Activity 5.2 Minimum system requirements for windows 2000·        133 MHz or higher Pentium-compatible CPU.·        64 megabytes (MB) of RAM recommended minimum; more memory generally improves responsiveness [4 gigabytes (GB) RAM maximum.]

·        2 GB hard disk with a minimum of 650 MB of free space. (Additional free hard disk space is required if you are installing over a network.)

·        Windows 2000 Professional supports single and dual CPU systems.

The computer running windows 98 can be upgraded to windows 2000NTFS:

·        Smaller RAM footprint as avoids large FAT held in RAM

·        Indexed design more efficient for many files per directory

·        Small file data embedded in dir level, avoids seek to data chain

·        Above factors make fragmentation less onerous than for Fat32

·        4k cluster size matches processor’s natural paging size

·        Transaction rollback cleanly undoes interrupted operations

·        File-level permissions can protect data against malware etc

.·        Automatically “fixes” failing clusters on the fly (controversial)

·        smaller cluster size than FAT32 above 8G

·        may include data of small files within the directory level

·        NTFS’s bitmap structure is smaller than FAT32′s dual FAT

·        sparse files and compression can reduce data space usageNTFS is unable to rollback to FAT32 

Recoverability – In the event of a system failure, NTFS uses its log file and checkpoint information to automatically restore the consistency of the file system by using standard transaction logging and recovery techniques.Compression – Files that are compressed on an NTFS volume can be read and written by any Windows-based application without first being decompressed by another program. Decompression happens automatically during the read of the file. The file is compressed again when it is closed or saved.4. Once NTFS is installed, can you revert back to FAT32 file system?Yes, you can revert back to the FAT32 file system. You can do this by using the Windows XP Startup disks or, if your computer supports a bootable CD-ROM, by using the Recovery Console tool on the Windows XP CD-ROM. Reformatting or repartitioning a disk deletes all of the data that is on the disk, so make sure that you back up your data before you reformat the disk.5. Should you use the Administrator account for normal use of the system?6. How do you set the start bar’s Auto-hide feature?7. How can you configure your computer to automaticlally adjust for daylight savings time?8. How do you remove unwanted third party application software?9. A client asks you to install a new package on her computer and gives you distribution media. Explain what you should do before installing the software?10. Microsoft Windows 2000 features.11. Describe how Microsoft products are now registered?12. What is the latest operating system offeres by Windows? Identify features

Can store data for a long period of time.2.       A Hard Disk Drive (HDD), a common form of secondary storage device due to its large storage capabilities and ese of use, can be used as a input and output device.3.       Peripheral devices are devices which are not essential devices that need to be connect in order for the PC to operate. e.g. printer, webcam.4.      Input device – Keyboard and Mouse.
keyboard – Used as a device to input characters into the PC, which process them as words, numbers, or be used to create macros.
mouse – a pointing device used to control by the user to access files by moving the mouse and clicking.5.      Circuit boards, video cards, cooling systems, power supplies and internal hard disk drives which are plugged directly into the motherboard.6.      . RAM is short term memory which temporarily holds data which may be called up straight away where as ROM holds data for as long the user may like. e.g. RAM storing internet websites and ROM storing spreadsheets.7.      A small program that is permanently stored on the hard disks runs automatically to load the operating system into the main memory (RAM) so that it can start using it.8.      A computer needs peripheral devices for extra memory or as a way of transferring data to other devices or to physical data i.e. paper.9.      A modem allows a computer to communicate with another computer using a standard telephone line10.  The three networking topologies are Star, Buss and Ring.11.  Router is a device that determines the next network point to which an information packed should be forwarded towards it destination. A server is a computer program that provides services to other computer programs on the same computer or on others computers.12.   File serves is a software that provides access to disks and other storage devices it allows users to store, save and retrieve files. A proxy server sits between a web browser and the real server. A printer serves is software that allows anyone on the network access to a printer, provided they are authorized.13.  An advantage of sending a print job to a print server is the user can press print and the data queues to be printer while the user can continue working without having to wait for it to print on a normal computer.14.  3 example of pointing devices 1) Mouse 2) light pen 3) joy stick]15.   A parallel port allows you connect peripheral devices with a parallel cable whereas a serial port allows you to attach devices like modem to you PC. A few example of serial port devises are, mouse, modem and keyboard. A few examples of a parallel port device are scanners, and printer.16.  A SCSI is a fast communication bus that allowed you to connect multiple devices in to a daisy chain configuration to you PC.
