Answer:
Register-it contains all the instructions that are present in the processor.
Memory location- it is the particular memory address where the data is stored.
Explanation: Difference between register and memory location are as follows :-
- Register are the found in the CPU internal storage and memory location is present on the RAM.
- Registers are faster in movement as compared to the memory location.
- Register has the capacity of holding of less data as compared to the memory location which can store data in large amount .
Answer:
D. A DNS server asks another DNS server to resolve a domain name
Explanation:
DNS (Domain name system) queries are essentially of two types;
i. recursive address resolution
ii. iterative or non-recursive address resolution
=> In the <em>recursive address resolution</em>, which represents a recursive query, when a DNS server A, receives a request from a client and does not know how to resolve such request, the DNS server sends the query to another DNS server B on behalf of this client. DNS server B can either reply to the query with the actual answer or an error message. If it's an actual answer, it returns to the client. Otherwise, it queries another DNS server, say C.
=> In the <em>iterative address resolution</em>, once the DNS server A receives a request from the client, it tries to reply the client with the best answer it can give. If the DNS server A does not have an answer, it refers the client to another DNS server say B. In this case, the server A does not directly query the server B. Instead, it refers the client to the server B.
Answer:
the system development life cycle (SDLC) is the overall process of developing, implementing, and retiring information systems through a multistep process—initiation, analysis, design, implementation, and <u>maintenance to disposal.</u>
Explanation:
There are several SDLC models and each generally consists of a numbers of definite stages. For a given adopted SDLC model, information security and product services must be integrated in to the SDLC to ensure appropriate protection for the information that the system will transmit, process, and store.
