How do I find error corrections in an EAN-8 barcode?

Answer:

a. 7 bits b. 9 bits c. 1 kB d. 2¹⁶ - 1

Explanation:

a. How many bits are needed for the opcode?

Since there are 72 different operations, we require the number of bits that would contain 72 different operations. So, 2ⁿ ≥ 72

72 = 64 + 8 = 2⁶ + 8

Since n must be an integer value, the closest value of n that would contain 72 different operations is n = 7. So, 2⁷ = 128

So, we require 7 bits for the opcode.

b. How many bits are left for the address part of the instruction?

bits left = bits per word - opcode bit = 16 - 7 = 9 bits

c. What is the maximum allowable size for memory?

Since there are going to be 2⁹ bits to addresses each word and 16 bits  for each word, the maximum allowable size for memory is thus 2⁹ × 16 = 512 × 16 = 8192 bits.

We convert this to bytes

8192 bits × 1 byte/8 bits = 1024 bytes = 1 kB

d. What is the largest unsigned binary number that can be accommodated in one word of memory?

Since the number go from 0 to 2¹⁶, the largest unsigned binary number that can be accommodated in one word of memory is thus

2¹⁶ - 1

Answer:

The name should be readable and make sense

Explanation:

Aside the rules involved in naming variables, there are also some good tips which should be considwred when given names to our variables. These means there are some variables which are acceptable by our program but may be avoided in other to make our codes easier to read by us and others and it also makes debugging easier when we run into errors. Using short variables are acceptable on code writing as far as the rules are followed. However, it is more advisable to use names that are descriptive and readable such that it relates to the program or code being worked on. This ensures that we and others can follow through our lines of code at a much later time without making mistakes or forgetting what the variable stands for.

SELECT college, city_state, accre_agency, distance LIMIT 10

Explanation:

Given

Table name: College

See attachment for table

Required

Retrieve top 10 college, state, agency and school distance from the table

To retrieve from a table, we make use of the SELECT query

The select statement is then followed by the columns to be selected (separated by comma (,))

So, we have:

SELECT college, city_state, accre_agency, distance

From the question, we are to select only first 10 records.

This is achieved using the LIMIT clause

i.e. LIMIT 10 for first 10

So, the complete query is:

SELECT college, city_state, accre_agency, distance LIMIT 10

Answer:

Explanation:

If the computer is starting up and getting into windows then this means that the processor itself is not dead. First, check to see if the processor fan is spinning correctly when turning on the computer. If it is, then you will need to remove it, and make sure that the processor is perfectly slotted within the cpu slot and that no pins are bent. If this is the case, then clean the cpu top with an alcohol swab and reapply thermal paste. If it is overheating due to any of these reasons it would cause the pc to power off in order to preserve the processor. If none of these fix the problem then it might be a faulty processor or a problem with another component such as the RAM or power cables.

Answer:

A.

Explanation:

In computer science, the selection of a lockable device is an essential consideration in the creation of a database management system.

Granularity locking is a locking technique that is applied in database management systems (DBMS) as well as relational databases. The granularity of locks corresponds to how much data is locked at once, and it is determined when S lock (Shared Locks) are released.

The moment that S-locks are released will determine the granularity of locks (Option a).

In conclusion, the moment that S-locks are released will determine the granularity of locks (Option a).

Answer:

False.

Explanation:

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

In Computer programming, an array can be defined as data structure which comprises of a fixed-size collection of variables each typically holding a piece of data and belonging to the same data type such as strings or integers.

This ultimately implies that, when a programmer wishes to store a group of related data (elements) of the same type, he or she should use an array.

Generally, character positions in arrays start counting with the number 0 not 1.

Hence, an array uses a zero-based indexing and as such the numbering or position of the characters (elements) starts from number 0. Thus, the first character (element) in an array occupies position zero (0), the second number one (1), the third number two (2) and so on.

Explanation:

All of the code snippets provided are missing small details such as brackets in the correct places and '=' to signal an assignment. These are crucial when coding in Java and the code will not run without it. Regardless, the only implementation that is correct in the options would be implementation III. It is the only code snippet that is correctly structured to reverse the order of the elements. It will still need debugging in order to get it to work.

public static void reverse (LinkedList alist) while (aList.size ()>0) while (Itemp.isEmpty()) Stack temp new Stack ( temp.push (aList.removeLast ()) aList.addFirst (temp.pop ());

Answer:

9 10 6 4 7 1

Explanation:

When the values are pushed to the stack they would end up in the stack in the same order as they go in.

1 7 4 6 10 9

when elements are popped from a stack they are removed from the end to the beggining of the stack, and since these elements are being added to the priorityQueue then priQue will have the following order

9 10 6 4 7 1

this will also be the order that the numbers will be printed out from left to right since priorityQueue remove method, removes the elements from left to right.

Answer:

A setter method

Explanation:

A setter method will accomplish this. A setter method is a method that takes in a value as an argument and grabs an object's instance variable and modifies it with the value passed as an argument. In this scenario, the argument value would be the current JerseyNumber. The setter method will grab the object's jerseyNumber variable and change its value to be the value of the passed argument. Setter methods are common practice in all object classes as well as the getter methods to retrieve instance variables.

Answer:

(a) Supplier

Explanation:

In database design, two tables are linked together using a FOREIGN KEY. A foreign key is formed from one or more columns of one table that reference or match another key (often called a primary key) in another table. In other words, when a column or a combination of columns on one table points to a primary key of another table, the column(s) will specify the foreign key.

PS: A primary key is used to make each entry of a table unique.

In the given tables - Supplier, Product, Country -  since the Supplier table has a column called CountryId referencing the CountryId column of the Country table, then CountryId is a primary key in Country table but a foreign key in Supplier table.

Therefore, the CREATE TABLE statement(s) of the Supplier table must specify a foreign key.

A database management system often reads and writes data in a database, and makes sure there is consistency and availability. The supplier table's CREATE TABLE statement(s) must specify a FOREIGN KEY.

The Select SQL statement does not alter any database data. A supplier database is made up of different list of service, product or materials providers who can meet orders quickly.

Explanation:

Customers want to be provided with good service when they shop so it is important that employees are able to do so and they can only do so if they have the tools required. The company should therefore make those tools available thereby empowering employees to provide great service.

Making follow-up calls to customers after they receive a service to check if the service is working out will build customer relations because they will feel that the company cares. Finally, asking customers of their opinions on improvements needed makes them feel they have a voice and will go a long way in establishing rapport with them.

The Newton's method (Newton-Raphson method) used in advanced statistical computing can be used for a continuous and differentiable function that can be approximated by a straight line tangent to it. It requires the derivative of the function to be known, Newton's method converges faster that is whenever it converges. Newton Raphson Method has quadratic convergence which is faster, and the quadratic convergence makes the error in the next iteration increase by the square of the value of the previous iteration.
