Site Configuration

Innovation and dedication have led Computer Research Center to the forefront in delivering a comprehensive package called “Computer System Profile.” This package is like a blue print of your entire computer network system. Package includes: Hardware and software information of all servers. Hardware and software information of all workstations. Graphical presentation of physical location of all hardware components . Network topology and wiring schematics. Network connectivity of servers, workstations, hubs, switches, routers, and printers. Internet schematic, e-mail distribution, an IP routing of the entire network. Users’ identifications and software. Advantages of having a “Computer System Profile” In case of problem with any component, a system engineer can work more efficiently and identify the problem quicker. You can use this profile for upgrading the systems. Provides a great asset management of your computer systems. It can be used for insurance claims in case of any disaster. Method of Implementation: At the client site(s), CRC will examine the entire network system and operation and collects the required data. These data are then entered into our software program to produce a comprehensive Computer System Profile.

Security

Firewalls or Application Gateways Application level firewalls or Application gateway Application gateways look at data at the application layer of the protocol stack and serve as proxies for outside users; they intercept packets and forward them to the application. Thus, outside users never have a direct connection to anything beyond the firewall or gateway. The fact that the firewall looks at this application information means that it can distinguish among such things as telnet, file transfer protocol (FTP), or Lotus Notes traffic. Because the application gateway understands these protocols, it provides security for each application it supports. Anti-virus, Anti-worm, and Anti-vandal Programs Collectively, these programs combat malicious programs known as viruses, worms, and vandals: Viruses invade computers and networks and wreak havoc on them. The mischief caused can be very minor, such as causing a funny image or cryptic message to be displayed on your screen, or it can do some serious damage by altering or even destroying files. Worms are a type of virus that disables computers by creating a large number of copies of itself within the computer's memory, forcing out other programs. Worm viruses are generally constructed to also copy themselves to other linked computers.

Wide Area Network

Frame Relay is the result of wide area networking requirements for speed; LAN-WAN and LAN-LAN internetworking; "bursty" data communications; multiplicity of protocols and protocol transparency. These requirements can be met with technology such as optical fiber lines, allowing higher speeds and fewer transmission errors; intelligent network end devices (personal computers, workstations, and servers); standardization and adaptation of ISDN protocols. Frame Relay could connect dedicated lines and X.25 to ATM, SMDS, BISDN, and other "fast packet" technologies.

Frame Relay uses the same basic data link layer framing and Frame Check Sequence so current X.25 hardware still works. It adds addressing (a 10-bit Data Link Connection Identifier (DLCI)) and a few control bits but does not include retransmissions, link establishment, windows or error recovery. It has none of X.25's session layer but adds some simple interface management. Any network layer protocol can be used over the data link layer Frames.

Local Area Network

CRC is a pioneer in configuring and installing Local Area Network (LAN.) We provide design, solution, migration, and installation of Microsoft and Novell Local Area Network A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link and typically share the resources of a single processor or server within a small geographic area (for example, within an office building). Usually, the server has applications and data storage that are shared in common by multiple computer users. A local area network may serve as few as two or three users (for example, in a home network) or many as thousands of users. Typically, a suite of application programs can be kept on the LAN server. Users who need an application frequently can download it once and then run it from their local hard disk. Users can order printing and other services as needed through applications run on the LAN server. A user can share files with others at the LAN server; read and write access is maintained by a LAN administrator. A LAN server may also be used as a Web server if safeguards are taken to secure internal applications and data from outside access. In some situations, a wireless LAN may be preferable to a wired LAN because it is cheaper to install and maintain.
