Random access memory is the Memory that enables the Computerz to execute the program. your computer needs a high ram for smooth and faster processing of data and running of programs with that it is common know that the higher the ram the faster the Computer computer vice versa. The capacity of RAM is measured in mbs and Gb where by 1,000mb is equivalent to 16b.
Computer memory or storage refers to as electronic hard ware component which are design to hold digital data within and out of the computer on temporary basis
Example of random access memory
1 dynamic RAM
2 static RAM
Dynamic Ram is to load the operating system, application when enytime system is on
Static Ram make the application and data with faster.

Things to consider when studying technology
Technology and computer are everywhere, there are not study to know where they are,but how to use them, this are the example of technology and how to use them.
Technology is how things are made, technology is how things are done.
Example of Technology
1. G. S. M: use more than one technology,one of the technology inside phone is Bluetooth technology, we have infared technology,bluetooth and infared work hand in hand but infared is the first technology them invented to phone s
After that we have Bluetooth as time goes on and Xander later came in..
G.S.M : Global system mobile. It is made to develop to move with eny device in the world
There is a certain roles that guard a device
1. Your phone cannot work without your sim,
The gold on your sim is the one that work with a phone
Example of different line of technology
1. Mechanical technology: is a design product and the use of machines that do not use electrical, electronic or computer devices of technology
2. Chemical technology: The world Chemical is from chemistry, when the science in chemistry is used to turn raw materials into move useful things like plastic, cusmestics, or drugs, this is called Chemical technology. Used to refine gasoline
3. Electrical technology: Technology that deal with electrical circuit and equipment is known as Electrical technology. It is commonly in the design in construnction machine and power grid
4. Digital Technology : information is recorded using combination of 1 to represent words and pictures,this system is slow huge amont of data to squeeze into tiny space
Example on that is digital cameral
5. Bio Technology : This is a study of living thing and non-living thing, it is commonly use in agriculture and food production
6. Medical Technology : is the everything is like tool machine process or substance that is use to diagnose, observe,treat ,cure or prevent people's illnesses or injuries
7. Information technology : is the study, design and the use of electronic information system
8. Nano Technology : is modern science used to create materials and simple machines much to small for your eye to see under a normal Microscope, this Nano technology used in product, special sunscene and textile.
Technology is how things are made, technology is how things are done.

Probems you look forward before install your computer or system
1. Faulty connections : these is a most common problem and it's include improper made cable connection to the board or drive
2. Switch fan another small component
3. The RAM slot not properly fix in
4. Improper settings this can be jumper or switch on the motherboard the voltage switch on the power suply
5. Software settings made in CMOS setup after initial power up
6. C. P. U voltage: improper C. P. U voltage or settings In some motherboard : improper software settings will general resolve in slower inconsistent operation
7. D. O. A Death on arrived port : This problem is less common you have to troubleshoot the death component
8. Incompatible selected port or poorly selected port : this best way to keep this problem is to buy the right thing you need
9. Carelessness : Dropping part to sleep off your hand, loosing the system without completing the loosing, to a laptop without removing the backup.

System software
System software is a set of software programm Thats help, run the Computer and cordinate imstructions between application software and the Computer hardware device.
System software consist of two primary program
1. The operating system
2. The utility software
Operating system
Operating system is the main program that control how your system function
functions of operating system (O. S))
1. The operating system manage the Computer hardware including processor,storage device as well as peripheral device such as monitor and printer
2. The operating system also provide a consistence means for software application to work with the processor
3. Operating system is responsible for the management scheduling and interacting of task such as refreshing of computer,opening a program as well as system Maintainance
Utility programs
Utility program are small programs that perform many of the general house keeping task for the computer such as system maintanance and file compression. Every 💻 from the smallest notebook to the largest has operating system even tiny personal digital assitance (pda) as well as small compiler has a operating system. Computer cannot operate without operating syatem

How to format a system on window xp
U notice your hard need to be formatted, and the OS which mean operating system is window xp, all u need to do is to get the software
We have service pack2 xp, service pack3 xp, u may c on the paper of the soft ware bootable disk. This window xp bootable disk is use to format a system with window xp.
Insert this bootable disk inside ur disk drive after u might have inserted UR disk UR system is booting, u can format your system before booting to window u can format as well after booting finish is either of the two. But if u want to format from scratch I. E before it enter window u will c setup and boot menu, your system will ask you to press eny key mostly HP system uses f12 for there boot menu but depend on the manufacturer of a system,look carefully when your system Is booting and press the key, the next step will b Press entry to continue and select boot from CD. Press enter to setup window.
A new page aPpears with A list of a options on where to Install the hard disk and in this point u can Press o to delete the hard disk.at this process will take you back to the initial screen if where to install windows.
Press c to create a new partition on the hard disk and select the size to use on the future show there in and press enter
Choose the new partition as the primary partition to install windows in and select NIFS/FSD as fast and secure
Thereafer window will b formatted and hard disk process with the installation.

How to build a system
Few things ar to put in place when building a new system.
1 The case of a system in most cases we do have power supply unit(p.s.u)
2 we need the motherboard in motherboard we do hv processor inside.
3 The RAM random access memory also needed when building a system.
4 The HDD hard disk drive is very essential as well cos all our information data and all save document are save on the hard disk drive permanent
5 keyboard
6 mouse
After getting all this mount the motherboard inside the case of your system. Connect All the necessary wire from the power supply unit to the motherboard that is the p1, p2 as well give the motherboard energy, connect the hard disk drive will b need to be need to be connected as well, then mount the RAM inside. This RAM works as a PA of a processor collect Information for processor and from it the processor give the user. After that cover the system very well and plug it. Then switch on your computer.
