Information Management Center, CGI
Information Management Center is short for CGI according to abbreviationfinder. Scientific and technological information center, in addition to the university library, of the University of Camagüey “Ignacio Agramonte Loynaz”, UC. Founded in 1977, in September 2014 it became part of the Directorate of Scientific Information Management, DGIC, together with the libraries of two other Camagüey universities, in the new UC. Since 2017 it has been renamed as the Directorate of Technical Scientific Information.
Officially considered the date of creation of the CGI, the 25 of April of 1977 when they opened the current premises of the then named Center of Scientific – Technical, IFTC, of the University of Camagüey. The name of the University Library, Felipe Torres Trujillo, is that of a distinguished Cuban revolutionary.
Throughout its history, the CGI has made extraordinary strides, always being among the leading institutions of its kind. Thus, the 90s witnessed the introduction of modern technologies in our management, the reorganization of our services, thanks to the implementation of process reengineering throughout the center’s work system and the implementation of the processes most modern information management.
In 1997, the center changed its name to the Information Management Center, much closer to what has been proposed since then as an organization. More than a traditional library, an organization that manages the internal and external scientific and technical information of the University of Camagüey, and turned them into high-value information products for its users or clients.
The Information Chair
An important fact of that stage was the creation of the Information Chair in 1995. Created by Dr. in Sciences Fidel García González and Ms. Sara Artiles Visbal, the chair promoted the introduction of the teaching of the then New Information and Communication Technologies (NTIC), in the undergraduate and graduate programs of the University of Camagüey, being one of the first experiences of this type in our country. The chair was the precedent for the subsequent creation of the Department of Information Sciences and the current Bachelor’s degree in Information Sciences at UC.
UC’s first multimedia products were also the result of the experience and work of the Information Chair and its members.
Extinct, it became part of the Directorate for Scientific Information Management, DGIC, created in September 2014 when several Camagüey universities joined.
Accelerated Graphics Port (AGP)
Accelerated Graphics Port (AGP), known as the accelerated graphics port , is called a port, since only one device can be connected, developed by Intel Corporation in 1996, with the aim of solving the low performance that originated in the card. graphics that used the PCI bus, its design part of the PCI 2.1 specifications.
The AGP port is 32 bit like the PCI, but it has considerable differences such as 8 more additional channels of access to the RAM memory. In addition to directly accessing it through the north bridge, thus managing to emulate the video memory in RAM. The bus speed is 66 MHz.
The AGP bus has different modes of operation.
- AGP 1X: 66 MHz speed has a transfer rate of 266 MB / s and operates at a voltage of 3.3V.
- AGP 2X: 133 MHz speed has a transfer rate of 532 MB / s and operates at a voltage of 3.3V.
- AGP 4X: 266 MHz speed has a transfer rate of 1 GB / s and operates at a voltage of 3.3 or 1.5V to suit graphics card designs.
- AGP 8X: 533 MHz speed has a transfer rate of 2 GB / s and operates at a voltage of 0.7V or 1.5V.
These transfer rates are achieved by taking advantage of the bus clock cycles by means of a multiplier but without physically modifying them. The AGP port is used only for the connection of graphics cards, and due to its architecture there can only be one slot, which measures about 8 cm and is located to one side of the PCI slots.
As of 2006, with the appearance of PCI-Express, which provides greater benefits in terms of frequency and bandwidth, and due to the fact that the main graphic card manufacturers, such as ATI and NVIDIA, have been manufacturing less and less products for this port the use of the AGP port has been decreasing.
