61. Minimum Requirements for installing Windows 2000 Server as specified by Microsoft:
- Computer/Processor: 133 MHz or higher Pentium-compatible CPU
- Memory: 256 megabytes (MB) of RAM recommended minimum [4 gigabytes (GB) maximum]
- Hard Disk: 2 GB hard disk with a minimum of 1.0 GB free space.
- CPU Support: Windows 2000 Server supports up to four CPUs on one machine
It is always better to add additional resources that what is minimum recommended for better performance.
62. Internet Information Server 5 is bundled with Windows 2000 Server products. Windows NT 4 supports Internet Information Server 4, which needs to be installed through an Option Pack CD.
63. Windows 2000 provides the following tools for monitoring resource usage on your computer:
- System Monitor: With System Monitor, you can measure the performance of your own computer or other computers on a network like A)Collect and view real-time performance data on a local computer or from several remote computers.
- View data collected either currently or previously in a counter log.
- Performance Logs and Alerts: With this feature, you can present data in a printable graph, histogram, or report view.
64. 100BaseT (Fast Ethernet) uses IEEE803.2u standard which incorporates CSMA/CD protocol.
65. Grandfather-father-son (GFS) and Tower of Hanoi are two good rotation schedules providing a long and varied history of file versions. Both provide comprehensive recovery capabilities.
In GFS, "Son" is the incremental or differential daily back-up, "Father" is the full weekly back-up, and "Grandfather" is the monthly full back-up.
Tower Of Hanoi:
Tower of Hanoi got its name from an ancient Chinese game using recursive techniques. In the game, you move a stack of disks from one of the pegs to another peg and a smaller disk can only be placed on a larger disk. Like the game, many multiple media sets are rotated through in incremental and full back-ups. It uses more media sets than GFS for increased safety.
66. Auto Loader: An autoloader holds ten to twelve tapes, and usually only one tape drive. This is useful when the data to be backed up is more than one tape's capacity. It allows the admin to program and attend to other important works than wait for changing the tape.
Tape Library: A Tape Library contains multiple drives in it. As a result, multiple backups can be taken simultaneously. This is useful when you need to take huge backups in short time. However, remember that if the backups are taken across the network, the network speed limitations will come into play.
67. Some of the important commands useful in trouble shooting TCP/IP networks are:
I. Ipconfig: Displays TCP/IP configuration values, including IP address, subnet mask, and default gateway.
II. Ping: This command can be used to verify whether the target ip address or host name is present. You need to specify the target IP address or host name.
III. route: Displays and manipulates route information.
iv: Tracert: Determines the route packets take to reach the specified destination.
68. DMI is used to automate system management and is particularly beneficial in a network-computing environment where there are many computers.
69. All the following operating systems use TCP/IP as their default network protocol:
- Unix/ Linux,
- Novell Netware 5.1
- Windows 2000
In the earlier versions of Windows, Windows NT3.51 or Windows NT4, TCP/IP was optionally installed. Whereas, in Windows 2000, TCP/IP is the default protocol.
70. Following are the hardware requirements recommended by Novell to install NetWare 5.1:
A server-class PC with a Pentium II or higher processor
A VGA or higher resolution display adapter (SVGA recommended)
Standard NetWare products and WebSphere Application Server for NetWare-1.3GB on volume SYS
RAM: Standard NetWare products-128MB
RAM with WebSphere Application Server for NetWare: 256MB (512MB recommended) in addition to standard NetWare products
A CD-ROM drive that can read ISO 9660-formatted disks;
A PS/2 or serial mouse is recommended, but not required
71. ACPI stands for Advanced Configuration and Power Management Interface. ACPI define working interfaces between the NOS (such as Windows 2000), the BIOS, and your system's hardware. The interface standard allows the Network Operating system, such as Windows 2000 to control power management.
- ISA is an acronym for Industry Standard Architecture,
- EISA is a acronym for Extended Industry Standard Architecture,
- PCI is an acronym for Peripheral Component Interconnect, and
- MCA stands for Micro Channel Architecture.
- CPU stands for Central Processing Unit.
- SCSI stands for Small Computers Systems Interface. It is pronounced as Skuzzy.
- DIMM stands for Dual-Inline Memory Module
- SIMM stands for Single-Inline Memory Module
- SRAM - Static random access memory - Uses transistors to store information
- DRAM - Dynamic random access memory - Need to be refreshed to retain data.
- ROM - Read only memory - Data in ROM can not be erased or changed
- PROM - Programmable ROM - Once programmed, data can't be erased or changed
- EPROM - Erasable PROM - Data can be erased by ultraviolet light and can be reprogrammed using a programmer.
- EEPROM - Electronically erasable PROM - Data can be erased electrically. Chip can then be reprogrammed. EEPROMs are frequently used to store BIOS.
