A connection to a network (usually the Internet) provided by dialing a phone number with a modem and making an analog connection to another modem. This connection allows data to be transmitted between the two.
A type of networking architecture. It provides standards for the hardware that is necessary to connect multiple computing devices together. It uses either coaxial or twisted pair wiring to connect devices. It is typically used for LAN communications. It can operate at speeds of 10/100/1000 Mbps.
A piece of cabling that is capable of carrying Ethernet signals and is used to connect a network device (computers, printers, etc.) to the network.The cable connecting the device to the wall jack is called a patch cable.
Measures the number of clock cycles (changes in electric current) in millions per second. One GHz is equal to 1,000,000,000-clock cycles/second. This is one indicator of how fast a computer can process data. 1000 Mhz = 1 Ghz.
Internet Messaging Access Protocol (IMAP) is an email protocol. It provides access to your network mailbox while connected to the server. You can view messages, create folders or delete messages as if your email was on your local computer.
Local Area Network (LAN) is a group of computers physically connected, sharing resources in the same general vicinity. Manhattan Campus would be a large LAN, and the University Network would be considered a WAN (Wide Area Network) because of the different technologies used to connect computing resources and the geographic distance it covers.
A data storage area that resides on another computer but has been assigned a drive letter on your computer. This allows you to access remote storage as though it were a local drive. On our network, drives Y:, S: and W: are mapped network drives.
Megabyte is a unit used to measure data storage capacity. All data is stored in computers as bits (ones and zeros). There are 8 bits in a byte and approximately 1,000 bytes in a kilobyte (KB). There are about 1,000 KB in a megabyte. So, 1 MB is about 8,000,000 bits or 1,000,000 bytes.
Measures the number of clock cycles (changes in electric current) in millions per second. One MHz is equal to 1,000,000-clock cycles/second. This is one indicator of how fast a computer can process data.
Post Office Protocol 3 (POP3) is an email protocol. It provides one of the most popular ways to receive email; the server stores email until a client connects and requests their messages. The email is then stored on the local computer.
Random Access Memory (RAM) is the physical memory your computer uses to temporarily store data. In the multi-processing computer environment its importance has increased in determining overall speed of a computer. RAM is commonly measured in MB.
A computer that delivers services to clients. There can be many different types of servers depending on what services (email, web, ftp, file services) they offer. A server is often a specialized computer designed for performance, dependability, and fault-tolerance.
