Computer Memory
The computer memory is a physical device used to store data or programs for use in a computer. Some types of computer memory include RAM (random access memory), ROM (read-only memory), and page cache.

When you reboot your system the computer follows startup instructions stored in this type of memory?
On start up the computer fetches information from BIOS. BIOS is a ROM. After that the computer loads OS from Hard disk into the RAM.
3 groups of hardware components?
Three groups are Input, Output and Processors. Here are a few examples:
INPUT
Microphone
Scanner
Webcam
OUTPUT
VGA
Printer
Speakers
Processors
CPU (central processing unit)
What is 2Rx8 PC2-5300S in memory terms?
2r is corresponding to a "duel rank" module as opposed to 1r "single rank".
x8 (by 8) configuration is corresponding to the industry standard low density memory configuration. If the module was listed as a 1rx4 it would be corresponding to a "single rank" x4 (by 4) high density module.
5300 is corresponding to the speed of the module itself. PC2-5300 or PC5300 both correspond to the speed, which in this cause is a 667Mhz module. If it were a PC4200 it would be 533Mhz, PC6400 is 800Mhz.
PC2 is corresponding to how the manufacturer labels the product. PC2 translate to a DDR2 module, however you will find DDR2 module labeled both PC2 and PC, it depends on the manufacturer/seller. The reason for this is because DDR memory maxes out at a PC3200 speed (however there are also DDR2 PC3200 speed so you have to watch for that). If a module is listed as PC4200 and up it is a DDR2 module and having the "PC2" labeling is unnecessary, as they will always be DDR2.
5300S: The S does stand for "SODIMM" memory which is notebook RAM. If you saw a module that was PC5300U, the U would stand for "unbuffered" memory. There are various others like "FB" (Fully Buffered), "R" (registered) etc.
First go into CMOS setup and disable the internal device.
What is the best system and memory for a home computer?
Most computer users will be happy with a 1 gigaHertz processor with between 512 megabytes and 1 gigabyte of Random Access Memory on the motherboard. This is more than adequate for almost all applications.
Why does RAM accesses data randomly?
RAM stands for random access memory.so due to this it takes data randomly.
What is the objective of cache only memory architecture?
Cache memory is the high speed memories which are repeatedly requested by the Cache client (CPU). Whenever the requested data from the cpu is present in the cache, it directly supply the data and is known as cache hit(fast) and when the data is not accessible in cache then cache access the block of the main memory and feed to the CPU and it is termed as cache miss (slow).
What types of operands are typical in machine instruction sets?
Addresses, Numbers, Characters, Logical Data (source: Computer Organization and Architecture, William Stallings)
Count either number of occurrences of a certain event or ticks of a clock signal.
- count decay events of a radioisotope sample
- count floors passed by an elevator; note: this counter needs to be able to count both up & down
- count persons passing through a gate/turnstile
- count seconds, minutes, and hours to record current time
- count pages printed by a printer
- count instructions executed in a computer program; maybe needed in some timesharing OSs to compute machine usage for billing of users
- count bytes/words of memory fetched for instructions; this is also called a program counter or instruction counter and keeps track of the next location to fetch from in memory
- count ink drops used in a printer cartridge to estimate how much ink is left
- count distance a vehicle travels, also called an odometer
- etc. etc.
Some counters are loadable with arbitrary values some are not. Most but not all counters can be reset to zero.
How much memory is needed to store 1 character?
one character = 1 byte
write abcd......z in notepad and save it to your desktop in filename xyz.txt
Now right click on file xyz.txt and click on property, u will notice that file size will be 26 bytes...because we have 26 characters in english letter, and computer requires 1 byte per character.
space also requires 1 byte
DDR2 and DDR3 are both 240 pin DIMM.
They have a special notch so as to keep you from putting one where the other belongs.
What does maximum address by a poniter refer in TC and GCC compilers?
In turbo C pointer maximum refers up to 1MB of memory, wheras in GCC pointer refers up to 4 gb of memory.
What should the minimum spec requirements on a laptop be for you to run your dsl msn premium?
Minimum of 650 MHz Processor Speed Minimum of 64MB of RAM (128MB recommended) Minimum of 125MB of free hard drive space CD-ROM or DVD drive Win98/ME/2000/XP
How much video RAM needed for 800x600 image in 64000 colors?
The minimum is actually about 2 MB, but those don't exist anymore so you can pretty much look for any graphics card.
Is the DDR2 a type of RAM memory used most often in today's computers?
DDR2 RAM is not the standard anymore. Until about 2007-2008 it was very commonly used. Today DDR3 is the standard RAM. Though DDR4 is in the works and will debut sometime soon.
What is Random access storage?
Random Access Memory (RAM) is not used for storage. A random access storage device is the hard drive, where data can be stored and accessed randomly. Any data on the volatile RAM is lost when the computer is switched off.
What feature is used on memory slots and modules to prevent modules from being inserted incorrectly?
A small plastic piece within the slot, which matches the small cut on the RAM chip. -Chris Arbeene (Inaiá Rossi)
How is the term wheelhouse used?
Baseball: The optimum position of a pitched ball so as to allow a batter the best possible swing. The best position for a pitched ball to be hit. (i.e. "The pitch was in he batters wheelhouse" ) Hockey: the best placement of a puck so as to allow a strong shot. (i.e. "The puck was in his wheelhouse when he shot it.") In general: the optimum position for anyone to use their talents most competently. Maritime: The ships cabin. The place where the ships steering mechanism is located.
Draw the block diagram of ram and explain its operation?
Memory is technically any form of electronic storage. Personal computer system have a hierarchical memory structure consisting of auxiliary memory (disks), main memory (DRAM) and cache memory (SRAM). A design objective of computer system architects is to have the memory hierarchy work as through it were entirely comprised of the fastest memory type in the system.
How much Ram and Rom does the computer system have?
If I was to purchase a computer that is a average desktop computer how much RAM and Rom should I have?
