3. What activities are performed while booting the operating system? The CPU accesses the BIOS even before the operating system is loaded. The BIOS then checks all your hardware connections and locates all your devices. If everything is OK, the BIOS load the operating system into the computer's memory and finish the boot-up process.

A user has opened a word processor, typed the numbers 123456789, and stored the document as a file called report1.
The speed of a NAS varies depending on the unit you have but are typically one gigabit with an Ethernet connection. This can be changed to run with 10 gigabit by adding a PCI-e network card making a fiber optic connection. A NAS made with an old computer may be limited to a 10/100 megabit speed connection. Capacity range in a NAS also varies depending on the unit you have, most store bought NAS devices comes with 1TaraByte to 4TaraBytes of storage capacity. The units that have more than 1 Terabyte uses multiple hard drives.

Memory Management Phillip Schepok POS/355 August 18, 2014 Paul Rouk Memory Management Computers are everywhere. The daily lives of the human population are constantly in use of a computer, or some sort of electronic equipment that is ran from some sort of technological computer. People may not realize that everyday things that help us live our daily lives are surrounded by electronics or computers. The alarm clock to wake you up in the morning, the coffee maker with a timer, the microwave to warm your oatmeal, the television, the automobile, the cellular phone, and the desktop or laptop computer all plays an important factor in our livelihood. To have these working computer electronics one must realize there must be some program to make these products work.
The brain and the computer brain use different kinds of memory for different tasks. Long-term memory is the main function of the human brain. Long-term memory stores information for years and makes it available the moment that it is needed. Computers use a form of long-term memory, which is a hard disk. The hard disk works sort of like a record: the record (platter) spins on a “spindle” and the arm moves to different sections on the record to read or write to it.
