Hello i m BAL and i am a cool dude

Chapter 8.9

This part of the chapter talks about NIC which stands for Network Interface Card. This NIC is required to connect to the internet. The NIC can be preinstalled or you may need to buy one for your own.

In order for the NIC to work you need to download the driver for it and then it will be ready to connect to the internet.

You many also need to install a modern additonal to the NIC which will also help you to connect to the internet.

MAC address:  In computer networking, a Media Access Control address (MAC address) is a unique identifier assigned to most network adapters or network interface cards

IP Address (including an example): IP address lookup, location, proxy detection, email tracing, IP hiding tips, user forums, and more. Find, get, and show my IP address.

Subnet masks: The IP Subnet Mask Calculator enables subnet network calculations using network class, IP address, subnet mask, subnet bits, mask bits, maximum required Ip address

Hub: HUB, Hubs or HUBS may refer to: [edit] Technology. [Edit] Wheels. The central part of a Wheel · Bicycle hub, the central part of a bicycle wheel…

Switch: A network switch or switching hub is a computer networking device that connects … If you have 4 computers A/B/C/D on 4 switch ports

In this blog i will be talking about different types of scanners and how each different scanner functions.

The first scanner that i will talking about is the FLATBED SCANNER this scanner is often usedto scan books and photographs. The FLATBED SCANNER has a sheet feeder to scan multiple images. The FLATBED SCANNER works like this it has a scanner head which consists of an array of image sensors, which lie beneath the glass and move along the item, whilst capturing the image.

The second scanner is HANDHELD SCANNER which a scanner which is portable small scanner. When using this scanner it is difficult to scan an image so you need to carefully pass the scanner head across the item that you want to scan.When a largeritem is scanned which is bigger than the handhel scanners head you must make more than one pass to capture the full image.  It could be very difficult to recreate the image but the images must beput back into one full single image of the item which was scanned.

The third types of scanner is a DRUM SCANNER which produces a high-quality transfer of an image. This scanner is usually used commercially and many drum scanner can also be used for high-end reproduction. An example of this could be phototgraphs in museums.  If you want to scan a image using the drum scanner, you need to attach the image to a revolving drumor load into a supporting canister. the drum inside the drum scanner roatates at very high speeds across optical scanner. The optical scanner carries on moving slowly across the drum until the whole of the image is completed and is captured. The captured image is then reproduced by the computer as a digital image file.

 

 

The last type of printer is ALL-in-one scanner which can scan,print send faxes and make copies, This scanner can do all the jobs that the scanners do above.

In one of the cisco lessons we got put into groups  of 3 or 4 pupils and were required to install a inkjet printer on to a desktop which functioned correctly. We also had to check if the printer was printing out the write files that we told it to. 

 

  

  

  

  

  

So in this presention i will show you how to install a printer onto a Desktop and show the steps how to install a printers drive correctly and easily.

In order to locate where the printer is placed on the desktop follow these steps.

First go to Start button and then click on Devices and Printer and you will see the print and faxes area were the printer will appear when you finished the installation

 

 

First of all you need to locate where the printer will be loaded when it is installed correctly

Then you will need to find out which printer and which model you are trying to install on to your desktop.

    

You will need a Printer USB Cable connecting the printer to the desktop for the data transfer data in order for the printer to print files.

Then find a website on the internet that allows you to download the correct drive for the printer and for the operating system.

 

 

 

 

After this, You will find a button that will allow you to download the driver of the printer, and let clcik on run in order for it to install the printers drive.

 Once the download is completed go back to the

 And check if the printer drive has been installed. The printers icon will appear like this if it has been installed correctly.

 

And then test the printer to check if it is working correctly and prints the right files that are needed.

 

For the intro for chapter 7 i have learnt many different types of printer which were:

Laser Printer are printers that use eletrophotographic technology and

Inkjet Printer are printers that use eletrostatic technology and finally the last one is

Dot Matrix Printer which uses impact technology

and i also learnt about the speed of a printer printing out paper which can be measured in PAGES PER MINUTES.

I also learnt about products cost and how realible they can be and what you would need to do to make sure you dont lose money and how different systems work in the business market work and finally we talked about the colours and quality of the print out and only uses 4 colours: Black, Cyan,Yellow, Magenta which are only needed to produces all the colours in the entire world.

And how you measure the quality of a print out which is dots per  inch DPI and the resolution of a image which can be low or high.

This chapter 6 talks about the laptop evolution and gives information and the history of laptops.  the first laptop that was produced was around 11lbs and its cost was 8 to 10 thousand dollars and was produced so astronauts   could take it to spaces for varies. the first ever laptop was produced which wa s called, “GRiD Compass 1101″. this was the start of laptops.

This chapter also shows the components that are used for the laptop and what advantages and disadvantages are about the laptop and what applications it occupies. it also talk about the dock station that the laptop is given with.It also shows all the parts of the laptop and labells the parts of the laptop so that we know what is what on a laptop.

It also compares desktops to laptop software and components and talks about their advantages and disadvantages of their features.

This chapter also talks about portable devices. It describes the feature of laptops.

A mobile phone is a electronic devices that allows people communcate with each other from different places. mobile phones differ in cordless phones which can only call someone if your network is in range. Mobile support many different accessories and services and also have bluetooth this allows 2 mobiles to transfer data within each other.

The most used application a mobile phone is SMS texting message with 74 % of active users.

The first ever phone was called, “Analog Cellular telephony” which had the capacity of 1 G it was introduced and produced by japan and was lauched in 1979 and the first modern phones was released in 1991 in finland which was a network technology on digital 2G.

Mobile phones have many feature incuding:

GPS navigation

Music MP3 and MP4 which is video included which sound

and many other features that are included in a mobile phone.

Mobile phones have to be charged in order for them to function and let all apllications run. these are charged by batteries that charge rechargable. mobile phones can be charged in a variety of ways:

For example:

Use USB cable that will be plugged into a base unit into a computer usb port that would allow the phone to be charged, they can also be charged if a AC adapter is plugged into a plug socket or even wireless charging that was released in 2009 but the first wireless charger was released for comsumers uses.

In order for the mobile phone to work you would need to insert a SIM for the phone to be able to connect to other people, if a SIM is not inserted the phone will send a screen message saying SIM is not insert which would not allow you to go any further to phone or to access your applications or services.

laptops have intergrated keyboards and a screen.theyalso have a touch pad that allows you to control the point where as you have a mouse and a keyboard on a desktops that can be inserted into the usb slot or into a port that lets the devices function. a Laptop is portable where as a desktop is not.

 

the laptop doesn not have a base unit and has a much smaller motherboard where as the desktop has a base unit and a much bigger motherboard. The components are smaller for the laptop so they can fit in the case

A laptop can run on AC power or rechargeable battery they also support hot swappable drivers and peripherals for example: Memory Stick, Cards and other Devices.

Because Laptops and Desktops are built different these means many parts are different for both of the source meaning the parts cannot be interchangeable, and the Desktop has many different slots on the motherboard that can be occupied by a card whilst the laptop only has 1 or 2.
