Installing a NIC • To install a NIC into a standard expansion slot on a desktop computer: 1. Power off the computer. 2. Open the computer case. 3. Locate a free slot. 4. Remove the slot cover. 5. Insert the card into the slot. 6. Secure the card in the slot. 7. Close the computer case.
NIC Installation • Add new Hardware Wizard • Add new hardware device
NIC Installation [cont.] • Pick installation way
NIC Installation [cont.] • Pick Network Adapter, then have disk
Network Interface Adapter Requirements • Network interface adapters use the following hardware resources: • An interrupt request (IRQ) • An input/output (I/O) port address • A memory address • A direct memory access (DMA) channel • Most network interface adapters require only an IRQ and an I/0 port address.
Understanding Ethernet Hubs • A hub connects all of the computers on a star or ring network. • Ethernet hubs are available in various sizes. • A hub creates a shared network medium on a LAN.
Objectives • What are protocols • Hardware Protocols • Software Protocol
What are Protocols • Hardware Protocol • How hardware device works • Voltage Levels • Which pairs of wire will be used • Software Protocol • Common language between clients & Servers • Like TCP/IP
Protocols Overview • IBM System Network Architecture • SNA (Small Network Addressee) • Novell Netware System • IPX/SPX (sequence protocol exchange) • Macintosh • Apple Talk • Internet Protocol • TCP/IP • Microsoft • NetBIOS/NetBEUI • NWLink
NetBIOS/NetBEUI • Developed by Microsoft • Small networks • Not routable • Not too much supporting tools • Broadcasting based
IPX/SXP • Developed by Novell • Routable • NetWare only • IPX handles the network layer
TCP/IP • Routing Protocol • Runs the Internet (support huge networks) • Many protocols (not just TCP and IP) • IP handles the network layer
Novell NetWare • First commercially successful network operating system • Pure client/server operating system
Protocol Rules • Two systems must have the same protocol to communicate • A single system can use more than protocol • Doesn’t have to have two NICs
IP Functions • Encapsulation (consist both of heasder&&data) • Addressing • Routing • Fragmentation(the role of router because when the (MTU)of packet increase about that size it must be fragment and each fragment has (h&d). • Protocol identification
Configure Network • Install Protocol • Install Client software • Install Service Software
Transmission Transmission type Transmission mode Transmission media
Transmission type • Broadcast • Unicasting • Multi Cast
Transmission type Unicasting ( إرسال البيانات إلى واحدة ضمن الشبكة دون غيرها ( T_ Type Broadcasting ( إرسال البيانات إلى جميع الجهات في الشبكة( Multi casting (إرسال البيانات إلى أكثرمن جهة لكن ليس للكل)
2.Transmission Mode T_ Mode Simplex (تمكن من استقبال المعلومات دون القدرة على الإرسال ) زى رجل الشرطه بالحكومه المصريه Half Duplex تمكن من تبادل الإرسال لكن ليس في نفس الوقت )) Full Duplex تمكن من تبادل الإرسال وفي نفس الوقت) )
