How Cloud Computing can make a small company look big

Using Cloud Computing can make you company look larger than what it really is. If a small company wants to have a website they can. There are many different companies that will host your website and if you need them to design it they will do that also. It is also nice to have your domain and email address match. This allows a company in a small town to reach all over the world for a small cost. The company can have a toll free fax line for less than a basic phone line.  With this fax line you can send faxes from your computer or receive faxes to you email or check it on the internet. With this fax system you can check your faxes as long as you have access to the internet or check you email.  You can also have your faxes sent to more than one email address. Most companies use a Post Office Box that does not tell you the size of the company.

When a small business is just starting out, they want to look bigger that what they are. These are just a few things that they can do to reach more people and look larger than what they are for a small coast. When a company large or small looks professional customers feel secure about doing business with that company.

Healthy Computer means Healthy Network

It is important to keep a healthy computer and network. It is also important to keep current version antivirus software and malware. I was working on my computer checking my email, and a program open and started scanning my laptop. I let the software scan my laptop, because I thought it was my antivirus software. When the program finished scanning I clicked the remove button. The screen went out to a website called System Tool and it wanted me to buy the software. I closed the browsers and every time I tried to open a program I would get a warning message from system tool. It would open not let me open any program. I spent over an hour trying to remove that software. I could not even open my antivirus software so I could run it.

After trying for over an hour to remove the software, I booted my laptop up in safe mode. In safe mode I could run different programs. I downloaded Malware Bytes and then I installed it. While in safe mode the malware found two viruses and removed them.  I rebooted my laptop and ran the malware again and it did not find any viruses. I also ran my antivirus software and the antivirus software found no viruses. Now my computer is clean and I want to keep it clean.

 Some things you can do to keep my computer and your network healthy. Do a disk clean, then and disk defragmenter once a week. This will help keep your files organized and your computer will run faster. Secondly do a full antivirus scan they will help to keep your computer and network healthy. Some ISP offers some kind of antivirus software for free. Finally back up of your computers at least once a month, to an external hard drive. If you have tried everything to fix your computer and you still cannot correct the problem, or if your computer has crash, you will be able to restore everything from the last backup.

Monitoring Software

Companies monitor their network for many reasons; they want to keep track of traffic and the devices on the network. There are various different monitoring tools that can be used.  Monitoring your network is very importing it keeps you on top of what is going on your network. Monitoring your network will also allow you to determine the amount of bandwidth that is being used. You will also be able to ascertain what programs are running and you how much bandwidth it is using. Knowing what programs are running and how much resource it is using then you can manage your network better. Knowing how much resource is needed for different programs is very important. If you have a program that is a resource hug; running it during high peak time will slow down your network or crash it.

There are many different programs that you can use to monitor your network. Each company is different, and the monitoring system that is used depends on the needs of the company. If your company has network equipment that needs to me up and running you need to know as soon as possible when it goes down. Know when a device goes down you will need to know what caused it to go down. If there is too much traffic going to a device it could cause the device to crash or you will not be able to get data.

Another thing you will need to know if you want to monitor you network remotely or just on site. Some things you should look for in monitoring software are PC monitoring and administrative control. You will need to be able to filter and block websites, and ports. A very important feature of any program is to be able to retrieve reports. Below are some website that

Basic Information on IPv4 and IPv6

IPv4 is running out of IP addresses there are more things using IP address then before. More people have computers, network printers, wireless devices that require an IP. The internet is growing and each Domain name needs an IP address. With IPv4 there are five IP groups, Class A, Class B, Class C, Class D, and Class E. 

Class	Address Range	Supports
Class A	1.0.0.0    to 126.255.255.255	16 million hosts on each of 127 networks
Class B	128.1.0.1    to 191.255.255.254	65,000 hosts on each of 16,000 networks.
Class C	192.0.1.1    to 223.255.254.254	254 hosts on each of 2 million networks
Class D	224.0.0.0    to 239.255.255.255	This is reserved for multicast groups
Class E	240.0.0.0    to 254.255.255.254	This is reserved for research and development

IPv4 only uses 28 bits but with IPv6 it uses 128 bits.The differences between IPv6 and IPv4 are in five major areas: addressing and routing, security, network address translation, administrative workload, and support for mobile devices. IPv6 also includes an important feature: a set of possible migration and transition plans from IPv4. IPv4 has 4,294,967,296 IP addresses and IPv6 has about 340,282,366,920,938,463,374,607,431,768,211,456. IPv6 is a classless scheme. Classless means that you do not have to include the subnet mask. IPv6 is structured with the first 64 bits are used for network identification and the last 64 bits are for the host identification.

Two types of Network Address

There are 2 different types of network addresses, one is a MAC (Media Access Control) address and the other one is an IP (Internet Protocol) address. The MAC address is a physical address and it exists on the Layer 2 (Data Link) of the OSI (Open Systems Interconnection). Layer 2 is also known as the Data Link Layer.  The IP address is a virtual address and it operates on Layer 3 (Network).

MAC addresses are unique address it is burnt into the hardware by the manufacture at the time it is made.  MAC addresses are also known as Burned In Addresses (BIA). MAC address are used by many different Layer 2 devices some are Ethernet, Token Ring, Bluetooth, and Fibre Channel.

MAC address is 48 bits in length and there are 281,474,976,710,656 possible addresses. A MAC address would look like this 00-23-4E-47-21-01. The first three bytes of any MAC address will tell you who the manufacture of that device is. The manufacture of this address 00-23-4E is Hon Hai Precision Inc. Co., Ltd., 66 Chung Shan RD. Tu-Cheng, Taipei Hsien Taiwan 236. The first three bytes of a MAC address are assigned by the IEEE Standards Association to a company (http://www.tech-faq.com/mac-address.html).

 IP address is an Internet Protocol address. The IP address is used to identify the different computers and websites on the internet or intranet. Each device must have a unique IP address. If not it will cause problem on your network. The IP address allows you chat, send email, and it allows you to use the internet

An IP address is made up of 4 separate numbers, each between 0 and 255, and arranged with dots in between them.  All websites have an IP address. It is easier for humans to remember a name instead of an IP, so a DNS (Domain Name System) matches the name with an IP address. One of Yahoo.com’s IP addresses is 209.161.122.70. IP address is controlled by ICANN (Internet Corporation for Assigned Names and Numbers). The website for them is http://icann.org.

The internet is growing so fast that we are running out of IPv4 address. Soon we will be out of IP and we will need to use IPv6.

How to install a LAN Network

The first thing is to have the right equipment. If you have the internet then you have most of what you need. You will need a computer, printer, hub or switch, Ethernet cable, and sometimes modem or router. If you have access to the internet then your ISP (internet service provider) has provided you with a modem or a router.  

If you have a fairly new laptop then you would want to have a WLAN (Wireless Local Area Network). A wireless network will give you the freedom to move around freely. The equipment that you would need for the WLAN is a Wi-Fi router. There are four different types of wireless access point A, B, G and N. N protocol has the longer range. B and G is about 100 feet for in unobstructed area. N has a range of about 700 feet.

Connect your computers, printers, to your hub or switch using an Ethernet cable. If you want to connect to the internet then you will need to connect you hub or switch to the ISP’s modem. If you have a Wi-Fi router, you will need to install it. Connect the switch or hub to the Ethernet port on the router using your Ethernet cable. Using an Ethernet cable plug one end of the cable into the internet port on the router, and the other end of the cable to the Ethernet port of the modem connect the router to the modem. Now you have set up your LAN.   

What is a Network (Computer Network)

Computer network is also: two or more computers that are connected together to share resources such as hardware, data, and software. Most common are the local area network (LAN) and the wide area network (WAN). A LAN can range from a few computers in a small office to several thousand computers spread throughout dozens of buildings on a school campus or in an industrial park. Expand this latter scenario to encompass multiple geographic locations, possibly on different continents, and you have a WAN

Networks (Computer Network) is two or more computers that are connected together for the purpose to share resources, information, or software. There are different types of Networks, LAN (Local Area Network), WAN (Wide Area Network), WLAN (Wireless Local Area Network), MAN (Metropolitan Area Network), and SAN (Storage Area Network, System Area Network, Server Area Network, or even Small Area Network)

 Everyone uses some kind of network today it may be a LAN, WAN or the one that is becoming very popular today the WLAN. Today children are using computers in elementary school and to get school assignments, and to do school assignments. A computer today is almost like MP3s and DVDs all most every American family owns at least one of them.

So because you have a computer does that mean you are a part of a network? If you have at least one child chances are you have internet access. If you have internet access you are using a WAN. You are connecting to the WWW (World Wide Web) maybe to play games, or go to Facebook. You may also have a desktop, printer, and a laptop. Both computers are sharing the printer that means they are on a LAN. You are sharing resources on a LAN.
