Memory it is a component found inside the CPU attached to the motherboard in its slot and held firmly by the help of the locking slatch on those slot. It act as stimuli (it stimulates the speed of motherboard).
In memory it has the power of keeping facts e.g data. In a process when you want to save data in system disk which has low or weak memory it may not save rather it will complain e.g. not enough memory and if managed to save it will not save well. In the case of saving job, memory and disk works together. Disk cannot work in absence of memory neither memory and disk works together. Disk cannot work in absence of memory neither memory in absence of disk especially hard disk.
In commensurable between human being and computer science, the brain acts as the memory of the computer system.
TYPES OF MEMORY
We have two major types of memory in used includes the RAM and the Rom but we are going two emphasized on ROM, RAM, and CACHE types of memory.
RANDOM ACCESS MEMORY (RAM):- This type of memory can be manipulated in some ways. Example it can be replaced in a system because, information are not saved directly into it. It can also be interrupted from saving information as a result of power failure that is why it is highly recommended to be saving data or files at least in every 2 to 3 minutes during typing.
TYPES OF RAM
Two types of RAM they are DIMM and SIMM
DIMM: Dual in line memory module.
SIMM: Single in line memory module.
Furthermore, there are also two types of DIMM, which are SDRAM and DDRAM
SDRAM: - is the type that has two notches or cut at its edge connector.
DDRAM: - is the type that has single notch or cut at its connector Both SDRAM and DDRAM has the same length and numbered of 168pins but can be differentiated by their notches or cuts.
SIMM:- this is the smallest type of RAM, which has single, or no cut at its edge connector and varies in sizes of its smallness.
Some SIMM have 72 pins while DIMM have 168 pins.
Read Only Memory (ROM):- It is the type of memory that has all information contained in it ready made. In this case the information are unalienable and can’t be interrupted by power failure.
Typical e.g of this type of memory is the AMBIOS (America mega trend incorporated basic input system)
BIOS:- Is the Rom type of memory that contains every information about the motherboard. Bio incorporated has a back up semiconductor like metal that conduct and store current for its purpose of operation known as Coms battery are:- the data and time of a computer system, just as the case A wrist watch and nay new changes that is made in it e.g enabling or disabling of a hardware etc while other information remain stable. This is so called Coms battery (complementary mental oxide semiconductor) can be located on the board, can be changed when it run down just for efficient and smooth running of the bios information and entire system.
CACHE: - a fast Ram system specially designed to hold information that the microprocessor is likely to use the cache is segmented into two in some Pentium computer and other higher processor, which are L1 and L2 cache. L1 cache is used for instructions or code and command while L2 cache is used for data the microprocessor carries the ranges of the computer e.g 233,300,500,1.0 etc and it is the major system component because it read, interprets and also carries out Arithmetic and Logical operation for the system.
The processor or CPU is the brain of computer. CPU come in various sizes, speed and packaging format. In processor we have Intel chips, they are the ones, which PCs are generally based.
Socket and slots: Chips are fit into socket or slot. Slot one was used for introducing of (P3) processor.
COMPLEMENTARY METAL OXIDES SEMICONDUCTOR (CMOS)
Complementary Metal Oxides Semiconductor (CMOS) is the name of battery found on the motherboard which helps in saving changes made in the bios setup or environments. When CMOS battery encounter electrostatic discharge will automatically become complicated with the bios changes saved by it. When CMOS encounter electrostatic the board ceased from coming up.
To help CMOS regain its strength, stop ceasing the board and charge back to hold information. To clear the information the CMOS is carrying, by removing jp4 cap and stay about 3 to 4minuites before putting on the pc if the board eventually came up the system and complain press “f1” this is for you to resave what you had cleared for and for the pc to start to run its normal way. To clear CMOS memory it mean that you don’t want the battery to retain what it is saving, just like a wrist watch battery when remove from a watch will take time not to function any more.
