What comes next after gigabyte?

1 terabyte (TB) = 1000 gigabyte (GB)

1 petabyte (PB) = 1000 terabyte

1 exabyte (EB) = 1000 petabyte

1 zettabyte (ZB) = 1000 exabyte

1 yottabyte (YB) = 1000 zettabyte

How much fps can you get with 6GB of ram and your video card is Intel HD graphics?

Depends on what game.

Intel HD graphics are integrated, not dedicated. So you can't expect high framerate in the higher end games like battlefield 3. You will be able to play BF3 on lowest setting at about 50-60 FPS for about 1-2 hours before you laptop/pc will overheat. Then your fps will droo to something like 30 -40. The ram is not a problem. Even 4 GB is enough. it's the graphics that matter. If you are looking forward to some high-end gaming with atleast a decent fps, I advice you to buy a dedicated graphics card.

Some recommendations:

-Nvidia GTX series(dedicated) (expensive but VERY good) - you can play BF3 at ultra graphics around 50 fps.

-Nvidia Geforce GT(dedicated) (much cheaper than GTX and decent performance) - you can play BF3 at high graphics around 60 fps. (AA filtering may lag)

-AMD Radeon HD dedicated (cheaper and decent) - Make sure that you don't buy the AMD A# series processor. (example A8, A6, A10, etc) these are intigrated into CPU. - with amd dedicated graphics, you can get 60 fps on BF3 med-high setting depending on your Graphics memory(1GB should be good, 2 GB even better). (AA filtering may lag very badly).

What is access time measured in?

What is access time rated in?

The time it take a mollecular biological "device" to

1. Recive, or gather

2. bloom or fill

3. sustain life

More specific data needed.

Can you use secondary memory in place of primary memory?

No, Because secondary takes more time as compared to primary. primary takes less time as compared to secondary.

What is the difference between a signal and an interrupt?

difference between signal and interrupts:

1. signals are asynchronous messages whereas interrupts are
synchronous(in software) and asynchronous(in computing).

2. signals are sent by kernal and handled by user mode program whereas
hardware and software interrupts are sent by hardware and
instructions in instruction set respectively and handled by kernal.

3. signal is a part of inter process communication (ipc) and interrupts
perform context switch to an interrupt handler.

generally signals and interrupts are alike and works on same logic or literally we can say that signal is a kind of interrupt.further synchronous interrupts are called exceptions.

reply me if u have some other differences ...... or any doubts...

What is mean by 3 level program memory lock in 89s52?

Program Memory Lock Bits

The AT89S52 has three lock bits that can be left unprogrammed

(U) or can be programmed (P) to obtain the additional

features listed in the following table.

Program Lock Bits

LB1 LB2 LB3 Protection Type

1 U U U No program lock features

2 P U U MOVC instructions executed

from external program

memory are disabled from

fetching code bytes from

internal memory, EA is

sampled and latched on reset,

and further programming of

the Flash memory is disabled

3 P P U Same as mode 2, but verify is

also disabled

4 P P P Same as mode 3, but external

execution is also disabled

If the cost is 75 and markup based on cost is 45 what is the selling price?

If you have a pair of jeans that a store bought for $75.00 and they mark it up 45%, then you multiply 75.00 x 0.45 = $33.75. So you add 75.00 to 33.75 and you sell the jeans for $108.75..

What is a memory mapped register?

A memory mapped register is a register that has its specific address stored in a known memory location.
