Computer Memory

passive imagination

All else being equal, it can address 2^36 words of memory, or 68,719,476,736 words (64 gigawords). If it's a "modern" computer, it probably has 8-bit words, so that's 64 gigabytes. If the word size is also 36 bits (as was common in computers in the '50s and '60s), it can address 2,473,901,162,496 bits, or 309,237,645,312 eight-bit bytes (288 gigabytes).

1 bit constitute one binary digit while 1 bytes consists of 8 bytes. 1000 bytes make one kilobyte, 1000 kilobytes make one megabyte, 1000 megabytes make one gigabyte and 1000 gigabytes make one terabyte.

Bytes. (B = bytes. b = bits.)

the CMOS 4017 is a decade counter and when you send a pulse to the input it will make the outputs count e.g. LEDS

2^20 or 1048576 kilobytes are in a gigabyte

In computers, generally the base 2 numeral system is utilized. 2^10 ~= 1000, and so each power of ten changes the prefix name in the same manner as a factor of 1000 would in other fields of study. kilo -> giga is 1000*1000 which in computer science would be represented by 2^20.

That is a matter of opinion and nothing more. Some people swear by Dodge, and others swear by Chevrolet or Ford. It also depends on what you mean by, "best". Best in hauling, towing, mpg, price, ride, handling, dependability, resale value, comfort, etc? It also depends on how the truck is equipped and with what engine. Many variables have to be considered. Each manufacture has positives and negatives. I suggest you do some research on the subject. Dependability should be one of the most important considerations. A vehicle that is unreliable is a vehicle you do not want to buy.

One, two, three...

Yes the cache memory is a static memory because if the static memory if we want to clear the memory the memory was clear because of this property it is static memory.

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

Yes you can. I move pics and other things to my tablet and computer.

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 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.

Great

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

Yes, male sheep are called rams as well as bucks.

== == Thare are 1,024 megabytes in a gigabyte, so 10,240 megabytes makes 10 gigabytes.

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...

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

eight bytes in most popular system

You need four bits for each hex digit since 4 bits can support a value from 0-15.
