“Hexadecimal uses digits that more closely resemble our usual base-10 counting system and it's therefore easier to decide at a glance how big a number like e7 is as opposed to 11100111. Higher information density. With 2 hexadecimal digits, we can express any number from 0 to 255.”
In the font options there is a checkbox for strikethrough. Same dialog as word, only there is no button in the ribbon for it. You could customize that by creating a custom group if you want to.
Answer:
- When the primary SOA record serial number is higher than the secondary's
Explanation:
DNS(Domain Name System) is described as the distributed database that sometimes includes all the supporting hardware or software infrastructure. This system employs the internet to translate hostnames into IP addresses and provide other information related to domain.'
Under this system, the secondary name server would request the primary server to pass on a zone transfer 'in case the record serial number of the primary server zone is greater than the secondary.' <u>This will help in promoting forbearances against any kind of faults and also in establishing synchrony between the zone files</u>.

In a Transmission Control Protocol (TCP) header next Expected segment is provided by Acknowledgment Number
Explanation:
- TCP is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in the Internet Protocol.
- The fields in TCP Segment Header are Source Port, Destination Port, Sequence Number, Acknowledgement Number, Header Length, Flags, Window Size, TCP Checksum and Urgent Pointer.
- The Acknowledgment Number is a 32 Bit number field which indicates the next sequence number that the sending device is expecting from the other device.
- The SYN packets consume one sequence number, so actual data will begin at ISN+1. The sequence number is the byte number of the first byte of data in the TCP packet sent.
- If the acknowledgment flag is set in the flags field, the acknowledgment number field holds the sequence number of the next byte that the receiver expects.
