What's a network administrator?
A Network Administrator could also be referred as System Administrator. A Network administration tasks on a small business system include installing and configuring network workstations, creating and maintaining user accounts, backing up the system, distributing software across the networked workstations, and providing end user support. Each of these tasks serves a specific purpose in the administration of a networked system. However, one task can have an impact on several other tasks. In order to gain insight into how these tasks are interrelated, they are commonly grouped into functional areas. Network Administration is a never-ending operations issue. * There are five basic network administration functions: •Fault management •Configuration management •Accounting management •Performance management •Security management Active Directory gives network users access to permitted resources anywhere on the network using a single logon process. It provides network administrators with an intuitive, hierarchical view of the network and a single point of administration for all network objects. Monitoring the health of hard drives on networks in enterprises is also a fairly important issue. Repairing a computer after a hard drive failure can take a lot of time of highly qualified and expensive personnel. Network administrators can configure the parameter for notifications about the dangerous state of hard drives. Such notifications can be sent over the network (similar to net send...) or by e-mail, which makes monitoring as remote as you need it. Network Administrators use tool to inventory computers in the corporate networks for the software and hardware configuration, generate software licenses reports, etc. Allen(*) We could learn a lot from crayons: some are sharp, some are pretty, some are dull, some have weird names, and all are different colors but they all have to learn to live in the same box.
What is the difference between a network administrator and a network engineer?
The best way to highlight the difference is to draw a parallel with a simplification:Network administrator - keeps the lights onNetwork engineer - designs the lighting solution and makes sure it works right
What are the main responsibilities of a database administrator?
DBAs “own” the operational aspects of the data world. At a minimum, they usually do the following:Installing and configuring new database instances.Setting up and maintaining “disaster recovery” strategies, which can be anything from a nightly backup to replicated redundant servers doing live replication with backup instances in both local and remote data centers.Managing db access by creating users and generally managing db-level authorization and data access policies.Monitoring db-level aspects of performance, and configuring and managing db-level configuration parameters that relate to instance-level performance, such as buffer pool configs, lock manager configuration, etc. Even relatively “simple” DB engines like MySQL have dozens of parameters - Oracle has hundreds - that can be tuned, and good DBAs know how to monitor and tune these.Related to the above, monitoring queries on the dataworld and helping with individual badly-performing queries by using EXPLAIN and working with developers to add indexes and refactor queries so they can run more efficiently.Many DBAs have additional roles and duties, particularly in smaller shops and startups:They often have general system administrator roles as well as DBA roles, and they often end up “owning” the hardware and software stack involved with the dataworld, such as the DB servers and any SAN devices or other storage systems in the environment.If cloud environments are used, DBAs need to know about managing dataworlds in the cloud environment.Really good DBAs can evolve into data or system architects, particularly if they take a strong interest in applications using the database and get good at advising developers on ways to efficiently design schemas versus simply waiting for problems to show up on production and reacting to them.Sadly, many organizations don’t encourage this very well as DBAs are usually regarded as “operations people”, and are organizationally distant from people who actually create schemas and queries, so if you want to become this type of “architect-level” DBA, you have to make an effort to reach out and work with developers and engineering teams in your company when they’re designing their software - and before the bad schema or bunch of slow queries show up on production.
What are the things every network administrator should know?
Here are things a network administrator should know:1. What technology and software they are using in the company2. What are the strengthens and weaknesses of the technology and software3. What is the budget in regards to IT.4. What is the most effective way to increase productivity with the hardware and software without hindering the IT budget, or the necessary things to run the business. 5. A baseline of the system, to look for security holes, and other issues that may result in the present or future. This will also include how easy would it be for outsiders to hack the system.6. The best way keep the system secure.7. The previous documentation of the last administrator setup when planning on building the current system.8. How old the technology is, and when it will be out of date.9. The best way to reduce the cost of running the software and technology, such as outsourcing it as much as possible. Many times money can be save, but not always. The main thing is to keep quality when doing so, as this is the most important.10. A good future outlook, to help the company plan better, such as a plan for 4-6 years from now. 11. How to monitor all the traffic on the network in an efficient manner.12. The best way to make the system as easy as possible for non-technical users, without harming progress, or efficiency. 13. How to relate to everyday people, such as clients they will help troubleshoot issues for, business leaders, HR, etc.I could go on, but I am not sure if you are a system administrator, or that you plan on hiring one, but these are some good questions to ask. This is only touching the surface, I could go into the more complex parts, but for now this will suffice. If you are interviewing, bring in a person or a group of people that knows the system well, such as your PC techs, or anybody else that knows the system. Also, make sure you test them, such as a probation period to see if they know what they are doing, it is easy to appear as if you know what you are talking about, but unless you have the skills to back it up, then it is futile. If you have any other questions, ask.
I set an administrator password on my hp mini 110 that forgot, how do i get in my laptop?
You forgot to tell us what password. Is it a bios password or windows password? For Windows Password, As far as I know , there are two main methods to solve the windows password problem as follows: 1st Method: Start system and when you see Windows Welcome screen / Login screen, press ctrl+alt+del keys twice and it'll show Classic Login box. Now type \Administrator\ (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows. Now you can reset your account password from \Control Panel - User Accounts\. Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen. 2th Method: Windows password Recovery software: for example:Windows Password Recovery Tool 3.0 . It is easy and convenient to use. http://www.windowspasswordsrecovery.com For Bios Password, also two methods. 1st method . Open you computer box and Discharge to the Board manually 2st method . use BIOS/CMOS Password Recovery Tool please visit http://www.biospasswordrecovery.com/ Hope it help to you.
"Installation of disk requires administrator privileges" error message?
+As with many software packages, it only allows the Administrator of the laptop to install the application. Subsequent use does NOT require that YOU BE the administrator; just for installation. Log onto your laptop as adminstrator or alternatively: Insert the CD into the drive and hold down the left SHIFT key so it does not autorun. When you are sure that the setup will not launch, EXPLORE the CD and find the the setup.exe file that launches the installation. Again, hold down the left SHIFT key and do a single right mouse click. When you see the short menu, release the SHIFT key. From the short menu, select the option to Run As and then select Administrator.
What would be the use of Kibana and Grafana softwares for an Administrator?
Our system administrators use Grafana paired up with Graylog, log management system. These two tools allow us to keep an eye on performance and technical state of the software we develop.Pure text logs or error notifications are not “interesting” to Grafana as its main purpose is to visualize the data in graphs, charts and tables. We wrote a custom module for Django to collect the data we’d like to track for every web/worker request and response processed, and these details are always available for the admin. So every time an error occurs, he could trace it up to the entire request/response and debug the app. For instance, if there are anomalies in response time:or in system load:You could find find more about system performance and load tracking with Grafana here: Grafana as a Yet Another Tool for Technical Monitoring of Software Products We BuildHere’s more about Grafana + Graylog combination: Graylog as a Tool for Technical Monitoring of Software Products We Build
