Atanasoff-Berry Computer (ABC), an early digital computer. It was generally believed that the first electronic digital computers were the Colossus, built in England in 1943, and the ENIAC, built in the United States in 1945. However, the first special-PURPOSE electronic computer MAY actually have been invented by John Vincent Atanasoff, a physicist and mathematician at Iowa State College (now Iowa State University), during 1937–42. (Atanasoff also claimed to have invented the term ANALOG computer to describe machines such as Vannevar Bush’s Differential Analyzer.) Together with his graduate assistant Clifford E. Berry, Atanasoff built a successful small prototype in 1939 for the purpose of testing two ideas central to his design: capacitors to store data in binary form and electronic logic circuits to perform addition and subtraction. They then began the design and construction of a larger, more general-purpose computer, known as the Atanasoff-Berry Computer or the ABC.

Answer:

pictogram or ideogram

Explanation:

In computing, an icon is a pictogram or ideogram displayed on a COMPUTER screen in order to help the user navigate a computer system. The icon itself is a quickly COMPREHENSIBLE SYMBOL of a software tool, function, or a data file, accessible on the system and is more like a traffic sign than a detailed illustration of the ACTUAL entity it represents.[1] It can serve as an electronic hyperlink or file shortcut to access the program or data. The user can activate an icon using a mouse, pointer, finger, or recently voice commands. Their placement on the screen, also in relation to other icons, may provide further information to the user about their usage.[2] In activating an icon, the user can move directly into and out of the identified function WITHOUT knowing anything further about the location or requirements of the file or code.

Icons as parts of the graphical user interface of the computer system, in conjunction with windows, menus and a pointing device (mouse), belong to the much larger topic of the history of the graphical user interface that has largely supplanted the text-based interface for casual use.

Answer:

1. WiMAX:  

i. The ‘World Interoperability for MicroAcess, Inc. (WiMAX)’ forum, an industry group, focuses on creating advanced technology solution for high speed wide AREA internet access.

ii. The WiMAX product certification program ensures interoperability between WiMAX equipment from vendors worldwide.

iii. WiMAX can serve as a backbone for 802.11 hotspots for connecting to the internet. Alternatively, users can connect mobile devices such as laptops and handsets directly to WiMAX base stations. Mobile devices connected directly can achieve a range of 4 to 6 miles.

iv. There are 2 types of WiMAX, fixed WiMAX(IEEE 802.16d-2004) and mobile WiMAX(IEEE802.16e-2005). Fixed WiMAX is a point-to-multipoint technology, whereas mobile WiMAX is a multipoint-to-multipoint technology, similar to that of a cellular infrastructure.

2. Some of the salient features supported by WiMAX are:

i. High data rates: - WiMAX can typically support data rates from 500 Kbps to 2 Mbps. - The inclusion of multi-input multi-output(MIMO) antenna techniques along with flexible sub-channelization schemes, advanced coding and modulation all enable mobile to support peak downlink data rates of 63 Mbps per sector and peak uplink data rates of up to 28 Mbps per sector in a 10 MHz channel.

ii. Quality of service (QoS):

WiMAX has clearly defined QoS classes for applications with different requirements such as VoIP, real time video streaming, file transfer and web traffic.

iii. Scalability:

Mobile WiMAX is designed to able to work in different channelization from 1.25 to 20 MHz to comply with varied world-wide requirements.

iv. Security:

There is support for diverse set of user credentials like SIM/USIM cards, smart cards, digital certificates, username/password schemes.

All this is based on relevant ‘extensible authentication protocol (EAP)’ methods for credential type.

v. Mobility:

Mobile WiMAX supports optimized handoff schemes with latencies less than 50ms to ensure that real time applications such as VoIP can be performed without service degradation.

Flexible key management schemes assume that security is maintained during handoff.

3. WiMAX Physical Layer (PHY):

i. For bands in 10-66GHz range, 802.16 defines one interface called Wireless MAN-SC

ii. For 2-11GHz (both licensed and unlicensed):

Wireless MAN-SC (single carrier modulation)

Wireless MAN-OFDM (256 carrier OFDM with access to different stations using TDMA)

Wireless MAN-OFDM (2048 carrier OFDM by assigning subset of carriers to individual station)

iii. WiMAX PHY features include ‘Adaptive Modulation and Coding (AMC)’, ‘Hybrid Automatic Repeat Request (HARQ)’, ‘Channel Quality Indicator Channel (CQICH)’ which is a feedback channel.

iv. All these features provide robust link adoption in mobile environment at vehicular speeds in excess of 120Km/h.

4. WiMAX Medium Access Control (MAC):

i. Each subscriber station need to compete for media only one (for entry).Then, WiMAX base station provides time slot to each subscriber station which MAY increase or decrease depending on need.

ii. There is a scheduling algorithm for service to each station. This algorithm is robust and not affected by over loading and over subscription.

iii. WiMAX supports different transport technologies such as IPv4, IPV6 and Ethernet.

iv. WiMAX mesh networking allows subscriber stations to communicate with each other i.e. “Subscriber” mode and with base station i.e. “base station” mode simultaneously.

5. Spectrum Allocation for WiMAX:

i. The biggest spectrum segment for WiMAX is around 2.5GHz.

ii. The other bands are around 3.5HZ, 2.3/2.5GHz, or 5GHz, with 2.3/2.5GHz.

6. Other features:

i. The mesh mode of WiMAX enables subscriber stations to relay traffic to one another. Thus, a station that does not have line-of-sight with the base station can get its traffic from another station.

ii. WiMAX technology can provide fast and cheap broadband access to markets that lack infrastructure (fiber optics, copper wire), such as rural areas and unwired countries. WiMAX can also be used in backup during disasters, which may lead the wired networks to get broken down.

iii. As mobile WiMAX is scalable in both radio access and network architecture, it provides flexibility in network deployment options and service offerings.

iv. Mobile WiMAX based on 802.16e uses OFDMA in which carriers are divided among users to form sub channels. The coding and modulation are adapted SEPARATELY for each sub channel.

v. SOFDMA is an enhancement of OFDMA that scale the number of subcarriers in a channel with possible values of 128, 512, 1024, and 2048.

vi. 802.16e includes power-saving and sleep modes to extend battery life if mobile devices.

vii. 802.16e also supports hard and soft handoff to provide users with seamless connections as they move across coverage areas of ADJACENT cells.

Answer:

There is a whole lot of difference between a DESKTOP computer and a washing MACHINE although both run of programs that are present. Hence the statement is not correct. A desktop computer stores the files that are written on them but a washing machine can only follow a diverse SET of commands only for washing clothes. It is the computer that makes the PROGRAM for the washing machine to run and not otherwise.

ANSWER:

Compiler transforms code written in a high-level programming language into the machine code, at once, before program runs, whereas an Interpreter COVERTS each high-level program statement, ONE by one, into the machine code, during program run. Compiled code runs faster while interpreted code runs SLOWER.

Answer:

Difference Between Assembly Language and MACHINE Language. ... Machine language is a language that has a binary form. It can be directly executed by a computer. While an assembly language is a low-level programming language that REQUIRES SOFTWARE CALLED an assembler to convert it into machine code.

Here I will show you step-by-step how to convert the decimal number 15 to binary.

First, note that decimal numbers use 10 digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) and binary numbers use only 2 digits (0 and 1).

As we explain the steps to converting 15 to binary, it is IMPORTANT to know the NAME of the parts of a division problem. In a problem like A divided by B equals C, A is the Dividend, B is the Divisor and C is the Quotient.

The Quotient has two parts. The Whole part and the Fractional part. The Fractional part is also known as the Remainder.

Step 1) Divide 15 by 2 to get the Quotient. Keep the Whole part for the next step and set the Remainder aside.

Step 2) Divide the Whole part of the Quotient from Step 1 by 2. Again, keep the Whole part and set the Remainder aside.

Step 3) Repeat Step 2 above until the Whole part is 0.

Step 4) Write down the Remainders in reverse order to get the answer to 15 as a binary.

Here we will show our work so you can follow along:

15 / 2 = 7 with 1 remainder

7 / 2 = 3 with 1 remainder

3 / 2 = 1 with 1 remainder

1 / 2 = 0 with 1 remainder

Then, when we put the remainders together in reverse order, we get the answer. The decimal number 15 converted to binary is therefore:

1111

So what we did on the page was to Convert A10 to B2, where A is the decimal number 15 and B is the binary number 1111. Which MEANS that you can display decimal number 15 to binary in mathematical terms as follows:

1510 = 11112
