Hallo,

A MAC ID is a hardware ID. Most devices like video card, modems, communication adapters and other add-on devices all have a unique ID. It is usually created at the time of manufacture and cannot be changed.

An IP address is an address on a network that identifies that computer on the network. IP addresses are assigned by the network administrator (or automatically by a router. IP addresses are not permanent. If you have a laptop, then your IP address when connected to your home network will be different from the IP address you have when you connect to your office network.

Hello john,

There are The different types of backup methodologies.

► Normal Backup:-This is default backup in which all files are backed up even if it was backed up before.
► Incremental Backup:-In this type of backup only the files that haven�t been backed up are taken care of or backed up.
► Differential Backup:-This backup is similar to incremental backup because it does not take backup of those files backed up by normal
backup but different from incremental because it will take backup of differentially backed up files at next time of differential backup.
► Copy Backup:-This type of backup is which is used during system state backup and asr backup. It is used in special conditions only.
► Daily Backup:-This type of backup takes backup of only those files that are created on that particular day.
► System Backup:-This type of backup takes backup of files namely, Boot file, COM+Class Registry, Registry. But in server it takes
backup of ads.
► ASR Backup:-This type of backup takes backup of entire boot partition including OS and user data. This should be the last
troubleshooting method to recover an os from disaster.


Thanks,
Shemeer

Hello John,

There are 7 fields in /etc/passwd:
<username:x:UID:GID:comment:home directory:shell>
Username
Password
UID
Primary group ID  Comment /description Home directory path Shell assigned to the user.

And the "dmesg" command can be used to display the system messages during boot time.


Thanks,
Shemeer

hello sir


An on premise business VoIP phone system is where the PBX, is both an IP system and resides right on premise.  This IP-PBX will most likely be an Asterisk system, but could be a more traditional PBX companies' IP-PBX, as well.  The advantage of an Asterisk IP-PBX is cost, open source and having a business phone system that escapes the traditional cycle of having to replace the entire system for upgrades or expansions, because the proprietary manufacturer wants to keep you buying entire new systems.  An Asterisk on premise system has all or more of the advantages of Hosted VoIP with on premise signaling, which is much more reliable, a lower total cost of ownership when measured over 3 to 4 years, plus the ability, in many cases, to expand the system or add extensions at a fraction of the cost of other systems, including Hosted VoIP.

thanks

Hello john,

Kernel is used in UNIX like systems and is considered to be the heart of the operating system.
It is responsible for communication between hardware and software components.

Its activities are:
1. The Kernel task manager allows tasks to run concurrently.
2. Managing the computer resources: Kernel allows the other programs to run and use the resources. Resources include i/o devices, CPU, memory.
3. Kernel is responsible for Process management. It allows multiple processes to run simultaneously allowing user to multitask. 
4. Kernel has an access to the systems memory and allows the processes to access the memory when required. 
5. Processes may also need to access the devices attached to the system. Kernel assists the processes in doing so.
6. For the processes to access and make use of these services, system calls are used. 

These are the main activities of a Kernel.

Thanks,
Shemeer

hii,

An IP Address is a numeric representation of a device (computer, game console, etc.) on a computer network
that uses TCP/IP to communicate (the logical connection of most of the internet).

A MAC Address is a numeric representation of a device (computer, game console, etc.) on a computer network
that uses Ethernet to communicate (the physical connection between most computers and routers).

On a computer network, computers communicate in layers.

If a software program on computer 1 wants to send a message to a software program on computer 2, the following translation happens.

The software application on computer 1 finds the logical (IP Address) of a machine and tries to send a message to it.
Computer 1′s operating system takes this logical message and finds the physical hardware location of this device
and sends the message to this device.

On Computer 2, the Operating System receives this message, unwraps the message and decides if it is also for the correct logical location.  If its the correct logical location as well, it unwraps the original message and sends it to the program waiting for this message.

This is a simplified explanation, but serves our purposes for now.

Thanks,
swetha.
