied.
