It is false that the first-fit memory allocation algorithm is slower than the best-fit algorithm (on average).
The operating system must maintain a list of each memory location, noting which ones are free and which ones are busy, for both fixed and dynamic memory allocation schemes. The available partitions must then be assigned as new workloads are added to the system.
Allocating Memory First-Fit:
The free/busy list of tasks is maintained using this strategy, which maintains low-ordered to high-ordered memory organization. This method assigns the first work the first memory space that is greater than or equal to its size. Instead of looking for a suitable partition, the operating system simply assigns the task to the closest memory partition that is large enough.

which extended acl port number parameter indicates a direct match for a specific application/application number?
The port number parameter in an extended access control list (ACL) can be used to specify a specific application or application number that should be directly matched by the ACL.
For example, if you wanted to allow or deny access to a specific application that uses a particular port number, you could use the port number parameter in the ACL to specify that port number.
What is the Port number parameter?
Overall, the port number parameter in an extended ACL allows you to specify a specific application or application number that should be matched by the ACL, allowing you to more precisely control access to specific applications or services on your network.

The recursive relation I came up with is
E(10)=1/2E(9)+1/4E(8)+1/4(E(9)+1)
The last toss has a probability of 1/2, so we only need to look at the number of consecutive heads in the first nine tosses. However, if the last toss is H, it matters what the second last toss was; if it was TH, then the number of consecutive heads was the same as in the first eight tosses; however, if it was HH, then the number of consecutive heads was one more than the number of heads in the first nine tosses.
The solution given states the following recursive relation

a network administrator configures the port security feature on a switch. the security policy specifies that each access port should allow up to two mac addresses. when the maximum number of mac addresses is reached, a frame with the unknown source mac address is dropped and a notification is sent to the syslog server. which security violation mode should be configured for each access port?
warning
protect
shutdown
restrict
Answer:
protect
Explanation:
When the "protect" mode is configured, the port security feature on the switch will drop any frames with unknown source MAC addresses and send a notification to the syslog server when the maximum number of allowed MAC addresses is reached. This allows the network administrator to be notified of potential security violations, while still allowing the port to continue functioning and forwarding frames.
The other security violation modes have different behavior:
"warning" mode sends a notification to the syslog server but does not drop frames with unknown source MAC addresses."shutdown" mode disables the port when the maximum number of allowed MAC addresses is reached."restrict" mode drops all frames with unknown source MAC addresses, but does not send a notification to the syslog server.a remote access policy tends to cover every remote access option. what are some common remote access methods?

the global system for mobile communications (gsm) utilizes what technology to create timeslots on a channel?
Time division multiple access (TDMA) technology is used by the global system for mobile communications (gsm) to establish timeslots on a channel.
The channel access technique known as time-division multiple access (TDMA) is utilized for shared-medium networks. It makes it possible for several users to share a single frequency channel by splitting the signal up into several time slots. Each user utilizes a different time slot and transmits one after the other quickly. This allows a lot of stations to use the same transmission medium by using only a portion of the channel's capacity (such as a radio frequency channel). The TDMA variant known as dynamic TDMA dynamically reserves a variable number of time slots in each frame to variable bit-rate data streams based on the traffic requirements of each data stream.
