[Q] Radiation patterns can be used to classify antennas into what two basic categories?

The vitality transmitted by a radio wire is spoken to by the Radiation pattern of the antenna that is of two basic categories i.e. unidirectional [emits a signal in one direction] and omnidirectional [emits a signal in many directions]. Here, getting and transmitting radiation patterns for a solitary receiving wire are indistinguishable into two sorts of radiation examples ought to be recognized: [1] the free space radiation pattern that is the finished flap example of the radio wire and is an element of the frequency, feed framework, and reflector qualities; and [2] the field radiation pattern that contrasts fundamentally from the free space design by the development of obstruction projections at whatever point immediate and reflected wave trains meddle with one another, as is found in most surface-based radars.

[Q] What is hashing, and how does it differ from encryption?

Hashing is a technique for single direction encryption. This implies you won't have the option to utilize a foreordained key to translate the data when you hash information. Moreover, your yield concluded hashed information doesn't contain the data important to decode it. The essential is the hashing calculation where the cryptographers have set up many successful hashing calculations that are typically gotten from the numerical characteristics of your information as opposed to the semantic characteristics.

Hashing differs from encryption as:

[a.] Hashing is a single direction process the info is basically mixed utilizing a calculation you can rethink to recover your information. It's considered a single direction in light of the fact that, even with the correct calculation, you can't unscramble yield to reproduce input. That is the reason secret word encryption frequently utilizes hashing. An assailant can't reproduce a hashed secret word regardless of whether they access the hashing calculation whereas Encryption, then again, is a two-way process. Information encryption utilizes an assortment of systems to encode input dependent on numerical, computerized, and semantic attributes.

[b.] Though hashing calculations are irreversible and worked to give honesty so as to confirm that a specific bit of information has not been altered, encryption calculations are reversible [with the key] and worked to give privacy.

[Q] The DiffServ technique for addressing QoS issues defines what two different types of data stream forwarding?

DiffServ [Differentiated Service] is a straightforward system that addresses QoS issues by organizing traffic. To organize traffic, DiffServ places data in the DiffServ field in an IPv4 datagram. This data demonstrates to the system switches how the information stream ought to be sent. Defining two unique kinds of data stream forwarding:

[a.] Expedited Forwarding: is utilized to give assets to idleness [delay] touchy ongoing, intuitive traffic.

[b.] Assured Forwarding: is utilized to give need esteems to various information applications.

[Q] The creation of a response team should include what team roles?

Team Roles:

Roles	Responsibility
Team Leader	Facilitates and energies all occurrence response team movement, and keeps the team concentrated on limiting harm, and recouping rapidly.
Lead Investigator	Gathers and dissects all proof, decides the main driver, coordinates the other security experts and executes quick framework and administration recuperation.
Communications Lead	Leads the exertion on informing and interchanges for all crowds, outside and inside of the organization.
Documentation and Timeline Lead	Archives all team exercises, particularly examination, disclosure and recuperation assignments, and creates a dependable course of events for each phase of the occurrence.
HR/Legal Representation	Similarly, as you would figure. Since an occurrence could possibly form into criminal allegations, it's fundamental to have HR and lawful direction and interest.
