The facilities (laboratories, classrooms, teacher offices housed in the main building of the Department (building 5 on map) which was built with specifications suitable for Department of Computer Science and a smaller building, which houses the laboratory 301, the multi-purpose room (302 ), and the offices of two teachers, and Network Operations Center (Building 18 on map). The theoretical studies carried out on the ground floor in rooms 101, 102, 109 and in the auditorium of the Department. The laboratory lessons, held in rooms 201, 202, 208, 210 211 and 301. The Laboratory of digital circuits is conducted in room 3019 in the old building of STEF (building 2 on map). The room 209 on the first floor of the main building accommodates the servers and networking equipment . For a look at the backbone of the Board follow the direction http://hydra.it.teithe.gr/netmap The training Equipments organized into six labs and is a local area network served by the following servers:

• aetos: central server for all members of the department (students-teachers) who provide services WEB, MAIL, DNS, etc.
• vserver: server that supports a host computer using virtual technology vserver
• medusa: server which supports a number of virtual computers using XEN technology
• tux: central firewall
• hydra: server for student services and management needs of the whole department
• gypas: server support services ghost, anivirus etc.
• iPv6: act as IPv6 Router for the whole section
• vod: server service video-on-demand
• nas, titanas, gigas: file servers to provide storage and backup
• erodios: server support research programs

These servers serve more than 190 workstations are allocated to six laboratories and offices of teachers:

• Operating Systems (Room 201) with 24 stations
• Programming II Room 202) with 24 stations
• Multimedia (Room 208) with 24 stations
• Programming I (Room 211) with 24 stations
• Network and Computer Graphics (Room 210) with 24 stations
• Internet Applications (Room 301) with 26 stations
• Laboratory to support research programs (Room 302) 10 stations
• Offices teachers and technical staff of 26 stations

All these stations are a single network, which is built on the philosophy of all-in-one. Each of these parties have structured wiring and served as a high level of networking equipment (Cisco Switches 3550, 2950). H management and monitoring equipment is mostly from software developed by our department or free software. The backbone of the department is structured with multi-mode optical fiber (gigabit) In this section we installed a wireless network that covers two floors of the main building and small building opposite. In our department has installed a network VPN, that teachers and students have access to specialized services (eg subscriptions to scientific journals, scores, etc.). Students and department staff may have access to the network of the Department, either through private connections via ADSL or dial-up free access to 64 ISDN Modem (Regional Call Number 8962504440).
