Your computer freezes when opening document from flash memory?

This is due to the file being corrupted on the flash memory. It can also mean your flash memory is infected by a virus and it spreading it to your computer.

Who is associated with the creation of Pentium chip?

Intel Corporation created the Pentium chip. They had previously created all their microchips with numerical identification. Their main series up until that point included the 286 (technically called the 80286), 386, and 486. They were frustrated by the fact that their competitors were naming their chips the same way or very similarly. They tried to make the number-names into trademarks but discovered that one cannot trademark a number. Therefore, to keep the competition from using their naming scheme, they decided to call their next chip the 'Pentium', and they trademarked the name.

What do you mean by off-chip memory in microcontroller?

The memory that is use externally when microcontroller works in expanded mode for special cases .

What kind of antifreeze does a 2003 Chrysler Sebring take and what should be done if the gauge keeps going up to hot and then back down and then back up?

It probably needs a thermostat. The Chrysler 2.7 litre engine is bad about getting air into the cooling system and needs to have the air bled out. The temperature sensor is located at the top of the engine, just left of the intake manifold as you stand in front of the car. Also, right next to the air bleed manifold. Be careful, the bleed manifold is mostly plastic and is easy to break. With the car running, attach a preferably clear plastic hose to the top of the air bleed manifold fitting and put the other end into an empty jar or bottle. Now, open the bleed fitting by turning clockwise and watch the antifreeze water mixture air bubbles in the hose until the flow is clear of all air bubbles. It may be necessary to complete this task two or more times. As stated above, the temperature sensor is at the top of the engine and when it is low on water, there is no water reaching the sensor, so when you speed up the engine rpm, the water is pumped up into the top of the engine reaching the sensor and causing the water temperature sensor to show the temperature increase. Low water level shows low temperature readings.

How many nibbles in a megabyte?

Incorrect

There are exactly 2 million nibbles in a megabyte (MB).

Correct:

4 Bits = 1 Nibble

8 Bits = 1 Byte

1024 Bytes = 1 KiloByte

1024 KiloBytes = 1 MegaByte

1024 MegaBytes = 1 GigaByte

1024 GigaBytes = 1 TeraByte

2 x 1024 x 1024 = 2,097,152

There are 2,097,152 Nibbles in a MegaByte

mega- is the SI prefix for "1 million", so 1 MB = 1,000,000 bytes.

1 byte = 2 nibbles, so 1 MB = 2,000,000 nibbles.

There are 2,097,152 nibbles in a mebibyte (MiB).

4 bits = 1 nibble (or nybble)

2 nibbles = 1 byte

1024 bytes = 1 kibibyte (KiB)

1024 kibibytes = 1 mebibyte

1024 x 1024 = bytes in a mebibyte

Here is the math:

bytes in a mebibyte x 2 = nibbles in mebibyte

2 x 1024 x 1024 = 2,097,152

You have dual channel 512mb RAM right now can you put another 2gb dual in and have two dual channel set ups running at the same time?

By dual channel 512, do you mean you have 512x2, or you mean 206x2. anyway, unless you're making your own computer, and not running a laptop it is nearly impossible to have even 2gb, because that would mean 1x2 which is already alot of money and everything. they dont make 2gb cards all by themselves, you have to run two cards.

Are all DDR SDRAMs interchangeable?

Yes, but only with other DDR, not SDR. DDR is 184 pins where SDRAM is 164 pins. There are a few factors that will affect the speed of you memory: 1) The memory itself If you buy cheap memory then you might have slow memory. the chip can only move as fast as its slowest memory section 2) Maximum clock speed on the motherboard Your memory will only run as fast as your mobo can run it. If your mobo supports up to PC2700, buying PC3200 will only run at PC2700 speeds

How do you reset the computer on a 1999 Dodge Ram?

disconnect the negative battery cable for about a minute, this should reset the check engine light

What does Cache Memory Failure means and how can you fix the problem that has caused it?

This sounds like a problem with a piece of hardware (a cache memory chip), either on your motherboard, or on your hard drive's controller (a read-ahead buffering chip). Being hardware, you cannot ''fix it'', only replace the faulty chip. You can replace the cache memory chip if it's on your motherboard, though you'll have to: locate it, remove it, identify it, find a source, order a replacement chip, and reinstall the new chip without damaging it. Look for a shareware memory-testing utility, and run it on your computer. To test your hard drive, you might be able to download a trial version of SpinRite (http://www.grc.com/sr/spinrite.htm), put it on a bootable floppy, and see what kind of errors it finds on your hard drive's electronics. If the problem's in the hard drive's controller's cache chip, you could attempt to back-up the drive, then send it back to the manufacturer for repair. Hopefully the warranty is still good. If you are not computer hardware-handy. you should take your computer into a computer repair shop and have them diagnose and fix it.

Magnetic tape can also be known as magnetic what?

Magnetic tape is also known as magnetic media. Magnetic media is used for recording and storing video, audio, and digital signals.

What is used to connect the CPU directly to RAM?

The central processing unit (CPU) of a computer is interfaced to the random access memory (RAM) via the front side bus (FSB). Additionally the Northbridge is/can also be interfaced with the CPU through FSBs.

Differentiate between the physical virtual and cache memory Explain briefly?

Virtual memory is a type of memory that is allocated by the operating system and is used to speed up operations. Cache memory is RAM that the CPU can access faster than regular ram which is considered physical memory. When the CPU is looking for data, it checks the cache memory first, recently used data will still be in the cache. If it does not find it there, it moves on to use the physical memory. Anytime a program or file is opened, it is first loaded into RAM (physical memory).

What is the function of SIMM?

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.

What is magnetic disk?

RAM:(RANDOM ACCESS MEMORY)

RAM is the primary storage device and the data and instructions are stored temporarily in it. It takes the same amount of time to access any location in RAM. CPU can perform two types of operations on Ram, these are:

  • Read
  • Write

Read operation:

during read operation the contents of memory location are copied to a CPU register.

Write operation:

During write operation the contents of a CPU register are copied to the memory location.

Memory chips are normally available as part of what type of card?

Memory Chips almost always come as part of a card called a MODULE.

Memory's usually listed with two numbers such as 8*32 or 4*16.

The first number represents the number of chips on the module, while the second one tells the capacity of each individual chip, measured in megabits(Mb) or one million bits.

Why is it still necessary to learn about older memory technologies when new motherboards are equipped with only new types of memory?

same reason why its necessary to learn about anything in the past. To move forward, the same methods and processes in the old can often be used to develop new technologies. Also, I think its just a filler in university courses when they cant think of anything else to teach.

What is RIMM slots?

its a rambhous inline memory module. its a type of memory slot which has beed used earlier.. now a days we are using dimm slots (dual inline memory module)..

What are the benefits of using cloud RAM for optimizing performance and scalability in a virtual environment?

It allows for efficient resource allocation and management, leading to improved overall system performance and flexibility to handle varying workloads. Additionally, cloud RAM offers cost-effectiveness by reducing the need for physical hardware upgrades and maintenance.

What is ROM in a computer and how does it differ from other types of memory?

Read-only memory (ROM) in a computer is a type of non-volatile memory that stores data permanently and cannot be easily modified or erased. Unlike random-access memory (RAM) which is volatile and temporary, ROM retains its data even when the computer is turned off. ROM is typically used to store essential system software and firmware that is necessary for the computer to function properly.

What is a page in memory and how does it function within a computer system?

A page in memory is a fixed-size block of data used by a computer system to store and retrieve information. It functions as a unit of storage that can be easily accessed and managed by the computer's operating system. Pages help the computer efficiently organize and transfer data between the main memory and the storage devices, improving overall system performance.

What is the difference between memory address and memory addressability?

A memory address is a specific location in a computer's memory where data is stored. Memory addressability refers to the maximum amount of memory that a computer system can access and use. In other words, memory addressability is the range of memory addresses that a computer can access, while a memory address is a specific location within that range.
