Frame relay
Frame relay is method of network transmission whereby the frame is designed to operate in virtually error-less circuits. This protocol is stripped down to enhance transmission speed. The method operates in a manner that network layer of the OSI model is created and the routing process and multiplexing roles is performed by itself and hands over everything else to the levels higher in the network transmission hierarchy.
Frame relay omits the former roles such as sequential ordering, window rotation, acknowledgement of frames, and automated retransmission in case of failure so as to focus on the fundamental roles which is fast transmission of packed data frames in proper sequential order as well as directing it to the desired place.
Frame relay functions in an efficient manner by doing combination of roles of Data link layer and the Network layer to form a single and simple communication protocol. Frame delay performs the role of Data Link layer by delimiting and delivery of properly ordered, and checks from errors by using the CRC. In addition it performs the role of Network Layer protocol by offering several logical linkages over one physical circuit and permits routing of data to desired places.
ISDN
ISDN in full stands for Integrated Services Digital Networks. It refers to a package of international standards providing access of sophisticated combination of digital telecommunications networks. ISDN integrates video, image, data, voice, and mixture of media data based on several standards of data rates. Services in the ISDN are fully digitally transmitted. ISDN defines a network and not a combination of standards of private-line services. ISDN provides for one fabric of transmission and switching services operating on standards of common interest, distributed control and national telecommunication bodies. The main elements if ISDN include access types, ISDN channels, interfaces, protocols and ISDN devices. In simple terms, ISDN refers to integration of analog with digital so as to be transmitted over the same network.
Cable modem
Cable modem is an external device that helps one connect to the internet. It has two connection points whereby one end is connected to TV cable and the other end connected to a personal computer. It allows data rate of about 1.5Mbps. This rate if by far higher than that of telephone modems. Cable modem may be integrated with a set-top box so as to allow internet access channels on the TV.

Recommendations for Star Clothing Organization
Use of RFID
Radio Frequency Identification is a technology whereby objects are uniquely identified using incorporation of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum (Glover, & Bhatt, 2006). This is a useful technology that the Star Clothing should consider implementing to track the stocks. Every piece of cloth should be tagged using a transponder so that when an action is taken the transponder gets activated following whatever activity being carried out against the cloth. The same should be interfaced with the database so as monetary transactions could be executed against it.
Handheld scanners
Use of handheld scanners will help the organization speed up the transaction processes. The devices are known to be efficient in their operation. It helps in the control process of the inventories.
Portable cell phones
The company should consider use of cell phone to enhance communication among the company personnel as opposed to the traditional form of office telephones whereby communication can only be made if you are in office. This will enhance the speed of business operations and real time communication among different departments and sections of the organization. This also creates an efficient linkage between the main store and the regional stores.
