In computer it's known as com port and could be available in 9pin or 25 pin.On router it have 60 pins.
What's the benefit of subnetting?
Reduce the size of the routing tables.
Reduce network traffic. Broadcast traffic can be isolated within a single logical network.
Provide a way to secure network traffic by isolating it from the rest of the network.
What are the differences between static ip addressing and dynamic ip addressing?
With static IP addressing, a computer (or other device) is configured to always use the same IP address. With dynamic addressing, the IP address can change periodically and is managed by a centralized network service
What is APIPA?
Automatic private IP addressing (APIPA) is a feature mainly found in Microsoft operating systems. APIPA enables clients to still communicate with other computers on the same network segment until an IP address can be obtained from a DHCP server, allowing the machine to fully participate on the network. The range of these IP address are the 169.254.0.1 to 169.254.255.254 with a default Class B subnet mask of 255.255.0.0
What is DHCP scope?
A scope is a range, or pool, of IP addresses that can be leased to DHCP clients on a given subnet.
What are the criteria necessary for an effective and efficient network?
Performance : It can be measured in many ways, including transmit time and response time.
Reliability : It is measured by frequency of failure, the time it takes a link to recover from a failure, and the network's robustness.
Security : Security issues includes protecting data from unauthorized access and viruses.
Name the factors that affect the performance of the network?
Number of Users
Type of transmission medium
Hardware
Software
Name the factors that affect the reliability of the network?
Frequency of failure
Recovery time of a network after a failure
What is Protocol?
A protocol is a set of rules that govern all aspects of information communication.
Define Bandwidth and Latency?
Network performance is measured in Bandwidth (throughput) and Latency (Delay). Bandwidth of a network is given by the number of bits that can be transmitted over the network in a certain period of time.
Latency corresponds to how long it takes a message to travel from one end off a network to the
other. It is strictly measured in terms of time.
