Unit 2204 Stage 1 Network Security
BSC IN INFORMATION TECHNOLOGY â Stage II Semester 1
BIT 2204: NETWORK SYSTEMS ADMINISTRATION
COURSE OUTLINE
Purpose of the Course:
The course equips the student with the necessary skills in administer different network platforms in terns of network users and shared resources.
Expected Learning Outcomes:
Upon completion of the course, the student should be able to:
⢠Outline the roles, responsibilities and ethics in network administration.
⢠Install, configure, troubleshoot and mange different network operating systems.
⢠Configure DHCP, DNS and WINS on a Windows server.
⢠Create user accounts, and implement group policies in a network environment.
⢠Explain network security concepts

The core of a coaxial cable carries the electronic signals that make up the data. This wire core can be either solid or stranded. If the core is solid, it is usually copper. 2. a braided metal shielding, The braided wire mesh acts as a ground and protects the core from electrical noise and crosstalk. (Crosstalk is signal overflow from an adjacent wire. 3. An outer cover. A nonconducting outer shieldâusually made of rubber, Teflon, or plasticâsurrounds the entire cable. [pic] Coaxial cable showing various layers
Note:
Shielding protects transmitted data by absorbing stray electronic signals, called noise, so that they do not get onto the cable and distort the data.
Coaxial cable is more resistant to interference and attenuation than twisted-pair cabling. Attenuation is the loss of signal strength that begins to occur as the signal travels farther along a copper cable.

Types of Coaxial Cable
There are two types of coaxial cable: ⢠Thin (thinnet) cable ⢠Thick (thicknet) cable
Which type of coaxial cable you select depends on the needs of your particular
