Kindly elabortae the method by using which computers use the binary number system to convert data in to binary form.

Hi all! This seems way too difficult for me, let me try to explain the OS binary conversion formula.

Hi Docsity Community, can some one provide information on the following description question.

" In CDMA, each user is assigned a unique code. For data of binary 1 that code is transmitted and for binary 0 complement of the code assigned to the user is used. If using 4 chips for a bit then the bandwidth required is 4 times to what is originally required for same data rate. Now to come at par at least 4 users must be accommodated in this 4-times bandwidth. Suppose a user is assigned the code 0000. For the remaining 3 users, from the list below pick 3 more codes such that all the users have codes which are orthogonal to each other."

How to load divisor values in the Interval timer

Write a C program In this program, you will access internal PC speaker by using port 61H. Least two significant bits of port 61H are used for connecting PC speaker to Interval Timer

Calculate Command Byte according to following criteria:

a. Channel: 2 b. Interval Timer Mode: 2 c. Counter: Binary d. Divisor bytes to be loaded: All (For calculating divisor value, read instruction 4)

You will first load last four digits of your Student ID as a divisor value (see the purple color digits in below example ID), and then after a delay of 2 seconds, you will again load new divisor value which will be next four digits of your Student ID (see the orange color digits in below example ID).

BC1 2345 6789

For producing delay, use Timer Count, a double word variable in the BIOS data area which is placed at the location 0040:006C
After loading each divisor value, turn on the PC speaker
You can check the output of the program by booting your system in DOS mode and then running the exe file. But does not worry if PC speaker does not produce sound; the host operating system may restrict you to directly access PC speaker. Just focus on the concepts.

Your assignment file should be a single Word file (.doc or .docx) containing complete code

list and describe networking technologies along with sutiable example for each technology

In information technology, networking is the construction, design, and use of anetwork, including the physical (cabling, hub, bridge, switch, router, and so forth), the selection and use of telecommunication protocol and computer software for using and managing the network, and the establishment of operation policies There are several different types of computer networks. Computer networks can be characterized by their size as well as their purpose. The size of a network can be expressed by the geographic area they occupy and the number of computers that are part of the network. Networks can cover anything from a handful of devices within a single room to millions of devices spread across the entire globe. Some of the different networks based on size are:

Personal area network, or PAN
Local area network, or LAN
Metropolitan area network, or MAN
Wide area network, or WAN

In terms of purpose, many networks can be considered general purpose, which means they are used for everything from sending files to a printer to accessing the Internet. Some types of networks, however, serve a very particular purpose. Some of the different networks based on their main purpose are:

Storage area network, or SAN
Enterprise private network, or EPN
Virtual private network, or VPN

Let's look at each of these in a bit more detail. Personal Area Network A personal area network, or PAN, is a computer network organized around an individual person within a single building. This could be inside a small office or residence. A typical PAN would include one or more computers, telephones, peripheral devices, video game consoles and other personal entertainment devices. If multiple individuals use the same network within a residence, the network is sometimes referred to as a home area network, or HAN. In a very typical setup, a residence will have a single wired Internet connection connected to a modem. This modem then provides both wired and wireless connections for multiple devices. The network is typically managed from a single computer but can be accessed from any device. This type of network provides great flexibility. For example, it allows you to:

Send a document to the printer in the office upstairs while you are sitting on the couch with your laptop.
Upload a photo from your cell phone to your desktop computer.
Watch movies from an online streaming service to your TV.

If this sounds familiar to you, you likely have a PAN in your house without having called it by its name. Local Area Network A local area network, or LAN, consists of a computer network at a single site, typically an individual office building. A LAN is very useful for sharing resources, such as data storage and printers. LANs can be built with relatively inexpensive hardware, such as hubs, network adapters and Ethernet cables. The smallest LAN may only use two computers, while larger LANs can accommodate thousands of computers. A LAN typically relies mostly on wired connections for increased speed and security, but wireless connections can also be part of a LAN. High speed and relatively low cost are the defining characteristics of LANs. LANs are typically used for single sites where people need to share resources among themselves but not with the rest of the outside world. Think of an office building where everybody should be able to access files on a central server or be able to print a document to one or more central printers. Those tasks should be easy for everybody working in the same office, but you would not want somebody just walking outside to be able to send a document to the printer from their cell phone! If a local area network, or LAN, is entirely wireless, it is referred to as a wireless local area network, or WLAN. Metropolitan Area Network A metropolitan area network, or MAN, consists of a computer network across an entire city, college campus or small region. A MAN is larger than a LAN, which is typically limited to a single building or site. Depending on the configuration, this type of network can cover an area from several miles to tens of miles. A MAN is often used to connect several LANs together to form a bigger network. When this type of network is specifically designed for a college campus, it is sometimes referred to as a campus area network, or CAN. Wide Area Network A wide area network, or WAN, occupies a very large area, such as an entire country or the entire world. A WAN can contain multiple smaller networks, such as LANs or MANs. The Internet is the best-known example of a public WAN. Private Networks One of the benefits of networks like PAN and LAN is that they can be kept entirely private by restricting some communications to the connections within the network. This means that those communications never go over the Internet. For example, using a LAN, an employee is able to establish a fast and secure connection to a company database without encryption since none of the communications between the employee's computer and the database on the server leave the LAN. But, what happens if the same employee wants to use the database from a remote location? What you need is a private network.
