7. What are three things to consider when choosing an Ethernet cord?
1. Speed capabilities: Consider the maximum data transfer speed that the Ethernet cord can handle, such as Cat 5e cables can support up to 1 Gbps, while Cat 6 cables can support up to 10 Gbps.
2. Cable length: Consider the distance over which you need to run the Ethernet cord, as certain cables may have limitations on the maximum length they can effectively transmit data without signal loss or degradation.
3. Cable shielding: Consider the level of interference protection provided by the Ethernet cord. Shielded cables (STP) can provide better protection against external electromagnetic interference, while unshielded cables (UTP) are more susceptible to signal interference. The choice depends on the specific environment where the cable will be used.
Research: Some of theses cables are available in UTP and STP. Using your
resources, determine what these acronyms stand for. Which do you think is
the better cable?
UTP stands for Unshielded Twisted Pair, which is a type of Ethernet cable that does not have any additional shielding or grounding. It uses twisted pairs of wires to transmit data. UTP cables are more affordable and commonly used for everyday residential and small-scale commercial Ethernet connections.
STP stands for Shielded Twisted Pair, which is a type of Ethernet cable that has an additional layer of shielding to protect against electromagnetic interference. The shielding is usually made of metal foil or braided metal. STP cables are typically used in environments with high levels of electromagnetic interference, such as industrial settings or areas with a lot of electrical equipment.
The choice between UTP and STP cables depends on the specific requirements of the network environment. If there are no significant sources of electromagnetic interference, UTP cables are generally sufficient and more cost-effective. However, in environments where interference is a concern, or for longer cable runs, STP cables may be a better choice for ensuring reliable data transmission.
determine which is faster between GB and MB.
How much faster?
GB (Gigabyte) is faster than MB (Megabyte). The speed difference between GB and MB is significant.
1 GB is equal to 1024 MB. Therefore, when comparing the speed of data transfer or storage, 1 Gigabyte is approximately 1024 times faster than 1 Megabyte.
For example, if a transfer rate is given in terms of megabytes per second (MB/s), and if it was mentioned that the transfer speed is 100 MB/s, then the equivalent speed in gigabytes per second (GB/s) would be 0.0977 GB/s.
In summary, GB is much faster than MB, with a speed difference of approximately 1024 times.
Jamal's computer is able to connect to the Wi-Fi signal, but there is no
Internet access. Which device do you think might be causing the problem and why?
The problem could be caused by multiple devices, but a common culprit in this scenario could be the router. Here's why:
1. Router configuration: If the router is not properly configured, it may not be providing an internet connection despite the Wi-Fi signal being accessible. This could be due to settings such as incorrect DNS configuration or IP address conflicts.
2. Network connectivity: The router might not have a stable or active internet connection from the service provider. This could be a result of issues such as a faulty modem, poor signal strength from the ISP, or an outage in the area.
3. Router firmware or hardware issues: Outdated firmware in the router or hardware problems could also lead to connectivity issues. It's possible that a firmware update is required or the router itself may need to be replaced.
It's worth noting that other devices such as the modem, network cables, or the computer itself could also be causing the issue. Further troubleshooting and investigation would be necessary to pinpoint the exact cause.
Felicia's Wi-Fi connection to her phone is extremely slow. However, her
computer that is wired directly to the modem works really well. Which device
do you think might be causing the problem and why?
In this scenario, the problem is likely with Felicia's phone or the Wi-Fi connection itself. Here's why:
1. Phone settings or software issues: The slow Wi-Fi connection could be a result of misconfigured settings on the phone or software issues. For example, the phone might be prioritizing a weak Wi-Fi signal over cellular data, leading to a slow connection. Updating the phone's software or adjusting the Wi-Fi settings may resolve the issue.
2. Wi-Fi interference: The phone might be experiencing significant interference from nearby devices or networks, causing a slow connection. Other wireless devices, physical obstacles, or crowded Wi-Fi channels can all contribute to interference. Moving closer to the router or changing to a less congested Wi-Fi channel can help improve the connection speed.
3. Phone's Wi-Fi hardware or antenna: There could be a hardware issue with the phone's Wi-Fi antenna or the Wi-Fi chipset inside the phone. If the hardware is faulty, it may result in a slow or unstable connection.
Since the computer that is directly wired to the modem works well, it suggests that the issue lies specifically with the phone's Wi-Fi connection. Troubleshooting the phone's settings, checking for interference, and considering hardware issues can help identify and resolve the problem.

What is an open network? How about a secured network?
An open network refers to a wireless network (Wi-Fi) that does not have any security measures in place. It allows any device within range to connect to the network without requiring a password or any other form of authentication. Open networks are typically used in public places like cafes, airports, or libraries, where convenience and easy access are prioritized over security. However, open networks can pose risks as they are more susceptible to unauthorized access, data interception, and other security threats.
On the other hand, a secured network, also known as a protected network, is a wireless network that has security measures implemented to restrict unauthorized access. Secured networks use various security protocols such as WPA (Wi-Fi Protected Access) or WPA2 to encrypt the communication between devices and require a password or other forms of credentials for authentication. By using encryption and authentication mechanisms, secured networks help prevent unauthorized users from accessing the network, maintaining the privacy and integrity of the data transmitted over the network.
what are the fire wall rules
Firewall rules are policies that dictate how incoming and outgoing network traffic is allowed or blocked by a firewall. These rules are defined based on criteria such as source and destination IP addresses, ports, protocols, and other factors. The specific rules implemented can vary depending on the firewall software or hardware being used, but here are some common types of firewall rules:
1. Allow rules: These rules permit specific types of traffic to pass through the firewall. For example, an allow rule may be set to allow incoming HTTP traffic on port 80, or outgoing SMTP traffic on port 25.
2. Deny rules: These rules block specific types of traffic from passing through the firewall. For instance, a deny rule might be configured to block all incoming traffic on port 22 (SSH).
3. Port-based rules: These rules are based on specific ports and protocols. They determine whether traffic is allowed or blocked based on the source or destination port number and the protocol being used, such as TCP or UDP.
4. Source/destination IP-based rules: These rules control traffic based on the source and/or destination IP address. For example, a rule might be set to only allow traffic from a specific IP range or block traffic to a particular IP address.
5. Application-specific rules: Some firewalls have the capability to create rules specific to certain applications or services. These rules can define how the firewall handles traffic related to specific applications, ensuring secure and controlled access.
Firewall rules are typically set up by network administrators to enforce security policies, protect networks from unauthorized access, and manage network traffic effectively. The specific rules implemented will depend on the organization's security requirements and the objectives of the firewall deployment.

3. Only allow connections to Sales network that originate from the Internal network.
4. Only allow connections from the Sales network into the Internal network
and to the cloud backup server.
5. Block all other traffic.
1. Block any traffic heading for Snapgram from either the Internal or Sales networks:
- Source: Internal network, Sales network
- Destination: Snapgram
- Action: Block
2. Block any traffic heading into either network from any IP address starting with 43.11.x.x:
- Source: 43.11.x.x
- Destination: Internal network, Sales network
- Action: Block
3. Only allow connections to Sales network that originate from the Internal network:
- Source: Internal network
- Destination: Sales network
- Action: Allow
4. Only allow connections from the Sales network into the Internal network and to the cloud backup server:
- Source: Sales network
- Destination: Internal network, Cloud backup server
- Action: Allow
5. Block all other traffic:
- Action: Block (default outgoing and incoming traffic not explicitly allowed)
These are general examples of how the firewall rules could be specified based on the given requirements. Specific configurations may vary depending on the firewall platform or software being used.
Question: 5
What is a server OS used for?
Handling requests and supplying responses.
Running multiple operating systems on a computer system.
Performing one task, such as in an STM machine.
Running a permanent system, like the timing controls in a washing machine.
A server OS is used for handling requests and supplying responses.
Server operating systems are specifically designed to manage and control network resources and services in order to handle requests from clients and provide the necessary responses. These operating systems are optimized for performance, security, and reliability to ensure smooth operation and efficient delivery of services in a network environment.
Server OSs typically have features and functionalities that support tasks such as file sharing, serving web pages, hosting applications, managing user access, and facilitating communication between different components of a network. They are responsible for coordinating and managing the resources of the server, including hardware, software, and network connections, to fulfill client requests and deliver the requested services or data.
Unlike a general-purpose operating system used on individual computers, a server OS is designed to handle the unique demands of managing and serving multiple users, applications, and services in a networked environment.
What are three responsibilities of an operating system?
Three responsibilities of an operating system are:
1. Process and resource management: The operating system is responsible for managing processes, which are running instances of programs, and allocating system resources such as CPU time, memory, and input/output devices efficiently. It ensures that each process gets a fair share of resources and handles multitasking, scheduling, and synchronization between processes.
2. File system and data management: The operating system provides file system management, which includes organizing and storing files on disk, managing directories, and controlling access to files by different users. It handles tasks such as file creation, deletion, searching, and providing a hierarchical structure for file organization. The OS also takes care of data security and permissions, ensuring that authorized users have appropriate access levels to files and data.
3. User interface and hardware interaction: The operating system provides a user interface that allows users to interact with the computer system. This can be through a command-line interface (CLI) or a graphical user interface (GUI). The OS manages input and output devices, such as keyboards, mice, displays, printers, and network connections, facilitating communication between users and the hardware. It also handles device drivers and protocols necessary for hardware and software interaction.
These are just a few examples of the many responsibilities of an operating system. Its primary role is to provide an abstraction layer between hardware and software, managing system resources, enabling software execution, and facilitating user interaction with the computer system.
Better security is the top reason to keep your operating system updated and upgraded. Why do you think this is? Why would the newer versions of the OS have increased security?
Updating and upgrading your operating system is crucial for better security due to the following reasons:
1. Security patches and bug fixes: Newer versions of operating systems often include security patches and bug fixes that address vulnerabilities and loopholes discovered in older versions. Software vulnerabilities can be exploited by attackers to gain unauthorized access or compromise system integrity. By keeping your operating system up to date, you ensure that these vulnerabilities are patched, reducing the risk of security breaches.
2. Improved security features: Operating system upgrades often introduce enhanced security features and configurations. Newer versions may have stronger built-in firewalls, improved encryption algorithms, enhanced access controls, and more robust security frameworks. These additional security measures are designed to counter evolving threats and protect against modern attack techniques.
3. Response to emerging threats: Operating system developers continuously monitor and respond to emerging threats and security risks. They actively research and analyze attack patterns, vulnerabilities in existing software, and techniques used by cybercriminals. By upgrading your OS, you benefit from the security measures and enhancements that have been implemented to counter the latest threats.
4. End-of-life support: Operating system vendors provide updates and security patches for a specific period of time after release. Once an operating system version reaches its end-of-life (EOL) or is no longer supported, vendors may stop releasing security updates. This leaves your system vulnerable to newly discovered exploits. Upgrading to a newer version ensures that you continue to receive regular security updates and protection.
Overall, newer versions of operating systems have increased security because they address known vulnerabilities, introduce improved security features, respond to emerging threats, and provide ongoing support. Keeping your operating system updated and upgraded is essential for maintaining a secure computing environment.
