1. prior to java 7, you write to a file with a call to the bufferedwriter class's write() method. true or false? true false
Answers
True. The BufferedWriter class provides a write() method that can be used to write characters, strings, and arrays of characters to a file. Before Java 7, you would use the BufferedWriter class to write to a file.
In Java, the BufferedWriter class is a type of Writer that provides buffering for output streams. It stores output in an internal buffer, which is written to the underlying output stream only when the buffer is full or when the flush or close method is called. This can improve the performance of output operations by reducing the number of calls to the underlying system, which can be expensive. It is important to call the close method when you are finished using the BufferedWriter, as this will release any resources that it is using and ensure that the output is properly written to the underlying stream.

Which CPU characteristic when enabled, doubles the number
of instructions which can be processed at once?
Answers
Answer:
A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The term has been used in the computer industry at least since the early 1960s. Traditionally, the term “CPU” refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.
The form, design and implementation of CPUs have changed over the course of their history, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that fetches instructions from memory and “executes” them by directing the coordinated operations of the ALU, registers and other components.
Most modern CPUs are microprocessors, meaning they are contained on a single integrated circuit (IC) chip. An IC that contains a CPU may also contain memory, peripheral interfaces, and other components of a computer; such integrated devices are variously calledmicrocontrollers or systems on a chip (SoC). Some computers employ a multi-core processor, which is a single chip containing two or more CPUs called “cores”; in that context, single chips are sometimes referred to as “sockets”. Array processors or vector processors have multiple processors that operate in parallel, with no unit considered central.

Answers
In James Madison's notes on the Constitutional Convention from July 14, 1787, Mr. Sherman urged the equality of votes in the Senate not so much as a security for the small states, but as a safeguard for state governments that could not be preserved unless they were represented.
During the Constitutional Convention, the issue of representation was a contentious one. Some delegates were concerned that larger states would have more influence than smaller states, and that could jeopardize their representation in the proposed government. However, states with smaller populations were equally concerned they would be overwhelmed by the more populous states. This led to a debate about the structure of the legislative branch and how to ensure that all states, regardless of their population, would have an equal say.
Mr. Sherman, one of the delegates from Connecticut, advocated for the equality of the states in the Senate not only to protect the small states, but also because it was essential to maintain state governments as a whole. He believed that if the states were not equally represented in Congress, state governments could be undermined, as their interests would not be protected by the federal government. In his view, the issue of representation was not just about the interests of individual states, but also about the preservation of the federal system as a whole.
In conclusion, James Madison's notes from the Constitutional Convention on July 14, 1787, reveal the argument put forth by Mr. Sherman in favor of the equality of votes in the Senate. Sherman believed that equal representation was necessary not just to protect small states, but also to safeguard state governments and the federal system as a whole. This is just one example of the many debates that took place during the convention regarding the structure of the new government and the balance of power among the states.

" The small states did not want to be dominated by the larger ones in terms of representation in Congress. As a result, the Great Compromise was reached. The Great Compromise, also known as the Connecticut Compromise, was a compromise reached at the United States Constitutional Convention in 1787. This compromise resolved the problem of how to represent states in Congress.
It proposed a bicameral legislature consisting of two houses, the Senate and the House of Representatives. In the House of Representatives, the number of seats would be allocated based on a state's population. In contrast, each state would have two seats in the Senate, regardless of population. The compromise ensured that both large and small states had an equal voice in the federal government.

A student is planning her goals about the marks she should attain in the forthcoming
Semester 4 examinations in order to achieve a distinction (75%). Assuming that
examination of each subject is for 100 marks, her marks of the previous semesters
are given as under.
ACTIVITY/ QUESTIONS:
1.
Find out how many marks should she obtain in 4th semester to secure distinction.
Answers
To achieve a distinction (75%), the student needs to obtain at least 75% of the total possible marks in all four semesters. That means she needs to secure a minimum of 75% of 400 (i.e., the total marks of all four semesters) which is equal to 300 marks.
Since the student has already obtained "x" marks in the previous three semesters, she needs to obtain a minimum of 300 - x marks in the fourth semester to secure a distinction.
For example, if the student has obtained 200 marks out of 300 in the previous three semesters, she needs to obtain a minimum of 100 marks (300 - 200) in the fourth semester to achieve a distinction.
So, the number of marks that the student needs to obtain in the fourth semester to secure a distinction depends on the total marks she has obtained in the previous three semesters.
team_id INT NOT NULL AUTO_INCREMENT,
team_name VARCHAR(50),
team_rank INT NOT NULL DEFAULT 0
Refer to code example 5-1.) What are the values of the team_id, team_name, and team_rank columns after the following statement is executed, assuming that the Teams table has one row in it with a team_id of 1?
Answers
After executing the given statement, the values in the columns would be as follows: team_id = 2, team_name = NULL, team_rank = 0.
The statement mentioned does not provide any explicit values for the columns team_name and team_rank. Therefore, the default values will be assigned. For the team_id column, the AUTO_INCREMENT attribute is set, which means it will automatically generate a new unique value for each new row inserted.
Since the Teams table already has one row with a team_id of 1, executing the statement will insert a new row. The team_id column, being AUTO_INCREMENT, will generate the next unique value, which is 2. So, team_id will be 2 for the new row.
As for team_name, no value is provided in the statement, so it will be set to NULL by default.
Similarly, team_rank column does not have a value specified in the statement, and it has a DEFAULT constraint set to 0. Hence, the team_rank will be assigned the default value of 0.
In conclusion, after executing the statement, the values in the columns will be: team_id = 2, team_name = NULL, and team_rank = 0.
