What is a byte and how many bits does it contain?

A byte is the basic unit of information in a computer. It is usually the smallest addressable object in memory. The size of a byte is a function of the design of the computer, but nearly universally, it has come to mean 8 bits. (Octet is a more precise definition of 8 bits of memory, in case there is any dichotomy.)

What does low page pool memory mean?

paging file is being filled ... get more ram and HDD space.... page file should be 1.5 the size of your ram... if it is constantly being accessed and over used get more ram....

How much RAM is factory installed in a Mac Book?

The amount of RAM that is factory installed in a MacBook depends on the model of MacBook. In the latest models (May 2013), the 11 and 13-inch MacBook Airs have 4GB of 1600MHz DDR3L memory factory-installed, and the 13 and 15-inch MacBook Pros 4GB of 1600MHz DDR3 memory, all four models being configurable to 8GB. The 13 and 15-inch MacBook Pros with retina display, however, have 8GB of 1600MHz DDR3L memory factory-installed, this configurable to 16GB.

What are the types of computer according to size?

Computers Types and Uses

SMALL (portable)

  • Palm computer / PDA / Iphone / linked phones --- remote access and applications; internet
  • Notebook computer (smaller version of laptop) --- remote data retrieval; internet
  • Laptop --- home, business, or remote location computing; networks; internet

MEDIUM (fixed)

  • Desktop computer (PC) --- Home and office applications; data storage; networks; internet
  • Workstation --- larger version of PC, network and server access and support
  • Server --- operating system, network base, data and automation operations

LARGE (room size)

  • Mainframe --- commercial information management, data storage and processing
  • Supercomputer --- scientific research, intensive data processing (e.g. military logistics, weather forecasting, astronomy)

What is memory contention?

Memory contention is a state a OS memory manager can reside in when to many memory requests (alloc, realloc, free) are issued to it from an active application possibly leading to a DOS condition specific to that application. Memory contention is typically not caused by a memory overflow by all joined allocation requests but rather by the frequency of joined reallocation requests issued! Is is not about the joined memory size allocated but about the reallocation request queue size that overflows! A typical symptom of an application suffering memory contention and therefore not anymore being served memory management requests by the operating system, is that it unexpectedly shuts down without any form of notification.

What is magnetic bubble memory with diagram?

Magnetic bubble memory is a type of non-volatile memory that stores data in the form of small magnetic domains, or "bubbles," within a thin film of magnetic material. Each bubble represents a binary digit, with the presence or absence of a bubble indicating a 1 or 0. These bubbles can be moved and manipulated using magnetic fields, allowing for data retrieval and storage. A simple diagram would typically show a magnetic film with bubbles represented as small circles, alongside arrows indicating the magnetic field direction that controls their movement.

How do you put sony M2 card in to SD slot?

Very Easy! You don't.

M2 Card's and SD Cards are physically incompatible with each other. M2 and MicroSD cards come from competing companies so finding a card reader that supports both are pretty easy and cheap to come by :)

How do you download the songs on bee mp3?

You have to click on the song then it will take you to another page, listen to the song then click download to my computer. Then plug your Ipod or mp3 and transfer it. Or you can put it in you i tunes.

Are RIMM and DIMM interchangeable?

You can not use RIMM memory in a DIMM type Motherboard, or vise versa. Although they pretty much do the same job, they work in different ways.

Is there a performance difference between having 2GB of RAM than 4GB?

All other things being equal, yes, there would normally be improved performance. RAM is Random Access Memory...this means it is the area of the computer memory that is used by the central processing unit (CPU) to store data and calculation results while it is processing input ready for output. It all happens very quickly. The size of the RAM governs the amount of data that can be processed at any one time. If the RAM is full of data at any time, other data has to wait in a queue until some space become available.

The processing of moving images is particularly 'RAM intensive' and games with graphics might not perform too well if there is insufficient RAM.

Is the human memory a certain size?

"The human brain contains about 50 billion to 200 billion neurons
(nobody knows how many for sure), each of which interfaces with 1,000
to 100,000 other neurons through 100 trillion (10 14) to 10
quadrillion (10 16) synaptic junctions. Each synapse possesses a
variable firing threshold which is reduced as the neuron is repeatedly
activated. If we assume that the firing threshold at each synapse can
assume 256 distinguishable levels, and if we suppose that there are
20,000 shared synapses per neuron (10,000 per neuron), then the total
information storage capacity of the synapses in the cortex would be of
the order of 500 to 1,000 terabytes. (Of course, if the brain's
storage of information takes place at a molecular level, then I would
be afraid to hazard a guess regarding how many bytes can be stored in
the brain. One estimate has placed it at about 3.6 X 10 19 bytes.)"

What is a track on magnetic tape?

Two recording schemes are common one use seven bit bytes per character and other using nine bit bytes. This means that the magnetic tape surface is divided into seven or nine tracks.The area in which data and information are stored on magnetic tape.
