DEFINITION of initial program load
IPL (initial program load) is a mainframe term for the loading of the operating system into the computer’s main memory . A mainframe operating system (such as OS/390) contains many megabytes of code that is customized by each installation, requiring some time to load the code into the memory. On a personal computer, booting or re-booting (re-starting) is the equivalent to IPLing (the term is also used as a verb) .
DEFINITION of mesh network
A mesh network is a local area network (LAN) that employs one of two connection arrangements, full mesh topology or partial mesh topology. In the full mesh topology, each node (workstation or other device) is connected directly to each of the others.

DEFINITION of microchip
A microchip (sometimes just called a “chip”) is a unit of packaged computer circuitry (usually called an integrated circuit) that is manufactured from a material such as silicon at a very small scale. Microchips are made for program logic (logic or microprocessor chips) and for computer memory (memory or RAM chips).
DEFINITION of Point-to-Point Tunneling Protocol
Point-to-Point Tunneling Protocol (PPTP) is a protocol (set of communication rules) that allows corporations to extend their own corporate network through private “tunnels” over the public Internet. Effectively, a corporation uses a wide-area network as a single large local area network. A company no longer needs to lease its
