Explain the function of the different system unit component and how they communicate with each other with diagram. The control circuitry pulls data in via the various ports, directs it along data buses, stores it within the memory, performs calculations on it and sends the results of processing to a VDU screen, to a printer or to a secondary storage device for more processing at a later date.
Task 2: P2
give people a totally free alternative to Windows
formatting the device in the ext2 filesystem on a single partition and making it work. This is intended for situations where the device will be used exclusively on Linux machines;
formatting the device on a dual partition in the ext2 and vfat filesystems and making it work. The purpose of this is for situations where Linux + Linux and Linux + Windows are possible;
making the device more user friendly;
maintaining the filesystem of the device;
using additional features of Linux-2.6.x.
Linux has evolved to have the following features as an outstanding operating system which is strong in security and networking.
â€¢ Multitasking: Several programs can run at the same time.
â€¢Multiuser: Several users can logon to the same machine at the same time There is no need to have separate user licenses.
â€¢ Multiplatform: Linux runs on many different CPUs, that means it supports multiprocessor machine.
â€¢ Multithreading: Linux has native kernel support for multiple independent threads of control within a single process memory space.
â€¢Crash proof: Linux has memory protection between processes, so that one program can't bring the whole system down.
Linux has CD-ROM file system which reads all standard formats of CD-ROMs.
Linux performs well with TCP/IP networking, including ftp, telnet; NFS
Linux is user friendly as Netware client and server
Linux also runs as Lan Manager/Windows Native (SMB) client and server
Linux also runs as Lan Manager/Windows Native (SMB) client and serverÂ
Shared copy-on-write pages among executables: This means that multiple processes can use the same memory to run in. When one tries to write to that memory, that page (with 4KB piece of memory) is copied somewhere else. Copy-on-write has two benefits: increasing speed and decreasing memory use.Â
Demand loads executables: Linux only reads from those parts of a program that are actually used on the disk
â€¢Crash proof: Linux has memory protection between processes, so that one program can't bring the whole system down.Â
Linux has CD-ROM file system which reads all standard formats of CD-ROMs.Â
Microsoft Windows is an operating system for computers. It acts as an interface between the hardware and the user. The purpose of Windows is to improve on other operating systems by making it easy to understand for users of all backgrounds. It also try to make the best use of the computer hardware possible by managing its memory effectively.

Explain use of two different software utility: P3
Disk checkers can scan the contents of a hard disk to find files or areas that are corrupted in some way, or were not correctly saved, and eliminate them for a more efficiently operating hard drive.
Disk cleaners can find files that are unnecessary to computer operation, or take up considerable amounts of space. Disk cleaner helps the user to decide what to delete when their hard disk is full.
A routine maintenance task will be specified by your instructor:
1. Go to Start > Control Panel then click on scheduled tasks.
2. Click on add scheduled task then:
3. Select a program to use then click next.
4. Click on when the program will start. e.g. 3:45PM every Tuesday, or you can also make it start when you open up the computer.
5. When you have finished, click Finish.
To achieve G, explain the importance of undertaking the routine maintenance :
My routine maintenance consists emptying the temporary folders and files, uninstalling programs not being used anymore, and defragging. My computer does not get infected by spyware or ad ware surprisingly.
I use routine maintenance to avoid the risks of viruses and increase the speed of my computer and make it very useful. Is an essential part of running arising and to save time when diagnosing and fixing faults. It can also extend the life of your PC.
To achieve E, give an example of another routine maintenance task.
Use online tools to prevent viruses from infecting virus
Optimization system using the windows support tools
Regular disk defragmentation and disk files scanned
Task 5: M1
Install and configure the device provided by your instructor:
To achieve G, install and configure one device
To achieve E, follow all safety procedure during installation, you will observed by your instructor.

Keep the workspace clean
Keep most solvents area
Properly returned all the tools used for task
