Know the names of various WAN technologies
· modems
· ISDN (Integrated Services Digital Network)
· DSL (Digital Subscriber Line)
· Frame relay
· ATM (Asynchronous Transfer Mode)
· The T (US) and E (Europe) Carrier Series: T1, E1, T3, E3, etc.
· SONET (Synchronous Optical Network)
a printed circuit board that provides network communication capabilities to and from a personal computer
When you select a network card, consider the following three factors:
1. type of network (for example, Ethernet, Token Ring, or FDDI)
2. type of media (for example, twisted-pair, coaxial, or fiber-optic cable)
3. type of system bus (for example, PCI or ISA)
Some of the factors that determine throughput and bandwidth include the following:
· internetworking devices
· type of data being transferred
· topology
· number of users
· user's computer
· server computer
· power and weather-induced outages
Convert the decimal number 192 to a binary number.
192/2 = 96 with a remainder of 0
96/2 = 48 with a remainder of 0
48/2 = 24 with a remainder of 0
24/2 = 12 with a remainder of 0
12/2 = 6 with a remainder of 0
6/2 = 3 with a remainder of 0
3/2 = 1 with a remainder of 1
1/2 = 0 with a remainder of 1
Write down all the remainders, backwards, and you have the binary number 11000000.
