Straight Cable - Answer-Used to connect devices of the same type, such as a
computer to a switch or a router to a modem. This type of cable is wired in such a
way that both ends are identical, making it simple to plug in.
When connecting to a PC it uses an intermediate device (Switch or router)
Crossover Cable - Answer-Used to connect two devices directly to each other
without the need for a switch or router. The wiring of the cable is designed in such a
way that the transmit and receive signals are crossed over, allowing data to be
transmitted directly from one device to the other. This type of cable is commonly
used for network testing or to transfer files between two computers.
When connecting to a PC it uses direct communication
Roll Over Cable - Answer-Also known as a console cable, is used to connect a
computer to a networking device's console port for out-of-band management. This
type of cable has a DB-9 or RJ-45 connector on one end and a serial connector on
the other.
Cables and Termination of wires - Answer-Cables:
Different types of cables have different capabilities, such as the maximum
transmission distance, speed, and resistance to noise and interference.
The choice of cable can also affect the performance of a network, such as the overall
speed and reliability of the connection.
Termination of wires:
Proper termination of wires is essential to ensure a secure and stable connection.
If wires are not properly terminated, it can cause problems such as loose
connections, crosstalk, and signal loss.
Poor termination can also result in increased resistance, which can cause a
reduction in signal quality and overall performance.
Issues related to cables and termination - Answer-Damaged or frayed cables, which
can cause signal loss and connectivity problems.
Loose or poorly terminated wires, which can cause a loss of signal quality and
network performance.
Improper cable length, which can result in signal degradation or loss.
Use of incorrect cables, such as using a straight-through cable instead of a
crossover cable.
To avoid these issues, it is important to choose the appropriate type of cable for your
network, ensure proper wire termination techniques, and regularly check for signs of
damage or wear.
