Computer Networking

A shielded twisted pair or STP is a copper telephone cable that secures signal-carrying wires inside a conducting shield. It main purpose is to reduce the possibility of electromagnetic intrusion.

In a star topology, each device connects to a central network connectivity device such as a hub, switch, or router. These devices would be connected as a "star" (points on a star).

The other characteristic of a star topology is that a failing connection will only affect the failed device unless that device is the connectivity device. This means that in most cases a failing device on a star will not take down the entire network.

Another characteristic of a star is that they are easily expandable and scalable.

The maximum distance an IrDA device can trasmit is 1 meter. The effective range between two IrDA devices is 2 meters.

The top most layer is the application layer and bottom most layer is the physical layer. Since data is transferred from top to bottom, I would say that the starting layer is the application layer.

The OSI Model is involved in networking, and consists of 8 layers. Without going into much detail, the layers from top to bottom are...

If you need to know more, the course CCNA 1 in cisco networking is based on this model amongst other things, as well as the TCP/IP model, which is a simpler version of OSI.

Adobe Illustrator is a vector-based (meaning it doesn't pixellate even if you zoom in) drawing program which was developed and marketed by Adobe Systems.

Light, typically IR.

Transport Layer

This is not correct, it's the session layer of the OSI model

SSL was created with the TCP/IP model in mind, not the OSI model. While it is technically true SSL or TLS is in the Session Layer of the OSI, it should be referred to in conjunction with the TCP/IP Model. In this case, it resides above the Transport Layer, providing security for it, hence the name of SSL's successor Transport Layer Security (TLS).

Note: TLS 1.0 is SSL 3.1

FYI, please take note the ITU X.800 recommendation states there are no security services provided in the session layer.

The recovery method that typically involves an evasion effort and is dependent on an individual's condition is known as "cognitive behavioral therapy" (CBT). This approach focuses on helping individuals identify and change negative thought patterns and behaviors, often requiring them to navigate and evade harmful impulses or triggers in their environment. The success of CBT can vary based on the individual's mental and emotional state, making it crucial to tailor the therapy to their specific needs.

Protocols that describe methods for exchanging data frames between devices over a common medium include Ethernet and Wi-Fi (IEEE 802.11). Ethernet uses a frame structure to encapsulate data and employs CSMA/CD (Carrier Sense Multiple Access with Collision Detection) for managing access to the network. Wi-Fi, on the other hand, utilizes CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) to handle access in wireless networks. Both protocols ensure that devices can effectively communicate and share the medium without data loss.

In general, the MAC address is tied to a specific piece of hardware and does not change. It is possible, however, under certain circumstances to change the MAC address.

MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address.

Although intended to be a permanent and globally unique identification, it is possible to change the MAC address on most modern hardware. Changing MAC addresses is necessary in network virtualization. In this case, the MAC address of the actual NIC is hidden from the network and the network only sees the MAC assigned to the virtual NIC - which can be configured, with some finesse, to be dynamic. It can also be used in the process of exploiting security vulnerabilities. This is called MAC spoofing.

RJ45 Modular connector can be bought at many different electronic stores in the neighborhood such as Radio Shack or Best Buy. Purchasing online can save you some money so be sure to check out ebay or amazon online stores.

That would be a class E network, E networks do not have defines subnet masks or networks. Just a range (240.0.0.0 - 255.255.255.255).

Although 10GBASE-T transmits & receives data on the same wires, it, like 1000BASE-T before it, implements echo cancellation so that the transmit & receives signals can occupy the cable at the same time without interference. This allows full duplex communication (i.e., transmit and receive at the same time) without collision.

A graded index multimode fiber will transmit 800 modes, and has a varying refractive index. A step index multimode will transmit 228 modes.

LAN stands for Local Area Network. It like an office with all the computers hooked so they can share data and send emails just inside the office or building. A WAN stands for Wide Area Network and it connects two or more LANs...the Internet is a good of example of a WAN...the internet consists of a network connected to other networks..hope this helps.

Generally, you are referring to the class of Filesystems known as Cryptographic file systems. A crypto filesystem uses a symmetric algorithm to encode the contents of disk; it requires a special key to be able to use.

Several common filesystems now support a Cryptographic mode.
