Answer:
A, Routers
Explanation:
Routers are used
The devices used in networking are:
A. Routers
D. Switches
Thus, option (A) and (D) are correct.
A. Routers: Routers are network devices that facilitate the transfer of data packets between different networks. They determine the best path for data to reach its destination and enable communication between devices on separate networks.
B. Hubs: Hubs were commonly used in early networking but are now outdated. They are passive devices that broadcast data to all connected devices, leading to inefficient data transmission.
C. TCP: TCP (Transmission Control Protocol) is not a networking device but rather a communication protocol used in the transport layer of the TCP/IP protocol suite. It ensures reliable data delivery by establishing a connection between devices and managing data flow control.
D. Switches: Switches are network devices that connect multiple devices within a local area network (LAN). They forward data packets only to the intended recipient, allowing for efficient data transmission within the same network.
Thus, Routers and Switches are parts.
Thus, option (A) and (D) are correct.

In SQL the statement select*from R,S is equivalent to:_______(a) Select * from R natural join S(b) Select * from R cross join S(c) Select * from R union join S(d) Select * from R inner join S
Answer: (b) Select * from R cross join S
Explanation: The SQL query command, Select * from R, S selects each rows from table R and merges combines it with each row of table S such that the number of columns increases. The merging could be said to be horizontal in nature since it results in an increased number of data columns. The Cross join method produces the same exact result with the output all columns in both tables (R and S). The inner join combines rows in tables as well but requires that both tables have a matching column values. The union join merges data the data in both tables vertically and will not produce the same output as the SELECT * FROM R, S statement.

How to represent derived attributes in database?
Answer:
Derived attribute can be defined as a type of attribute where its value will be derived from one or more of the other attributes of the same entity set.
Explanation:
An example of derived attribute is when we have an entity set called General. The set then has attributes like [Form], [Characteristics], [Address}, (Employment No).
(Employment No) which is represented distinctly in the attribute set can be called a derived attribute if it can be derived from one or more of the other attributes.
Derived attribute can be gotten through calculating values and not storing values.
For example, let us consider the following record of Teachers records;
(‘Teacher Number’, ‘Name’, ’Date of Birth’, Age today)
(‘E105’, ‘Samson’, ’07-Dec-1990’, 0)
This record shows that the teacher Samson was born on 7th of December, 1990. At the time of record insertion, he was born and 0 years old. What will be the value of his age on ’07-Dec-2000’? It is about 10 years. It clearly shows that the value is not fixed and it is a variable whenever the DOB is adjusted.
Therefore, we are not creating our table with derived attributes in it. Instead, the values ofderived attributes can be calculated at the time of retrieval and shown to the user. Hence, the record will look like as follows;
(‘E105’, ‘Samson’, ’07-Dec-1990’)
This means that 0 is a derived attribute from the Date of birth.

Why is it important to use systems analysis and design methodologies when building a system? Why not just build the system in whatever way seems to be "quick and easy"? What value is provided by using an "engineering" approach? Also, Give a specific example of an organization (not one listed in the book) that does a good job of this and why.
Answer:
It encourages the documentation of the building process and serves as a good reference point when information about the system is needed. It also helps in the testing of the various components of the system for efficiency.
Explanation:
System analysis is the total evaluation of the working components of a system. it shows the health or functionality of components and analyzes the effect of their relationship on the total system performance.
The design methodology is an engineering process to achieving a complete system build. It follows a procedure, documenting its parameters and observations as the system is implemented.
Example of organizations that follows these methods in building their systems are automobile industries like Honda.
It promotes the recording of the construction process and acts as a helpful resource when details about the system are required. Additionally, it aids in the efficiency testing of the system's many parts.
What is System Analysis?"The process of evaluating a procedure or business to define its aim and purposes and build systems and procedures that will efficiently achieve them," according to the definition of systems analysis.
System analysis is done to investigate a system or its components in order to pinpoint its goals. It is a technique for solving problems that makes the system better and makes sure that all of its parts function effectively to serve their intended purposes.
Six essential steps can be taken while creating a system. Systems analysis entails specifying the problem, its causes, the proposed solution, and the information need that a system solution must satisfy.
System analysis has a wide range of advantages, but it may also have significant drawbacks. The danger of conducting excessive analysis, which may be expensive and time-consuming, is one of the key drawbacks that is frequently disregarded. Finding the ideal balance is consequently a necessary aspect of the analyst's job.

You modify a document that is saved on your computer. Where are the changes stored until you save the document?a. Radom access memory RAMb. Read-only memory (ROM)c. Compact disc (CD)d. Universal serial bus (USB)
Answer:
a. Radom Access Memory (RAM).
Explanation:
If a computer user modifies a document that is saved on his or her computer. This changes are stored on the Radom Access Memory (RAM) until the computer user save the document.
Radom Access Memory (RAM) can be defined as the main memory of a computer system which allow users to store commands and data temporarily.
Generally, the Radom Access Memory (RAM) is a volatile memory and as such can only retain data temporarily.
All software applications temporarily stores and retrieves data from a Radom Access Memory (RAM) in computer, this is to ensure that informations are quickly accessible, therefore it supports read and write of files.
The changes made when a document is modified before saving is stored on; A: Random Access Memory(RAM)
Radom Access Memory (RAM) can be defined as the short term memory of a computer system which makes it to handle all tasks and applications.
Thus means that RAM is a kind of temporary storage that will go off when you shut down the computer. Thus, it is the memory that is required for saving active changes you make before saving.
