Computers Technology Concentration

Memory schemes are defined as the types of memory used by the system to perform various tasks. Basically two types of memory are required to perform all the data handling and computing applications, namely ROM and RAM.

In contemporary usage, memory usually refers to a form of semiconductor storage known as random-access memory (RAM). These are light, small sized but quite expensive at the same time. They lose information when they are not powered. As RAM is a volatile memory a computer only having RAM would not have a source to read instruction from. So a computer needs a non-volatile memory to bootstrap it to the computer which is useful at the time of the starting of the computer.

In case of a computer the task of booting is provided to the Read Only Memory (ROM). ROM consumes a lot of space and it is more expensive. Therefore in case of laptops a bootstrap is used instead of ROM. The function of bootstrap is to command the processor to load the system files required during booting into the RAM. Then the files such as io.sys and boot.sys act upon it to gather the information required for booting.

Hard Disk for Laptops and Computers: The type of hard disks to be used in case of the computer depends entirely on the type of usage. In case of laptops there are not much of options due to shortage of space. The different types of hard disks include 3.5’, IDE and SATA interfaces whereas in case of laptops the available modules include 2.5’, 1.8’, IDE, SATA and SCSI. Hard disk comes in different memory sizes starting from 60GB to 320 GB for laptops and 120GB to 1TB for computers. The life of the hard disk depends upon usage, power supply and type of files it holds.
