CABLE SPECIFICATION

The Sonic Computer Shop uses UTP (Unshielded Twisted Pair) Cable Category 5 with a race of 100 mbps that uses 100BaseT Ethernet and has a length of 100m. Most cables are unshielded, relying on the twisted pair design for noise rejection, and some are shielded. The computer shop uses 568 A standards in their UTP cable color coding. They also obsolete a cable type of straight through.

GIGABIT ETHERNET (GbE or 1 GigE)

Is a term describing various technologies for transmitting Ethernet frames at a rate of a gigabit per second, as defined by the IEEE 802.3-2008 standard. Half-duplex gigabit links connected through hubs are allowed by the specification but in the marketplace full-duplex with switches are normal.

NETWORKING EQUIPMENTS

Network switch is a computer networking device that connects network segments. The term commonly refers to a network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (layer 3 and above) are often referred to as Layer 3 switches or multilayer switches.

The term network switch does not generally encompass unintelligent or passive network devices such as hubs and repeaters. The first Ethernet switch was introduced by Kalpana in 1990. The network switch, packet switch (or just switch) plays an integral part in most Ethernet local area networks or LANs. Mid-to-large sized LANs have a number of linked managed switches.

A router is an electronic device that is used to forward data between computer networks. The company uses 1 Dlink router and 2 Edimax switches. The router has 4 ports while the switch has 32 ports.

Product Documentation

The network switch, packet switch (or just switch) plays an integral fragment in most Ethernet local region networks or LANs. Mid-to-large sized LANs contain a number of linked managed switches. Small office/home office (SOHO) applications typically use a single switch, or an all-purpose converged device such as gateway access to small office/home broadband services such as DSL router or cable Wi-Fi router. In most of these cases, the waste user device contains a router and components that interface to the particular physical broadband technology, as in the Linksys 8-port and 48-port devices. User devices may also include a telephone interface to VoIP.

In the context of a standard 10/100 Ethernet switch, a switch operates at the data-link layer of the OSI model to get a different collision domain per switch port. If you have 4 computers A/B/C/D on 4 switch ports, then A and B can transfer data between them as well as C and D at the same time, and they will never interfere with each others’ conversations.

In the case of a “hub” then they would all have to share the bandwidth and run in Half duplex. The result is that there would be collisions and retransmissions. Using a switch is called micro-segmentation. It allows you to have dedicated bandwidth on point to point connections with every computer and to therefore run in Full duplex with no collisions.Manufacturer: Edimax

CONTIGENCY PLANNING

If there are problems or failure in internet connection they must confirm first the numbers of users that are connected in one server, to verify if it is one of the causes to comprise a downtime. The company may have an option to replace computer components, such as hard disks and network adapters, to continue the connections if they have available or extra networking equipments, and to let their customer change the terminal they use to another for the mean time. They also must have reserved other internet line.

INTERNET CONNECTIVITY OR NETWORK MANAGEMENT

LAN AND WAN CONNECTIVITY

Local area network (LAN) is a computer network covering a small physical area like a computer shop; it is connect the entire pc terminal to make use for games and to share information to one another. It is very important to the costumers especially the gamers to connect to their virtual game. Wide area network (WAN) is a computer network that covers a broad position. They are not unlike a huge company that require a WAN but in comes to connectivity in the procure.

Using the internet the costumer are using so for they can explore and manage to surf to the network Dedicated dial-up uses a standard phone connection between your computer network and our POP. The data rate is up to 56 kbps and is venerable primarily by individuals and companies in a transitional plot between needing full-time connectivity to the internet and having the resources to commit to frame relay or point to point. Due to the nature of dial-up lines, this option has much lower reliability and throughput than ISDN, frame relay or point to point connectivity. Dedicated dial-up is best suited for a growing internet access needs that are not dependent upon high reliability or committed data rates.

Frame Relay is the most cost-effective full-time connection for medium to high rush Internet access. In almost all cases, your costs will be less than veteran leased-line connections and even ISDN. You can easily increase the bandwidth of your Internet connection as your needs grow. Compared to aged leased line access, with frame relay you only pay the phone company for the bandwidth you need and there is no mileage charge. In most cases, ISDN calls from a business location are ‘metered’ and can result in unexpectedly high monthly charges by the phone company if you maintain a full-time connection. Frame relay access to the Internet consist of two determined components. In addition to the Internet access fees, you will also need the frame relay circuit from your facility to the phone company’s local central office. The rest of the circuit costs are paid by Minnesota OnLine and are included in your monthly access fees.

Please call Minnesota OnLine for an estimate or quote of your circuit costs. Minnesota OnLine will order and coordinate the install and testing of your circuit with your local phone company. Point-to-point high-speed digital dedicated service gives you complete access to the Internet including e-mail, the World Wide Web, Gopher, file transfer, and Usenet newsgroups with enhanced bandwidth for faster response. This service is provided over dedicated circuits from your station directly to our network hub.

Access speed (bandwidth) is available at various levels: 33 kbps, 56 kbps, 128 kbps, 256 kbps, 1.54 Mbps, and transparent LAN connections at 10 Mbps. Pricing for Dedicated Services consists of a one-time setup fee, monthly service fee, and telecommunications costs (where applicable). Additional equipment may be needed for your network to take advantage of this increased bandwidth. A dedicated high-speed connection can greatly reduce multiple individual connectivity costs and allow greater ability to manage data that traverses your network. Some of the benefits of Dedicated Service are:

Costs are contained for additional users
Security is enhanced with a single point of entry
Internet accessibility for all users can be easily managed
Increased bandwidth for all users
Increased rush of data transmission
Full time connectivity
Transparent use for end-users
No additional telco charges

SECURITY

RESTRICTION AND PRIVILEGES

The Sonic Computer Shop uses I-Cyber Café Software. It has its Print Monitoring that automatically charged customers for printing, uses distinct rates for monochrome and color printing. It also automatically locks each terminal to prevent an unauthorized use of a computer. Protect it from logging in via Ctrl-Alt-Del, etc. Point To a customer session time or money left after login. It also has a message box that a client can employ to send message to the server if they need to say something. It also keeps track of the Internet websites and pages which a customer opens while they are surfing the internet. Using Cyber Cafe Software the Sonic Computer Shop has the privileges to restrict a sure web site that they want to block like adult websites. With these privileges the viruses or any malicious programs can be prevented. And this is more favorable if they have minor customers. With this software it can secure that all terminals is automatically being monitored that no one can easily access or utilize the computers without the authority from the server.

FIREWALL, ANTI VIRUS AND DEEPFREEZE APPLICATION

Sonic Computer Shop uses AVG Anti Virus Free Edition, Avast Free Edition and Comodo Firewall. They consume two Anti Virus to filter all the files that may have viruses in computers. AVG is an umbrella term for a range of anti-virus and Internet security software for the Microsoft Windows, Linux, and FreeBSD computing platforms, developed by AVG Technologies, a privately held Czech company formerly known as Grisoft. Avast Antivirus is an antivirus program developed by ALWIL Software as, a company based in Prague, Czech Republic.

It is a multiple recipient of the Virus Bulletin VB100 Award, for detection of 100% of “in-the-wild” viruses, and is a past winner of the Secure Computing Readers Trust Award Comodo Firewall Pro (CFP; previously COMODO Firewall) is a freeware firewall developed by Comodo Group that provides protection on a Microsoft Windows operating system from both inbound and outbound attacks. Comodo also has an open source firewall for Linux based systems called Trustix. In an independent review consisting of leak tests in 2009, the freeware software Comodo Firewall Pro version 3 received 100% on all tests.^[3] Version 3.0 includes HIPS (Host Intrusion Prevention System) technology called Defense+, to protect a computer from unknown attacks. Comodo Firewall Pro has been integrated into Comodo Internet Security.

CONTINGENCY PLANNING

If their AVG Anti-Virus or Avast Anti Virus Free Edtion has been expired or malfunctioned, they can download another anti virus like AOL Active Virus Shield, Avast Professional Edition, Avira Professional Edition or Free Edtion and many more. There are many anti virus that are downloadable from www.google.com and www.yahoo.com that they can use, and most of them has a free edition and easily to update from the internet. For the security of their computer shop they must have at least a hidden camera that can help them to monitor their customers while using their computers. It is very useful because if there are times that their authorized personnel left for just a moment and somebody theft some stuff or even went to their server and do something unethically they can easily recover to that scenario to study who is responsible for that incident.

RECOMMENDATION

The proponents of the seek recommends to the owner of the computer shop to at least have a renovation inside their computer shop. This is to removal a small wall divider beside their comfort room, for a bigger space. The proponents also recommend adding one air conditioner in their second floor and if they have extra budget, they may change the location of their air conditioner in their first floor in their ceiling for a cooler space. The proponents also recommend Mr. Andres to have a surveillance camera for their security purposes.
