how many bits of memory are in the second memory device? course hero

What are secondary memory devices?

Here we will discuss secondary memory devices that can be used to store large amount of data, audio, video and multimedia files. These are some characteristics of secondary memory, which distinguish it from primary memory −

What is the size of the hole in the memory?

However, if there are many holes and many calculation will also be small. Consider a swapping system in which memory consists of the following hole sizes in memory order: 10 MB, 4 MB, 20 MB, 18 MB, 7 MB, 9 MB, 12 MB, and 15 MB. Which hole is taken for successive segment requests of

How many programs can be stored in memory at once?

Second, with 4-bit keys, only 16 programs can be in memory at once (one of which is the operating system). In Fig. 3-3 the base and limit registers contain the same value, 16,384. Is this just an accident, or are they always the same?

How many bits does it take to represent a memory word?

The requirement is to represent each memory word with an address, which is in bits, in such a way that each and every word can be represented. For example, to represent 4 words, you need 4 addresses, 2 raised to 2 is 4, so you need two bits.

What is memory bus?

Memory bus can be thought of literally as lanes of traffic. More lanes dedicated for traffic, the greater the flow. The graphics processor is connected to the RAM on the card via a memory bus. As far as affects on gpu memory bus, I've seen mixed results.

How many memory chips does a 660TI have?

The 660TI is a 192-bit bus which normally will have 6 memory chips resulting in 1.5GB of memory.

How much memory does a 660TI have?

The 660TI is a 192-bit bus which normally will have 6 memory chips resulting in 1.5GB of memory. But in this case nVidia added 2 memory chips to the back of the 660TI 2GB to achieve this. The 2 extra chips shares the bus with 2 memory chips on the front side of the card.

How much memory does a GeForce 550 Ti have?

No wonder most of the 550 Tis on the market have just 1GB of memory. While Point of View loads the card up with high-density memory chips, they're not very fast ones. The GeForce 550 Ti is meant to be paired with GDDR5 memory with an effective data rate of 3.6 GT/s.

Is 128 bit faster than 256 bit?

There are actually some 128 bit memory bus cards that are faster than 256 bit memory bus cards. This is because memory clock speed can be different and so on. The actual important thing to look at is the memory bandwidth of the card, How many (GB/sec) it is.

Is DDR3 cheap?

That's perfectly fine if you don't really plan to play video games on it very often. DDR3 is cheap enough to produce anyways so I suspect that it was the best cheap option nVidia had for the price range. You want GDDR5? Pay for it. It's that simple.

What is secondary memory?

Such memory is called secondary memory. Here we will discuss secondary memory devices that can be used to store large amount of data, audio, video and multimedia files.

How much space does a CD have?

They are very cheap as you can get 700 MB of storage space for less than a dollar. CDs are inserted in CD drives built into CPU cabinet. They are portable as you can eject the drive, remove the CD and carry it with you.

What is a hard drive made of?

Hard disk drive is made up of a series of circular disks called platters arranged one over the other almost ½ inches apart around a spindle. Disks are made of non-magnetic material like aluminum alloy and coated with 10-20 nm of magnetic material.

What is a pen drive?

Pen drive is a portable memory device that uses solid state memory rather than magnetic fields or lasers to record data. It uses a technology similar to RAM, except that it is nonvolatile. It is also called USB drive, key drive or flash memory.

What is a BD disk?

Blu Ray Disk (BD) is an optical storage media used to store high definition (HD) video and other multimedia filed. BD uses shorter wavelength laser as compared to CD/DVD. This enables writing arm to focus more tightly on the disk and hence pack in more data. BDs can store up to 128 GB data.

Is secondary memory a volatile memory?

It is non-volatile, i.e. it retains data when power is switched off. It is large capacities to the tune of terabytes. It is cheaper as compared to primary memory. Depending on whether secondary memory device is part of CPU or not, there are two types of secondary memory – fixed and removable.
