database1

Data Independence

Physical representation and location of data and the use of that data are separated
•The application doesn’t need to know how or where the database has stored the data, but just how to ask for it.
•Moving a database from one DBMS to another should not have a material effect on application program
•Recoding, adding fields, etc. in the database should not affect applications

Database Application

An application program (or set of related programs) that is used to perform a series of database activities:
•Create
•Read
•Update
•Delete
•On behalf of database users

Metadata

Data about data

In DBMS means all of the characteristics describing the attributes of an entity,
E.G.:
–name of attribute
–data type of attribute
–size of the attribute
–format or special characteristics

Java - Separators

There are a few characters that are used as separators in java. The mostly commonly used separator in java is the semicolon. As you have seen, it is used to terminate statements.

() called Parentheses used to contain list of parameters in method definition and invocation. Also used for defining precedence expressions in control statements, and cast type.

Braces {} used to contain the values of automatically initialized arrays. Also it is used to define a block of code, for classes, methods, and local scopes.

Brackets [], it is used to declare array types. Also it is used when dereferencing array values.

Comma , it separates consecutive identifiers in a variable declaration. Also it is used to chain statements together inside a for statement.

Period “ .” it is used to separate package names from sub packages and classes. And it is also used to separate a variable or method from a reference variable.

GO TO CHAPTER 2

Java - What are identifiers?

Identifiers are used for class names, and variable names. An identifier may be many descriptive sequence of uppercase and lowercase letters, numbers, or the underscore and dollar- sign characters. They must not begin with the number. Java is a case – sensitive.

GO TO CHAPTER 02

Java - What are reserved words?

Reserved words or keywords are words that have a precise meaning to the compiler and cannot be used for other purposes in the program. For example, when the compiler sees the word class, it understands that the word after class is the name for the class.

Learn more keywords

const ,finally, int , public, this, continue, float, interface, return, throw, abstract, Boolean, break,

default ,for ,long ,short ,throws, do, goto, native, static, transient, double, byte, case, catch, char

if, new , strictfp, try, else, implements, package, super, void ,extends, import, class, private, switch, volatile, final, instanceof, protected, synchronized ,while

The keywords const and goto are reserved but they are not in used.

GO TO CHAPTER 02

Java - What are comments ?

In Java, comments are preceded by two slashes (//) in a line, or enclosed between /* and */ in one or multiple lines. When the compiler sees //, it ignores all text after // in the same line. When it sees /*, it scans for the next */ and ignores any text between /* and */. Let’s look why comments are important in a program. The compiler is not going to compile the statement after the line comment or between comments. So it will skip the statement then the rest will be compiled by the compiler. So you can give any description in comments.

CPU

It is stand for central processing system; it is the brain of a computer. The CPU is built by gates. Mostly it refers as processor. It has a cycle to perform a full job. To properly perform its job, the processor has to complete a four steps cycle. The first step in this cycle is to fetch an instruction as of a software program's memory. After fetches the instruction, its second step is to decode the instruction.
During the execution step, the CPU completes the instruction. It accomplishes this by following the information gained during the decoding step. on one occasion the CPU has completed executing the instruction, the last step in this cycle is to write-back the results that occurred during the execution step. The CPU can write-back the results to its own internal register, or to the main memory of the computer.

when I update a CPU?

It is seemed much easy to update the CPU nevertheless you must know the CPU (processor) dose it much to the motherboard. The motherboard speed and the CPU must cooperate on passing signals. This are the main things before you consider to buy a CPU.

Back to CPU

How do I monitor CPU temperature?

Too much heat damages electronics. Monitoring the temperature of CPU and other computer components keep them running appropriately. To properly use most software of this type, you will need to ensure you have ACPI functionality enabled in your motherboard BIOS.

First Generation Monitoring Solutions:
Monitoring Temperature in System Bios
Numerous PC motherboards now contain hardware monitoring circuits those are capable to measure heat, voltages, and fan speeds. The majority of modern motherboards also allow you to configure alerts, alarms and actions to take based on specific temperature and fan settings.

Second Generation Monitoring Solutions:
The first generation of CPU (processor) temperature monitoring software packages purely gave the CPU temperature correct value. There is no alarms indication, events, or actions could be defined; it is very poor technology so the user must take of his or her system, to prevent the damages from the heat. If the user wasn't watching, the system could easily overheat and cause system damage.
The second generation sensor circuits have the ability to regulate and control environmental conditions automatically, so that second generation solutions are enough to keep the system stable when heat is an issue, and quiet when it isn't.

Third Generation Monitoring Solutions:
This is the newest technology software, it is directly interact with the mother board sensor and fan control system to control the heat according to the system environment condition. The mother board companies started to cover their customers and they like to give high performances from their mother board. So they are giving free software’s with their mother board.

Back to CPU

What is Dual Core Technology?

The Dual core technology became with the idea of skipping on other and manages to do the both process at simulations time and the two processors are working in parallel. A dual core processor has two processors; they are combined as one processor non as Dual core Processors. It is efficient and very fast data execution. The dual core processor occupies less space on the mother board and it uses the less electricity. The core processors each has cache this two cache improved the multitasking ability of the system (computer).

Back to CPU

How dual-core processors work

Dual-core processors work pretty much as you'd expect them to. At their most basic, both Intel and AMD have taken two mostly (or in the case of Intel, fully) functional processor cores and joined them together in a single processor die. Each core functions and processes data independently, and the two are co-coordinated by the operating system software.
