The Virtual Library was the first index of content on the World Wide Web and still operates as a directory of e-texts and information sources on the web. It was started by Tim Berners-Lee, the creator of HTML and the Web itself, in 1991 at CERN in Geneva. Unlike commercial index sites, it is run by a loose confederation of volunteers, who compile pages of key links for particular areas in which they are expert. It is sometimes informally referred to as the "WWWVL", the "Virtual Library" or just "the VL".
Information resources or information services that are available over the Internet. At BMCC, the Virtual Library site provides access to a large number of library resources (indexes, journals, and reference materials, for example) and online reference service via the campus computer network. Students access these resources through a browser on a workstation anywhere on campus or remotely from home. A search aid that combines Internet technology with traditional library methods of cataloguing and assessing data.
The individual indices, or virtual libraries live on hundreds of different servers around the world. A set of index pages linking these individual libraries is maintained at http://vlib.org/, in Geneva only a few kilometres from where the VL began life. A mirror of this index is kept at East Anglia (UK). A VL specific search engine has operated for some years and is now (VLsearch) located on its own server at vlsearch.org.
The central affairs of the Virtual Library are co-ordinated by an elected Council. A central index (the 'Catalog') is maintained and joint services provided by the Council on behalf of the association.
My Role in virtual library is Systems Administrator. A system administrator, systems administrator, or sysadmin, is a person employed to maintain and operate a computer system and/or network. System administrators may be members of an information technology department. The duties of a system administrator are wide-ranging, and vary widely from one organization to another. Sysadmins are usually charged with installing, supporting, and maintaining servers or other computer systems, and planning for and responding to service outages and other problems. Other duties may include scripting or light programming, project management for systems-related projects, supervising or training computer operators, and being the consultant for computer problems beyond the knowledge of technical support staff. A System Administrator must demonstrate a blend of technical skills and responsibility.
The challenges facing me in performing the role of systems administrator are:
1. Operating Systems and Applications Challenge – I can address this challenge by maintaining a database system, and handling the responsibility for the integrity of the data and the efficiency and performance of the system. I will make sure that the network infrastructure such as switches and routers, and diagnoses problems with these or with the behavior of network-attached computers. I can confront this challenge by analyzing system logs and identifying potential issues with computer systems, introducing and integrating new technologies into existing data center environments, and performing routine audits of systems and software and backups. I can also meet this challenge by applying operating system updates, patches, and configuration changes and performing system performance tuning
2. Problem Solving and Troubleshooting Challenge- I can address this challenge by responding to individual users' difficulties with computer systems, provide instructions and sometimes training, and diagnose and solve common problems. I will perform routine maintenance and upkeep, such as changing backup tapes or replacing failed drives in a RAID. Such tasks usually require physical presence in the room with the computer; and while less skilled than sysadmin tasks require a similar level of trust, since the operator has access to possibly sensitive data. I am also ready and to be on the call when a computer system goes down or malfunctions, and must be able to quickly and correctly diagnose what is wrong and how best to fix it.
3. Software Engineering or Developing Challenge– I will face this challenge by maintaining web server services (such as Apache or IIS) that allow for internal or external access to web sites. Tasks include managing multiple sites, administering security, and configuring necessary components and software. Responsibilities may also include software change management. I must understand the behavior of software in order to deploy it and to troubleshoot problems, and generally know several programming languages used for scripting or automation of routine tasks.
4. Computer Security Challenge– I will dare this challenge by engaging into a study and training to make a specialist in computer and network security, including the administration of security devices such as firewalls, as well as consulting on general security measures. Particularly when dealing with Internet-facing or business-critical systems, I must challenge myself to have a strong grasp of computer security. This includes not merely deploying software patches, but also preventing break-ins and other security problems with preventive measures. Computer security administration is also my role that is responsible for overall security and the upkeep of firewalls and intrusion detection systems, but all I must be generally responsible for the security of the systems in their keep.
