In CPU, we find the following components:




 The math processor or numeric




Microprocessor is an optional installation, also known as floating-point unit microprocessor
which aids in the efficient use of graphing software, math and design of many complex, which to
specialize these functions accelerates the speed with which a computer can answer
sophisticated needs.




They already are included in all new computers, because the power demand can not rule out
the absence of a microprocessor. If you want to know if your computer has one, just see if the
model has added the letters in the DX Otherwise, you will need in the immediate future
installation.




Above all there is no question if your machine instead of the other pair of letters presented as
SX, for example: 486 SX 25 Mhz.




                                                                                              1/8

If you need to install one, you must first make sure that:




1. Have your motherboard has a slot available for the specific math coprocessor.




2. That it is selling the same brand that your computer Microprocessor Core




3. To work at the same speed as the microprocessor makes it his main computer. that is, if you
have a PC 486 SX 25 Mhz, the coprocessor must be a 487 SX 25 Mhz. As you can see the
coprocessor is something like half the full microprocessor.




3. Memory




It is the ability to store information, which is performed in separate banks of the PCU. Your
storage unit is the byte which is the ability to store one character: a letter, number or symbol as
#,$,&, etc.




Types of reports:




                                                                                               2/8

ROM




This memory is read-only, and is used to store the basic program of initiation, installed from the
factory. This program falls in line as the computer is turned on and their first function is to
recognize the devices, (including working memory) devices.




RAM




This is called random access memory or can also be read as it can be written, has the
characteristic of being volatile, that it only operates while the computer is turned on. It is stored
as instructions that you need to run the microprocessor as the data you enter and want to
process, and the results of this.




Therefore, a program to be run on the computer program that maximum should be the same
size as the capacity of this memory, otherwise it will be unable to run.




NOTE: When you see the need to purchase a computer program, or whatever it is, well read the
instructions before paying, because they should clearly specify the minimum amount required to
be taken to your computer work with it.




                                                                                                 3/8

System Requirements.




As you can see if when you turn off your computer are volatilized our data stored in RAM, we
need therefore, means that storage for an indefinite time we ensure the safety and reliability of
our data, or other reports.




It is now available on memory cards up to 512 Mb RAM and costs vary. Below is a table with
the current prices of memory in RAM.

Auxiliary Memory




For the characteristics of the use of the ROM and RAM management, various data storage
media, among the most common are:




                                                                                         6/8

 They are like the audiocassette tapes and can store from 20 MB to 2 gigabytes or more. They
are very inexpensive storage media, and above all very fast, because they can store an entire
hard drive on a small cassette in a few minutes.
