75 is a composite number because it is not only divisible by 1 and itself but also by 5.
Composite. All positive, whole numbers greater than five and ending in 0, 2, 4, 5, 6 or 8 are composite.

Executable files, data and program resource files are added to the system, configuration files (or registry files) are updated.

A command menu.

Vocational science is science education that prepares students for this specific line of work. It is based on manual and practical activities related to specific areas of science.

An ATM machine has a 4-wire, point to point dedicated telephone line which helps in connecting it with the host processor. These types of machines are preferred in places where the user volume is high. They are considered high end and the operating costs of this type of a machine is very high.

A constant variable is one that does not change during an experiment. If your experiment includes a dozen cupcakes and that number does not change throughout your experiment, the dozen cupcakes is a constant variable.

A computer is built to contain two kinds of memory. There is static memory, which stays in the computer after it is powered off. Then there is dynamic memory, which is memory that is only accessible while the computer is on. The hard drive is an example of static memory, while RAM is an example of dynamic memory.

The Preamble to the Constitution explains beautifully the reason that we fought to gain independence and lists what we need to do to protect that independence. We needed to form a strong union, have peace within and without our borders, take care of our citizens' needs and pass freedom down to future generations.

The vertical columns on the periodic table are groups. Groups show patterns in ionization energies, electronegativity and atomic radius.

The advantage of computer networking is people have the ability to interact with others with less restriction. The disadvantage is people are losing social skills.

Smart Boards were invented by a company called Smart Technologies based in Calgary, Alberta. The company was initially launched in 1987 to sell projectors for an American company.

An example of batch processing is the way that credit card companies process billing. The customer does not receive a bill for each separate credit card purchase but one monthly bill for all of that month's purchases. The bill is created through batch processing, where all of the data are collected and held until the bill is processed as a batch at the end of the billing cycle.

The Oracle of Delphi was established at the Temple of Apollo in the 8th Century B.C. Emperor Theodosius I received the last recorded response around 395 A.D. This means the Oracle was present for nearly 1,200 years.

A Subscriber Identity Module (SIM) card holds the personal information of the account holder. They are used mostly in cell phones that operate on the Global System for Mobile Communication (GSM) network. They store the account holders's phone number, address book, text messages, and other data.

Every platform (Windows, Linux, Mac, etc) requires its own driver programs for each hardware device. Drivers are written by the hardware manufacturer for each supported platform.

Requirement engineering is a process in which we identification of user requirement, analysis of requirement, validation user needs, documentation of requirement.

The scope or the life span. The life span is from the birth (allocation) to death (deallocation).

The life span of a global variable starts when the application is invoked. It dies when the application terminated. During the execution of the application , this global variable is available to any program unit within that application.

The life span of a local variable, well, only locally. "Local" means a component, a method (subroutine), or even within a bracket ({} or BEGIN-END) of a statement.

Outside of that block of codes, that local variable does not exist, hence cannot be accessed or referenced. Also, the same name of that local variable may be declared again in another local area without conflict, nor memory of the previous one.

For languages similar to C:

for (int i = 0; i < 100; i++)

{

// i can be referenced within { }, and within the for() control itself

}

for (int i = -1; i > -200; i--)

{

// this i is different from the i in the previous for-loop

}

Some computer language would allow you to declare a local variable with the same name as the global one (for example, there are global::X and local::X, but the code only refer as X). Most of the computer language would replace X with local::X at compile time, some would replace it with global::X) Some languages may not have the notion of local variables, everything is global, and some would not have the notion of global variable, but would provide a mean to act like one.

One that has blocks in rows, that you put data in, like you put name in the first block, address in box 2 etc etc.

I think I have no idea about it

Yes

The complexity of make a custom operating system depends on the knowledge of the developer.

If you intend to start a operating system from the scratch this could be a enourmous job and take some years to have a very simple and stable version.

However it is possible to customize the open versions of existing operating system as Linux. On the internet you could find out that are many others versions of Linux that are frequently updated.
