WEEK 8: INSTALL AND CONFIGURE APPLICATIONS BUNDLED APPLICATIONS - Bundled applications are software programs that are sold together as a set or suite or that are sold with an operating system or with a new computer. - Examples of software suites include Microsoft Office and Google Apps. Some applications commonly bundled with a new computer include security software that might combine antivirus, antispyware, and antimalware programs with firewalls and other security utilities. SOFTWARE INVENTORY - A software inventory is a listing of the applications that are available on a computer - You can perform a manual inventory by identifying the various applications that are installed, or you can use an inventory utility to create the inventory list. For example, you can use programs such as Belarc Advisor - Free Personal PC Audit and Microsoft Software Inventory Analyzer (MSIA) to create a detailed profile of the hardware and software installed on a computer. DESIRED APPLICATIONS A web browser. An email client. Word processing software. Security software. Software updates, including OS updates. BLOATWARE - As the cost of RAM and disk storage continues to decrease, there has been less emphasis among software developers to optimize the size of applications and the resources required to run those applications. - Bloatware is a slang term that describes software that has lots of features and requires considerable disk space and RAM to install and run. APPLICATION SHARING Depending on the application being installed, you might have the opportunity to specify whether the application will be available to only your account or shared with all users on the computer. Typically, desktop applications installed on the computer are available to any account on that computer, with the proper permissions.

WEEK 9: NETWORK CONNECTION TYPES COMPUTER NETWORKS A computer network is a group of computers that are connected together to communicate and share network resources such as files, applications, and devices. No two computer networks are alike in size or in configuration. Each network, however, includes common components that provide the resources and communications channels necessary for the network to operate. Downloaded by Cydrick Descalzo ([email protected])  lOMoARcPSD|46744989 TYPES: LAN MAN WAN NETWORK CONNECTIONS Wireless Wired Cellular WIRELESS NETWORK CONNECTIONS A wireless computer network is a network in which computers use wireless connections to link with other computers. Wireless connections transmit data by using radio frequency waves. Wireless networks can connect a few devices over short distances, such as within a home or an office, or can be set up to connect computers over large distances through the Internet. Wireless networks offer affordability, ease of use, and greater mobility for the user. WIRED NETWORK CONNECTIONS Wired computer networks use a technology called Ethernet. Ethernet is a set of networking technologies and media access methods specified for LANs. It allows computers to communicate over small distances using a wired medium. Networks both large and small use Ethernet to provide both backbone and end-user services. SOHO NETWORKS A SOHO network is a network that provides connectivity and resource sharing for a small office or home office. Generally limited to fewer than 20 computers or nodes, a SOHO network often facilitates sharing of files and printers, as well as services such as email, faxing, and so forth. A SOHO network can contain a combination of wired and wireless computer connections, and all of the computing devices in a SOHO network usually share the same physical location. SERVICE SET IDENTIFIERS (SSIDS) A Service Set Identifier (SSID) is a 32-bit alphanumeric string that identifies a WAP and all the devices attached to it. A WAP typically broadcasts an SSID in plain text. It is more appropriate to think of an SSID as a network name that is applied to the grouping of the WAP and the devices currently connected to it. Wireless connectivity devices such as a WAP or other wireless routers come with a default SSID. Instead of accepting the device’s default SSID, you should manually specify an SSID to more clearly identify the device. FIRMWARE Firmware is specialized software that is stored on a hardware device’s read-only memory (ROM) whether or not the device is powered. It is most often written on an electronically reprogrammable chip so that it can be updated with a special program to fix any errors that might be discovered after a computer is purchased, or to support updated hardware components. Downloaded by Cydrick Descalzo ([email protected])  lOMoARcPSD|46744989 Router firmware may need an upgrade from time to time depending on manufacturer updates. These updates contain security patches, updates to performance, and updates to address any known issues. The updates can be installed in a number of ways, but most commonly can be downloaded from the manufacturer’s website. ROUTER SETUP PROCESS 1. Verify the wired connection, if applicable. 2. Configure encryption standard (WEP, WPA, or WPA2). 3. Change SSID from default. 4. Apply a new wireless password. 5. Change the admin password for the router. 6. Connect to the new network. 7. Verify the Internet connectivity. 8. Update firmware, if necessary INSTALL AND CONFIGURE A SOHO ROUTER 1. If you are deploying a wireless router, choose the appropriate 802.11 router for your needs, whether it be 802.11a, b, g, or n. 2. Choose a location for the router. 3. Connect the router to a power source and turn it on. 4. Connect the router to a cable or DSL modem via Ethernet or USB cable. After plugging in the cables, you may need to turn the router off and on to verify that the router has recognized the modem. 5. Connect a computing device to the router. If you are deploying a wireless router, use a cable for the initial router configuration. Once the router configuration is completed, you can remove the cable and connect wirelessly. 6. Navigate to the router’s administrative utility. You may need to refer to the router’s user manual, but in most cases, you can open an Internet browser and enter http://192.168.1.1. 7. Enter the information needed to connect the router to the Internet. The exact information will depend on how you are subscribing to an ISP. If you are using DSL, then you may need to enter a specific user name and password issued to you by the ISP. If you have been asked to use a static IP address, then you may need to enter the address issued to you by the ISP. 8. Configure the router settings according to your needs. For a wired router, change the default user name and password. For a wireless router, make sure that you update the SSID and change the default user name and password. 9. If necessary, create an access control list for the router to control which users or computers can access it. 10. Verify that you can connect to the Internet by opening a browser and performing a search. 11. Configure the security settings in the administrative utility. 12. Connect additional computing devices to the router. WEEK 10: NETWORK AND ALTERNATIVE TECHNOLOGIES VIRTUALIZATION Downloaded by Cydrick Descalzo ([email protected])  lOMoARcPSD|46744989 virtualization software allows for one physical device, such as a server operating system, to host multiple logical operating systems. These logical systems are called virtual machines. CLOUD COMPUTING Cloud computing is a computing infrastructure in which resources, such as storage and applications, are hosted in a distributed fashion by a third party over the Internet. The
