Define the two principle integrity rules for the relational modelDisscuss why it is desirable to enforce these rules also explain how DBMS enforces these integrity rules?

Mary Kenneth Keller, B.V.M. (1913 - 1985) was an American Roman Catholic religious sister, educator, and pioneer in computer science. She was the first woman to earn a Ph.D. in computer science in the United States.

1. hardware stack - a stack implemented in and entirely managed by hardware, this stack will have dedicated memory and registers in the physical hardware of the system.
2. software stack - a stack implemented with and entirely managed by software, this stack will use a small piece of main RAM and variables declared in the program software (making it much easier to modify if necessary than a hardware stack).

After completing 12th grade in computer science in India, consider pursuing a Bachelor's degree in Computer Science or related fields. Additionally, explore diploma/certification courses for specialized skills, seek internships for practical experience, and network to expand opportunities.

JNDI stands for Java Naming and Directory Interface

JNDI is an API specified in Java technology that provides naming and directory functionality to applications written in the Java programming language

Computer Science and Engineering.

Depends on the county. Some have bachelors at Mathematics Applied to Electronics and such a bachelor is in the Computer Science category. So the answer is no, those are not the only bachelors of computer science.

as a group,what are the basic visual symbols in the language of art called

A relation R is in 3NF if and only if every dependency A->B satisfied by R meets at least ONE of the following criteria: 1. A->B is trivial (i.e. B is a subset of A) 2. A is a superkey 3. B is a subset of a candidate key BCNF doesn't permit the third of these options. Therefore BCNF is said to be stronger than 3NF because 3NF permits some dependencies which BCNF does not.

The data found in the cache is called cache data. It typically consists of recently accessed or frequently used instructions or data that are stored in a smaller and faster memory area for quicker access by the processor.

Megabytes and Gigabytes.

1024 Megabytes = 1 Gigabyte.

The computer has L2 Cache on the CPU. this is very fast memory that cannot be changed.

The other type of RAM (Random Access Memory) is Main Memory, which is in "sticks" on the motherboard, usually 2-3 inches from the CPU. this memory is supplied in (DDR2):

256mb; 512mb; 1gb; 2gb; 4gb.

B.Sc(computer science) is a simple and easy to do computer science degree. it is a 3 year graduation degree with basic science, broad and theoretical science. You don't need to have excellence in maths n science for this. To get good job opportunities, student must do m.sc(cs) after b.sc. If you are comfortable with basic science and not more declined towards technical aspects of science, then B.sc is a good option.

B.tech is a tough and demanding computer science degree. its a 4 year degree with technical experience(6 months of practical internship during the graduation). Student must have expertise in maths and science,good career prospects with the choice of engineering discipline + further specialization under it gives an edge to choose and follow your career goals in that segment.

You'd need at least the DS Opera browser cartridge, which comes with a RAM expansion to go in Slot-2. The DS really isn't powerful enough for proper browsing otherwise, which is why no inbuilt browser is provided.

Five uses of a computer:

1. You can look up many kinds of information

2. You can view movies and pictures

3. You can save and edit all your photos

4. You can order things through the internet

5. You can send emails

There isn't any there is 1024kb in a 1mb and 1024mb in 1gb so the is 1024000kb in 1gb

Deadlock:

Two processes are said to be in deadlock situation if

process A holding onto resources required for process B and

where as B holding onto the resources required for process

A.

Starvation:

This is mostly happens in time sharing systems in which the

process which requires less time slot is waiting for the

large process to finish and to release the resources, but

the large process holding the resources for long time

(almost for forever) and the process that requires small

time slot goes on waiting. Such situation is starvation for

small process

• Arithmetic and logic unit (ALU)
• Control unit
• Memory
• Input output devices (collectively termed I/O)

Advantages: 1.Provides fastest services e.g collects,store,calculates,evaluate,reproduce and analyse data,run machines and instruments,informations and communications links etc. 2.Saves time and energy, 3.Provides accuracy, 4.Provides growth of informations and human developmet. 5.Remove shortage of workforce in developed societies. Disadvantages: 1.Adverse effects on human body,particulary damages eye sight and memory. 2.Since computer can do the work which many individual had to do in the past,therefore,it created un-employment in underdeveloped societies.

Input devices sends data to the central processing unit. Central processing unit (CPU) excutes computer instructions. Memory holds data and programs currently in use. In the same time secondary storage devices stores data and programs. Lastly output devices make processed data (information) available.

Keyboards, mice, printers, and monitors are four examples
