Why does IPv6 use separate extension headers instead of fields in a single fixed header?
IPv6 includes an improved option mechanism over IPv4. IPv6 options are placed
in separate extension headers that are located between the IPv6 header and the
transport-layer header in a packet. Most IPv6 extension headers are not examined or processed by any router along a packet's delivery path until it arrives at its final
destination. This facilitates a major improvement in router performance for packets
containing options

Why is having a first and last name field in Microsoft Access better?
It is always better to have them as separate fields. It is very common to sort on last names and if there was a field which held the first name and last name in one field instead of two separate fields, it would not be possible to do that. If you take a phone book, the entries are always sorted by the last name. So in a properly designed database the first name and last name should always be separate fields.
Contrast the IPv4 and the IPv6 header fields?
Simplified header format. IPv6 has a fixed length header, which does not include most of the options an IPv4 header can include. Even though the IPv6 header contains two 128 bit addresses (source and destination IP address) the whole header has a fixed length of 40 bytes only. This allows for faster processing. Options are dealt with in extension headers, which are only inserted after the IPv6 header if needed. So for instance if a packet needs to be fragmented, the fragmentation header is inserted after the IPv6 header. The basic set of extension headers is defined in RFC 2460.
Udp header contains how many headers?
The UDP (User Datagram Protocol) header contains a total of four fields, which are: source port, destination port, length, and checksum. Each of these fields is 2 bytes long, making the total UDP header size 8 bytes. Unlike some protocols, UDP does not include additional headers like options or flags, keeping it simple and lightweight for fast transmission.
What are paddy fields?
Rice fields, here in Asia we sometimes use Paddy instead of rice when talking about growing the crop
What did farmers do in the season of Akhet?
Since the fields were filled with water the farmers word for the king. Instead of working in the fields they helped work on the temples and pyramids.
What does temoral extension mean?
Temporal extension refers to the duration or time span over which an event or phenomenon occurs. In various fields, such as philosophy, physics, and temporal logic, it explores how entities exist or change over time. Understanding temporal extension helps in analyzing processes, relationships, and the effects of time on different systems or concepts.
What does temporal extension mean?
Temporal extension refers to the duration or length of time that a particular event, process, or experience takes place. It involves understanding the time frame in which something occurs and the overall timeline of that occurrence. Temporal extension is important in various fields such as psychology, philosophy, and physics for studying the impact of time on different phenomena.
How did Odysseus try to get out of fighting in the war?
He pretended to be mad and sowed his fields with salt instead of seeds
Under what conditions can electric and magnetic fields be treated independently, and how does the variation in time play a crucial role in this independence?
Electric and magnetic fields can be treated independently when the sources of the fields are stationary or when the fields are in a vacuum. Time variation is crucial because when the fields change over time, they can interact and influence each other, making it difficult to separate their effects.
What is surface extension?
Surface extension refers to the practice of expanding the surface area of a material or object, often to enhance its functionality or aesthetic appeal. This can involve techniques like coating, laminating, or adding layers to improve properties such as durability, texture, or appearance. In various fields, such as materials science or architecture, surface extension can play a crucial role in performance and design considerations.

It uses a touch screen instead of physical buttons using electromagnetic fields.
